何本もある加熱したロールに、原料を通して圧延したあと、冷却ロールに通して厚みを調整し、材料を巻き取ることで、シートやフィルム状の塩ビを成形します。
PVC output will involve a course of action often known as polymerization, whereby monomers of vinyl chloride are chemically bonded to sort a polymer chain. The two principal kinds of polymerization used are suspension polymerization and emulsion polymerization.
Health care: The Health care business employs PVC in a number of clinical equipment which include blood bags, tubing, and IV bags. Its ability to be sterilized makes it ideal for these programs.
Regardless of its environmental implications, initiatives are underway to deal with PVC squander by means of successful recycling mechanisms, pushing to a more sustainable use of this a must have material.
PVC was synthesized in 1872 by German chemist Eugen Baumann just after extended investigation and experimentation.[twelve] The polymer appeared being a white stable inside of a flask of vinyl chloride that were remaining with a shelf sheltered from daylight for 4 weeks. In the early 20th century, the Russian chemist Ivan Ostromislensky and Fritz Klatte from the German chemical شيش حصير organization Griesheim-Elektron equally tried to implement PVC in professional products and solutions, but challenges in processing the rigid, sometimes brittle polymer thwarted their efforts.
The molecular composition of PVC contains an extended-chain polymer with repeating vinyl chloride units. Each vinyl chloride device incorporates just one carbon atom double-bonded into a chlorine atom and solitary-bonded to two hydrogen atoms.
