Yiziphi izinhlobo ze-cellulose ether?

I-Cellulose TETERS iyiqembu elihlukahlukene lama-polymers asuselwa ku-cellulose, i-polysaccharide etholakala ezitshalweni. Zisetshenziswa kabanzi kwizimboni ezahlukahlukene, kufaka phakathi ukwakhiwa, amakhamishini, ukudla, izimonyo, kanye nokunakekelwa komuntu siqu, ngenxa yezakhiwo zazo ezihlukile nokusebenza okuhlukahlukene. Nazi ezinye izinhlobo ezivame kakhulu ze-cellulose ether:

1. Methyl cellulose (MC):
   • I-methyl cellulose ikhiqizwa ngokwelapha i-cellulose nge-methyl chloride ukwethula amaqembu we-methyl emhlane we-cellulose.
   • Kuyancibilika emanzini abandayo kanye nokwenza amafomu acacile, ama-viscous solutions.
   • I-MC isetshenziswa njengesikhudlwana, i-Binder, neStabilizer ezinhlangeni ezahlukahlukene, kufaka phakathi izinto zokwakha (isib. Uhlobo lomuntu osuselwa ku-cyment, ama-gypsum asuselwa ku-gypShers), imikhiqizo yokudla, kanye nezinto zokudla kanye nezinto zokunakekelwa komuntu.
2. I-Hydroxyyethyl cellulose (HEC):
   • I-Hydroxyyethyl celtulose ihlelwe ngokuphendula i-cellulose nge-ethylene oxide ukwethula amaqembu we-hydroxyethyl e-celluloose backbone.
   • Kuyancibilika emanzini abandayo kanye nokwenza amafomu acacile, ama-viscous solutions anezakhiwo ezinhle kakhulu zokugcina amanzi.
   • I-HEC isetshenziswa kakhulu njengoMkhulu, i-Rheology Modifier, kanye ne-ejenti eyakha amafilimu ku-Paints, anamathela, imikhiqizo yokunakekelwa komuntu siqu, kanye nemithi yezemithi.
3. I-Hydroxypropyl methyl cellulose (HPMC):
   • I-Hydroxypropylllylylylylyllllulose ikhiqizwa ukwethula ama-hydroxypropyl kanye namaqembu we-methyl emhlane.
   • Ibonisa izakhiwo ezifana ne-methyl cellulose ne-hydroxyyethyl cellulose, kufaka phakathi i-solubity yamanzi, amandla okwenza amafilimu, nokugcinwa kwamanzi.
   • I-HPMC isetshenziswa kabanzi ezintweni zokwakha (isib. Ukunamathela okunamathayi, ama-rend-esekwe okolweni, amakhompiyutha okuzenzela), kanye nasemikhakheni yemithi, imikhiqizo yokudla, kanye nezinto zokudla komuntu siqu.
4. I-Carboxymethyl Cellulose (CMC):
   • I-Carboxymethyl Cellulose isuselwa ku-cellulose ngokuyiphatha ngeSodium Hydroxide ne-monochlororocetic acid ukwethula amaqembu e-carboxymethyl.
   • Kuyancibilika emanzini nokwakha amafomu acacile, ama-viscous solutions aqiniswe amahle, aqiniswe, kanye nezakhiwo zokugcina amanzi.
   • I-CMC isetshenziswa kakhulu njenge-swerener, i-Binder, kanye ne-Rheology Modifier emikhiqizweni yokudla, imithi yemithi, izindwangu, ephepheni, nezinto zokwakha.
5. I-Ethyl Cellulose (EC):
   • I-ethyl cellulose ikhiqizwa ngokuphendula i-cellulose nge-ethyl chloride ukwethula amaqembu e-ethyl emhlane we-cellulose.
   • Kuyakhubazeka emanzini kepha kuncibilika ku-organic solvents njenge-ethanol ne-chloroform.
   • I-EC isetshenziswa kakhulu njenge-ejenti eyakha amafilimu, i-binder, kanye ne-coation impahla kuma-pharmaceuticals, imikhiqizo yokudla, izimonyo kanye nezicelo zezimboni.

Lezi ezinye zezinhlobo ezisetshenziswa kakhulu ze-cellulose ether, ngayinye enikeza izakhiwo ezihlukile nezinzuzo zezicelo ezihlukile. Okunye okukhethekile kwe-cellulose izithathi kungenzeka futhi kube khona, okuhambisana nezidingo ezithile ezimbonini ezahlukahlukene.
