UV-ljus och temperatur anses vara de faktorer som svarar fileör den huvudsakliga nedbrytningen vid utomhusåldring av plast. I likhet med andra plaster bryts PVC ned av solljus. Den fotokemiska nedbrytningen accelereras vid höjd temperatur.
PVC output consists of a course of action often known as polymerization, whereby monomers of vinyl chloride are chemically bonded to kind a polymer chain. The two major forms of polymerization employed are suspension polymerization and emulsion polymerization.
Vid temperaturer upp until 60°C är styv PVC resistent mot de flesta oorganiska vätskor inklusive moderat koncentrerade syror samt alkali och icke-oxiderande saltlösningar i alla koncentrationer.
Have in mind, PVC board just isn't especially solid on its own, so it will require a base or assist method to forestall bending or breaking.
سوزاندن، تولید و آزادسازی مقدار زیادی دی‌اکسین است و اجزای تشکیل‌دهندهٔ کلرین که محیط زیست را می‌آلاید.
پلی‌وینیل کلراید به‌طور اتفاقی در دو موقعیت کوچک در قرن ۱۹ کشف شد. نخستین بار در سال ۱۸۳۵ به‌وسیله هنری ویکتور رگنالت و در ۱۸۷۲ به‌وسیله اوگن بومان.
Furthermore, it has good electrical insulation Attributes, which makes it an acceptable content for wiring and cable programs.
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.

Automotive: PVC is likewise present in the automotive market for parts like dashboards, seat coverings, and insulation for wiring.
Poly(vinyl chloride) (PVC) has been an interesting issue for polymer science analysis. Its qualities are heightened by its inherent structural faults ensuing from direct manufacturing (by totally free-radical polymerization), which also induce its thermal instability. Several of the fundamental limiting options of PVC happen to be advised to generally be alleviated by improved chemistry in the course of PVC synthesis, Besides using the two inorganic and organic thermal stabilizers. The characteristics, characterization, modification, recycling, and different purposes of PVC are all examined On this paper combined with the pvc شبابيك earlier and most recent study discoveries. It's been prompt that many of the fundamental restricting Houses of PVC can be lessened by making use of both of those inorganic and organic and natural thermal stabilizers along side enhanced chemistry all through PVC manufacture.
Main reason of the undertaking would be to help the general public to know some exciting and crucial information about chemical elements and a lot of widespread components. We realize that the basic principles from the components science might help people to be familiar with quite a few frequent issues.
PVC’s functional Qualities have led to its huge use in a variety of sectors. Some typical applications include things like:
