Tšebeliso ea boka ba boka joalo ka ha pigment dispersant in colour masterbatch in China e qalile ka 1976, ha e ne e le sehlahisoa sa polyethylene polymerization e phahameng haholo. Polyethylene boka e hlahisoang ke mokhoa oa pyrolysis o qalile ka 1980 mme e se e sebelisoa kajeno.

Masterbatch ke pigment concentrate e nang le resin joalo ka sejari.Li-pigments li teng libakeng tse tharo: likaroloana tsa mantlha, li-aggregates le li-aggregates.The hasanya mochine oa thepa e tala ke tshebetso eo ho eona likaroloana agglomerate robehile ka agglomerate le likaroloana tse ka sehloohong, 'me likaroloana tse sa tsoa hlahisoa ebe e tsitsisoa.

Mokhoa oa ho qhalakanya ha pigment ka resin e ka hlalosoa ka mehato e meraro e latelang: ea pele, resin e qhibilihisa bokaholimo ba li-pigment aggregates ebe e kenella ka har'a masoba a ka hare;Ea bobeli, kakaretso e robehile tlas'a tšusumetso le ho thulana pakeng tsa matla a ho kuta ka ntle le likaroloana tsa pigment;Qetellong, likaroloana tse sa tsoa thehoa tsa pigment li kolobisitsoe 'me li koahetsoe ke resin melt, e tsitsitseng ntle le agglomeration.Mehato ena e meraro e ka hlalosoa ka mokhoa o bonolo e le: lubrication - crushing - stabilization.

Resin e qhibilihisang e na le viscosity e phahameng le ho se tsamaisane hantle le bokaholimo ba pigment, ka hona ha e na metsi hantle ebile e thata ho kenella ka har'a li-pores tsa kakaretso, ka hona e ke ke ea fetisa matla a ho kuta 'me ho thata ho senya kakaretso.Esita le ka mor'a hore sehlopha se robehe, resin e qhibiliha ha e khone ho koloba ka potlako le ho sireletsa sebaka se secha, 'me ho kopana ho tla etsa hore likaroloana li kopane hape.Ho rarolla bothata bona, boka ba polyethylene bo ka ekeletsoa tsamaisong e ka holimo.Nakong ea ts'ebetso ea masterbatch system ka boka ba polyethylene, boka ba polyethylene e qala ho qhibiliha ka resin ebe e apesoa holim'a pigment.

Ka lebaka la viscosity ea eona e tlase le ho lumellana hantle le li-pigments, boka ba polyethylene bo bonolo ho kolobisa mebala le ho kenella ka har'a masoba a ka hare a lihlopha tsa pigment, ho fokotsa momahano, ho etsa hore li-pigment li bulehe habonolo tlas'a phello ea matla a ho kuta ka ntle, le likaroloana tse sa tsoa thehoa. e ka boela ea kolobisoa kapele le ho sireletsoa.Ho phaella moo, boka ba polyethylene bo ka phetha karolo ea ho fokotsa viscosity ea tsamaiso le ho ntlafatsa metsi.Ka hona, ho kenyelletsa boka ba polyethylene tlhahisong ea masterbatch ho ka ntlafatsa ts'ebetso ea tlhahiso, ho eketsa tlhahiso, le ho lumella khatello e phahameng ea pigment.
Qingdao Sainuo Chemical Co., Ltd.Re moetsi oa boka ba PE, boka ba PP, boka ba OPE, boka ba EVA, PEMA, EBS, Zinc/Calcium Stearate….Lihlahisoa tsa rona li fetile tlhahlobo ea REACH, ROHS, PAHS, FDA.
Kholiseha ka boka ba Sainuo, amohela potso ea hau!
