Waa maxay sodium cmc?

Sodium Carboxymethyl Cellulose (CMC) waa polymer biyo-milmi leh oo laga soo qaatay cellulose, kaas oo ah polysaccharide si dabiici ah u dhaca oo laga helo gidaarada unugyada dhirta. CMC waxaa lagu soo saaraa daawaynta cellulose leh sodium hydroxide iyo monochloroacetic acid, taasoo keentay badeeco leh kooxaha karboxymethyl (-CH2-COOH) oo ku xiran laf dhabarta cellulose.

CMC waxaa caadi ahaan loo isticmaalaa warshado kala duwan, oo ay ku jiraan cuntada, dawooyinka, daryeelka shakhsi ahaaneed, iyo codsiyada warshadaha, sababtuna tahay sifooyinkeeda gaarka ah. Badeecooyinka cuntada, sodium CMC waxay u adeegtaa sidii wakiilka dhumuc, xasiliye, iyo emulsifier, hagaajinta qaabdhismeedka, joogteynta, iyo nolosha shelf. Daawooyinka, waxa loo istcimaalayaa xidhe ahaan, kala daadsan, iyo wax ka beddelka viscosity ee kiniiniyada, ganaaxyada, iyo boomaatada. Alaabooyinka daryeelka shakhsi ahaaneed, waxay u shaqeysaa sidii dhumuc, qoyaan, iyo wakiilka samaynta filimada ee waxyaalaha la isku qurxiyo, loshinka, iyo daawada cadayga. Codsiyada warshadaha, sodium CMC waxaa loo istcimaalaa xire ahaan, beddele rheology, iyo wakiilka luminta dareeraha ee rinjiga, saabuunta, dunta, iyo dareeraha qodista saliidda.

Sodium CMC ayaa laga door bidaa noocyada kale ee CMC (sida kalsiyum CMC ama potassium CMC) sababtoo ah milanka sare iyo xasilloonida xalalka aqueous. Waxaa lagu heli karaa darajooyin kala duwan iyo viscosities si ay ugu habboonaato codsiyada kala duwan iyo shuruudaha habaynta. Guud ahaan, sodium CMC waa wax lagu daro oo si ballaaran loo isticmaalo oo leh codsiyo badan oo warshado kala duwan ah.
