Qhov sib xyaw ntawm Screen Printing Ink
Jan 25, 2023
Screen luam ntawv number case, tseem hu ua screen printing number case, feem ntau yog hais txog kev siv cov tshuaj ntsuam luam ntawv number case, thiab lwm hom number case yog tib yam nrog cov xim, resin, hnyav, additives sib tov sib xyaw. Muaj ntau ntau hom kev tshuaj ntsuam luam ntawv number case, koj tuaj yeem xaiv tus number case luam ntawv raws li cov ntaub ntawv sib txawv, uas tseem yog qhov tshwj xeeb ntawm kev tshuaj ntsuam luam ntawv txheej txheem superior rau lwm cov txheej txheem luam ntawv. Qhov ruaj khov ntawm kev tshuaj ntsuam luam ntawv feem ntau yog nyob ntawm qhov kev xaiv ntawm kev tshuaj ntsuam luam ntawv number case.
Cov khoom sib txuas
Cov khoom sib txuas yog cov khoom tseem ceeb ntawm kev tshuaj ntsuam luam ntawv number case, plays lub luag haujlwm hauv dispersing pigment, muab lub vijtsam luam ntawv number case nrog qhov tsim nyog adhesion, fluidity thiab hloov kev ua tau zoo, thiab lub luag hauj lwm ntawm pigment fixation ntawm qhov chaw luam tawm los ntawm kev tsim cov yeeb yaj kiab tom qab luam ntawv. Kev sib txuas cov khoom siv feem ntau hu ua number case oil, thiab cov cuab yeej siv phom ntau
Cov khoom sib txuas tuaj yeem ua los ntawm ntau yam khoom, xws li ntau yam ntawm cov roj zaub qhuav, feem ntau tuaj yeem siv los ua cov khoom sib txuas, cov roj ntxhia kuj tuaj yeem ua los ntawm cov khoom sib txuas, hnyav thiab dej, thiab ntau yam khoom siv hluavtaws tuaj yeem ua tau. siv los ua cov khoom sib txuas.
Kev tshuaj ntsuam luam ntawv number case rheology, viscosity, nruab nrab, acid nqi, xim, dej tsis kam thiab luam ntawv kev ua tau zoo feem ntau yog nyob ntawm cov khoom sib txuas, tib xim, siv cov khoom sib txuas sib txawv, tuaj yeem ua los ntawm ntau hom tshuaj ntsuam luam ntawv number case; Thiab tib yam khoom sib txuas, siv cov xim sib txawv. Ua los ntawm tib hom tshuaj ntsuam luam ntawv number case, vim nws tsis tuaj yeem hloov qhov kev ua tau zoo ntawm tus number case, yog li qhov zoo ntawm cov tshuaj ntsuam luam ntawv number case, ntxiv rau cov xim muaj feem xyuam, feem ntau yog nyob ntawm cov khoom sib txuas.
xim
Pigment yog insoluble nyob rau hauv dej thiab organic solvents ntawm cov xim, dub los yog dawb hmoov nrog siab dispersion, raws li nws qhov chaw thiab tshuaj muaj pes tsawg leeg, muab faib ua organic pigment thiab inorganic pigment ob pawg.
Inorganic xim
Yog cov oxide ntawm cov hlau uas tsis yog-ferrous, los yog ib co hlau insoluble hlau ntsev, inorganic pigments tau muab faib ua tej yam ntuj tso inorganic pigments thiab dag inorganic pigments, natural inorganic pigments yog mineral pigments.
Organic pigment
Cov xim muaj xim organic, kuj muab faib ua ntuj thiab hluavtaws ob pawg. Synthetic organic pigments feem ntau siv tam sim no. Muaj ntau ntau hom organic pigments nrog cov xim tiav thiab kev ua tau zoo dua li cov xim tsis muaj xim. Dye yog ib qho organic compound, nws tuaj yeem yaj hauv dej, qee zaum kuj yaj hauv cov kuab tshuaj organic, los ntawm cov dye tuaj yeem npaj cov xim tsis sib haum, hu ua lake pigment, rau kev tsim cov ntawv luam ntawv luam ntawv number case.
Cov xim siv rau hauv cov ntawv luam ntawv yuav tsum tau muaj ntau yam, tshwj xeeb tshaj yog xim, dispersion, lub teeb ceev ceev, pob tshab, thiab lwm yam., lub xim ntawm cov xim pigments yog ze rau cov xim spectrum, saturation yuav tsum loj li sai tau, lub transparency ntawm magenta, ntsuab. thiab daj pigments siv nyob rau hauv peb thawj xim silk screen luam ntawv number case yuav tsum siab, tag nrho cov pigments yuav tsum tsis tsuas yog dej resistant, tab sis kuj sai thiab tusyees ua ke nrog cov khoom sib txuas, cov roj nqus cov peev xwm ntawm cov xim yuav tsum tsis txhob loj heev, thiab cov pigment tau zoo dua muaj alkali tsis kam, acid tsis kam, cawv tsis kam thiab muaj peev xwm ua haujlwm.
Kev them nyiaj ntxiv
Kev pub mis ntxiv yog nyob rau hauv kev tsim cov tshuaj ntsuam luam ntawv number case, nrog rau kev siv luam ntawv, txhawm rau txhim kho kev ua haujlwm ntawm cov tshuaj ntsuam luam ntawv number case nws tus kheej thiab qee cov ntaub ntawv ntxiv. Raws li lub hauv paus muaj pes tsawg leeg ntawm silk screen printing number case, nyob rau hauv ib co yam ntxwv tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, lossis vim muaj kev hloov pauv, thiab tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev siv luam ntawv, yuav tsum tau ntxiv rau cov khoom siv me me. daws.
ntim
Fillers yog dawb, pob tshab, translucent los yog opaque powdery tshuaj. Feem ntau plays lub luag hauj lwm ntawm filling, sau pigment ib feem, qhov tsim nyog siv ntawm ib co fillers, tsis tsuas yog yuav txo tau cov xim noj, txo tus nqi, tab sis kuj yuav kho qhov xwm ntawm cov tshuaj ntsuam luam number case, xws li nyias tuab, fluidity, tab sis kuj. txhim kho qhov yooj ntawm cov qauv tsim. Muaj ntau yam khoom siv ntxiv, xws li: desiccant, desiccant, diluting agent, viscosifier, plasticizer thiab lwm yam.
