Polypropylene SP179 no ka pahu kaʻa
Polypropylene SP179 no ka pahu kaʻa,
polypropylene no nā ʻāpana kaʻa, PP resin no ka bumper, Sinopec PP SP179,
ʻO ka resin polypropylene kekahi o kā mākou huahana nui, ʻo ka polypropylene resin kahi polymer crystalline.ʻO nā huahana granule cylindrical, ʻaʻohe mea haumia mechanical.ʻO ka haʻahaʻa haʻahaʻa pili o ka huahana (0.90g/cm3-0.91g/cm3) e hana i ka huahana noi i ke aniani maikaʻi a me ka ʻālohilohi o ka ʻili, a loaʻa ka insulation uila maikaʻi a me ke kūpaʻa kemika.ʻO ka hoʻohui ʻana i nā mea hoʻohui kemika hiki ke hoʻomaikaʻi maikaʻi i ka hana huahana a hiki ke hoʻopili ʻia i nā māla huahana hou aʻe.Hiki ke hoʻohana nui ʻia ka Polypropylene i ka hoʻoheheʻe ʻana, ka hoʻoheheʻe ʻana, ka extrusion, ka uhi ʻana, ke kaula a me ka uea sheath, extrusion monofilaments, narrow band, film, fiber, etc., ma nā ʻano like ʻole o ka ʻoihana, ka mahiʻai a me nā mea e pono ai i kēlā me kēia lā.
ʻO SP179 kahi mea kūikawā no ka bumper kaʻa.Hōʻike ʻia nā huahana i hana ʻia mai kēia resin e ka hana wikiwiki a me ka hana maikaʻi loa.

Palapala noi
Hoʻohana nui ʻia ka copolymer hopena PP i ka hana ʻana i nā huahana ʻoihana, e like me ka dashboard, nā mea hoʻonaninani kūloko, nā bumper kaʻa.Hiki ke hoʻohana ʻia no ka hana ʻana i nā ʻatikala hale, e like me nā pāpale omole, nā mea kuke, nā lako, nā mea pāʻani, nā mea hana, nā pahu huakaʻi, nā ʻeke a me nā pahu pahu like ʻole.
Hoʻopili a me ka lawe ʻana
ʻO PP SP 179 na Sinopec Qilu l kahi papa polypropylene (PP) i hoʻopaʻa ʻia e UV.Hōʻike i ke kahe waena a me ka rigidity a me ka haʻahaʻa haʻahaʻa hopena hopena.He kūpono no ke ʻano hana hoʻoheheʻe injection.Hoʻolālā ʻia ʻo PP SP 179 no nā ʻāpana o waho kaʻa e like me ka bumper me nā kikoʻī automotive
