Uvakalelo lwe-pH:

Ukunyibilika kunye neempawu zeCMC zichaphazeleka yi-pH. I-CMC inobunyibiliko obuphezulu kwaye ibonisa ukusebenza kwayo okuhle phantsi kweemeko ze-alkaline kancinci. Nangona kunjalo, ihlala izinzile kuluhlu olubanzi lwe-pH, inika ukuguquguquka kwiindlela ezahlukeneyo zokusetyenziswa.

Iimpawu zokwenza ifilimu:

I-sodium carboxymethylcellulose inamandla okwenza ifilimu, nto leyo eyenza ifaneleke kwiimfuno ezifuna ukwenziwa kweefilimu ezincinci okanye iingubo. Le propati ingasetyenziselwa ukuvelisa iifilimu ezityiwayo, iipilisi, njl.njl.

Zinzisa:

I-CMC izinzile phantsi kweemeko ezahlukeneyo zendalo, kuquka utshintsho lobushushu kunye ne-pH. Olu zinzo lunegalelo ekubeni ihlale ixesha elide kwaye ifaneleke kwiintlobo ngeentlobo zezicelo.

Isiqinisi se-emulsion:

I-CMC isebenza njenge-emulsifier esebenzayo kwaye inceda ukuzinzisa ii-emulsions ekutyeni nakwizinto zokuhombisa. Iphucula uzinzo lwee-emulsions zeoyile emanzini, inceda ukuphucula umgangatho kunye nobomi beshelufu bemveliso.

Ukugcinwa kwamanzi:

Ngenxa yokukwazi kwayo ukufunxa amanzi, i-CMC isetyenziswa njengearhente yokugcina amanzi kumashishini ahlukeneyo. Le propati iluncedo kakhulu kwizicelo ezifana neempahla, apho i-CMC inceda ukugcina umswakama kwimpahla ngexesha leenkqubo ezahlukeneyo.

Ukubola kwezinto eziphilayo:

I-sodium carboxymethylcellulose ithathwa njengenokubola kuba ivela kwi-cellulose, i-polymer yendalo. Olu phawu lunobuhlobo kakhulu nokusingqongileyo kwaye luhambelana nemfuno ekhulayo yezinto ezizinzileyo kumashishini onke.
