Raws li "Tuam Tshoj Cellulose Ether Kev Lag Luam Kev Tshawb Fawb thiab Kev Tshawb Fawb Txog Kev Lag Luam (2022 Edition)" tso tawm los ntawm Li mu Qhia Txog Kev Pab Tswv Yim, cellulose yog cov khoom tseem ceeb ntawm cov phab ntsa ntawm cov nroj tsuag thiab cov khoom siv dav dav thiab ntau tshaj polysaccharide nyob rau hauv cov xwm.Nws suav rau ntau dua 50% ntawm cov ntsiab lus carbon ntawm lub nceeg vaj cog.Ntawm lawv, cov ntsiab lus cellulose ntawm paj rwb yog ze li ntawm 100%, uas yog lub ntuj ntshiab tshaj plaws cellulose.Hauv cov ntoo, cellulose suav txog 40-50%, thiab muaj 10-30% hemicellulose thiab 20-30% lignin.
Kev lag luam txawv teb chaws cellulose ether yog cov paub tab, thiab yog qhov pib monopolized los ntawm cov lag luam loj xws li Dow Chemical, Ashland, thiab Shin-Etsu.Lub peev xwm ntawm cellulose ether ntau lawm ntawm cov tuam txhab txawv teb chaws loj yog kwv yees li 360,000 tons, uas Shin-Etsu ntawm Nyiv thiab Dow ntawm Tebchaws Meskas ob leeg muaj peev xwm tsim tau txog 100,000 tons, Ashland 80,000 tons, thiab Lotte tshaj 40,000 tons (tau txais Samsung -Cov lag luam ntsig txog), plaub lub tuam txhab tsim khoom lag luam muaj peev xwm ntau dua 90% (tsis suav nrog Tuam Tshoj lub peev xwm ntau lawm).Ib qho me me ntawm cov tshuaj-qib, cov khoom noj khoom haus thiab cov khoom siv hauv tsev high-end-qib cellulose ethers xav tau hauv kuv lub teb chaws yog muab los ntawm cov tuam txhab txawv teb chaws paub zoo.
Tam sim no, feem ntau ntawm cov peev txheej ntawm cov khoom siv hauv tsev zoo tib yam-qib cellulose ethers tau nthuav dav hauv Suav teb tau ua rau muaj kev sib tw ntawm cov khoom siv hauv tsev qis-qib, thaum cov khoom lag luam thiab cov khoom noj khoom haus qib nrog cov txheej txheem siab tseem yog lub rooj tsav xwm luv luv ntawm kuv lub teb chaws cellulose ether kev lag luam.
Qhov zoo thiab tsim muaj peev xwm ntawm carboxymethyl cellulose thiab nws cov khoom ntsev hauv kuv lub teb chaws tau zoo heev nyob rau hauv xyoo tas los no, thiab export ntim tau nce xyoo dhau los.Kev lag luam txawv teb chaws feem ntau yog nyob ntawm kuv lub teb chaws cov khoom xa tawm, thiab kev ua lag luam kuj tseem saturated.Chav rau kev loj hlob yav tom ntej yog qhov txwv.
Nonionic cellulose ethers, suav nrog hydroxyethyl, propyl, methylcellulose thiab lawv cov derivatives, muaj kev lag luam zoo yav tom ntej, tshwj xeeb tshaj yog nyob rau hauv high-end daim ntawv thov, uas tseem muaj kev lag luam loj hlob qhov chaw.Xws li cov tshuaj, cov xim qib siab, qib siab ceramics, thiab lwm yam tseem yuav tsum tau tuaj txawv teb chaws.Tseem muaj ntau chav rau kev txhim kho nyob rau hauv theem ntawm kev tsim technology thiab kev tshawb fawb thiab kev loj hlob, thiab tseem muaj peev txheej loj.
Tam sim no, theem ntawm cov cuab yeej siv tshuab rau cov txheej txheem purification hauv tsev yog qhov tsawg, uas txwv kev loj hlob ntawm kev lag luam.Lub ntsiab impurity nyob rau hauv cov khoom yog sodium chloride.Yav dhau los, peb-legged centrifuges tau siv dav hauv kuv lub teb chaws, thiab cov txheej txheem purification yog kev ua haujlwm tsis tu ncua, uas yog siv zog ua haujlwm, siv zog thiab siv cov khoom siv.Cov khoom zoo kuj tseem nyuaj rau kev txhim kho.Feem ntau ntawm cov kab ntau lawm tau xa tawm cov khoom siv txawv teb chaws los txhim kho cov khoom siv qib, tab sis tseem muaj qhov sib txawv ntawm cov automation ntawm tag nrho cov kab ntau lawm thiab txawv teb chaws.Kev txhim kho yav tom ntej ntawm kev lag luam tuaj yeem xav txog kev sib xyaw ua ke ntawm cov khoom siv txawv teb chaws thiab cov khoom siv hauv tsev, thiab cov khoom siv ntshuam hauv cov kev sib txuas tseem ceeb los txhim kho automation ntawm cov kab ntau lawm.Piv nrog rau cov khoom siv ionic, cov khoom tsis yog ionic cellulose ethers muaj cov kev xav tau ntau dua, thiab nws tseem ceeb heev kom tawg los ntawm kev teeb meem hauv kev tsim khoom thiab kev nthuav dav.
