Ka ọ dị ugbu a, e nwere ụdị isi atọ nke ụzọ mmepụta makaPE wax: mbụ, polyethylene wax na-emepụta site oligomerization mmeghachi omume nke ethylene monomer, dị ka free radical oligomerization usoro;Nke abụọ bụ polyethylene wax nke a kwadebere site na mmebi nke polymers;Nke atọ bụ ihe na-emepụta n'ime usoro nhazi nke polyethylene, dị ka polyethylene wax nwetara site na-ekewapụta ihe na-emepụta ihe na-arụ ọrụ na polyethylene njikọ dị elu.
1. Ethylene polymerization usoro
Enwere ụzọ atọ bụ isi maka imepụta polyethylene wax site na ethylene polymerization.Otu bụ polymerize site na iji free radical catalysts na elu okpomọkụ na nrụgide;Nke abụọ bụ polymerize n'okpuru obere nrụgide site na iji Ziegler catalysts;Nke atọ bụ polymerization nke metallocene catalysts.
2. Usoro mgbawa nke polyethylene
The molekụla arọ nkesa nkepolyethylene waxemebere site na usoro polymerization dị warara, na nha nha nha molekul nwere ike iji aka na-achịkwa ya, mana a ga-emerịrị ya na nnukwu ngwaọrụ nwere nnukwu ego.Ndị na-emepụta ụlọ na-ejikarị usoro mgbawa ọkụ nke polyethylene dị arọ dị elu maka mmepụta.Usoro a nwere ike iji ma ọ bụ polyethylene resin ma ọ bụ polyethylene mkpofu plastic dị ka akụrụngwa.Nke mbụ na-emepụta ngwaahịa dị elu, ebe nke ikpeazụ na-emepụta ngwaahịa dị ala.Polyethylene dị arọ nke dị elu nwere ike ịgbawa n'ụzọ na-ekpo ọkụ ka ọ bụrụ polyethylene dị arọ molekul n'okpuru ọnọdụ kewapụrụ ikuku.Ngwongwo ndị metụtara nhazi nke polyethylene wax a kwadebere, dị ka kristal, njupụta, isi ike, na ebe mgbaze, na-emetụta ihe niile na-emepụta ihe.A na-ekewa ụzọ nhazi mgbawa n'ime usoro mgbawa kettle na usoro extrusion.
Usoro kettle mgbawa bụ usoro nhazi oge, nke dabara adaba maka ndị na-emepụta ihe na-emepụta obere mmepụta na obere ikike mmepụta;The extrusion usoro bụ a na-aga n'ihu mmepụta usoro adabara ụlọ ọrụ na nnukwu mmepụta mpịakọta na elu mmepụta ikike.
Enwere ike ịkwadebe wax polyethylene site na iji ngwọta mgbawa nke polyethylene emegharịrị.Teknụzụ a nwere ebe akụrụngwa bara ụba na nke dị ọnụ ala, usoro dị mfe, yana ọnụ ahịa ọrụ dị ala.
3. Ịdị ọcha nke ngwaahịa polyethylene
Na mmeghachi omume nke imepụta polyethylene site na ethylene polymerization, ngwaahịa polyethylene wax nwere ike nwetaghachi site na ngwakọta nke obere ihe dị arọ nke molekụla na ihe mgbaze enwetara dị ka ngwaahịa.Mgbe o wepụsịrị ihe mgbaze na onye na-amalite site na ngwaahịa nke polyethylene osisi, nkesa molekụla dị arọ nke ngwaahịa ahụ ka dị nnọọ obosara, nke na-egbochi mpaghara ngwa ya ma na-achọ ka ọ dị ọcha site na nkewa ihe mgbaze.Ihe a na-emepụta nke polyethylene wax na-enwekarị ụmụ irighiri ihe nwere ihe dị arọ nke ihe dị ka 1000, yabụ njirimara anụ ahụ ya dị ka ike igwe na nguzogide okpomọkụ dị ala karịa nke ethylene polymerization mepụtara.
4. Mgbanwe nke polyethylene wax
Polyethylene wax bụ molekul na-abụghị polar, ma ọ bụrụ na enwere ike itinye otu polar n'ime molekul ahụ, ọ ga-agbasawanye mpaghara ngwa ya.Enwere ike imepụta polyethylene waxes ndị a na-arụ ọrụ site na copolymerization nke ethylene nwere monomers oxygen nwere, ma ọ bụ site na iwebata otu carboxyl site na ụzọ kemịkalụ dị ka oxidation na grafting, wee gbanwee ọzọ site na mmeghachi omume kemịkalụ dị ka esterification, amidation, na saponification.Ihe ndị a na-arụ ọrụ polyethylene nwere ike imezu ihe achọrọ nke ngwa dị iche iche.
