Pulp Quality Evaluation

Qhov zoo ntawm pulp yog txiav txim siab los ntawm nws cov fiber ntau morphology thiab fiber ntau purity.Cov khoom ntawm ob yam no feem ntau yog txiav txim siab los ntawm ntau yam ntawm cov khoom siv raw siv, nrog rau txoj kev tsim khoom thiab kev ua kom tob.
Nyob rau hauv cov nqe lus ntawm fiber ntau morphology, lub ntsiab yam tseem ceeb yog qhov nruab nrab ntev ntawm fibers, qhov ratio ntawm fiber cell phab ntsa thickness rau cell lumen txoj kab uas hla, thiab cov ntsiab lus ntawm non-fibrous hybrid hlwb thiab fiber bundles nyob rau hauv lub pulp.Feem ntau, qhov nruab nrab fiber ntau ntev yog qhov loj, qhov sib piv ntawm cov phab ntsa thickness ntawm lub xov tooj ntawm tes yog me me, thiab cov pulp uas tsis muaj los yog ob peb cov tsis muaj fiber ntau hybrid hlwb thiab cov pob fiber ntau muaj lub zog zoo, lub cev qhuav dej thiab cov ntaub ntawv, thiab tuaj yeem tsim muaj zog. ntawv.Cov ntaub ntawv qib siab, xws li spruce softwood pulp, paj rwb thiab linen pulp, thiab lwm yam.
Nyob rau hauv cov nqe lus ntawm fiber ntau purity, pulp nrog siab cellulose cov ntsiab lus thiab cov ntsiab lus tsawg ntawm lwm yam feem ntau zoo dua.Hom pulp no muaj lub zog ruaj khov, muaj zog ruaj khov, siab dawb thiab zoo hluav taws xob rwb thaiv tsev thiab lwm yam khoom zoo heev.

Kev siv sib txawv thiab qib ntawm cov ntawv muaj cov kev xav tau sib txawv rau cov ntaub ntawv zoo.Nws tsis yog tsim nyog los xaiv cov pulp nrog qhov zoo tshaj plaws fiber ntau zoo thiab siab tshaj plaws fiber ntau purity.Thiab pheej yig tshaj ntau yam.Kev lag luam thiab hauv kev tsim khoom, ntau yam kev tshuaj ntsuam xyuas cov khoom lag luam feem ntau yog tsim raws li kev siv sib txawv, xws li lub teeb ci, dej tsis muaj zog, sieving feem, resin thiab tshauv cov ntsiab lus, cov ntsiab lus cellulose, hardness (sawv cev lignin cov ntsiab lus), lub cev lub zog ntawm cov khoom. daim ntawv pulp thiab lwm yam ntsuas uas cuam tshuam rau kev ua haujlwm ntawm cov khoom tiav.Cov ntsuas no yog cov kev xav tau tshwj xeeb ntawm cov tawv nqaij fiber ntau morphology thiab nws cov purity.Hauv kev tsim cov ntawv, xaiv ib lub pulp uas tsim nyog, los yog ob los yog ntau dua pulps ntawm cov khoom sib txawv tuaj yeem xaiv tau raws li qhov tsim nyog.
