Izinhlobo ze-cellulose ether
Ama-cellulose ether ayiqembu elihlukahlukene lokuphuma kokunye okutholwe ngokushintsha amakhemikhali i-cellulose yemvelo, ingxenye eyinhloko yezindonga zamaseli ezitshalo. Uhlobo oluthile lwe-cellulose ether lunqunywa uhlobo lokuguqulwa kwamakhemikhali okwethulwa kumgogodla we-cellulose. Nazi ezinye izinhlobo ezivamile zama-cellulose ethers, ngayinye enezici zayo ezihlukile nezindlela zokusebenza:
- I-Methyl Cellulose (MC):
- Ukuguqulwa Kwamakhemikhali: Ukwethulwa kwamaqembu e-methyl kumgogodla we-cellulose.
- Izakhiwo Nezicelo:
- Ancibilikayo emanzini.
- Isetshenziswa ezintweni zokwakha (udaka, izinto zokunamathisela), imikhiqizo yokudla, kanye nemithi (ama-tablet coatings).
- I-Hydroxyethyl Cellulose (HEC):
- Ukuguqulwa Kwamakhemikhali: Ukwethulwa kwamaqembu e-hydroxyethyl kumgogodla we-cellulose.
- Izakhiwo Nezicelo:
- Incibilika kakhulu emanzini.
- Isetshenziswa kakhulu kuzimonyo, emikhiqizweni yokunakekelwa komuntu siqu, amapende, nasezikhemisi.
- I-Hydroxypropyl Methyl Cellulose (HPMC):
- Ukuguqulwa Kwamakhemikhali: Ukwethulwa kwamaqembu e-hydroxypropyl kanye ne-methyl kumgogodla we-cellulose.
- Izakhiwo Nezicelo:
- Ancibilikayo emanzini.
- Isetshenziswa kakhulu ezintweni zokwakha (udaka, okokugqoka), imithi, nemikhiqizo yokudla.
- I-Carboxymethyl Cellulose (CMC):
- Ukuguqulwa Kwamakhemikhali: Ukwethulwa kwamaqembu e-carboxymethyl kumgogodla we-cellulose.
- Izakhiwo Nezicelo:
- Ancibilikayo emanzini.
- Isetshenziswa njenge-thickener ne-stabilizer emikhiqizweni yokudla, imithi, izindwangu, kanye noketshezi lokumba.
- I-Hydroxypropyl Cellulose (HPC):
- Ukuguqulwa Kwamakhemikhali: Ukwethulwa kwamaqembu e-hydroxypropyl kumgogodla we-cellulose.
- Izakhiwo Nezicelo:
- Ancibilikayo emanzini.
- Isetshenziswa kakhulu emithini yemithi njenge-binder, i-ejenti yokwakha ifilimu, kanye ne-thickener.
- I-Ethyl Cellulose (EC):
- Ukuguqulwa Kwamakhemikhali: Ukwethulwa kwamaqembu e-ethyl kumgogodla we-cellulose.
- Izakhiwo Nezicelo:
- Amanzi angancibiliki.
- Isetshenziswa kuma-coatings, amafilimu, nasekwenziweni kwemithi ekhishwa okulawulwayo.
- I-Hydroxyethyl Methyl Cellulose (HEMC):
- Ukuguqulwa Kwamakhemikhali: Ukwethulwa kwamaqembu e-hydroxyethyl kanye ne-methyl kumgogodla we-cellulose.
- Izakhiwo Nezicelo:
- Ancibilikayo emanzini.
- Okuvame ukusetshenziswa ezintweni zokwakha (udaka, ama-grouts), amapende, nezimonyo.
Lezi zinhlobo zama-cellulose ethers zikhethwa ngokusekelwe ezimpahleni zazo ezithile kanye nokusebenza okudingekayo ekusetshenzisweni okuhlukahlukene. Ukuguqulwa kwamakhemikhali kunquma ukuncibilika, i-viscosity, nezinye izici zokusebenza ze-cellulose ether ngayinye, okuzenza izithasiselo eziguquguqukayo ezimbonini ezifana nezokwakha, ezemithi, ukudla, izimonyo, nokuningi.
