Cov kev xav tau rau dyes thiab xim inks hauv kev hloov luam ntawv
Rau disperse dyes siv nyob rau hauvhloov luam ntawv,Qhov kub sublimation yuav tsum qis dua qhov melting point ntawm fiber ntau macromolecules thiab tsis ua rau lub zog ntawm cov ntaub. Qhov tsim nyog ua haujlwm kub rau polyester yog 180-210 degree . Nyob rau hauv qhov kub thiab txias, sublimation ntawm dyes muaj ib tug molecular hnyav ntawm 230 thiab 270. Feem ntau muaj peb hom disperse dyes nrog molecular luj nyob rau hauv no ntau yam.
Fast-dyeing disperses dyes: qhov kub tuaj yeem sublimated ntawm li 180 degree C, thiab xim yuav hloov thaum kub nce, thiab cov npoo yuav nkag mus.
Zoo disperse dyes: qhov kub thiab txias yuav sublimated mus rau qhov ntau ntawm 180-210 degree . Cov plaub hau xim nkhaus yog tiaj. Qhov kub tsis tshua muaj qhov cuam tshuam rau dyeing, thiab nws yog qhov tsim nyog disperse dye rau kev hloov luam ntawv.
Guangzhou Jiangchuan Printing Equipment Co., Ltd. tshwj xeeb hauv kev tsim cov menyuam hloov tshuab luam ntawv, tshuab luam ntawv kub hloov tshuab, tshuab luam ntawv kub, tshuab luam ntawv tiaj tus, tshuab luam ntawv sublimation, thiab ribbon hloov tshuab luam ntawv.
Ncua dyeing disperses dyes: dyes tsis tuaj yeem ua tau zoo thiab tsim xim ntawm 180-210 degree . Yog tias qhov kub thiab txias tau nce, cov xim zoo tuaj yeem tau txais. Xws li dyes yog kub-nyob ntawm seb thaum dyed.
Raws li cov xwm txheej saum toj no, cov dyes haum rauhloov luam ntawvyuav tsum ua raws li cov cai hauv qab no:
(1) Cov dyes rau kev hloov luam ntawv yuav tsum tau ua kom tag nrho sublimated thiab tsau ntawm cov fibers hauv qab 210 degree, thiab zoo ntxuav ceev ceev thiab ironing ceev yuav tau.
(2) Cov dyes ntawm kev hloov luam ntawv tuaj yeem ua tiav sublimated thiab hloov mus rau hauv cov pa roj-theem dye macromolecules tom qab tau rhuab, condensed rau saum npoo ntawm cov ntaub, thiab tuaj yeem diffuse rau hauv fiber ntau.
(3) Cov xim siv rau kev hloov luam ntawv muaj qhov sib txuam me me rau cov ntawv hloov pauv thiab qhov loj affinity rau cov ntaub.
(4) Cov dyes rau kev hloov luam ntawv yuav tsum muaj xim ci thiab ci.
Xim number case rauhloov ntawv luam ntawv
Rau kev luam ntawv ntawm cov ntawv hloov pauv hloov pauv, feem ntau ntawm lawv siv tshuab luam ntawv thiab cov khoom siv tshuaj ntsuam luam ntawv. Cov xim muaj pes tsawg leeg yog tsim los ntawm dyeing, tsheb, nplaum thiab lwm yam. Kev npaj ntawm cov xim number case yog sib tov cov saum toj no peb yam thiab ces ncuav nws mus rau hauv ib tug colloid zeb los yog ib tug peb-yob zeb rau kev sib tsoo, kom cov xim yog sib npaug zos rau cov xim number case.
(1) Coloring agent
Lub luag haujlwm ntawm lub tsheb yog kom sib npaug faib cov xim hauv cov xim xim thiab hloov cov xim ntawm cov khoom siv luam ntawv mus rau cov ntawv hloov. Lub tsheb yuav tsum pheej yig, tsis muaj tshuaj lom thiab tsis muaj hluav taws xob. Raws li qhov xav tau no, dej yog qhov tsim nyog tshaj plaws. Txawm li cas los xij, cov ntawv hloov pauv yog ua los ntawm cellulose .. Thaum cov dej siv los ua lub tsheb, cov fibers yuav nthuav dav, ua rau lub deformation ntawm cov qauv zoo, thiab nws yog ib qho nyuaj rau tsim nyob rau hauv kev kub ceev vim lub evaporation qeeb ntawm cov dej. Yog tias siv lub tsheb organic hnyav, txawm hais tias qhov deformation ntawm daim ntawv me me, cov xim number case tuaj yeem luam cov qauv zoo thiab muaj qhov tsim nyog volatility, uas yog qhov zoo rau qhov zoo ntawm kev kub ceev ntau lawm. Txawm li cas los xij, nws muaj qhov tsis zoo ntawm tus nqi siab thiab yooj yim combustion. Ceev faj nrog nws .. roj tsheb xws li cov roj kub kub kub kuj siv tau. Tab sis cov roj kub kub tuaj yeem ua rau cov dye sib sib zog nqus mus rau hauv cov ntawv hloov pauv, cuam tshuam rau cov xim ntawm cov ntawv hloov pauv mus rau cov ntaub.
(2) Binder
Binder yog hais txog cov khoom uas tswj cov adhesion ntawm xim number case. Yog hais tias tus nqi ntawm cov ntaub ntawv me me dhau lawm, lub viscosity ntawm tus number case tsis tuaj yeem lav, ua rau cov ntawv luam tawm tsis zoo ntawm cov ntawv hloov pauv. Yog hais tias tus nqi ntawm cov binder loj dhau lawm, qhov hloov ceev ntawm cov zas xim los ntawm cov ntawv hloov mus rau cov ntaub yuav qeeb, uas yuav ua rau cov khoom seem hauv cov ntawv hloov pauv. Cov xim ntau dhau ntawm daim ntawv. Nyob ntawm lub tsheb siv, lub binder yuav tsum tau xaiv nyias. Thaum cov dej siv los ua lub tsheb, feem ntau siv hluavtaws zaj pos hniav los yog carboxymethyl cellulose yog siv los ua cov ntaub ntawv: thaum siv cov kuab tshuaj organic lossis roj ua lub tsheb, ethyl cellulose tuaj yeem siv los ua cov ntawv khi.
