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 ngamasuntswana e-pigment.Umbala obonakalisiweyo.
Iindlela zokufaka imibala zeplastiki ezixhaphakileyo zezi: umbala owomileyo, ncamathelisa umbala (cola umbala) umbala, umbala we-masterbatch.
1. Umbala owomileyo
Indlela yokuxuba kunye nemibala ngokuthe ngqo kunye ne-toner (i-pigments okanye idayi) ukongeza inani elifanelekileyo lezongezo zomgubo kunye nezixhobo zeplastiki eziluhlaza 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.Inqunyulwa yimali;ukungahambi kakuhle kukuba i-pigment iya kubhabha uthuli kwaye ibangele ukungcola ngexesha lokuthutha, ukugcinwa, ukulinganisa kunye nokuxuba, okuya kuchaphazela indawo yokusebenza kunye nempilo yabaqhubi.
2. Ncamathelisa umbala (coca umbala) umbala
Kwindlela yokunamathisela umbala, umbala uvame ukuxutywa kunye nomsizi wombala we-liquid (iplastiki okanye i-resin) kunye nomhlaba kwi-paste, emva koko ixutywe ngokulinganayo kunye neplastiki, njengombala we-enamel, 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 ii-masterbatches zombala, ii-pigments zombala ezifanelekileyo zidla ngokulungiswa kuqala, emva koko ii-pigments zixutywe kumbala we-masterbatch carrier ngokwe-formula ratio.Iimolekyuli zidityaniswe ngokupheleleyo, kwaye emva koko zenziwe ngamasuntswana afana nobukhulu kumasuntswana entlaka, athi ke asetyenziswe zizixhobo zokubumba ukwenza iimveliso zeplastiki.Xa isetyenziswe, kuphela inxalenye encinci (1% ~ 4%) kufuneka ifakwe kwi-resin enemibala ukufezekisa injongo yombala.
Xa kuthelekiswa nombala owomileyo, umbala we-masterbatch unezi nzuzo zilandelayo: ukuphucula ukungcoliseka kwendalo okubangelwa yi-flying toner, ukutshintsha umbala ngokulula ngexesha lokusetyenziswa, akukho ukucocwa okukhethekileyo kwe-extruder hopper, kunye nefomula ezinzileyo Isebenza ngamandla kwaye inokuqinisekisa ukuba umbala iibhetshi ezimbini ze-masterbatches zombala zohlobo olufanayo zihlala zizinzile.Ukungalungi kombala we-masterbatch kukuba ixabiso lombala liphezulu kwaye ubungakanani bokulungiselela abuguquki.Ukongeza, iitoni zepearlescent, umgubo wefluorescent, umgubo okhanyayo kunye nezinye iitoni zenziwe zibe zii-masterbatches zombala kwaye emva koko zisetyenziselwa ukwenza imibala kwiiplastiki.Xa kuthelekiswa nokuxuba ngokuthe ngqo iiplastiki zombala, umphumo (ofana neglosi, njl. njl.) Ubuthathaka malunga ne-10%, kunye neemveliso zokubumba inaliti nazo zilungele ukuhamba imigca.Imivumbo kunye nemithungo.
