Li-ether tsa selulose

Li-ether tsa seluloseke lelapa la li-polymer tse qhibilihang metsing tse tsoang ho cellulose, e leng polymer ea tlhaho e fumanoang maboteng a sele ea limela. Li-derivative tsena li etsoa ka liphetoho tsa lik'hemik'hale tsa cellulose, e leng se fellang ka lihlahisoa tse fapaneng tse nang le thepa e fapaneng. Li-ether tsa cellulose li sebelisoa haholo liindastering tse fapaneng ka lebaka la ho tenyetseha ha tsona le mesebetsi ea tsona e ikhethang. Mona ke mefuta e meng e tloaelehileng ea li-ether tsa cellulose le ts'ebeliso ea tsona:

1. Selulose ea Hydroxyethyl (HEC):
   • Likopo:
     • Pente le masela: E sebetsa e le sesebelisoa sa ho teteana le ho fetola rheology.
     • Lihlahisoa tsa tlhokomelo ea botho: Li sebelisoa ka har'a li-shampoo, litlolo le litlolo tse lotionang e le sesebelisoa se tiisang le se tiisang letlalo.
     • Thepa ea kaho: E ntlafatsa ho boloka metsi le ho sebetsa habonolo ka har'a li-mortar le likhomaretsi.
2. Hydroxypropyl Methylcellulose (HPMC):
   • Likopo:
     • Kaho: E sebelisoa ka har'a li-mortar, likhomaretsi le li-coat bakeng sa ho ntlafatsa ts'ebetso le ho khomarela.
     • Meriana: E sebetsa e le sehokelo le filimi e entsoeng ka har'a metsoako ea matlapa.
     • Lihlahisoa tsa tlhokomelo ea botho: Li sebetsa e le setefatsi le se tiisang.
3. Selelulose ea Methyl Hydroxyethyl (MHEC):
   • Likopo:
     • Kaho: E ntlafatsa ho boloka metsi le ho teteana ha metsoako ea seretse.
     • Liaparo: Li ntlafatsa thepa ea rheological lipenteng le mefuteng e meng.
4. Selulose ea Carboxymethyl (CMC):
   • Likopo:
     • Indasteri ea lijo: E sebelisoa e le sesebelisoa sa ho tiisa le ho tiisa lihlahisoa tse fapaneng tsa lijo.
     • Meriana: E sebetsa e le setlama sa ho kopanya metsoako ea matlapa.
     • Lihlahisoa tsa tlhokomelo ea botho: Li sebetsa e le setefatsi le se tiisang.
5. Selulose ea Ethyl (EC):
   • Likopo:
     • Meriana: E sebelisoa ho koaheleng bakeng sa mekhoa e laoloang ea ho lokolla.
     • Likoahelo le enke tse khethehileng: E ​​sebetsa e le filimi ea pele.
6. Selulose ea Sodium Carboxymethyl (NaCMC kapa SCMC):
   • Likopo:
     • Indasteri ea lijo: E sebelisoa e le setefatsi le se tiisang lijong.
     • Meriana: E sebetsa e le setlama sa ho kopanya metsoako ea matlapa.
     • Ho cheka oli: E sebelisoa e le setlolo sa ho qhibilihisa maro a ho cheka.
7. Hydroxypropylcellulose (HPC):
   • Likopo:
     • Liaparo: Li sebetsa e le setenya le se etsang filimi ka har'a liaparo le enke.
     • Meriana: E sebelisoa e le ntho e kopanyang, e qhalang, le e laolang ho lokolla.
8. Selulose e nyenyane e kristale (MCC):
   • Likopo:
     • Meriana: E sebelisoa e le ntho e kopanyang le e qhalang matlapeng.

Li-ether tsena tsa cellulose li fana ka mesebetsi e mengata e kang ho teteana, ho boloka metsi, ho thehoa ha filimi le ho tsitsisa, e leng se etsang hore li be bohlokoa liindastering tse kang tsa kaho, meriana, lijo, tlhokomelo ea botho le tse ling. Bahlahisi ba hlahisa li-ether tsa cellulose ka mekhahlelo e fapaneng ho fihlela litlhoko tse itseng tsa ts'ebeliso.
