Spray booths for cars

Car repair and restoration is a popular car service. To carry out work on the restoration of the paint and varnish coating of the car, professional equipment is required. The spray booth creates optimal conditions for returning the exterior of the car to perfect condition.

Design features

Spray booth is a set of specialized equipment that is designed to safely carry out painting work at a high quality level. The design includes effective ventilation, which removes and neutralizes volatile substances.

Spray booth is an efficient equipment that saves resources. It creates ideal conditions for painting car body parts due to:

  • effective purification of incoming and outgoing air;
  • absence of stagnant zones;
  • optimal temperature conditions;
  • lack of glare.

The design uses air duct valves that prevent the penetration of dirt and dust from the external environment. Spray booths comply with the requirements of environmental standards, as air is removed outside that does not contain hazardous chemical compounds.

Saving energy resources is achieved due to the tightness of the spray booths. In the drying mode, the temperature is maintained at the required level, which speeds up the drying process of paintwork materials.

Types of spray booths

Spray booths differ in size, functionality, ventilation system. They are classified into the following types.

Passage and dead ends. In the first case, the supply and unloading are carried out in different ways, in the second – along the same path. Walk-through spray booths are more productive equipment compared to dead-end models.

With high pressure and vacuum.

Two- and single-engine. Single-motor chambers are equipped with ventilation valves that are installed in the floor. Powerful air currents created by the fan move the paint mist from top to bottom. Contaminated air passes through exhaust units located in the floor, where it is cleaned and released into the surrounding atmosphere. In twin-engine spray booths, fans are installed on both sides. They direct air flows to the filtration system, which allows for good circulation of the purified air masses.

Conditions for high-quality car painting

The process of applying and drying a multi-layer paint coating of car body parts requires the creation of certain conditions. Only professional spray booths can solve this problem:

A special environment is created for the high-quality performance of painting and drying operations. It does not contain pollution and dust, which provides the conditions for obtaining a smooth and even layer of coatings that does not have defects.

Optimum temperature conditions and humidity levels are maintained, which are necessary for sufficient tension of the paint film and to eliminate the appearance of haze.

Heating the air in the chamber and body parts shorten the drying time, which has a positive effect on productivity.

Safety is a must for any spray booth. To comply with this condition, structural parts are made of non-combustible materials: sheet steel for the walls and cement screed for the floor. All elements of the chamber have additional insulation, and the floor, walls and doors have increased fire resistance.

Good lighting simplifies the work of the master and prevents the appearance of highlights and shadows. The ventilation system is responsible for cleaning the air, which is equipped with effective filter elements.

Industrial hygiene is vital in some sectors for the development of their activity

The regulations are very demanding with some industries where asepsis and good hygiene are part of the production process

In this case, these companies have to get hold of top-tier suppliers that guarantee compliance with hygienic guidelines, so the chemical industry of cleaning products has incorporated the best formulas, and applies research and development to fulfill its function. As a general rule, hygiene is one of the premises to be met in any work environment. Undoubtedly, risk prevention policies and the right of workers to exercise their working hours in an environment that is as hygienic as possible, are part of the daily routine in any productive or service sector.

However, due to their nature, there are some production chains that have to safeguard extra hygiene compared to others, since this is part of their own business policy. Some examples can be given, such as the food industry, food packaging or medicine, mainly those that are intended for the ingestion of some substance by people.

For all these reasons, it is essential to provide, through expert suppliers, the best professional products for industrial cleaning, since this will entail, on the one hand, complying with hygienic-sanitary regulations and, on the other, being able to lower the price costs. However, the quality of the products should never be renounced, since this, although it may represent a small saving at first, in the long run may end up being unprofitable, since the needs will not be covered and part of the product could even be damaged. of the production chain.

These reasons are the main ones to recommend to the industrial sector that it has the absolute obligation to comply with exhaustive regulations that do not skimp when going to a good supplier, which, in its case, can help minimize costs for large consignments of purchased products.

Likewise, one of the most important industries in hygienic inspections is precisely that of food manufacturing and handling, which is why cleaning and disinfection in the food industry must be carried out under exhaustive criteria. And this can only be provided by a good chemical industry and official distributor of cleaning products. Thanks to the research and development of these companies, it is now possible to have products on the market that are increasingly natural, pleasant for the environment and that seek to eliminate all possible types of contamination.

