1. Nā mea like ʻole
Nā pahu pahu PPhe mau polypropylene resins.No ka mea he palupalu loa ka homopolymer PP i ka wā i ʻoi aku ai ka mahana ma mua o 0C, nui nā mea pāʻoihana PP he copolymers maʻamau me ka 1 ~ 4% ethylene i hoʻohui ʻia a i ʻole nā pili me nā mea ethylene kiʻekiʻe.formula copolymer.
ʻO kahi PC i loko o kahi pahu PC he aka "polycarbonate".ʻO ka polycarbonate kahi resin thermoplastic paʻakikī i loaʻa kona inoa mai nā hui CO3 i loko.E ka bisphenol A a me ke kalapona oxychloride synthesis.ʻO ke ala maʻamau i hoʻohana ʻia ʻo ia ke ʻano hoʻoheheʻe transesterification (bisphenol A a me diphenyl carbonate i synthesized e ka transesterification a me ka polycondensation).
2. Nāʻano likeʻole
Pahu PP: ʻO ka mea copolymer-type PP he haʻahaʻa haʻahaʻa haʻahaʻa wela (100C), 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 hoʻoluʻu Vicat o PP he 150C.Ma muli o ke kūlana kiʻekiʻe o ka crystallinity, ʻoi aku ka maikaʻi o ka ʻili o kēia mea a me nā waiwai kūʻē.
pahu PC: He resin thermoplastic amorphous me nā waiwai piha maikaʻi loa, me ka insulation uila maikaʻi loa, elongation, dimensional stability a me ke kūpaʻa kemika, ka ikaika kiʻekiʻe, ka pale wela a me ke kū anuanu;loaʻa iā ia iho ka hoʻopau ʻana iā ia iho, pale ahi, non-toxic, colorable, etc.
3. Ka ikaika like ʻole
ʻeke PP: ʻoi aku ka ikaika o ka hopena.ʻOi aku ka maikaʻi o ka ʻoʻoleʻa o ka ʻili a me ke kūʻē ʻana i ka ʻōpala.
Pāke PC: Hiki i kona ikaika ke hoʻokō i nā pono like ʻole mai nā kelepona paʻa i ke aniani pale.Ke hoʻohālikelike ʻia me ka metala, ʻaʻole lawa kona paʻakikī, ʻo ia ka mea e maʻalahi ai ke ʻoki ʻana i kona ʻano, akā maikaʻi loa kona ikaika a me ka paʻakikī, inā he kaumaha a maʻamau paha, ʻoiai ʻaʻole ʻoe e hoʻāʻo e wili, ua lawa ka lōʻihi.
