A lot of ongoing scientific tests have expanded this chemistry, largely throughout the chemical adjustments of this polymeric material. The chemical modification of PVC employing various products being an Lively modifying agent is explained With this operate. The latter comprised grafting polymerizations, nucleophilic radicals, substitutions, PVC modifications, and elimination or dehydrochlorination. This viewpoint addresses the primary PVC reactivity traits and presents an outline of PVC functionalization even though analyzing the environmental implications of PVC via the prism of chemical recycling. Through considerable ongoing exploration, this chemistry has become expanded, largely throughout the chemical adjustments of this polymeric substance. To further improve its photo-steadiness Houses, increase the applications of poly(vinyl chloride) (PVC), and look into PVC-linked phenomena, a lot of chemical modifications are already 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。
Along with its structural integrity, In addition, it Advantages from having bigger shade-fastness in comparison with option PVC foam products out there available.
Its most common use is in the development field, but It is additionally used to manufacture indications, in Health care applications, and like a fiber for outfits.
PVC was synthesized in 1872 by German chemist Eugen Baumann just after prolonged investigation and experimentation.[twelve] The polymer appeared as a white strong inside a flask of vinyl chloride that had been left on the shelf sheltered from daylight for 4 weeks. Inside the early twentieth century, the Russian chemist Ivan Ostromislensky and Fritz Klatte on the German chemical corporation Griesheim-Elektron both of those tried to employ PVC in commercial products, but issues in processing the rigid, occasionally brittle polymer thwarted their attempts.
The molecular framework of PVC is made up of a protracted-chain polymer with repeating vinyl chloride models. Each individual vinyl chloride device is made up of a single carbon atom double-bonded to a chlorine atom and single-bonded to 2 hydrogen atoms.
聚氯乙烯可由乙烯、氯和催化劑經取代反應製成。由於其防火耐熱作用，聚氯乙烯被廣泛用於各行各業各式各樣產品：
پلی‌وینیل کلراید به‌وسیلهٔ پلیمریزاسیون مونومر وینیل کلراید شکل می‌گیرد. تولید تجارتی قسمت اعظم پی‌وی‌سی عمدتاً از طریق بسپارش تعلیقی انجام می‌شود و از بسپارش‌های توده‌ای و امولسیونی به میزان کمتر شباك pvc و از بسپارش محلولی به ندرت استفاده می‌شود. پلی‌وینیل کلراید از بلورینگی ناچیزی برخوردار بوده اما به علت زنجیرهای حجیم بسپار (نتیجهٔ استخلاف بزرگ کلر) از استحکام و سختی برخوردار است. تی جی برای آن بالا و به میزان ۸۱ درجهٔ سانتی‌گراد است ولی میزان این تی جی آن‌قدر بالا نیست که فرایند با روش‌های گوناگون را دچار مشکل کند.
Sure Way of life alternatives and health and fitness situations may well make an individual much more likely to acquire untimely ventricular contractions (PVCs).

حتی با وجود این‌که پی‌وی‌سی اسباب‌بازی‌های نرم برای نوزادان برای سال‌ها ساخته شده‌است، این نگرانی وجود دارد که این افزودنی‌ها از اسباب‌بازی‌های نرم به دهان کودکانی که آن را به دهان می‌برند نشت کند.
The carbon-chlorine bonds within the vinyl chloride units give PVC its distinctive Attributes, for instance resistance to environmental components and electrical insulation.
