Igishashara cya polyethylene ni polyethylene ifite uburemere buke (<1000), kandi ni umufasha usanzwe mu nganda zitunganya plastike.Gukoresha ibishashara bya polyethylene muburyo bwo kubumba plastike birashobora kuzamura ubwiza bwibikoresho, kongera umusaruro, no kwemerera kuzuza cyane.

Ibishasharani Byinshi Byakoreshejwe Mugutunganya Amabara.Intego yo kongeramo ibishashara bya polyethylene ntabwo ari uguhindura gusa imikorere yimikorere ya sisitemu ya masterbatch, ahubwo ni no guteza imbere ikwirakwizwa ryibara ryibara ryibara.Ikwirakwizwa rya pigment ningirakamaro cyane muburyo bwo gushushanya amabara, kandi ubwiza bwibara ryibara ryinshi biterwa no gukwirakwiza pigment.Gukwirakwiza neza pigment, imbaraga zo kurangi zamabara ya master master, ibara ryiza ryibicuruzwa, nigiciro gito.Igishashara cya polyethylene gishobora kuzamura urwego rwo gukwirakwiza pigment ku rugero runaka, kandi ni ikwirakwizwa rusange mu gukora amabara meza.Bitewe nuburyo butandukanye bwo gukora, ibishashara bya polyethylene birashobora kugabanywamo ubwoko bubiri: ubwoko bwa polymerisation nubwoko bwa pyrolysis.Iyambere nigicuruzwa cyumuvuduko ukabije wa polyethylene polymerisation, naho iyanyuma ikorwa na polyethylene yamashanyarazi.Kuberako ibishashara bya polyethylene bifite imiterere itandukanye ya molekuline birashobora kugabanywa mubucucike buri hejuru kandi buke, busa na polyethylene.Bitewe nuburyo butandukanye muburyo bwo gukora, ubucucike, uburemere bwa molekile, gukwirakwiza uburemere bwa molekuline nuburyo bwa molekuline yimishashara ya polyethylene, imikorere yabyo mubikorwa byamabara nayo iratandukanye.

Gutegura ibishashara bya polyethylene na pyrolysis
Pyrolysis nuburyo nyamukuru bwo gukora ibishashara bya polyethylene mubushinwa.Uburemere buke bwa molekuline yuzuye polyethylene cyangwa imyanda ya polyethylene yimyanda ihindurwamo pyrolyse mu gishashara cya polyethylene ku bushyuhe bwinshi.Ubwiza bwibicuruzwa nibiranga (nkubukomere, gushonga, ibara rigaragara, nibindi) bigira ingaruka cyane kumasoko yo kumena ibikoresho fatizo.Inzira ya pyrolysis iroroshye, isoko yibikoresho fatizo irakungahaye, kandi ikiguzi cyo gukora ni gito.Irashobora gutahura ikoreshwa ryimyanda polyethylene, hamwe nubukungu bwiza.

Inzira zisanzweho zirimo gushiramo ubushyuhe, gutabarwa-gufashwa no guturika.Muri byo, gucana amashyuza nibyo byoroshye.Ibishashara bya polyethylene birashobora gutegurwa mugucunga ubushyuhe bwigihe nigihe, ariko bisaba gukoresha ingufu nyinshi.

Xue Ping n'abandi bo muri kaminuza ya Beijing y’ikoranabuhanga ry’ubushakashatsi bakoze ubushakashatsi ku itegurwa ry’ibishashara bya polyethylene na pyrolysis ya PE resin ku bushyuhe bwinshi muri extruder imwe.Ubushyuhe bwongewe kumuyoboro uhuza hagati ya extruder na tanki yo gukonjesha kugirango ushushe ibikoresho birimo, kandi ubushyuhe bwiza bwo guturika bwari 420 ℃, bumenya umusaruro ukomeje kubyara ibishashara bya polyethylene na pyrolysis ya PE resin.

Zhang Jianyu n'abandi bize bakoresheje Al-MCM-48 nk'umusemburo kugira ngo batume habaho kwangirika kw'imyanda polyethylene kugira ngo bategure ibishashara bya polyethylene muri autoclave, hamwe n'ubushyuhe bwa 360 ~ 380 ℃ n'igihe cyo kubyitwaramo saa yine.Gukoresha catalizator bigabanya ingufu zo gukora reaction, ubushyuhe bukenewe mugucika no gukoresha ingufu.Wang Lulu n'abandi bateje imbere umusaruro w’ibishashara bya polyethylene bakoresheje pyrolysis ifashwa na solide ya plastike y’imyanda ya polyethylene, banasesengura ingaruka ziterwa n’umuti utandukanye n’imiterere y’ibisubizo ku musaruro n’imikorere y’ibicuruzwa bishashara.Ikizamini cyerekana ko umusaruro wibishashara bya polyethylene ushobora kunozwa ukoresheje imiti ya aromatiya, kandi umusaruro ushobora kugera kuri 87,88% mugihe ukoresheje xylene ivanze nkumuti.Umuyoboro wa Aromatic urashobora kandi kuzamura ubwiza bwibicuruzwa kurwego runaka, kandi ibishashara byumuhondo byoroshye bya polyethylene birashobora kuboneka.
Qingdao Sainuo Chemical Co., Ltd.Turi gukora ibishashara bya PE, ibishashara bya PP, ibishashara bya OPE, ibishashara bya EVA, PEMA, EBS, Zinc / Kalisiyumu Stearate….Ibicuruzwa byacu byatsinze REACH, ROHS, PAHS, FDA ikizamini.
Sainuo humura ibishashara, ikaze iperereza ryawe!
