Sodium Carboxy methyl cellulose

SodiumCarboxymethyl cellulose

Sodium carboxymethyl cellulose (CMC), oo sidoo kale loo yaqaan: Sodium CMC, xanjo cellulose, CMC-Na, waa cellulose ether derivatives, taas oo ah tan ugu isticmaalka badan iyo qadarka ugu badan ee adduunka. waa cellulosics leh heerka gulukooska polymerization ee 100 ilaa 2000 iyo cufnaanta molecular ee 242.16. Budada suufka cad ama granular. Aan ur lahayn, aan dhadhamin, aan dhadhamin, hygroscopic, aan lagu milmin dareerayaasha organic.

CMC waa ether-ka anionic cellulose, budo fibros ah oo cad ama caano leh, cufnaanta 0.5-0.7 g/cm3, ku dhawaad ​​ur, aan dhadhamin, iyo hygroscopic. Si fudud ugu kala firdhi biyaha galay xal jel ah oo hufan, oo aan lagu milmi karin dareerayaasha organic sida ethanol. pH ee 1% xal aqueous waa 6.5-8.5. Marka pH>10 ama <5, viscosity ee koollada si weyn ayay u yaraan doontaa, iyo waxqabadka ugu fiican marka pH=7. Degen si loo kululeeyo, viscosity-ku si degdeg ah ayuu uga kacaa 20°C, wuxuuna si tartiib ah isu beddelaa 45°C. Kuleyliyaha muddada-dheer ee ka sarreeya 80 ° C wuxuu diidi karaa kolloid-ka wuxuuna si weyn u dhimi karaa viscosity-kiisa iyo waxqabadkiisa. Waxay si fudud ugu milmi kartaa biyaha, xalkuna waa mid hufan; aad bay ugu xasilloon tahay xalalka alkaline-ka, si fududna waa loo nadiifiyaa marka ay la kulanto aashitada. Waxay soo da'i doontaa marka pH-ku yahay 2-3, waxayna sidoo kale la falcelin doontaa milix bir ah oo polyvalent ah si ay u soo degto.

Codsiga

  1. Heerka cuntada CMC

Sodium carboxymethyl cellulose CMC ma aha oo kaliya xasilin emulsion wanaagsan iyo dhumuc ee codsiyada cuntada, laakiin sidoo kale waxay leedahay qaboojin aad u fiican iyo xasilloonida dhalaalaysa, iyo hagaajin kartaa dhadhanka alaabta iyo kordhin waqtiga kaydinta. Qadarka loo isticmaalo caanaha soyka, jalaatada, jalaatada, jelly, cabitaanada, iyo gasacadaha waa qiyaastii 1% ilaa 1.5%. CMC waxa kale oo lagu dari karaa khal, suugo soy, saliid khudradeed, casiir khudradeed, maraqa, casiirka khudradda, iwm. Gaar ahaan saliidaha xoolaha iyo khudradda, borotiinada iyo xalalka aqueous, waxay leedahay waxqabadka emulsification heer sare ah.

  1. Saabuunta darajada CMC

Sodium carboxymethyl cellulose CMC waxaa loo isticmaali karaa sida wakiilka dib-u-soo-celinta ciidda, gaar ahaan saameynta dib-u-soo-celinta ciidda ee dharka fiber synthetic hydrophobic, taas oo si weyn uga fiican fiber karboxymethyl.

  1. Qodista saliidda darajada CMC

Sodium carboxymethyl cellulose CMC waxaa loo isticmaali karaa in lagu ilaaliyo ceelasha saliidda sidii dhoobo-dejiye iyo wakiilka biyaha ee qodista saliidda. Cunista ceel kasta oo saliid ah waa 2.3t ceelasha gacmeed iyo 5.6t ee ceelasha qoto dheer;

  1. darajada Dharka CMC

CMC oo loo isticmaalo warshadaha dunta sida wakiilka cabbirka, dhumucsada daabacaadda iyo koollada rinjiyaynta, daabacaadda dunta iyo dhamaystirka adkaynta.
