| 混凝土脱膜剂是为避免成形的工艺品黏附在磨具上，进而在工艺品与磨具中间释放一层层隔离膜，便于工艺品可以非常容易的从磨具中滑脱，一起确保工艺品工艺性能和磨具完好无缺。因此与树脂材料粘接力小的非旋光性或旋光性很弱的类别化学物质，能够做为脱膜剂，而且混凝土脱膜剂还要满足以下标准： The concrete film remover is to prevent the formed crafts from adhering to the abrasives, and then release a layer of isolation film between the crafts and the abrasives, so that the crafts can easily slide off from the abrasives, and together ensure the craft performance of the crafts and the integrity of the abrasives. Therefore, non optically active or optically weak chemical substances with small adhesion to resin materials can be used as a defoaming agent, and the concrete defoaming agent shall meet the following standards: 1、方便使用，破乳速度快； 1. Easy to use and fast demulsification; 2、不浸蚀磨具，不危害环氧树脂干固； 2. No erosion abrasives, no harm to the dry curing of epoxy resin; 3、破乳匀称，光洁，对环氧树脂的黏附力度不大； 3. The demulsification is well proportioned and smooth, and the adhesion to epoxy resin is not strong; 4、实际操作安全性，对人无有害物质； 4. Practical operation safety, no harmful substances to people; 5、价格低，来源于普遍，配置简易。 5. Low price, common source and simple configuration. |
