ʻO ke kaula ʻano hana maka mea-Polypropylene
ʻO ke kaula synthetic maka kumu-Polypropylene,
Polypropylene no ke kaula palaki, ʻO ka mea hana kaula kaula,
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.
Hoʻohana maʻamau no ka papa PP

ʻO ka polypropylene paha ka mea maʻamau i loaʻa i nā kaula i hoʻohana ʻia ma ke kula kai.ʻO kekahi kumu, ʻoi aku ka māmā ma mua o ka wai, a pēlā e lana ai.
Ua kapa ʻia ʻo Polypropylene Plastic Rope ʻo "Polypropene Rope" a i ʻole "PP Plastic Rope".Hana ʻia ʻo ia me kēia: Monomer Propylene a me ka polymerization ulu ʻo ia ka polymer thermoplastic, paʻa a paʻakikī i hoʻohana ʻia i nā noi like ʻole.ʻO ke kumu kemika no Polypropylene (C3H6)n.
