Cellulose ether yog ntuj cellulose (refined macromolle, yog lub pellule pab pawg, yog cov dej ntws los ntawm cov khoom siv hauv qab ntawm cellulose. Cellulose tuaj yeem yaj nyob rau hauv dej, dilute alkali daws thiab organic kuab tshuaj tom qab ethermication, thiab muaj thermoplastic khoom. Cellulose siv ntau yam, siv tau dav, tshuaj, roj av, ntaub ntawv thiab lwm yam kev lag luam. Raws li cov neeg hloov chaw tuaj yeem faib ua ib qho ether thiab sib xyaw ionization ionization faib ua ionization cellulose tau muab faib ua ionization cellulose thiab cov tsis muaj ionic cellulose ether. Tam sim no, iTic cellulose ionhat ionic cov khoom lag luam ntau lawm, yooj yim siv hauv cov khoom lag luam txhua hnub, yog cov khoom lag luam txhua hnub, yog cov khoom lag luam niaj hnub, yog cov khoom lag luam txhua hnub ntawm kev ua lag luam.
Tam sim no, lub ntiaj teb cov ntsiab lus ntawm cellulose ether yog CMC, HPMC thiab MC ob peb, kev siv nyiaj thoob ntiaj teb, HEC suav rau txog 13% ntawm kev ua lag luam thoob ntiaj teb. Qhov tseem ceeb tshaj plaws-siv ntawm carboxymethyl cellulose (cmc) yog xab npum, suav nrog rau kev lag luam hauv chav tsev, thiab lwm yam khoom lag luam feem ntau yog siv hauv cov ntaub ntawv tsim tsev, khoom noj khoom haus.
Ii. Cov ntawv thov nqes nqes
Yav dhau los, vim muaj tsawg kawg thov kev txhim kho ntawm cellulose hauv Suav teb, kom txog rau hnub no, kev thov rau cellulose ether hauv Suav teb. Thiab zoo li Tuam Tshoj lub cellulose ether rau ntawm thaj teb cov ntaub ntawv thov tau muaj cov tshuaj txhua hnub, hauv kev thov kom sai nrog kev txhim kho kev siv tshuab. Piv txwv li, nyob rau hauv cov ntsiav tshuaj tsis ntev los no, cov nroj tsuag ether li cov khoom siv khoom noj muaj qab hau, thiab cov khoom noj khoom noj muaj qhov tseem ceeb ether muaj qhov kev cia siab thiab qhov chaw loj hlob.
Hauv kev ua haujlwm hauv tsev, piv txwv li cellulose, siv cov khoom sib xyaw ua ke ntawm cov khoom siv hauv tsev, yog li lwm cov khoom siv hauv tsev Kev siv tsheb txuas ntxiv txhawm rau txhim kho, thiab cov neeg siv khoom ib puag ncig rau cov ntaub ntawv tsim tsev yog siab dua thiab siab dua rau cov ntaub ntawv tsis muaj ither hauv thaj teb cov ntaub ntawv. Nyob rau lub sijhawm 9th-xyoo, suav nrog kev tsim kho cov tsev nyob hauv nroog thiab kev hloov kho cov tsev laus thiab cov tsev tsis tau ua tiav. Nyob rau hauv thawj ib nrab ntawm 2021, 755 lab square metres ntawm qhov chaw nyob tau pib, nce 5.5 feem pua. Thaj chaw ua tiav ntawm tsev yog 364.81 lab square metres, txog 25.7%. Qhov rov ua dua tshiab ntawm thaj av uas ua tiav yuav tsav cov kev xav tau hauv daim teb ntawm cov ntaub ntawv ether cov ntaub ntawv.
3. Kev sib tw ua lag luam qauv
Tuam Tshoj yog lub cellule thoob ntiaj teb ither zog ntawm cov ntaub ntawv ether ether ether tau ua tiav cov khoom lag luam hauv tsev ether, Japor Finesu, Ntxiv rauKev ntxhov siab ChemistryOb peb ntau dua li kaum txhiab tons ntawm cov lag luam, ntau txhiab cellulose tsim qauv tsim qauv ether, thiab tsis muaj zog me me cov zaub mov ntau dua cov zaub mov ntau thiab cov khoom siv tshuaj.
Plaub, cellulose ether import thiab export xwm txheej
Xyoo 2020, vim muaj kev txawv txawv txawv ntawm kev lag luam txawv teb chaws 'ntau lawm kev nthuav dav ntawm cellulose ether 77,272 tons. Txawm hais tias tus xa tawm ntim ntawm cellulose ether hauv Suav nroo, thaum lub cellulose cellulose feem ntau, thiab cov nqi ntawm export yog tsawg. Tam sim no, cov khoom xa tawm ntawm cellulose volulose ether hauv Suav yog plaub zaug ntawm cov ntim ntshuam, tab sis cov khoom lag luam xa tawm tsawg dua ob zaug tus nqi ntshuam. Hauv thaj teb ntawm cov khoom lag luam high-end-ast domestic etered txheej txheem txheej txheem tseem yog qhov chaw loj rau kev txhim kho.
