Polypropylene Copolymer Sinopec Qilu,
PP resin no na kaula, ʻO ka resin PP no nā kāʻei ʻeke ton, ʻO ka resin PP no nā ʻeke i ulana ʻia,

ʻO ka polypropylene he resin synthetic i hana ʻia e ka polymerization o propylene (CH3—CH=CH2) me H2 ma ke ʻano he mea hoʻololi paona molekala.Aia ʻekolu stereomers o PP - isotactic, atactic a me syndiotactic.ʻAʻohe pūʻulu polar ʻo PP a loaʻa iā ia nā waiwai insulation uila maikaʻi loa.ʻO ka liʻiliʻi o ka lawe ʻana i ka wai ma lalo o 0.01%.ʻO PP kahi polymer semi-crystalline me ke kūpaʻa kemika maikaʻi.Paʻa ia i ka hapa nui o nā mea kemika koe wale nō nā oxidizer ikaika.ʻAʻohe hopena pōʻino o ka waika inorganic, alkali a me ka paʻakai ma PP.He maikaʻi ka pale wela a me ka haʻahaʻa haʻahaʻa.Aia kona wahi hehee ma kahi o 165 ℃.Loaʻa iā ia ka ikaika tensile kiʻekiʻe a me ka paʻakikī o ka ʻili a me ka maikaʻi o ke kaiapuni koʻikoʻi.Hiki iā ia ke kū mau i ka 120 ℃.

ʻO Sinopec ka mea hana PP nui loa ma Kina, ʻO kona mana PP he 45% o ka nui o ka ʻāina.Loaʻa i ka hui i kēia manawa he 29 mau mea kanu PP ma ke kaʻina hana mau (me nā mea i kūkulu ʻia).ʻO nā ʻenehana i hoʻohana ʻia e kēia mau ʻāpana ʻo ia ke kaʻina hana HYPOL a Mitsui Chemical, ke kaʻina hana kinoea a Amoco, ke kaʻina hana Spheripol a me Spherizone a Basell a me ke kaʻina hana kinoea a Novolen.Me kona mana noiʻi ʻepekema ikaika, ua hoʻomohala kūʻokoʻa ʻo Sinopec i kahi kaʻina hana lua-hanau no ka hana PP.

Nā hiʻohiʻona PP

1. He liʻiliʻi ka liʻiliʻi pili, ʻo 0.89-0.91 wale nō, ʻo ia kekahi o nā ʻano māmā loa i nā plastics.

2.good mechanical properties, ma waho aʻe o ka hopena o ke kū'ēʻana,ʻoi aku ka maikaʻi o nā mea mechanical'ē aʻe ma mua o ka polyethylene, maikaʻi ka hana hana hoʻoheheʻeʻana.

3. Loaʻa iā ia ke kūpaʻa wela kiʻekiʻe a hiki i ka mahana hoʻohana mau ke hiki i 110-120 °C.

4. maikaʻi kemika waiwai, aneaneʻaʻohe wai absorption, aʻaʻole i react me ka nui kemika.

5.ʻo ka kikokikona he maʻemaʻe,ʻaʻohe meaʻawaʻawa.

He maikaʻi ka 6.electrical insulation.

ʻO ka PP i hāʻawi ʻia e kā mākou hui ʻo ia ka uea kaha kiʻi, copolymer grade, a me ka uea-drawing grade i hoʻohana nui ʻia i ka ʻoihana i ulana ʻia, nā ʻeke i ulana ʻia, nā kāʻei ʻeke ton, nā kaula, a me nā mea ʻē aʻe, a hiki ke hoʻohana ʻia i ka hoʻoheheʻe PP. ʻoihana, ʻāpana, kīʻaha, etc.
Hoʻohana nui ʻia ka Polypropylene Copolymer i ka hana ʻana i nā huahana ʻoihana, e like me nā dashboards, nā kaʻa kaʻa, nā pahu kaʻa, nā ʻaoʻao o loko a me waho o nā mīkini holoi, nā pahu pahu a me nā pahu wai.Hiki ke hoʻohana ʻia e hana i nā mea hale e like me nā lako, nā mea pāʻani, nā ʻeke a me nā pahu pahu like ʻole.
