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。
Its most common use is in the construction business, but It is additionally used to manufacture indicators, in Health care applications, and being a fiber for garments.
The contents with the response vessel are pressurized and regularly combined to keep up the suspension and assure a uniform particle size from the PVC resin. The reaction is exothermic and therefore calls for cooling. As the quantity is reduced throughout the reaction (PVC is denser than VCM), h2o is continually added for the combination to take care of 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) is a fascinating issue for polymer science exploration. Its features are heightened by its inherent structural faults resulting from immediate production (by totally free-radical polymerization), which also induce its thermal instability. Several of the fundamental limiting capabilities of PVC have already been suggested to generally be alleviated by enhanced chemistry in the course of PVC synthesis, Along with using the two inorganic and natural and organic thermal stabilizers. The attributes, characterization, modification, recycling, and numerous purposes of PVC are all examined In this particular paper along with the earlier and most up-to-date investigation discoveries. It has been prompt that several of the fundamental restricting properties of PVC might be lessened by applying both of those inorganic and natural thermal stabilizers at the side of enhanced chemistry throughout PVC manufacture.
Packaging: PVC’s adaptability and resistance to oil and grease make it a superb option for food stuff packaging.
Even though PVC has numerous beneficial works by using, What's more, it has سعر شبابيك pvc a big environmental affect. The creation and disposal of PVC can result in the release of harmful chemical compounds in the environment. Additionally, resulting from its toughness, PVC waste can persist within the environment for prolonged intervals.
