Wax polyethylenehe ʻano polyolefin synthetic wax, ka mea maʻamau e pili ana i ka homopolyethylene me ke kaumaha molekala pili ma lalo o 10000. Ma ke ʻano ākea, ethylene polymers me ka ikaika maikaʻi ʻole a me ka paʻakikī a ʻaʻole hiki ke hana ʻia e like me ka mea hoʻokahi hiki ke kapa ʻia he polyethylene wax.Pe waxLoaʻa i kahi wahi palupalu kiʻekiʻe, haʻahaʻa hoʻoheheʻe viscosity, kūpaʻa kemika maikaʻi, lubricity maikaʻi a me ka wai.Ma ke ʻano he kōkua hana, hoʻohana nui ʻia ia i nā paipu PVC, nā kiʻiʻoniʻoni, nā kaula a me nā huahana palaki a me nā huahana ʻē aʻe e hoʻomaikaʻi ai i ka hana ʻana o nā huahana a hoʻomaikaʻi i ke ʻano o nā huahana i hoʻopau ʻia.

ʻO ke ʻano o ka hoʻomākaukau ʻana o ka polyethylene wax
Aia ʻekolu mau ʻano hana synthetic o ka pe wax.ʻO ka mua, ʻo ia ke ʻano hoʻoheheʻe polyethylene, kahi e wāwahi ai i ka resin polyethylene i loko o ka wax polyethylene me ke kaumaha molekala haʻahaʻa i ka wela kiʻekiʻe.ʻO ka lua, ʻo ia ke ʻano hoʻomaʻemaʻe huahana, kahi e hōʻiliʻili ai i nā huahana o nā ʻāpana haʻahaʻa haʻahaʻa haʻahaʻa i hana ʻia i ke kaʻina hana o ka ethylene polymerization a hoʻomaʻemaʻe iā lākou no ka loaʻa ʻana o ka polyethylene wax.ʻO ke kolu o ke ʻano he ethylene synthesis method, ka mea e synthesize pololei i ka polyethylene wax me ka ethylene ma ke ʻano he mea maka.I kēia lā, e alakaʻi ʻo Sainuo iā ʻoe e aʻo e pili ana i ka polyethylene wax i hoʻomākaukau ʻia e ke ʻano hana māwae a me ke ʻano synthesis.

(1) Ka hoʻomākaukau ʻana i ka wax polyethylene e ka pyrolysis
ʻO ke ʻano o ka haki ʻana ke ʻano nui o ka hana ʻana i ka polyethylene wax ma Kina.ʻO ka polyethylene maʻemaʻe maʻemaʻe a i ʻole ka polyethylene plastic kiʻekiʻe e haki ʻia 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 a me ka waihoʻoluʻu ʻike) e hoʻopilikia nui ʻia e ke kumu o ka haki ʻana i nā mea maka.He ʻenehana maʻalahi ke ʻano o ka paʻi ʻana, ke kumu waiwai o nā mea maka a me ke kumu kūʻai haʻahaʻa.Hiki iā ia ke hoʻomaopopo i ka hoʻohana hou ʻana i ka polyethylene ʻōpala me nā pono waiwai maikaʻi.Eia nō naʻe, paʻakikī ke kaʻina hana paʻa, ākea ka hāʻawi ʻana i ke kaumaha molecular o ka huahana, paʻakikī ka maikaʻi o ka polyethylene wax, a ua hana ʻia nā wahi ʻeleʻele he nui.He mea kaulana ia ma waena a me nā noi haʻahaʻa e like me ka kala masterbatch.
ʻO nā kaʻina hana maʻamau e loaʻa ana i ka māhā wela, ka haʻi ʻana i kōkua ʻia me ka solvent a me ka haʻi catalytic.I waena o lākou, ʻo ka maʻalahi ka maʻalahi loa.Hiki ke hoʻomākaukau ʻia nā huahana polyethylene wax ma o ka hoʻomalu ʻana i ka mahana a me ka manawa, akā pono ka nui o ka ikehu.Ua aʻo ka poʻe mai ke Kulanui o Beijing o ka ʻenehana kemika i ka hoʻomākaukau ʻana i ka wax polyethylene ma o ka haki ʻana i ka resin PE ma ka wela kiʻekiʻe i ka extruder screw hoʻokahi.Hoʻohui ʻia kahi mea hoʻomehana ma ka paipu hoʻohui ma waena o ka extruder a me ka pahu hoʻoluʻu e wela a nahā i ka mea.ʻO 420 ℃ ka mahana hoʻomaha maikaʻi loa, e ʻike ana i ka hana mau ʻana o ka resin PE e hoʻomākaukau ai i ka polyethylene wax.Ua aʻo kekahi poʻe i ka hoʻomākaukau ʻana i ka wax polyethylene ma o ka haki ʻana i ka polyethylene ʻōpala i loko o kahi autoclave me ka al-mcm-48 ma ke ʻano he catalyst.ʻO 360 ~ 380 ℃ ka mahana o ka hopena a ʻo 4H ka manawa pane.ʻO ka hoʻohana ʻana i ka catalyst e hoʻemi i ka ikehu hoʻāla hoʻōla, ka mahana e pono ai no ka pyrolysis 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 polyethylene waste plastics.Ua noiʻi ʻia nā hopena o nā mea hoʻoheheʻe like ʻole a me nā ʻano hopena i ka hua a me nā waiwai o ka wax.Hōʻike ka hōʻike e hiki ke hoʻomaikaʻi ʻia ka hua o ka polyethylene wax ma o ka hoʻohana ʻana i nā solvents aromatic.Ke hoʻohana nei i ka xylene i hui ʻia e like me ka solvent, ʻoi aku ka kiʻekiʻe e like me 87.88%.Hiki i nā mea hoʻoheheʻe Aromatic ke hoʻomaikaʻi i ka maikaʻi o ka huahana i kekahi ʻano a loaʻa ka māmā melemele polyethylene wax.

(2) Hoʻohui ʻia o ka polyethylene wax
ʻO ka polyethylene wax i hoʻopili pololei ʻia mai ka ethylene he maʻemaʻe kiʻekiʻe, liʻiliʻi pili i ke kaumaha molekalale, haiki hoʻoheheʻe ʻia, hiki ke hoʻololi i ka hana huahana a me ka maikaʻi paʻa.Hoʻohana ʻia ia e hana i ka polyethylene wax kiʻekiʻe a me nā ʻano like ʻole.Wahi a ka mīkini polymerization a me nā ʻano catalysts i hoʻohana ʻia, hiki ke hoʻokaʻawale ʻia ka ethylene synthesis i ka polymerization radical manuahi, Ziegler Natta (ZN) catalytic polymerization, metallocene catalytic polymerization a pēlā aku.
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!
