UV-ljus och temperatur anses vara de faktorer som svarar fileör den huvudsakliga nedbrytningen vid utomhusåldring av plast. I likhet med andra plaster bryts PVC ned av solljus. Den fotokemiska nedbrytningen accelereras vid höjd temperatur.
مخلوط‌کن‌های پودری: مخلوط کردن مواد مختلف توسط این مخلوط‌کننده‌ها انجام می‌گیرد. البته باید توجه کرد که در مخلوط کردن پایدارکننده‌ها، روان‌کننده‌ها، پیگمنت‌ها و… که باید مقدار آن‌ها نسبتاً کم باشد امکان ایجاد اشکالات عملی وجود دارد.
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。
Regardless of its environmental implications, initiatives are underway to manage PVC squander as a result of productive recycling mechanisms, pushing to a far more sustainable use of the priceless product.
PVC was synthesized in 1872 by German chemist Eugen Baumann just after prolonged investigation and experimentation.[twelve] The polymer appeared like a white strong inside a flask of vinyl chloride that were left on the shelf sheltered from sunlight for 4 weeks. Within the early 20th century, the Russian chemist Ivan Ostromislensky and Fritz Klatte of the German chemical enterprise Griesheim-Elektron both equally tried to use PVC in commercial goods, but challenges in processing the rigid, from time to time brittle polymer thwarted their efforts.
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。
型のなかにある空気を吸い取り、大気圧で型に押し付ける手法を「真空成形」、大気圧ではなく圧縮空気で金型に押し付ける手法を「圧空成形」と呼びます。
This makes it particularly straightforward to handle and operate with. So, even when You're not the strongest person, you gained’t discover it much too tough to shift it all over when producing advancements with your boat.
در ویکی‌انبار پرونده‌هایی دربارهٔ پلی‌وینیل کلراید موجود است.
Suspension Polymerization: This is often the most typical process used in PVC production. It requires the initiation of your response by free of charge radicals, leading to the polymerization on the vinyl chloride monomers suspended in water.

Poly(vinyl chloride) (PVC) continues to be a fascinating issue for polymer science investigate. Its features are heightened by its inherent structural faults resulting from direct production (by free of charge-radical polymerization), which also lead to its thermal instability. Some of the basic restricting functions of PVC have already been prompt to become alleviated by enhanced chemistry all through PVC synthesis, Together with the use of equally inorganic and organic thermal stabilizers. The qualities, characterization, modification, recycling, and many programs of PVC are all شيش حصير examined Within this paper combined with the earlier and most up-to-date investigate discoveries. It has been instructed that a number of the elemental limiting Homes of PVC can be lessened by implementing each inorganic and organic and natural thermal stabilizers along with enhanced chemistry for the duration of PVC manufacture.
Fantastic for personalization and if you want it to have an Formal logo or print on it to match up with the rest of the shade plan or décor within your boat.
The sleek floor with the expanded PVC sheet means you can easily incorporate any lamination, printing, as well as personalised graphics to make it really jump out.
