Ob chav sided panels yog ua los ntawm qhov loj me thiab qhov loj me.Nws cov qauv feem ntau yog muab faib ua cov txheej hauv qab, txheej txheej txheej, txheej txheej, txheej txheej thiab txheej txheej.Hauv qab ntawm daim ntawv whiteboard yog grey xim.Nws yog tsim nrog deinking ntawm cov ntawv xov xwm pov tseg, yog li cov khoom xyaw hauv qab txheej yog sib xyaw heev;Qhov saum npoo yog dawb, nyias txheej txheej sib xyaw nrog cov khoom siv tshuaj lom neeg xws li kaolin hmoov, binders, thiab lwm yam. Cov txheej txheej saum npoo (coated nto) muaj siab dawb, zoo number case absorption, zoo flatness, zoo printing gloss, zoo rigidity thiab zoo folding. tsis kam ntawm cardboard nws tus kheej.Tom qab qhov saum npoo ntawm daim ntawv ob sab tau coated, cov khoom nto tau zoo heev.Nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov xim zoo nkauj, thiab tuaj yeem siv los ua cov khoom zoo rau cov khoom ntim khoom nruab nrab thiab qib siab.
Foling boxboard yog ib lub thicker, muaj zog, dawb cardboard.Nws yog tsim los ntawm 100% bleached kraft ntoo pulp uas yog dawb-beating.Nws yog tsim los ntawm kev ntxiv cov fillers dawb xws li talcum hmoov thiab barium sulfate ntawm Foursdrinier daim ntawv tshuab, thiab ces calendering los yog embossing.
Tseem muaj qhov sib txawv ntawm ob sab thiab FBB hauv dej nqus thiab roughness.FBB muaj qhov nqus tau siab thiab qis roughness.Kev nqus dej ntau dua tuaj yeem ua rau cov dot nce tau yooj yim dua, thaum qis roughness ua rau tsawg deformation ntawm daim ntawv nyob rau hauv kev luam ntawv siab thiab ib tug thinner number case zaj duab xis, uas yuav pab txo tau cov dot nce.Yog li ntawd, lub rooj tsavxwm ob tog tsis zoo li FBB hais txog kev tsim tawm suab.
Daim ntawv smoothness, gloss thiab nqus dej kuj tseem ceeb heev.FBB muaj qhov ua tau zoo heev.Thaum tus number case luam tawm rau ntawm daim ntawv, cov capillary hauv txheej absorbs tusyees, uas lav qhov kev hloov pauv siab txawm tias me me ntawm number case.Nws yog qhov yooj yim ruaj khov thiab tuaj yeem tsim cov duab zoo li qub thiab qhuav.Cov ntawv luam tawm yog glossy, muaj yeeb yuj thiab txheej txheej.Cov ntawv muaj cov smoothness siab, muaj zog specular reflection thiab zoo gloss.Thaum lub teeb dhau los ntawm txheej number case thiab hits daim ntawv, feem ntau ntawm lub teeb yuav rov nkag mus rau hauv tus number case txheej nyob rau hauv daim ntawv ntawm specular reflection thiab nkag mus rau tus neeg saib qhov chaw ntawm lub zeem muag.Qhov muag.Tsuas yog ib feem ntawm lub teeb no tuaj yeem cuam tshuam cov xim ntawm tus cwj mem.Ntawm qhov tod tes, qhov porosity saum npoo ntawm lub rooj tsavxwm ob sab yog qhov loj, qhov chaw tsis sib xws, tus lej ntawm tus lej me me, daim ntawv tsis tuaj yeem hu rau tus number case luam ntawv, thiab tus nqi hloov pauv tsawg;Thaum tus number case loj, qhov hloov pauv tau siab heev, qhov nqus tau ntau dhau, thiab feem ntau ntawm cov number case Cov ntawv khi yog absorbed los ntawm daim ntawv, cov xim xim tsis muaj kev tiv thaiv zoo, tus number case tsis siv sai, thiab cov xim yog npub.
