ここでは塩ビの加工方法として代表的なものである、押出成形・カレンダー成形・射出成形・熱成形・ディッピング加工・コーティング加工を解説します。
【図解】チェッカープレート(縞板)の曲げ加工が通常より高くなる理由とは？
Its commonest use is in the construction marketplace, but It's also utilized to manufacture signs, in healthcare purposes, and like a fiber for outfits.
PVC was synthesized in 1872 by German chemist Eugen Baumann soon after extended investigation and experimentation.[twelve] The polymer appeared as being a white strong inside of a flask of vinyl chloride that were left on a shelf sheltered from sunlight for four weeks. Inside the early twentieth century, the Russian chemist Ivan Ostromislensky and Fritz Klatte with the German chemical enterprise Griesheim-Elektron each tried to use PVC in commercial goods, but troubles in processing the rigid, often brittle polymer thwarted their initiatives.

Automotive: PVC can be present in the automotive industry for pieces like dashboards, seat coverings, and insulation for wiring.
Poly(vinyl chloride) (PVC) continues to be a captivating subject for polymer science investigation. Its characteristics are heightened by its inherent structural faults ensuing from immediate producing (by totally free-radical polymerization), which also bring about its thermal instability. Some of the basic restricting functions of PVC are actually recommended being alleviated by improved chemistry through PVC synthesis, Along with the usage of each inorganic and organic and natural thermal stabilizers. The properties, characterization, modification, recycling, and different purposes of PVC are all examined in this paper combined with the earlier and most recent investigation discoveries. It's been advised that several of the fundamental limiting Houses of PVC can be lessened by making use of both equally inorganic and organic thermal stabilizers along with enhanced chemistry throughout PVC manufacture.
