I-Dispersant iyi-ejenti ewusizo evame ukusetshenziswa ku-toner, esiza ukumanzisa umbala, ukunciphisa usayizi wezinhlayiya ze-pigment, futhi kwandise ukuhlobana phakathi kwe-resin ne-pigment, ngaleyo ndlela kuthuthukiswe ukuhambisana phakathi kombala kanye ne-resin carrier, kanye nokwenza ngcono. ukuhlakazwa kwe-pigment.Izinga.Enkambweni yokufanisa umbala, izinhlobo ezahlukene ze-dispersants zizothinta ikhwalithi yombala womkhiqizo.
Iphuzu lokuncibilika le-disperant ngokuvamile liphansi kunezinga lokushisa lokucubungula le-resin, futhi phakathi nenqubo yokubumba, liyancibilika ngaphambi kwe-resin, ngaleyo ndlela ikhulise uketshezi lwe-resin.Futhi ngenxa yokuthi i-dispersant ine-viscosity ephansi nokuhambisana okuhle ne-pigment, ingangena ku-pigment agglomerate, idlulise amandla angaphandle okugunda ukuze ivule i-pigment agglomerate, futhi ithole umphumela wokuhlakazeka okufanayo.
Kodwa-ke, uma isisindo se-molecular of the dispersant siphansi kakhulu futhi indawo yokuncibilika iphansi kakhulu, i-viscosity yesistimu izoncishiswa kakhulu, futhi amandla okugunda angaphandle adluliselwe kusuka kusampula kuya kuma-pigment agglomerate nawo azoncishiswa kakhulu, kunzima ukuvula izinhlayiya ze-agglomerated futhi izinhlayiya ze-pigment azikwazi ukuhlakazeka kahle.Ekuncibilikeni, ikhwalithi yombala yomkhiqizo ekugcineni ayigculisi.Lapho usebenzisa ama-dispersants enqubweni yokufanisa umbala, imingcele efana nesisindo samangqamuzana ahlobene nendawo yokuncibilika kufanele icatshangelwe, futhi ama-disperants afanele ama-pigments nama-resin othwala kufanele akhethwe.Ngaphezu kwalokho, uma inani le-disperant likhulu kakhulu, lizophinde libangele umbala womkhiqizo uphenduke ophuzi futhi kubangele ukuhlukana kwe-chromatic.
