硬脂酸钙与硬脂酸锌的区别!
来源:http://www.jnjrh.com 日期:2019-03-15 发布人:admin
  有很多用户对硬脂酸锌和硬脂酸钙混为一谈,其主要区别在于硬脂酸锌主要用作光滑剂,硬脂酸钙主要用于聚氯乙烯的热稳定剂,下面为您细致引见其区别:
  Many users mix zinc stearate with calcium stearate. The main difference is that zinc stearate is mainly used as smoothing agent, and calcium stearate is mainly used as thermal stabilizer for PVC. Here are the differences for you.
  硬脂酸钙与硬脂酸锌的区别
  The difference between calcium stearate and zinc stearate
  硬脂酸钙为平均细微的白色粉末。溶于甲苯、乙醇、苯和其他有机溶剂,不溶于水。加热至400℃时缓缓合成,可燃,遇强酸合成为硬脂酸和相应的钙盐。有吸水性,无毒。用作聚氯乙烯的热稳定剂和多种塑料加工的光滑剂,脱模剂等。在硬质制品中,与盐基性铅盐、铅皂配合可进步凝胶化速度。也用于食品包装、医疗用具等请求无毒的软质薄膜与用具。还可作聚乙烯,聚丙烯的卤素吸收剂,以消弭残留催化剂对颜色和稳定性的不良影响。在橡胶加工中作增塑剂,能使自然橡胶和全成橡胶软化,而对硫化简直无影响。亦用作聚烯烃纤维和模塑料的光滑剂,光滑脂的增厚剂,纺织品的防水剂,油漆的平光剂,制造塑料唱片时的增塑剂等。还用在铅笔芯消费及医药、香料工业中。
  Calcium stearate is an average fine white powder. Soluble in toluene, ethanol, benzene and other organic solvents, insoluble in water. It is slowly synthesized when heated to 400 C. It is flammable and synthesized into stearic acid and corresponding calcium salt when exposed to strong acid. Water absorption, non-toxic. It can be used as a heat stabilizer for PVC and a smoothing agent for various plastics processing, as well as a demoulding agent. In hard products, the combination of salt based lead and lead soap can improve the gelation rate. It is also used in food packaging, medical appliances and other non-toxic soft films and appliances. It can also be used as halogen absorbent of polyethylene and polypropylene to eliminate the harmful effect of residual catalyst on color and stability. In rubber processing, plasticizer can soften natural rubber and all rubber, but has no effect on vulcanization. It is also used as smoothing agent for polyolefin fibers and moulding plastics, thickener for smooth grease, waterproof agent for textiles, smoothing agent for paints, plasticizer for making plastic records, etc. It is also used in pencil lead consumption, medicine and perfume industry.

  硬脂酸锌是白色粉末,无毒、无污染、无风险特性,有吸附性,对皮肤有良好的粘附性。不溶于水、乙醇、乙醚,可溶于热乙醇、松节油、苯等有机溶剂。遇强酸合成成硬脂酸及其相应的盐类。在枯燥状况下有可燃性,燃点约为900℃。粉尘与空气的混合物遇明火有爆炸风险,爆炸下限为11.6g/m3。主要用作苯乙烯树脂、酚醛树脂、胺基树脂的光滑剂和脱模剂。同时在橡胶中还具有硫化活性剂,软化剂的功用。可用作PVC的无毒热稳定剂,抑止初期着色性及光滑性好,无硫化污染,但热稳定性能有限,构成的氯化锌对PVC有催化降解作用,普通不单独运用,多与钙皂、钡皂等稳定剂配合运用,主要用于软制品。
  Zinc stearate is a white powder, non-toxic, pollution-free, risk-free characteristics, adsorbability, good adhesion to the skin. Insoluble in water, ethanol, ether, soluble in hot ethanol, turpentine, benzene and other organic solvents. Stearic acid and its corresponding salts are synthesized from strong acid. It is flammable under dry conditions, and its ignition point is about 900 C. The mixture of dust and air has the risk of explosion when exposed to open fire. The lower limit of explosion is 11.6g/m3. It is mainly used as smoothing agent and demoulding agent for styrene resin, phenolic resin, amino resin. At the same time, it also has the function of vulcanizing activator and softener in rubber. It can be used as a non-toxic heat stabilizer for PVC. It has good colouring and smoothness in the initial stage and no sulphide pollution. However, its thermal stability is limited. The zinc chloride has catalytic degradation effect on PVC. It is not used alone. It is mostly used in combination with stabilizers such as calcium soap and barium soap. It is mainly used in soft products.
