1. Sodium Carboxymethyl Cellulose
Xabagta daabacaadda falcelinta leh waa soosaar leh qaab-dhismeed ether ah oo lagu helay wax-ka-beddel kiimikaad ee cellulose dabiiciga ah.Waa xabag biyaha ku milma oo lagu milmi karo biyo qabow iyo biyo kulul.Xalka aqueous waxa uu leeyahay hawlaha isku xidhka, dhumuc, kala firdhiyey, laalista iyo xasilinta.
Xabagta daabacaadda falcelinta ah waa wax soo saarka sodium carboxymethyl cellulose oo leh heerar sare oo etherification ah.Habka gaarka ah wuxuu ka dhigayaa kooxdeeda aasaasiga ah ee hydroxyl si buuxda loo beddelo, si looga fogaado falcelinta dheeha falcelinta.
Sida dhumucda daabacaadda daabacaadda, koollada daabacaadda falcelinta waxay dejin kartaa viscosity, hagaajinta dareeraha koollada, kor u qaadida awoodda hydrophilic ee dheeha, samaynta midabaynta midabaynta waxayna yaraynaysaa farqiga midabka;Isla mar ahaantaana, habka dhaqidda ka dib daabacaadda iyo dheehidda, heerka dhaqidda ayaa sarreeya, Dharka ayaa dareemaya jilicsanaanta taabashada.
2. Isbarbardhigga sifooyinka koollada daabacaadda falcelinta ah iyo sodium alginate
2.1 Dheji heerka
Marka la barbardhigo sodium alginate, koollada daabacaadda falcelinta waxay leedahay viscosity sare, haddii loo isticmaalo kaligaa ama lagu daro dhumucyada kale, waxay si wax ku ool ah u yareyn kartaa qiimaha koollada;Caadi ahaan, koollada firfircoon ee daabacaadda qiyaasta qiyaasta ayaa ah 60-65% oo keliya sodium alginate.
2.2 Midabka soo saarista iyo dareenka
Midabka koollada daabacaadda ee lagu diyaariyey koollada daabacaadda falcelinta leh sida dhumucdiisu waxay u dhigantaa tan sodium alginate, iyo marada ayaa dareema jilicsan ka dib marka la nadiifiyo, taas oo u dhiganta alaabta koollada alginate ee sodium.
2.3 Ku dheji xasilloonida
Sodium alginate waa kolloid-dabiici ah, kaas oo leh dulqaad liidata microorganisms, waqti gaaban kaydinta koollada midabka, oo ay fududahay in la xumeeyo.Xasiloonida soodhiyamka caadiga ah ee carboxymethyl cellulose waxay aad uga sareysaa ta sodium alginate.Alaabooyinka koollada daabacaadda firfircooni leh ayaa lagu hagaajiyay hannaan gaar ah, iyo iska caabintooda korantada ayaa ka wanaagsan soodhiyamka carboxymethyl cellulose caadiga ah.Isla mar ahaantaana, waxay leeyihiin iswaafajin wanaagsan oo ay la socdaan kaaliyeyaasha kiimikada iyo midabaynta, mana fududa in la kharribo oo xumaado inta lagu jiro kaydinta.Dejinta kiimikaad aad ayey uga fiican tahay sodium alginate.
2.4 Rheology (kaabayaal)
Sodium alginate iyo CMC labadaba waa dareeraha pseudoplastic, laakiin sodium alginate waxay leedahay viscosity qaabdhismeed hooseeya iyo qiimaha sare ee PVI, sidaas darteed kuma habboona daabacaadda wareega (flat) ee shaashadda, gaar ahaan daabacaadda shaashadda sare ee mesh;Alaabooyinka koollada daabacaadda falcelinta leh waxay leeyihiin viscosity qaabdhismeed sare, qiimaha PVI wuxuu ku saabsan yahay 0.5, fududahay in la daabaco qaabab cad iyo xariiqyo.Isku dhafka sodium alginate iyo koollada daabacaadda firfircoon waxay buuxin karaan shuruudo badan oo rheological ah ee dhejiska daabacaadda
