I-Dispersant yinto esetyenziswa ngokuqhelekileyo encedisayo kwi-toner, enceda ukumanzisa i-pigment, ukunciphisa ubungakanani besuntswana le-pigment, kunye nokwandisa ubudlelwane phakathi kwe-resin kunye ne-pigment, ngaloo ndlela iphucula ukuhambelana phakathi kwe-pigment kunye ne-carrier resin, kunye nokuphucula. ukusasazwa kwebala.Inqanaba.Kwinkqubo yokudibanisa umbala, iintlobo ezahlukeneyo ze-dispersants ziya kuchaphazela umgangatho wombala wemveliso.
Indawo yokunyibilika ye-dispersant ngokuqhelekileyo iphantsi kunokushisa kwe-resin, kwaye ngexesha lenkqubo yokubumba, iyancibilika phambi kwe-resin, ngaloo ndlela inyusa ubuninzi be-resin.Kwaye ngenxa yokuba i-dipersant ine-viscosity ephantsi kunye nokuhambelana kakuhle kunye ne-pigment, inokungena kwi-pigment agglomerate, idlulise amandla angaphandle okucheba ukuvula i-pigment agglomerate, kwaye ifumane isiphumo sokusasazeka okufanayo.
Nangona kunjalo, ukuba ubunzima be-molecular of dispersant buphantsi kakhulu kwaye indawo yokunyibilika iphantsi kakhulu, i-viscosity yenkqubo iya kuncitshiswa kakhulu, kwaye i-shear force yangaphandle edluliselwe kwisampuli ukuya kwi-pigment agglomerates nayo iya kuncitshiswa kakhulu. Kunzima ukuvula iincinci ze-agglomerated kunye ne-pigment particles ayikwazi ukuchithwa kakuhle.Kwi-melting, umgangatho wombala wemveliso ekugqibeleni awunelisekanga.Xa usebenzisa i-dispersants kwinkqubo yokudibanisa umbala, iiparitha ezinjengobunzima be-molecular kunye ne-melting point kufuneka ziqwalaselwe, kunye ne-dispersants ezifanelekileyo kwii-pigments kunye ne-resin carrier kufuneka zikhethwe.Ukongeza, ukuba inani le-dispersant likhulu kakhulu, liya kubangela ukuba umbala wemveliso ujike ube tyheli kwaye ubangele ukuphambuka kwechromatic.
