Automotive Spray Booth

Date: 2016-06-04
Browsing times: 69

When painting, the external air filter after primary filter by the fan to the roof, then the top of the filter after filter purification into the second room. Room with full air-style down to 0.2-0.3m / s speed of downward mobility, so after painting the mist particles can not stay in the air, and the air is discharged directly outside the room through the bottom out.

 

working principle:

When the paint, the paint was adjusted throttle position, hot air circulation, baking room temperature rapidly rises to a predetermined drying temperature (55 ℃ -60 ℃). After the external fan fresh air filter First, after the heat exchange chamber to the paint room at the top of the thermal energy converter occurs, and then after the second filtration and purification, hot air circulating through the throttle effect, in addition to a small amount of fresh air sucked into the outer , most of the hot air has been heating continued use, so paint the room temperature gradually increased. When the temperature reaches the set temperature, the burner automatically stop; when the temperature drops to the set temperature, the fan and the burner and open automatically, so paint the room temperature is kept relatively constant. Finally, when the baking time to reach the set time, the paint room automatically shut down, the end of baking.

 

classification:

1, depending on the size: Standard, heterosexual

2, depending on the configuration: ordinary type, luxury

3. The heating: fuel type, far infrared

 

Overview:

Automotive Spray Booth is generally used to spray and bake the paint, used to call "car paint room.

Spray Booth, the name suggests is in a room on the filtration painting objects painting, also called the paint room. Traditional painting in the open air with a nozzle to the appliance (cars, furniture, etc.) painting, but this way will reduce the quality of the painting is for large appliances, such as: painting process will dust in the air are mixed in the paint in order to reduce paint quality; uncertainties waste paint and painting area will be very dirty; the staff, the dirty one hand, on the other hand will be inhalation of paint mist detrimental to the body. Later, people want to paint set within a certain range, it gave rise to the earliest painting room ---- ventilation painting style room, painting room in China was first in the 1990s in Chengdu generated.

Principle of air (outdoor air) - Paint the door filter cloth - painting station - use spray equipment to spray paint - exhaust fan (exhaust generated mist) spray booth this weakness still exist:

1. filter cloth easy to scratch, dust, easy access

2. Easy outdoor air into the unclean

3. not environmentally friendly, waste paint

4. The need for frequent cleaning regularly to remove dirt on the filter cloth

He had come out of the new painting room ----- total pressure type spray booth, has been widely used in China's furniture industry. Full-pressure spray booth ventilation on the basis of principles and painting room style is the same, but with the pressure of orientation, using the pressure taken off from the vertical painting, painting making more precise. Also in terms of hardware, there are computer room, the "multi-layer cotton filter" instead of filter cloth, clean air and high; the use of an infrared heat lamp, save drying time; when the discharge excess mist, curtain use more environmentally friendly. Thus, rework probability is almost zero, but also saves paint, improve work efficiency. Because the use of an infrared heat lamp, so people also called the paint room.

 

background analysis:

In the case of many of the world auto market consecutive losses, the Chinese auto market has become the brightest spot, created a brilliant performance, which gives the development of China's motor insurance market provides a big stage. Throughout the past decade China motor insurance market, although the big waves and storms, rise and acceleration, but all of them on their own, enterprises, Chinese motor insurance market is full of enthusiasm and confidence. With the continuous increase of the total domestic car and continue to develop over the entire size of the spray booth, the spray booth needs, not only in the growing demand for large-shaped spray booth regard, and good quality, demanding special type Booth accounted for a larger market share in a growing market share. There are people in the industry at the show description, high corporate income employees, but still complained: the money but no time to spend. Great painting shaped housing market "crazy", special type of paint spray booths also "fire", ordinary type paint spray booths to sell more "bull" the. At the same time, the market opportunities for manufacturers by means of large-scale development began to re-plan their own development and positioning, increased attention to all aspects of the paint room.

 

Structural principle:

Automotive Spray Booth principle and structure: The entire spray booth for the assembled structure, housing body with picture-pluggable insulation spray wall, good sealing, insulation properties, aluminum edging the door, the door is equipped with a central observation window always observe the dynamic room; rooms equipped with body side door work, facilitate staff access, high-quality stainless steel heat exchanger, heat transfer efficiency, long service life; selection of imported cotton filters, low-noise high air volume fan, ensures perfect painting effects sex. Spray painting room workpiece provided: (1) clean working environment; (2) the full collection of mist. Spray booth configuration according to the workpiece size, shape, weight and production program may have a variety of methods: open, closed points; there are continuous, intermittent points; workpiece rotation or fixed points; unilateral spraying and bilateral spraying points. And the development of the oil curtain spray booth, under the painting room. The structure should include: air filtration system, the workpiece hanging (transport, rotation) means curtain system, water system, exhaust system, sink, lighting fixtures and chamber body.

