PP resin no ka hoʻopili ʻana,
lāʻau lapaʻau, uwea fiber optical, Hoʻohana ʻia ka resin PP no ke kaʻa,

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.

Ma 25kg ʻeke, 16MT i hoʻokahi 20fcl me ka ʻole pallet a i ʻole 26-28MT i hoʻokahi 40HQ me ka ʻole pallet a i ʻole 700kg ʻeke jumbo, 26-28MT i hoʻokahi 40HQ me ka ʻole pallet.

ʻO ka polypropylene he mea ʻawaʻawa ʻole, ʻaʻala ʻole, ʻono keʻokeʻo keʻokeʻo keʻokeʻo kiʻekiʻe crystallization polymer, ʻo ia kekahi o nā ʻano māmā loa o nā plastics āpau i kēia manawa, maikaʻi formability, nā huahana ma luna o ka luster, ka wela wela, ka corrosion resistance, nā huahana i loaʻa i ka mahu disinfection ka mea maikaʻi loa o ka polypropylene .

ʻO ka mea nui o ka polypropylene he propylene, ka mea i hana nui ʻia mai ka naphtha, methanol a me propane.

Wahi a nā helu helu, ma ka hopena o 2018, ua ʻoi aku ma mua o 160 mau ʻoihana hana propylene ma Kina, me ka mana hana makahiki ma kahi o 32.3 miliona mau tons a me ka hoʻopuka makahiki ma kahi o 27.1 miliona tons, kahi ulu makahiki ma kahi o 2.26. %.

ʻAʻole pili ke kumu kūʻai o propylene wale nō e ke kumukūʻai o ka aila ʻaila, methanol, propane, akā pū kekahi ma ka mākeke hoʻolako a me ka pilina pili.

ʻO kēia ʻano mea kemika i hoʻohana nui ʻia i ka ulana plastik, ka pahu, kaʻa,lāʻau lapaʻau, uwea fiber opticala me nā kula ʻē aʻe, i ka hoʻomohala ʻana i nā ʻoihana hou, hoʻonui, e loaʻa nā koi hou.

Me ka hoʻomau mau ʻana o kā mākou hoʻokele waiwai, ke hōʻike nei ka ʻoihana hoʻoili plastik i kahi ʻano koi hou o ka "functionalization", "māmā" a me ka "micro-molding", ka mea e hoʻolalelale i ka ulu paʻa o ka noi no ka hoʻoheheʻe ʻana i ka paia lahilahi, ka copolymerization hopena kiʻekiʻe. , fiber a me nā huahana polypropylene ʻē aʻe.
