Brief introduction of stabilizer
Broadly speaking, can increase the stability of the solution, colloid, solid, the mixture of chemicals are called stabilizers. It can slow down the reaction, maintain chemical balance, reduce surface tension, prevent light, thermal decomposition or oxidative decomposition and so on.
The broad source of chemical stabilizers is very broad, mainly based on the design of the design of the designer, can be flexible to use any chemicals to achieve product quality and stability purposes.
Narrowly speaking, mainly refers to the maintenance of high polymer plastic, rubber, synthetic fiber stability, to prevent its decomposition, aging reagents.
Industrial heat stabilizers commonly used mainly include lead salt, metal soap, organic tin, organic antimony, organic rare earth, pure organic compounds. It is estimated that China has a thermal stabilizer production capacity of 70,000 ta /, 2000 consumption of about 80,000 t / a.
China's lead salt development focus is to eliminate dust pollution, has taken relevant measures; organic tin in China's market consumption ratio is low; due to the high performance of the auxiliary stabilizer to promote poor work, the market is also the lack of cost-effective composite metal soap system ; Rare earth stabilizer is the development of China's heat stabilizer a force.
Global heat stabilizer consumption has more than 300,000 t / a, the United States represents the world's latest level of development of heat stabilizer, in the lead-free in the forefront of the world; Japan's heat stabilizer production of about 61,000 t / a, still the main lead salt; Western Europe heat stabilizer consumption of about 110,000 t / a.
