Hauv ob xyoos dhau los, ib hom xim ntawm cov xim ntoo xim tau dhau los ua neeg nyiam. Ntau lub npe kuj tseem tsom rau ntawv niam thiab menyuam daim ntawv, yog li lawv nyiam los ntawm niam.
Twg yog qhov zoo dua rau ntawv dawb thiab ntuj?
Qhov no tau ua rau peb tsis ntseeg txog kev siv daim ntawv tso quav dawb tau ntau xyoo.
Dab tsi yog qhov sib txawv ntawm daim ntawv dawb thiab ntawv dawb? Qhov tseeb, tsis muaj teeb meem dab tsi txawm tias cov ntaub ntawv tshaj tawm hauv cov ntawv ntuj yog nkauj ntoo ntoo sis plawv hniav, ntoo sis plawv hniav lossis xyoob fiber ntau, muaj ntau yam tshuaj lom neeg ntxiv rau muag thiab tshuaj ntxuav cov ntawv los ua cov ntawv softer thiab ntau dua resilient. Nws yooj yim dua rau ntxiv thiab tsis ntxiv cov xim ntawm tus neeg saib xyuas fluorescent thiab ntawv. Lub chaw kuaj xyuas tau ua cov kev sim thiab pom tias daim ntawv daj tso quav daj tseem muaj tus neeg sawv cev fluorescent. Yog li ntawv, daim ntaub hoob nab daj tej zaum yuav tsis zoo tshaj li daim ntawv tso zis tso quav dawb.
Ntaub hoob nab ntxiv nrog tus fluorescent agent?
Ua ntej, muaj ntau yam teeb meem nrog cov phuam so tes uas muaj cov tshuaj fluorescent.
Muaj qee lub npe loj uas muaj npe zoo uas muaj kev xav pom tias cov ntawv dawb yog cov ntawv dawb nrog ntau tus neeg sawv cev fluorescent, thiab cov tshuaj fluorescent ntau dua
Qhov tseeb, koj tsis tas yuav hnov tus sawv cev fluorescing sai li sai tau koj
Raws li cov kev cai ntawm Suav teb, cov ntaub hoob nab thiab lwm cov ntaub hoob nab yog cov ntaub ntawv tso quav dawb uas tso cai tsim nyog ntxiv cov khoom siv rov qab thiab cov tshuaj fluorescent ntev li ntev tau kom lawv tsis dhau tus txheej txheem.
Txawm li cas los xij, lub teb chaws muaj kev cai ntau dua rau kev tsim khoom ntawm lub ntsej muag.
Napkins, phuam so tes, thiab cov ntaub so ntswg xws li ntawv tsis tuaj yeem siv nrog cov tshuaj fluorescent rau colony thiab lwm yam kev ntsuas, thiab yog nruj dua daim ntawv tso quav.
Ntxiv ntau muag ntxiv thiab ntub zog tus neeg sawv cev rau daim ntawv ntuj
Cov ntsiab lus tsis tau pulp muaj cov lignin ntau dua cov ntsiab lus
Daim ntawv tsim tawm yuav nyuaj heev, yog li ntawv ntuj yuav ntxiv ntau muag thiab ntub lub zog tus neeg sawv cev dua li daim ntawv dawb.
Xie Yimin, Tus Thawj Fwm ntawm Tsev Kawm Ntawv Pulp thiab Ntawv Engineering, Hubei University of Technology, tau hais
Feem ntau, cov ntsiab lus ntawm cov tshuaj lom hauv cov ntawv tsis muaj lub ntsej muag tseem tseem me me, yog li txhua tus xav tias daim ntawv ntuj muaj ntau dua ib puag ncig.
Tus kws kho mob nqaij pojniam tswv yim
Qee daim ntawv dawb tau muaj ntxhib ntxhib, thiab txhais tes ua nyuaj. Cov tawv nqaij ntawm tus me nyuam yog qhov muag heev thiab muag heev. Yog tias koj siv cov ntawv xim txhawm rau so lub zog pom, nws yuav ua rau tsis xis nyob. Yog li ntawd, nws yuav tsum tsis txhob xaiv qhov muag dig muag. Nws zoo nkaus li tias tsuas yog daim ntawv ua tau raws cov qauv yog daim ntawv zoo.
