Carboxymethylcellulose (CMC) iyo istaarijku waa labadaba polysaccharides, laakiin waxay leeyihiin qaabab, hanti iyo codsiyo kala duwan.
Halabuurka molecular:
1. Carboxymethylcellulose (CMC):
Carboxymethylcellulose waa nooc ka soo jeeda cellulose, polymer toosan oo ka kooban unugyo gulukoos oo ku xiran β-1,4-glycosidic bonds.Wax ka beddelka cellulose waxay ku lug leedahay hordhaca kooxaha karboxymethyl iyada oo loo marayo etherification, soo saarida karboxymethylcellulose.Kooxda karboxymethyl waxay ka dhigtaa CMC biyo-milmi kara waxayna siisaa polymer-ka sifooyin gaar ah.
2. Istaarij:
Istaarjku waa karbohaydrayt ka kooban unugyo gulukoos oo ay ku xidhan yihiin α-1,4-glycosidic bonds.Waa polymer-dabiiciga ah ee laga helo dhirta oo loo isticmaalo isku-xidhka kaydinta tamarta.Unugyada istaarijku waxay guud ahaan ka kooban yihiin laba nooc oo gulukoos polymers ah: amylose (silsilad toosan) iyo amylopectin (qaab-dhismeedka silsiladaha laanta).
Tilmaamaha jirka:
1. Carboxymethylcellulose (CMC):
Solubility: CMC waa biyo-milmi kara iyadoo ay ugu wacan tahay joogitaanka kooxaha karboksymethyl.
Viscosity: Waxay soo bandhigtaa viscosity sare ee xalka, taasoo ka dhigaysa mid qiimo leh codsiyada kala duwan sida diyaarinta cuntada iyo daawooyinka.
Daah-furnaan: Xalalka CMC caadi ahaan waa daah-furan.
2. Istaarij:
Solubility: istaarijka dhaladka ah waa mid aan lagu milmi karin biyaha.Waxay u baahan tahay gelatinization (kuleylka biyaha) si ay u milmaan.
Viscosity: Xabagta istaarijku waxay leedahay viscosity, laakiin guud ahaan way ka hoosaysaa CMC.
Daah-furnaan: Xadhkaha istaarijku waxay u muuqdaan inay noqdaan kuwo mugdi ah, iyo heerka indho-furnaantu way kala duwanaan kartaa iyadoo ku xidhan nooca istaarijka.
xigasho:
1. Carboxymethylcellulose (CMC):
CMC waxaa sida caadiga ah laga sameeyaa cellulose laga helo ilaha dhirta sida saxarka alwaax ama suufka.
2. Istaarij:
Dhirta sida galleyda, qamadiga, baradhada iyo bariiska ayaa qani ku ah istaarijka.Waa shay muhiim u ah cuntooyin badan oo daruuri ah.
Habka wax soo saarka:
1. Carboxymethylcellulose (CMC):
Wax soo saarka CMC waxay ku lug leedahay falcelinta etherification ee cellulose leh chloroacetic acid ee dhexdhexaad ah alkaline.Dareen-celintani waxay keentaa beddelka kooxaha hydroxyl ee cellulose leh kooxaha karboxymethyl.
2. Istaarij:
Soo saarista istaarijku waxay ku lug leedahay burburinta unugyada dhirta iyo go'doominta granules istaarijka.Istaarijka la soo saaray wuxuu mari karaa habab kala duwan, oo ay ku jiraan wax ka beddelka iyo jelatinization, si loo helo guryaha la rabo.
Ujeedada iyo codsiga:
1. Carboxymethylcellulose (CMC):
Warshadaha cuntada: CMC waxa loo isticmaalaa dhumuc weyn, xasiliye iyo emulsifier ee cuntooyinka kala duwan.
Daawooyinka: Sababo la xidhiidha xidhmooyinkeeda iyo guryaha burburay awgeed, waxa ay ogaatay in loo isticmaalo hababka dawooyinka.
Qodista Saliidda: CMC waxa loo isticmaalaa dareeraha qodista saliidda si loo xakameeyo rheology-ga.
2. Istaarij:
Warshadaha cuntada: Istaarjku waa qaybta ugu muhiimsan ee cuntooyinka badan waxaana loo isticmaalaa sida wakiilka dhumucda, wakiilka gelling iyo xasiliye.
Warshadaha Dharka: Istaarjka waxaa loo isticmaalaa cabbirka dharka si ay u adkeeyaan dharka.
Warshadaha waraaqaha: Istaarjka waxaa loo isticmaalaa samaynta waraaqaha si loo kordhiyo xoogga warqadda loona hagaajiyo sifooyinka dusha sare.
In kasta oo CMC iyo istaarijku labaduba yihiin polysaccharides, waxay ku kala duwan yihiin halabuurka molecular, sifooyinka jirka, ilaha, hababka wax soo saarka iyo codsiyada.CMC waa biyo-milmi leh oo aad u muuqda waxaana inta badan lagu door bidaa codsiyada u baahan guryahan, halka istaarijku yahay polysaccharide kala duwan oo si ballaaran loogu isticmaalo warshadaha cuntada, dharka iyo waraaqaha.Fahamka kala duwanaanshahan ayaa muhiim u ah doorashada polymer-ka ku habboon codsiyada warshadaha iyo ganacsiga gaarka ah.
