ʻO ke kumukūʻai hale hana hiki ke hoʻopaʻa ʻia ʻo Edge ultra sonic e pale i ka mea kanu PP Corrugated Corflute Tree Guard

ʻO ka mea PP ʻano copolymer he haʻahaʻa ka mahana hoʻololi wela (100 ° C), haʻahaʻa ka transparency, haʻahaʻa ka ʻōlinolino, haʻahaʻa ka paʻakikī, akā he ikaika ka hopena. Hoʻonui ka ikaika o PP me ka hoʻonui ʻana i ka nui o ka ethylene. ʻO ka mahana palupalu Vicat o PP he 150 ° C. Ma muli o ke kiʻekiʻe o ka crystallinity, loaʻa i kēia mea ka paʻakikī o ka ʻili a me nā waiwai kū'ē i ke kahakaha. ʻAʻohe pilikia o ka haki ʻana o ke kaiapuni o PP. ʻO ka maʻamau, hoʻololi ʻia ka PP ma ka hoʻohui ʻana i nā olonā aniani, nā mea hoʻohui metala a i ʻole ka rubber thermoplastic. ʻO ka helu kahe MFR o PP mai 1 a 40. ʻOi aku ka maikaʻi o ka pale ʻana o nā mea PP me ka MFR haʻahaʻa akā haʻahaʻa ka ductility. No ka mea MFR like, ʻoi aku ka kiʻekiʻe o ka ikaika o ke ʻano copolymer ma mua o ke ʻano homopolymer. Ma muli o ka crystallization, kiʻekiʻe loa ka helu shrinkage o PP, maʻamau 1.8 ~ 2.5%. A ʻoi aku ka maikaʻi o ke ʻano like o ka shrinkage ma mua o ka PE-HD a me nā mea ʻē aʻe. ʻO ka hoʻohui ʻana i 30% o ka mea hoʻohui aniani hiki ke hōʻemi i ka shrinkage i 0.7%.
