| 表面活性剂系脱模剂 Surfactants 表面活性剂脱模剂特点是隔离性能好, 但对模具有污染。主要有以下几类: The surfactant release agent is characterized by good isolation, but contamination of the mold. There are the following categories: 1)肥皂水。用肥皂配成一定量浓度的水溶液, 可作模具的润滑剂, 也可作为胶管的脱芯剂。 1) soapy water. A certain concentration of water solution is prepared with soap. It can be used as lubricant for mould and core breaker for rubber hose. 2)油酸钠。将22份油酸与100份水混合,加热至近沸, 再把3份苛性钠慢慢加入, 并搅拌至皂化, 控制pH值为7~ 9。使用时按1：1 的水稀释。用作外胎硫化脱模时, 需在200份上述溶液中加入2份甘油。 2) sodium oleate. Mix 22 oleic acid with 100 parts of water, heat it to near boiling, then add 3 caustic soda slowly and stir it to saponification, controlling pH value 7~ 9. When used, the water is diluted by 1:1. When the outer tire is used for vulcanization, 2 glycerin is added to 200 of the above solutions. 3) 甘油。可直接用作脱模剂或水胎润滑剂。 3) glycerin. It can be used directly as a demoulding agent or a water tire lubricant. 4) 脂肪酸铝溶液。将脂肪铝溶于二氯乙烷中配成1%溶液。适用于聚氨酯制品, 涂1次, 可重复用多次, 脱模效果好。 4) fatty acid aluminum solution. The fat aluminum was dissolved in two chloroethane and mixed into 1% solution. It is suitable for polyurethane products, coated 1 times, can be repeated many times, the mold release effect is good. |
