PP resin no ka PP orientation stretching polypropylen
ʻO ka resin PP no ka hoʻonohonoho ʻana i ka polypropylen PP,
ʻO ka resin polypropylene e hana i ke kiʻiʻoniʻoni OPP,
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

Pūʻolo
Me ka ʻoi aku o 100 mau ʻano like ʻole ʻo Polypropylene Film kekahi o nā kiʻiʻoniʻoni i hoʻohana nui ʻia ma ka honua.ʻO kahi noi maʻamau no ka polypropylene e like me ka polypropylene oriented (OPP).Loaʻa i kēia kiʻiʻoniʻoni maikaʻi loa nā waiwai hōʻoia no ka hoʻomaʻamaʻa ʻana i kēia mea maikaʻi no ka hoʻohana ʻana i nā inika maʻamau e hoʻopuka i kahi hopena paʻi akaka loa.ʻO ia i kēia lā kahi kiʻiʻoniʻoni hoʻopihapiha maʻalahi ka lua i ka polyethylene haʻahaʻa haʻahaʻa i ka nui.
(OPP) Kiʻiʻoniʻoni Polypropylene
ʻO kahi polymer thermoplastic i hoʻohana ʻia i nā ʻano noi like ʻole mai ka hoʻopili ʻana, a i nā kāpeti.ʻO ka hoʻohana mua ʻana o ka kiʻi ʻoniʻoni OPP i loko o ka hoʻopili meaʻai ma muli o ka ikaika maikaʻi, ka mālamalama kiʻekiʻe, nā waiwai pale kūpono a me ke kumu kūʻai haʻahaʻa i hoʻohālikelike ʻia me cellophane.Loaʻa ia ma nā wahi āpau o kou ola i kēlā me kēia lā.ʻO ka polypropylene ke kū'ē loa i ka luhi.No laila hiki ke wehe ʻia a pani ʻia kahi hinge ʻano plastik ma mua o 1000 mau manawa me ka luhi ʻole.Loaʻa kēia i ka hapa nui o nā pahu flip-top.Loaʻa ka hoʻoheheʻe ʻana o ka polypropylene ma o ka extrusion a me ka hoʻoheheʻe ʻana.ʻO ke ʻano hana maʻamau i hoʻohana ʻia ʻo ka hoʻoheheʻe ʻana.ʻO nā ʻano hana ʻē aʻe, ʻo ia ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana i ka hoʻoheheʻe ʻana.Ma ka loaʻa ʻana o ka hiki ke hoʻohālikelike i kekahi mau māka me nā waiwai molekala kikoʻī i ka wā o ka hana ʻana no ka nui o nā noi hoʻohana hope.ʻO kahi laʻana o kēia ka hoʻohana ʻana i kahi mea hoʻohui antistatic e kōkua i ka ʻili polypropylene e pale i ka lepo a me ka lepo.
