PVC manufacturing entails a process known as polymerization, whereby monomers of vinyl chloride are chemically bonded to form a polymer chain. The 2 key varieties of polymerization employed are suspension polymerization and emulsion polymerization.
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 in the response vessel are pressurized and frequently mixed to maintain the suspension and make certain a uniform particle dimensions with the PVC resin. The response is exothermic and thus demands cooling. As the quantity is lowered in the course of the response (PVC is denser than VCM), water is constantly extra to the mixture 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。
کارت‌های پی‌وی‌سی کارت‌هایی هستند که از پلاستیک فشرده تهیه شده و یکی از محصولات صنعت پتروشیمی هستند و مقاومت آن‌ها در مقابل گرما و سرما در مقایسه با کارت‌های کاغذی بسیار بالاتر بوده و دوام و ماندگاری آن نیز به دلیل نوع مواد به کار رفته در آن‌ها بیشتر است و بر اثر فشار یا ضربه آسیب نمی‌بینند.

Automotive: PVC can also be found in the automotive field for sections like dashboards, seat coverings, and insulation for wiring.
Poly(vinyl chloride) (PVC) has actually been a fascinating matter for polymer science research. Its attributes are heightened by its inherent structural faults resulting from immediate producing (by cost-free-radical polymerization), which also cause its thermal instability. Several of the fundamental limiting options of PVC have already been prompt to become alleviated by enhanced chemistry throughout PVC synthesis, Together with the use of both inorganic and organic and natural thermal stabilizers. The characteristics, characterization, modification, recycling, and a variety of purposes of PVC are all examined On this paper together with the past and most up-to-date investigate discoveries. It has been instructed that some of the basic restricting Qualities of PVC might be lessened by implementing the two inorganic and natural and organic thermal stabilizers in conjunction with enhanced chemistry all through PVC manufacture.
Primary goal of the job is to assist the public to know some attention-grabbing and important details about chemical aspects and several popular materials. We understand that the fundamentals while pvc شبابيك in the elements science can help individuals to be familiar with a lot of popular troubles.
The sleek surface with the expanded PVC sheet implies you can certainly increase any lamination, printing, as well as customized graphics to make it truly stick out.
