Astaamaha Sodium Carboxymethyl Cellulose

Sodium carboxymethyl cellulose (CMC) waa biyo-milmi kara, polymer anionic oo ka soo jeeda cellulose. Waxaa soo saaray falcelinta cellulose leh chloroacetic acid iyo sodium hydroxide. CMC waxay leedahay hanti badan oo kala duwan oo ka dhigaysa mid faa'iido u leh codsiyada warshadaha kala duwan. Waa kuwan qaar ka mid ah sifooyinka muhiimka ah ee CMC:

1. Solubility: CMC aad bay ugu milmayaan biyaha, taas oo sahlaysa in wax laga qabto loona isticmaalo codsiyo kala duwan. Waxa kale oo ay ku milmi kartaa qaar ka mid ah dareerayaasha organic, sida ethanol iyo glycerol, taas oo ku xidhan heerka beddelka.
2. Viscosity: CMC waa polymer viscous ah oo aad u sarreeya kaas oo samayn kara jel si aad u sarreeya. Viscosity ee CMC waxaa saameeya arrimo kala duwan, sida heerka beddelka, fiirsashada, pH, heerkulka, iyo diiradda electrolyte.
3. Rheology: CMC waxa ay muujisaa hab-dhaqanka pseudoplastic, taas oo macnaheedu yahay in maw-jiidkiisu hoos u dhaco iyada oo la kordhinayo heerka xiiridda. Hantidani waxay faa'iido u leedahay codsiyada halka loo baahan yahay viscosity sare inta lagu jiro farsamaynta, laakiin viscosity hoose ayaa loo baahan yahay inta lagu jiro codsiga.
4. Guryaha samaynta filimada: CMC waxay samayn kartaa filimo khafiif ah, dabacsan marka la qalajiyo. Filimadani waxay leeyihiin sifooyin xannibaad oo wanaagsan waxaana loo isticmaali karaa dahaadh ahaan codsiyo kala duwan.
5. Xasilooni: CMC waa ku xasiloon tahay pH ballaaran iyo xaaladaha heerkulka. Waxa kale oo ay adkaysi u leedahay xaalufka microbial, taas oo ka dhigaysa mid ku habboon isticmaalka cuntada iyo codsiyada daawooyinka.
6. Haysashada biyaha: CMC waxay awood u leedahay inay nuugo oo ay hayso biyaha, taas oo ka dhigaysa mid waxtar u leh codsiyada meelaha ay biyuhu muhiim u yihiin, sida alaabta daryeelka shakhsi ahaaneed, daawooyinka, iyo alaabta cuntada.
7. Xasilinta Emulsion: CMC waxaa loo isticmaali karaa in lagu dejiyo emulsions, taas oo muhiim u ah soo saarista alaabooyin kala duwan, sida rinji, dhejisyo, iyo dahaarka.
8. Adhesion: CMC waxay wanaajin kartaa ku dheggan ee codsiyada kala duwan, sida dahaarka, rinjiga, iyo xabagta.
9. Guryaha hakinta: CMC waxa ay wanaajin kartaa sifooyinka ganaaxa ee alaabada kala duwan, sida joojinta midabada, macdanta, iyo qaybaha kale.

Gebogebadii, Sodium Carboxymethyl Cellulose (CMC) waa polymer aad u isku dhafan oo soo bandhigaya noocyo kala duwan oo hanti ah, oo ay ku jiraan milanka, viscosity, rheology, xasiloonida, guryaha samaynta filimada, haynta biyaha, xasilinta emulsion, adhesion, iyo guryaha joojinta. Guryahani waxay ka dhigaan CMC mid waxtar u leh codsiyada warshadaha kala duwan, sida cuntada, daawooyinka, alaabta daryeelka shakhsi ahaaneed, iyo saabuunta, iyo kuwo kale.
