Stabilizers Prevent Colloidal Decomposition

The meaning of the stabilizer:

1, 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, Stabilizer can be flexible to use any chemicals to achieve the purpose of product quality and stability.

2, narrowly speaking, mainly refers to the maintenance of high polymer plastic, rubber, synthetic fiber stability, to prevent its decomposition, aging reagents.

Stabilizer is one of the important categories in plastic processing auxiliaries. The heat stabilizer is synchronized with the birth and development of PVC resin. It is mainly used in the processing of PVC resin. Therefore, the ratio of heat stabilizer to PVC resin and PVC is hard relationship.

PVC stabilizers are usually inorganic or organometallic compounds, and the term itself is meant to contain cations, or organic compounds, Stabilizer which are usually classified by chemical class. In general, inorganic and metal organic compounds are basic (or major) stabilizers, while organic compounds are secondary or auxiliary stabilizers.

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 heat 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; Stabilizer due to the high performance of the auxiliary stabilizer to promote the work of the poor, the market is also a 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.

What role does the stabilizer play?

Can stabilize the stability of the solution, colloid, solid, and mixture of chemicals called stabilizers. It can slow down the reaction, maintain chemical balance, Stabilizer reduce surface tension, prevent light, thermal decomposition or oxidative decomposition and so on. Generalized chemical stabilizer source Very broad, mainly based on the design of the design of the designer, you can use any flexible chemicals to achieve the purpose of product quality and stability.

Narrowly speaking, mainly refers to the maintenance of high polymer plastic, rubber, synthetic fiber stability, to prevent its decomposition, aging reagents.
