永磁筒式弱磁选机磁块与磁极板粘结,一般采用环氧树脂。但实践表明,它有明显的冷脆性,特别是冬天,必须将室温提高,才能保证粘结质量。我厂学习兄弟单位经验,经过多次试验,添加了胺类促进剂,摸索出一组新配方,取得很好效果。配方用量(克)多计聚氨酷粘结剂150 100 甲组份100 乙组份50氧化铝粉 Permanent magnetic drum weak magnetic separator magnets and magnetic plate bonding, the general use of epoxy resin. However, practice shows that it has obvious cold and brittleness, especially in winter, the room temperature must be increased in order to ensure the bonding quality. I plant brothers learn from the experience of the unit, after many tests, added amine accelerators, worked out a new formula, and achieved good results. Formula dosage (g) Polycure Polyurethane 150 150 Part A 100 Part B 50 Alumina powder
