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, ukubonakaliswa, ukuphindaphinda nokudluliswa kuyenzeka futhi, futhi umbala obonisiwe yizinhlayiya ze-pigment.Umbala obonisiwe.
Izindlela zokufaka imibala zepulasitiki ezivame ukusetshenziswa yilezi: umbala owomile, unamathisele umbala (unamathisele umbala) umbala, umbala we-masterbatch.
1. Umbala owomile
Indlela yokuxuba nemibala ngokuqondile nge-toner (izingulube noma odayi) enezela inani elifanele lezithasiselo eziyimpuphu nezinto zokusetshenziswa zepulasitiki kubizwa 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.Inqunyelwe inani;okubi ukuthi i-pigment izondiza uthuli futhi ibangele ukungcola ngesikhathi sokuthutha, ukugcinwa, ukukala nokuxuba, okuzothinta indawo yokusebenza kanye nempilo yabaqhubi.
2. Namathisela umbala wombala (unamathisele umbala) umbala
Endleleni yokunamathisela umbala, umbala uvame ukuxutshwa nomsizi wombala owuketshezi (i-plasticizer noma inhlaka) bese ugaywa ube unama, bese uhlanganiswa ngokulinganayo nepulasitiki, njengokunamathisela kombala koqweqwe lwawo, 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 ama-masterbatch ombala, izingulube zombala ezifanelekayo zivame ukulungiselelwa kuqala, bese izimibalabala zixutshwa kusithwali se-masterbatch sombala ngokwesilinganiso sefomula.Ama-molecule ahlanganiswe ngokugcwele, abese enziwa abe izinhlayiya ezinobukhulu obufana nezinhlayiya ze-resin, ezibe sezisetshenziswa imishini yokubumba ukwenza imikhiqizo yepulasitiki.Uma isetshenziswa, ingxenye encane kuphela (1%~4%) edinga ukungezwa kunhlaka enombala ukuze kufezwe injongo yombala.
Uma kuqhathaniswa nombala owomile, umbala we-masterbatch unezinzuzo ezilandelayo ezisobala: ukuthuthukisa ukungcoliswa kwemvelo okubangelwa i-flying toner, ukushintsha umbala kalula ngesikhathi sokusetshenziswa, akukho ukuhlanzwa okukhethekile kwe-extruder hopper, kanye nefomula ezinzile Inokusebenza okuqinile futhi ingaqinisekisa ukuthi umbala amaqoqo amabili ama-masterbatches ombala wohlobo olufanayo ahlala ezinzile.Ububi bombala we-masterbatch ukuthi izindleko zokufaka imibala ziphezulu futhi nenani lokulungiselela aliguquki.Ngaphezu kwalokho, i-pearlescent toner, izimpushana ze-fluorescent, izimpushana ezikhanyayo namanye amathoni enziwa abe ama-masterbatches ombala bese esetshenziselwa ukufaka imibala kumapulasitiki.Uma kuqhathaniswa nokuxuba ngokuqondile amapulasitiki ukuze kufakwe umbala, umphumela (ofana ne-gloss, njll.) uyancipha cishe ngo-10%, futhi imikhiqizo yokubumba umjovo nayo ijwayele ukugeleza imigqa.Imivimbo nemithungo.
