Cellulose Ethers-HPMC/CMC/HEC/MC/EC

ha re hlahlobeng senotlololi-cellulose ethers: HPMC (Hydroxypropyl Methylcellulose), CMC (Carboxymethyl Cellulose), HEC (Hydroxyethyl Cellulose), MC (Methyl Cellulose), le EC (Ethyl Cellulose).

1. Hydroxypropyl Methylcellulose (HPMC):
   • Thepa:
     • Solubility: Ho qhibiliha ha metsi.
     • Ts'ebetso: E sebetsa joalo ka setei, se tlamang, sa pele sa filimi, le moemeli oa ho boloka metsi.
     • Lisebelisoa: Lisebelisoa tsa ho haha ​​(liretse, li-adhesives tsa lithaele), meriana (liaparo tsa letlapa, lihlahisoa tse lokolotsoeng tse laoloang), le lihlahisoa tsa tlhokomelo ea botho.
2. Carboxymethyl Cellulose (CMC):
   • Thepa:
     • Solubility: Ho qhibiliha ha metsi.
     • Mosebetsi: E sebetsa joalo ka setei, se tsitsisa le ho boloka metsi.
     • Likopo: Indasteri ea lijo (e le setsi sa ho tiisa le ho tsitsisa), meriana, masela, le lihlahisoa tsa tlhokomelo ea botho.
3. Hydroxyethyl Cellulose (HEC):
   • Thepa:
     • Solubility: Ho qhibiliha ha metsi.
     • Mosebetsi: E sebetsa e le setei, se tlamang le se bolokang metsi.
     • Lisebelisoa: Lipente le lirafshoa, lihlahisoa tsa tlhokomelo ea botho (li-shampoo, litlolo), le thepa ea kaho.
4. Methyl Cellulose (MC):
   • Thepa:
     • Solubility: Ho qhibiliha ha metsi.
     • Ts'ebetso: E sebetsa joalo ka motenya, ea tlamang, le moetsi oa lifilimi.
     • Likopo: Indasteri ea lijo, meriana, le thepa ea kaho.
5. Ethyl Cellulose (EC):
   • Thepa:
     • Solubility: Ha e qhibilihe metsing (e qhibilihang ka har'a metsoako ea tlhaho).
     • Mosebetsi: E sebelisoa e le filimi-ea pele le thepa ea ho roala.
     • Lisebelisoa: Meriana (ho roala matlapa), liphahlo bakeng sa lihlahisoa tse laoloang.

Litšobotsi tse Tloaelehileng:

• Ho qhibiliha ha Metsi: HPMC, CMC, HEC, le MC ha li qhibilihe ka metsing, ha EC hangata e sa qhibilihe metsing.
• Ho teteana: Li-ether tsena tsohle tsa cellulose li bonts'a thepa ea ho teteana, e kenyang letsoho taolong ea viscosity lits'ebetsong tse fapaneng.
• Tlhahiso ea Lifilimi: Tse 'maloa, ho kenyeletsoa HPMC, MC, le EC, li ka etsa lifilimi, tsa li etsa hore li be molemo ho lijalo le lits'ebetsong tsa meriana.
• Biodegradability: Ka kakaretso, li-cellulose ethers li ka senyeha habonolo, li ikamahanya le litloaelo tse baballang tikoloho.

Ether e 'ngoe le e' ngoe ea cellulose e na le litšobotsi tse ikhethang tse etsang hore e tšoanelehe bakeng sa lits'ebetso tse itseng. Khetho har'a tsona e ipapisitse le lintlha tse kang ts'ebetso e lakatsehang, litlhoko tsa solubility, le indasteri / kopo e reriloeng. Ho bohlokoa ho nahana ka lintlha tsena le ho shebana le lintlha tsa tekheniki ha u khetha li-cellulose ethers bakeng sa sebopeho se itseng kapa tšebeliso e itseng.
