Mokhoa oa tlhahiso ea masterbatch

Litlhoko tsa ts'ebetso ea tlhahiso ea masterbatch ea mebala li thata haholo, 'me mokhoa oa ho koloba o sebelisoa ka kakaretso.'Mala masterbatch ke fatše' me mokhahlelo-inverted ke metsi, 'me letoto la liteko li lokela ho etsoa ha pigment e ntse e siloa, joalo ka qeto ea bokhabane, ts'ebetso ea ho hasana, litaba tse tiileng le pente ea mebala e metle ea seretse sa sanding.

Ho na le mekhoa e mene ea tlhahiso ea metsi bakeng sa masterbatch ea mebala: mokhoa oa ho hlatsoa, ​​mokhoa oa ho luba, mokhoa oa sesepa sa tšepe, le mokhoa oa enke.
(1) Mokhoa oa ho hlatsoa: Pigment, metsi le dispersant li entsoe ka lehlabathe ho etsa hore pigment e be nyane ho feta 1pm, 'me pigment e fetisetsoa karolong ea oli ka mokhoa oa phetisetso ea mohato, ebe e omisoa ho fumana masterbatch ea mebala.Li-solvents tsa tlhaho le lisebelisoa tse lumellanang tsa ho hlaphoheloa ha solvent lia hlokahala bakeng sa phetoho ea mohato.Mokhoa ona o tjena:
Pigment, dispersant, a thusang chelete - bolo leloala - homogenization le ho tsitsisa kalafo - ho omisa - ho kopanya resin - extrusion granulation color masterbatch
(2) Mokhoa oa ho luba Mokhoa oa ho phalla oa mokhoa oa ho luba ke o latelang:
Pigment, lithuso, ho luba resin - dehydration - ho omisa - ho kopanya resin - extrusion granulation ho masterbatch
(3) Mokhoa oa tšepe oa sesepa sa pigment o siloa ka boholo ba karoloana e ka bang 1um, 'me tharollo ea sesepa e eketsoa ka mocheso o itseng ho etsa hore bokaholimo ba likaroloana tsa pigment bo kolobisoe ka tharollo ea sesepa ho etsa moalo oa tharollo ea saponification. .Eketsa tharollo ea letsoai ea tšepe le holim'a pigment.Lera la saponification ka lik'hemik'hale le itšoara ho etsa lesela le sireletsang la sesepa sa tšepe (magnesium stearate), e le hore likaroloana tsa pigment tse fatše ha li thekesele.

Mokhoa oa ho phalla oa sesepa sa tšepe ke ka tsela e latelang:
Pigment, lithuso, motsoako oa metsi - karohano le dehydration - ho omisa - ho kopanya resin - extrusion granulation ho masterbatch
(4) Mokhoa oa enke Ha ho etsoa masterbatch ea mebala, ho sebelisoa mokhoa oa tlhahiso ea pente ea mebala ea enke, ke hore, ka ho sila ka meqolo e meraro, lesela le tlase la tšireletso la molek'hule le koahetsoe holim'a pigment.Motsoako o motle oa peista o kopantsoe le resin ea carrier, ebe o etsoa polasetiki ka leloala la twin-roll, 'me qetellong o granulated ka sekoahelo se le seng kapa se-fahla-screw extruder.
Phallo ea ts'ebetso e tjena:
Li-pigments, li-additives, li-disperants, li-resin, metsoako ea mokelikeli - pente ea mebala e meraro ea leloala - desolventizing - ho kopanya resin - extrusion granulation into masterbatch.
Ts'ebetso ea tlhahiso e omileng ea masterbatch ea mebala: pigment (kapa dae) e thusang, dispersant, carrier - ho kopanya ka lebelo le phahameng, ho hlohlelletsa le ho kuta - twin-screw extrusion granulation - ho itšeha le granulation ka har'a colorbatch.
