Yiziphi izinhlobo ze-Cellulose ether?

I-cellulose ethers iyiqembu elihlukahlukene lama-polymers atholakala ku-cellulose, i-polysaccharide yemvelo etholakala ezitshalweni.Zisetshenziswa kakhulu ezimbonini ezahlukahlukene, kufaka phakathi ezokwakha, ezemithi, ukudla, izimonyo, nokunakekelwa komuntu siqu, ngenxa yezakhiwo zazo ezihlukile kanye nokuhlukahluka.Nazi ezinye zezinhlobo ezivame kakhulu ze-cellulose ether:

1. I-Methyl Cellulose (MC):
   • I-Methyl cellulose ikhiqizwa ngokwelapha i-cellulose nge-methyl chloride ukwethula amaqembu e-methyl kumgogodla we-cellulose.
   • Iyancibilika emanzini abandayo futhi yakha izixazululo ezicacile, ezibukekayo.
   • I-MC isetshenziswa njenge-thickener, binder, kanye nesiqinisi ezinhlelweni eziningi zokusebenza, okuhlanganisa izinto zokwakha (isb., udaka olusekelwe kusimende, ukhonkolo olusekelwe ku-gypsum), imikhiqizo yokudla, imithi, nezinto zokunakekela umuntu.
2. I-Hydroxyethyl Cellulose (HEC):
   • I-Hydroxyethyl cellulose ihlanganiswa ngokuphendula i-cellulose ne-ethylene oxide ukwethula amaqembu e-hydroxyethyl kumgogodla we-cellulose.
   • Incibilika emanzini abandayo futhi yakha izixazululo ezicacile, ezine-viscous ezinezakhiwo ezinhle kakhulu zokugcina amanzi.
   • I-HEC ivame ukusetshenziswa njenge-thickener, i-rheology modifier, kanye ne-ejenti eyenza ifilimu kumapende, izinto zokunamathisela, imikhiqizo yokunakekelwa komuntu siqu, kanye nemithi.
3. IHydroxypropyl Methyl Cellulose (HPMC):
   • I-Hydroxypropyl methyl cellulose ikhiqizwa ngokwethula i-hydroxypropyl namaqembu e-methyl kumgogodla we-cellulose.
   • Ibonisa izakhiwo ezifanayo kokubili i-methyl cellulose ne-hydroxyethyl cellulose, okuhlanganisa ukuncibilika kwamanzi, ikhono lokwenza ifilimu, nokugcinwa kwamanzi.
   • I-HPMC isetshenziswa kakhulu ezintweni zokwakha (isb., izinto zokunamathisela zamathayela, ama-renders asekelwe kusimende, izinhlanganisela ezizilinganisa), kanye nasezikhemisi, emikhiqizweni yokudla, nasezintweni zokunakekela komuntu siqu.
4. I-Carboxymethyl Cellulose (CMC):
   • I-Carboxymethyl cellulose itholakala ku-cellulose ngokuyelapha nge-sodium hydroxide ne-monochloroacetic acid ukwethula amaqembu e-carboxymethyl.
   • Iyancibilika emanzini futhi yakha izixazululo ezicacile, ezine-viscous ezinokuqina okuhle kakhulu, ukuzinza, kanye nezindawo zokugcina amanzi.
   • I-CMC ivamise ukusetshenziswa njenge-thickener, binder, kanye ne-rheology modifier emikhiqizweni yokudla, imithi, izindwangu, iphepha, nezinye izinto zokwakha.
5. I-Ethyl Cellulose (EC):
   • I-Ethyl cellulose ikhiqizwa ngokuphendula i-cellulose ne-ethyl chloride ukwethula amaqembu e-ethyl kumgogodla we-cellulose.
   • Ayincibiliki emanzini kodwa iyancibilika kuzincibilikisi zemvelo ezifana ne-ethanol ne-chloroform.
   • I-EC ivamise ukusetshenziswa njenge-ejenti yokwakha ifilimu, i-binder, kanye nezinto zokumboza kwezemithi, emikhiqizweni yokudla, kwezimonyo nasezimbonini.

Lezi ezinye zezinhlobo ezivame ukusetshenziswa kakhulu ze-cellulose ether, ngayinye inikezela ngezakhiwo ezihlukile kanye nezinzuzo zezinhlelo zokusebenza ezahlukene.Amanye ama-cellulose ether akhethekile angase abe khona, enzelwe izidingo ezithile ezimbonini ezihlukahlukene.
