Uma ukukhanya kusebenza emikhiqizweni yepulasitiki, ingxenye yokukhanya ibonakala ebusweni bomkhiqizo ukuze ikhiqize ukucwebezela, futhi enye ingxenye yokukhanya iyaphikiswa futhi idluliselwe ngaphakathi kwepulasitiki.Lapho uhlangabezana nezinhlayiya ze-pigment, i-refraction, i-refraction kanye nokudluliselwa kuyenzeka futhi, futhi umbala obonisiwe i-pigment.Umbala oboniswa yizinhlayiya.
Izindlela zokufaka imibala zepulasitiki ezivame ukusetshenziswa yilezi: umbala owomile, unamathisele umbala (unamathisele umbala) umbala, umbala we-masterbatch.
1. Umbala owomile
Indlela yokusebenzisa ngokuqondile i-toner (izingulube noma odayi) ukwengeza inani elifanele lezithasiselo eziyimpuphu nezinto zokusetshenziswa zepulasitiki zokuxuba nemibala ibizwa ngokuthi umbala owomile.
Izinzuzo zombala owomile yi-dispersibility enhle kanye nezindleko eziphansi.Ingacaciswa ngokungenasisekelo ngokwezidingo, futhi ukulungiswa kulula kakhulu.Igcina ukusetshenziswa kwabasebenzi kanye nezinsizakusebenza ekucubungulweni kombala njengama-masterbatches ombala nokunamathisela kombala, ngakho-ke izindleko ziphansi, futhi abathengi nabathengisi akudingeki bayisebenzise.Ikhawulelwe inani: Okubi ukuthi i-pigment izoba nothuli olundizayo kanye nokungcola ngesikhathi sokuthutha, ukugcinwa, ukukala nokuxutshwa, okuzothinta indawo yokusebenza kanye nempilo yabaqhubi.
2. Namathisela umbala wombala (unamathisele umbala) umbala
Endleleni yokunamathisela umbala, umbala uvame ukuxutshwa nomsizi wombala we-liquid (i-plasticizer noma i-resin) ukuze wenze unamathisele, bese uhlanganiswa ngokulinganayo nepulasitiki, njengokunamathisela umbala weglue ushukela, upende, njll.
Inzuzo yombala we-pasty (unamathisele umbala) umbala ukuthi umphumela wokuhlakazeka muhle, futhi ukungcola kothuli ngeke kwakhiwe;okubi ukuthi inani lombala akulula ukubala futhi izindleko ziphezulu.
3. Umbala we-Masterbatch
Lapho ulungiselela i-masterbatch yombala, i-pigment yombala efanelekayo ivame ukulungiswa kuqala, bese i-pigment ixutshwa kusithwali se-masterbatch sombala ngokwesilinganiso sefomula.Izinhlayiya zihlanganiswe ngokugcwele, bese zenziwa izinhlayiya ezifanayo ngosayizi wezinhlayiya ze-resin, bese zisetshenziselwa imishini yokubumba ukwenza imikhiqizo yepulasitiki.Lapho isetshenziswa, ingxenye encane kuphela (1% kuya ku-4%) edinga ukungezwa kunhlaka enombala ukuze kufezwe injongo yokubala.
