2020-04-20 513

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!

清遠(yuǎn)汽車修補(bǔ)漆

轎車補(bǔ)漆流程

轎車補(bǔ)漆流程一:首先確定修補(bǔ)規(guī)模與傷損程度。

細(xì)心查看傷損部位,并依據(jù)傷損巨細(xì)確定適宜的修補(bǔ)辦法。假如傷損超過(guò)該部件的三分之一應(yīng)采納過(guò)度修補(bǔ)的辦法修正,過(guò)度修補(bǔ)便是清漆整部件噴涂,色漆從傷損處到原漆處過(guò)度,最大化的保留了原車色漆,一起也避免了色差的問(wèn)題。

轎車補(bǔ)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?zhàn)?,打膩?zhàn)訒r(shí)先用P240的砂紙把傷損處打磨粗糙提高膩?zhàn)拥母街?,依?jù)傷損巨細(xì)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(rùn)滑。底漆干燥后,細(xì)心檢查有沒(méi)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(guī)模打磨潤(rùn)滑,接口處要用P2000#砂紙細(xì)心打磨以便接口更好的融合。

轎車補(bǔ)漆流程三:遮蔽除油。

先用風(fēng)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(xì)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(xì)擦一編就能夠噴涂色漆了。

轎車補(bǔ)漆流程四:噴涂色漆與清漆。

將調(diào)好的色漆稀釋充沛拌和,并過(guò)濾,噴涂時(shí)要注意控制規(guī)模,氣壓調(diào)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(guò)渡,直到?jīng)]有色差停止,確認(rèn)色漆沒(méi)有色差徹底干燥后就能夠噴涂清漆了。

轎車補(bǔ)漆流程五:駁口處理。

清漆噴好后進(jìn)行駁口處理,將亮油和引發(fā)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(shí)氣壓要稍大從新噴漆處向原漆過(guò)渡,不能噴涂太厚要均勻過(guò)渡。

轎車補(bǔ)漆流程六:烘烤。

噴涂前將UV烤燈電源接好,依據(jù)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(yù)熱好后就能夠烘烤,烤時(shí)陪戴好專用護(hù)目面罩或眼鏡,先烤邊緣再烤中心。

轎車補(bǔ)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(diǎn)、流淚,打磨時(shí)接口處要輕磨,打磨好后用高速拋光機(jī)和專用研磨劑進(jìn)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(dá)豐滿光澤,接口處要輕拋?zhàn)龅竭m可而止,過(guò)了接口就會(huì)顯露來(lái),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(bǔ)漆

在車輛的直接刮擦中一般都會(huì)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(bǔ)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(hù),并且這樣的劃痕也很不容易發(fā)現(xiàn),不影響漂亮。對(duì)于很多對(duì)車“溺愛(ài)”的車主,假如發(fā)現(xiàn)小的刮痕無(wú)法判別深淺的時(shí)分,能夠用手指頭去接觸,一般摸上去感覺(jué)不到有顯著凹凸感的劃痕就闡明沒(méi)有傷及底漆,能夠暫時(shí)不論,或許稍后處理,可是摸上去假如顯著能感覺(jué)到有“一條線”,這樣的劃痕就現(xiàn)已傷到底漆,要立刻處理。

轎車補(bǔ)漆辦法

1、補(bǔ)漆筆可處理小劃痕

假如銹蝕不很嚴(yán)重,可先用極細(xì)的水砂紙蘸水輕輕磨去銹斑,但切忌無(wú)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(méi)有原廠漆,能夠購(gòu)買一支補(bǔ)漆筆,用補(bǔ)漆筆進(jìn)行上色處理。這樣的處理盡管沒(méi)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(kuò)大、加重的作用。

2、電腦調(diào)漆噴涂法

它是利用電腦調(diào)漆,調(diào)漆比例比較精確,現(xiàn)在電腦配色在操作人員仔細(xì)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(zhǔn)調(diào)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(shí)刻久。這要求要專業(yè)、細(xì)心物質(zhì)好,修正作用比較好。電腦調(diào)漆修正法是現(xiàn)存的補(bǔ)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(yè)度,我們一般的人很難有那個(gè)水平,所以盡量挑選專業(yè)的轎車噴漆中心來(lái)進(jìn)行。假如操作不當(dāng)很難保證噴涂后的刮痕處與其它地方形成一致的作用。
