台化塑胶事业部原为化工第二事业部,早期是为配合台塑企业六轻计划上下游相关产业之发展而设立,当时负责芳香烃、系列之建厂筹划,由於六轻计划案厂址之滞延,乃决定由下游之聚(Polystyrene)先著手建厂,将产品导入市场,以利将来上游产品之产销。
PP has excellent chemical stability and is inert to most acids, bases, salts and oxidants. For example, it is stable in concentrated phosphoric acid, hydrochloric acid, 40% sulfuric acid and their salts at 100 ℃. Only a few strong oxidants such as fuming sulfuric acid can change them. PP is a non-polar compound, which is very stable to polar solvents, such as alcohol, , aldehyde, ketone and most carboxylic acids, but it is easy to dissolve or swell in some non-polar organic solvents
聚的生产工艺主要经历了溶剂法、溶液法,液相本体法(含液相气相组合式)和气相法几个发展阶段。世界上用于生产聚的工艺方法按类别划分主要有以下几大类:溶剂法、溶液法,液相本体法(含液相气相组合式)和气相法
The comprehensive properties of PP are better than that of PE. PP products are light in weight, good in toughness and good in chemical resistance. Disadvantages of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, easy to produce "copper damage", it has the phenomenon of t shrinkage, easy aging, brittle, easy deformation after demoulding. In daily life, the commonly used fresh-kee box is made of PP material. In order to prevent photoaging, it is necessary to add UV absorber into PP, which can transform the UV absorption of 290 ~ 400nm into non destructive long wavelength light. For the PP plastic products buried in the soil or used indoors in the dark, only the main and auxiliary antioxidants can be added, and the ultraviolet absorber is not needed. The shrinkage and crystallinity of PP are lower than that of PE. PP has a certain permeability to oxygen, carbon dioxide and water vapor. Compared with nylon PA and polyester PET, PP is much worse than nylon PA and polyester PET, but it is much worse for high barrier plastics such as PVDC and EVOH. But compared with other non plastic materials, its air tightness is quite good. The air tightness can be greatly improved by adding barrier materials or coating barrier plastics on the surface. PP is a non-polar polymer with good properties
PP分子中存在叔碳原子,在光和热的作用下极易断裂降解。未加稳定剂的PP在150℃下被加热半小时以上,或在阳光充足的地方曝晒12天就会明显变脆。未加稳定剂的PP 粉料在室内避光放置4 个月也会严重降解,散发出明显的酸味。在PP粉料造粒之前加入0.2%以上的抗氧剂可以有效地防止PP 在加工和使用过程中的降解老化。抗氧剂分为游离基链反应终止剂(也称主抗氧剂)和过氧化物分解剂(也称辅抗氧剂)两大类,主、辅两类抗氧剂的合理配合,将会发挥良好的协同效果。PP在离开口模后,如果是在空气中缓慢冷却,就会生成较大的晶粒,制品透明度低
