WaterBase Cov kua roj vanish / WaterBase txheej yog xa mus rau cov kua roj aqueous lossis cov roj dej rau cov tshuaj pleev lossis cov xim pleev rau sab nrauv (SpotCoating). Hauv kev luam ntawv, nws tiv thaiv prints thiab txhim kho ci. Qhov zoo yog tsis muaj tshuaj lom, tsis muaj kuab paug ib puag ncig, tsis muaj kuab lom (tsis muaj tsw), tuaj yeem txhim kho thaj chaw ntau lawm, yog qhov zoo rau kev noj qab haus huv ntawm cov neeg ua haujlwm; thiab tuaj yeem ua tau raws li cov khoom lag luam ib puag ncig ntawm Tebchaws Europe thiab Tebchaws Asmeskas. Cov kua pleev xim rau cov dej tau nrawm, muaj kev tiv thaiv zoo, tsis yooj yim tig daj, thiab muaj lub ci siab. Nws yog siv dav hauv ntau hom ntawv. Cov ntaub ntawv tshwj xeeb hauv cov kua roj voos tuaj yeem siv hauv cov khoom siv uas tsis yog nqus dej xws li kub, nyiaj, PET, PP, PVC, thiab lwm yam.
Dej varnishes feem ntau muaj 80-90% aqueous resin thiab 10-20% lwm yam ntxiv. Tom qab txheej nrog glazing, txheej txheej polymer nyias nyob sab saum npoo ntawm cov txheej, muab cov txheej txheej sib txawv vim cov qauv sib txawv ua ke. Xws li lub teeb ci, matte, abrasion thiab lwm yam.
Dej ntxuav ntoo yog qhov tseem ceeb tshaj plaws ntawm cov kua roj vanish. Nws txiav txim siab thiab cuam tshuam rau cov yam ntxwv ntawm cov kua roj vanish, xws li gloss, adhesion, abrasion tsis kam, dryness, thiab lwm yam, yog li cov kev xaiv tsim nyog ntawm cov dej-xim cob yog qhov tseem ceeb rau kev ua tiav ntawm cov kua roj vanish.
Muaj ntau yam ntawm cov resins, xws li dej-based rosin-hloov txiv neej acid acid cob, dej raws urethane cob, dej raws acrylic cob, dej raws li alkyd cob, thiab dej raws li amino cob. Rau cov kua roj vanish, xaiv cov khoom siv yuav tsum muaj cov yam ntxwv ntawm kev yooj yim kom yaj ntsev, zoo tso dej tawm, zoo gloss tom qab tsim zaj duab xis, tshav kub ua hauj, zoo tshuaj ua hauj, ceev ceev kom nrawm, thiab lwm yam, thiab dej-raws acrylic copolymer cob. Cov. Nws tuaj yeem ua tau raws li cov tseev kom muaj ntawm kev luam ntawv lo iav qis kawg nkaus. Yog li no, thaum tsim cov kua pleev cov dej-cov kua pleev, cov ntawv luam tawv tawv ntawm cov dej-raws acrylic yog peb qhov kev xaiv zoo tshaj plaws.
Cov dej ntshiab aqueous acrylic copolymer resin tuaj yeem muab faib ua cov kua dej kua roj aqueous acrylic, cov dej uas muaj kua qaub zoo nkauj, thiab cov kua pleev xim acrylic. Acrylic emulsions tau muab faib ua cov yeeb yaj kiab-tsim cov acrylic emulsions thiab tsis muaj zaj duab xis-ua acrylic emulsions. Cov khoom ntawm aqueous acrylic copolymer cob yog tsim ntawm monomers. Kev ua tau zoo thiab qhov cuam tshuam ntawm cov txheej txheem hluavtaws sib txawv. Qee tus monomers tuaj yeem txhim kho gloss thiab hardness, thaum lwm tus muab tshuaj lom neeg ua haujlwm thiab kev nplaum. Coob tus ntawm cov kev sim tau ua pov thawj tias kev xaiv ntawm aqueous kua qaub kua qaub thiab kua qaub emulsion zoo tagnrho rau kev ua tiav ntawm cov kua roj vanish uas yog kev sib xyaw.
