Hloov luam ntawv yog hais txog txheej txheem luam ntawv nyob rau hauv uas dyes yog hloov mus rau ntaub los ntawm hloov daim ntawv. Raws li cov yam ntxwv ntawm sublimation ntawm qee cov khoom tawg, cov khoom tawg xim tawg xim ntawm 150 ～ ～ 230 ℃ raug xaiv, sib xyaw nrog cov slurry los ua" xim number case", thiab tom qab ntawd raws li cov qauv tsim qauv sib txawv," ; xim number case" yog luam tawm mus rau Hloov Cov Ntawv, thiab tom qab ntawd kaw cov ntawv hloov xa ntawv nrog cov qauv thiab cov ntaub. Raws li kev tswj ntawm qee qhov kub, siab thiab sijhawm, xim zas hloov los ntawm daim ntawv luam tawm mus rau ntaub, thiab nkag mus rau sab hauv ntawm cov ntaub los ntawm diffusion. Lub hom phiaj ntawm kev tha xim.
Muaj ntau txoj hauv kev rau kev hloov luam ntawv, xws li txoj kev sublimation, hom tsiv teb tsaws, cov txheej txheem melting thiab number case txheej peeling qauv. Ntawm lawv, sublimation hloov luam ntawv yog qhov paub tab tshaj plaws.
Sublimation txoj kev
Nov yog txoj kev siv ntau hom. Siv cov yam ntxwv ntawm sublimation ntawm disperse dyes, disperse dyes nrog cov molecular hnyav ntawm 250-400 thiab ib qho me me ntawm 0.2-2 microns siv ua ke nrog dej-soluble muaj tsheb (xws li sodium alginate) los yog dej cawv-cov tshuaj nqa (piv txwv, ethyl cellulose) thiab cov roj ua kua roj yog siv los ua cov inks, uas ua tiav ntawm lub tshuab luam ntawv hloov ntawm 200 ° C rau 230 ° C rau 20 txog 30 vib nas this kom hloov pauv thiab kho cov khoom tawg ua rau cov khoom cua xws li polyester.
Cov txheej txheem sublimation feem ntau dhau los ntawm peb cov txheej txheem: ua ntej cov txheej txheem hloov chaw, txhua lub dyes yog nyob rau hauv cov yeeb yaj kiab luam tawm ntawm daim ntawv, cov xim zas xim hauv cov ntawv luam tawm thiab cov huab cua sib txawv yog xoom, thiab qhov loj ntawm huab cua sib txawv nyob ntawm tus qauv ntawm cov ntaub thiab cov xov paj suav suav. Thiab hloov siab. Hauv cov txheej txheem hloov mus, thaum daim ntawv nce mus txog qhov hloov mus rau qhov kub thiab txias, lub zas xim pib ua rau ntog los yog sublime, thiab ib qho kub siab volatilization yog tsim nyob nruab nrab ntawm daim ntawv thiab cov ntawv fiber. Thaum cov ntawv luam tawm mus txog rau qhov hloov pauv hloov, lub xim adsorption pib ua rau thaj chaw fiber ntau mus txog thaum nws mus txog rau qee yam kev kub ntxhov. tus nqi. Txij li cov zas xim hloov los ntawm daim ntawv mus rau fiber ntau yog tas mus li, nws cov adsorption tus nqi yog nyob ntawm tus nqi uas cov xim sib txawv los ua lub fiber. Txhawm rau kom cov xim zas ua rau txawv txav, ib lub tshuab nqus tsev feem ntau kos rau ntawm qhov tsis tuaj sab nrauv ntawm cov khoom siv dyed kom tau txais kev qhia diffusion thiab hloov chaw ntawm lub zas xim. Tom qab cov txheej txheem hloov mus, tom qab cov khoom siv tau hloov xim, cov ntsiab lus zas xim ntawm daim ntawv poob qis, thiab ib feem ntawm cov xim zas hloov mus rau sab hauv ntawm daim ntawv. Tus nqi ntawm cov xim tsis zoo nyob ntawm lub vapor siab ntawm cov xim, qhov sib xyaw xim ntawm cov zas mus rau cov ntawv xa mus los yog hloov cov ntawv, thiab luam ntawv zaj duab xis tuab ntawm. Txoj kev sublimation feem ntau tsis xav tau kev kho ntub dej, uas tuaj yeem txuag lub zog thiab txo lub nra ntawm kev ntxuav tu.
Txoj kev ua luam dej
Zas xim nyob hauv tus number case txheej ntawm daim ntawv hloov ntaub ntawv yog xaiv raws li ntawm daim txiag. Cov ntaub yog thawj zaug rau kev kho padding nrog kev sib xyaw ntawm kev kho cov khoom siv thiab yav dhau los, thiab tom qab ntawd nyob rau hauv lub xeev ntub dej los ntawm kub-tsiv teb tsaws, kom cov zas xim pauv los ntawm kev hloov luam ntawv mus rau daim ntaub thiab tsau, thiab thaum kawg ua npuas thiab ntxuav Isotonic kho. Thaum cov zas xim tau sib zog hloov dua, ib qho kev txiav siab siab ntawm daim ntaub thiab hloov xa ntawv.
Melting txoj kev
Tus number case txheej ntawm daim ntawv hloov chaw yog raws li dyes thiab waxes. Tus number case txheej nyob rau hauv cov ntaub los ntawm melting thiab nias, yog li ntawd ib feem ntawm tus number case yog pauv mus rau lub fiber, thiab tom qab ntawd sib nug tus tom qab kev kho mob yog ua raws li cov xwm txheej ntawm lub zas xim. Thaum siv cov txheej txheem melting, lub zog siab tshaj qhov yuav tsum tau, thiab qhov hloov ntawm qhov zas nce nrog qhov nce ntawm lub siab.
Ink txheej peeling txoj kev
Siv tus number case uas tuaj yeem ua rau muaj zog adhesion mus rau lub fiber thaum raug tshav kub, tag nrho cov txheej txheem number case tuaj yeem hloov los ntawm daim ntawv xa mus rau cov ntaub nyob rau hauv lub siab me, thiab tom qab ntawd cov lus sib kho kho tau tuaj yeem ua raws li qhov xwm ntawm tus zas.
Ntxiv rau kev tsim nyog rau cov khoom siv hluavtaws fiber ntau, hloov luam ntawv kuj tseem siv tau rau kev luam tawm ntawm cov ntshiab ntuj fiber ntau thiab cov ntaub qhwv ua ke. Nws muaj cov txiaj ntsig zoo li nram no: cov txheej txheem luv ntws, cov khoom tiav tom qab luam ntawv, tsis tas yuav tsum tau ua haujlwm tom qab xws li ncu, ntxhua, thiab lwm yam; cov khoom siv yooj yim, nqis peev me, hneev me me, kev siv zog tsawg; cov qauv zoo, nplua nuj thiab meej txheej, thiab kos duab Ua kom zoo siab thiab cov duab peb sab, nws tsis zoo li cov qauv dav dav ntawm kev luam ntawv, thiab tuaj yeem luam tawm cov duab thaij duab thiab tha xim duab qauv; luam ntawv yog qaim xim, thiab cov tar nyob rau hauv lub zas xim yog sab laug rau ntawm daim ntawv hloov chaw thaum sublimation txheej txheem, uas yuav tsis ua paug ntawm daim ntaub; Tus nqi siab, cov xim ntau xim tuaj yeem luam tawm nyob rau hauv ib zaug thaum pauv hloov yam tsis tas yuav tsum muaj lub paj sib txuam; muaj zog ua kom yooj yim, cov neeg lag luam tuaj yeem luam tawm lub sijhawm luv luv tom qab xaiv cov qauv. Ntxiv nrog rau kev luam tawm cov qauv taub hau, nws kuj tseem siv tau ntawm cov khaub ncaws Hloov cov luam ntawv ntawm cov khoom tiav, xws li cov luam tawm ib nrab ntawm tus dab tshos, ntawm caj dab, thiab hnab ris ntawm lub tsho.
Hloov tshuab luam ntawv kuj muaj nws qhov tsis zoo. Piv txwv, 80% ntawm kev hloov luam ntawv yog siv rau cov ntaub npuag polyester, 10% yog siv rau cov polyester sib xyaw ua ke, thiab 10% yog siv rau cov ntaub xws li acrylic, nylon thiab acetate fibers. Npuag ntuj cov xov tseem tsis tau tsim kom muaj neeg coob. Qhov siv dav ntawm kev siv yog raug rau qee qhov kev txwv. Ntxiv rau, cov ntawv loj yuav tsum tau siv sij hawm. Ntxiv nrog rau kev xa cov ntawv, cov ntaub ntawv thaub qab tseem xav tau. Yog li, thaj chaw ntawm daim ntawv noj yog ob zaug ntawm cov ntawv luam tawm, thiab cov ntawv pov tseg cov seem tsis tseem muaj teeb meem. Ntxiv mus, qhov kev ua hauj lwm zoo ntawm kev hloov luam ntawv yog tsawg. Kev tsim tawm ntawm lub tshuab luam ntawv hloov pauv yog 3 txog 4 meters ib feeb, thiab qhov ntau dua tsuas yog tsuas yog txog 8 meters ib feeb, uas tsuas yog tsim rau cov pas dej me thiab ntau hom.
