Nyob rau ib lub sij hawm, daim ntawv npog npog ntawm ib lub npias ntawm npias npias tsom tsis pom zoo nyob rau hauv qhov zoo ntawm wrinkles thiab streaks nyob rau tom qab calendering. Raws li qhov yuav tsum ua kom zoo, daim ntawv yuav tsum huv si, yuav tsum tau ntxuav dawb, tsis pub dawb thiab tsis pub dawb tom qab khos nab.
Thaum kuaj calendering tsis zoo (xws li ntsuas kub, siab, ceev, lwm yam) tsis hloov, peb siv lwm cov khoom ntim cov thawv ntawv rau calender, uas ua rau tsis muaj wrinkles thiab streaks tom qab calendering. . Los ntawm kev sib piv, nws ntseeg tias vim li cas yog vim qhov sib txawv hauv qhov zoo tshaj ntawm ob hom kev xa ntawv. Qhov saum npoo ntawm ntawv los uas yuav tsim tau wrinkles thiab streaks tom qab calendering tseem txom nyem nyob rau hauv daim ntawv zoo. Txawm li cas los xij, cov khoom siv ua tiav tau tiav lawm, thiab yog hais tias nws yog khwv tom qab lub khoos phis qis yuav tsim qee cov pob txha thiab cov hlua uas tsis ua raws li qhov yuav tsum tau ua, nws yuav tsis muaj peev xwm xa tuaj raws sij hawm thiab qhov poob loj. Thiab yog tias nws tuaj yeem kho tau los ntawm kev tsim nyog kho, qhov zoo ntawm cov calendering yuav ua tau, ib qho tuaj yeem xa raws sijhawm, thiab lwm tus tuaj yeem txo nyiaj.
Ua li no, peb tau xaiv ib qho kev ntsuas zoo los daws qhov teeb meem los ntawm ntau txoj kev ua haujlwm thiab kev sim. Cov txheej txheem yog: tempering cov duab los tom qab glazing, thiab tom qab ntawd ces kub-ziab ntawm calender ua ntej, qhov kub ntawm qhov kub ci yog tib yam li qhov ntsuas kub ntawm lub calendering, thiab kub ci yuav ua tau rau hauv calender. Nyob rau hauv kev kub ceev thiab hlau siv kis ntawm calender, cov duab ntawv muab tso rau saum npoo ntawm cov hlau tawm ntawm qhov chaw tawm ntawm qhov chaw tawm, thiab daim ntawv raug coj los rau hauv qhov chaw ziab los ntawm txoj siv hlau los xa rov qab mus rau calender . Lub qhov ncauj ntawm lub qhov ncauj. Tom qab kub zoo thiab calendering raws li cov txheej txheem calendering li qub (piv txwv li, ntxiv ib lub ci thiab ib qho kub kub), lub pob txha thiab cov hlua ntawm cov khoom siv ntawm cov khoom noj zoo.
Incidentally, feem ntau, calendering kub yog feem ntau tswj ntawm 115 ° C mus txog 120 ° C, qhov siab yog tswj ntawm 150 mus rau 180 kg / m 2, thiab qhov ceev yog li 6 - 10 m / min. Ntawm chav kawm, nyob rau hauv lub lag luam tawm, nws yuav tsum tau tsim nyog tau kho thiab mastered raws li lub thickness ntawm cardboard. Nws yog tsim nyog sau cia tias cov ntaub ntawv yuav tsum calendered, yuav tsum muaj kev xaiv nyob rau hauv daim ntawv zoo, txwv tsis pub cov yuav tsum tau ua raws li kev cai yuav tsis tau.
