Qhov huv ntawm cov pulp yog hais txog qib ntawm cov cellulose thiab qhov ntau ntawm cov khoom tsis huv hauv cov pulp. Cov pulp zoo tagnrho yuav tsum muaj cellulose ntau, thaum cov ntsiab lus ntawm hemicellulose, lignin, tshauv, cov khoom rho tawm thiab lwm yam khoom tsis yog cellulose yuav tsum tsawg li sai tau. Cov ntsiab lus cellulose ncaj qha txiav txim siab qhov huv thiab kev siv tau ntawm cov pulp, thiab yog ib qho ntawm cov cim qhia tseem ceeb rau kev ntsuas qhov zoo ntawm cov pulp. Cov yam ntxwv ntawm cov pulp purity siab:
(1) muaj zog dua, cellulose yog lub ntsiab lus tseem ceeb uas ua rau daim ntawv muaj zog, pulp purity siab txhais tau tias muaj cov cellulose ntau dua, yog li daim ntawv ua tau muaj zog dua, tiv taus folding thiab lwm yam khoom siv lub cev thiab tshuab, ua kom daim ntawv siv tau ntev dua.
(2) Kev sib txuas muaj zog dua, cov cellulose fibers ntshiab tuaj yeem tsim kom muaj kev sib txuas ze dua ntawm daim ntawv kom txhim kho kev sib txuas sab hauv, yog li daim ntawv tsis yooj yim rau delaminated lossis tawg thaum raug rau sab nraud, los txhim kho lub zog tag nrho ntawm daim ntawv.
(3) dawb dua, qhov muaj cov khoom tsis huv feem ntau cuam tshuam rau qhov dawb thiab ci ntawm daim ntawv. Cov pulp purity siab, vim yog tshem tawm feem ntau ntawm cov xim tsis huv, ua rau daim ntawv qhia qhov dawb ntuj siab dua, uas yog qhov tsim nyog dua rau kev luam ntawv, sau ntawv thiab ntim khoom, thiab lwm yam, thiab txhim kho qhov pom ntawm cov khoom.
(4) cov khoom siv hluav taws xob zoo dua, cellulose muaj cov khoom rwb thaiv tsev zoo, thaum cov khoom tsis yog cellulose hauv lub pulp, xws li lignin, yuav muaj cov khoom conductive lossis hygroscopic, cuam tshuam rau kev rwb thaiv tsev hluav taws xob ntawm daim ntawv. Yog li ntawd, daim ntawv ua los ntawm cov pulp purity siab muaj ntau yam kev siv hauv kev tsim hluav taws xob, xws li daim ntawv rwb thaiv tsev cable, daim ntawv capacitor, thiab lwm yam.
Kev npaj cov pulp purity siab, kev lag luam ntawv niaj hnub no siv ntau yam txheej txheem pulping siab heev, xws li tshuaj pulping (suav nrog sulphate pulping, sulphite pulping, thiab lwm yam), mechanical pulping (xws li thermal grinding mechanical pulp TMP) thiab chemical mechanical pulping (CMP) thiab lwm yam. Cov txheej txheem no txhim kho qhov huv ntawm pulp los ntawm kev tshem tawm lossis hloov cov khoom tsis yog cellulosic ntawm cov khoom siv raw.
Cov ntawv pulp purity siab yog siv dav hauv ntau qhov chaw xws li ntawv kab lis kev cai qib siab, ntawv ntim khoom, ntawv tshwj xeeb (piv txwv li, ntawv rwb thaiv tsev hluav taws xob, ntawv lim dej, ntawv kho mob, thiab lwm yam) thiab ntawv hauv tsev, uas ua tau raws li tus qauv siab ntawm cov ntawv zoo uas xav tau los ntawm ntau yam kev lag luam.
Daim Ntawv Yashi tsuas yog ua 100% cov xyoob ntoo nkauj xwb, ib qho ci xyoob fiber, uas yog qhov kev xaiv zoo tshaj plaws rau kev ua kom huv siab thiab cov ntawv hauv tsev zoo.
