| 聚氨脂(PU)与其它材料具有优异的粘结性能。这种性质在泡沫体模塑中是不利的。在模塑聚氨酯泡沫、浇注聚氨酯弹性体及目前世界上发展迅速的反应注射成型(RIM)等制品的生产中。为了迅速顺利地从模具中取出制品， 必须使用脱模剂。在聚氨酯成型加工中， 为获得表面光洁的制品而使用脱模剂。 Polyurethane (PU) has excellent adhesion with other materials. This property is disadvantageous in foam molding. In the production of molded polyurethane foam, cast polyurethane elastomer and the rapid development of reaction injection molding (RIM) products in the world. In order to remove the product from the mold quickly and smoothly, the release agent must be used. In the process of polyurethane molding, mold release agent is used to obtain products with smooth surface. 较为理想的脱模剂应具有较好的热稳定性和化学稳定性， 不腐蚀模具， 在模具表面不残存分解物；应能给予制品良好的外观， 不影响制品的色泽、粘合性、受漆能力等；应要求尽可能少的模具清理时间；应无毒， 安全， 便于操作；应成本较低。 The ideal mold release agent should have good thermal and chemical stability, not corrode the mold, and do not retain decomposition products on the mold surface; it should be able to give a good appearance of the products, without affecting the color, adhesiveness and painting ability of the products; it should require as little cleaning time of the mold as possible; it should be non-toxic, safe, easy to operate; it should be low cost. |
