ʻO Edge ultra sonic i hoʻopaʻa ʻia welded foldable factory kumu kūʻai pale i ka mea kanu PP Corrugated Corflute Tree Guard

ʻO ka mea copolymer-type PP he haʻahaʻa haʻahaʻa haʻahaʻa wela (100 ° C), haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, haʻahaʻa rigidity, akā ʻoi aku ka ikaika o ka hopena.Hoʻonui ka ikaika o PP me ka hoʻonui ʻana i ka ʻike ethylene.ʻO ka mahana hoʻonāwaliwali o Vicat o PP he 150°C.Ma muli o ke kūlana kiʻekiʻe o ka crystallinity, ʻoi aku ka maikaʻi o kēia mea i ka ʻili a me nā waiwai kūʻē.ʻAʻole loaʻa i ka PP nā pilikia hoʻoluhi pilikia.ʻO ka maʻamau, hoʻololi ʻia ʻo PP ma ka hoʻohui ʻana i nā fibers aniani, nā mea hoʻohui metala a i ʻole nā ​​​​mea wela thermoplastic.ʻO ka kahe kahe MFR o PP mai ka 1 a hiki i ka 40. ʻO nā mea PP me ka MFR haʻahaʻa i ʻoi aku ka maikaʻi o ka hopena hopena akā haʻahaʻa haʻahaʻa.No ka mea MFR like, ʻoi aku ka ikaika o ka ʻano copolymer ma mua o ka ʻano homopolymer.Ma muli o ka crystallization, he kiʻekiʻe ka shrinkage rate o PP, maʻamau 1.8 ~ 2.5%.A ʻoi aku ka maikaʻi o ka hoʻohālikelike ʻana o ka shrinkage ma mua o ka PE-HD a me nā mea ʻē aʻe.ʻO ka hoʻohui ʻana i ka 30% aniani additive hiki ke hōʻemi i ka shrinkage i 0.7%.
