パイプなどのように、断面形状がシンプルな形状の製品を作るのに適しています。口金の形状を変えることで、押し出される製品も形を変えられます。
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。
The contents from the response vessel are pressurized and continually combined to take care of the suspension and make certain a uniform particle sizing of your PVC resin. The reaction is exothermic and so demands cooling. As the quantity is lowered over the reaction (PVC is denser than VCM), drinking water is continually added on the combination to maintain the suspension.[nine]

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.

Poly(vinyl chloride) (PVC) has actually been an interesting subject for polymer science investigate. Its features are heightened by its inherent structural faults ensuing from immediate manufacturing (by no cost-radical polymerization), which also trigger its thermal instability. A number of the fundamental restricting characteristics of PVC happen to be proposed to generally be alleviated by improved chemistry all through PVC synthesis, As well as using both of those inorganic and natural thermal stabilizers. The qualities, characterization, modification, recycling, and various apps of PVC are all examined On this paper together with the earlier and most up-to-date investigate discoveries. It has been proposed that some of the basic restricting Qualities of PVC is often lessened by applying equally inorganic and natural thermal stabilizers along side improved chemistry in the course of PVC manufacture.
Packaging: PVC’s adaptability and resistance to oil and grease allow it to be an excellent choice for foodstuff packaging.
While PVC has a lot of useful makes use of, In addition it has a substantial environmental influence. The production and disposal of PVC ابواب وشبابيك pvc may lead to the discharge of hazardous chemical substances into the ecosystem. Additionally, because of its durability, PVC squander can persist while in the surroundings for extended durations.
