Mehopolo ea mantlha le classifition of cellulose ether

Celloulose Ether ke sehlopha se sa fetoheng ea polyudile se tsoang ho Cellloulose, tlhaho Polysaccharide e fumanehang marakong a cel. E-'E-' e-ba-celthe e indastering ea bona ea sele cellulo e sebelisoa haholo indasteri ea bona e ikhethang, e kenyeletsang ho boloka metsi, ho etsa lifilimi le bokhoni ba ho tsitsisa. Mona ke mehopolo ea mantlha le likheo tsa cellulose ether:

Mehopolo ea mantlha:

1. Sebopeho sa cellulose:
   • Cellloulose e entsoe ka likarolo tsa glucose e hokahantsoeng ke Β (1 → 4) maqhama a glycsidic. E na le liketane tse telele, tse tšelang tse fanang ka tšehetso ea sebopeho ho jala lisele.
2. Phapanyetsano:
   • E-'Ethe e hlahisoa ka phetoho ea khemisi ea Celluulo ka ho hlahisa lihlopha tsa Ether (-chCHohh, jj).
3. Ts'ebetso:
   • Kenyelletso ea litso tsa Ether e fetola thepa ea lik'hemik'hale le nama ea selefounu, e fanang ka lisele, ho boloka metsi le ho theha fono.
4. Biodegradadical:
   • E-le Senseese e Behiloeng ka Li-celdgrate ke li-polymers tsa Bill tsa Bill.

Classific:

Ethen e 'ngoe e khethiloeng e thehiloe ho mofuta oa linyeoe tsa lilum tsa cellulo le boemo ba bona ba sebaka. Mefuta e Tloaelehileng ea EMS ea Cellu Boudd e kenyelletsa:

1. Methyl cerelosese (MC):
   • Methyl celluloulose e hlahisoa ka ho kenyelletsa methyl (-Ch3) lihlopha ho molikolong oa cellulose.
   • E qhibiliha ka metsing a batang 'me e hlakisoa pepenene, tharollo ea lifate. Mc o sebelisoa e le bolo ea letsoho, se hlolla, 'me filimi e ne e le ea mehleng e fapaneng.
2. Hydroxeeyl cellulolose (Hec):
   • Hydroxethyl Cellulouse ea fumanoa ka ho hlahisa hydroxethyl (-Chech2Hoh) Sehlopha ho Molek'hulese ea celleng.
   • E fana ka bolokolohi ba ho boloka metsi le ho etsa hore e etse hore e sebelisoe ka lipente, merabe, litlolo, le meriana, litlolo.
3. HydroxypropypropyLe Methyl Cellulose (HPMC):
   • HydroxypropypropinyL methyl methyl methyl ke mothapo oa lithyl cellulolose le hydroxypropyl celluulose.
   • E fana ka mefuta-lekaneng ea thepa e kang alloubility ea metsi, taolo ea pono le theknoloji ea lifilimi. HPMC e sebelisoa haholo ka ho haha, meriana le lihlahisoa tsa tlhokomelo ea motho.
4. Carboxexethyl cellulolose (cmc):
   • CilboxexeMethyl Cellulosese e hlahisoa ka ho tsebise carboxyMethyl (-och2cooh) sehlopha ho molikolong oa celleng.
   • E qhibiliha ka metsing le ho fumana tharollo e makatsang ka melumo e metle e metle ebile e tsitsa. CMC e sebelisoa lijong, meriana le lits'ebetso tsa indasteri.
5. Ethyl hydroxethyl cellulosese (Ehec):
   • Sehlopha sa Ethyl hydrokethyl se fumanoa ka ho kenyelletsa lihlopha tsa Ethyl le hydroxethyl molek'hule ea selefounu.
   • E fana ka litlamo tsa ho boloka metsi, ho matlafatsa thepa ea matla le thepa ea Rheoloniki ha e bapisoa le bona. Ehec e sebelisoa ka lisebelisoa tsa kaho le lihlahisoa tsa tlhokomelo ea motho.

Ethe ea bo-'mè ea bohlokoa ke litho tsa bohlokoa tsa polyom li tsamaisang likopo tse fapaneng indastering e fapaneng. Phetoho ea bona ea lik'hemik'hale ka lebaka la li-eperital e ngata, e ba etsa litlatsetso tsa bohlokoa ho liforeketsane, likhama tsa lijo le thepa ea lijo. Ho utloisisa mehopolo ea mantlha le likheo tsa 'nete tsa celluulo tsa celluulo ho khetha mofuta o loketseng oa polymer bakeng sa lits'ebetso tse itseng.
