Kev Taw Qhia: Cov txheej txheem hloov pauv thermal, ib qho txheej txheem uas siv ntau hauv kev kho qhov chaw ntawm cov khoom ntim khoom kom zoo nkauj, vim nws yooj yim luam tawm, thiab xim thiab qauv tuaj yeem hloov kho tau. Nws yog ib qho txheej txheem uas cov tswv lag luam nyiam. Cov hauv qab no yog kho los ntawmRB PACKAGE.Cia peb qhia qee qhov teeb meem zoo thiab kev daws teeb meem nrog rau cov yam ntxwv cuam tshuam ntawm kev hloov pauv thermal, rau koj siv rau hauv cov khoom xa tuaj ntawm Youpin:
Kev hloov pauv cua sov
Cov txheej txheem hloov thermal yog hais txog daim ntawv hloov uas muaj cov xim lossis cov xim pleev xim ua ib qho nruab nrab, los ntawm kev cua sov, nias thiab lwm txoj hauv kev los hloov cov qauv ntawm cov kua mem ntawm qhov nruab nrab mus rau txoj kev luam ntawv. Lub hauv paus ntsiab lus ntawm kev hloov thermal yog ncaj qha mus rau qhov nruab nrab uas muaj kua mem nrog lub substrate. Los ntawm kev cua sov thiab nias ntawm lub taub hau luam ntawv thermal thiab lub tog raj kheej luam ntawv, cov kua mem ntawm qhov nruab nrab yuav yaj thiab hloov mus rau lub substrate kom tau txais cov khoom luam ntawv xav tau.
01Cov yam cuam tshuam rau kev hloov pauv thermal
1) Lub taub hau luam ntawv thermal
Lub taub hau luam ntawv thermal feem ntau yog tsim los ntawm cov txheej tiv thaiv zaj duab xis nplaum saum npoo av, cov txheej tiv thaiv zaj duab xis nplaum hauv qab thiab cov khoom cua sov. Cov khoom cua sov yog cov ntaub thaiv silk conductive. Nrog kev pab los ntawm cua sov tsim los ntawm lub zog hluav taws xob, cov khoom me me ntawm cov txheej kua mem ntawm cov duab kos tau embossed thiab yaj kom ua tiav kev hloov kua mem.
Qhov ceev ntawm kev luam ntawv ntawm kev hloov pauv thermal nyob ntawm lub sijhawm xav tau rau txhua kab ntawm cov duab thiab cov ntawv nyeem. Yog li ntawd, lub taub hau hloov pauv thermal thiab daim ntawv hloov pauv yuav tsum muaj kev hloov pauv cua sov zoo, kom cov cua sov tsim los ntawm lub tshuab cua sov tuaj yeem hla dhau cov txheej tiv thaiv, cov ntawv hloov pauv substrate thiab qhov sib txawv thiab thaum kawg mus rau qhov chaw ntawm lub substrate kom ntseeg tau tias cov kua mem muaj lub sijhawm hloov pauv txaus.
2) Kua mem
Cov khoom sib xyaw ntawm cov kua mem thermal transfer feem ntau yog peb ntu: xim (xim lossis xim zas), quav ciab thiab roj, ntawm cov quav ciab yog cov khoom tseem ceeb ntawm cov kua mem thermal transfer. Cov khoom sib xyaw ua ke ntawm cov kua mem thermal transfer dav dav tuaj yeem xa mus rau Rooj 1.
Rooj 2 yog ib qho piv txwv ntawm cov kua mem hloov cua sov rau kev luam ntawv. N-methoxymethyl polyamide yog yaj rau hauv benzyl cawv, toluene, ethanol thiab lwm yam kuab tshuaj, cov xim tiv taus cua sov thiab bentonite raug ntxiv rau kev sib tov, thiab tom qab ntawd zom rau hauv cov kua mem luam ntawv. Cov kua mem raug luam tawm rau ntawm daim ntawv nqa khoom (xws li daim ntawv hloov cua sov) siv txoj kev luam ntawv, thiab tom qab ntawd cov ntaub raug nias thiab hloov pauv los ntawm cua sov.
