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
2) sodium oleate. Mix 22 oleic acid with 100 portions of water and heat to near boiling. Then add 3 caustic soda slowly and stir until
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。
Saponification, control pH value of 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
4) fatty acid aluminum solution. The fat aluminum was dissolved in two chloroethane and mixed into 1% solution. Suitable for polyurethane products, 1 times,
重复用多次, 脱模效果好。
Repeated use of many times, the effect of demoulding is good.
5) 硬脂酸锌是透明塑料制品的脱模剂。
5) zinc stearate is a demoulding agent for transparent plastic products.
