Non-ionic cellulose ether yog cov khoom siv tshuaj tseem ceeb uas yuav tsum tau ua los ntawm cov khoom siv hauv tsev thiab kev lag luam txheej. Tam sim no, raws li keeb kwm yav dhau los ntawm kev nce ntxiv ntawm tag nrho cov txiaj ntsig ntawm kev tsim kho hauv tsev thiab kev nthuav dav ntawm cov txheej txheem ua lag luam, nws cov kev xav tau kev lag luam txuas ntxiv mus ntxiv.
Cellulose ether yog hais txog cov khoom siv polymer nrog cov qauv ether ua los ntawm cellulose. Nws yog soluble hauv dej, dilute alkali tov thiab organic hnyav, thiab muaj thermos-plasticity. Nws yog dav siv nyob rau hauv cov khoom noj, tshuaj, tshuaj txhua hnub, kev tsim kho, textile, roj av, tshuaj, nws yog dav siv nyob rau hauv coatings, electronics thiab lwm yam teb. Raws li cov khoom sib txawv ionization, cellulose ethers tuaj yeem muab faib ua peb pawg: non-ionic cellulose ethers, ionic cellulose ethers, thiab mixed cellulose ethers.
Piv nrog ionic thiab sib xyaw cellulose ethers, non-ionic cellulose ethers muaj qhov kub zoo dua, tiv thaiv ntsev, dej solubility, tshuaj lom neeg ruaj khov, txo tus nqi thiab cov txheej txheem paub tab, thiab tuaj yeem siv ua cov yeeb yaj kiab tsim, Emulsifiers, thickeners, dej tuav. Cov neeg sawv cev, cov ntawv khi, cov stabilizers thiab lwm yam tshuaj ntxiv tau siv dav hauv kev tsim kho, txheej txheej, tshuaj txhua hnub, zaub mov, textiles thiab lwm yam kev lag luam, thiab kev lag luam muaj kev cia siab rau kev loj hlob. Tam sim no, cov uas tsis yog-ionic cellulose ethers feem ntau suav nrog hydroxypropyl methyl (HPMC), hydroxyethyl methyl (HEMC), methyl (MC), hydroxypropyl (HPC), hydroxyethyl (HEC) thiab lwm yam.
Nonionic cellulose ether yog cov khoom siv tshuaj tseem ceeb uas yuav tsum tau ua los ntawm cov khoom siv hauv tsev thiab kev lag luam coatings. Tam sim no, kev lag luam thov rau nws tseem loj hlob nyob rau hauv keeb kwm yav dhau los ntawm kev nce ntxiv ntawm tag nrho cov txiaj ntsig ntawm kev tsim kho hauv tsev thiab kev nthuav dav ntawm kev lag luam coatings. Raws li cov ntaub ntawv los ntawm National Bureau of Statistics, tag nrho cov txiaj ntsig ntawm kev tsim kho hauv lub tebchaws hauv thawj peb lub hlis twg ntawm 2022 yog 20624.6 billion yuan, nce 7.8% piv nrog tib lub sijhawm xyoo tas los. Hauv cov ntsiab lus no, raws li "2023-2028 Tuam Tshoj Nonionic Cellulose Ether Kev Lag Luam Daim Ntawv Thov Kev Lag Luam Kev Lag Luam thiab Kev Tshawb Fawb Txog Kev Tshawb Fawb" tso tawm los ntawm Xin si jie Kev Lag Luam Kev Tshawb Fawb Chaw, qhov muag ntim ntawm cov khoom lag luam hauv tsev nonionic cellulose ether hauv 2022 yuav ncav cuag 172,000 tons. , ib xyoos ib zaug nce ntawm 2.2%.
Ntawm lawv, HEC yog ib qho ntawm cov khoom lag luam tseem ceeb hauv kev lag luam uas tsis yog-ionic cellulose ether. Nws yog hais txog cov khoom siv tshuaj npaj los ntawm paj rwb pulp ua raw khoom los ntawm alkalization, etherification, thiab tom qab kho. Nws tau siv rau hauv kev tsim kho, Nyiv, thiab lwm yam. Tshuaj lom neeg, kev tiv thaiv ib puag ncig thiab lwm yam kev lag luam tuaj yeem siv dav. Tsav los ntawm kev loj hlob tsis tu ncua ntawm kev thov, qib kev tsim khoom ntawm cov tuam txhab HEC hauv tsev tau txhim kho tas li. Ntau lub tuam txhab ua lag luam nrog cov thev naus laus zis thiab cov txiaj ntsig zoo tau tshwm sim, xws li Yi Teng Cov Khoom Tshiab, Yin Ying Cov Khoom Tshiab, thiab TAIAN Rui tai, thiab qee cov khoom tseem ceeb ntawm cov lag luam no tau mus txog thoob ntiaj teb. qib siab. Tsav los ntawm txoj kev loj hlob sai ntawm kev lag luam ntu yav tom ntej, txoj kev loj hlob ntawm kev lag luam hauv tsev uas tsis yog-ionic cellulose ether yuav zoo.
Xin Si Jie cov kws tshuaj ntsuam xyuas kev lag luam tau hais tias tsis yog-ionic cellulose ether yog cov khoom siv polymer nrog kev ua tau zoo thiab kev siv dav. Tsav los ntawm txoj kev loj hlob sai ntawm nws cov lag luam, tus naj npawb ntawm cov lag luam hauv tsev hauv daim teb no tau nce. Lub tuam txhab tseem ceeb suav nrog Hebei SHUANG NIU, Tai An Rui Tai, Shandong Yi Teng, Shang Yu Chuang Feng, North Tian Pu, Shandong He da, thiab lwm yam. Nyob rau hauv cov ntsiab lus no, homogeneity ntawm domestic uas tsis yog-ionic cellulose ether cov khoom yog ua ntau thiab nrov. Nyob rau hauv lub neej yav tom ntej, cov tuam txhab hauv zos yuav tsum tau ceev cov kev tshawb fawb thiab kev loj hlob ntawm high-end thiab cov khoom sib txawv, thiab kev lag luam muaj chav loj loj rau kev loj hlob.
