I kēia manawa, ʻekolu ʻano nui o nā ʻano hana hana noPE wax: ʻO ka mua, hoʻohui ʻia ka polyethylene wax e ka hopena oligomerization o ka ethylene monomer, e like me ke ʻano oligomerization radical manuahi;ʻO ka lua he polyethylene wax i hoʻomākaukau ʻia e ka degradation o polymers;ʻO ke kolu ka huahana i ka hana synthesis o ka polyethylene, e like me ka polyethylene wax i loaʻa ma ka hoʻokaʻawale ʻana i ka huahana i ka polyethylene synthesis kiʻekiʻe.

1. Ethylene polymerization ala
ʻEkolu mau ala nui no ka hana ʻana i ka polyethylene wax ma o ka ethylene polymerization.ʻO kekahi ka polymerize me ka hoʻohana ʻana i nā catalysts radical manuahi i ka wela kiʻekiʻe a me ke kaomi;ʻO ka lua ka polymerize ma lalo o ke kaomi haʻahaʻa me ka hoʻohana ʻana i nā catalysts Ziegler;ʻO ke kolu ka polymerization o ka metallocene catalysts.
2. ʻO ke ʻano hana hoʻoheheʻe polyethylene
Ka puunaue kaumaha molekala opolyethylene waxhana ʻia e ke ʻano polymerization he haiki, a hiki ke hoʻokele lima ʻia ka nui o ke kaumaha molekala pili, akā pono e hana ʻia ma kahi mea nui me ka hoʻopukapuka kiʻekiʻe.Hoʻohana maʻamau ka poʻe hana hale i ke ʻano hoʻoheheʻe wela o ka polyethylene kaumaha kiʻekiʻe no ka hana ʻana.Hiki i kēia ʻano hana ke hoʻohana i ka polyethylene resin a i ʻole polyethylene waste plastic e like me ka mea maka.Hoʻopuka ka mea mua i nā huahana kiʻekiʻe, aʻo ka mea hope e hana i nā huahana haʻahaʻa.Hiki ke ʻoki ʻia ka polyethylene kaumaha kiʻekiʻe i loko o ka wax polyethylene paona haʻahaʻa ma lalo o nā kūlana kaʻawale ea.ʻO nā waiwai e pili ana i ke ʻano o ka polyethylene wax i hoʻomākaukau ʻia, e like me ka crystallinity, density, hardness, a me ka helu heheʻe, ua hoʻopili ʻia e nā mea maka.Hoʻokaʻawale ʻia nā ʻano hana hoʻoheheʻe ʻana i ke ʻano kīʻaha kettle a me ke ʻano extrusion.

ʻO ke kaʻina hana kīhāpai he ʻano hana hana manawaleʻa, kūpono i nā mea hana me ka haʻahaʻa haʻahaʻa a me ka liʻiliʻi o ka hana hana;ʻO ke ʻano extrusion kahi kaʻina hana hoʻomau kūpono no nā ʻoihana me ka nui o ka hana nui a me ka mana hana kiʻekiʻe.

Hiki ke hoʻomākaukau ʻia ka polyethylene wax ma o ka hoʻohana ʻana i ka solution cracking polyethylene recycled.Loaʻa i kēia ʻenehana kahi kumu waiwai a me ke kumu kūʻai ʻole o nā mea maka, kahi kaʻina hana maʻalahi, a me nā koina hana haʻahaʻa.
3. Hoʻomaʻemaʻe i nā huahana polyethylene
I ka hopena o ka hana ʻana i ka polyethylene mai ka ethylene polymerization, hiki ke hoʻihoʻi ʻia nā huahana polyethylene wax mai kahi hui ʻana o nā ʻāpana haʻahaʻa haʻahaʻa a me nā mea hoʻoheheʻe i loaʻa ma ke ʻano he huahana.Ma hope o ka wehe ʻana i ka mea hoʻoheheʻe a me ka mea hoʻomaka mai ka huahana o ka mea kanu polyethylene, ʻo ka hāʻawi ʻana i ke kaumaha molekala o ka huahana he ākea loa, e kaupalena ana i kāna kahua noi a koi hou i ka hoʻomaʻemaʻe ma o ka wehe ʻana i ka solvent.ʻO kēia huahana o ka polyethylene wax ka mea maʻamau i loaʻa nā molekala me kahi paona molekala pili ma kahi o 1000, no laila ʻoi aku ka haʻahaʻa o kona mau waiwai kino e like me ka ikaika mechanical a me ke kūpaʻa wela ma mua o nā mea i hana ʻia e ka ethylene polymerization.

4. Hoʻololi i ka polyethylene wax
ʻO ka polyethylene wax kahi mole polar ʻole, a inā hiki ke hoʻokomo ʻia nā pūʻulu polar i loko o ka mole, e hoʻonui nui ia i kāna mau noi.Hiki ke hana ʻia kēia mau polyethylene waxes e ka copolymerization o ka ethylene me nā monomers i loko o ka oxygen, a i ʻole ma ka hoʻokomo ʻana i nā hui carboxyl ma o nā ʻano kemika e like me ka oxidation a me ka grafting, a laila hoʻololi hou ʻia ma o nā hopena kemika e like me ka esterification, amidation, a me ka saponification.Hiki i kēia mau polyethylene waxes ke hoʻokō i nā koi o nā noi like ʻole.
No nā kikoʻī hou aku, e ʻoluʻolu e nīnau mai iā mākou!             ninau
Hui Qingdao Sainuo.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!
