Paint room used in automotive, machinery, hardware, furniture, chemical and other industries for the surface paint, paint job. In recent years, auto repair plant around the fire accident，the reason, mostly in the paint room. Most of the chemicals used in the process of automobile paint production and painting are easy to catch fire. The high-temperature environment of paint room is accompanied by paint and flammable materials, so that the paint room has become a high-risk operation point. However, garage repair mechanic non-standard operation, but also increased the number of fire in the paint room. August 2008, a car repair shop in a fire, the local fire brigade sent two fire engines 10 officers and men go to fight. After the reconnaissance, it was found that the fire was located in the paint shop of the repair shop. The paint room also contained 2 barrels of heated diesel oil and a large amount of paint for paint. Seven repair shops connected side-by-side with the paint house were parked with the Audi A6, Passat and other more than 10 limousines, repair shop is surrounded by a large number of houses. Thanks to the timely control of the fire, or if it caused a large area burning, an explosion, the consequences would be disastrous.

Cause of fire accident

Paint room fire is mainly caused by the heat exchanger that is commonly known as the hearth, in which the selection of the hearth, the thickness of the wall, the size of the size is very crucial. Lead to paint room for a number of reasons, from the quality of paint room, the following three kinds of conditions are more likely to cause fire.

1. Furnace texture is good or bad

Since the paint room fire is mainly from the hearth, the quality of the hearth material is very crucial. Large baking room furnace chamber is made of standard stainless steel, good quality, high temperature to about 1100 ℃, while some small-scale workshop baking room furnace is generally used stainless steel or stainless steel, the high temperature of only 700 ℃ or so. When the paint room in use, the normal temperature of the flame is between 900 ~ 1000 ℃, defective stainless steel material in the frequent combustion process is easily burned, resulting in the proliferation of flame into the house, the flame contact the paint room Of the powder, causing a fire.

The same stainless steel, the thickness is not the same, the fire will have a great impact. Good paint room furnace thickness is 2.0mm or 2.5mm, but some baking room furnace thickness of only 1.2mm or 1.5mm, the furnace is too thin, its service life is also short, paint room in the use of the period of time, easy to produce perforation , Resulting in paint room fire. If the material used in the furnace itself is defective, coupled with too thin, the probability of fire in the paint room is even greater.

2. The furnace volume is too small

Another important reason that causes the paint room to catch fire is that the furnace volume is too small. A good paint room fire only in the middle part of the furnace combustion, the normal combustion flame will not burn the heat exchanger wall. The length of the qualified furnace is 1.4m, so that the flame can only be burned in the middle part, that is to say, it does not contact with the combustion, so that the service life of the stainless steel becomes longer. At the same time, the flame can fully contact with the air to ensure uniform force when baking. And because of the material is more expensive, the volume of some baking room furnace is only 90cm, it is easy to make the flame and the wall in direct contact, not only lead to uneven force in the baking process, but also shorten the life of the furnace, increasing the furnace Perforated may.

3. Improper operation of mechanics

Paint room in the paint process due to improper operation of mechanics caused by the fire danger. First, due to work needs, maintenance companies overtime more work in the state of burnout will inevitably lead to the accident; Second, many spray painters and operators lack of chemicals, dangerous goods (including paint and organic solvent Agent) basic performance, especially the lack of safety knowledge of the use of chemicals and dangerous goods; Third, many repair shop staff did not undergo a rigorous training assessment on the job, completely do not understand the safe production practices; Fourth, due to mess Put, run, run, drip, leakage caused by accidents, and even open fire involved, resulting in a fire.

In the daily maintenance, to maintain the best results of the paint room, the following should be regularly cleaned and checked: daily cleaning room dust and paint accumulation; cleaning air intake every week, check the exhaust dust If there is any dust accumulation in the net, if the air pressure in the room increases for no reason, the exhaust air filter must be replaced. The filter dust should be replaced every 150h. The inlet air filter should be replaced every 300h. Taichung dish, and clean the burner on the diesel filter device; Check the intake and exhaust air motor drive belt every quarter is flabby; Every six months should clean the entire paint room and the ground, check the circulating air valve, into the wind and Exhaust air bearings, check the burner exhaust channels, clean the tank of sediment, clean the paint water repellent paint room and re-spray; every year should clean the entire heat exchanger, including the combustion chamber and the exhaust channel, every year or every work 1200h Should be replaced paint roof cotton.