Thaum luam ntawv, qhov viscosity ntawm cov kua mem sib txawv muaj feem cuam tshuam ncaj qha rau qhov kub thiab txias ntawm cov kua mem, thiab qhov kub thiab txias ntawm cov kua mem yuav tsum tau tswj hwm nruj me ntsis. Kev xyaum tau ua pov thawj tias thaum qhov kub thiab txias ntawm cov kua mem yog 60 ~ 100 ℃, thaum cov kua mem yaj, qhov viscosity ntawm cov kua mem ruaj khov ntawm kwv yees li 0.6 Pa·s, uas yog qhov zoo tshaj plaws. Feem ntau hais lus, qhov ze ntawm cov kua mem mus rau lub xeev no, qhov kev ua tau zoo dua ntawm kev hloov pauv.
Xyoo tas los no, nrog kev txhim kho ntawm Shanghai Rainbow Package Technology, qhov kub cia ntawm cov khoom luam tawm tau nce ntxiv los ntawm 45 ℃ thawj mus rau 60 ℃, uas tau nthuav dav ntau yam kev siv ntawm kev hloov pauv thermal. Tsis tas li ntawd, kev siv cov xim pob tshab lossis cov xim pob tshab muab cov xim zoo rau cov xim luam tawm.
3) Hloov cov xov xwm
Cov substrates sib txawv muaj cov yam ntxwv sib txawv, yog li thaum xaiv daim ntawv hloov pauv, koj yuav tsum tau them sai sai rau cov yam ntxwv hauv qab no ntawm cov substrate.
①Kev ua tau zoo ntawm lub cev
Cov khoom siv lub cev ntawm daim ntawv hloov pauv tau qhia nyob rau hauv Rooj 3.
Cov saum toj no yog cov khoom siv lub cev ntawm peb daim ntawv thermal transfer paper. Peb yam hauv qab no tuaj yeem xav txog thaum xaiv:
Lub thickness ntawm lub substrate feem ntau yuav tsum tsis pub ntau tshaj 20 μm;
Lub substrate yuav tsum muaj qib siab ntawm kev du kom ntseeg tau tias tus nqi hloov pauv ntawm cov kua mem;
Lub substrate yuav tsum muaj zog txaus kom ntseeg tau tias nws yuav tsis raug rhuav thaum lub sijhawm ua daim ntawv hloov pauv thiab luam ntawv.
②Cov khoom siv tshuaj lom neeg
Kev nplaum zoo thiab sib npaug ntawm cov kua mem yog ob qho tseem ceeb ntawm cov khoom siv tshuaj lom neeg ntawm daim ntawv hloov pauv. Hauv kev tsim khoom, cov khoom siv tshuaj lom neeg ntawm daim ntawv hloov pauv cuam tshuam ncaj qha rau qhov zoo ntawm kev luam ntawv. Yog tias daim ntawv hloov pauv tsis tuaj yeem ua rau cov kua mem lo zoo, lossis cov kua mem tsis tau ua tiav hauv kev tsim khoom, nws yuav ua rau pov tseg kev luam ntawv. Cov txheej txheem luam ntawv zoo thiab cov ntawv luam tawm zoo yuav tsum yog raws li kev nkag siab zoo txog cov khoom siv tshuaj lom neeg ntawm daim ntawv hloov pauv.
③Kev ua haujlwm thermal zoo
Vim tias cov txheej txheem hloov pauv tau ua tiav los ntawm kev kub siab, cov khoom siv ntawm daim ntawv hloov pauv yuav tsum muaj peev xwm tiv taus qhov cuam tshuam ntawm qhov kub hloov pauv thiab khaws cov khoom tsis hloov pauv. Feem ntau hais lus, seb qhov kev ua haujlwm thermal ntawm lub substrate ntawm daim ntawv hloov pauv thermal zoo puas tuaj yeem cuam tshuam los ntawm cov hauv qab no:
Qhov qis dua qhov tiv taus cua sov ntawm cov khoom siv tiv taus cua sov, qhov nyias dua qhov tuab, qhov zoo dua qhov hloov pauv cua sov, thiab nws cov kev ua tau zoo dua thermal;
Kev du Qhov du ntawm qhov chaw substrate, qhov qis dua qhov tiv taus cua sov thiab qhov zoo dua qhov kev ua tau zoo thermal;
