ʻO ka ʻokoʻa ma waena o PP a me PVC ʻaʻohe mea mai ka helehelena a i ʻole ka manaʻo hiki ke ʻokoʻa loa;He paʻakikī ka manaʻo o PP a he palupalu ka PVC.
ʻO PP kahi resin thermoplastic i hoʻomākaukau ʻia e ka polymerization o propylene.ʻEkolu hoʻonohonoho o nā huahana isochronous, unregulated a interchronous, a ʻo nā huahana isochronous nā mea nui o nā huahana ʻoihana.Hoʻokomo pū ka Polypropylene i nā copolymers o propylene a me kahi liʻiliʻi o ka ethylene.ʻO ka maʻamau translucent kala ʻole paʻa, ʻaʻala ʻaʻohe mea ʻawaʻawa.
Nā hiʻohiʻona: ʻoi aku ka maikaʻi o nā mea ʻawaʻawa, ʻono ʻole, haʻahaʻa haʻahaʻa, ikaika, ʻoʻoleʻa, paʻakikī a me ka pale wela ma mua o ka polyethylene haʻahaʻa haʻahaʻa, hiki ke hoʻohana ʻia ma 100 degere a pēlā paha.ʻAʻole pili ʻia nā waiwai uila maikaʻi a me ka insulation kiʻekiʻe e ka haʻahaʻa, akā e lilo i brittle i ka haʻahaʻa haʻahaʻa, ʻaʻole ʻaʻahu kūʻokoʻa, maʻalahi i ka makahiki.He kūpono no ka hana ʻana i nā ʻāpana mechanical maʻamau, nā ʻāpana kū i ka corrosion a me nā ʻāpana insulation.
ʻO PVC kekahi o ka hana nui loa o ka honua i nā huahana plastic, cheap, hoʻohana nui ʻia, polyvinyl chloride resin he keʻokeʻo a i ʻole ka pauka melemele māmā.Hiki ke hoʻohui ʻia nā mea hoʻohui like ʻole e like me nā USES ʻokoʻa, a he ʻokoʻa nā ʻano kino a me nā ʻano mechanical polyvinyl chloride plastics.ʻO ka hoʻohui ʻana i ka plasticizer kūpono i loko o ka resin polychloroethylene hiki ke hana ʻia i nā ʻano huahana paʻakikī, palupalu a maopopo.ʻO ka nui o ka PCC maʻemaʻe he 1.4g / cm3, a ʻo ka nui o nā plasticizer PCC a me nā mea hoʻopihapiha maʻamau he 1.15-2.00g / cm3.ʻO ka POLYchlorethylene paʻakikī ka tensile maikaʻi, flexural, compressive a me ka hopena hopena a hiki ke hoʻohana ʻia ma ke ʻano he mea hana wale nō.
