Kima tuam txhab yog cov kws tshaj lij cellulose ether Hoobkas hauv Suav teb. Nws tsim cov qib sib txawv ntawm cellulose ether thiab hloov kho cellulose ether.
Cellulose Ether& Nws Cov Kev Lag Luam Kev Lag Luam Kev Lag Luam Hauv 2022:
Nyob rau hauv 2021, lub ntiaj teb no noj cellulose ethers, dej-soluble polymers tsim los ntawm tshuaj hloov kho ntawm cellulose, yog ze rau 1.1 lab tons. Ntawm tag nrho lub ntiaj teb cellulose ether tsim nyob rau hauv 2021, 43% yog los ntawm Asia (Tuam Tshoj suav rau 79% ntawm cov neeg Esxias ntau lawm), Western Europe suav txog 36%, thiab North America suav txog 8%. Kev noj cov cellulose ethers yuav tsum loj hlob ntawm qhov nruab nrab txhua xyoo ntawm 2.9% los ntawm 2021 txog 2023, nrog kev thov kev loj hlob hauv kev lag luam loj hauv North America thiab Western Europe tau qis dua lub ntiaj teb nruab nrab, ntawm 1.2% thiab 1.3%, feem. , thaum qhov kev thov loj hlob ntawm Asia thiab Oceania yuav siab dua qhov nruab nrab ntawm lub ntiaj teb, ntawm 3.8%; Tuam Tshoj txoj kev xav tau kev loj hlob yog 3.4%, thiab kev loj hlob ntawm Central thiab Eastern Europe yuav tsum yog 3.8%.
Thaj chaw uas muaj kev noj ntau tshaj plaws ntawm cellulose ether hauv ntiaj teb xyoo 2022 yog Asia, suav txog 40% ntawm tag nrho cov kev siv, thiab Tuam Tshoj yog lub zog tsav tsheb loj. Western Europe thiab North America suav txog 19% thiab 11% ntawm kev siv thoob ntiaj teb, feem. Carboxymethyl cellulose (CMC) suav txog 50% ntawm tag nrho kev noj cellulose ethers hauv 2022, tab sis nws txoj kev loj hlob yuav tsum qis dua li ntawm cellulose ethers tag nrho yav tom ntej. Methyl cellulose / hydroxypropyl methyl cellulose (MC / HPMC) suav txog 33% ntawm tag nrho cov khoom noj, hydroxyethyl cellulose (HEC) suav txog 13%, thiab lwm yam cellulose ethers suav txog li 3%.
Cellulose ethers yog dav siv los ua thickeners, binders, emulsifiers, humectants thiab viscosity tswj cov neeg ua haujlwm. Daim ntawv thov kawg suav nrog sealants thiab grout, khoom noj khoom haus, xim thiab txheej, thiab tshuaj noj thiab tshuaj noj. Ntau yam cellulose ethers kuj sib tw nrog ntau lub lag luam thiab nrog rau lwm cov khoom lag luam uas muaj cov haujlwm zoo sib xws, xws li hluavtaws dej-soluble polymers thiab ntuj dej-soluble polymers. Synthetic water-soluble polymers muaj xws li polyacrylates, polyvinyl alcohols, thiab polyurethanes, thaum ntuj dej-soluble polymers feem ntau muaj xws li xanthan gum, carrageenan, thiab lwm yam pos hniav. Qhov kev xaiv kawg ntawm polymer rau ib daim ntawv thov tshwj xeeb yuav nyob ntawm qhov kev lag luam tawm ntawm qhov muaj, kev ua tau zoo thiab tus nqi, nrog rau kev siv tau zoo.
Xyoo 2022, tag nrho lub ntiaj teb carboxymethyl cellulose (CMC) kev ua lag luam tau mus txog 530,000 tons, uas tuaj yeem muab faib ua qib kev lag luam (Tshuag tov), qib semi-purified thiab qib siab purity. Qhov tseem ceeb tshaj plaws ntawm kev siv CMC yog cov tshuaj ntxuav tes, uas siv qib CMC, uas suav txog li 22% ntawm kev siv; daim ntawv thov cov roj av suav txog li 20%; thiab zaub mov additives suav txog li 13%. Hauv ntau thaj tsam, CMC cov kev lag luam tseem ceeb yog cov paub tab, tab sis kev thov los ntawm kev lag luam roj av tsis muaj zog thiab khi rau cov nqi roj. CMC tseem ntsib kev sib tw los ntawm lwm yam khoom, xws li hydrocolloids uas tuaj yeem muab kev ua tau zoo tshaj plaws hauv qee yam kev siv. Kev thov rau cellulose ethers uas tsis yog CMC yuav raug tsav los ntawm kev tsim kho siv, suav nrog cov txheej txheem saum npoo, nrog rau cov khoom noj, tshuaj thiab kev siv tshuaj kho tus kheej.
CMC kev lag luam kev lag luam tseem muaj qhov sib cais, nrog rau 5 cov neeg tsim khoom lag luam suav nrog tsuas yog 22% ntawm tag nrho cov peev txheej. Tam sim no, Suav lag luam-qib CMC cov neeg tsim khoom ua lag luam, suav txog 48% ntawm tag nrho cov peev txheej. Kev ua lag luam huv-qib CMC yog qhov tseem ceeb hauv kev tsim khoom, nrog rau tsib lub tuam txhab ua lag luam suav nrog 53% ntawm cov peev txheej tsim khoom.
Kev sib tw toj roob hauv pes ntawm CMC yog qhov sib txawv ntawm lwm cov cellulose ethers, nrog rau qhov tsis tshua muaj kev cuam tshuam rau kev nkag, tshwj xeeb tshaj yog rau cov khoom lag luam qib CMC nrog purity ntawm 65% mus rau 74%. Kev ua lag luam rau cov khoom zoo li no tau tawg ntau dua thiab ua tiav los ntawm Tuam Tshoj cov tuam txhab. Kev ua lag luam huv-qib CMC yog qhov muaj zog dua, nrog rau purity ntawm 96% lossis siab dua. Xyoo 2022, lub ntiaj teb kev noj cellulose ethers uas tsis yog CMC yog 537,000 tons, thiab cov ntawv thov tseem ceeb yog kev tsim kho kev lag luam, suav txog 47%; daim ntawv thov kev lag luam khoom noj thiab tshuaj suav txog 14%; Kev lag luam nto coatings suav txog 12%. Lwm cov kev lag luam cellulose ether yog cov concentrated, nrog rau 5 cov neeg tsim khoom lag luam suav nrog 57% ntawm lub peev xwm thoob ntiaj teb.
Zuag qhia tag nrho, daim ntawv thov kev cia siab ntawm cellulose ethers hauv cov khoom noj thiab kev saib xyuas tus kheej yuav tuav lub zog loj hlob. Raws li cov neeg siv khoom xav tau cov zaub mov noj qab haus huv uas muaj roj tsawg thiab qab zib cov ntsiab lus tseem yuav loj hlob ntxiv, txhawm rau kom tsis txhob muaj peev xwm ua xua (xws li gluten), yuav muaj lub sijhawm ua lag luam rau cellulose ethers, uas tuaj yeem muab qhov kev xav tau, Tsis tas li ntawd tsis cuam tshuam rau saj. los yog kev ntxhib los mos. Hauv qee qhov kev siv, cellulose ethers kuj ntsib kev sib tw los ntawm fermentation-derived thickeners, xws li cov pos hniav ntau dua.
