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.
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。
Having said that, PVC is recyclable less than specified circumstances. It can be mechanically recycled by grinding it into compact items, which can be then melted and remolded. In some cases, PVC will also be chemically recycled, breaking it down into its constituent monomers for reuse.
Its most common use is in the construction sector, but It is additionally utilized to manufacture signals, in Health care applications, and like a fiber for outfits.
The contents of your reaction vessel are pressurized and regularly combined to take care of the suspension and make sure a uniform particle measurement with the PVC resin. The response is exothermic and thus demands cooling. As the amount is diminished in the response (PVC is denser than VCM), water is regularly additional on the combination to take care of the suspension.[9]

پلیوینیل کلراید بهوسیلهٔ پلیمریزاسیون مونومر وینیل کلراید شکل میگیرد. تولید تجارتی قسمت اعظم پیویسی عمدتاً از طریق بسپارش تعلیقی انجام میشود و از بسپارشهای تودهای و امولسیونی به میزان کمتر و از بسپارش محلولی به ندرت استفاده میشود. پلیوینیل کلراید از بلورینگی ناچیزی برخوردار بوده اما به علت زنجیرهای حجیم بسپار (نتیجهٔ استخلاف بزرگ سعر شبابيك pvc کلر) از استحکام و سختی برخوردار است. تی جی برای آن بالا و به میزان ۸۱ درجهٔ سانتیگراد است ولی میزان این تی جی آنقدر بالا نیست که فرایند با روشهای گوناگون را دچار مشکل کند.
Adaptable PVC is usually used in building as insulation on electrical wires or in flooring for properties, hospitals, universities, and other locations the place a sterile natural environment is essential. Rigid PVC is additionally Utilized in design as pipe for plumbing and siding that is usually called
Suspension Polymerization: That is the most typical strategy Utilized in PVC manufacturing. It entails the initiation of the response by no cost radicals, bringing about the polymerization on the vinyl chloride monomers suspended in drinking water.
Yes. An expanded PVC sheet has actually been created with interior and exterior works by using in mind. You can for that reason use it with self esteem on exterior factors within your boat Which may be exposed to rain, snow, sleet, together with other adverse weather conditions. Can expanded maritime PVC board be bent to shape?(present/disguise)

Premature ventricular contractions (PVCs) are additional heartbeats that start in among the heart's two lessen pumping chambers (ventricles). These excess beats disrupt the common coronary heart rhythm, often triggering a sensation of a fluttering or a skipped conquer during the upper body.
