In ordinary accidents, car scratches or small bumps play a dominant role. As the saying goes, "If you often walk by the river, where are your shoes not wet?" The vast majority of car owners have encountered car scratches. Some scratches are inconspicuous, such as accidental scratches or careless car washing, which can damage the paint. Generally, minor scratches can cause the surface of the paint to turn white. That's because the paint surface has been scratched, but the primer has not been exposed, so there is no need to touch up the paint. Polish with coarse wax or apply a few rounds of wax, and the scratches gradually disappear. For severe scratches, if the color of the base primer can be seen, generally speaking, the bumper, rearview mirror, and some car wheel arches are made of engineering plastic and will not rust. Apart from being ugly, there is no major problem. Whether or not to touch up the paint depends on the owner's own requirements. But if these severe scars appear on other parts of the car body, it will require repainting. Below, the editor of Xianji.com will provide us with a specific introduction to the relevant knowledge of car repainting, including the process of car repainting and how to determine whether repainting is needed? How to use the naked eye to distinguish between good and bad car paint repair methods, car paint repair precautions, and car paint repair effects? How to maintain the car after repainting? Let's take a look together!
轎車補漆流程
轎車補漆流程一:首先確定修補規模與傷損程度。
細心查看傷損部位,并依據傷損巨細確定適宜的修補辦法。假如傷損超過該部件的三分之一應采納過度修補的辦法修正,過度修補便是清漆整部件噴涂,色漆從傷損處到原漆處過度,最大化的保留了原車色漆,一起也避免了色差的問題。
轎車補漆流程二:底層處理。
清洗掉傷損部位周圍的泥沙,假如劃傷較深就需求打膩子,打膩子時先用P240的砂紙把傷損處打磨粗糙提高膩子的附著力,依據傷損巨細取適量的原子灰和固化劑均勻拌和,然后再用P800砂紙打磨潤滑。底漆干燥后,細心檢查有沒有小沙眼,假如有就要用填眼灰處理,然后用1000#砂紙把底漆及要噴涂的規模打磨潤滑,接口處要用P2000#砂紙細心打磨以便接口更好的融合。
轎車補漆流程三:遮蔽除油。
先用風槍把部件縫隙的水澤及塵埃吹潔凈再用遮蔽紙把噴涂部件以外的部件細心遮蔽好,然后用紙巾蘸少量除油劑把噴涂部件擦拭一遍,再用除塵布合作氣搶將噴涂部件仔細擦一編就能夠噴涂色漆了。
轎車補漆流程四:噴涂色漆與清漆。
將調好的色漆稀釋充沛拌和,并過濾,噴涂時要注意控制規模,氣壓調在2KPa要干噴,噴一遍要用專用除塵布擦一次,先隱瞞底漆逐步向外過渡,直到沒有色差停止,確認色漆沒有色差徹底干燥后就能夠噴涂清漆了。
轎車補漆流程五:駁口處理。
清漆噴好后進行駁口處理,將亮油和引發劑混合好的亮油和駁口水按照比例混合(混合亮油1:駁口水10)在接口處噴涂,噴涂時氣壓要稍大從新噴漆處向原漆過渡,不能噴涂太厚要均勻過渡。
轎車補漆流程六:烘烤。
噴涂前將UV烤燈電源接好,依據噴涂部位放置好烤燈方位以便利操作,噴完清漆后3分鐘翻開烤燈。預熱好后就能夠烘烤,烤時陪戴好專用護目面罩或眼鏡,先烤邊緣再烤中心。
轎車補漆流程七:打磨拋光。
打磨拋光需求用2000#美容砂紙將漆面打磨成啞光并祛除臟點、流淚,打磨時接口處要輕磨,打磨好后用高速拋光機和專用研磨劑進行拋光,打磨后拋光要先用中粗度研磨劑初拋再用微晶研磨劑精拋直到到達豐滿光澤,接口處要輕拋做到適可而止,過了接口就會顯露來,拋不到位不亮。清理好部件邊縫和車身就能夠交車了。
怎么判別是否需求補漆
在車輛的直接刮擦中一般都會傷及底漆和車體,可是一些由于小樹枝的刮擦引起的小刮蹭是否需求補漆呢?車漆假如僅僅外部被劃到,一般不需求立刻處理,由于車體外還有一層底漆維護,并且這樣的劃痕也很不容易發現,不影響漂亮。對于很多對車“溺愛”的車主,假如發現小的刮痕無法判別深淺的時分,能夠用手指頭去接觸,一般摸上去感覺不到有顯著凹凸感的劃痕就闡明沒有傷及底漆,能夠暫時不論,或許稍后處理,可是摸上去假如顯著能感覺到有“一條線”,這樣的劃痕就現已傷到底漆,要立刻處理。
轎車補漆辦法
1、補漆筆可處理小劃痕
假如銹蝕不很嚴重,可先用極細的水砂紙蘸水輕輕磨去銹斑,但切忌無方向地亂磨,要同向直線打磨。等徹底擦凈后,涂上一層底漆。若是新的刮傷,可擦凈后直接涂上底漆。之后,假如車輛配有小罐原廠漆,就能夠等底漆干了后,再用水砂紙將其磨平,在底漆之上把原廠漆涂上。假如沒有原廠漆,能夠購買一支補漆筆,用補漆筆進行上色處理。這樣的處理盡管沒有去美容店處理作用好,但假如是小的或許不醒目處的傷痕,也能夠起到防止銹跡擴大、加重的作用。
2、電腦調漆噴涂法
它是利用電腦調漆,調漆比例比較精確,現在電腦配色在操作人員仔細的前提下,配出的漆和原漆的色差是普通人的眼睛分辨不出的。一起,由所以電腦精準調漆,所以漆的依附度比較高,在修正之后漆表層不易由于空氣的侵蝕而脫落,修正作用好,修正后保持的時刻久。這要求要專業、細心物質好,修正作用比較好。電腦調漆修正法是現存的補漆一切的手法傍邊,轎車漆層刮痕最快速的一種。
3、噴涂修正法
由于噴涂法需求必定的專業度,我們一般的人很難有那個水平,所以盡量挑選專業的轎車噴漆中心來進行。假如操作不當很難保證噴涂后的刮痕處與其它地方形成一致的作用。
