Quite a few ongoing experiments have expanded this chemistry, mostly from the chemical changes of the polymeric compound. The chemical modification of PVC employing different elements being an Lively 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 principle PVC reactivity trends and presents an summary of PVC functionalization even though analyzing the environmental implications of PVC by way of the prism of chemical recycling. As a result of substantial ongoing investigate, this chemistry has actually been expanded, mostly in the chemical adjustments of this polymeric compound. To boost its Image-balance Qualities, develop the applications of poly(vinyl chloride) (PVC), and examine PVC-linked phenomena, many chemical modifications are introduced to PVC.

Nevertheless, PVC is recyclable under particular conditions. It could be mechanically recycled by grinding it into tiny pieces, which happen to be then melted and remolded. Occasionally, PVC can 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。

PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimentation.[12] The polymer appeared as being a white sound within a flask of vinyl chloride that had been left over a shelf sheltered from sunlight for four months. In the early twentieth century, the Russian chemist Ivan Ostromislensky and Fritz Klatte with the German chemical business Griesheim-Elektron equally attempted to make use of PVC in industrial items, but challenges in processing the rigid, sometimes brittle polymer thwarted their efforts.

問い合わせが多い工場の秘密!他社と差をつける営業テクニックやよくあるミスとは

با وجود این‌که محصولات پی‌وی‌سی تولید شده‌اند یکی از بیشترین مواد سمی شیمیایی به نام دی‌اکسین را منتشر می‌کنند. محصولات پی‌وی‌سی زمانی‌که می‌سوزند یا دفن می‌شوند می‌توانند مضرانه نفوذ کنند.

در ویکی‌انبار پرونده‌هایی دربارهٔ پلی‌وینیل کلراید موجود است.

کارت‌های پی‌وی‌سی جنس مقاوم و قابل انعطافی دارند و به دلیل ماندگاری زیادی که دارند می‌توانند برای چاپ کارت‌های هوشمند و کارت بانکی و اعتباری و همچنین برای چاپ کارت پرسنلی و شناسایی مورد استفاده قرار بگیرند. از دیگر مزایای کارت‌های پی‌وی‌سی می‌توان به قابلیت ضدآب بودن آن اشاره کرد که در برابر رطوبت نیز مقاوم هستند؛ و همچنین پلاستیک مورد استفاده در تولید و چاپ کارت پی‌وی‌سی امکان بازیافت و استفادهٔ دوباره را دارد و به این ترتیب با استفاده از کارت‌های پی‌وی‌سی به جای کاغذ و مقوا از آسیب به محیط زیست هم پیشگیری می‌شود.

Poly(vinyl chloride) (PVC) has long been an interesting issue for polymer science analysis. Its properties are heightened by its inherent structural faults resulting from immediate manufacturing (by absolutely free-radical polymerization), which also trigger its thermal instability. Several of the fundamental limiting options of PVC have already been prompt to become alleviated by enhanced chemistry during PVC synthesis, Together with using the two inorganic and natural and organic thermal stabilizers. The traits, characterization, modification, recycling, and several applications of PVC are all examined In this particular paper pvc شبابيك together with the previous and newest study discoveries. It has been instructed that a few of the fundamental limiting Attributes of PVC may be lessened by making use of both of those inorganic and natural thermal stabilizers along with improved chemistry for the duration of PVC manufacture.

カレンダー成形は、シートやフィルムなどの平らな製品を成形するのに活用される加工方法です。

The carbon-chlorine bonds in the vinyl chloride models give PVC its unique Homes, including resistance to environmental elements and electrical insulation.