Industrial cleanliness as a sign of guarantee

As has been observed, the food and pharmaceutical industry have to redouble their efforts in terms of hygiene. In the case of the former, this will prevent the proliferation of bacteria that can cause real health problems in the consumption chain, such as listeria or salmonellosis, both of which are highly contagious.

However, industrial cleaning, in any sector as a whole, is an added plus for the quality of the final product, even if it is not so standardized by control standards. In this sense, it should be noted that the vision of a clean factory or of any business is also part of its showcase and is a good example of the interest that management places in the overall vision of its brand.

Thus, it will not be the same to go to a mechanical workshop where the oils and the accumulation of resins and other elements are the showcase that the customer visually receives, than to go to one where everything is tidy, clean and that is perceived with a good hygiene. Without a doubt, betting on the second is going to be the option of the majority, hence the importance of maintaining any business with good cleaning standards.

The same happens with the cleaning of industrial warehouses, since it is one of the premises of occupational risk prevention, since the accumulation of substances can become dangerous. All of this may lead one to think that behind this need there is a specialist sector that, day by day, seeks greater development and research in order to put quality and environmentally sustainable products on the market.

In conclusion, hygiene is part of the consumer’s right, as well as the worker’s, in any production line, and more especially in sectors such as food. However, in any case, cleanliness will be an essential cover letter for any industry or business.

Industrial sweepers, a very efficient piece of equipment that improves the productivity of companies

When it comes to professional cleaning in large spaces, industrial sweepers are some of the most useful cleaning machines.

Its design and operation allows cleaning large areas in a very short time and very efficiently. In addition, its versatility is capable of providing a wide variety of benefits when carrying out cleaning tasks.

A cleaning tool that improves productivity in a company

Cleaning workspaces is a fundamental task in any company. The reason is that it not only offers a more pleasant and hygienic environment, as well as a more correct appearance, but it is also an aspect that contributes to productivity. With the help of industrial sweepers it is easier for companies to increase the productivity of their workplaces. This is because, on the one hand, they help keep them clean and tidy, and on the other, they make these spaces safer for staff.

Another characteristic of industrial sweepers, in addition to being highly efficient when it comes to keeping surfaces clean of dirt and dust, is that they work automatically. In fact, they can technically be described as automated cleaning platforms designed to sweep the floor and dispose of collected debris in the most efficient way.

Benefits offered by industrial sweepers

By themselves, these machines are capable of offering different benefits that go beyond just keeping the floor clean. As already mentioned, its use is capable of increasing productivity within a company by keeping spaces clean. But besides that, they also save time, sweeping any area much faster than a person.

On the other hand, industrial sweepers are agile machines, very easy to use and drive, economical considering the benefits they provide, offer a long life, and can also be used on a wide variety of surfaces. In companies like Envitec, you can find a wide range of industrial sweepers of excellent quality and of different prices and sizes, that is, for both small and large surfaces. From manual industrial sweepers, to the largest motorized ones, all are available in the stock of this company.

How to degrease mechanical parts?

The degreasing of metal components, machinery and surfaces is an essential part of a wide variety of industrial and manufacturing activities. Machines must be clean to operate efficiently. Old parts must be cleaned before repair. Items produced should be cleaned prior to finishing, packaging and shipping.

Why clean grease from parts?

The challenges of degreasing mechanical parts vary depending on where the grease accumulates: in your machines, tools and equipment, or on the products you manufacture.

While regular lubrication of parts is generally a good thing, a buildup of dirty grease on industrial equipment can reduce performance and increase the rate at which components wear. And it will increase your production cost.

The risk of grease accumulating on items during production and manufacturing is slightly different. If you don’t remove it correctly at the right points in the process, you risk causing problems in the later stages of production and finishing, especially if they involve coating and painting. Grease can also complicate quality control, whether you do it manually or automatically.

How to degrease parts effectively?

