Li-ether tse ntle ka ho fetisisa tsa Cellulose

Li-ether tsa cellulose ke lelapa la li-polymer tse qhibilihang ka metsing tse tsoang ho cellulose, e leng polymer ea tlhaho e fumanoang maboteng a sele ea limela. Li-derivative tsena ke li-polymer tsa cellulose tse fetotsoeng ka lik'hemik'hale tse nang le lihlopha tse fapaneng tsa ts'ebetso, tse fanang ka thepa e itseng ho limolek'hule. Li-ether tsa cellulose li sebelisoa haholo liindastering tse fapaneng ka lebaka la ho tenyetseha ha tsona, ho kenyeletsoa kaho, meriana, lijo, litlolo le tse ling.

Ho fumana ether ea cellulose e "molemo ka ho fetisisa" ho latela litlhoko tse ikhethileng tsa ts'ebeliso e reriloeng. Li-ether tse fapaneng tsa cellulose li bontša thepa e fapaneng, joalo ka viscosity, ho qhibiliha, le bokhoni ba ho etsa filimi, e leng se etsang hore li lokele merero e fapaneng. Mona ke tse ling tsa li-ether tsa cellulose tse sebelisoang haholo le tse nkoang hantle:

  1. Selelulose ea Methyl (MC):
    • Matlotlo: MC e tsebahala ka bokgoni ba yona bo phahameng ba ho boloka metsi, e leng se etsang hore e lokele ho sebediswa ditshebedisong tsa ho teteana, haholoholo indastering ya kaho. E boetse e sebediswa meriana le dihlahiswa tsa dijo.
    • Ditshebediso: Metswako ya seretse le samente, matlapa a meriana, le e le moemedi wa ho teteana dihlahisweng tsa dijo.
  2. Selulose ea Hydroxyethyl (HEC):
    • Matlotlo: HEC e fana ka ho qhibiliha ho hotle ha metsi mme e na le bokgoni ba ho laola ho teteana ha metsi. Hangata e sebediswa dihlahisweng tsa indasteri le tsa bareki.
    • Lisebelisoa: Pente le lipente, lihlahisoa tsa tlhokomelo ea botho (li-shampoo, li-lotion), likhomaretsi le metsoako ea meriana.
  3. Selulose ea Carboxymethyl (CMC):
    • Matlotlo: CMC e qhibiliha metsing 'me e na le matlotlo a matle a ho tenya le ho tsitsisa. E sebelisoa haholo indastering ea lijo le ea meriana.
    • Ditshebediso: Dihlahiswa tsa dijo (jwalo ka setefatsi le se tsitsisang), meriana, ditlolo, masela le maro a ho tjheka indastering ya oli le kgase.
  4. Hydroxypropyl Methyl Cellulose (HPMC):
    • Matlotlo: HPMC e fana ka tekano e ntle ea ho qhibiliha ha metsi, ho kenngoa ha mocheso le thepa ea ho etsa filimi. E sebelisoa haholo lits'ebetsong tsa kaho le tsa meriana.
    • Ditshebediso: Dikhomaretsi tsa thaele, di-render tse thehilweng ho samente, di-formulations tsa meriana tse nowang, le ditsamaiso tsa ho tlisa meriana e ntshang ka taolo.
  5. Selulose ea Ethyl Hydroxyethyl (EHEC):
    • Matlotlo: EHEC e tsebahala ka ho teteana ha eona le ho boloka metsi, e leng se etsang hore e lokele ho sebelisoa ka thata kahong le meriana.
    • Ditshebediso: Di-additives tsa seretse, dintho tse teteanang meriana le ditlolo.
  6. Selulose ea Sodium Carboxymethyl (Na-CMC):
    • Matlotlo: Na-CMC ke ether ea cellulose e qhibilihang ka metsing e nang le makgetha a matle a ho tenya le ho tsitsisa. E atisa ho sebelisoa lijong le lits'ebetsong tse fapaneng tsa indasteri.
    • Ditshebediso: Dihlahiswa tsa dijo (jwalo ka setefatsi le se tsitsisang), meriana, masela le maro a ho tjheka.
  7. Selulose e nyenyane e kristale (MCC):
    • Matlotlo: MCC e na le dikarolwana tse nyane, tse kang kristale mme e sebediswa hangata e le setlatsetsi le se tlatsang matlapeng a meriana.
    • Lisebelisoa: Matlapa a meriana le li-capsule.
  8. Setache sa Sodium Carboxymethyl (CMS):
    • Matlotlo: CMS ke setlolo se tswang ho starch se nang le matlotlo a tshwanang le Na-CMC. E sebediswa haholo indastering ya dijo.
    • Ditshebediso: Dihlahiswa tsa dijo (jwalo ka setefatsi le se tsitsisang), masela le meriana.

Ha o kgetha ether ya cellulose bakeng sa tshebediso e itseng, ho bohlokwa ho nahana ka dintlha tse kang ho qhibilihisa ho hlokahalang, ho qhibiliha, botsitso, le dibopeho tse ding tsa tshebetso. Ho feta moo, ho latela maemo a taolo le dintho tse lokelang ho elwa hloko tikolohong ho lokela ho elwa hloko. Bahlahisi hangata ba fana ka maqephe a data a tekheniki ka tlhahisoleseding e qaqileng mabapi le thepa le tshebediso e kgothalletswang ya ether e itseng ya cellulose.
