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.
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。
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。
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 contents from the reaction vessel are pressurized and frequently combined to maintain the suspension and assure a uniform particle measurement of the PVC resin. The response is exothermic and thus calls for cooling. As the volume is minimized through the response (PVC is denser than VCM), drinking water is frequently included into the mixture to take care of the suspension.[nine]

کارت‌های پی‌وی‌سی کارت‌هایی هستند که از پلاستیک فشرده تهیه شده و یکی از محصولات صنعت پتروشیمی هستند و مقاومت آن‌ها در مقابل گرما و سرما در مقایسه با کارت‌های کاغذی بسیار بالاتر بوده و دوام و ماندگاری آن نیز به دلیل نوع مواد به کار رفته در آن‌ها بیشتر است و بر اثر فشار یا ضربه آسیب نمی‌بینند.
金属加工業界の未来を支える人材確保のカギとは？取り組みと課題を徹底解説
If you’re having difficulty discovering the exact component you're looking for, the very best first step is to take a picture شيش حصير and give us a get in touch with.
Automotive: PVC is likewise present in the automotive business for parts like dashboards, seat coverings, and insulation for wiring.
Poly(vinyl chloride) (PVC) has actually been a captivating subject matter for polymer science exploration. Its properties are heightened by its inherent structural faults resulting from direct manufacturing (by totally free-radical polymerization), which also bring about its thermal instability. A few of the elemental limiting characteristics of PVC are actually advised to generally be alleviated by improved chemistry all through PVC synthesis, Together with using both equally inorganic and organic and natural thermal stabilizers. The attributes, characterization, modification, recycling, and several apps of PVC are all examined In this particular paper combined with the previous and most up-to-date analysis discoveries. It has been recommended that some of the fundamental limiting properties of PVC is usually lessened by implementing both of those inorganic and natural and organic thermal stabilizers along side improved chemistry throughout PVC manufacture.
Key intent of this venture is always to support the general public to learn some fascinating and crucial information regarding chemical things and a lot of common resources. We know that the basic principles in the supplies science will help men and women to grasp quite a few popular problems.
PVC’s functional Attributes have triggered its large use in various sectors. Some common applications consist of:
