I-sodium carboxymethyl cellulose

I-sodium carboxymethyl cellulose (CMC-Na) yi-carboxymethylated derivative ye-cellulose kwaye yeyona ibalulekileyo 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.

2. Iimpawu zomzimba kunye neekhemikhali

I-CMC-Na emfutshane, emhlophe ukuya kumgubo omthubi, i-granular okanye i-fibrous substance, i-hygroscopicity enamandla, i-soluble kalula emanzini, kunye nesisombululo siphezulu se-viscosity liquid xa ingathathi hlangothi okanye i-alkaline. Izinzile kumayeza, ukukhanya kunye nobushushu. Nangona kunjalo, ukushisa kunqunyelwe kwi-80 ° C, kwaye ukuba kushushu ixesha elide ngaphezu kwe-80 ° C, i-viscosity iya kuncipha kwaye ayiyi kuxutywa emanzini. Ubuninzi bayo obusondeleyo buyi-1.60, kwaye ubuninzi beeflakes yi-1.59. Isalathisi se-refractive yi-1.515. Ijika ibentsundu xa ishushu kwi 190-205°C, ize ikharbhonize xa ishushu kwi 235-248°C. Ukunyibilika kwayo emanzini kuxhomekeke kwiqondo lokutshintshwa. Ayinyibiliki kwi-asidi kunye notywala, akukho mvula xa kukho ityuwa. Akulula ukubilisa, inamandla awomeleleyo e-oyile kunye newax, kwaye inokugcinwa ixesha elide.

3. Isicelo esiphambili

Isetyenziswa kakhulu kwishishini le-oyile ukumba iarhente yonyango lodaka, isicoci sokwenziwa, isakhi se-organic detergent, ushicilelo olulukiweyo kunye ne-ejenti yokudaya, i-colloidal tackifier enyibilikayo emanzini kwiimveliso zemichiza yemihla ngemihla, i-tackifier kunye ne-emulsifier yeshishini lamayeza, i-thickener yeshishini lokutya, i-adhesive for ceramic. ishishini, intlama yoshishino, i-agent agent kushishino lwephepha, njl. Isetyenziswa njenge-flocculant kunyango lwamanzi, isetyenziswa ikakhulu kunyango lwe-sludge yamanzi amdaka, enokunyusa umxholo oqinileyo wekhekhe lokucoca.

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 incasa; ngenxa yokuba inefuthe elithile le-gel, lilungele ukubunjwa okungcono kwe-gel ekudleni, ngoko ingasetyenziselwa ukwenza i-jelly kunye ne-jam; inokuphinda isetyenziswe njengefilimu etyiwayo yokugquma Izinto eziphathekayo zixutywe kunye nezinye i-thickeners kwaye zifakwe kumphezulu wokutya okunye, okunokugcina ukutya kutsha kwinqanaba elikhulu, kwaye ngenxa yokuba liyinto edliwayo, ayiyi kubangela ukungahambi kakuhle. iziphumo kwimpilo yabantu. Ke ngoko, i-CMC-Na yebakala lokutya, njengesongezo sokutya esifanelekileyo, isetyenziswa kakhulu kwimveliso yokutya kwishishini lokutya.
