塑料镶嵌是现代较流行的夹持金相试样的方法。但热镶法需要专用设备,而目前采用的冷镶法因填料固化时间长工作效率低。本文介绍一种快速冷镶法——“502”粘合剂镶嵌法。这种镶嵌法不需要复杂设备,操作简便,镶嵌速度快,效果可靠,极适合于丝箔材及各种形状不规则试样的镶嵌。一镶嵌用料 1 固化剂本实验用“502”粘合剂作固化剂。这种粘合剂的主要成分是α-氰基丙烯酸乙酯。它适用于除聚乙烯、聚丙烯、聚四氟乙烯以外的多种金属材料和非金属材料的粘结。基于这种粘结作用,加入适量的填料粉末,
Plastic inlaid is the more modern method of holding the metallographic sample. However, hot-set method requires special equipment, and the current cold-set method due to filler curing a long time low efficiency. This article describes a quick cold setting method - “502” adhesive setting method. This mosaic method does not require complex equipment, easy to operate, mosaic speed, reliable, very suitable for foil and a variety of irregular shaped specimen inlaid. An inlay 1 curing agent This experiment with “502 ” adhesive as a curing agent. The main component of this adhesive is ethyl α-cyanoacrylate. It applies to polyethylene, polypropylene, polytetrafluoroethylene other than a variety of metal materials and non-metallic materials bonding. Based on this bonding effect, adding an appropriate amount of filler powder,
