nws lub ntsiab raw cov ntaub ntawv uas yuav tsum tau rau kev tsim covCellulose etherXws li cov paj rwb (lossis ntoo ntawm cov tshuaj lom neeg) thiab qee cov tshuaj lom neeg, ua kua noj qab zib, ethylene dej qab zib, toluene thiab lwm cov ntaub ntawv ib pab pawg. Kev lag luam kev lag luam nce ntxiv ntawm kev lag luam no muaj xws li rwb paj rwb, ntoo pulp ntau lawm ua lag luam thiab qee cov lag luam tshuaj lom neeg. Tus nqi hloov pauv ntawm cov ntaub ntawv tau hais tseg saum toj no yuav muaj sib txawv ntawm cov nqi ntawm cov nqi ntau lawm thiab muag tus nqi ntawm cellulose ether.
Tus nqi ntawm kev ua kom zoo nkauj paj rwb yog qhov tseem ceeb. Siv lub tsev cov khoom siv ntawm cellulose ether ua piv txwv, thaum lub sijhawm muag khoom siv tau suav nrog kev siv cov khoom siv hauv xov tooj no ethotholose. Tus nqi hloov pauv ntawm cov paj rwb rov qab yuav cuam tshuam rau kev tsim cov nqi ntawm cellulose ether. Cov khoom siv tseem ceeb rau kev tsim cov paj rwb yog cov paj rwb. Paj rwb linters yog ib qho ntawm cov khoom hauv cov txheej txheem paj rwb ntau, feem ntau yog siv los tsim cov paj rwb pulp, cov paj rwb, nitroocellulose thiab lwm yam khoom. Kev siv tus nqi thiab kev siv cov paj rwb rinters thiab paj rwb yog qhov sib txawv, thiab nws muaj qee qhov kev sib kho nrog tus nqi hloov kho ntawm paj rwb. Hloov pauv nyob rau hauv tus nqi ntawm paj rwb bowers cuam tshuam tus nqi ntawm refined paj rwb.
Cov kev sib pauv ntse hauv tus nqi ntawm cov nqi paj rwb rov qab muaj feem cuam tshuam ntawm kev tswj hwm ntawm cov nqi ntau lawm, cov txiaj ntsig ntawm cov lag luam hauv kev lag luam no. Thaum tus nqi ntawm lub paj rwb rov qab muaj siab thiab tus nqi ntawm cov nqi ntoo yog qhov siv hluav taws xob, feem ntau rau kev tsim cov neeg muaj kev pab ua ntoo nrog cov viscosity tsis tshua muaj xws li Kws Tshuaj Kho Mob thiab Khoom NojNeeg muaj neeg ua haujlwmCov. Raws li cov ntaub ntawv los ntawm lub vev xaib ntawm National Coreau of Anchin, kuv lub teb chaws cov zis tawm yog 4.31 lab tons. Raws li kev txheeb cais los ntawm Tuam Tshoj Cellulose Kev Lag Luam Kev Lag Luam, nyob rau xyoo 2014, tag nrho cov khoom tawm ntawm cov chaw tsim paj rwb yog 332,000 tons, thiab cov khoom siv ntawm cov khoom siv raw yog muaj qoob loo.
Cov ntaub ntawv raw tseem ceeb rau kev tsim cov khoom siv tshuaj ntsuab yog cov hlau thiab graphite carbon. Tus nqi ntawm cov hlau thiab graphite carbon account rau qhov sib npaug ntawm cov nqi tsim khoom ntawm cov khoom siv tshuaj lom. Tus Nqi Ntawm Cov Khoom Siv Raw no yuav muaj qee yam cuam tshuam rau cov nqi tsim khoom thiab muag cov nqe ntawm graphite tshuaj siv.
