As the saying goes, unexpected things happen, and driving on the road is the same. There are inevitably bumps and bumps, and when such work happens, as car owners, in order to maintain the beauty of their cars, they have to pay for their beauty. But are we spending money together to understand the common sense of car paint repair? Next, let Qingyuan Jinliang introduce you to the professional car paint repair experience!

Firstly, regarding car paint, the vast majority of international commercial cars are made of steel shells. In order to prevent embroidery and aesthetics, car paint is indispensable. Let's talk about paint first.

Car paint

Car paint一般都是烘烤漆。車廠里邊，車架、車殼焊接完結(jié)(有時(shí)還會(huì)進(jìn)行手工修補(bǔ))后，下一道工序便是上漆。一般來說，首先是底漆。將光車殼浸入糖漿 般的漆槽，取出烘干底漆；然后送人無塵車間，用靜電噴漆工藝噴上面漆。然后用200度左右的溫度烘干。講究點(diǎn)的，還會(huì)再上一層清漆。這樣，油漆工藝就功德圓滿了。一般面漆有幾種：一般漆；金屬漆；珠光漆。一般漆就不用說了，樹脂、顏料和添加劑。金屬漆多了鋁粉；所以完結(jié)今后看上去亮。珠光漆呢，參加的是云母粒。云母是很薄的一片片的東西，因而，反光有方向性，就有了色彩斑斕的效果。如果是金屬漆加上清漆層，車的油漆看上去就很亮，很漂亮。色彩上呢，白色無疑最廉價(jià)。打個(gè)比方，國際一流品牌紅顏料比國際一流品牌鈦白粉大約貴25倍；而白色油漆里鈦白粉的用量是紅顏料的5倍左右。因而，紅油漆用在色彩上的成本就比白油漆高了5倍。這便是為什么有些國產(chǎn)車色彩種類那么少的原因：簡(jiǎn)單，且成本低。

No matter what color of paint, its pigments will fade in sunlight. In fact, not only the car paint, but any colorful items may fade in the bright sun. At this point, the additives added to the paint become very important. For example, light stabilizers, antioxidants, etc. Unfortunately, good additives are very expensive. Many times, the quality of additives determines how this paint feels. People will definitely think that a paint that starts to show significant fading in 2 years is worse than a paint that is as shiny as new in 5 years. But in reality, there is no paint that does not fade. Many times, the factory places more emphasis on evenly fading the color. Try to avoid color differences in different parts of the car.

The simplest damage to a new car is the paint. Careless car washing can cause damage to the car paint. In fact, even when loading things on the production line, there is still work that damages the paint.

Generally small scratches, scratches on the paint surface, and the scars turn white. That's because the paint has been scratched on the surface. There is no need to touch up the paint. Lightly, use sand wax to beat or many times to beat the wax. Heavy, just a polishing is enough. More seriously, the color of the lower layer of primer can be seen (many times, the primer is dark). So, please take a look at the area of the scar again. Generally speaking, the bumper, rearview mirror, and some car wheel arches are made of engineering plastic. It will not rust. Apart from ugliness, there is no major problem. It doesn't matter whether the paint is patched or not. Other things, then we need to repaint the car. Otherwise, even if it is a small damage, the steel plate will start to rust. By then, even repainting will be difficult to prevent rust.
