Hydroxyethyl Cellulose Ether
Hydroxyethyl cellulose ether, uas tsis yog-ionic nto active tshuaj, yog ib tug nquag siv cellulose ether organic water-based number case thickener. Nws yog cov dej-soluble non-ionic compound thiab muaj peev xwm thickening zoo rau dej.
Nws muaj ntau yam ntxwv xws li thickening, floating, bonding, emulsifying, film-forming, concentrating, tiv thaiv dej los ntawm evaporation, tau txais thiab xyuas kom meej cov kev ua ntawm hais, thiab kuj muaj ntau yam khoom tshwj xeeb.
Dispersant
Ib tug dispersant yog ib tug surfactant uas muaj ob yam khoom ntawm lipophilicity thiab hydrophilicity nyob rau hauv lub molecule. Nws tuaj yeem sib cais cov khoom thiab cov kua ua kua ntawm cov xim tsis muaj zog thiab cov organic pigments uas nyuaj rau yaj hauv cov kua, thiab tib lub sijhawm tiv thaiv cov khoom los ntawm kev sib haum xeeb thiab agglomerating, tsim ib tus neeg sawv cev amphiphilic xav tau rau kev ncua kev ruaj ntseg.
Nrog cov dispersant, nws tuaj yeem txhim kho qhov ci, tiv thaiv cov xim ntab, thiab txhim kho lub zog tinting. Nco ntsoov tias lub zog tinting tsis yog siab npaum li qhov ua tau nyob rau hauv cov xim tsis siv neeg, txo cov viscosity, nce cov khoom ntawm cov xim, thiab lwm yam.
Tus neeg saib dej ntub dej
Tus neeg sawv cev ntub dej ua lub luag haujlwm hauv lub luag haujlwm hauv txheej txheej txheej txheej, uas tuaj yeem ncav cuag qhov chaw ntawm lub substrate ua ntej "txhim txoj kev", thiab tom qab ntawd cov yeeb yaj kiab tsim tuaj yeem kis tau raws "txoj kev" uas tus neeg sawv cev ntub dej tau mus. Nyob rau hauv cov dej-raws li system, tus neeg sawv cev ntub dej yog ib qho tseem ceeb heev, vim hais tias qhov nro ntawm cov dej yog siab heev, ncav cuag 72 dynes, uas yog ntau dua qhov nro ntawm lub substrate. Tshaj tawm.
Antifoaming tus neeg sawv cev
Defoamer tseem hu ua defoamer, antifoaming agent, thiab foaming agent tiag tiag txhais tau tias tshem tawm npuas. Nws yog ib yam khoom uas tsis tshua muaj qhov nro thiab kev ua haujlwm siab, uas tuaj yeem cuam tshuam lossis tshem tawm cov npuas dej hauv lub cev. Muaj ntau yam teeb meem foams yuav raug tsim nyob rau hauv cov txheej txheem kev tsim khoom, uas cuam tshuam qhov kev nce qib ntawm kev tsim khoom. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tau ntxiv ib qho defoamer kom tshem tawm cov npuas dej tsis zoo no.
Titanium dioxide
Kev lag luam xim yog cov neeg siv ntau tshaj plaws ntawm titanium dioxide, tshwj xeeb tshaj yog rutile titanium dioxide, feem ntau yog siv los ntawm kev lag luam xim. Cov xim ua los ntawm titanium dioxide muaj cov xim ci, lub zog zais siab, lub zog tinting muaj zog, tsawg npaum li cas, thiab ntau yam. Nws tuaj yeem tiv thaiv kev ruaj ntseg ntawm qhov nruab nrab, thiab tuaj yeem txhim kho lub zog txhua yam thiab adhesion ntawm cov xim zaj duab xis los tiv thaiv cov kab nrib pleb. Tiv thaiv UV rays thiab ya raws los ntawm kev nkag mus, ua kom lub neej ntawm cov xim pleev xim rau lub neej ntev.
Kaolin
Kaolin yog ib hom kev muab tub lim. Thaum siv cov coatings, nws lub luag haujlwm tseem ceeb yog: txhaws, ua kom lub thickness ntawm cov xim zaj duab xis, ua rau cov xim zaj duab xis ntau plump thiab khoom; txhim kho hnav tsis kam thiab durability; kho cov khoom kho qhov muag ntawm cov txheej txheem, hloov Cov tsos ntawm txheej zaj duab xis; raws li ib tug muab tub lim nyob rau hauv lub txheej, nws yuav txo tau tus nqi ntawm resin siv thiab txo tus nqi ntau lawm; nws plays lub luag haujlwm tseem ceeb hauv cov khoom siv tshuaj lom neeg ntawm cov yeeb yaj kiab txheej, xws li kev txhim kho cov xeb thiab nplaim hluav taws.
hnyav calcium
Thaum cov calcium hnyav siv rau hauv cov xim tha xim sab hauv, nws tuaj yeem siv ib leeg lossis ua ke nrog talcum hmoov. Piv nrog rau talc, hnyav calcium tuaj yeem txo qhov chalking tus nqi, txhim kho cov xim tuav ntawm cov xim xim xim thiab ua rau muaj kev tiv thaiv pwm.
Lotion
Lub luag hauj lwm ntawm emulsion yog los npog cov xim thiab muab tub lim tom qab tsim cov yeeb yaj kiab (cov hmoov uas muaj xim muaj zog yog cov xim, thiab cov hmoov tsis muaj xim muaj peev xwm yog cov muab tub lim) los tiv thaiv cov hmoov tshem tawm. Feem ntau, styrene-acrylic thiab ntshiab acrylic emulsions yog siv rau sab nrauv phab ntsa. Styrene-acrylic yog tus nqi tsim nyog, yuav tig daj, ntshiab acrylic muaj huab cua zoo thiab tuav xim, thiab tus nqi siab dua me ntsis. Cov xim pleev xim sab nrauv sab nrauv qis feem ntau siv styrene-acrylic emulsions, thiab nruab nrab-rau-siab-kawg sab nrauv phab ntsa feem ntau siv cov ntshiab acrylic emulsions.
Cov ntsiab lus
Hauv kev tsim cov coatings, cov khoom siv ua haujlwm xws li cov tshuaj tua kab mob thiab cov thickeners kuj ntxiv.
Cov saum toj no yog qhov muaj pes tsawg leeg tsom xam cov xim raw cov ntaub ntawv. Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam, tib neeg cov kev xav tau ntawm cov txheej txheem kuj tseem hloov pauv tas li. Yuav muaj ntau qhov xav tsis thoob tos peb hauv kev lag luam xim yav tom ntej!
