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.
کلندرها: جهت تهیهٔ ورقههای طویل از کائوچو و ترموپلاستیکها رزین نرم شده را بین دو یا چند سیلندر عبور میدهند.
And also its structural integrity, Additionally, it benefits from owning larger colour-fastness when compared with different PVC foam items accessible on the market.

Expanded maritime PVC board or expanded PVC is usually a style of PVC that has been expanded by using a special foaming agent to improve the thickness of the fabric although cutting down its density. The foaming agent has been A part of the look purposefully to cut back the amount of plastic is used.
ポリ塩化ビニルの「ポリ」という言葉は、ポリマー(重合体)からきたもので、「たくさん」という意味があります。しかし、一般的に呼ばれている「塩ビ」は塩化ビニルではなく、ポリ塩化ビニルを指しているケースが多いので注意が必要です。
PVC features a list of special properties that add to its wide range of apps. Among the key traits is its longevity and resistance to environmental stressors including humidity, chemical substances, and ultraviolet radiation.
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 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.
Selected Way of life alternatives and wellbeing conditions may well make anyone more prone to produce untimely ventricular contractions (PVCs).
Pure polyvinyl chloride is usually a white, brittle sound commonly shipped as powder or pellets. It truly is insoluble in alcohol but somewhat soluble in tetrahydrofuran.
One of many to start with stuff you will discover about the maritime PVC board that We've got in stock below at Boat Outfitters is The truth that it is very lightweight.
Poly(vinyl chloride) (PVC) has long been a fascinating subject matter for polymer science study. Its features are heightened by its inherent structural faults resulting from immediate manufacturing (by cost-free-radical polymerization), which also induce its thermal instability. A few of the elemental limiting capabilities of PVC happen to be proposed to be alleviated by improved chemistry through PVC synthesis, As well as using each inorganic and organic and natural thermal stabilizers. The qualities, characterization, modification, recycling, and many programs of PVC are all examined With this paper along with the previous and newest research discoveries. It has been instructed that some of the basic restricting properties of PVC might be lessened by implementing each inorganic and organic and natural thermal stabilizers in conjunction with improved chemistry in the course of PVC manufacture.
Packaging: شباك pvc PVC’s versatility and resistance to oil and grease help it become a wonderful choice for foods packaging.
PVC’s flexible Qualities have resulted in its vast use in a variety of sectors. Some prevalent purposes involve:
