Cellulose ether?

Txoj kev txhim kho ntawm cov tsis-ionic cellulose kev lag luam ether yog kev txhim kho, qib siab thiab sib txawv yog cov lus qhia tseem ceeb ntawm kev txhim kho yav tom ntej

Cellulose ete yog hais txog cov polymer sib txuas nrog cov qauv ethered ua los ntawm cellulose. Nws yog soluble hauv dej, dilute alkali daws thiab organic kuab tshuaj, thiab muaj thermoplasticity. Nws yog dav siv hauv zaub mov, tshuaj, kev tsim kho txhua hnub, tsim kho, roj av, nws yog dav siv hauv cov txheej txheem, khoom siv hluav taws xob thiab lwm thaj teb. Raws li cov khoom sib txawv ntawm ionization, cov cellulose cov neeg muaj peev xwm faib ua peb pawg: tsis muaj kev pab cuam cellulose cellulose, ionic cellulose cov neeg muaj kev hais ua ke.

Piv nrog ionic thiab sib xyaw cellulose cellulose muaj cov neeg muaj kev tiv thaiv cov dej, thiab siv tshuaj ntsuab, khoom noj, cov khoom noj, cov ntawv sau thiab lwm yam teb, thiab lwm yam teb, thiab lwm daim teb, thiab Kev ua lag luam muaj kev cia siab rau kev txhim kho. Ntawm tam sim no, cov neeg muaj kev cuam tshuam cellulose cellulose feem ntau suav nrog HydroxyPropyl methyl (MHCC), HydroxyRropyl (HPC), Hydroxyethyl (HOLCY), Hydroxyethyl (HEC) thiab li ntawd.

Tsis yog ib qho kev siv tshuaj lom neeg tseem ceeb uas yuav tsum muaj tshuaj lom neeg siv lub tsev kev lag luam thiab kev lag luam. Tam sim no, kev ua lag luam xav tau rau nws tseem loj hlob nyob rau hauv keeb kwm kev nce qib hauv kev tsim kho kev tsim kho ntawm kev tsim kho hauv tsev thiab kev nthuav dav txuas ntxiv ntawm cov txheej txheem ua lag luam. Raws li cov ntaub ntawv los ntawm Lub Tebchaws National Retistics, tag nrho cov zis cov txiaj ntsig ntawm 2022 yog 20624.6 Billion Yuan, nce 78% piv nrog rau tib lub sijhawm xyoo tas los. Nyob rau hauv cov ntsiab lus no, raws li "2023-2028 Tuam Tshoj Nether Cov Kev Tshawb Fawb Kev Lag Luam Tsis Tau Txais thiab Kev Tsim Kho Kev Lag Luam Kev Lag Luam Kev Lag Luam Kev Lag Luam Kev Lag Luam Tsis Tau Txais"

Ntawm lawv, HEC yog ib qho ntawm cov khoom siv tseem ceeb hauv cov khoom lag luam tsis muaj ionic istet. Nws yog hais txog cov khoom siv tshuaj lom tau npaj los ntawm cov paj rwb pulp li cov khoom siv los ntawm kev sib tw, etherization, thiab kev kho tom qab. Nws tau siv hauv kev tsim kho, Nyiv, thiab lwm yam tshuaj lom neeg, kev tiv thaiv ib puag ncig thiab lwm daim teb tuaj yeem siv dav. Tsav los ntawm kev loj hlob txuas mus ntxiv, cov kev siv thev naus laus zis ntau lawm ntawm HEC cov lag luam tau txhim kho tas li. Ntau cov lag luam nrog thev naus laus zis thiab cov ntsiab lus sib npaug tau tshwm sim, thiab tai cov khoom lag luam tshiab, thiab qee cov khoom lag luam tseem ceeb, thiab qee cov khoom siv tseem ceeb Qib siab. Tsav los ntawm kev txhim kho sai ntawm kev ua lag luam ntu yav tom ntej, kev txhim kho kev txhim kho ntawm cov kev lag luam ntawm ether ether ether yuav muaj qhov zoo.

XinsiJie Kev Lag Luam Kev Lag Luam tau hais tias tsis muaj ionic cellulose ether yog hom ntawm cov khoom siv polymer nrog cov khoom siv zoo nkauj thiab thoob plaws. Tsav los ntawm kev txhim kho sai ntawm nws kev ua lag luam, tus naj npawb ntawm cov lag luam hauv tsev hauv tsev hauv daim teb no nce. Lub ntsiab lag luam tseem ceeb suav nrog Hebei Shuangniu, Taian Rewiai, Shandong ETON, North Tianpu, Shand kev sib tw ua rau muaj tsiv zuj zus, North lub taub hau, thiab lwm yam. Nyob rau hauv cov ntsiab lus no, homogeneity ntawm cov khoom tsis yog-ionic cellulose ether cov khoom lag luam tau ntau dua thiab muaj koob meej. Yav tom ntej, cov tuam txhab hauv zos yuav tsum tau ceev cov kev tshawb fawb thiab kev txhim kho cov khoom lag luam siab thiab cov kev lag luam muaj ib chav loj loj rau kev loj hlob.
