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.
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 sib xyaw thiab pleev xim ncaj qha nrog toner (pigments lossis dyes) ntxiv cov khoom tsim nyog ntawm cov hmoov additives thiab cov ntaub ntawv yas yog hu ua qhuav xim.
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.Nws yog txwv los ntawm tus nqi;qhov tsis zoo yog tias cov xim yuav ya cov plua plav thiab ua rau 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 auxiliary (plasticizer los yog resin) thiab hauv av rau hauv ib qho muab tshuaj txhuam, thiab tom qab ntawd nws sib npaug nrog cov yas, xws li xim muab tshuaj txhuam rau enamel, 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 masterbatches, 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 molecules tau tag nrho ua ke, thiab tom qab ntawd ua rau cov khoom zoo sib xws rau cov khoom siv resin, uas yog siv los ntawm cov khoom siv molding los ua cov khoom yas.Thaum siv, tsuas yog ib feem me me (1% ~ 4%) yuav tsum tau ntxiv rau cov xim pleev xim kom ua tiav lub hom phiaj ntawm cov xim.
Piv nrog rau cov xim qhuav, xim masterbatch muaj cov txiaj ntsig zoo hauv qab no: kev txhim kho cov pa phem ib puag ncig los ntawm ya toner, hloov xim yooj yim thaum siv, tsis muaj kev tu tshwj xeeb ntawm extruder hopper, thiab cov qauv ruaj khov Nws muaj kev ua tau zoo thiab tuaj yeem xyuas kom meej tias cov xim ntawm ob pawg ntawm cov xim masterbatches ntawm tib lub hom tseem nyob ruaj khov.Qhov tsis zoo ntawm cov xim masterbatch yog tias cov xim xim yog siab thiab qhov kev npaj kom muaj nuj nqis tsis hloov pauv.Tsis tas li ntawd, pearlescent toners, fluorescent hmoov, luminous hmoov thiab lwm yam toners yog ua rau cov xim masterbatches thiab ces siv rau xim yas.Piv nrog rau cov khoom sib xyaw ncaj qha rau cov xim, cov nyhuv (xws li gloss, thiab lwm yam) tsis muaj zog li ntawm 10%, thiab cov khoom txhaj tshuaj molding kuj muaj cov kab ntws.Stripes thiab seams.
