Nyob rau hauv dyeing ntawm ntim ntawv tais, dej-raws li dyes feem ntau yog ntxiv rau hauv cov txheej txheem pulping raws li cov ntaub ntawv qub. Ib qho yog tias qhov kev hloov pauv ntawm cov ntaub so ntswg kuj ua rau kev hloov pauv ntawm cov xim xim thaum lub sijhawm ntau lawm, thiab lwm yam yog tias feem ntau cov xim dyes rhiab rau qhov kub thiab txias (thaum lub sijhawm ziab, cov xim hloov nrog qhov kub ntawm cov kab ziab, thiab qhov kub ntawm cov pwm yog 150-250℃thaum kub nias thiab cov xim yuav hloov ntawm qhov kub sib txawv). Hauv cov ntsiab lus, cov khoom uas muaj xim ntau dua yuav tsum tsis txhob dyed.
Vim li cas thiaj muaj cov kab nrib pleb me me ntawm qhov chaw ntawm cov khoom no?
Thaum cov khoom ntim ntawv tsim, cov ntaub ntawv fiber ntau yog ib txwm adsorbed txheej los ntawm txheej, thiab cov kua pulp yuav tsis ntws tawm hauv qee qhov grooves, uas yuav ua rau lub thickness ntawm daim ntawv phaj txawv ntawm tus qauv thickness hauv tus qauv tsim tom qab ziab. , Tom qab ntawd thaum lub zog sab nraud tau txais thaum lub sij hawm siab - siab shaping, sab nraud ntawm cov fiber ntau ntawm qhov tsis sib xws ntawm cov khoom sab hauv thiab sab nrauv yuav tawg, thiab nws yuav tshwm sim zoo li tawg ntawm qhov chaw. Qhov tshwm sim no yuav tsis cuam tshuam rau lub zog ntawm daim ntawv tais ntim khoom, yog li nws tau txais hauv kev lag luam.
Vim li cas kuv tsis tuaj yeem ntxiv ib lub buckle rau buckle kuv cov khoom?
Cov khoom lag luam ntawv raug kaw thiab nqis thaum lub sij hawm molding thiab shaping, thiab yuav tsum muaj lub kaum sab xis. Cov khoom ntub dej tsis tuaj yeem raug tshem tawm ntawm cov pwm thaum lub sij hawm molding, yog li cov ntawv tais tsis tuaj yeem tsim nrog txoj haujlwm inverted.
