Wax polyethylene ʻO ka polyethylene me ke kaumaha molekala haʻahaʻa (<1000), a he mea kōkua maʻamau i ka ʻoihana hana ʻili.ʻO ka hoʻohana ʻana i ka polyethylene wax i loko o ka plastic extrusion molding hiki ke hoʻomaikaʻi i ka wai o nā mea, hoʻonui i ka hana, a ʻae i ka hoʻopiha piha ʻana.

Pe waxhoʻohana nui ʻia i ka hana masterbatch kala.ʻO ke kumu o ka hoʻohui ʻana i ka polyethylene wax ʻaʻole wale ia e hoʻololi i ka hana hana o ka ʻōnaehana masterbatch kala, akā e hoʻolaha pū i ka hoʻopuehu ʻana o nā puaʻa i ka masterbatch kala.He mea koʻikoʻi ka hoʻopuehu ʻana o ka puaʻa no ka masterbatch kala, a ʻo ka maikaʻi o ka masterbatch kala e hilinaʻi nui ʻia i ka hoʻopuehu ʻana o ka puaʻa.ʻO ka hoʻopuehu maikaʻi o nā puaʻa, ka mana kala kiʻekiʻe o ka masterbatch kala, ka maikaʻi o ka kala kala ʻana o nā huahana, a me ke kumu kūʻai haʻahaʻa.Hiki i ka polyethylene wax ke hoʻomaikaʻi i ka pae dispersion o ka puaʻa i kekahi ʻano, a he dispersant maʻamau i ka hana ʻana i ka masterbatch kala.Ma muli o nā ʻano hana like ʻole, hiki ke hoʻokaʻawale ʻia ka polyethylene wax i ʻelua ʻano: polymerization type a me pyrolysis type.ʻO ka mea mua he huahana o ka polyethylene polymerization kiʻekiʻe, a ua hana ʻia ka hope e ka polyethylene thermal cracking.No ka mea hiki ke hoʻokaʻawale ʻia ka polyethylene wax me nā ʻano molekala like ʻole i ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, e like me ka polyethylene.Ma muli o ka ʻokoʻa o ke ʻano hana hana, ka nui, ka paona molekala, ka hāʻawi ʻana i ke kaumaha molecular a me ke ʻano mole o ka polyethylene wax, ʻokoʻa hoʻi kāna hana noi i ka masterbatch kala.

Ka hoomakaukau ana i ka polyethylene wax ma ka pyrolysis
ʻO Pyrolysis ke ala nui o ka hana ʻana i ka polyethylene wax ma Kina.Hoʻopili ʻia ka polyethylene maʻemaʻe a i ʻole ka polyethylene plastic kiʻekiʻe i loko o ka polyethylene wax i ka wela kiʻekiʻe.ʻO ka maikaʻi o kāna huahana a me kona waiwai (e like me ka paʻakikī, ka helu heheʻe, ka waihoʻoluʻu ʻike, a me nā mea ʻē aʻe) e hoʻopilikia nui ʻia e ke kumu o ka haki ʻana i nā mea maka.He mea maʻalahi ke kaʻina hana o ka pyrolysis, waiwai ke kumu o nā kumu waiwai, a haʻahaʻa ke kumukūʻai hana.Hiki iā ia ke hoʻomaopopo i ka hoʻohana hou ʻana i ka polyethylene ʻōpala, me nā pono waiwai maikaʻi.

ʻO nā kaʻina hana hoʻoheheʻe i kēia manawa, ʻo ia ka puʻupuʻu wela, ka haʻi kōkua solvent a me ka cracking catalytic.I waena o lākou, ʻo ka maʻalahi ka maʻalahi loa.Hiki ke hoʻomākaukau ʻia nā huahana polyethylene wax ma ke kāohi ʻana i ka mahana a me ka manawa, akā pono ia i ka hoʻohana nui ʻana i ka ikehu.

Ua hana ʻo Xue Ping a me nā mea ʻē aʻe mai Beijing University of Chemical Technology i ka noiʻi e pili ana i ka hoʻomākaukau ʻana o ka polyethylene wax ma o ka pyrolysis o ka resin PE ma ke kiʻekiʻe wela i kahi extruder hoʻokahi-screw.Hoʻohui ʻia kahi mea hoʻomehana ma ka paipu hoʻohui ma waena o ka extruder a me ka pahu hoʻoluʻu e wela ai ka mea i loko o ia mea, a ʻo ka mahana ʻoi loa ʻo 420 ℃, e ʻike ana i ka hana mau ʻana o ka polyethylene wax e ka pyrolysis o ka resin PE.

Ua aʻo ʻo Zhang Jianyu a me nā mea ʻē aʻe me ka hoʻohana ʻana iā Al-MCM-48 ma ke ʻano he catalyst e hoʻopololei i ka decomposition o ka ʻōpala polyethylene e hoʻomākaukau ai i ka polyethylene wax i loko o ka autoclave, me ka mahana o ka hopena o 360~380 ℃ a me ka manawa pane o 4 h.ʻO ka hoʻohana ʻana i ka catalyst e hoʻemi i ka ikehu hoʻāla ʻana, ka mahana e pono ai no ka haki ʻana a me ka hoʻohana ʻana i ka ikehu.Ua hoʻomaikaʻi ʻo Wang Lulu a me nā mea ʻē aʻe i ka hua o ka polyethylene wax ma o ka solvent-assisted pyrolysis o ka polyethylene waste plastics, a ua noiʻi i nā hopena o nā mea hoʻoheheʻe like ʻole a me nā kūlana pane i ka hua a me ka hana o nā huahana wax.Hōʻike ka hōʻike e hiki ke hoʻomaikaʻi ʻia ka hua o ka polyethylene wax ma o ka hoʻohana ʻana i nā solvents aromatic, a hiki i ka hua ke hiki i 87.88% ke hoʻohana ʻia ka xylene i hui ʻia e like me ka solvent.Hiki i nā mea hoʻoheheʻe Aromatic ke hoʻomaikaʻi i ka maikaʻi o ka huahana i kekahi ʻano, a hiki ke loaʻa ka māmā melemele polyethylene wax.
Qingdao Sainuo Chemical Co., Ltd.ʻO mākou ka mea hana no ka PE wax, PP wax, OPE wax, EVA wax, PEMA, EBS, Zinc / Calcium Stearate….Ua hala kā mākou huahana i ka REACH, ROHS, PAHS, FDA hoʻāʻo.
ʻO Sainuo, e hoʻokipa i kāu nīnau!
