Polyethylene boka ke polyethylene e nang le boima bo tlase ba molek'hule (<1000), 'me ke thuso e tloaelehileng indastering ea ho lokisa polasetiki.Ts'ebeliso ea boka ba polyethylene ha ho etsoa polasetiki ea extrusion e ka ntlafatsa mokelikeli oa thepa, ea eketsa tlhahiso, 'me ea lumella khatello e phahameng ea li-filler.

Pe bokae sebelisoa haholo ts'ebetsong ea masterbatch ea mebala.Morero oa ho kenyelletsa boka ba polyethylene ha se feela ho fetola ts'ebetso ea sistimi ea masterbatch ea mebala, empa hape ke ho khothaletsa ho hasana ha li-pigments ka masterbatch ea mebala.Ho hasana ha pigment ho bohlokoa haholo bakeng sa 'mala oa masterbatch,' me boleng ba 'mala oa masterbatch bo itšetlehile haholo ka ho hasana ha pigment.Phatlalatso e ntle ea li-pigment, matla a phahameng a mebala a masterbatch ea mebala, boleng bo botle ba 'mala oa lihlahisoa, le theko e tlase.Polyethylene wax e ka ntlafatsa boemo ba ho hasana ha pigment ho isa bohōleng bo itseng, 'me ke dispersant e tloaelehileng tlhahisong ea masterbatch ea mebala.Ka lebaka la mekhoa e fapaneng ea tlhahiso, boka ba polyethylene bo ka aroloa ka mefuta e 'meli: mofuta oa polymerization le mofuta oa pyrolysis.Ea pele ke sehlahisoa sa polyethylene polymerization ea khatello e phahameng, 'me ea ho qetela e thehoa ke ho phunyeha ha mocheso oa polyethylene.Hobane boka ba polyethylene le sebopeho se fapaneng sa molek'hule se ka aroloa ka bongata bo phahameng le bo tlaase, bo tšoanang le polyethylene.Ka lebaka la liphapang tsa mokhoa oa tlhahiso, boima ba 'mele, boima ba limolek'hule, kabo ea boima ba limolek'hule le sebopeho sa limolek'hule tsa boka ba polyethylene, ts'ebetso ea eona ea kopo ho masterbatch ea mebala le eona e fapane.

Ho lokisoa ha boka ba polyethylene ka pyrolysis
Pyrolysis ke mokhoa o ka sehloohong oa ho hlahisa boka ba polyethylene Chaena.Boima bo phahameng ba molek'hule polyethylene e hloekileng kapa polasetiki ea litšila ea polyethylene e kenngoa ka pyrolysed ka boka ba polyethylene mocheso o phahameng.Boleng ba sehlahisoa sa eona le thepa (e kang ho thatafala, ntlha ea ho qhibiliha, 'mala o bonahalang, joalo-joalo) li ameha haholo ke mohloli oa ho senya lihlahisoa tse tala.Ts'ebetso ea pyrolysis e batla e le bonolo, mohloli oa lihlahisoa tse tala o ruile, 'me litšenyehelo tsa ho sebetsa li tlaase.E ka hlokomela ho sebelisoa hape ha litšila tsa polyethylene, ka melemo e metle ea moruo.

Mekhoa e teng ea ho phunyeha e kenyelletsa ho phunyeha ha mocheso, ho phunyeha ka thuso ea solvent le catalytic cracking.Har'a tsona, ho phunyeha ha mocheso ke ho bonolo ka ho fetisisa.Lihlahisoa tsa boka ba polyethylene li ka lokisoa ka ho laola mocheso oa karabelo le nako, empa e hloka tšebeliso e ngata ea matla.

Xue Ping le ba bang ba Beijing University of Chemical Technology ba ile ba etsa lipatlisiso mabapi le ho lokisa boka ba polyethylene ka pyrolysis ea PE resin ka mocheso o phahameng ka extruder e le 'ngoe.Ho ile ha eketsoa heater holim'a phala e kopanyang pakeng tsa extruder le tanka e pholileng ho futhumatsa thepa e ho eona, 'me mocheso o motle oa ho phunyeha e ne e le 420 ℃, ho hlokomela tlhahiso e tsoelang pele ea boka ba polyethylene ka pyrolysis ea PE resin.

Zhang Jianyu le ba bang ba ile ba ithuta ka ho sebelisa Al-MCM-48 e le mohloli oa ho susumetsa ho bola ha litšila tsa polyethylene ho lokisa boka ba polyethylene ka autoclave, ka mocheso oa karabelo oa 360 ~ 380 ℃ le nako ea ho arabela ea 4 h.Tšebeliso ea catalyst e fokotsa karabelo ea ts'ebetso ea matla, mocheso o hlokahalang bakeng sa ho phatloha le ho sebelisoa ha matla.Wang Lulu le ba bang ba ntlafalitse tlhahiso ea boka ba polyethylene ka pyrolysis e thusoang ke solvent ea lipolasetiki tsa litšila tsa polyethylene, 'me ba batlisisa liphello tsa mefuta e fapaneng ea lihlapolli le maemo a itšoarang ka lihlahisoa le ts'ebetso ea lihlahisoa tsa boka.Tlhahlobo e bontša hore lihlahisoa tsa boka ba boka ba polyethylene li ka ntlafatsoa ka ho sebelisa li-solvents tse nkhang hamonate, 'me lihlahisoa li ka fihla ho 87.88% ha u sebelisa xylene e tsoakiloeng e le solvent.Li-solvents tse nkhang hamonate li ka boela tsa ntlafatsa boleng ba sehlahisoa ho isa bohōleng bo itseng, 'me boka ba bosehla ba polyethylene bo ka fumanoa.
