Yini i-cellulose ether

I-Cellulose Afers ingumndeni wamakhemikhali asuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. Lezi zinto zokutholwa zidalwe ngokuguqulwa kwamakhemikhali kwama-molecule we-cellulose ukwethula amaqembu ahlukahlukene asebenzayo, okuholela ezinhlobonhlobo ezahlukahlukene zezakhiwo nezinhlelo zokusebenza. Izimpikiswano zeCellulose zivame ukusetshenziswa ezimbonini ezinjengezokwakha, ezemithi, ukudla, izimonyo kanye nokunakekelwa komuntu siqu ngenxa yemvelo yazo eguquguqukayo nezakhiwo ezizuzisayo. Nazi ezinye izinhlobo ezijwayelekile ze-cellulose kanye nokusetshenziswa kwazo:

1. Methyl cellulose (MC):
   • I-methyl cellulose ikhiqizwa ngokwelapha iselula nge-methyl chloride.
   • Kuyancibilika emanzini nokwenza amafomu acacile, ama-viscous solutions.
   • I-MC isetshenziswa njengesikhudlwana, i-Binder, neStabilizer ezintweni zokwakha (isib. Uhlobo lomuntu osuselwa kuso usimende, ama-plasters asuselwa ku-gypsum), imikhiqizo yokudla, nemithi yemithi kanye nezinto zokunakekelwa komuntu.
2. I-Hydroxyyethyl cellulose (HEC):
   • I-Hydroxyyethyl celtulose ihlelwe ngokuphendula i-cellulose nge-ethylene oxide ukwethula amaqembu we-hydroxyethyl.
   • Kuyancibilika emanzini nokwakha amafomu acacile, izisombululo ezibonakalayo ezinezakhiwo 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.

Lezi ngezinye zezithambekela ezisetshenziswa kakhulu ze-cellulose, ngalinye linezakhiwo ezihlukile nezinhlelo zokusebenza ezimbonini ezahlukahlukene. Okunye okukhethekile kwe-cellulose izithathi kungahle kube khona, kuqondiswe kwizidingo ezithile ezisetshenzisweni ezahlukahlukene.
