氟系脱模剂
Fluorine demoulding agent
氟脱模剂继承了含氟材料的特点，能够显著降低固体的表面能，使其产生难浸润和不粘着性，不易与其他物质溶合，很好的解决了成品与模具之间的粘结问题，配制成脱模剂时，含氟化合物的用量极小。对热固性树脂、热塑性树脂和各种橡胶制件均适用，模制品表面光洁，二次加工性能优良，特别适合于精细电子零部件的脱模。售价一般在100-300元/kg，属于高档产品。
The fluorine release agent inherits the characteristics of the fluorine containing material, which can significantly reduce the surface energy of the solid, make it difficult to infiltrate and unstickiness, not easily dissolve with other substances, and solve the bond between the finished product and the mold, and the dosage of the fluorine containing compound is very small when it is prepared as a mold release agent. It is suitable for the thermosetting resin, thermoplastic resin and all kinds of rubber parts. The surface of the moulded products is bright and clean, and the two processing properties are excellent. It is especially suitable for the demoulding of fine electronic parts. The selling price is generally 100-300 yuan /kg, which belongs to the high-end product.
有机氟化物是最佳的脱模剂, 隔离性能好, 对模具污染小, 但价格较高。品种主要有:
Organic fluoride is the best release agent with good isolation performance, little pollution to mold, but high price. The main varieties are:
1) 聚四氟乙烯( 相对分子质量1800) ;
1) polytetrafluoroethylene (relative molecular mass 1800);
2) 氟树脂粉末( 低分子PTFE) ;
2) fluoro resin powder (low molecular PTFE);
3) 氟树脂涂料( PTFE, FEP, PFA) 。
3) fluoro resin coatings (PTFE, FEP, PFA).
