2014.09.03 12:56People often scratched for car paint to do and ask questions, so I searched for some information, sorting through changes to put it out, at the same time also let it be, by the way Understand the whole process of the car paint spraying, and the way to repair paint and simple maintenance of common sense.
About car paint
Car paint are generally baking paint. Car depot, frame, shell (sometimes manually repair) welding is complete, is the paint on the next procedure. Generally speaking, the first (high some Car is first the phosphating anticorrosion technology) primers. Light car shell in the paint like syrup tank, take out the baking primer; And then into the clean workshop, spray paint above by electrostatic painting process. Then in 200 Degrees or so the temperature of the drying. Elegant, also will again on a layer of varnish. In this way, the paint process're done. General paint several: ordinary paint; Metallic paint. Pearl paint. Ordinary paint will not By saying, the resin, pigments and additives. Metallic paint more aluminum powder; So after finish looks bright. Pearl paint, join the mica particles. Mica is very thin pieces of thing, so, Reflective direction, there will be a colorful effect. If it is metallic paint and varnish layer, car paint looks very bright, very beautiful. On color, white is the cheapest. For example The world first-class brand red pigment 25 times more expensive than the world first-class brand titanium dioxide probably; And the amount of titanium dioxide in the white paint is red pigment of about 5 times. Therefore, the cost of the red paint on color The five times higher than white paint. This is why some chinese-made color varieties so little: simple, low cost at the same time.
No matter what color of paint, the pigment in the images of torture (parameters) parameters (BBS) is to fade. In fact, not only the paint, any colored dongdong in the big sun May be fading. At this moment, the paint inside and how additives is very important. Such as light stabilizer, such as antioxidant. Unfortunately, good additive is very expensive. Many times, add The stand or fall of agent determines the paint how it feels. People must think some 2 years began to appear faded paint more than 5 years if brightness is new paint is poor. But in fact, there is no Faded paint. Many times, the manufacturer is more interested in: fade evenly. Try not to make different parts of the car appear off color.
New car hand, is the most easy to damage the paint. Car wash not careful, the paint will be injured. In fact, even if at the time of production line to organize, also have damaged the paint.
General small scratches, paint surface have scars, scars. The paint surface was shaving. There is no need to paint. Light, play computer or play a few times more with sand wax wax. Heavy, A polishing also is ok. A bit serious, we can see the color of the lower primer (many times, primer is deep color). Then, please look at the wound. In general, insurance Poles, rearview mirror, and some of the car wheel eyebrow these parts are engineering plastics. Will not rust. In addition to the ugly also no big problem. Don't paint tonic also doesn't matter. Other (torture), that is about to fill Paint, otherwise, even if it is a very small damage, steel will start to rust, by then, even if the touch-up is also difficult to prevent the embroidery.
About the touch-up
First of all, all places, even in the original factory, car pack good, touch-up don't use any "original paint"! If the repair shop to tell you they are using the "original paint", it must be Is lying to you. The reason is simple: it says to the original painting process said, good spray paint, with a temperature of 200 c. The finished car so many parts, how many ability of 200 degrees The temperature? Don't put car light, with only a car shell? Touch-up were repaired with special paint. Repair paint baking temperature is lower, the appearance of 7, 80 degrees.
Second, to repair the paint colors are repair before deployment. The reason is simple: your car may have opened a few years, the paint has begun to fade, although can't you see. If you stop Outside, the degree of different directions fade will be slightly different - the sun's rays. As possible and the original color would match, only now. Also, as much as possible in order to not appear off color, even You don't just fill a need to paint, the factory will put the whole piece to spray. For example, there is a place to fill on the door, then, is bounded by rubbing strip, upper or lower fan The spray. So, if there is a little bit off color is not easy to see.
Also, when buying a car for the beautiful, buy is pearl paint (in domestic cars seem to be no vehicle), touch-up, ready to cry. After filling the paint mica grain direction is Difficult (or almost impossible), as well as the original. Paint a little off color, make up the paint can also be one soon.
Computer color matching on the premise of operation personnel seriously now, with the paint and the original paint off color is the eye of the ordinary people could not tell the difference. This can be at ease. The key is: paint, use the set Prepare and sense of responsibility.
The possibility of not original paint touch-up. But in general, a garage, or would you recommend to special repair station designated repair paint brand. A good pit also use a good brand. For example, ici, such as Nippon. However, small store, even some special repair station may be less formal and in consideration of cost reduction using cheap paint (if not to say they are fake). The possible effects , 3 months later, the color difference. This, we almost impossible to identify users. Only look for the trust of the garage.
Although repair paint baking temperature is lower, but not equal to don't need baking or in what other way instead. If you find that there is no specific baking paint room, garage but with little "(iodine tungsten Heating lamp) ". Early in place! Unless you drive the bus.
Also, car factory production line, painting is carried out in the clean workshop. Although many pure domestic cars may not do it, but is not equal to it doesn't need. If you see the garage is dirty , grey is very large. I suggest you change the place. Otherwise, even if at the time of good-looking, over time, lacquer face blister, shell I have seen.
About the paint maintenance
First, don't like the bus driver with a bucket of water can wash the car. , and get a sand grinding paint only difference in degree. If it rained or ash is thick, also don't use a wax mop or cloth The dust ash. Simply wash the car.
Washing the car, a lot of water washing is very necessary. But most of the time, wash the car small 2 like vertical put to flush the paint with water cannons. In this case, the high pressure water to oil Damage to paint. Also, wash the car place if used special detergent as washing liquid is also very bad.
Although these damage once two times. But over time, can not be ignored.
In addition, now that new car tend to sell quickly. Your car could get its hands on just a few days out of the car factory. And baking varnish has a characteristic: general to delay for a period of time really strong and firm Hard. So, don't rush to wax new car. Three months later. After three months also try not to use hard wax. Hydrates paint, don't wash the car within one week. It's a rainy day there is no way.
Also, many new cars are now in the outer spray paint a layer of varnish. In this way, the surface light, good looking, also can protect the paint. This kind of car, you don't burn bag, what to seal glair. or What to do new car paint surface polishing. In that way, you just pay for your car paint down to the level of the low grade car.
