In the process of handboard model processing, mistakes are always inevitable. PMMA is also commonly known as plexiglass or acrylic, because the material performance is very brittle and easy to crack, and there is no adhesive trace. Therefore, special attention should be paid in the process of processing. Once the cutting is too fast, the whole material may break, so the whole handboard will be scrapped. Therefore, PMMA handboard samples are also better than other handboards Dear, what should we do if there is a mistake? How to deal with it?

　　有一些手板模型出现较大的失误就不可补救了，只能报废，像透明件PMMA，PC等，因为透明工件是不许有粘接痕迹的，有一些工件却可以进行补救，挽回损失，工件为非透明件，像ABS，POM，PA等，一般都是针对塑胶件进行补救。补救的方法一般可用补救材料填在过切或错切的地方，更常用的补救材料是502胶水混合痱子粉或原子灰。

　　Some hand models have big mistakes that can't be remedied. They can only be scrapped, such as Transparent PMMA, PC, etc., because transparent workpieces are not allowed to have adhesive traces, while some workpieces can be remedied to recover losses. Workpieces are non transparent, such as ABS, POM, PA, etc., which are generally aimed at plastic parts. Generally, the remedy can be filled in the place of over cutting or wrong cutting, and the most commonly used remedy is 502 glue mixed with prickly ash or atomic ash.

　　取适量痱子粉加入502胶水调成稀糊状即可成为502胶水混合痱子粉，将调好的材料填入过切的地方待干后再补加工一下，原子灰为胶状粘稠物，需要配合催干剂才能凝固，进口原子灰较贵，国产原子灰较便宜。

　　Take a proper amount of prickly ash powder and add 502 glue to make it into a paste, then it will become 502 glue mixed prickly ash powder. Fill the prepared material in the over cut place, and then make up for processing after it is dry. The atomic ash is a glue like viscous substance, which needs to be combined with the drier to solidify. The price of imported atomic ash is more expensive, and the price of national atomic ash is cheaper.
