一、简要介绍该苯乙烯加工制造业的特点(一)苯乙烯性质及用途苯乙烯是一种有毒、易爆、对环境有严重危害的化学液体,不溶于水,溶于乙醇、乙醚中,暴露于空气中逐渐发生聚合及氧化。工业上是合成树脂、离子交换树脂及合成橡胶等的重要单体。(二)苯乙烯特性聚苯乙烯是指由苯乙烯单体经自由基缩聚反应合成的聚合物,英文名称为Polystyrene,简称PS。它是一种无色透明的热塑性塑料,具有高于摄氏100度的玻璃转化温度,因此经常被用来
First, a brief introduction of the characteristics of the styrene processing industry (A) the nature and use of styrene Styrene is a toxic, explosive, serious environmental hazards of chemical liquids, do not dissolve in water, soluble in ethanol, ether, Exposure to the air gradually occurs polymerization and oxidation. Industry is an important monomer for synthetic resins, ion exchange resins and synthetic rubbers. (B) Properties of Styrene Polystyrene is a polymer synthesized from styrene monomer by free radical polycondensation reaction, the English name is Polystyrene, referred to as PS. It is a colorless, transparent thermoplastic with a glass transition temperature above 100 degrees Celsius and is therefore often used
