Cellulose, hydroxyethyl ether (MW 1000000)

Cellulose hydroxyethyl etherke ntho e nkiloeng ho cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa limela.Phetoho ea hydroxyethyl ether e kenyelletsa ho hlahisa lihlopha tsa hydroxyethyl ho sebopeho sa cellulose.Boima ba limolek'hule (MW) bo boletsoeng e le 1,000,000 mohlomong bo bolela boima ba molek'hule bo tloaelehileng ba cellulose hydroxyethyl ether.Mona ke lintlha tsa bohlokoa mabapi le cellulose hydroxyethyl ether e boima ba molek'hule ea 1,000,000:

1. Sebopeho sa Lik'hemik'hale:
   • Cellulose hydroxyethyl ether e tsoa ho selulose ka ho e arabela ka ethylene oxide, e leng se etsang hore ho be le ho kenngoa ha lihlopha tsa hydroxyethyl mokokotlong oa cellulose.
2. Boima ba Molek'hule:
   • Boima ba limolek'hule ba 1,000,000 bo bonts'a karolelano ea boima ba molek'hule ea cellulose hydroxyethyl ether.Boleng bona ke tekanyo ea boima bo tloaelehileng ba liketane tsa polymer sampole.
3. Thepa ea Sebele:
   • Thepa e khethehileng ea 'mele ea cellulose hydroxyethyl ether, joalo ka ho solubility, viscosity, le bokhoni ba ho etsa gel, e itšetlehile ka lintlha tse kang tekanyo ea ho fetola (DS) le boima ba molek'hule.Boima ba limolek'hule bo phahameng bo ka ama viscosity le boitšoaro ba rheological ea tharollo.
4. Sollubility:
   • Cellulose hydroxyethyl ether hangata e qhibiliha ka metsing.Tekanyo ea ho kenya sebaka le boima ba limolek'hule bo ka ama ho qhibiliha ha eona le ho tsepamisa mohopolo moo e etsang tharollo e hlakileng.
5. Lisebelisoa:
   • Cellulose hydroxyethyl ether e boima ba molek'hule ea 1,000,000 e ka fumana lits'ebetso liindastering tse fapaneng:
     • Meriana ea Meriana: E ka 'na ea sebelisoa ho etsa litlhare tse laoloang, li-tablet, le lisebelisoa tse ling tsa meriana.
     • Lisebelisoa tsa Kaho: Ka seretse, samente, le likhomaretsi tsa lithaele ho ntlafatsa ho boloka metsi le ho sebetsa.
     • Liaparo le Lifilimi: Tlhahisong ea liphahlo le lifilimi bakeng sa thepa ea eona ea ho etsa lifilimi.
     • Lihlahisoa tsa Tlhokomelo ea Motho: Ka litlolo le lintho tsa tlhokomelo ea botho bakeng sa thepa ea eona e teteaneng le e tsitsitseng.
6. Taolo ea Rheological:
   • Ho eketsoa ha cellulose hydroxyethyl ether ho ka fana ka taolo holim'a thepa ea rheological ea tharollo, ho etsa hore e be ea bohlokoa ka ho hlophisoa moo ho laolang viscosity ho hlokahalang.
7. Biodegradability:
   • Li-cellulose ethers, ho kenyeletsoa le tse nkiloeng ho hydroxyethyl ether, hangata lia senyeha, e leng se tlatselletsang ho boemo ba tsona ba tikoloho.
8. Synthesis:
   • Tšimoloho e kenyelletsa karabelo ea cellulose ka ethylene oxide boteng ba alkali.Tekanyo ea ho kenya sebaka le boima ba limolek'hule bo ka laoloa nakong ea ts'ebetso ea ho kopanya.
9. Lipatlisiso le Ntlafatso:
   • Bafuputsi le baetsi ba lihlahisoa ba ka khetha li-cellulose hydroxyethyl ethers tse thehiloeng ho boima ba limolek'hule le tekanyo ea ho fetola ho finyella thepa e lakatsehang lits'ebetsong tse fapaneng.

Ke habohlokoa ho hlokomela hore thepa le lisebelisoa tsa cellulose hydroxyethyl ether li ka fapana ho latela litšobotsi tsa eona tse khethehileng, 'me boitsebiso bo boletsoeng bo fana ka kakaretso ea kakaretso.Lintlha tse qaqileng tsa tekheniki tse fanoeng ke bahlahisi kapa barekisi li bohlokoa bakeng sa ho utloisisa sehlahisoa se ikhethileng sa cellulose hydroxyethyl ether eo ho buuoang ka eona.
