UV-ljus och temperatur anses vara de faktorer som svarar för den huvudsakliga nedbrytningen vid utomhusåldring av plast. I likhet med andra plaster bryts PVC ned av solljus. Den fotokemiska nedbrytningen accelereras vid höjd temperatur.
دستگاههای ژلیفیکاسیون: معمولاً از نوع ماشینهای تهیهٔ ورقه هستند.
On the other hand, PVC is recyclable beneath certain disorders. It could be mechanically recycled by grinding it into little pieces, which happen to be then melted and remolded. Sometimes, PVC may also be chemically recycled, breaking it down into its constituent monomers for reuse.
قالبگیری به روش تزریقی، اکستروژن و شکلدادن حرارتی نیز از روشهای دیگر هستند.
Expanded marine PVC board or expanded PVC can be a style of PVC which has been expanded having a Particular foaming agent to improve the thickness of the fabric whilst lowering its density. The foaming agent has actually been A part of the design purposefully to cut back the amount of plastic is applied.
شکلدادن در فشار کم: قالبگیری بهوسیله فشار و انژکسیون بسیار سریع و برای تهیه اشیا قالبگیری شده با ابعاد کم و متوسط به کار میرود.
Furthermore, it has great electrical insulation Attributes, which makes it an acceptable content for wiring and pvc شبابيك cable applications.