In many cases, the process followed by companies to eliminate fat is long, repetitive and very laborious:

  • Wipe off most of the grease
  • Apply detergent or solvent to dissolve grease
  • Scrub to remove accumulated grease from corners and holes in parts
  • Rinse the surface
  • Dry the parts completely to reduce the risk of rusting
  • And even if you follow this process carefully, there is a risk that the end results will vary from one cleaned part to another.

There is a better way.

Degreasing solutions

The process is similar to the dishwasher you might have in your kitchen:

  • You load dirty items into the machine
  • You select the cleaning cycle you want to run
  • You press Start

The machine cleans mechanical parts, removing grease to a standardized standard that suits you, in a predictable period of time. And while the machine is running, you can focus on other key tasks.

This approach uses modern chemical degreasing solutions that are water-based rather than flammable solvent-based, reducing both workplace hazards and environmental impact. These degreasing fluids are recycled multiple times to minimize costs and include anti-corrosion agents that prevent flash rusting when the cleaned parts dry out.

The Importance of Industrial Mold Cleaning for Productivity and Quality

In a society marked by accelerated industrialization, mass production of standardized products has become the norm.

As such, the key tools are industrial molds, which are used in many processes such as injection molding, compression molding or hot molding. This equipment has a huge impact on the quality and efficiency of production and careful and constant maintenance becomes necessary.

What is an industrial mold?

Industrial molds are tools for giving a precise shape (intermediate or final) to the part or material to be machined, by inserting it in plastic, molten or solid form inside 2 half-molds, the one fixed and the other mobile, in order to determine the shape to be obtained.

Generally made of steel, but also aluminum for prototyping activities, industrial molds have a lifespan that can range from a few parts (even just one) to hundreds of thousands of parts.

When a mold is destined to shape thousands of pieces, constant maintenance over time becomes a fundamental activity in order to guarantee the best production quality, avoid sudden production stoppages and ensure the durability of the mould.

The real cost of an industrial mold

An unmaintained industrial mold can generate major costs for a company: costs related to the downtime necessary to carry out maintenance and repair operations (often carried out by mold makers outside the organization), costs generated by the subsequent restart of production and consequent regulation, loss of profits caused by non-optimized production, an increase in the number of nonconforming batches due to poor quality or even, costs arising from the degradation of the long-term corporate image.

Preventive maintenance then becomes a strategic operation for companies and must be favored within the framework of dedicated processes, scheduled regularly. This need becomes even more frequent in the case of aluminum molds or complex relief molds that wear out more easily. The temperature, type of material and the pressure it is subjected to when inserted into the mold can also impact the frequency of maintenance activities.

The correct use of a mold will limit the need for inspection and revision operations, but will not completely exclude them.

And as with any maintenance process, cleaning is a crucial step.

The industrial mold cleaning process

In order to carry out maintenance, the mold must first be dismantled and checked before moving on to the cleaning phase: parts with a higher concentration of dirt or parts with cracks (cracks) must be cleaned. further control to identify defects in the mold to be rectified.

At this point, it is possible to move on to washing operations to remove different types of residue, including:

  • the release agents used to facilitate the extraction of the parts produced, the residues of lubricating oils and the traces left by the gases generated by the contact between the plastic material in the fluid state and the mold at high temperature, which contain residues that soil the mold itself;
  • oils used in the cold forging of metals;
  • residues of soft metals and lubricating oils used to avoid “tearing” in cutting and thus obtain clean cuts;
  • graphite greases used as a mold release agent in the hot stamping of metals.

The cleaning activity must be carried out avoiding damage to the mould; operations such as sandblasting, shot-blasting or the use of aggressive and potentially corrosive products such as caustic soda should therefore be eliminated.

Moreover, reliance on manual washing processes with rags and solvents leads to unsatisfactory levels of cleaning, especially in the case of molds with complex geometries and small figures.

Considering the considerable impact of an industrial mold on the quality of a mass production, it is advisable to carry out a standardized washing always using the same products and methods in order to minimize the possible variability of the characteristics of the production parts.

So how do you get the desired result? With automatic parts washers that use standardized processes and laundry detergents to thoroughly clean parts for flawless results.

Everything about the right tanker cleaning

Large quantities of animal feed, chemicals, mineral oils and foodstuffs are often transported in tank trucks. Careful cleaning of the tanker truck is required at regular intervals and when the goods to be transported are changed. Only under this condition will the goods reach the recipient safely and in the right quality. Read here what needs to be considered when cleaning tankers.

What is the standard for tanker cleaning?

Tankers are trucks or trailers that can transport free-flowing, liquid or gaseous substances in a built-in tank. Some of them are equipped with hoses and pumps or blowers that are used for emptying. There is a uniform standard for tanker cleaning in Europe that was developed by the EFTCO (European Federation of Tank Cleaning Organisations). In Germany, the DVTI (Deutscher Verband für Tankinnenreinigung e.V.) represents the interests of companies that operate stationary tank interior cleaning systems. There are similar organizations in the other EU countries. In the Netherlands, for example, ATCN (Association of Tank Cleaning Companies Netherlands) takes on the tasks. The aim of the standard is to ensure quality, environmental and health protection as well as occupational safety during cleaning work.

What is the ECD cleaning certificate?

Companies that have been proven to use the standard use a uniform cleaning certificate known as the ECD (European Cleaning Document). The advantage of the ECD is that EFTCO tank cleaning codes are used for all information. In this way, the content is comprehensible for everyone involved, regardless of the exhibitor’s language. Permission is required to issue the certificate. This is granted by the DVTI when the cleaning facility is registered and meets all the regulations and conditions of the EFTCO.

How are the EFTCO tank cleaning codes structured?

The EFTCO tank truck cleaning codes consist of one letter and two digits.

The letters have the following meaning:

  • C (Cleaning agents) – cleaning agents

Examples: C01 alkaline cleaning agent, C10 neutral cleaning agent, C20 acidic cleaning agent, C30 caustic soda,

  • E (Extras) – additional work

Examples: E01 entry into the tank, E03 passivation, E04 repair, E15 cleaning with a fuel nozzle, E35 hot air drying, E90 sealing, E95 exterior cleaning

  • F (Foodstuffs) – Foodstuffs

Examples: F01 cleaning with drinking water only, F50 food-approved cleaner, F85 disinfection with hydrogen peroxide, F98 food-approved cleaning system

  • H (Handlings) – Equipment movements

Examples: H01 put on, H50 put down

  • P (Procedures) – Procedures

Examples: P01 cold rinsing, P02 hot rinsing with temperature above 80 °C, P21 rinsing, P30 drying, P60 nitrogen rinsing

  • T (Tests) – Checks

Examples: T01 visual and odor control, T41 conductivity test, T42 ATP test, T43 pH value measurement, T60 lower explosive limit test, T61 oxygen measurement, T90 vacuum test

  • W (Waste) – Waste

Examples: W01 waste product, W50 waste water treatment, W90 pre-cleaning

The EFTCO codes are listed on both the order forms and the cleaning certificates. In the case of orders, they help to clearly record the requirements. Proper execution of the tanker cleaning is documented in the certificates.

How is compliance with the conditions and regulations checked?

An SQAS (Safety & Quality Assessment System) is used to check compliance with the conditions and regulations. The basis is a detailed, standardized questionnaire that is filled out by the applicant and evaluated by independent experts.

The individual questions about cleaning the inside and outside of a tanker relate to:

  • the specification of the technical equipment of the cleaning system (construction, inspection, maintenance and repair, calibration of measuring and testing devices…)
  • the work processes of the facility (existence of appropriate work and process instructions, enforcement of occupational safety, use of qualified specialist personnel, monitoring of emissions, responsibility of the driver…)
  • order processing (existence of a proper cleaning order, incoming inspection, selection and implementation of the appropriate cleaning process, final inspection, preparation of the cleaning certificate…)
  • administration (creation and storage of documents, provision of cleaning agents…)
  • special activities (tank heating, tank repair, transfer between road, rail, waterway or sea…)
  • the condition of the business premises (buildings, business premises, stationary facilities, tank cleaning, external washing, stationary storage tanks, waste management)
  • special guidelines for food and feed (suitable cleaning agents, hygiene, avoidance of cross-contamination, securing of valves and openings after tanker cleaning with seals…)

How does the tanker interior cleaning work?

