UV-ljus och temperatur anses vara de faktorer som svarar för den huvudsakliga nedbrytningen vid utomhusåldring av plast. I likhet med andra plaster bryts PVC ned av solljus. Den fotokemiska nedbrytningen accelereras vid höjd temperatur.

【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 most frequent use is in the development business, but Additionally it is utilized to manufacture indicators, in Health care purposes, and like a fiber for outfits.
The contents with the reaction vessel are pressurized and regularly mixed to maintain the suspension and make sure a uniform particle dimensions of your PVC resin. The reaction is exothermic and thus calls for cooling. As the quantity is lessened throughout the reaction (PVC is denser than VCM), drinking water is continuously included into the mixture to keep up the suspension.[9]
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。
型のなかにある空気を吸い取り、大気圧で型に押し付ける手法を「真空成形」、大気圧ではなく圧縮空気で金型に押し付ける手法を「圧空成形」と呼びます。
در مقابل حرارت و نور نسبتاً ناپایدار بوده و هیدروژن کلرید از آن خارج می‌شود. این ماده اثرات زیان‌بخشی روی خواص اشیاء دم دست (اجزای الکتریکی) علاوه بر اثرات فیزیولوژیکی بر جای می‌گذارد. پی‌وی‌سی پلاستیکی سخت است که به‌وسیلهٔ اضافه کردن روان‌کننده‌ها نرم و انعطاف‌پذیر می‌شود. بیشترین مورد استفادهٔ آن فتالیت است.

Expanded PVC board is often utilized for upholstery bases on boats, providing durability, waterproofing, and relieve of manipulation with typical woodworking equipment. It's also popular for crafting custom indicators and outdoor decor as a consequence of its flexibility in form and size. Study More Upholstery Bases
Poly(vinyl chloride) (PVC) continues to be a captivating subject matter for polymer science study. Its characteristics are heightened by its inherent structural faults ensuing from direct production (by no cost-radical polymerization), which also lead to its thermal instability. A number of the elemental limiting options of PVC happen to be recommended to get alleviated by enhanced chemistry in the course of PVC synthesis, Besides the use of equally inorganic and natural and organic thermal stabilizers. The qualities, characterization, modification, recycling, and several applications of PVC are all examined In this particular paper together with the past and most up-to-date investigate discoveries. It has been suggested that a number of the elemental limiting Homes of PVC could be lessened by implementing both inorganic and natural and pvc شبابيك organic thermal stabilizers together with enhanced chemistry during PVC manufacture.
Main objective of this project would be to support the public to learn some fascinating and crucial information regarding chemical components and plenty of widespread products. We realize that the basics inside the components science can assist people today to comprehend a lot of prevalent complications.
PVC’s multipurpose Attributes have resulted in its extensive use in several sectors. Some prevalent purposes include:
