Xa ukukhanya kusebenza kwiimveliso zeplastiki, inxalenye yokukhanya ibonakaliswa ukusuka kumphezulu wemveliso ukuvelisa i-luster, kwaye enye inxalenye yokukhanya iyachithwa kwaye idluliselwe ngaphakathi kweplastiki.Xa udibana namasuntswana e-pigment, imbonakalo, i-refraction kunye nokuhanjiswa kwenzeka kwakhona, kwaye umbala obonisiweyo yi-pigment.Umbala obonakaliswa ngamasuntswana.
Iindlela zokufaka imibala zeplastiki ezixhaphakileyo zezi: umbala owomileyo, ncamathelisa umbala (cola umbala) umbala, umbala we-masterbatch.
1. Umbala owomileyo
Indlela yokusebenzisa ngokuthe ngqo i-toner (i-pigments okanye idayi) ukongeza inani elifanelekileyo lezongezo ze-powdery kunye nezixhobo zeplastiki zokuxuba kunye nombala kuthiwa ngumbala owomileyo.
Iinzuzo zombala owomileyo zi-dispersibility ezilungileyo kunye neendleko eziphantsi.Inokucaciswa ngokungqongqo ngokweemfuno, kwaye ukulungiswa kukulungele kakhulu.Igcina ukusetyenziswa kwabasebenzi kunye nezixhobo eziphathekayo ekuqhutyweni kwemibala efana ne-masterbatches yombala kunye ne-pastes yombala, ngoko ixabiso liphantsi, kwaye abathengi kunye nabathengisi abafuni ukuyisebenzisa.Ukunqandwa yimali: Ukungalungi kukuba i-pigment iya kuba nothuli olubhabha kunye nokungcola ngexesha lokuthutha, ukugcinwa, ukulinganisa kunye nokuxuba, okuya kuchaphazela indawo yokusebenza kunye nempilo yabaqhubi.
2. Ncamathelisa umbala (coca umbala) umbala
Kwindlela yokunamathisela umbala, umbala udla ngokuxutywa kunye nomsizi wombala we-liquid (i-plasticizer okanye i-resin) ukwenza i-paste, kwaye ixutywe ngokulinganayo kunye neplastiki, njengombala wombala weglue, ipeyinti, njl.
Inzuzo yombala we-pasty (umbala wokunamathisela) umbala kukuba umphumo wokusabalalisa ulungile, kwaye ukungcola kothuli akuyi kwenziwa;ukungalunganga kukuba isixa sombala akulula ukubala kwaye iindleko ziphezulu.
3. Umbala we-Masterbatch
Xa ulungiselela i-masterbatch yombala, i-pigment yombala ofanelekileyo idla ngokulungiswa kuqala, emva koko i-pigment ixutywe kumbala ophethe i-masterbatch ngokwe-formula ratio.Amasuntswana adityaniswe ngokupheleleyo, kwaye emva koko ayenziwe amasuntswana afana nobungakanani kwi-resin particles, aze asetyenziswe kwizixhobo zokubumba ukwenza iimveliso zeplastiki.Xa isetyenziswe, kuphela inxalenye encinci (1% ukuya kwi-4%) kufuneka ifakwe kwi-resin enemibala ukufezekisa injongo yombala.
