Several ongoing reports have expanded this chemistry, generally through the chemical modifications of this polymeric material. The chemical modification of PVC employing several products as an active modifying agent is described Within this perform. The latter comprised grafting polymerizations, nucleophilic radicals, substitutions, PVC modifications, and elimination or dehydrochlorination. This standpoint addresses the main PVC reactivity developments and gives an outline of PVC functionalization when inspecting the environmental implications of PVC via the prism of chemical recycling. By means of comprehensive ongoing exploration, this chemistry has long been expanded, primarily through the chemical modifications of this polymeric substance. To enhance its Photograph-security Houses, extend the applications of poly(vinyl chloride) (PVC), and investigate PVC-relevant phenomena, a lot of chemical modifications have already been launched to PVC.
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。
Nonetheless, PVC is recyclable under sure problems. It may be mechanically recycled by grinding it into small parts, which can be then melted and remolded. In some cases, PVC will also be chemically recycled, breaking it down into its constituent monomers for reuse.
立体的な製品を成形可能で、押し出し成形よりも複雑な形状を生産できます。製品のサイズも小さいものから大きなものまで対応が可能です。
About 50 percent of the whole world's PVC manufacturing ability is in China, Regardless of the closure of numerous Chinese PVC crops due to problems complying with environmental rules and weak capacities of scale.
پلی‌وینیل کلراید به‌طور اتفاقی در دو موقعیت کوچک شيش حصير در قرن ۱۹ کشف شد. نخستین بار در سال ۱۸۳۵ به‌وسیله هنری ویکتور رگنالت و در ۱۸۷۲ به‌وسیله اوگن بومان.
In addition, it has good electrical insulation Houses, making it an acceptable content for wiring and cable applications.

Pure polyvinyl chloride is usually a white, brittle good generally sent as powder or pellets. It really is insoluble in alcohol but somewhat soluble in tetrahydrofuran.
