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!
轿车补漆流程
轿车补漆流程一:首先确定修补规模与伤损程度。
细心查看伤损部位,并依据伤损巨细确定适宜的修补办法。假如伤损超过该部件的三分之一应采纳过度修补的办法修正,过度修补便是清漆整部件喷涂,色漆从伤损处到原漆处过度,最大化的保留了原车色漆,一起也避免了色差的问题。
轿车补漆流程二:底层处理。
清洗掉伤损部位周围的泥沙,假如划伤较深就需求打腻子,打腻子时先用P240的砂纸把伤损处打磨粗糙提高腻子的附着力,依据伤损巨细取适量的原子灰和固化剂均匀拌和,然后再用P800砂纸打磨润滑。底漆干燥后,细心检查有没有小沙眼,假如有就要用填眼灰处理,然后用1000#砂纸把底漆及要喷涂的规模打磨润滑,接口处要用P2000#砂纸细心打磨以便接口更好的融合。
轿车补漆流程三:遮蔽除油。
先用风枪把部件缝隙的水泽及尘埃吹洁净再用遮蔽纸把喷涂部件以外的部件细心遮蔽好,然后用纸巾蘸少量除油剂把喷涂部件擦拭一遍,再用除尘布合作气抢将喷涂部件仔细擦一编就能够喷涂色漆了。
轿车补漆流程四:喷涂色漆与清漆。
将调好的色漆稀释充沛拌和,并过滤,喷涂时要注意控制规模,气压调在2KPa要干喷,喷一遍要用专用除尘布擦一次,先隐瞒底漆逐步向外过渡,直到没有色差停止,确认色漆没有色差彻底干燥后就能够喷涂清漆了。
轿车补漆流程五:驳口处理。
清漆喷好后进行驳口处理,将亮油和引发剂混合好的亮油和驳口水按照比例混合(混合亮油1:驳口水10)在接口处喷涂,喷涂时气压要稍大从新喷漆处向原漆过渡,不能喷涂太厚要均匀过渡。
轿车补漆流程六:烘烤。
喷涂前将UV烤灯电源接好,依据喷涂部位放置好烤灯方位以便利操作,喷完清漆后3分钟翻开烤灯。预热好后就能够烘烤,烤时陪戴好专用护目面罩或眼镜,先烤边缘再烤中心。
轿车补漆流程七:打磨抛光。
打磨抛光需求用2000#美容砂纸将漆面打磨成哑光并祛除脏点、流泪,打磨时接口处要轻磨,打磨好后用高速抛光机和专用研磨剂进行抛光,打磨后抛光要先用中粗度研磨剂初抛再用微晶研磨剂精抛直到到达丰满光泽,接口处要轻抛做到适可而止,过了接口就会显露来,抛不到位不亮。清理好部件边缝和车身就能够交车了。
怎么判别是否需求补漆
在车辆的直接刮擦中一般都会伤及底漆和车体,可是一些由于小树枝的刮擦引起的小刮蹭是否需求补漆呢?车漆假如仅仅外部被划到,一般不需求立刻处理,由于车体外还有一层底漆维护,并且这样的划痕也很不容易发现,不影响漂亮。对于很多对车“溺爱”的车主,假如发现小的刮痕无法判别深浅的时分,能够用手指头去接触,一般摸上去感觉不到有显着凹凸感的划痕就阐明没有伤及底漆,能够暂时不论,或许稍后处理,可是摸上去假如显着能感觉到有“一条线”,这样的划痕就现已伤到底漆,要立刻处理。
轿车补漆办法
1、补漆笔可处理小划痕
假如锈蚀不很严重,可先用极细的水砂纸蘸水轻轻磨去锈斑,但切忌无方向地乱磨,要同向直线打磨。等彻底擦净后,涂上一层底漆。若是新的刮伤,可擦净后直接涂上底漆。之后,假如车辆配有小罐原厂漆,就能够等底漆干了后,再用水砂纸将其磨平,在底漆之上把原厂漆涂上。假如没有原厂漆,能够购买一支补漆笔,用补漆笔进行上色处理。这样的处理尽管没有去美容店处理作用好,但假如是小的或许不醒目处的伤痕,也能够起到防止锈迹扩大、加重的作用。
2、电脑调漆喷涂法
它是利用电脑调漆,调漆比例比较精确,现在电脑配色在操作人员仔细的前提下,配出的漆和原漆的色差是普通人的眼睛分辨不出的。一起,由所以电脑精准调漆,所以漆的依附度比较高,在修正之后漆表层不易由于空气的侵蚀而脱落,修正作用好,修正后保持的时刻久。这要求要专业、细心物质好,修正作用比较好。电脑调漆修正法是现存的补漆一切的手法傍边,轿车漆层刮痕最快速的一种。
3、喷涂修正法
由于喷涂法需求必定的专业度,我们一般的人很难有那个水平,所以尽量挑选专业的轿车喷漆中心来进行。假如操作不当很难保证喷涂后的刮痕处与其它地方形成一致的作用。
