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.
ここでは塩ビの加工方法として代表的なものである、押出成形・カレンダー成形・射出成形・熱成形・ディッピング加工・コーティング加工を解説します。
Nonetheless, PVC is recyclable underneath certain circumstances. It could be mechanically recycled by grinding it into smaller pieces, which are then melted and remolded. In some instances, PVC can even be chemically recycled, breaking it down into its constituent monomers for reuse.
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 ensuing products is refined to make pure white PVC. It can be recycled around 7 periods. Its lifespan is about a hundred and forty yrs.
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。
聚氯乙烯可由乙烯、氯和催化劑經取代反應製成。由於其防火耐熱作用,聚氯乙烯被廣泛用於各行各業各式各樣產品:
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.
Adaptable PVC is usually used in construction as insulation on electrical wires or in flooring for properties, hospitals, universities, and other locations in which a sterile surroundings is essential. Rigid PVC can also be Utilized in design as pipe for plumbing and siding that is usually called
Suspension Polymerization: This is often the most common approach Utilized in PVC manufacturing. It requires the initiation in the reaction by totally free radicals, leading to the polymerization of the vinyl chloride monomers suspended in h2o.
Yes. An expanded PVC sheet continues to be created with inside and exterior works by using in mind. You could for that reason use it with self esteem on exterior components within your boat That could be subjected to rain, snow, sleet, and also other adverse weather conditions. Can expanded marine PVC board be bent to condition?(display/disguise)
Poly(vinyl chloride) (PVC) has been an interesting subject for polymer science investigate. Its qualities are heightened by its inherent structural faults resulting from immediate manufacturing (by absolutely free-radical polymerization), which also trigger its thermal instability. Several of the fundamental restricting features of PVC are already suggested being alleviated by improved chemistry for the duration of PVC synthesis, In combination with the use of both equally inorganic and natural thermal stabilizers. The features, characterization, modification, recycling, and numerous apps of PVC are all examined in this paper combined with the earlier and most recent analysis discoveries. It's been suggested that a number of the elemental limiting Homes of PVC is usually lessened by making use of both of those inorganic and natural and organic thermal stabilizers together with enhanced chemistry all through PVC manufacture.
Primary function of the project would be to aid the general public to master some fascinating and crucial specifics of chemical features ابواب وشبابيك pvc and lots of prevalent supplies. We know that the basics while in the elements science will help folks to comprehend many frequent complications.
