Carboxymethyl Cellulose
Imbonakalo:umgubo omhlophe okanye ubisi omhlophe
Iimpawu zomzimba:yi-cellulose derivative kunye namaqela e-carboxymethyl (-CH2-COOH) ebophelelwe kwamanye amaqela e-hydroxyl ye-glucopyranose monomers eyenza i-cellulose backbone.Ikwabizwa ngokuba yiCMC, Carboxymethyl.I-Cellulose Sodium, ityuwa yeSodium yeCaboxy Methyl Cellulose.I-CMC yenye yeyona polyelectrolyte enyibilikayo yamanzi ebalulekileyo.Inokunyibilika emanzini, inganyibiliki etywaleni, ethanol, benzene, chloroform kunye nezinye izinyibilikisi eziphilayo.Ukumelana neoyile yezilwanyana kunye nemifuno kwaye ayisebenzi ngokukhanyisa.

Isicelo: I-CMC (ebizwa ngokuba “yi-industril gourmet powder”) luhlobo olumele i-cellulose ether kwi-fiber enyibilikayo ephuma emanzini, esetyenziswa kakhulu kumashishini okulungisa ukutya, isiselo se-lactic acid kunye nentlama yamazinyo, njl. njl., kwaye idlala indima ebalulekileyo kulo lonke ishishini okanye urhwebo njenge-emulsifier, i-arhente yokulinganisa .stabilizer,thickener,retarder,film yangaphambili,i-arhente echithachithayo,i-age emisiweyo,i-adhisive,i-arhente e-mercerizing,i-arhente ekhanyisayo kunye ne-arhente yokulungisa umbala,njl, ineenzuzo ezininzi zendalo eziqhelekileyo kunye nonxibelelwano. .
