Thermal hloov luam ntawv thiab nws cov txheej txheem
Thermal hloov luam ntawv yog hu ua thermal hloov luam ntawv.Nws tsis yooj yim rau kev nkag siab qhov tseeb, thermal hloov luam ntawv yog qhov ua tau zoo ntawm kev hloov luam ntawv, uas yog kev hloov luam ntawv txheej txheem hauv daim ntawv ntawm thermal hloov.
Thermal hloov luam ntawv feem ntau muab faib ua kub-melt hloov luam ntawv thiab sublimation hloov luam ntawv.Kub-melt hloov luam ntawv feem ntau yog siv rau cov khoom siv paj rwb, tab sis qhov tsis zoo yog tias nws muaj huab cua permeability tsis zoo;sublimation hloov luam ntawv feem ntau yog siv rau polyester hloov luam ntawv.Qhov tsis zoo yog tias phaj ua cov nqi siab.Sublimation hloov luam ntawv tuaj yeem muab faib ua ntau hom kev luam ntawv: offset printing, gravure printing, silk screen printing, data printing.
Lub hauv paus ntsiab lus ntawm thermal hloov luam ntawv yog me ntsis zoo ib yam li txoj kev hloov luam ntawv.Hauv thermal hloov luam ntawv, cov qauv yog thawj zaug luam tawm ntawm daim ntawv nrog dispersed dyes thiab luam ntawv inks, thiab tom qab ntawd cov ntawv luam tawm (tseem hu ua daim ntawv hloov pauv) yog khaws cia rau hauv cov chaw luam ntawv textile.
Thaum cov ntaub ntawv luam tawm, mus rau hauv lub tshuab luam ntawv hloov hluav taws xob, ua rau cov ntawv hloov pauv thiab cov ntawv tsis muaj lub ntsej muag rau lub ntsej muag ua ke, thiab dhau los ntawm lub tshuab ntawm li 210 ° C (400T), ntawm qhov kub thiab txias, cov xim ntawm cov xim. daim ntawv hloov pauv yog sublimated thiab pauv.mus rau cov ntaub, ua kom tiav cov txheej txheem luam ntawv thiab tsis tas yuav ua ntxiv.Cov txheej txheem yog qhov yooj yim heev thiab tsis tas yuav muaj kev txawj ntse uas yuav tsum tau ua hauv kev tsim khoom xws li cov menyuam luam ntawv lossis rotary screen printing.
Disperse dyes tsuas yog cov dyes uas tuaj yeem ua tau sublimated, thiab hauv kev nkag siab, tsuas yog cov dyes uas tuaj yeem hloov pauv thermally, yog li cov txheej txheem no tsuas yog siv rau ntawm cov ntaub uas muaj fiber ntau uas muaj kev sib raug zoo rau cov xim xws li acetate, acrylic. Acrylic fiber, polyamide fiber (nylon) thiab polyester fiber.
Rau thermal hloov luam ntawv, ntaub tshuab luam ntawv yuav daim ntawv decal no los ntawm cov chaw tsim khoom tshwj xeeb decal daim ntawv.Hloov daim ntawv tuaj yeem luam tawm raws li qhov xav tau ntawm tus qauv tsim thiab cov neeg siv khoom (cov qauv npaj tuaj yeem siv rau kev hloov ntawv luam ntawv).Thermal hloov luam ntawv tuaj yeem siv los luam tawm cov tsoos tsho (xws li ntug kev luam ntawv, lub hnab tsho lub mis paj ntaub, thiab lwm yam).Hauv qhov no, siv cov qauv tsim tshwj xeeb.
Thermal hloov luam ntawv sawv tawm los ntawm cov txheej txheem luam ntawv ua tiav cov txheej txheem luam ntawv, yog li tshem tawm qhov xav tau ntawm cov tshuab ziab khaub ncaws hnyav thiab kim, steamers, tshuab ntxhua khaub ncaws thiab tenter thav duab.Thermal hloov luam ntawv muaj cov yam ntxwv ntawm lub teeb tsis kam, ntxuav tsis kam, muaj zog xim ceev thiab nplua nuj xim, thiab tuaj yeem siv rau luam ntawv khaub ncaws, tsev textiles (curtains, sofas, tablecloths, umbrellas, da dej curtains, nra) thiab lwm yam khoom.
Txij li cov ntawv luam tawm tuaj yeem raug tshuaj xyuas ua ntej luam ntawv, misalignment thiab lwm yam tsis xws luag raug tshem tawm.Yog li ntawd, thermal hloov luam ntawv fabrics tsis tshua muaj tshwm sim.Tsis tas li ntawd, vim thermal hloov luam ntawv belongs rau qeb ntawm kev hloov luam ntawv, nws cov txheej txheem luam ntawv kuj suav nrog plaub txoj kev: sublimation method, txoj kev ua luam dej, txoj kev melting, thiab number case txheej peeling tau ntsib.hod.
