Guryaha Sodium Carboxymethyl cellulose iyo Waxyaabaha Saamayn ku leh CMC Viscosity

Sodium Carboxymethyl cellulose (CMC) waa polymer caadi ahaan loo isticmaalo codsiyada warshadaha kala duwan, oo ay ku jiraan cuntada, daawooyinka, alaabta daryeelka shakhsi ahaaneed, iyo saabuunta. Waa soosaar biyo-milmi leh oo cellulose ah oo ay soo saarto falcelinta cellulose leh chloroacetic acid iyo sodium hydroxide. CMC waa mid aad u kala duwan oo leh noocyo badan oo hanti ah oo ka dhigaya mid ku habboon codsiyada kala duwan. Maqaalkan, waxaan kaga hadli doonaa sifooyinka CMC iyo arrimaha saameeya viscosity.

Guryaha 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-jiifkiisu hoos u dhaco iyadoo 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. 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.
5. 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.

Waxyaabaha saameeya viscosity CMC:

1. Degree of Beddelka (DS): Darajada beddelka waa celceliska tirada kooxaha karboxymethyl unug anhydroglucose ee unugga cellulose. CMC oo leh DS sare ayaa leh heerar sare oo beddelaad ah, taas oo horseedaysa mawqif sare. Tani waa sababta oo ah DS sare wuxuu keenaa kooxo badan oo karboxymethyl ah, taas oo kordhisa tirada molecules biyaha ee ku xiran polymer-ka.
2. Xoog-saarista: Viscosity of CMC waxay kordhisaa feejignaanta sii kordheysa. Tani waa sababta oo ah xoojinta sare, silsilado polymer badan ayaa ku jira, taas oo horseedaysa heer sare oo isku dhejis ah iyo kororka viscosity.
3. pH: Viscosity ee CMC waxaa saameeya pH ee xalka. Marka pH yar tahay, CMC waxay leedahay viscosity sare sababtoo ah kooxaha karboksylku waxay ku jiraan qaabkooda protonated waxayna si xoog leh ula falgali karaan molecules biyaha. Marka pH-gu sareeyo, CMC waxay leedahay muuqa hoose sababtoo ah kooxaha karboksylku waxay ku jiraan qaabkooda bararka waxayna leeyihiin isdhexgalka molecules biyaha.
4. Heerkulka: Viscosity of CMC hoos ayuu u dhacaa marka uu kordho heerkulka. Tani waa sababta oo ah heerkulka sare, silsiladaha polymerku waxay leeyihiin tamar kulayl badan, taas oo u horseedaysa heer sare oo dhaqdhaqaaq ah iyo hoos u dhaca viscosity.
5. Feejignaanta Electrolytka: Viscosity of CMC waxaa saameeya joogitaanka electrolytes ee xalka. Heerarka sare ee elektrolytka, viscosity ee CMC ayaa hoos u dhacaya sababtoo ah ions ee xalka waxay la falgali karaan kooxaha karboksylka ee polymer waxayna yareeyaan isdhexgalka molecules biyaha.

Gebagebadii, Sodium Carboxymethyl cellulose (CMC) waa polymer aad u isku dhafan oo soo bandhigaya hanti aad u kala duwan, oo ay ku jiraan milanka, viscosity, rheology, xasilloonida, iyo guryaha sameynta filimada. Viscosity ee CMC waxaa saameeya arrimo kala duwan, sida heerka beddelka, fiirsashada, pH, heerkulka, iyo diiradda electrolyte. Fahamka arrimahan ayaa muhiim u ah wanaajinta waxqabadka CMC ee codsiyada kala duwan.
