解放后,我国塑料工业如雨后春笋般地在蓬勃成长着。特別是近几年来,更是品种紛呈,面目一新,聚氯乙烯就是其中之一。現在大家看到五光十色的塑料制品,如:精致美观的手提包、新穎大方的雨衣,以至各式各样的儿童玩具、人造革皮鞋、塑料鞋底、塑料台布等,莫不是由它制成的。聚氯乙烯是什么? 聚氯乙烯,是微观世界的“巨人”,即高分子化合物之一。虽然組成它的分子还是肉眼看不見的,可是比一般常見的小分子,如水、酒精等要大几百、几千倍。
After the liberation, China’s plastics industry has mushroomed. In particular, in recent years, there have been many varieties and new features. PVC is one of them. Now we see colorful plastic products, such as: exquisite and beautiful handbags, innovative raincoats, as well as a variety of children’s toys, leather shoes, plastic soles, plastic tablecloths, etc., are made of it. What is PVC? PVC is the “giant” of the microcosm, that is, one of the macromolecular compounds. Although the molecules that make up it are invisible to the naked eye, they are hundreds or thousands of times larger than common small molecules such as water and alcohol.
