I-polyethylene wax i-polyethylene enesisindo esiphansi samangqamuzana (<1000), futhi iyinsiza evamile embonini yokucubungula ipulasitiki.Ukusetshenziswa kwe-polyethylene wax ekubumbeni kwe-plastic extrusion kungathuthukisa uketshezi lwezinto ezibonakalayo, kukhuphule ukukhiqizwa, futhi kuvumele ukugxila okuphezulu kokugcwalisa.

Pe waxisetshenziswa kabanzi ekucubunguleni umbala we-masterbatch.Inhloso yokwengeza i-polyethylene wax akukhona nje ukushintsha ukusebenza kokucubungula kombala we-masterbatch system, kodwa futhi ukukhuthaza ukusakazeka kwezingulube ku-masterbatch yombala.Ukuhlakazwa kwe-pigment kubaluleke kakhulu kumbala we-masterbatch, futhi ikhwalithi ye-masterbatch yombala incike ikakhulukazi ekuhlakazweni kwe-pigment.Ukuhlakazeka okuhle kombala, amandla aphezulu ombala we-masterbatch yombala, ikhwalithi enhle yombala wemikhiqizo, kanye nezindleko eziphansi.I-polyethylene wax ingathuthukisa izinga lokuhlakazeka kwe-pigment ngezinga elithile, futhi iyi-dispersant evamile ekukhiqizeni i-masterbatch yombala.Ngenxa yezindlela ezahlukene zokukhiqiza, i-polyethylene wax ingahlukaniswa ngezinhlobo ezimbili: uhlobo lwe-polymerization kanye nohlobo lwe-pyrolysis.Owokuqala ungumkhiqizo we-polymerization ye-high-pressure polyethylene, futhi lokhu okulandelayo kwenziwa ngokuqhekeka kwe-polyethylene okushisayo.Ngoba i-polyethylene wax enesakhiwo esihlukile samangqamuzana ingahlukaniswa ibe yi-high and low density, efana ne-polyethylene.Ngenxa yomehluko wendlela yokukhiqiza, ukuminyana, isisindo samangqamuzana, ukusatshalaliswa kwesisindo samangqamuzana kanye nesakhiwo samangqamuzana e-polyethylene wax, ukusebenza kwawo kokusetshenziswa ku-masterbatch yombala nakho kuhlukile.

Ukulungiswa kwe-polyethylene wax nge-pyrolysis
I-Pyrolysis iyindlela eyinhloko yokukhiqiza i-polyethylene wax e-China.Isisindo samangqamuzana aphezulu i-polyethylene emsulwa noma ipulasitiki ye-polyethylene eyimfucuza ifakwa nge-pyrolysed ibe i-polyethylene wax ekushiseni okuphezulu.Ikhwalithi yomkhiqizo wayo kanye nezakhiwo (njengokuqina, indawo encibilikayo, umbala obonakalayo, njll.) kuthinteka kakhulu umthombo wokuqhekeka kwezinto zokusetshenziswa.Inqubo ye-pyrolysis ilula, umthombo wezinto zokusetshenziswa ucebile, futhi izindleko zokusebenza ziphansi.Ingabona ukusetshenziswa kabusha kwe-polyethylene engcolile, enezinzuzo ezinhle zezomnotho.

Izinqubo ezikhona zokuqhekeka zifaka ukuqhekeka okushisayo, ukuqhekeka okusiza i-solvent kanye nokuqhekeka kwe-catalytic.Phakathi kwazo, ukuqhekeka okushisayo kulula kakhulu.Imikhiqizo ye-wax ye-polyethylene ingalungiswa ngokulawula izinga lokushisa lokuphendula nesikhathi, kodwa idinga ukusetshenziswa kwamandla okukhulu.

U-Xue Ping nabanye abavela e-Beijing University of Chemical Technology benza ucwaningo ngokulungiswa kwe-polyethylene wax nge-pyrolysis ye-PE resin ekushiseni okuphezulu ku-extruder yesikulufa esisodwa.I-heater yanezelwa epayipini elixhumayo phakathi kwe-extruder nethangi lokupholisa ukuze kushiswe izinto ezikulo, futhi izinga lokushisa elilungile lokuqhekeka lalingu-420 ℃, liqaphela ukukhiqizwa okuqhubekayo kwe-polyethylene wax nge-pyrolysis ye-PE resin.

U-Zhang Jianyu nabanye bafunde besebenzisa i-Al-MCM-48 njenge-catalyst yokwenza ukubola kwe-polyethylene ewudoti ukuze kulungiswe i-polyethylene wax ku-autoclave, ngezinga lokushisa lokusabela elingu-360~380 ℃ kanye nesikhathi sokusabela esingamahora angu-4.Ukusetshenziswa kwe-catalyst kunciphisa amandla okwenza kusebenze, izinga lokushisa elidingekayo lokuqhekeka nokusetshenziswa kwamandla.U-Wang Lulu nabanye bathuthukisa isivuno se-wax ye-polyethylene nge-pyrolysis ye-solvent-assisted of polyethylene waste plastics, futhi baphenya imiphumela ye-solvents ehlukene kanye nezimo zokusabela ekuvunweni nasekusebenzeni kwemikhiqizo ye-wax.Ukuhlolwa kukhombisa ukuthi isivuno se-polyethylene wax singathuthukiswa ngokusebenzisa izinyibilikisi ezinuka kamnandi, futhi isivuno singafinyelela ku-87.88% uma usebenzisa i-xylene exubile njenge-solvent.Izinyibilikisi ezinuka kamnandi zingaphinde zithuthukise ikhwalithi yomkhiqizo ngokwezinga elithile, futhi ingatholakala i-wax ye-polyethylene ephuzi ephuzi.
