Dispersant inowanzoshandiswa mubatsiri mu toner, iyo inobatsira kunyorovesa pigment, kuderedza saizi ye pigment, uye kuwedzera hukama pakati pe resin ne pigment, nekudaro kuvandudza kuwirirana pakati pe pigment uye resin inotakura, nekuvandudza. kupararira kwe pigment.Level.Mukuita kwekufananidza kwemavara, marudzi akasiyana-siyana ekuparadzira achakanganisa kunaka kwemavara echigadzirwa.
Nzvimbo yekunyunguduka yeanoparadzira kazhinji yakadzikira pane tembiricha yekugadzira resin, uye panguva yekuumbwa, inonyungudika pamberi peresin, nekudaro ichiwedzera kuyerera kweresin.Uye nekuti iyo inoparadzira ine yakaderera viscosity uye kuenderana kwakanaka ne pigment, inogona kupinda mu pigment agglomerate, kutamisa ekunze shear simba kuvhura pigment agglomerate, uye kuwana yunifomu yekuparadzira maitiro.
Nekudaro, kana huremu hwema molecular ye dispersant yakadzikira uye nzvimbo yekunyunguduka yakadzikira, viscosity yehurongwa ichadzikiswa zvakanyanya, uye simba rekunze reshear rinotamiswa kubva kumuenzaniso kuenda kune pigment agglomerates richaderedzwa zvakanyanya, zvichiita. zvakaoma kuvhura ma agglomerated particles uye pigment particles haigone kuparadzirwa zvakanaka.Mukunyunguduka, ruvara rwemhando yechigadzirwa hachina kugutsikana.Paunenge uchishandisa ma disperants mukufananidza kwemavara maitiro, maparamendi akadai seakaenzana mamorekuru huremu uye nzvimbo yekunyungudika inofanirwa kutariswa, uye ma dispersants akakodzera pigment uye anotakura resin anofanirwa kusarudzwa.Uye zvakare, kana huwandu hwekuparadzira hwakanyanya, huchaitawo kuti ruvara rwechigadzirwa ruite yero uye kukonzera chromatic aberration.
