Kana chiedza chichishanda pane zvigadzirwa zvepurasitiki, chikamu chechiedza chinoratidzwa kubva pamusoro pechigadzirwa kuti chibudise kupenya, uye chimwe chikamu chechiedza chinodzorwa uye chinoparidzirwa mukati mepurasitiki.Paunenge uchisangana ne pigment particles, kuratidzira, refraction uye kutapurirana kunoitika zvakare, uye inoratidzwa ruvara ndiyo pigment.Ruvara rwunoratidzwa nezvidimbu.
Inowanzo shandiswa mapurasitiki ekupenda nzira ndeaya: yakaoma coloring, paste colorant (color paste) coloring, color masterbatch coloring.
1. Dry coloring
Iyo nzira yekushandisa zvakananga toner (pigments kana dhayi) kuwedzera huwandu hwakakodzera hwehupfu hwekuwedzera uye epurasitiki mbishi zvinhu zvekusanganisa uye kupenda kunonzi yakaoma coloring.
Zvakanakira kuoma kwemavara akanaka dispersibility uye mutengo wakaderera.Inogona kutsanangurwa zvisina tsarukano maererano nezvinodiwa, uye kugadzirira kuri nyore kwazvo.Iyo inochengetedza kushandiswa kwevashandi uye zviwanikwa zvekushandisa mukugadziriswa kwemavara akadai semavara masterbatches uye mavara anonamira, saka mutengo wakaderera, uye vatengi nevatengesi havafanirwe kuishandisa.Kudziviswa nehuwandu: Izvo zvisingabatsiri ndezvokuti pigment ichava neguruva rinobhururuka uye kusvibiswa panguva yekufambisa, kuchengetedza, kuyera uye kusanganiswa, izvo zvichakanganisa nzvimbo yekushanda uye hutano hwevashandi.
2. Namira colorant (color paste) coloring
Munzira yekuisa mavara, iyo colorant inowanzosanganiswa neyekuyerera yemvura yekubatsira (plasticizer kana resin) kugadzira paste, uyezve inosanganiswa zvakaenzana nepurasitiki, senge color paste yeshuga glue, pendi, nezvimwe.
Kubatsira kwepasty colorant (ruvara paste) ruvara ndeyekuti kupararira mhedzisiro yakanaka, uye kusvibiswa kweguruva hakuzoumbwa;chakashata ndechekuti huwandu hwemavara hahusi nyore kuverenga uye mutengo wakakwira.
3. Masterbatch coloring
Paunenge uchigadzira masterbatch colorbatch, iyo inokwanisa ruvara pigment inowanzo gadzirirwa kutanga, uye ipapo iyo pigment inosanganiswa muvara masterbatch carrier zvinoenderana neformula reshiyo.Izvo zvimedu zvinosanganiswa zvizere, uye zvobva zvaitwa kuita zvidimbu zvakafanana muhukuru kune resin zvimedu, zvobva zvashandiswa kugadzira michina yekugadzira zvigadzirwa zvepurasitiki.Kana ichishandiswa, chikamu chidiki chete (1% kusvika 4%) chinoda kuwedzerwa kune resin ine ruvara kuti uwane chinangwa chekupenda.
