一、前言炭黑pH值对橡胶的物理性能有一定的影响,pH值的大小可促进或延缓橡胶的硫化速度,pH值高,将加快胶料的硫化速度;pH值低,将会延缓橡胶的硫化速度。一般来说,槽法炭黑pH值呈弱酸性,能延缓胶料的硫化;炉法炭黑pH值呈碱性,将促进胶料的硫化。胶料的硫化速度将影响轮胎厂的经济效益。在现有能源紧张、效益第一的年代,提高硫化胶的硫化速度,对提高轮胎行业的经济效益是非常重要的。
Preface Carbon black pH value of the physical properties of rubber have a certain impact, the size of the pH value can promote or delay the vulcanization speed of rubber, high pH value, will speed up the vulcanization speed rubber; low pH, will delay the rubber The curing speed. In general, the trough carbon black pH is weakly acidic, can delay the vulcanization of rubber; furnace black pH is alkaline, will promote the vulcanization of rubber. Rubber compound curing speed will affect the economic benefits of tire factory. In the current energy shortage and efficiency of the first era, to improve the cure rate of vulcanized rubber, to improve the economic efficiency of the tire industry is very important.