 

Mist recovery principle:

Mist recovery can be divided into two parts: First, spray workpiece, impingement mixing Mist and curtain, the curtain will fall into the mist partially dissolved in the water tank; the second is not integrated into the curtain of mist through the bottom of the water curtain slot into the water chamber, flows into the sink after thoroughly mixed with water mist spray nozzle, the gas-water separator to settle. In the sink periodically added to the formation of mist coagulant paint residue.

 

Performance:

Several later Booth measure factors:

① brightness, paint the room brightness required to achieve 800-1000 lux, but requires the use of near-D65 light source lighting, and room wall should be matte white;

② air flow;

③ filter effects, depending on the type of cotton roof paint, has a general repair shop used EU5 and EU6 two models can be when using paint room in the room with an upper sun light exposure is usually very fine dust per square meter should less than 5;

④ wall sealing effect, paint room must be sealed at the seams and there should be no accumulation of paint dust;

⑤ ensure positive pressure, air flow into the paint room should be slightly larger than the amount of wind, so paint room kept at a positive pressure;

⑥ sealing effect heating systems, burner and chimney should be sealed around good, putty combustion can not occur;

⑦ heating rate, paint rooms rose from 20 ℃ 60 ℃ used for about l0-l5min, should also be aware that some are not allowed to paint room thermometer, the temperature of the room you want to paint the metal body to prevail when the measured temperature. If the selected paint room can meet the above criteria, it may well be an ideal paint room. However, the cumulative use of the process, there will be poor quality paint room, dusty room, the effect of poor construction, poor lighting and other conditions, in fact, as long as we can paint the proper use and maintenance, these problems It is completely avoidable, following a brief car paint room under Cautions and routine maintenance skills, hoping to reduce unnecessary losses and reduce security risks.

3, air supply, exhaust system, a reasonable match to ensure indoor painting slightly positive.

4, the curtain thickness should be uniform, should pay attention to structure and distribution of water supply line on the tank.

5, the lower the water curtain from the tank to the level should be reasonable.

6, water spray nozzles and pipes should be easy to remove, replace and clean up.

7, the gas-water separation settlement should be fully and easy to clean.

 

Main Category:

Automotive paint spray paint room usually used to bake paint and, therefore, the most accurate description of the paint room should be "Booth" is widely used in the surface paint cars, machinery, hardware, furniture, chemical and other industries, paint job. To paint room air flow direction can be divided into the following three categories: cross-flow spray booth; Booth-style punch down side; the whole down-stroke paint room.

Red paint at the side of the room type: air into the paint room ceiling by means of filtration, is discharged from the side of the wall of the room. This is a mid-priced paint room. Since the mist away from the body, and can be removed from around the operator's mist, thus the effect of painting and working conditions than those ideals.

Automobile paint room, furniture painting rooms, green spray paint room. Booth green spray paint room, which includes a spray booth and paint rooms, its features are: top spray booth and paint rooms equipped with inlet channel and air distribution plate, the bottom of the spray booth with a circulating pool with the circulating pool of iron grid to grid, recycling pool side and connected to the exhaust passage. It solves the problem of existing products exist poor working environment, leading to the paint quality is not high, but also a serious painter of physical and environmental damage, the utility room has a new environmentally friendly painting efficient, environmentally friendly, energy-saving advantages.

 

Operating essentials:

When painting, the external air filter after primary filter by the fan to the roof, then the top of the filter after filter purification into the second room. Room with full air-style down to speed ≥0.3m / s flow downward, so that can not stay in the air mist particles after painting, directly after the filter device through the bottom, from the air is discharged outside the room. Make sure the room is not to spray paint the room dust leakage, contamination of the workpiece surface to ensure maximum quality paint. When the paint, the paint was adjusted throttle position, hot air circulation, baking room temperature rapidly rises to a predetermined drying temperature (≤80 ℃).

