CMC Carboxymethyl Cellulose

Sharaxaad Gaaban:

CAS: 9004-32-4

Carboxymethyl Cellulose (CMC) waa polymer-ka-milanka biyaha anionic oo laga soo qaatay polymer-ka adduunka ugu badan – cellulose cudbi. Waxa kale oo loo yaqaan xanjo cellulose , iyo cusbada soodhiyamka ayaa ah derivatives cellulose muhiim ah.Kooxaha carboxymethyl ee xidhan (-CH2-COOH) oo ay weheliyaan silsiladda polymer ayaa ka dhigaysa cellulose-ka biyaha-milmay.Marka la kala diro, waxay kordhisaa viscosity ee xalal aqueous, ganaax iyo emulsions, iyo at fiirsashada sare, waxa ay bixisaa caag ah ama thixotropy.Sida polyelectrolyte-ka dabiiciga ah, CMC waxay siisaa kharash dusha sare ah qaybaha dhexdhexaadka ah waxaana loo isticmaali karaa si loo hagaajiyo xasilloonida kolloids aqueous iyo gels ama si loo kiciyo agglomeration.Waxay bixisaa sifooyin wanaagsan oo dhumucdiisuna, haynta biyaha, filim-samaynta, rheology iyo lubricity, taas oo si weyn loo isticmaalo in cuntada, alaabta daryeelka shakhsi ahaaneed, rinji warshadaha, ceramics, qodista saliidda, qalabka dhismaha iwm.

Faahfaahinta Alaabta

Tags Product

Carboxymethyl cellulose (CMC) waa polymer biyo-milmi leh anionic oo laga helay cellulose.Waxa ay leedahay dhumuc aad u fiican, nuugista, iyo sifada haynta biyaha, waxaana loo istcimaalaa noocyo badan oo codsiyo ah oo ay ku jiraan cuntada iyo quudinta lagu daro, waxyaalaha la isku qurxiyo, dhumucyada iyo walxaha xidha, xidhayaasha, alaabta biyaha nuugta, iyo wakiilada biyaha celiya.Maaddaama maaddadu ay ka timid cellulose dabiiciga ah, waxay soo bandhigtaa biodegradability tartiib tartiib ah waxaana la gubi karaa isticmaalka ka dib, taasoo ka dhigaysa walxo deegaanka u fiican.

Solubility of Carboxymethyl Cellulose (CMC)

Carboxymethyl Cellulose (CMC) waa walaxda dabiiciga ah ee hydrophilic marka sodium carboxymethyl cellulose particles ku firdhiso biyaha, isla markiiba way barari doontaa ka dibna milmi doontaa.
1. Marka la eego xaaladda walaaqda, ku darida sodium cmc si tartiib ah waxay caawisaa in la dedejiyo kala dirida.
2. Marka la eego xaalada kuleyliyaha, ku darida sodium cmc kala firidhsan waxay kordhin kartaa heerka kala dirida, laakiin kulaylku ma noqon karo mid aad u sarreeya wuxuuna ku habboon yahay 50-60 ° C.
3. Haddii loo isticmaalo in lagu qaso walxo kale, marka hore isku dar adkahaaga ka dibna milmaan, sidaas awgeed, xawaaraha kala diriddu sidoo kale waa la kordhin karaa.
Ku dar nooc ka mid ah dareerayaasha organic kuwaas oo aan lagu milmin sodium cmc laakiin lagu milmo biyo sida ethanol iyo glycerin ka dibna milaan, markaa habkan, xawaaraha xalku wuxuu noqon karaa mid aad u degdeg ah.
