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。
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 of the reaction vessel are pressurized and constantly blended to maintain the suspension and make certain a uniform particle dimension on the PVC resin. The response is exothermic and thus needs cooling. As the amount is decreased in the course of the response (PVC is denser than VCM), h2o is regularly extra to your combination to maintain the suspension.[9]

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.

Automotive: PVC is usually located in the automotive field for pieces like dashboards, seat coverings, and insulation for wiring.
Poly(vinyl chloride) (PVC) has been an interesting subject for polymer science investigation. Its characteristics are heightened by its inherent structural faults ensuing from direct production (by totally free-radical polymerization), which also trigger its thermal instability. Several of the fundamental restricting features of PVC have already been recommended being alleviated by enhanced chemistry through PVC synthesis, Along with using both inorganic and organic and natural thermal stabilizers. The properties, characterization, modification, recycling, and different purposes of PVC are all examined Within this paper combined with the past and most up-to-date exploration discoveries. It has been proposed that some of the basic restricting properties of PVC could be lessened by implementing each inorganic and organic and natural thermal stabilizers at the side of improved chemistry for the duration of PVC manufacture.
Main goal of the project is usually to enable the general public to discover some appealing and important information about chemical factors and several popular materials. We understand that the fundamentals from the products science can help individuals to comprehend quite a few popular problems.
The smooth surface area in the expanded PVC sheet signifies you can certainly insert any lamination, printing, or maybe individualized شباك pvc graphics to really make it definitely stand out.
