During the Auto spraying and painting process, the paint mist and organic waste gas are mainly polluted, and the paint is atomized into particles under the action of high pressure. When spraying, some of the paint does not reach the surface of the paint, and the airflow is dispersed in the air to form a paint mist; the organic waste gas is diluted. The volatilization of the agent, the organic solvent will not adhere to the surface of the paint with the paint, and will be completely released into the organic waste gas during the painting and curing process (there are hundreds of volatile organic compounds reported in the literature, belonging to alkanes, cycloalkanes, olefins, aromatics, respectively). Compounds, alcohols, aldehydes, esters, ethers and their compounds). The composition of spray paint and paint exhaust is mainly: “triphenyl” and volatile organic waste gas (VOCs) treatment.

The exhaust gas in the paint baking industry has a large amount of exhaust gas, a high concentration, and contains many kinds of organic substances. Generally, the exhaust gas of the paint industry contains organic substances such as triphenyl, alcohols, ketones, ethers, esters and the like. The exhaust gas in the paint baking industry contains many kinds of organic substances, among which the content of “triphenyl” is high and the damage is high. The benzene, toluene and xylene are colorless, have aromatic odor, and have a boiling point of 80 degrees. They are volatile organic compounds. They all have volatile and flammable properties. If it is directly discharged, it will pollute the air environment in life, and if it is not handled properly, it will easily cause fire. Therefore, it is recommended to equip the paint baking equipment with environmental protection equipment to treat the exhaust gas discharged and discharge it after meeting environmental safety standards. GL Paint Booth is an expert in exhaust gas treatment for professional baking rooms and spray paints. It has professional baking room and environmental protection equipment production and exhaust gas handling solutions.

In the 2017 GL Spray booth factory got more paint booths and car lifts orders, especially the Truck Spray Booth and Personal Man lift, so we did hire more Staffs at the beginning of 2018.

Now we have more than 60 news colleagues to join GL spray booth family and our Boss did a three days training for them.

First they are in the meeting room and view the PPT of Spray booth, so that they can know that what is the spray booth and car lifts.

Then all staffs go to the show room to view the Spray booth, to see the real one. At the same time we have skilled staff to introduce the spray booth and help them be familiar.

Prepare and adjust Spray gun

Spray guns and related equipment should be clean and in normal working order prior to spray application. Check that the spray gun produces the desired spray pattern. The ideal spray shape should be symmetrical with uniform spray particle size distribution and sharp edges with only a small amount of paint mist outside the edge of the spray shape. Low atomization pressure helps produce a correct and uniform spray pattern, reducing bounce and overspray.

Hold Gun correctly

Properly sprayed tracks are perpendicular to the work piece surface. Spraying according to be coated surface angle, the distance between the spray gun and the spray surface is generally 15 ~ 30cm. To get wetter, darker-colored and thicker coatings closer to each other; to get drier, lighter and thinner coatings, the distance can be further.

Walk the gun

Guns include the spray gun on the surface being coated and the speed of the gun. Spray gun should be kept at right angles to the surface being coated, parallel operation. Gun speed is generally 30 ~ 60cm / s between the adjustment, and requires constant. If the spray gun is inclined and arc-shaped operation or changing speed, you can not get a uniform thickness of the film, and easy to produce stripes and marks; spray gun operating speed is too slow (30cm / s below), then easy to produce sagging . Adjacent spraying trip should have a lap, that coincidence rate, coincidence rate should reach 50% -60%. Too fast or lap when not easy to get a smooth film. When the uniformity of paint thickness requirements, should be used the cross-spray method, then do horizontal spraying.

New car hand, the most vulnerable is the paint. Careless car wash, paint will be injured. In fact, there is damage to the paint even when it is loaded on the production line. Small general abrasions, paint surface scars, scars whiten. That is the surface of the paint was shaved. There is no need to paint Light, beat with sand wax or wax several times. Heavy, polished it.

Seriously, you can see the color of the primer (often, the primer is dark). Well, please take a look at the wounds. In general, the bumper, rearview mirrors and some car wheel eyebrow these parts are plastic or stainless. Ugly is not a big problem. It does not matter to fill up the paint down. Others, it is necessary to fill the paint, otherwise, even if it is a small damage, the steel will begin to rust, you can grind the rust with a grinder, then epoxy primer (rust), and then scraping Tu putty

In the paint, there are various solvents containing benzene and benzene compounds, such as toluene, xylene and so on. Diluents in ethanol, butanol and other common industrial solvents are also toxic, and even some are highly toxic, such as methanol and so on. The existence of these toxic substances on the human nervous system, respiratory system and skin have some toxicity, the most common occurrences such as benzene poisoning and paint poisoning and so on. In the coating process, often produce large amounts of volatile gases, spread in the air. These large amounts of toxic hot gases, if inhaled by the body, can develop nervous system diseases, such as dizziness, palpitation and nausea and vomiting. Frequent exposure of fingers and other parts to various solvents and toxic gases can also cause skin corrosion, degreasing, itching, roughness, cracking and other diseases.

In painted environments, working eight hours a day, while working in a safe environment, does not have the same level of sensitivity and affordability. Over time, over time, it is inevitable that the body will not be affected, so in the paint job site, we must take the necessary protective measures can be considered from the following aspects.

First, establish the first thought of safety and enhance the concept of protection

Painting construction, we must establish the first security concept, enhance the concept of protection, the implementation of specific security measures. First of all should understand the types and characteristics of paint, toxic injury to the human body, the use of paint precautions, and may be poisoning emergency measures. Especially in indoor, cabin, underground construction sites, mines, vehicles and other poor ventilation or no ventilation in the construction environment, must not exceed the maximum allowable concentration of solvent and working hours limit.

Construction workers must understand in advance to grasp the packaging of toxic solvents signs, and master the safe use of solvents. In particular, the person in charge of construction and the personnel responsible for safety must establish a clear job responsibility system, supervise and inspect the implementation of safety production and labor protection regulations and relevant operating procedures. The construction methods, the issuance and use of labor protection supplies, ventilation and ventilation equipment, the normal operation of the necessary supervision, and construction workers often safety education, firmly establish the idea of safety first and labor protection concept, the timely elimination of all kinds of Safety risks to ensure safe production.

Second, to ensure the normal operation of construction equipment and safety protection devices

In the coating construction process, the correct construction technology, normal and intact construction equipment and safety protection devices, is the fundamental guarantee of safety, indispensable, is a complete system engineering.

In the rapid development of science and technology today, everyone attaches importance to the safe production of modern, general coating production site, the conditions are better. However, in some maintenance enterprises, some township and village enterprises are in poor conditions and often have one or the other problems. This is a weak link that deserves our attention. from the process, from the construction equipment and safety devices. to eliminate unsafe hidden dangers. According to the coating production of the specific circumstances, consider the use of paint construction equipment and safety protection device configuration and use. Such as indoor construction and the use of volatile solvents, should be used to install airtight equipment or exhaust devices to prevent leakage of equipment. If in the tank, tank painting inside, be sure to ensure that the displacement and intake air to maintain balance. In short, should be necessary construction equipment and safety protection device to ensure the safety of coating production.

Third, improve the construction environment, to ensure normal ventilation

For spraying construction sites, normal ventilation is very important, is to prevent the occurrence of fire and explosion accidents of the fundamental measures, but also to prevent harmful gases an important means of excessive. Under normal circumstances, the windows and other openings directly with the outside ventilation area of ?? the area should be coated workshop floor area of 1/20 or more, it is possible for normal ventilation. If you have good ventilation equipment, you can not be limited by the above ratio. The actual situation of coating production, paint usage and types are constantly changing, volatile gas production and discharge are not balanced, all with the time, the region, the spraying situation without certain changes in law. To this end, we must constantly carry out the necessary testing, strictly control the "three wastes" exceeded, identify problems and solve them in time, must never have the idea of once and for all.

Fourth, to strengthen the construction environment testing to prevent "three wastes" exceeded

Indoor construction, at least check the air concentration in order to maintain a good construction environment every six months. This is in the production of more normal production without any difference between the circumstances put forward. For coating production changes, such as production, process have greater changes, we must important parts, that is, the safety factor of the larger parts, timely testing. Grasp the changes in the status of various parts of the data in order to take appropriate measures. For widely used organic solvents, such as acetone, xylene, toluene, ethyl acetate, dichloroethane, etc. must regularly check the degree of contamination and determine the sampling site. The main choice in the exhaust, exhaust vents, floors, ceiling and other parts of the vicinity, and determine the concentration distribution, and the choice of the same interval between the plane as the measuring point. According to the measured data and distribution, check with the control standards. If there are excessive standards, measures should be taken to deal with them to prevent accidents and ensure a good and safe environment for construction.

Fifth, the operator's protection

In the coating process, the operator in the construction site, directly in the paint and solvent operation, all kinds of toxic gases and solvents pervade, filled the entire place. Therefore, the protection of individual operators is very necessary, but also very necessary. This is also an important part of painting safety technology.

Construction workers in the painting operate, should wear a variety of protective equipment, such as overalls, gloves, masks, masks, glasses and shoes and hats. Do not allow solvents to touch the skin. At the same time rub the exposed skin on medical Vaseline or other skin care products. Low boiling point on the solvent, volatile fast, toxic, easy to inhalation of the trachea spraying workplace should pay special attention to prevent inhalation of the lungs.

Toxic gas emitted during construction, at high concentrations, on the human nerve has a serious stimulus and harm, can cause cramps, dizziness, coma, pupil enlargement and other symptoms. If not timely protection, in prolonged exposure can make loss of appetite, damage to the hematopoietic system, chronic poisoning.

Paint mist for the human body can not only inhale through the lungs, but also through the skin and stomach absorption and the occurrence of hazardous effects. Long-term contact with the human body paint surface, can dissolve the skin surface fat, causing dry skin, cracking, redness and may cause skin diseases.

Some paint pigments contain toxic components, such as red lead, lead chrome yellow, etc., this paint brushing, it is best not to spray. When used, should take precautionary measures, this paint can cause acute or chronic lead poisoning, the best alternative alternative coating to reduce the possibility of poisoning.

Spraying paint booth, do not immediately stop the ventilation equipment, let continue to run for a period of time, the residual paint mist and solvent gas emissions.

After painting, the operator felt tracheal dryness, due to inhalation of paint mist due to solvent evaporation, should drink warm water. When cleaning spray guns and tools, not to touch the skin with solvent. After finishing wipe the skin on the Vaseline or other skin care products, then wash hands and feet with warm water and soap, it is best to often take a shower.

Do a regular basis the coating operator physical examination. the operator of the poisoning situation, in a timely manner to give the appropriate medical treatment.

Spraying waterworks Hardware flow refers to the hardware, the special shop to carry out large-scale transformation of the spray shop, installation of rails and the special design of the barn and primer room formed after the flow of water forms. Hardware running water is a kind of large investment and effective water flow method. It is suitable for large-scale blow-molding workshops. The implementation of hardware water flow has high requirements for plant and investment, and the vehicles on the ground track are vertical or horizontal rows. The paint shop must be 30-80 meters long to accommodate the entire line. In addition, due to the need to increase the ground rails, the conversion or addition of barns, primer rooms, so the overall investment will be quite large. Since the hardware flow is mostly a straight line that leads to the end, it generally adopts a beat-type connection. Generally divided into demolition parts - sheet metal - putty - sanding / shading - finish - baking - polishing - installation of parts and other processes, each process time is fixed and equal, this time is called Beats, such as 1 hour. Only in this way can the advantages of the hardware flow in the assembly line be as follows: Compared with the traditional squeezing spray shop, the efficiency is greatly improved; the equipment is excellent; the employees have a good operating environment; the tempo is fixed so that it is convenient to manage; the vehicle is parked on the rail car The technicians push forward, so under normal circumstances, the vehicle does not need to be started from the beginning to the end. On the other hand, hardware running water has its shortcomings, which include: First, large investment and high demand for factory buildings; Second, the time for each beat is difficult to determine, and in most cases, the time of the beats is what people come up with out of nowhere; Third, the lack of flexibility, because as long as the time of each beat a fixed, in theory, you can calculate how many cars out of every day. However, it is difficult for special shops to ensure that there are such fixed vehicles every day. This will affect the flow of hardware water. This can easily lead to flaws in the assembly line. It is up to the workshop managers to dispatch and coordinate with high skill.

Spray waterworks Process flow refers to the division of flow patterns in different functional areas in a blow room spray shop. According to the time-consuming degree of each process, how much their workstations occupy is different. The most time-consuming process of painting is the “putty-ashing” and “primer/grinding” processes, so the number of stations assigned to them is relatively large. Moreover, because the entire flow of water is not strictly a "straight line", the use of "non-beating flow" forms is more often used in the cohesion mode. Therefore, there are no strict time limits for each process.

Its disadvantages are: Because the connection time between each process is completely "fuzzy", it is necessary to have a competent manager who knows how to manage this line, otherwise it may cause inefficiency.

Spray production line process

1. Sheet metal correction: First, technicians at the sheet metal correction station will put the cleaned vehicles on the track assembly line. After the calibration and disassembly work has been completed, the vehicle will move along the track to the scraping station.

2, squeegee (scratch putty): scrubbing workers to check the quality of sheet metal correction, the workpiece surface after processing to scrape gray, you can choose natural drying or infrared baking, after the completion of the vehicle to the polishing operation station

3, grinding operations, grinding personnel according to the needs of the process to select the appropriate sandpaper and grinding tools, the operation, the job is completed and moved to the next paint station

4. Primer: After the primer technician checks the quality of soil and sanding, it performs primer spraying, secondary polishing, etc. After the completion, the vehicle moves to the shelter station along the track.

