Edge ultra sonic shãfe haske welded mai ninkaya farashin masana'anta ya kare shuka PP Corrugated Corflute Tree Guard

Nau'in nau'in PP na copolymer yana da ƙananan zafin jiki na murdiya (100 ° C), ƙarancin gaskiya, ƙarancin sheki, ƙarancin ƙarfi, amma yana da ƙarfin tasiri mai ƙarfi. Ƙarfin PP yana ƙaruwa tare da haɓaka abun ciki na ethylene. Zazzabi mai laushi na Vicat na PP shine 150 ° C. Saboda babban matakin crystallinity, wannan abu yana da kyau taurin saman da karce kaddarorin juriya. PP ba shi da matsalolin damuwa na muhalli. Yawanci, PP ana canza ta ta hanyar ƙara filayen gilashi, ƙari na ƙarfe ko robar thermoplastic. Matsakaicin adadin MFR na PP ya fito daga 1 zuwa 40. Kayan PP tare da ƙananan MFR suna da tasiri mafi tasiri amma ƙananan ductility. Don kayan MFR guda ɗaya, ƙarfin nau'in copolymer ya fi na nau'in homopolymer. Saboda crystallization, da shrinkage kudi na PP ne quite high, kullum 1.8 ~ 2.5%. Kuma daidaituwar shugabanci na shrinkage ya fi na PE-HD da sauran kayan. Ƙara 30% ƙari gilashin zai iya rage raguwa zuwa 0.7%.
