Ukusetyenziswa kwe-sodium carboxymethyl cellulose kunye ne-hydroxyethyl cellulose kwiimveliso zemichiza yemihla ngemihla

I-Carboxymethylcellulose sodium (CMC-Na) yinto ephilayo, i-carboxymethylated derivative ye-cellulose, kunye neyona nto ibalulekileyo ye-ionic cellulose gum. I-sodium carboxymethyl cellulose idla ngokuba yi-anionic polymer compound elungiselelwe ngokusabela i-cellulose yendalo kunye ne-alkali ye-caustic kunye ne-monochloroacetic acid, enobunzima bemolekyuli ukusuka kumawaka amaninzi ukuya kwizigidi. I-CMC-Na yi-fibrous emhlophe okanye i-granular powder, ayinavumba, ingenancasa, i-hygroscopic, ilula ukusasazeka emanzini ukwenza isisombululo se-colloidal esicacileyo.

Xa ingathathi hlangothi okanye i-alkaline, isisombululo singulwelo oluphezulu lwe-viscosity. Izinzile kumayeza, ukukhanya kunye nobushushu. Nangona kunjalo, ubushushu bukhawulelwe kwi-80°C, kwaye ukuba ishushu ixesha elide ngaphezu kwama-80°C, i-viscosity iya kuncipha kwaye ayiyi kunyibilika emanzini.

I-sodium carboxymethyl cellulose ikwaluhlobo lwe-thickener. Ngenxa yeempawu zayo ezilungileyo zokusebenza, isetyenziswe ngokubanzi kwishishini lokutya, kwaye ikwakhuthaze uphuhliso olukhawulezayo nolunempilo lweshishini lokutya ukuya kuthi ga kwinqanaba elithile. Ngokomzekelo, ngenxa yokuqina kwayo kunye ne-emulsifying effect, ingasetyenziselwa ukuzinzisa iziselo ze-yogurt kunye nokwandisa i-viscosity ye-yoghurt system; ngenxa yezinto ezithile ze-hydrophilicity kunye ne-rehydration, ingasetyenziselwa ukuphucula ukusetyenziswa kwe-pasta njengesonka kunye nesonka esiqhumayo. umgangatho, ukwandisa ubomi beshelufu yeemveliso zepasta kunye nokuphucula ukunambitha.

Ngenxa yokuba inefuthe elithile le-gel, kunenzuzo ekutyeni ukwenza i-gel engcono, ngoko ingasetyenziselwa ukwenza i-jelly kunye ne-jam; Isenokusetyenziswa njengezinto ezityiwayo zokugquma, ezidityaniswe nezinye izityebe, kwaye zisasazwe Kwindawo ethile yokutya, inokugcina ukutya kutsha ngowona mgangatho mkhulu, kwaye ngenxa yokuba zizinto ezityiwayo, aziyi kubangela iziphumo ezibi ebantwini. impilo. Ke ngoko, i-CMC-Na yebakala lokutya, njengesongezo sokutya esifanelekileyo, isetyenziswa kakhulu kwimveliso yokutya kwishishini lokutya.

IHydroxyethylcellulose (HEC), ifomula yemichiza (C2H6O2)n, imhlophe okanye iluhlaza tyheli, ayinavumba, ingenatyhefu okanye ilumgubo oluqinileyo, oluqulunqwe yialkaline cellulose kunye ne-ethylene oxide (okanye i-chlorohydrin) Ilungiselelwe ukusabela kwe-etherification, yeye-non- ionic cellulose ethers enyibilikayo. Ngenxa yokuba i-HEC ineempawu ezintle zokuqina, ukumisa, ukusabalalisa, i-emulsifying, ukubopha, ukwenza ifilimu, ukukhusela umswakama kunye nokubonelela nge-colloid yokukhusela.

Inyibilika ngokulula emanzini kwi-20°C. Ukunganyibiliki kwizinyibilikisi eziqhelekileyo eziphilayo. Inemisebenzi yokuqina, ukuxhoma, ukubopha, ukumilisela, ukusabalalisa, kunye nokugcina ukufuma. Izisombululo kwiindidi ezahlukeneyo ze-viscosity zinokulungiswa. Inonyibiliko olulungileyo lwetyuwa kwi-electrolytes.

I-viscosity iyatshintsha kancinci kuluhlu lwexabiso le-PH 2-12, kodwa i-viscosity iyancipha ngaphaya kolu luhlu. Ineempawu zokuqina, ukumisa, ukubopha, i-emulsifying, ukusabalalisa, ukugcina umswakama kunye nokukhusela i-colloid. Izisombululo kwiindidi ezahlukeneyo ze-viscosity zinokulungiswa.
