Coated paper yog ib hom ntawm cov ntaub ntawv luam tawm uas feem ntau siv rau luam tawm cov xim luam yeeb, cov ntawv ci ci, cov ntawv tshaj tawm lossis cov ntawv ntim khoom. Lub ntsiab tseem ceeb tshwj xeeb ntawm cov ntawv zoo li yog nws thaj chaw du.
Coated ntawv ntau lawm
Coated ntawv yog tsim los ntawm cov khoom siv tib yam li cov ntawv txhuas. Raws li txoj cai, txoj kev no muaj peb ntu. Ua ntej, cellulose thiab dej yog sib xyaw rau hauv lub thawv cais hauv qee qhov sib txawv, tom qab ntawd qhov sib tov yog nchuav mus rau qhov tshwj xeeb tig webs, qhov twg los ntawm nias nws hloov mus rau hauv cov ntawv.
Rau kev tsim cov ntawv coated, ib txoj kev daws teeb meem uas siv kua nplaum. Cov tshuaj no tau ntxiv rau thaum pib theem ntawm kev npaj ntawm qhov sib tov los yog twb tau dhau los ua ntawv ci tau glued nrog nws. Cov khaubncaws sab nraud povtseg ntau dua ntawm sizing yog thov rau saum npoo ntawv, qhov smoother nws dhau los.
Calendering cov ntawv coated yog qib kawg, hauv cov ntawv uas tau ua tiav yog siv cov yob loj loj. Ua raws li hom, qhov saum npoo ntawm daim ntawv siv ntawm lub matte, semi-matte lossis gloss effect. Ib daim ntawv sib cais ntawm cov ntawv lo yog cov duab los nrog coated. Cov khoom siv no feem ntau siv rau kev tsim cov ntawv npog lossis cov ntawv luam tawm zoo. Kev siv ntau tshaj plaws rau cov xim coated board yog nyob rau hauv kev luam ntawv duab.
Hauv qhov loj me, cov ntawv coated tuaj yeem yog ntawv lossis yob. Hauv daim ntawv ntawm yob, cov khoom siv feem ntau xa mus rau cov tshaj tawm lossis ntawv mills. Cov ntawv thawb ntawv yog ntim rau hauv kev ntim khoom tshwj xeeb thiab tsuas yog siv hauv kev xa ntawv luam tawm xwb.
Lub ntsiab hom ntawm cov ntawv lo
Coated paper yog tsim nyob hauv ntau hom. Raws li daim ntawv tuab tuab, nws muab faib ua peb hom - lub teeb, nruab nrab thiab siab ntsuas. Hauv thawj kis, cov nplooj ntawv tau muab lo nrog ib cov kua nplaum tov ib zaug xwb, hauv ob - ob zaug, hauv peb - peb zaug.
Kev pleev xim tuaj yeem ua rau ntawm ib lossis ob tog ntawm daim ntawv. Ob txheej txheej txheej txheej txheej txheej yog cov txheej txheem kim, yog li cov khoom siv no tsuas yog siv rau kev tsim cov khoom zoo tshaj plaws thiab kim tshaj plaws luam tawm cov teeb meem.
Cov khoom yooj yim ntawm cov ntawv coated
Lub ntsiab zoo ntawm cov ntawv coated yog opacity, nce lub zog, zoo thiab muaj peev xwm tiv taus ya raws. Them nyiaj tshwj xeeb rau qhov tseeb tias cov khoom siv no tsis muaj txiaj ntsig zoo rau kev luam ntawv tom tsev. Coated ntawv nqus tau ob peb zaug ntxiv dua number case thiab tsuas yog siv rau kev thev naus laus zis nkaus xwb. Kev siv cov tshuab luam ntawv yooj yim tuaj yeem ua rau cov duab kos thiab cov ntawv luam.
