Generally, a new car is painted with a total of 4 layers of paint:
1、電泳漆層:這里要提一下在電泳漆層之前有一個工序是對鈑金磷化的,首要是在鈑金外表構(gòu)成一層不溶于水的磷化膜,維護鈑金金屬,提高防腐蝕才能。電泳漆層涂裝是將整個車身悉數(shù)泡到電泳池里面,無死角翻滾侵泡,首要效果是防銹、防銹、是車身防銹的底層。
電泳漆層
2、中涂底漆層:其實電泳漆層過后并不是直接上中涂底漆,我們知道整個轎車,簡單受到腐蝕的一定是底盤,并且是嚴重,所以轎車底盤會再上一層反腐漆,雙重維護,即“底盤裝甲”。之后中涂底漆層,首要起填充效果,填充一些凹陷和小瑕疵,作為色漆層與電泳漆層隔離層,可以提高色漆層的裝飾性。當然肯定也有防腐效果的,

3、色漆層:這一層便是轎車油漆色彩的展現(xiàn),有素色漆、金屬漆(含金屬顆粒的漆)。
4、清漆層:維護色漆層,增加光亮度。耐紫外線、耐候性強。
以上是歸于轎車原廠漆涂裝漆層。除了色漆層不需求烘烤,其他三個漆層需求烘烤,人們把這種涂裝工藝叫做“四涂三烤”,烘烤溫度需求到達170℃以上。傳聞現(xiàn)在有轎車廠商選用“三涂二烤”,去掉了中涂底漆層,這種轎車涂裝工藝將大大環(huán)保和節(jié)能。
轎車油漆修補涂裝一般是這5層油漆,僅僅運用的資料不同。分別為:環(huán)氧底漆層,原子灰層、(中涂底漆層)、色漆層、清漆層,為什么我中途底漆層要打上括號呢,便是由于有些不正規(guī)的為了節(jié)約成本會換成紅灰,乃至省掉掉。因而轎車油漆修補,廉價沒好貨(活)。好活不廉價。
