Iimpawu eziphambili ze-carboxymethyl cellulose sodium CMC.

I-Sodium carboxymethylcellulose (CMC) yipolymer eguquguqukayo neguquguqukayo enezicelo ezininzi kumashishini ahlukeneyo. Le khompawundi ivela kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zesityalo. I-CMC iveliswa ngokuguqula iikhemikhali zeselulosi ngokwazisa amaqela e-carboxymethyl kumqolo we-cellulose. Isiphumo se-sodium carboxymethylcellulose sineempawu ezizodwa ezenza ukuba zixabiseke kwizicelo ezininzi.

Ulwakhiwo lweMolekyuli:

Isakhiwo semolekyuli ye-sodium carboxymethylcellulose iqukethe i-cellulose backbone kunye namaqela e-carboxymethyl (-CH2-COO-Na) exhunywe kumaqela athile e-hydroxyl kwiiyunithi ze-glucose. Olu hlengahlengiso lunika ukunyibilika kunye nezinye iipropathi eziluncedo kwipolymer yeselulosi.

Ukunyibilika kunye neempawu zesisombululo:

Enye yezinto eziphambili zeCMC kukunyibilika kwayo emanzini. I-sodium carboxymethyl cellulose inyibilika ngokulula emanzini kwaye yenza isisombululo se-viscous esicacileyo. I-Solubility inokulungelelaniswa ngokutshintsha i-degree of substitution (DS), eyi-avareji yenani lamaqela e-carboxymethyl kwiyunithi ye-glucose kwikhonkco le-cellulose.

Iimpawu zeRheological:

Ukuziphatha kwe-rheological yezisombululo ze-CMC kuyaphawuleka. I-viscosity yezisombululo ze-CMC iyanda ngokugxila okukhulayo kwaye kuxhomekeke ngamandla kwiqondo lokuthatha indawo. Oku kwenza i-CMC ibe sisityebi esisebenzayo kwizicelo ezahlukeneyo, kubandakanya ukutya, amayeza kunye neenkqubo zoshishino.

Iimpawu ze-Ionic:

Ubukho beeyoni zesodium kumaqela e-carboxymethyl kunika i-CMC isimilo sayo se-ionic. Ubume be-ionic buvumela i-CMC ukusebenzisana nezinye iintlobo ezihlawuliswayo kwisisombululo, iyenza ibe luncedo kwizicelo ezifuna ukubopha okanye ukwakhiwa kwejeli.

Ubuzaza be-pH:

Ukunyibilika kunye neepropati ze-CMC zichatshazelwa yi-pH. I-CMC inonyibiliko oluphezulu kwaye ibonisa ukusebenza kwayo kakuhle phantsi kweemeko zealkaline kancinane. Nangona kunjalo, ihlala izinzile kuluhlu olubanzi lwe-pH, ibonelela ngokuguquguquka kwezicelo ezahlukeneyo.

Iimpawu zokwenza ifilimu:

I-sodium carboxymethylcellulose inamandla okwenza ifilimu, okwenza ukuba ifaneleke kwizicelo ezifuna ukubunjwa kweefilimu ezincinci okanye iingubo. Le propati ingasetyenziselwa ukuvelisa iifilimu ezidliwayo, iingubo zethebhulethi, njl.

Zinzisa:

I-CMC izinzile phantsi kweemeko ezahlukeneyo zokusingqongileyo, kubandakanywa ubushushu kunye nokutshintsha kwe-pH. Olu zinzo lunegalelo kubomi balo beshelufu ende kunye nokufaneleka koluhlu olubanzi lwezicelo.

I-Emulsion stabilizer:

I-CMC isebenza njenge-emulsifier esebenzayo kwaye inceda ukuzinzisa i-emulsions ekutyeni kunye ne-cosmetic formulations. Iphucula ukuzinza kwe-oli-in-water emulsions, inceda ukuphucula umgangatho jikelele kunye nobomi beshelufu yemveliso.

Ugcino lwamanzi:

Ngenxa yokukwazi ukufunxa amanzi, iCMC isetyenziswa njenge arhente yokugcina amanzi kumashishini ahlukeneyo. Le propati inenzuzo kakhulu kwizicelo ezifana neempahla, apho i-CMC inceda ukugcina ukufuma kwamalaphu ngexesha leenkqubo ezahlukeneyo.

Ukonakala kwezinto eziphilayo:

I-sodium carboxymethylcellulose ithathwa njenge-biodegradable kuba iphuma kwi-cellulose, i-polymer eyenzeka ngokwemvelo. Olu phawu lunobuhlobo kakhulu nokusingqongileyo kwaye luhambelana nemfuno ekhulayo yezinto ezizinzileyo kuwo wonke amashishini.
