Izakhiwo zayo zifana ne-methyl cellulose, kodwa ngenxa yokuba khona kwe-hydroxyethyl cellulose, kulula ukuyincibilikisa emanzini, isixazululo sihambisana kakhulu nosawoti, futhi sinezinga lokushisa eliphakeme lokujiya.
03. I-Carboxymethyl cellulose
1. Kusetshenziswa ekubhobheni uwoyela negesi yemvelo, ekumbeni imithombo kanye neminye imisebenzi
① Udaka oluqukethe i-CMC lungenza udonga lomthombo lube yikhekhe lokuhlunga elincane neliqinile elinokungena okuncane kwamanzi, okunciphisa ukulahleka kwamanzi.
② Ngemva kokufaka i-CMC odakeni, umshini wokubhoboza ungathola amandla amancane okuqala okusika, ukuze udaka lukwazi ukukhulula kalula igesi egoqwe kuwo, futhi ngesikhathi esifanayo, udoti ungalahlwa ngokushesha emgodini wodaka.
③ Udaka lokubhoboza, njengezinye izinto ezilengayo kanye nezihlakazekile, lunesikhathi esithile sokuhlala eshalofini. Ukwengeza i-CMC kungayenza iqine futhi kwandise isikhathi sokuhlala eshalofini.
④ Udaka oluqukethe i-CMC aluvamile ukuthintwa yisikhunta, ngakho-ke kumele lugcine inani le-pH ephezulu, futhi akudingekile ukusebenzisa izilondolozi.
⑤ Iqukethe i-CMC njenge-ejenti yokwelapha ukubhoboza uketshezi lokuhlanza udaka, olungamelana nokungcola kosawoti ohlukahlukene oncibilikayo.
⑥ Udaka oluqukethe i-CMC luzinzile futhi lunganciphisa ukulahleka kwamanzi noma ngabe izinga lokushisa lingaphezu kuka-150°C.
I-CMC enobuthi obukhulu kanye nezinga eliphezulu lokushintshana ifanele udaka olunobuthi obuphansi, kanti i-CMC enobuthi obuphansi kanye nezinga eliphezulu lokushintshana ifanele udaka olunobuthi obukhulu. Ukukhetha i-CMC kufanele kunqunywe ngokwezimo ezahlukene njengohlobo lodaka, indawo, kanye nokujula komthombo.
