① Sublimation Hloov Ntawv: Zoo dua sublimation Hloov Ntawv yuav tsum muaj plua plav-dawb, thiab muaj kev tswj hwm kev ua kom tau kev luam tawm. Nws yuav tsum tau tso cai tso tawm yooj yim ntawm dyes, nthuav tawm qhov siab thermal kuj, thiab muaj tsawg zas permeability kom ntseeg tau tias kev hloov pauv hloov. Qhov uas nyiam lub hauv paus hnyav li ntawm 50 txog 70 g / m². Ntuj polymer sib khi xws li cov hmoov txhuv nplej siab, cov pos hniav ntawm cov kab mob ntawm cov pos hniav, thiab cov khoom sopium ntxiv siv ntau.

② Tsis Zoo Li Cas: Muaj Kev Hloov Seeves yuav tsum ua kom pom cov khoom siv thiab cov permeability, kev ua tiav qib yuav tsum muaj kev nrawm. Lawv yuav tsum ua kom pom zoo zoo hauv kev ua haujlwm kom ua tiav cov ntaub ntawv ua kom muaj xim sib xyaw ua ke. Dyes nrog hnyav hnyav nruab nrab ntawm 230 thiab 380 thiab sublimation kub muaj txij li 180 txog 240℃yog xaiv. Cov nyhuv xim nyob ntawm seb tus cwj pwm zas, hnyav, sublimation cwj pwm, thiab cov qauv ntawm lub hom phiaj polymer. Kev sib txuam muaj zog ntawm zas vapor thiab cov molecules fiber ntau pab tau sib sib zog nqus. Ib sublimation kub hauv qab no 200℃feem ntau nyiam dua.

③ binder: siv cov resins suav nrog tsawg-viscosity ethyl cellulose thiab ethyl hydrotyl cellulose. Cov kuab tshuaj uas yog suav nrog turpentine, terpineol, high-boiling alkanols, arylalkanes, thiab solubilizers. Cov ntxiv kuj tseem tuaj yeem suav nrog. Cov kev yuav tsum tau muaj xws li tsis muaj ib qho tseem ceeb rau dyes, yooj yim ntawm cov xim tso tawm, haum luam tawm kom ruaj khov, thiab hloov kho mus ntev, thiab kev yoog raws li kev mob kub.

④ Ink Tsim: Daim qauv tsim ntawm tshuaj ntsuam-luam tawm sublimation hloov inks yog qhov tseem ceeb heev. Zas xim cov ntsiab lus sib txawv ntawm 5% thiab 18%, nyob ntawm cov kev xav tau ntawm daim ntawv thov kev xav tau.

Thoob ntiaj teb, sublimation hloov cov ntawv luam tawm tau pom dav hauv kev lag luam teeb tsa thiab txuas ntxiv nthuav dav. Nyob rau hauv xyoo tsis ntev los no, kev tsim khoom hauv tsev kuj tau nce mus thoob plaws ntau thaj chaw hauv Suav teb. Tam sim no, cov ntawv luam tawm tshaj plaws yog tsim tawm siv offset lossis graver tshuab luam ntawv, nrog tsuas yog siv me me siv flatbed screen luam tawm. Kev xa tawm teb rau sublimation hloov tseem nyob hauv kev txhim kho. Nrog rau kev nce qib txuas ntxiv hauv Vijtsam Tshuab Luam Ntawv, kev siv dej-ua haujlwm lossis emulsion cov kev lag luam kom muaj ntau yam los ntawm kev luam ntawv, xim, thiab cov ntawv thov zoo nkauj.
