Ziziphi iintlobo zeCellulose ether?

I-cellulose ethers liqela elihlukeneyo leepolymers ezivela kwi-cellulose, i-polysaccharide yendalo efumaneka kwizityalo. Zisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya ukwakhiwa, amayeza, ukutya, izithambiso, kunye nokhathalelo lomntu, ngenxa yeempawu zabo ezizodwa kunye nokuguquguquka. Nazi ezinye zezona ntlobo zixhaphakileyo ze-cellulose ether:

1. I-Methyl Cellulose (MC):
   • I-Methyl cellulose iveliswa ngokunyanga i-cellulose nge-methyl chloride ukwazisa amaqela e-methyl kwi-cellulose backbone.
   • Iyanyibilika kumanzi abandayo kwaye yenza izisombululo ezicacileyo, ezibonakalayo.
   • I-MC isetyenziswa njenge-thickener, i-binder, kunye ne-stabilizer kuluhlu olubanzi lwezicelo, kubandakanywa izinto zokwakha (umzekelo, ii-samente-based mortars, i-plasters esekelwe kwi-gypsum), iimveliso zokutya, amayeza, kunye nezinto zokukhathalela umntu.
2. I-Hydroxyethyl Cellulose (HEC):
   • I-Hydroxyethyl cellulose yenziwa ngokusabela i-cellulose nge-ethylene oxide ukwazisa amaqela e-hydroxyethyl kumqolo we-cellulose.
   • Iyanyibilika kumanzi abandayo kwaye yenza izisombululo ezicacileyo, ezibonakalayo ezineempawu ezintle zokugcina amanzi.
   • I-HEC isetyenziswa ngokuqhelekileyo njenge-thickener, i-rheology modifier, kunye ne-agent-forming agent kwiipende, i-adhesives, imveliso yokunyamekela komntu, kunye namayeza.
3. I-Hydroxypropyl Methyl Cellulose (HPMC):
   • I-Hydroxypropyl methyl cellulose iveliswa ngokwazisa i-hydroxypropyl kunye namaqela e-methyl kwi-cellulose backbone.
   • Ibonisa iipropati ezifanayo zombini i-methyl cellulose kunye ne-hydroxyethyl cellulose, kuquka ukunyibilika kwamanzi, amandla okwenza ifilimu, kunye nokugcinwa kwamanzi.
   • I-HPMC isetyenziswa kakhulu kwizinto zokwakha (umzekelo, izinto zokuncamathelisa iithayile, unikezelo olusekwe kwisamente, iikhompawundi zokuzilinganisa), kunye namayeza, iimveliso zokutya, kunye nezinto zokhathalelo lomntu.
4. I-Carboxymethyl Cellulose (CMC):
   • I-Carboxymethyl cellulose ithathwe kwi-cellulose ngokuyiphatha nge-sodium hydroxide kunye ne-monochloroacetic acid ukwazisa amaqela e-carboxymethyl.
   • Iyanyibilika emanzini kwaye yenza izisombululo ezicacileyo, ezine-viscous ezinokuqina okugqwesileyo, ukuzinzisa, kunye neempawu zokugcina amanzi.
   • I-CMC iqhele ukusetyenziswa njenge-thickener, binder, kunye ne-rheology modifier kwiimveliso zokutya, amayeza, amalaphu, iphepha, kunye nezinye izinto zokwakha.
5. I-Ethyl Cellulose (EC):
   • I-Ethyl cellulose iveliswa ngokusabela i-cellulose nge-ethyl chloride ukwazisa amaqela e-ethyl kwi-cellulose backbone.
   • Ayinyibiliki emanzini kodwa inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye nekloroform.
   • I-EC iqhele ukusetyenziswa njenge-ejenti yokwenza ifilimu, i-binder, kunye nezinto zokugquma kumayeza, iimveliso zokutya, izithambiso, kunye nokusetyenziswa kwemizi-mveliso.

Ezi zezinye zezona ntlobo zixhaphakileyo ze-cellulose ether, nganye inika iipropati ezizodwa kunye neenzuzo zezicelo ezahlukeneyo. Ezinye ii-ether ze-cellulose ezikhethekileyo zisenokubakho, zilungiselelwe iimfuno ezithile kumashishini ahlukeneyo.
