Car paint surface can be divided into two general types: Putong Qi and metallic paint. Pu Tongqi coating for the four structures, with a total thickness from about 80 m, Mohs hardness of about 0.4 to 0.5. Metallic coating for the five-story structure, with a total thickness of about 10 m, more than about 0.5 Mohs hardness.
Both Putong Qi or metallic paint car, its Decoration Resistance, hardness, anti-crack resistance, weather resistance, resistant to moisture and corrosion resistance, aging resistance and so on, have to rely on paint layer to achieve. Modern The fundamental purpose of car paint care and significance, not only to improve the car's decorative and protective coating and the coating layer of wax, but the use of modern technology can provide new technologies and new products to further enhance the finish of the physical and chemical indicators .
2, causing the surface film car damage, aging and cause loss of light
Surface paint damage caused by cars, aging and loss of light for two main reasons:
(1) natural elements: sand dust in the wind and percussion, the impact of mud during the rainy season; asphalt splash from the asphalt, gum insect feces, bird droppings and greasy classification against; in the atmosphere of various industrial effluents, acid, alkaline and ultraviolet radiation in sunlight erosion.
(2) human factors: a new car "on wax" method of goods selection, operation or improper; washing vehicles, water cannon pressure greater than the amount 7MPa; cleaning procedures or methods are not correct; daily casual vehicle with a dry cloth; use polish wax and other poor quality paint care products and regular use of polishing wax.
3, the surface of the initial nursing program new car
General, new car purchases are often accumulated some dust on the surface, many people are poor field conditions where only a bucket of water, a cotton dust will be removed, often at the moment is the human factor paint surface damage caused by the first time. The correct procedures should be:
(1) as far as possible using high pressure cleaner (pressure less than 5MPa) wash away the dust, and then carefully check whether the surface paint scratches, sagging, paint pit, rust, corrosion under the paint color and and so on. This would ensure the car's original factory paint surface quality.
(2) buy a new car, you can not rush to wax. At present, many beauty shops used wax the way to have two: one is mechanical, the body wash, wipe dry, then wax the wax machine coated cloth rotating wheel, surface grinding in the paint: another kind of hand-style, is the body wash dry, the paint or spray on wax and credit to liquid, and finally hold him in the car dry cotton cloth repeatedly rubbed hard. Appears to be doing painted car surface care, in fact, there is thin paint surface from scratches. With such "care to increase the number, color and more and polished significant loss of light appears until the last film, aging and exposure of the fill and so on.
