Li-cellulose ethers

Li-cellulose etherske lelapa la li-polymer tse qhibilihang ka metsing tse nkiloeng ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa limela. Li-derivatives tsena li entsoe ka liphetoho tsa lik'hemik'hale tsa cellulose, tse hlahisang lihlahisoa tse fapaneng tse nang le thepa e ikhethang. Li-cellulose ethers li fumana tšebeliso e atileng liindastering tse fapaneng ka lebaka la ho feto-fetoha ha tsona le mesebetsi e ikhethang. Mona ke mefuta e meng e tloaelehileng ea li-cellulose ethers le ts'ebeliso ea tsona:

1. Hydroxyethyl Cellulose (HEC):
   • Lisebelisoa:
     • Lipente le liphahlo: E sebetsa e le mofetoleli o teteaneng le oa rheology.
     • Lihlahisoa tsa tlhokomelo ea motho ka mong: E ​​sebelisoa ka li-shampoo, litlolo, le litlolo e le ntho e matlafatsang le ho tsitsisa.
     • Lisebelisoa tsa kaho: E ntlafatsa ho boloka metsi le ho sebetsa ka har'a seretse le likhomaretsi.
2. Hydroxypropyl Methylcellulose (HPMC):
   • Lisebelisoa:
     • Kaho: E sebelisoa ka seretse, sekhomaretsi, le lirafshoa bakeng sa ho sebetsa hantle le ho khomarela.
     • Meriana ea Meriana: E sebetsa e le setlamo le filimi ea pele e entsoeng ka letlapa.
     • Lihlahisoa tsa tlhokomelo ea botho: E sebetsa e le motenya le botsitso.
3. Methyl Hydroxyethyl Cellulose (MHEC):
   • Lisebelisoa:
     • Kaho: E matlafatsa ho bolokoa ha metsi le ho teteana ha metsoako ea seretse.
     • Liaparo: E ntlafatsa thepa ea rheological ka lipente le mekhoa e meng.
4. Carboxymethyl Cellulose (CMC):
   • Lisebelisoa:
     • Indasteri ea lijo: E sebelisoa e le ntho e tiisang le ho tsitsisa lihlahisoa tse fapaneng tsa lijo.
     • Meriana ea Meriana: E sebetsa e le tlamahano ho metsoako ea matlapa.
     • Lihlahisoa tsa tlhokomelo ea botho: E sebetsa e le motenya le botsitso.
5. Ethyl Cellulose (EC):
   • Lisebelisoa:
     • Meriana ea Meriana: E sebelisoa ka li-coatings bakeng sa litlolo tse laoloang.
     • Liaparo tse khethehileng le li-inks: O sebetsa joalo ka filimi ea pele.
6. Sodium Carboxymethyl Cellulose (NaCMC kapa SCMC):
   • Lisebelisoa:
     • Indasteri ea lijo: E sebelisoa e le seteifatsi le botsitso lihlahisoa tsa lijo.
     • Meriana ea Meriana: E sebetsa e le tlamahano ho metsoako ea matlapa.
     • Ho chekoa ha oli: E sebelisoa e le sets'oants'o sa maqhubu a metsi a chekang.
7. Hydroxypropylcellulose (HPC):
   • Lisebelisoa:
     • Li-Coatings: E sebetsa e le ntho e teteaneng le filimi ea pele ea li-coatings le li-inks.
     • Meriana ea Meriana: E sebelisoa e le se tlamang, se qhalaneng, le sa tokollo e laoloang.
8. Cellulose ea Microcrystalline (MCC):
   • Lisebelisoa:
     • Meriana ea Meriana: E sebelisoa e le tlamahano le ho senya metsoako ea matlapa.

Li-cellulose ethers tsena li fana ka mefuta e mengata ea mesebetsi e kang ho teteaneng, ho boloka metsi, ho thehoa ha lifilimi, le ho tsitsisa, ho etsa hore e be tsa bohlokoa liindastering tse kang kaho, meriana, lijo, tlhokomelo ea botho, le tse ling. Baetsi ba hlahisa li-cellulose ethers ka limaraka tse fapaneng ho fihlela litlhoko tse khethehileng tsa kopo.