 

classification:

1, the air flow direction is divided into three categories:

Cross-flow spray booth;

Side down-stroke painting rooms:

Air into the spray booth through the ceiling filter means is discharged from the side of the wall of the room. This is a mid-priced painting room. Since the mist away from the object itself, the body, and can be removed from around the operator's mist, thus the effect of painting and working conditions than those ideals.

All in red spray paint room;

2, heating Category:

Can be divided into diesel painting rooms, painting rooms electric heating, steam heating paint room, infrared paint room, waste oil painting rooms and so on.

3, mist treatment Category:

It can be divided into dry and wet spray booth spray booth (water) into two categories.

Normal use of the spray booth to use the most is a dry process, the filter system (mainly refers to primary and secondary filter cotton filter cotton, etc.) should be regularly checked and replaced, otherwise ranging from the impact of the quality of the paint, it may cause heavy fire. With the further development of science and technology to deal with the excess paint mist way more advanced. Many high-end cars use water spray booth, the excess dissolved in water mist treated in the manner mist has made considerable progress.

 

Three key draft-type spray booth is:

1. Ventilation ---- ventilation key style spray booth work

2. Filter ---- air filtration of small particles

3. The exhaust ---- waste air and fresh air into the exhaust

 

Precautions:

1. Before spraying must check the spray pressure is normal, while ensuring that the filtration system clean;

2, check the air compressor and the oil-water separator dust, so paint hose to keep clean.

3, spray gun, hose, and spray paint cans to be stored in a clean place;

4, except that a hair gun and sticky dust cloth, the other steps before spraying all should be done outside the paint room;

5, only the paint room spraying and baking step, and paint the door can be opened only when the vehicle is out, the air circulation system must start spraying when you open the door to a positive pressure to ensure that the dust can not be outside the room enter the room;

6, must wear the specified clothing and wearing paint safety equipment to enter the paint room to operate;

7, during the baking operation, you must paint the room to come up with flammable liquids outside the room;

8, non-essential personnel shall enter the paint room.

 

maintenance:

1, daily room cleaning walls, floor and glass base, in order to avoid the accumulation of dust and paint dust;

2 per week to clean the inlet air filter, exhaust air filter to check whether there is product plug, such as room air pressure increase for no reason, you must replace the exhaust air filter;

3, should be replaced after every 150h floor separated dust fiber cotton;

4, should be replaced after every 30oh inlet dust filter,

5, monthly cleaning floor drip tray and clean diesel burner filter means;

6, each quarter should check inlet and exhaust motor drive belt slack.

7, should be cleaned every six months throughout the paint room and ground station network, check the circulating air valves, air intake and exhaust fan bearings, check the burner exhaust passage, sediment inside the tank clean, clean paint room Aqueous protective film and re-spraying .

8, each year should clean the entire energy converter comprising a combustion chamber and exhaust passage, every year or after every 1200h should replace cotton roof paint. Of course, to render a perfect car paint work, rigorous process, strict practices, skilled operating skills are indispensable premise, reasonable choice undeniable planning paint room, not only to the greatest extent possible to meet the High Level painting requirements, can be sprayed out in the shortest possible time flawless body paint, but also to bring the painting master safe, healthy, bright, comfortable working environment.

 

Development Status:

Domestic paint room affordable prices ranging from 22,000 to 60,000, the price of high-grade 6-15 million range, wide range of products. The main circulating types are: outdoor rain-paint room, paint room-temperature fuel, teaching-oriented spray paint room, large channel-type paint room, eco-friendly paint room, paint room telescopic movement, without pump water curtain paint room, infrared paint standard room and paint room and other different functions; the general assembly structure using the paint room, housing body with picture-pluggable insulation spray wall, good sealing, insulation performance, body side with working room door, facilitate staff access, aluminum edging the door, the door is equipped with a central observation window can always observe the dynamic room, paint room accessories are endless, higher usage are: fans, burners, lighting, floor, cotton filters , electric control box, the occurrence of rooms, paint light, efficient energy converters, etc., of course, depends on the specific configuration and model plant for their prospects of planning.

 

Air drop formula:

In 0.2-0.3m / s speed of downward mobility, so after painting the mist particles can not stay in the air, and the air is discharged directly outside the room through the bottom out. Such constant cycle conversion, so that when the painting room air cleanliness more than 98%, and into the air with a certain pressure, can be formed around the car a constant air flow to remove excess paint to maximize assurance quality paint.
