در هر دو موقعیت پلیمر زمانی آشکار شد که جامد سفید رنگ داخل فلاسک وینیل کلراید در معرض نور آفتاب قرار گرفت.

Not simply does this decrease the cost and number of non-recyclable resources, but What's more, it aids to reduce its body weight way too. Because of its temperature resistance and also other Positive aspects, it's a standard content used for boat sections.
Its most common use is in the construction marketplace, but It's also accustomed to manufacture signals, in healthcare apps, and to be a fiber for apparel.
The contents of the reaction vessel are pressurized and constantly blended to maintain the suspension and make sure a uniform particle measurement on the PVC resin. The response is exothermic and therefore necessitates cooling. As the volume is decreased through the response (PVC is denser than VCM), drinking water is frequently included towards the mixture to keep up the suspension.[nine]
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.

Allt eftersom biltillverkarna har sökt efter lättare substance har fler och fler detaljer i bilen blivit tillverkade i plast.

Poly(vinyl chloride) (PVC) has actually been an interesting subject for polymer science investigation. Its traits شباك pvc are heightened by its inherent structural faults ensuing from direct producing (by totally free-radical polymerization), which also bring about its thermal instability. A number of the elemental restricting options of PVC have already been suggested being alleviated by improved chemistry for the duration of PVC synthesis, in addition to the usage of both of those inorganic and organic and natural thermal stabilizers. The characteristics, characterization, modification, recycling, and different programs of PVC are all examined With this paper along with the previous and most recent exploration discoveries. It has been instructed that some of the basic limiting Houses of PVC could be lessened by implementing both inorganic and organic and natural thermal stabilizers in conjunction with improved chemistry all through PVC manufacture.
Packaging: PVC’s versatility and resistance to oil and grease ensure it is a wonderful choice for foods packaging.
Despite the fact that PVC has a lot of helpful makes use of, Additionally, it has a significant environmental impact. The output and disposal of PVC may result in the discharge of unsafe chemical compounds to the surroundings. In addition, due to its durability, PVC squander can persist from the setting for extended periods.
