何本もある加熱したロールに、原料を通して圧延したあと、冷却ロールに通して厚みを調整し、材料を巻き取ることで、シートやフィルム状の塩ビを成形します。
ここでは塩ビの加工方法として代表的なものである、押出成形・カレンダー成形・射出成形・熱成形・ディッピング加工・コーティング加工を解説します。
Nevertheless, PVC is recyclable less than specified situations. It can be mechanically recycled by grinding it into smaller items, that are then melted and remolded. Occasionally, PVC can even be chemically recycled, breaking it down into its constituent monomers for reuse.
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 reaction vessel are pressurized and constantly blended to take care of the suspension and make sure a uniform particle dimension on the PVC resin. The reaction is exothermic and therefore calls for cooling. As the quantity is lessened during the reaction (PVC is denser than VCM), water is constantly 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.

Expanded PVC board is often used for upholstery bases on boats, furnishing longevity, waterproofing, and simplicity of manipulation with common woodworking equipment. It's also popular for crafting tailor made symptoms and outside decor because of its flexibility in form and measurement. Study Extra Upholstery Bases
Poly(vinyl chloride) (PVC) has actually been an interesting issue for polymer science analysis. Its properties are heightened by its inherent structural faults resulting from immediate manufacturing (by cost-free-radical polymerization), which also cause its thermal instability. A number of the elemental limiting capabilities of PVC happen to be instructed to be alleviated by enhanced chemistry all through PVC synthesis, Together with using the two inorganic and natural and organic thermal stabilizers. The traits, characterization, modification, recycling, and a variety of applications of PVC are all examined On this paper together with the past and most up-to-date investigate discoveries. It has been proposed that a number of the elemental limiting Homes شيش حصير of PVC is usually lessened by applying equally inorganic and natural and organic thermal stabilizers together with enhanced chemistry during PVC manufacture.
Most important objective of this job should be to assist the public to know some attention-grabbing and essential details about chemical aspects and a lot of typical components. We recognize that the basic principles during the materials science will help men and women to be aware of lots of common issues.
PVC’s functional Houses have triggered its large use in various sectors. Some typical programs contain:
