Selulose, hydroxyethyl ether (MW 1000000)

Cellulose hydroxyethyl etherke se tswang ho cellulose, e leng polymer ya tlhaho e fumanwang maboteng a dimela tsa sele. Phetoho ya hydroxyethyl ether e kenyeletsa ho hlahisa dihlopha tsa hydroxyethyl sebopehong sa cellulose. Boima ba molek'hule (MW) bo boletsweng e le 1,000,000 mohlomong bo bolela boima bo tloaelehileng ba molek'hule ba ether ya cellulose hydroxyethyl. Mona ke dintlha tse ding tsa bohlokwa mabapi le ether ya cellulose hydroxyethyl ether e nang le boima ba molek'hule ba 1,000,000:

1. Sebopeho sa Lik'hemik'hale:
   • Cellulose hydroxyethyl ether e nkuwa ho tsoa ho cellulose ka ho e kopanya le ethylene oxide, e leng se fellang ka ho kenngoa ha lihlopha tsa hydroxyethyl mokokotlong oa cellulose.
2. Boima ba limolek'hule:
   • Boima ba limolek'hule ba 1,000,000 bo bontša boima ba limolek'hule ba cellulose hydroxyethyl ether. Boleng bona ke tekanyo ea boima bo tloaelehileng ba liketane tsa polymer sampole.
3. Thepa ea 'Mele:
   • Thepa e ikgethang ya mmele ya cellulose hydroxyethyl ether, jwalo ka ho qhibiliha, ho teteana, le bokgoni ba ho etsa gel, e itshetlehile hodima mabaka a kang tekanyo ya phetolo (DS) le boima ba dimolek'hule. Boima bo hodimo ba dimolek'hule bo ka ama ho teteana le boitshwaro ba rheological ba ditharollo.
4. Ho qhibiliha ha metsi:
   • Cellulose hydroxyethyl ether hangata e qhibiliha ka metsing. Tekanyo ea ho nkeloa sebaka le boima ba limolek'hule li ka ama ho qhibiliha ha eona le mahloriso ao e etsang litharollo tse hlakileng ho 'ona.
5. Likopo:
   • Cellulose hydroxyethyl ether e nang le boima ba limolek'hule ba 1,000,000 e ka fumana lits'ebetso liindastering tse fapaneng:
     • Meriana: E ka sebelisoa mefuteng ea meriana e lokolloang ka taolo, liphahlo tsa matlapa, le lits'ebetsong tse ling tsa meriana.
     • Lisebelisoa tsa Kaho: Ka har'a seretse, plaster, le likhomaretsi tsa thaele ho ntlafatsa ho boloka metsi le ho sebetsa hantle.
     • Likobo le Lifilimi: Tlhahisong ea likobo le lifilimi bakeng sa thepa ea tsona ea ho etsa filimi.
     • Lihlahisoa tsa Tlhokomelo ea Motho ka Mong: Litlolong le linthong tsa tlhokomelo ea motho ka mong ka lebaka la thepa ea eona ea ho tenya le ho tsitsisa.
6. Taolo ea Mafu a Tšoaetso:
   • Ho eketsoa ha cellulose hydroxyethyl ether ho ka fana ka taolo hodima thepa ya rheological ya ditharollo, e leng se etsang hore e be ya bohlokwa ditokisetsong moo taolo ya viscosity e leng ya bohlokwa.
7. Ho bola ha lintho tse phelang:
   • Li-ether tsa cellulose, ho kenyeletsoa le li-derivatives tsa hydroxyethyl ether, hangata lia bola, li tlatsetsa boemong ba tsona bo sireletsang tikoloho.
8. Ho kopanya:
   • Ho kopanngoa hona ho kenyelletsa karabelo ea cellulose le ethylene oxide boteng ba alkali. Tekanyo ea ho nkeloa sebaka le boima ba limolek'hule li ka laoloa nakong ea ts'ebetso ea ho kopanngoa.
9. Patlisiso le Nts'etsopele:
   • Bafuputsi le baetsi ba di-formula ba ka kgetha di-ether tse ikgethang tsa cellulose hydroxyethyl ho latela boima ba dimolek'hule le tekanyo ya phetolo ho fihlella dibopeho tse lakatsehang ditshebedisong tse fapaneng.

Ho bohlokoa ho hlokomela hore thepa le ts'ebeliso ea cellulose hydroxyethyl ether li ka fapana ho latela litšobotsi tsa eona tse ikhethang, 'me tlhahisoleseling e boletsoeng e fana ka kakaretso e akaretsang. Lintlha tse qaqileng tsa tekheniki tse fanoeng ke bahlahisi kapa bafepedi li bohlokoa bakeng sa ho utloisisa sehlahisoa se ikhethileng sa cellulose hydroxyethyl ether se amehang.
