A lot of ongoing studies have expanded this chemistry, mostly with the chemical alterations of the polymeric compound. The chemical modification of PVC utilizing different products being an active modifying agent is described In this particular get the job done. The latter comprised grafting polymerizations, nucleophilic radicals, substitutions, PVC modifications, and removing or dehydrochlorination. This standpoint addresses the main PVC reactivity developments and supplies an outline of PVC functionalization though examining the environmental implications of PVC via the prism of chemical recycling. Via intensive ongoing research, this chemistry continues to be expanded, mostly from the chemical variations of the polymeric compound. To further improve its photo-balance Qualities, increase the purposes of poly(vinyl chloride) (PVC), and look into PVC-similar phenomena, various chemical modifications are actually introduced to PVC.
押出成形は、押出機のなかに溶融した原料を入れ、口金から押し出して成形する加工方法です。
Even so, PVC is recyclable below certain disorders. It could be mechanically recycled by grinding it into little parts, which might be then melted and remolded. In some instances, PVC may also be chemically recycled, breaking it down into its constituent monomers for reuse.
Its most typical use is ابواب وشبابيك pvc in the development industry, but Additionally it is utilized to manufacture signs, in healthcare purposes, and as being a fiber for apparel.
Expanded maritime PVC board or expanded PVC can be a form of PVC which has been expanded which has a special foaming agent to boost the thickness of the material when lessening its density. The foaming agent has been included in the design purposefully to reduce the amount of plastic is applied.
ポリ塩化ビニルの「ポリ」という言葉は、ポリマー（重合体）からきたもので、「たくさん」という意味があります。しかし、一般的に呼ばれている「塩ビ」は塩化ビニルではなく、ポリ塩化ビニルを指しているケースが多いので注意が必要です。