Sophisticated technology for cleaning the inside of tankers is available in modern cleaning systems.

This includes:

  • suction systems for liquids and gases
  • high pressure pumps
  • hot water and steam generator
  • tanks with detergents and disinfectants
  • tank washing heads
  • blower for drying the interior
  • measuring and testing devices
  • waste water and exhaust air treatment

This equipment makes entering the tanks superfluous in most cases. If it is nevertheless necessary, special safety measures apply to protect employees from slipping and falling, from released aerosols, hazardous substances and detached product residues as well as from lack of oxygen.

Incoming inspection and selection of the cleaning process

With the order for the tanker cleaning, the operator of the cleaning system receives the necessary information about the vehicle, the last load, the required scope of cleaning and the required checks of the cleaning result. The cleaning process, the use of special cleaning, rinsing and disinfecting agents and the safety measures to be taken depend on these facts. Therefore, the cleaning company must carefully check whether the information corresponds to the facts found.

Preferred cleaning processes use cold water, hot water or steam to clean the inside of tankers. If these media are not sufficient, special cleaning agents must be used. On the one hand, the cleaning agents used must be effective and, on the other hand, they must be compatible with the dirt. A wrong agent can trigger unexpected chemical reactions with charge residues. With the almost unlimited number of possible loads in tankers, selecting the right cleaning agent is a challenge.

Transportation of chemicals in the chemical industry

Truck tanker chemical delivery tanker cleaning

Customers who are familiar with the cargo can give hints. The manufacturers of agents for tanker cleaning should be listed service providers at the DVTI and offer well-founded advice. Kluthe is also a member of the ATCN. Kluthe’s product range includes solutions for all problems that arise when cleaning tank trucks.

This includes funds for:

  • the interior cleaning with food approval
  • the outside cleaning
  • the removal of latex residues
  • the removal of resins
  • the removal of labels and security labels
  • final check

The effectiveness of tanker cleaning must be proven by tests. The minimum scope includes the visual and odor control on the dome of the tank. Further checks are required for tankers used for transporting chemicals or foodstuffs. This includes, for example, the ATP test. ATP is the abbreviation of adenosine triphosphate. This substance provides energy metabolism in all living cells. If no ATP is detectable, no microorganisms have remained on the inside walls of the tank.

Upholstery and carpet cleaning with injection and extraction vacuum cleaners

Cleaning upholstery or carpets is usually a delicate task and we recommend always leaving it in the hands of professionals. Not using the right product and method on textile fibers depending on their nature or type of dirt can cause us to even permanently damage the surface. or colour.

Today we can find hundreds of dry cleaning products, foams and endless techniques and home methods on the internet, but in most cases it is necessary to clean with a wet system to clean and disinfect properly, we insist depending on the type of material.

We can find 2 processes to carry out wet cleaning professionally, a manual process indicated especially for synthetic upholstery or fabrics protected with anti-absorbent treatments and a mechanical process, in which we are going to delve a little deeper in this post, which has results. deep hygiene and disinfected and is indicated for upholstery and carpets with absorbent textile fibers.

To carry out this mechanical process of wet cleaning for upholstery and carpets, it is necessary to use professional machinery, in this case injection and extraction vacuum cleaners, capable of introducing or injecting cleaning and extra-disinfecting products into the fabrics or absorbing the same time dirt and dry the surface. Although it may seem like a process similar to using soapy water and a cloth, the result in the case of cleaning with injection and extraction equipment is much deeper and visible almost immediately.

How do injection and extraction aspirators work?

The operation of these machines, despite being for professional use, is quite intuitive.

They can be used as vacuum cleaners for solids or liquids, they normally have a polyester filter, a clean water tank in which the detergent or chemical product that is necessary for cleaning and another dirty water tank are also deposited.

When the clean water tank is filled and mixed with the right product, we have a small suction hose connected to a pump that will absorb the mixture, to be injected through the hose on the surface of the upholstery or carpet, At the same time, dirt and injected liquid are absorbed and dragged away, this also does a drying job, although the reality is that it will always be necessary to dry after washing or let it dry naturally.
