当汽车真皮座椅受到损伤破口时,可以用粘补的方法进行修补。具体操作方法如下:
1、出现微小的裂口时,在裂口中涂上丙烯酸树脂,然后把裂口对齐,用吹风桶烘干。
2、出现较大破口时,取一块比破口略大一些的元纺衬,并在破口上面垫一层棉布,用熨斗压烫定型,当革面平整后将垫布取下,用吹风桶烘干。
3、当真皮出现较长的撕裂口时,取质地薄软的丝绸或棉的条状织物,将其垫在撕裂口下面。从裂口处给织物涂上树脂胶,垫布用熨压烫。待伤口粘合干透后,再用皮革补伤膏,用点补方法将伤残处填平。
4、真皮表面出现较大面积擦伤时,可以用补伤浆进行面补等。
所用材料:QC-ES除油清洁剂、QC-803强力清洁剂、皮革补伤膏、好威水性汽车皮革改色漆、QC-2500固化剂、QC-444固定剂、皮革美容精华乳
工艺流程:
第一步:清洁,用刷子沾QC-ES好威汽车内饰专用清洁剂对整个内饰真皮进行彻底的刷拭清洁,刷拭干净后用软棉布擦掉皮面上的残液,然后风干。
第二步:去膜,用刷子沾QC-803好威汽车内饰强力去膜剂对整个内饰真皮进行彻底的刷拭去膜,刷拭干净后用软棉布擦掉皮面上的残液,然后风干。
第三步:修补,在破损的地方用细砂纸打磨平整,然后用吹风机吹出粉尘;然后进行填补,用修补刀将QC-520好威汽车皮革修复补伤膏涂抹到破损的皮革上,涂抹是补伤膏会有突起和偏多等情况,用修补到一点点刮图平整,在破损的地方修补膏要稍微的突起2毫米左右,然后风干或用吹风机吹干。
第四步:翻新改色,把好威水性汽车皮革改色漆上下左右摇动1分钟后,把水性皮革改色漆倒入量杯进行调色,调好颜色后加入总量3%-5%的QC-2500汽车皮革翻新改色固化剂,然后搅拌均匀。把水性皮革改色漆混合物倒入洗干净的喷枪中,均匀地雾喷于真皮表面,然后风干;待干燥后,在重新均匀喷涂一遍以加强颜色的覆盖,再次风干。
第五步:固色,把QC-444汽车真皮翻新改色固定剂倒出,添加总量3%-5%的QC-2500汽车皮革翻新改色固化剂,然后搅拌均匀;把固定剂混合物倒入洗干净的喷漆中,均匀地雾喷于真皮表面,然后风干。
现在很多汽车美容店推出了一种真皮修复技术,通过真皮修复可以将真皮坐椅上出现的掉色、局部刮伤、龟裂、老化等现象最大限度地修复,而且经修、翻新或局部补伤后的皮革具有柔软的手感、自然柔和的光泽、能保证皮革的弹性及良好的透气性能。
这一技术主要是面向那些使用过2年以上的高档车,如常见的奔驰系列、宝马系列、凌志、保时捷卡宴等,另外是一些想要卖车的车主,因为皮面翻新后,车子的价格会变得更高。
一般车子上真皮使用的部位主要在坐椅、方向盘、车门板几个地方,也是使用率比较高的地方。真皮表面是色层、中间是皮层、底部是纤维层,而我们经常见到的真皮褪色一般指色层脱落,而修复也主要是针对色层进行修复。
1、皮座清洗
首先要用软刷子、半湿毛巾重点清洗需要修复、有皱纹的皮面,因为这里的灰尘很多,然后用干毛巾擦干。这样做的目的是为了保证皮革表面的清洁和干爽,后续材料才能更好地渗透皮层。
2、皮座打磨
接下来要用水砂纸打磨需要修复的表面,如果有一些龟裂的硬块要除掉,打磨后的皮屑用牙刷刷除。
3、软化补伤
在处理过后的皮革表面涂上皮革软化剂,用来软化发硬的真皮,然后再按照“填充———打磨———填充———打磨”的顺序涂上补伤膏,这一过程就和汽车喷漆里面的“补土”工序一样,只不过施工对象是皮面不是漆面。
