Peb muaj keeb kwm ntawm xyoob los ntawm Xyoob Papermaking hauv Suav. Xyoobo fiber morphology thiab tshuaj muaj pes tsawg leeg yog tshwj xeeb. Qhov nruab nrab fiber ntau yog ntev, thiab lub teeb fiber ntau microstructure tshwj xeeb yog tshwj xeeb. Lub zog kev txhim kho kev ua tau zoo thaum lub sij hawm los sis yog qhov zoo, muab cov tshuaj dawb, muab cov tshuaj dawb rau cov khoom lag luam ntawm cov roj ntsha siab thiab lub teeb ci ci. Cov ntsiab lus ntawm xyoob ntawm xyoob raw cov ntaub ntawv (li 23% -32%) yog qhov siab, uas yog qhov ntau 20% -25%), uas yog ze rau cov ntoo conferous Cov. Lub siab hemicellulose thiab silicon cov ntsiab lus ntawm cov khoom siv raw kuj coj qee yam kev nyuaj siab ntawm lub sam thiaj li kev ntxuav tes thiab cov cawv dub thiab cov cuab yeej siv dub. Dua li ntawm qhov no, xyoob raw cov ntaub ntawv tseem yog cov khoom siv raw zoo rau papermaking.

Cov tshuaj dawb ntawm cov khoom loj thiab nruab nrab ntawm cov nroj tsuag pulping ntawm xyoob yuav cia li txais yuav TCF lossis ECF cov txheej txheem tshuaj dawb. Feem ntau hais lus, ua ke nrog kev sib sib zog nqus thiab oxygen delignification ntawm pulping, TCF lossis ECF cov tshuaj ntxuav tshuaj dawb yog siv. Nyob ntawm tus naj npawb ntawm cov tshuaj tov tshuaj, xyoob sis xyoob tuaj yeem ua kom dawb rau 88% -90% ci ci.

Peb cov xyoob xyoob tawv nqaij yog txhua tus tshuaj noj mov noj dawb rau ECF (Anchagal Currorine pub dawb), feem ntau muaj ntau dua li 800ml / g. ECF cov ntaub so ntswg ua kom huv si muaj cov pulp zoo dua, siv cov tshuaj tsawg dua, thiab muaj cov tshuaj ua kom huv. Nyob rau tib lub sijhawm, cov cuab yeej siv tau paub tab thiab kev ua haujlwm yog ruaj khov.

Cov txheej txheem cov txheej txheem ntawm ECF keeb kwm ntaub so ntswg-dawb, oxygatation dedigication, thiab tom qab ntawd DRECATION-tu-ntxuav-ntxuav-ntxuav-ntxuav-ntxuav yog nqa tawm Hauv kev ua ntu zus tom qab ntxuav. Cov tshuaj tsw qab yog muab tshuaj pleev kom huv yog qhov tseeb. Qhov dawb huv ntawm cov xyoob xyoob ntoo pulp nqaij tuaj yeem ncav cuag ntau dua 80%.
