Common knowledge of paint: do you know the main culprits that damage the paint surface of car body?

Core tip: usually more than one year of use of vehicle paint may produce oxide film, traffic film and other paint defects Oxidation of paint surface The perennial sunlight is one of the main reasons to shorten the life of the car paint The ultraviolet in the sunlight will eventually cause the car coating oxidation Under the sun ultraviolet irradiation, the oil on the paint surface is excessively dispersed, which leads to the brightness and color depth of the paint surface greatly reduced, the paint surface slowly forms an oxide layer, the service life of the paint is shortened, and the phenomenon of black, white and lusterless appears traffic 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: usually use more than one year of vehicle paint may produce oxide film, traffic film and other paint defects One of the main reasons for shortening the life of car paint is that the paint is oxidized by sunlight all the year round Under the sun ultraviolet irradiation, the oil on the paint surface is excessively dispersed, which leads to the brightness and color depth of the paint surface greatly reduced, the paint surface slowly forms an oxide layer, the service life of the paint is shortened, and the phenomenon of black, white and lusterless appears Because of air friction, traffic film vehicles will produce strong static electricity Static electricity has a strong ability to absorb dust, oil and chemical dust It will gradually form a hard traffic film on the car body surface, which will lead to oxidation and corrosion of the paint surface Cracking usually occurs on the metallic paint If the metallic paint is not properly maintained or aged, it may produce a very fine crack The crack will continue to deepen until the "breakdown" of the whole paint layer This phenomenon is called cracking It is difficult to find the cracks by naked eyes at the initial stage, so when the cracks can be observed by naked eyes, it indicates that the damage of paint surface is serious When re spraying metal paint, if there is a problem with the construction quality of the paint, the resin in the paint may crack due to "shrinkage" The water mark is a ring-shaped mark, which is left by the evaporation of water droplets Almost all vehicles have water mark to varying degrees The chemical substances in the water mark will continue to react with the car paint when the car body is heated by sunlight, which will cause damage to the car paint The paint surface is oxidized, cracked and the car body surface cleaned with common cleaning agent is more likely to produce water marks When bird excrement, insect carcasses, leaves, tar pitch and other substances stay on the body surface for a long time, they will slowly react with the car paint and start to erode the car paint Their erosion speed is much faster than that of the water mark The paint damage caused by them is called erosion mark The pollutants in fading atmosphere are the main causes of fading and discoloration of car paint Fading and discoloration generally occur on the hood, roof and luggage compartment cover Scratches on car paint are mainly caused by improper daily maintenance For example, there are hard particles in the dust of car body surface during car cleaning, resulting in small scratches on the paint surface during car cleaning Frequent cosmetic maintenance of paint surface is easy to cause paint damage In addition to new cars, in order to remove all kinds of paint defects mentioned above, before sealing and coating, it is usually necessary to polish the paint surface first, even if the paint is waxed, if the paint defects are obvious, in order to achieve the best effect, the polishing process will be taken first The polishing of the paint surface can grind off the defective paint film and restore the luster of the paint surface, but at the same time, it can also make the paint thinner to a certain extent In addition, the operation requirements of polishing construction process are very high If the constructor is not professional enough, the paint layer may be worn through directly, causing irreparable damage to the paint surface, and only repainting can be done 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,
