Paint knowledge | overall strategy of automobile paint surface maintenance

Core tip: car paint knowledge car paint is generally baking paint In the car factory, after the frame and body are welded and repaired manually, the next process is painting Generally speaking, the first is primer Dip the white leather body into the syrup like paint tank, take out the drying primer; then send it to the dust-free workshop, spray the top paint with the electrostatic spraying process, and then dry it at a temperature of about 200 ℃ Some will be covered with varnish In this way, the painting process is finished There are several kinds of general finishing paint: common paint, metal paint, pearlescent paint The main components of common paint are resin, pigment and additive; the metallic paint has more aluminum powder, so after completion Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: car paint knowledge car paint is generally baking paint In the car factory, after the frame and body are welded and repaired manually, the next process is painting Generally speaking, the first is primer Dip the white leather body into the syrup like paint tank, take out the drying primer; then send it to the dust-free workshop, spray the top paint with the electrostatic spraying process, and then dry it at a temperature of about 200 ℃ Some will be covered with varnish In this way, the painting process is finished There are several kinds of general finishing paint: common paint, metal paint, pearlescent paint The main components of common paint are resin, pigment and additive; metallic paint has more aluminum powder, so it looks bright after completion; pearlescent paint is added with mica particles Mica is a very thin piece, with reflective, there will be a colorful effect If it's metal paint and a clear paint layer, the car paint looks very dazzling Pay attention to daily maintenance 1 Before, during and after the use of the vehicle, the dust on the vehicle body shall be removed in time to minimize the adsorption of dust by the static electricity of the vehicle body; 2 Wash the vehicle in time after rain After rain, the rain stains on the car body will gradually reduce, making the concentration of acid substances in the rain gradually increase If the rain stains are not washed with water as soon as possible, the finish paint will be damaged over time 3 When washing the car, it should be carried out after the engine is cooled Do not wash the vehicle in the hot sun or high temperature, so as not to leave traces when the detergent is dried Usually wash the vehicle by yourself with special detergent and neutral living water, instead of alkaline washing powder, soap water and detergent, so as to prevent the grease in the paint from washing off and accelerate the aging of the paint 4 Clean and soft cloth or sponge shall be used to wipe the vehicle to prevent metal scraps and sand from mixing Do not use dry cloth, towel or sponge to wipe the vehicle to avoid scratches When wiping, wipe gently from top to bottom along the direction of water flow, and do not circle or wipe horizontally 5 Some special traces with strong corrosiveness (such as asphalt, bird manure, insects, etc.) shall be removed in time For this, it must be cleaned with a special cleaner Do not scrape with a blade or use gasoline to eliminate it at will, so as to avoid damaging the paint surface Paint repair generally small scratches, such as paint surface scars, white scars or even paint surface is scraped into hairline shape, in fact, there is no need to repair paint Light ones can be treated with car wax; heavy ones can be polished More serious, you can see the color of the underlying primer (for example, the white primer underneath) Generally speaking, bumpers, rear-view mirrors and wheel brows are plastic parts, which will not rust If they have small problems, it doesn't matter whether they are repaired or not If it is scraped onto the steel plate of the car body, it needs to be repainted Otherwise, even if it is a small damage, the steel plate will start to rust At that time, even the repainting effect is not ideal First of all, all places, even in the original factory, will not use any "original factory paint"! If the repairer tells you that they are using "original paint", it must be deceiving you, in order to increase the maintenance cost The reason is very simple: the original factory spray painting process spray paint, with 200 degrees temperature baking And so many parts on the finished car, how many can withstand the temperature of 200 degrees? But generally, the manufacturer will recommend the specified brand of touch up paint to the special maintenance station Good repair stations will also use good brands Secondly, the color of the repair paint is distributed before repair The reason is simple: your car may have been driving for several years, and the paint has begun to fade, although you can't see it If you park outside, the color will fade slightly in different directions If you want to match the original color as much as possible, you can only adjust it now The color difference between the paint and the original paint is indistinguishable from the eyes of ordinary people You can rest assured Also, in order to avoid color difference as much as possible, even if you only need to touch up a small piece of paint, the maintenance shop will spray the whole piece again For example, if there is a place on the door that needs to be mended, then, take the anti scratch strip as the boundary, and spray the upper or lower half of the door completely In this way, if there is a little color difference, it is not easy to see In this way, it's not hard to understand why the front left bumper is scratched and the whole bumper needs to be painted At that time, we can't say that the maintenance shop is killing the customer It is necessary to wash the car with plenty of water But most of the time, car wash workers like to use high-pressure water gun to wash paint vertically In this case, high-pressure water can also damage the paint In addition, it is common for washing places to use washing powder to pretend to be special washing liquid Although these injuries can not be seen twice at a time But for a long time, the harm can not be ignored New cars are selling fast now The car you've got may have just come out of the garage a few days ago And baking paint has a feature, generally to lag a period of time to really firm, hard So don't wax your new car Three months later Try not to use hard wax after three months It has been repainted It's better not to wash the car in a week Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