5. Masking: The masking station technician checks the quality of the primer and masks the non-sprayed surface, and cleans all the gaps with compressed air. After the masking is completed, the vehicle moves along the track to the painting booth.

6, spray paint: paint technicians check the quality of cover, clean, spray, after the completion of the vehicle was moved to the paint room,

7. Baking: The paint operator shall set according to the time and temperature required for the paint, turn on the power and monitor the work of the equipment. The sound of the paint is complete with sound and light alarm, and the vehicle will be cooled and launched.

8. Polishing: After the polishing technician checks the paint quality, the wax type is selected according to the size and size of the surface of the vehicle, and the polishing and cleaning operations are completed. After the completion, the vehicle is moved to the assembly station.

9. Assembling: Assembling technicians will completely disassemble the disassembled parts and complete the repair work. The spray water line has improved the ability to repair paint vehicles by 35%, the overtime time of technicians has been reduced by 90%, and the cycle of vehicle owners' refinish paint has been shortened. 50%.

Spraying waterworks is an extension of lean production methods from automobile manufacturing to vehicle maintenance. It refers to the re-planning of the squeezing spray shop, the use of specific methods to transform the workshop into different functional areas, and the specific working methods are performed by specific operators. Because the different processes of the vehicle to be repaired are performed in different areas and by different mechanics, it is similar in form to the “assembly line” of the automobile production plant and is therefore called “flowing operation”. According to its implementation form, it can be divided into hardware flow and process flow. According to the connection method of each process, it can be divided into non-beat flow and rhythm flow. The traditional refinish process is one-to two-person repairs. A repair process consists of more than 10 process steps. The spray line is a reasonable process for the paint repair process. The equipment and personnel are divided according to the process flow. Thus, a complex matter is simplified, and a complete refinish paint process is generally divided into 7-9 workstations (sheet metal, squeegee, sanding, primer, cover, finish, drying, throwing, Assembly,), each according to their own circumstances, the flexibility to choose the number of workstations hardware flow The construction time of each workstation is almost similar, each workstation according to the workload of each repair vehicle to adjust personnel, respectively, responsible for the work of different processes, To ensure that each station has similar working hours, just like the assembly line of a car assembly, the working time of technicians at each workstation is strictly controlled to ensure that the vehicles are completed according to the planned time, and the maintenance quality of each workstation is also strictly controlled. After the completion of the maintenance of quality, all the cars were completed in accordance with the expected time. Let's explain one by one:

When most of repair shop or vehicle warehouse buy auto paint booth, they usually will choose some other parts for them paint booth.

Such as below:

1. Safety Thermostat

The safety thermostat(shown in Fig.1.10), placed in the generator group near to the heat exchanger, switches off the electric system if the air flow reaches a temperature superior to 90°C

2. Anti-vibration Joint  

The anti-vibration joint (shown in Fig.1.11), placed between the generator groups, and exhaust air unit with active charcoals and the spray booth, is necessary to isolate the vibrations produced by the motor and the fan. The joint is formed by two edges of zinced plate connected by a belt of PVC that by contorting does not transmit the vibrations to the work environment.

3. Active carbon system

The exhausting air device have active charcoals, which the air from the paint booth environment and to decrease the percentage of polluting agents. It is composed of:

Metal frame, there rock in the panel which can keep the temperature Filtration group, composed of seven layer of active charcoal which remove the solvent fumes (purification plant).

When the Auto Paint booth working, It will have many paint mist, in order to protect the environment. We have to recycling paint mist, it can be divided into two parts:

First, when spraying the workpiece in the paint booth, the paint mist collides with the water curtain, and the water curtain dissolves into the paint mist and falls into the water tank;

Second, the paint mist that has not dissolved into the water curtain enters the water washing chamber through the gap at the bottom of the water curtain plate, and is fully mixed with the water mist sprayed from the atomizing nozzle, and the gas and water are separated and settled into the water tank. A paint mist coagulant is periodically added to the water tank to form a paint residue.

The design editor Key points

1. Determine a reasonable configuration form.

2. Determine the reasonable average flow rate of the horizontal plane air in the spray booth.

3. The air supply and exhaust system are reasonably matched to ensure a slight positive pressure in the painting room.

4. The thickness of the water curtain should be uniform. Pay attention to the structure of the water tank and the distribution of the water supply pipeline.

5. The distance from the lower part of the water curtain board to the liquid level of the water tank should be reasonable.

6. Washing atomizing nozzles and pipelines should be easy to disassemble, replace and clean.

7. Separation of gas and water should be sufficient and easy to clean.