Lwm qhov ntxiv kuj tseem yog lub luag haujlwm tseem ceeb hauv kev txhim kho thiab txhim kho kev ua haujlwm ntawm cov kua roj vanish. Xws li cov tshuaj tiv thaiv qib, cov neeg sawv cev ntub dej, cov neeg ua rau cov neeg ua haujlwm, tiv thaiv cov neeg ua haujlwm. Tus neeg sawv cev leveling txhim kho qhov fluidity, ntev ntev ntawm lub sij hawm qib, thiab pab cov xim ua cov xim tiaj tiaj zaj duab xis tom qab ziab kom tsis txhob muaj dej ntws thiab txhaws. Tus neeg sawv cev ntub dej tsuas yog txo qhov nro ntawm qhov cov kua roj vanish txheej txheem thiab txhim kho qhov muaj peev xwm ntub dej ntawm txheej rau ntawm qhov chaw ntawm cov txheej. Lub defoamer tsuas yog inhibits thiab tshem tawm cov foaming ntawm cov kua roj vanish nyob rau hauv cov kev ncig, tsis txhob muaj ntau cov npuas dej tsis haum rau kev ua haujlwm. Cov neeg sawv cev tiv thaiv tuaj yeem txhim kho qhov kev tiv thaiv kev sib txhuam, khawb tsis kam thiab ua haujlwm zoo ntawm cov kua pleev cov dej. Tsis tas li ntawd, ib qho me me ntawm kev pabcuam kev tiv thaiv yog tsim nyog ntxiv rau kev tsim qauv, kom cov khoom ntawm cov kua roj aqueous tuaj yeem sib txuam nrog ntau dua, lub zog cohesive ntawm lub system qis qis, thiab lub ntsej muag hloov kho tau zoo dua.
Cov kua roj vanish yog tsim rau tshwj xeeb kev sib txuas kab teeb pom kev zoo chav tsev, off-line yob txheej txheej glazing tshuab, flexographic glazing, gravure glazing, thiab lwm yam, thiab daim ntawv thov tseem ceeb dua txuas teeb (xws li KBA KBA104, KBA105), offline cov menyuam yog coated nrog lub teeb. Tshwj xeeb, kev sib txuas ntawm lub teeb, ntxiv rau qhov tsawg dua thiab tsis muaj hmoov av, kuj tseem tuaj yeem txhim kho cov ntawv luam ntawv tsawg dua (txo qis dua), txo lub sijhawm tos kom tiav tom qab ua tiav. Tom qab lub teeb tau luam tawm ntawm kab, txoj kev tuag-txiav thiab lwm yam kev ua tom qab tuaj yeem ua tiav tom qab 2 txog 6 teev.
Txawm li cas los xij, tsis muaj txoj kev twg uas koj xaiv ci dhau los, yog tias koj xav ua tiav qhov zoo txaus siab ntawm cov nyhuv glazing. Yuav tsum txawj siv cov kua roj vanish. Yog li, hauv kev siv cov kua roj pleev cov dej, peb pom zoo kom paub zoo txog peb yam hauv qab no:
1) Tus nqi txheej: Tom qab cov nqi ntawm cov xim zaj duab xis tsim, qhov ci tau zoo thiab qhov ua puas yog siab dua. Yog tias cov txheej pleev xim me me, cov kua roj vanish tsis tuaj yeem ua tiav cov yeeb yaj kiab uas tsis tu ncua, ua rau tsis muaj qhov tsis zoo thiab tsis ua rau muaj kev tiv thaiv thiab tsis zoo nkauj. Txawm li cas los xij, yog tias txheej txheej qhov ntau yog loj, txheej txheej ntawm cov yeeb yaj kiab yog tuab, uas ua rau cov nqi ntawm qhov ci me me, thiab tseem cuam tshuam rau qhov ua kom qhuav, thiab muaj kev cuam tshuam loj yuav tshwm sim. Peb feem ntau pom zoo tias txheej ntub yuav tsum yog 4 rau 10 g / m2, thiab cov txheej txheem tshwj xeeb yuav tsum tau sib txawv raws li cov ntawv thiab cov cuab yeej.
