همچنین محصولات فرعی وجود دارد که پروفیل‌های اکسترود شده بر پایهٔ پلی‌وینیل کلراید سخت (یو پی‌وی‌سی) با مقاومت ضربهٔ بالا و سطح خارجی سفید هستند و در ساخت در و پنجره‌هایی که در دیوارهٔ خارجی ساختمان به‌کار می‌روند، استفاده می‌گردند.
Local keep prices could differ from Individuals exhibited. Products proven as offered are Ordinarily stocked but inventory degrees can not be confirmed.
This Web page is utilizing a stability company to safeguard alone from on the internet assaults. The action you merely executed triggered the security Alternative. There are lots of actions that would set off this block including distributing a particular phrase or phrase, a SQL command or malformed data.
اعتقاد بر این است که بیشتر محصولات وینیلی زمانی‌که به‌طور صحیح مصرف شوند عموماً بی‌ضررند هر چند تعدادی از افزودنی‌ها و نرم‌کننده‌ها از محصول وینیلی می‌توانند نشت کنند.
موارد استفادهٔ فراوانی برای پی‌وی‌سی شامل: وینیل سایدینگ، علامت مغناطیسی کارت‌ها، برش عمودی پنجره‌ها، صفحات گرامافون، لوله، لوله‌کشی، کانال و لوازم نصب‌کردنی، کیف‌های ارزان‌قیمت، پنجره‌های تاریک (بدون دید) و در شکل نرم آن برای لباس، اثاثیه یا لوازم داخلی نظیر پرده، کف‌سازی و ساختن سقف، پوستهٔ کابل‌های الکتریکی، توپ‌های بازی سبک‌وزن وجود دارد.
塩ビ樹脂溶液に皮膜を形成したいものを浸漬し、熱乾燥することで皮膜を形成できます。
PVC is largely made to be a rigid or unplasticized polymer (RPVC) or as a versatile plastic (uPVC). Versatile, plasticized or frequent PVC is softer and a lot more amenable to bending than uPVC because of the addition of plasticizers like phthalates including diisononyl phthalate or DINP.
PVC is created from petroleum. The manufacturing approach also takes advantage of sodium chloride. Recycled PVC is broken down into powder or compact chips Using the impurities taken out.
در ویکی‌انبار پرونده‌هایی دربارهٔ پلی‌وینیل کلراید موجود است.
Suspension Polymerization: This is the commonest method used in PVC production. It will involve the initiation of your response by absolutely free radicals, resulting in the polymerization in the vinyl chloride monomers suspended in drinking water.

Poly(vinyl chloride) (PVC) is an interesting matter for polymer ابواب وشبابيك pvc science investigation. Its features are heightened by its inherent structural faults ensuing from immediate producing (by no cost-radical polymerization), which also induce its thermal instability. Some of the fundamental restricting characteristics of PVC are actually advised to generally be alleviated by improved chemistry through PVC synthesis, Along with using both inorganic and organic and natural thermal stabilizers. The characteristics, characterization, modification, recycling, and different purposes of PVC are all examined With this paper combined with the earlier and newest investigate discoveries. It's been prompt that many of the elemental restricting Houses of PVC is often lessened by implementing both equally inorganic and organic and natural thermal stabilizers along side enhanced chemistry in the course of PVC manufacture.
Primary function of the project would be to aid the general public to know some interesting and essential details about chemical aspects and a lot of common supplies. We realize that the basics inside the resources science may also help people to comprehend a lot of prevalent complications.
The sleek area from the expanded PVC sheet implies you can easily incorporate any lamination, printing, or maybe individualized graphics to make it actually get noticed.
