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。
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。
قالب‌گیری به روش تزریقی، اکستروژن و شکل‌دادن حرارتی نیز از روش‌های دیگر هستند.
سوزاندن، تولید و آزادسازی مقدار زیادی دی‌اکسین است و اجزای تشکیل‌دهندهٔ کلرین که محیط زیست را می‌آلاید.
The molecular composition of PVC is made of a lengthy-chain polymer with repeating vinyl chloride models. Every single vinyl chloride unit includes 1 carbon atom double-bonded to a chlorine atom and one-bonded to 2 hydrogen atoms.

To present you with by far the most appropriate and beneficial data, and understand which details is useful, we may perhaps Incorporate your email and website use facts with other facts We've about you. Should you be a Mayo Clinic affected individual, this could contain secured health details.
Adaptable PVC is usually Employed in construction as insulation on electrical wires or in flooring for homes, hospitals, educational institutions, together with other locations where a sterile atmosphere is critical. Rigid PVC can be Employed in design as pipe for plumbing and siding that is usually called
کارت‌های پی‌وی‌سی جنس مقاوم و قابل انعطافی دارند و به دلیل ماندگاری زیادی که دارند می‌توانند برای چاپ کارت‌های هوشمند و کارت بانکی و اعتباری و همچنین برای چاپ کارت پرسنلی و شناسایی مورد استفاده قرار بگیرند. از دیگر مزایای کارت‌های پی‌وی‌سی می‌توان به قابلیت ضدآب بودن آن اشاره کرد که در برابر رطوبت نیز مقاوم هستند؛ و همچنین پلاستیک مورد استفاده در تولید و چاپ کارت پی‌وی‌سی امکان بازیافت و استفادهٔ دوباره را دارد و به این ترتیب با استفاده از کارت‌های پی‌وی‌سی به جای کاغذ و مقوا از آسیب به محیط زیست هم پیشگیری می‌شود.

Poly(vinyl chloride) (PVC) has become a fascinating matter for polymer science investigation. Its characteristics are heightened by its inherent structural شيش حصير faults resulting from immediate manufacturing (by cost-free-radical polymerization), which also cause its thermal instability. A number of the fundamental restricting options of PVC are already suggested being alleviated by improved chemistry in the course of PVC synthesis, In combination with the usage of both equally inorganic and organic thermal stabilizers. The attributes, characterization, modification, recycling, and various apps of PVC are all examined During this paper combined with the past and most up-to-date investigate discoveries. It has been prompt that a few of the elemental limiting Houses of PVC can be lessened by implementing both of those inorganic and natural and organic thermal stabilizers in conjunction with improved chemistry during PVC manufacture.
Following, the alerts get there in a cluster of cells known as the atrioventricular (AV) node, where they slow down. This slight delay permits the ventricles to fill with blood. Once the electrical signals reach the ventricles, the chambers agreement and pump blood on the lungs or to the remainder of the overall body.