2 paint room to be checked regularly

Baking room after use for some time, electrical appliances, wires gradually aging, resulting in short circuit, open circuit and cause fire; exhaust fan will also be used in the process of accumulation of residual paint after painting, require the operator to conduct regular inspection of the paint room clean, eliminate hidden dangers.

3. Strictly abide by the rules and regulations

Into the paint room operations, must prepare the required paint, the day that the water and the required equipment. Paint the vehicle into the paint before the house, the chassis should be the first fender dirt, dust clean, prohibited in the paint spray booth to clean the dust; spray paint job wear anti-static work clothes; smoking in the spray booth is strictly prohibited; spray paint Do not open the painting room door during operation; Do not set the thermostat above 50 ℃ during the insulation and drying operation; Regularly clean the water pump to check the reliability of the electrical circuit; Check the air inlet filter to prevent the blockage; Oil refueling room should not leak oil; monthly check should be carried out on the diesel tank.

1. minor repair their own hands

For another air filter, install a light bulb such a small live completely unnecessary on the 4S shop, light queuing had to wait for an hour, have to catch a high working hours, there is time to finish their own. So like this kind of primary car knowledge, should have given yourself some tutoring. Like brake light bulbs such parts are loss of goods, even if the new car is also inevitable damage, so as long as you carefully study the car tail light simple structure, you can go to the street to spend 5 dollars to buy a light bulb, and then their own hands for the car for On, so that both save the queuing of the pain, but also increased the exchange of love between the car, can be described as two birds with one stone.

2. Maintenance to the fast repair center

General household cars every 5,000 kilometers to be carried out oil, machine filter replacement, if the times to 4S shop replacement, time-consuming, laborious, but also cost money. So for this kind of no technical content of the live can be assured to the community quickly repair shop care. If the shop to provide oil and other raw materials are not enough rest assured that you can go to the 4S shop to buy bottles of oil, and then go to the shop to spend 10 minutes to solve the problem, so that up to pay 20 yuan wages, but also Free repair workers on the chassis, the tire of the detailed examination, why not it?

3. Susceptibility to 4S shop free diagnosis

Now the cars are equipped with complex electronic systems and sophisticated mechanical components, in the event of a larger failure, definitely not roadside stalls or auto parts can be resolved. Want to repair a complex structure of modern cars, in addition to have a wealth of professional experience, the more important is to rely on extremely advanced electronic equipment auxiliary maintenance, and this is what those shops do not have, then you have to believe Brand store strength. Now 4S shop in order to win customers basically fault detection is free, so you can run a few more 4S shop first test the root causes of failure, if several stores are given the same answer, it can basically determine the problem where the The But then you do not have to rush to pay repair, if the maintenance process is not complicated, then you can buy accessories from the 4S store, and then to the auto parts to find repair shop, of course, if the electronic device, it is best not to Province that money.

4. Overhaul to be professional

Cars are sophisticated machines, superficial small faults can also count on those "guerrillas", but if you really encounter a greater failure, then you have to go to a professional 4S shop. For the maintenance of the engine, gearbox, chassis, computer and other parts, my point of view is sure to repair the 4S shop. Give me a personal experience of the example of it, a friend of the Bora, had only slightly engine oil, the results in a small repair shop after the repair have been unable to beat the car, high-speed sound and many other inexplicable problems, the last that Friends had to spend money to 4S shop for a thorough repair, the results inside and outside also lost a thousand dollars. So, here also to remind you that the key parts of the fault, we must choose 4S shop repair.

5. Do not blindly follow the original accessories

To their own Jetta, for example, the air head of the air filter outside the plastic box in the 4S shop to buy more than 200 yuan, while the auto parts of the city 80 yuan a sub-factory streets are, according to my visual quality is not bad The So I did not hesitate to Auto Parts City, selected vice factory, has been used for more than two years, there is no problem. In fact, the election of vice plant is also a principle: 1. Like this plastic parts, even if the deputy factory is not as durable as the original, it will not let your car immediately broke down, big deal 80 yuan and then one; Air filter plastic box does not belong to the core of the car body, if there is a problem will not cause permanent damage to the car; Like the brake pads, tubing, belts and other key components of these I will definitely not use the deputy factory, because the quality of sub-factory accessories, after all, unreliable, if these key parts of the problem, then you can save money.

In the election time, some reasonable objective factors, including the compartment space, fuel economy and price are very important. But for many of us, it is difficult to put away personal subjective feelings when buying a car.

In the future, the evaluation of the owner may change due to factors such as reliability, but this result allows us to know the most pleasant car at this stage.

TOP 10 MINI 838 points

First debut is BMW's entry brand - MINI, although many owners will choose a wide range of options, resulting in the final landing price is not cheap, but after all, is a relatively mainstream models. It is undeniable that the MINI will fashion the appearance and movement of driving a good combination of feelings, so that owners are attracted to this.

TOP 9 Jaguar 838 points

Jaguar and MINI, the same is the British brand, scores are exactly the same. Like the MINI, from the F-TYPE and F-PACE, it is a good combination of stylish appearance and attractive dynamic driving experience. The difference is that Jaguar can provide good driving quality, its appearance is classic and elegant. Jaguar offers some excellent engines, such as the V6 and V8 mechanical supercharged engines, as well as the power of the diesel engine.

TOP 8 Lexus 842 points

Lexus is the only Japanese brand in the top ten. Toyota's high-end brand provides a maverick appearance (here to discuss its good part) It is undeniable that this makes the car look luxurious, although it does not always make people feel driving up fun, but the owners really like LC500 on the 5.0 naturally aspirated engine.

TOP 7 Cadillac 843 points

Cadillac to seventh of the advantages of ranking seventh. Like Jaguar, most of Cadillac's models can also feel beautiful and well-driven, but with one exception, XTS, the car represents the old predecessor of the Cadillac era that we wanted to forget. Fortunately, XTS will be discontinued.

TOP 6 Lincoln 849 points

When we saw Lincoln ranking so high, more than the Cadillac, Jaguar and Lexus, we are some surprise. Lincoln's models are still in keeping with the parent company - Ford's inextricably linked, but this is not necessarily a bad thing, for us is not very important. The mainland, and the upcoming pilots will give a better impression. Lincoln also began to provide some unique services, such as Lincoln Black Mark Service, will provide a similar excellent driving service.

The first five have four German brands, Mercedes-Benz is the lowest score that. Now the new Mercedes models have a gorgeous interior (CLA, GLA and other models except), and good performance, especially those in the rear marked AMG three letter models.

Audi than the trigeminal star won more than 3 points, ranked fourth. Owners are very fond of Audi's modern interior design and high-tech equipment, especially the virtual cockpit. Audi can balance comfort and maneuver and provide some powerful engines.

TOP 3 BMW 855 points

BMW only lead the Audi 1 points. The ultimate driving machine for BMW to create a lot of people like the car, but in recent years, its car has become less pure. For some people, it's also a good thing to see BMW's car more comfortable. But when discussing the best driving experience, the owners are still the most favorite BMW. It can make it better.

TOP 2 Czech Republic 869 points (Note: Now the Czech has been a separate brand)

Czech Republic is the only one in the top ten Korean brand, and made the second place results, impressive. Not only that, it leads the third of the BMW up to 14 points. The overall quality and driving experience of the Jeanne G80 SPORT still needs to be improved, but we can not talk too much about this score, after all, it is decided by the owner.

TOP 1 Porsche 884 points

Ranked # 1 Porsche ahead of Jennings 15 points. We are not surprised. Porsche's sports car, from Boxster to 911, is the best in the whole field, while Porsche has given Panamera, Macan, Cayenne the same sport, which even makes Panamera's appearance acceptable, so what else Do not love Porsche? Obviously No.
