① Sublimation Hloov Ntawv: Sublimation Hloov Ntawv yuav tsum ua raws cov txheej txheem tshwj xeeb: kev siv cua tsis muaj zog, thiab tsawg cov pa roj permeability kom paub tseeb hloov chaw. Lub hauv paus hnyav ntawm cov ntawv hloov pauv ntau npaum li ntawm 50 txog 70 g / m². Cov ntaub ntawv polymer xws li cov hmoov txhuv nplej siab, cov pos hniav Arabic, thiab sodium alginate feem ntau siv.

② Qhov kev sib tsoo: tawg kev hloov pauv thiab permeability, ua tiav cov kev ua haujlwm sai sai, ua tiav cov kev ua haujlwm nrawm kom ntseeg tau tias muaj peb-xim muaj me ntsis. Feem ntau, disperse dyes nrog molecular hnyav li qub li ntawm 230 mus rau 380 thiab sublimation kub ntawm 180 thiab 240℃raug xaiv. Cov nyhuv xim nyob ntawm seb tus nqi zas, hnyav, Sublimation cov yam ntxwv, thiab cov qauv ntawm cov polymer ua xim. Kev sib txuam muaj zog ntawm cov zas nplaim thiab cov molecules fiber ntau cia cov xim kom diffuse mus rau hauv cov fiber ntau sab hauv. Qhov tsim nyog, cov lus qhia kub sublimation yuav tsum nyob hauv qab no 200 degree.

③ Binders: feem ntau siv cov resins suav nrog tsawg-viscosity ethyl cellulose thiab ethyl hydrotyl cellulose. Cov kuab tshuaj uas yog suav nrog turpentine, terpineol, high-boiling alkanes, uas muaj fiber ntau-dissolving cov neeg sawv cev, nrog rau cov additives me. Cov kev xav tau ntawm cov kev yuav tsum muaj tsawg affinity nrog dyes, yooj yim zas xim, tsim nyog ruaj khov, thiab cua sov hloov adjectability.

④ Cov Qauv Ink: Tus yuam sij rau kev tsim sublimation hloov cov qauv lus dag nyob hauv cov number cases hauv cov kav dej. Xim cov ntsiab lus sib txawv ntawm 5% thiab 18%, nyob ntawm cov kev xav tau tshwj xeeb.

Thoob ntiaj teb, sublimation hloov luam ntawv tau ntev tau tsim nyob rau hauv kev lag luam tsim khoom thiab txuas ntxiv mus ntxiv. Nyob rau hauv xyoo tsis ntev los no, ntau thaj tsam hauv Suav teb tau pib tsim cov nplai sib txawv. Tam sim no, cov qauv yeeb yaj kiab feem ntau hauv Suav teb tau luam tawm siv offset lossis gravure txoj kev siv hluav taws xob siv hluav taws xob tshuab luam ntawv. Kev txhim kho ntawm cov duab tshuaj ntsuam teb rau cov qauv qauv tseem nyob hauv. Nrog rau kev nce qib txuas ntxiv thiab nrov nrov ntawm screen tshuab luam ntawv yuav ua rau cov khoom siv hluav taws xob nce ntxiv, muab cov ntaub ntawv tso tawm ntau, xim, thiab cov ntawv thov zoo nkauj.
