Hydroxyethyl cellulose ether, ib yam khoom siv tsis yog ionic surfactant, yog ib qho cellulose ether organic water-based ink thickener uas feem ntau siv. Nws yog ib qho tshuaj non-ionic uas yaj tau hauv dej thiab muaj peev xwm ua kom tuab zoo rau hauv dej.
Nws muaj ntau yam ntxwv xws li thickening, floating, bonding, emulsifying, zaj duab xis-tsim, concentrating, tiv thaiv dej los ntawm evaporation, tau txais thiab xyuas kom meej cov dej num ntawm cov khoom me me, thiab kuj muaj ntau yam khoom tshwj xeeb.
Cov tshuaj dispersant
Ib tug dispersant yog ib tug surfactant uas muaj ob qho kev sib txawv ntawm lipophilicity thiab hydrophilicity hauv lub molecule. Nws tuaj yeem sib npaug cov khoom khov thiab kua ntawm cov inorganic thiab organic pigments uas nyuaj rau yaj hauv kua, thiab tib lub sijhawm tiv thaiv cov khoom me me los ntawm kev sib sau ua ke thiab agglomerating, tsim ib tug amphiphilic neeg sawv cev uas yuav tsum tau rau ib tug ruaj khov suspension.
Nrog cov tshuaj dispersant, nws tuaj yeem txhim kho qhov ci ntsa iab, tiv thaiv cov xim ntab, thiab txhim kho lub zog tinting. Nco ntsoov tias lub zog tinting tsis siab li sai tau hauv lub kaw lus xim tsis siv neeg, txo qhov viscosity, nce qhov kev thauj khoom ntawm cov xim, thiab lwm yam.
D
Tus neeg sawv cev ntub dej ua lub luag haujlwm tseem ceeb hauv lub kaw lus txheej, uas tuaj yeem ncav cuag qhov chaw ntawm lub substrate ua ntej kom "pave txoj kev", thiab tom qab ntawd cov khoom tsim zaj duab xis tuaj yeem nthuav dav raws "txoj kev" uas tus neeg sawv cev ntub dej tau mus ncig. Hauv lub kaw lus dej, tus neeg sawv cev ntub dej yog qhov tseem ceeb heev, vim tias qhov nro ntawm qhov chaw ntawm dej siab heev, ncav cuag 72 dynes, uas siab dua qhov nro ntawm qhov chaw ntawm lub substrate. Ntws kis.
Tus neeg sawv cev tiv thaiv kev ua npuas ncauj
Cov tshuaj ua npuas ncauj tseem hu ua defoamer, antifoaming agent, thiab cov tshuaj ua npuas ncauj txhais tau tias tshem tawm cov npuas ncauj. Nws yog ib yam khoom uas muaj qhov nruj ntawm qhov chaw qis thiab muaj kev ua haujlwm ntawm qhov chaw siab, uas tuaj yeem tswj lossis tshem tawm cov npuas ncauj hauv lub kaw lus. Yuav muaj ntau cov npuas ncauj tsis zoo hauv cov txheej txheem tsim khoom lag luam, uas ua rau kev nce qib ntawm kev tsim khoom tsis zoo. Lub sijhawm no, nws yog qhov tsim nyog los ntxiv cov tshuaj ua npuas ncauj kom tshem tawm cov npuas ncauj tsis zoo no.
Titanium dioxide
Kev lag luam pleev xim yog cov neeg siv titanium dioxide ntau tshaj plaws, tshwj xeeb tshaj yog rutile titanium dioxide, feem ntau yog siv los ntawm kev lag luam pleev xim. Cov xim ua los ntawm titanium dioxide muaj xim ci, muaj zog zais tau zoo, muaj zog tinting zoo, siv tshuaj tsawg, thiab ntau yam. Nws tuaj yeem tiv thaiv kev ruaj khov ntawm cov khoom nruab nrab, thiab tuaj yeem txhim kho lub zog kho tshuab thiab kev nplaum ntawm cov zaj duab xis pleev xim kom tiv thaiv kev tawg. Tiv thaiv cov duab UV thiab cov dej noo kom tsis txhob nkag mus, ua rau lub neej ntawm cov zaj duab xis pleev xim ntev dua.
Kaolin
Kaolin yog ib hom tshuaj filler. Thaum siv rau hauv cov txheej txheej, nws lub luag haujlwm tseem ceeb yog: filling, ua kom tuab ntawm cov xim pleev xim, ua rau cov xim pleev xim plump thiab khov kho; txhim kho kev hnav tsis kam thiab kev ruaj khov; kho cov khoom siv kho qhov muag ntawm cov txheej txheej, hloov qhov tsos ntawm cov txheej txheej; ua ib qho filler hauv cov txheej txheej, nws tuaj yeem txo cov resin siv thiab txo cov nqi tsim khoom; nws ua lub luag haujlwm coj ua hauv cov khoom siv tshuaj ntawm cov txheej txheej, xws li txhim kho kev tiv thaiv xeb thiab hluav taws kub.
cov calcium hnyav
Thaum siv cov calcium ntau rau hauv cov xim pleev tsev sab hauv, nws tuaj yeem siv ib leeg lossis ua ke nrog hmoov talcum. Piv nrog talc, cov calcium ntau tuaj yeem txo qhov nrawm ntawm kev pleev xim, txhim kho kev khaws xim ntawm cov xim dawb thiab ua kom muaj kev tiv thaiv pwm.
Tshuaj pleev
Lub luag haujlwm ntawm cov emulsion yog los npog cov xim thiab cov khoom sau tom qab tsim cov zaj duab xis (cov hmoov uas muaj peev xwm xim zoo yog cov xim, thiab cov hmoov uas tsis muaj peev xwm xim yog cov khoom sau) kom tiv thaiv cov hmoov tshem tawm. Feem ntau, styrene-acrylic thiab cov emulsions acrylic ntshiab yog siv rau phab ntsa sab nraud. Styrene-acrylic yog tus nqi tsim nyog, yuav tig daj, acrylic ntshiab muaj kev tiv thaiv huab cua zoo thiab khaws xim, thiab tus nqi siab dua me ntsis. Feem ntau, styrene-acrylic emulsion yog siv rau cov xim phab ntsa sab nraud qis, thiab acrylic emulsion ntshiab feem ntau yog siv rau cov xim phab ntsa sab nraud nruab nrab thiab siab.
