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

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 khona ho senyeha, 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.
