| 橡胶脱模剂一般分为外用型和内用型两种。传统的脱模剂一般为外用型，即涂敷在模腔表面，习惯上也有称作隔离剂的，产品主要有滑石粉、云母粉、皂类、石蜡、聚四氟乙烯及硅油等，它们都有一定的脱模效果，但具有易留下模垢和痕迹、对模具有腐蚀作用、价格较昂贵等缺点。在众多的脱模剂品种中，氟、硅脱模剂因其脱模效果好、适合脱模的模材多，是近年来发展较快的两类脱模剂。 Rubber mold release agent is generally divided into two types: external use and internal use. The traditional release agent for external use, which is coated on the surface of the mold cavity, it is also customary is called isolation agent. The products mainly include talcum powder, mica powder, soap, paraffin, PTFE and silicone oil, they have demoulding effect, but is easy to leave traces, and scale model disadvantages of corrosion, the price is more expensive to die. Among the many kinds of mould release agent, fluorine and silicon release agent is the two kind of release agent in recent years because of its good demoulding effect and suitable mould release. 对脱模剂的主要要求是：有一定的热稳定性和化学惰性，不腐蚀模腔表面;在模腔表面下残留分解物;不影响产品色泽，但能赋予良好的外观、无毒;易于配制，使用方便。 The main requirements of release agent is: there are certain thermal and chemical stability, no corrosion cavity surface; residue decomposition in the surface of the mold cavity; does not affect the color of the product, but it can give a good appearance, easy preparation, convenient use and non-toxic. 橡胶脱模剂指用于防止橡胶产品与模具表面粘连，并能使之顺利出模而不致撕裂的一类物质。使用时将它喷或涂于模腔表面，以形成一层有效的隔离层。橡胶脱模剂的用途就在于此。 A rubber release agent is a substance used to prevent the adhesion of rubber products to the surface of the mold and to make it run smoothly without tearing. When in use, it is sprayed or applied to the surface of the mold cavity to form an effective insulating layer. The use of rubber release agents lies here. |
