Lefapheng la tlhahiso ea masterbatch ea mebala, ho eketsoa ha boka ba parafine leboka ba PEe ka ntlafatsa phallo ea litsamaiso tsa lisebelisoa tsa polymer.Ka ho ntlafatsa ho koloba le ho hasana ha li-pigments le li-additives tse ling, ts'ebetso ea ts'ebetso e ka ntlafatsoa ho ea ho maemo a sa tšoaneng, e leng molemo bakeng sa ho ntlafatsa katleho ea tlhahiso le khanya e bonahalang ea lihlahisoa tse extruded.Ka hona, lifeme tse ngata li sebelisa boka ba parafine e nang le ntlha ea ho qhibiliha e ka bang 60 ℃ e le dispersant kapa hammoho le boka ba polyethylene ho eketsa tlhahiso le ho fokotsa litšenyehelo.Joale re bona liphapang tsa ts'ebetso lipakeng tsa tse peli ho latela pono ea ts'ebeliso e sebetsang ts'ebetsong ea masterbatch ea mebala.

(1) Ts'ebetso ea mocheso
Sehlahisoa sa lubricating se sebelisetsoang li-masterbatches tsa mebala se tlameha ho mamella mocheso oa ts'ebetso hantle le ho boloka botsitso ba mocheso nakong ea ho etsoa ha li-masterbatches tsa mebala le ho boptjoa ha lihlahisoa tse mebala;Ho seng joalo, dispersant e sebelisetsoang gasification kapa decomposition e tla ba le phello e mpe ts'ebetsong ea masterbatch ea mebala kapa sehlahisoa.Mocheso oa ho sebetsa oa li-masterbatches tsa mebala le lihlahisoa hangata o pakeng tsa 160-220 ℃.Re entse liteko tsa isothermal thermogravimetric kaboka ba polyethylenele boka ba parafine e nang le ntlha e qhibilihang ea 60 ℃.Liphetho li bontšitse hore ka tlase ho 200 ℃, boka ba parafine bo sutumelitse 9.57% ea boima ba eona nakong ea metsotso e 4, mme tahlehelo ea boima ba 'mele e fihlile ho 20% nakong ea metsotso e 10.Ho latela pono ea ho hanyetsa mocheso feela, boka ba polyethylene bo ka bonts'a ho hanyetsa mocheso o motle, athe boka ba parafine ho thata ho tiisa.Ka hona, boka ba boka ba parafine ha bo loketse ho sebelisoa e le "mala oa masterbatch dispersant".

(2) Ts'ebetso ea ho hasana
Ho bapisa le ho fumana hore na thepa ea ho hasana ea boka ba boka le boka ba parafine, li-masterbatches tse ntšo li ile tsa lokisoa ka likarolo tse fapaneng tsa tse peli, 'me liteko tse tšesaane tsa filimi e ntšo li ile tsa etsoa.Ka karo-karolelano ea 0-7%, masterbatch e ntšo e ile ea eketseha butle-butle ka 36.7% ka keketseho ea boka ba boka ba polyethylene, e leng se bontšang hore ho phahama ha boka ba boka ba polyethylene, ho ntlafatsa ts'ebetso ea ho hasana ha carbon black;Leha ho le joalo, ka tekanyo e tšoanang ea tlatsetso, blackbatch ea blackbatch e fokotsehile ka 19.9% ​​ka keketseho ea parafine, e leng se bontšang hore ha parafine e phahame, ts'ebetso ea ho hasana ea carbon black e mpefala.
Sena ke hobane ha se bapisoa le boka ba boka, boka ba parafine bo atisa ho kolobisa carbon black, empa ka nako e ts'oanang, bo fokotsa viscosity ea tsamaiso haholo.The viscosity e tlaase e fokolisa haholo phetiso ea matla a ho kuta 'me e sitisa ho hasana.Carbon black e koahetsoe ke bokaholimo ba parafine, 'me e etsa likaroloana tse kholoanyane tsa carbon black aggregates.Ho hlakile hore phello ena e sitisang ho hasana e feta haholo phello ea eona e fokolisang momahano ea lihlopha.

Ka hona, papiso ea liphetho tsa liteko e bontša hore boka ba polyethylene bo na le phello e ntle ea ho tlotsa le ho qhalakanya ho carbon black, ha 'mala oa masterbatch, carbon black e kentsoeng ka boka ba parafine e tla senyeha haholo.
