Yiziphi izinhlobo ze-Cellulose ether?

Ama-cellulose ether ayiqembu elihlukahlukene lama-polymer atholakala ku-cellulose, i-polysaccharide yemvelo etholakala ezitshalweni. Asetshenziswa kabanzi ezimbonini ezahlukahlukene, okuhlanganisa ezokwakha, ezemithi, ukudla, izimonyo, kanye nokunakekelwa komuntu siqu, ngenxa yezakhiwo zawo ezihlukile kanye nokuguquguquka kwazo. Nazi ezinye zezinhlobo ezivame kakhulu ze-cellulose ether:

1. I-Methyl Cellulose (MC):
   • I-Methyl cellulose ikhiqizwa ngokwelapha i-cellulose nge-methyl chloride ukuze kufakwe amaqembu e-methyl emgogodleni we-cellulose.
   • Iyancibilika emanzini abandayo futhi yakha izixazululo ezicacile neziqinile.
   • I-MC isetshenziswa njengesithambisi, isihlanganisi, kanye nesiqinisi ezinhlotsheni eziningi zezicelo, okuhlanganisa izinto zokwakha (isb., izingcezu ze-mortar ezisekelwe kusimende, ama-plaster asekelwe ku-gypsum), imikhiqizo yokudla, imithi, kanye nezinto zokunakekela umuntu siqu.
2. I-Hydroxyethyl Cellulose (HEC):
   • I-Hydroxyethyl cellulose yenziwa ngokuxuba i-cellulose ne-ethylene oxide ukuze kufakwe amaqembu e-hydroxyethyl emgogodleni we-cellulose.
   • Iyancibilika emanzini abandayo futhi yakha izixazululo ezicacile neziqinile ezinezakhiwo ezinhle kakhulu zokugcina amanzi.
   • I-HEC ivame ukusetshenziswa njengesithako sokujiya, ukulungisa i-rheology, kanye ne-ejenti yokwakha ifilimu kupende, izinto zokunamathisela, imikhiqizo yokunakekela umuntu siqu, kanye nemithi.
3. I-Hydroxypropyl Methyl Cellulose (HPMC):
   • I-hydroxypropyl methyl cellulose ikhiqizwa ngokungenisa amaqembu e-hydroxypropyl kanye ne-methyl kumgogodla we-cellulose.
   • Ibonisa izakhiwo ezifana ne-methyl cellulose kanye ne-hydroxyethyl cellulose, okuhlanganisa ukuncibilika kwamanzi, ikhono lokwenza ifilimu, kanye nokugcinwa kwamanzi.
   • I-HPMC isetshenziswa kabanzi ezintweni zokwakha (isb., izinamathiseli zethayela, izifanekiso ezisekelwe kusimende, izinto ezizilinganisayo), kanye nasemithini, emikhiqizweni yokudla, nasezintweni zokunakekela umuntu siqu.
4. I-Carboxymethyl Cellulose (CMC):
   • I-carboxymethyl cellulose itholakala ku-cellulose ngokuyelapha nge-sodium hydroxide kanye ne-monochloroacetic acid ukuze kwethulwe amaqembu e-carboxymethyl.
   • Iyancibilika emanzini futhi yakha izixazululo ezicacile, eziqinile ezinezakhiwo ezinhle kakhulu zokuqina, ukuzinza, kanye nokugcina amanzi.
   • I-CMC ivame ukusetshenziswa njengesithako sokujiya, isihlanganisi, kanye nesiguquli se-rheology emikhiqizweni yokudla, imithi, izindwangu, iphepha, kanye nezinye izinto zokwakha.
5. I-Ethyl Cellulose (EC):
   • I-ethyl cellulose ikhiqizwa ngokusabela kwe-cellulose ne-ethyl chloride ukuze kufakwe amaqembu e-ethyl emgogodleni we-cellulose.
   • Ayincibiliki emanzini kodwa incibilika ezinyibilikisini eziphilayo ezifana ne-ethanol ne-chloroform.
   • I-EC ivame ukusetshenziswa njenge-ejenti yokwakha ifilimu, i-binder, kanye nezinto zokumboza emithini yemithi, imikhiqizo yokudla, izimonyo, kanye nezicelo zezimboni.

Lezi ezinye zezinhlobo ezisetshenziswa kakhulu ze-cellulose ether, ngayinye inikeza izakhiwo nezinzuzo ezihlukile zezinhlelo zokusebenza ezahlukene. Amanye ama-cellulose ether akhethekile nawo angase abe khona, aklanyelwe izidingo ezithile ezimbonini ezahlukene.
