Iindidi ze-cellulose ether

Iindidi ze-cellulose ether

I-cellulose ethers liqela elihlukeneyo lee-derivatives ezifunyenwe ngokuguqulwa kweekhemikhali ze-cellulose yendalo, eyona nto iphambili kwiindonga zeeseli zesityalo. Uhlobo oluthile lwe-cellulose ether luchongwa bubume bokuguqulwa kweekhemikhali ezifakwe kwi-cellulose backbone. Nazi ezinye iindidi eziqhelekileyo ze-cellulose ethers, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa:

  1. I-Methyl Cellulose (MC):
    • Ukuguqulwa kweMichiza: Ukuqaliswa kwamaqela e-methyl kumqolo we-cellulose.
    • Iipropati kunye nezicelo:
      • Ukunyibilika emanzini.
      • Isetyenziswe kwizinto zokwakha (udaka, i-adhesives), iimveliso zokutya, kunye namayeza (i-tablet coatings).
  2. I-Hydroxyethyl Cellulose (HEC):
    • Ukuguqulwa kweMichiza: Ukuqaliswa kwamaqela e-hydroxyethyl kumqolo we-cellulose.
    • Iipropati kunye nezicelo:
      • Ukunyibilika kakhulu emanzini.
      • Isetyenziswa ngokuqhelekileyo kwizinto zokuthambisa, iimveliso zokhathalelo lomntu, iipeyinti, kunye namayeza.
  3. I-Hydroxypropyl Methyl Cellulose (HPMC):
    • Ukuguqulwa kweMichiza: Ukuqaliswa kwe-hydroxypropyl kunye namaqela e-methyl kumqolo we-cellulose.
    • Iipropati kunye nezicelo:
      • Ukunyibilika emanzini.
      • Isetyenziswa kakhulu kwizinto zokwakha (udaka, iingubo), amayeza, kunye neemveliso zokutya.
  4. I-Carboxymethyl Cellulose (CMC):
    • Ukuguqulwa kweMichiza: Ukuqaliswa kwamaqela e-carboxymethyl kwi-cellulose backbone.
    • Iipropati kunye nezicelo:
      • Ukunyibilika emanzini.
      • Isetyenziswa njenge-thickener kunye ne-stabilizer kwiimveliso zokutya, amayeza, amalaphu, kunye nolwelo lokomba.
  5. ISelulosi yeHydroxypropyl (HPC):
    • Ukuguqulwa kwamachiza: Ukuqaliswa kwamaqela e-hydroxypropyl kumqolo we-cellulose.
    • Iipropati kunye nezicelo:
      • Ukunyibilika emanzini.
      • Ngokuqhelekileyo isetyenziswa kumayeza njenge-binder, i-agent eyenza ifilimu, kunye ne-thickener.
  6. I-Ethyl Cellulose (EC):
    • Ukuguqulwa kweMichiza: Ukuqaliswa kwamaqela e-ethyl kwi-cellulose backbone.
    • Iipropati kunye nezicelo:
      • Amanzi anganyibilikiyo.
      • Isetyenziswa kwiingubo zokwaleka, iifilimu, kunye nokulawulwa kokukhutshwa kwamayeza.
  7. I-Hydroxyethyl Methyl Cellulose (HEMC):
    • Ukuguqulwa kwamachiza: Ukuqaliswa kwe-hydroxyethyl kunye namaqela e-methyl kumqolo we-cellulose.
    • Iipropati kunye nezicelo:
      • Ukunyibilika emanzini.
      • Ngokuqhelekileyo zisetyenziswa kwizinto zokwakha (udaka, i-grouts), iipeyinti, kunye nezinto zokuthambisa.

Ezi ntlobo ze-cellulose ethers zikhethwa ngokusekelwe kwiipropati zabo ezithile kunye nokusebenza okufunekayo kwizicelo ezahlukeneyo. Ukuguqulwa kweekhemikhali kumisela ukunyibilika, i-viscosity, kunye nezinye iimpawu zokusebenza kwe-ether yeselulosi nganye, izenza izongezo eziguquguqukayo kumashishini afana nokwakha, amayeza, ukutya, izithambiso, kunye nokunye.
