Feem ntau siv cov txheej txheem xim yas

Thaum lub teeb ua rau cov khoom yas, ib feem ntawm lub teeb yog reflected los ntawm qhov chaw ntawm cov khoom los tsim cov luster, thiab lwm qhov ntawm lub teeb yog refracted thiab xa mus rau sab hauv ntawm cov yas.Thaum ntsib cov xim pigment, kev xav, refraction thiab kis tau tshwm sim dua, thiab cov xim uas pom yog xim xim.Cov xim reflected los ntawm cov khoom.

Feem ntau siv cov xim xim yas yog: xim qhuav, xim xim xim (xim paste) xim, xim masterbatch xim.

1. Cov xim qhuav
Txoj kev ncaj qha siv cov toner (pigments lossis dyes) txhawm rau ntxiv qhov tsim nyog ntawm cov hmoov additives thiab cov ntaub ntawv yas rau kev sib xyaw thiab xim yog hu ua cov xim qhuav.
Qhov zoo ntawm cov xim qhuav yog qhov zoo dispersibility thiab tus nqi qis.Nws tuaj yeem raug teev tseg raws li kev xav tau, thiab kev npaj tau yooj yim heev.Nws txuag cov neeg siv khoom thiab cov khoom siv hauv kev ua cov xim xws li xim masterbatches thiab xim pastes, yog li tus nqi qis, thiab cov neeg yuav khoom thiab cov muag khoom tsis tas yuav siv nws.Kev txwv los ntawm tus nqi: Qhov tsis zoo yog tias cov xim yuav muaj plua plav ya thiab muaj kuab paug thaum thauj, khaws cia, hnyav thiab sib tov, uas yuav cuam tshuam rau kev ua haujlwm thiab kev noj qab haus huv ntawm cov neeg ua haujlwm.
2. Paste colorant (xim paste) xim
Nyob rau hauv txoj kev muab tshuaj pleev xim, cov xim feem ntau yog tov nrog cov kua xim xim (plasticizer los yog resin) los ua ib qho muab tshuaj txhuam, thiab tom qab ntawd nws yuav sib npaug nrog cov yas, xws li cov xim pleev xim rau cov kua nplaum nplaum, xim, thiab lwm yam.
Qhov kom zoo dua ntawm pasty colorant (xim paste) xim yog tias cov nyhuv dispersion zoo, thiab cov plua plav paug yuav tsis tsim;qhov tsis zoo yog tias tus nqi ntawm cov xim tsis yooj yim rau kev suav thiab tus nqi siab.
3. Masterbatch xim
Thaum npaj cov xim masterbatch, cov xim uas tsim nyog feem ntau yog npaj ua ntej, thiab tom qab ntawd cov xim sib xyaw ua ke rau hauv cov xim masterbatch carrier raws li tus qauv piv.Cov khoom sib xyaw ua ke tag nrho, thiab tom qab ntawd ua rau cov khoom zoo sib xws rau cov khoom siv resin, thiab tom qab ntawd siv cov khoom siv molding los ua cov khoom yas.Thaum siv, tsuas yog ib feem me me (1% mus rau 4%) yuav tsum tau ntxiv rau cov xim pleev xim kom ua tiav lub hom phiaj ntawm cov xim.
