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 ka 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%.