2) Viscosity: Cov viscosity ntawm cov menyuam sab saum toj feem ntau pom zoo kom yog 18 txog 25 vib nas this (DIN 4, 25 ° C). Lub viscosity ntawm xaim (xws li Roland 705) feem ntau pom zoo kom 40 txog 70 vib nas this (DIN 4, 25 ° C). Lub viscosity tsawg dhau, thiab qhov ua haujlwm ntawm kev tiv thaiv thiab kho kom zoo nkauj tsis tau; yog tias viscosity siab, tej zaum yuav muaj qhov tshwm sim tias kev tiaj tiaj tsis zoo thiab qhov ua kom qhuav tau qeeb. Cov kua roj voos thiab cov kua hauv cov dej feem ntau yog dej, thiab kev sib xyaw ua ke ntawm isopropyl cawv: dej 1: 1 tuaj yeem siv ua kua zom raws li cov kev mob tshwj xeeb. Lub viscosity tshwj xeeb yuav tsum tau kho raws li cov ntawv thiab cov cuab yeej.
3) Kom qhuav kub thiab sijhawm: cov kua roj aqueous feem ntau tso siab rau permeation kom qhuav thiab hla kev sib txuas kom tua tau. Cov khoom siv ziab khaub ncaws ua tau zoo dua yog cov cua kub kom qhuav thiab infrared kom qhuav. Feem ntau, infrared qhuav yog qhov zoo tshaj plaws. Txij li thaum lub ntsiab hnyav ntawm cov kua roj pleev cov kua roj yog dej, thiab cov cua sov ntawm cov dej ntawm cov dej yog qhov sib txuam siab, qhov ua kom qhuav yog qeeb dua li cov roj. Los ntawm tib lub token, nws yog qhov siab dua hauv kev ziab qhov kub dua li cov kua roj pleev. Feem ntau pom zoo ntawm 80 ~ 100 ° C, lub qhov nqus kom qhuav yog li 2m. Yog tias qhov kub tsis txaus, lub ziab khaub ncaws kom qhuav dhau, lub txheej txheej yuav tsis qhuav, thiab cov nplaum rov qab thiab so yuav tshwm sim tiag, tab sis yog tias qhov kub siab dhau, lub sijhawm ziab kom ntev, cov ntawv fiber los poob. dej ntau dhau, daim ntawv ua nkig, thiab nws yooj yim yuav tawg thiab tawg tuaj yeem tshwm sim thaum lub sijhawm ua.
Qhov saum toj no tsuas yog piav qhia luv luv ntawm peb qhov teeb meem tseem ceeb thaum siv cov kua roj vanish, tab sis kev siv cov kua roj vanish tseem ua raws cov txheej txheem luam ntawv sib txawv, cov khoom siv luam ntawv, ntawv hom, cov cwj mem kua thiab cov khoom siv coj los ua kom dej - raws cov kua roj vanish Qhov zoo tshaj plaws ntawm qhov ua tau zoo.
Cov kua roj vanish tau hloov maj mam hloov cov roj av-cov kua roj vanish thiab cov roj pleev cov roj vim nws qhov zoo ntawm kev tiv thaiv ib puag ncig thiab kev siv yooj yim. Nyob rau hauv lub neej yav tom ntej, nws yuav saws los ntawm ntau thiab ntau dua cov tshuab luam ntawv.
