Cellulose, hydroxyethil ether (MW 1000000)

Cellulose hydroxyethil etheryog ib tug derivative ntawm cellulose, lub ntuj polymer pom nyob rau hauv cov phab ntsa ntawm tes ntawm cov nroj tsuag. Lub hydroxyethyl ether Kev hloov kho yuav cuam tshuam rau cov pawg hydroxyethyl rau lub cellulose qauv. Lub cev hnyav molecular (MW) teev raws li 1,000,000 yuav hais txog qhov nruab nrab molecular hnyav ntawm cellulose hydroxyethy ether. Nov yog qee cov ntsiab lus tseem ceeb txog cov cellulose hydroxyethyl ether nrog lub cev hnyav ntawm 1,000,000:

1. Tus qauv tshuaj:
   • Cellulose hydroxyethyl ether yog muab los ntawm cellulose los ntawm ethylene oxide, ua rau cov lus qhia ntawm hydroxyethyl pawg rau lub cellulose.
2. Molecular hnyav:
   • Qhov hnyav molecular ntawm 1,000,000 qhia txog qhov nruab nrab molecular hnyav ntawm lub cellulose hydroxyethy ether. Tus nqi no yog kev ntsuas ntawm qhov nruab nrab loj ntawm cov ntaub pua npab hauv cov qauv.
3. Lub cev lub cev:
   • Cov yam ntxwv tshwj xeeb ntawm cellulose hydroxyethy, viscosity, thiab gel-accosity zoo li tus degree ntawm qhov poob (DS) thiab cov molecular hnyav. Cov hnyav dua molecular yuav cuam tshuam cov viscosity thiab rheatorian tus cwj pwm ntawm kev daws teeb meem.
4. Solubility:
   • Cellulose hydroxyethyl ether yog feem ntau soluble hauv dej. Cov qib degree hloov chaw thiab lub cev hnyav tuaj yeem cuam tshuam nws cov solubility thiab kev xav tau ntawm uas nws cov kev daws teeb meem.
5. Cov Ntawv Thov:
   • Cellulose hydroxyethil ether nrog molecular ceeb thawj ntawm 1,000,000 tuaj yeem nrhiav tau cov ntawv thov hauv ntau qhov kev lag luam:
     • Kws Tshuaj: Nws tuaj yeem siv rau hauv cov tshuaj tswj tso tawm, cov ntsiav tshuaj pleev xim, thiab lwm cov tshuaj thov tshuaj.
     • Cov ntaub ntawv tsim kho: hauv tshuaj khib, plaster, thiab pobzeb cov nplaum los txhim kho cov dej tuav thiab ua haujlwm.
     • Txheej thiab cov yeeb yaj kiab: hauv kev tsim cov txheej txheem thiab cov yeeb yaj kiab rau nws cov yeeb yaj kiab-ua yeeb yaj kiab.
     • Cov khoom siv saib xyuas tus kheej: hauv cov tshuaj pleev ib ce thiab cov kev saib xyuas tus kheej rau nws cov khoom siv tuab thiab ruaj khov.
6. Rheological tswj:
   • Qhov kev sib ntxiv ntawm cov cellulose hydroxyethyl ether tuaj yeem muab kev tswj hwm ntawm cov hom kev daws teeb meem, ua rau nws muaj txiaj ntsig zoo hauv qhov chaw viscosity tswj yog qhov tseem ceeb.
7. Biodegradability:
   • Cellulose neeg muaj kev pab, suav nrog hydroxyethyl ether derivarives, feem ntau biodegradable, pab txhawb rau lawv cov phooj ywg ib puag ncig.
8. Synthesis:
   • Cov synthesis cuam tshuam cov tshuaj tiv thaiv ntawm cellulose nrog ethylene oxide nyob rau hauv muaj alkali. Cov degree ntawm kev hloov pauv thiab txoj kev hnyav tuaj yeem tswj tau thaum lub sijhawm ua hluav taws xob.
9. Tshawb nrhiav thiab kev txhim kho:
   • Cov kws tshawb nrhiav thiab cov qauv yuav xaiv cov cellulection hydroxyethy raws li kev ua haujlwm hnyav thiab qib degree hloov mus ua tiav cov khoom uas xav tau hauv cov ntawv thov sib txawv.

Nws yog ib qho tseem ceeb kom nco ntsoov tias cov khoom thiab cov ntawv thov ntawm cov cellulose hydroxyethil Ethories, thiab cov ntaub ntawv tshwj xeeb muab cov ntsiab lus dav dav. Cov ntaub ntawv ntxaws ntxaws muab los yog cov chaw tsim khoom lossis cov chaw muag khoom yog qhov tseem ceeb rau kev nkag siab txog cov khoom lag luam hydroxyethyl aixyyl Enteres.
