Habka wax soo saarka iyo sifooyinka Sodium Carboxymethyl Cellulose

Sodium carboxymethyl cellulose (Na-CMC) waa polymer biyo-milmi leh oo laga soo qaatay cellulose, kaas oo si weyn loogu isticmaalo codsiyada warshadaha kala duwan sida cuntada, daawooyinka, qurxinta, dunta, iyo qodista saliidda. Waxay caan ku tahay dhumucdeeda, xasilinta, iyo guryaha xidhidhkeeda aad u wanaagsan. Maqaalkan, waxaan ka wada hadli doonaa habka wax soo saarka iyo sifooyinka sodium carboxymethyl cellulose.

Habka wax soo saarka ee Sodium Carboxymethyl Cellulose

Soo saarista Na-CMC waxay ku lug leedahay dhowr tillaabo, oo ay ku jiraan soo saarista cellulose ee saxarka alwaax, suufka suufka, ama ilo kale, oo ay ku xigto wax ka beddelka cellulose si loo abuuro kooxo karboxymethyl ah. Habka wax soo saarka ee Na-CMC waxaa lagu soo koobi karaa sida soo socota:

1. Soo saarista Cellulose: Cellulose waxaa laga soo saaraa saxarka alwaax ama ilo kale iyada oo loo marayo taxane ah daawaynta makaanikada iyo kiimikaad, oo ay ku jiraan miirida, bleaching, iyo sifaynta.
2. Daaweynta Alkali: cellulose-ka la soo saaray waxaa lagu daaweeyaa xal alkaline ah oo xooggan, sida caadiga ah sodium hydroxide (NaOH), si ay u bararaan fiilooyinka cellulose oo ay u soo bandhigaan kooxaha hydroxyl fal-celinta.
3. Etherification: Fiyuusyada cellulose-ka ee barara ayaa markaa lagu falceliyaa sodium monochloroacetate (SMCA) iyada oo ay jirto joogitaanka kicinta alkaline sida sodium carbonate (Na2CO3) si loogu soo bandhigo kooxaha karboxymethyl ee lafdhabarta cellulose.
4. Dhexdhexaadinta: Carboxymethylated cellulose ayaa markaas lagu dhex milmay aashito sida hydrochloric acid (HCl) ama sulfuric acid (H2SO4) si loo sameeyo Na-CMC.
5. Nadiifinta iyo qallajinta: Na-CMC waxaa lagu nadiifiyaa maydhista iyo shaandhaynta si looga saaro wixii wasakh ah ka dibna la qalajiyo si loo helo budo bilaash ah.

Astaamaha Sodium Carboxymethyl Cellulose

Guryaha Na-CMC way kala duwanaan karaan iyadoo ku xiran heerka beddelka (DS), taas oo tixraacaysa tirada kooxaha karboxymethyl ee unugga anhydroglucose (AGU) ee cellulose. Qaar ka mid ah sifooyinka muhiimka ah ee Na-CMC waa:

1. Solubility: Na-CMC waa mid aad u biyo-milmi kara waxayna samayn kartaa xalal cad oo muuqda oo biyaha ah.
2. Viscosity: viscosity ee xalalka Na-CMC waxay kuxirantahay diirada, DS, iyo miisaanka kelli ee polymerka. Na-CMC waxay caan ku tahay sifooyinkeeda dhumucyada oo aad u wanaagsan waxaana loo isticmaali karaa in lagu kordhiyo viscosity ee xalalka iyo ganaaxyada.
3. Xasiloonida pH: Na-CMC waxay ku xasiloon tahay tiro balaadhan oo ah qiyamka pH, laga bilaabo acidic ilaa alkaline, taasoo ka dhigaysa mid ku haboon isticmaalka codsiyada kala duwan.
4. Dulqaadka Cusbada: Na-CMC aad bay ugu dulqaadanaysaa milixda waxayna ilaalin kartaa viscosity-keeda iyo xasilloonida joogitaanka elektrolytka.
5. Dejinta kulaylka: Na-CMC waa mid degan heerkulka sare waxaana loo isticmaali karaa hababka warshadaha kala duwan ee u baahan xaaladaha heerkulka sare.
6. Biodegradadability: Na-CMC waa biodegradable oo si badbaado leh loogu tuuri karaa deegaanka.

Gabagabo

Sodium carboxymethyl cellulose waa polymer-ka badan oo si weyn loogu isticmaalo codsiyada warshadaha kala duwan ay sabab u tahay dhumucdiisuna aad u fiican, xasilinta, iyo guryaha xidhitaan. Habka wax soo saarka ee Na-CMC waxay ku lug leedahay soo saarista cellulose oo ay ku xigto wax ka beddelka cellulose si loo abuuro kooxaha karboxymethyl. Na-CMC waxay leedahay sifooyin dhowr ah sida milanka, viscosity, xasiloonida pH, dulqaadka cusbada, xasiloonida kulaylka, iyo biodegradability, taas oo ka dhigaysa mid ku haboon isticmaalka codsiyada kala duwan. Guryaha Na-CMC waxaa lagu hagaajin karaa iyada oo la xakameynayo heerka beddelka, miisaanka kelliga, iyo xoojinta, taas oo ka dhigaysa qalab qiimo leh oo loogu talagalay hababka warshadaha kala duwan.
