ICarboxymethyl Cellulose (isiNgesi: iCarboxymethyl Cellulose, iCMC ngokufutshane) sisidibaniso sokutya esisetyenziswa ngokuqhelekileyo, kwaye ityuwa yayo yesodium (sodium carboxymethyl cellulose) isoloko isetyenziswa njengesityebi kunye nokuncamathelisa.
I-Carboxymethyl cellulose ibizwa ngokuba yi-industrial monosodium glutamate, esetyenziswa kakhulu kwimveliso yemizi-mveliso kwaye izisa ixabiso elikhulu lokusetyenziswa kwiinkalo ezahlukeneyo zemveliso. I-Carboxymethyl cellulose yinto engumgubo, ayinayo ityhefu, kodwa kulula ukuyinyibilika emanzini. Iyanyibilika emanzini abandayo nasemanzini ashushu, kodwa ayinyibiliki kwizinyibilikisi zendalo. Iya kuba yi-viscous liquid emva kokunyibilika, kodwa i-viscosity iya kuhluka ngenxa yokunyuka kweqondo lokushisa kunye nokuwa. Ngenxa yeempawu zayo ezikhethekileyo, kukho iimfuno ezininzi ezikhethekileyo zokugcina kunye nokuthutha.
Iimpawu zomzimba kunye neekhemikhali
I-Carboxymethyl cellulose yinto emhlophe okanye ekhaphukhaphu etyheli, engenavumba, engenancasa, iigranules zehygroscopic, umgubo okanye iifiber ezicolekileyo.
※Pukulungiswa
I-Carboxymethylcellulose yenziwa yi-base-catalyzed reaction ye-cellulose kunye ne-chloroacetic acid. Amaqela e-polar (organic acid) e-carboxyl enza i-cellulose inyibilike kwaye isebenze ngokwekhemikhali. Emva kokusabela kokuqala, umxube wesiphumo uvelise malunga ne-60% ye-CMC kunye ne-40% yeetyuwa (i-sodium chloride kunye ne-sodium glycolate). Imveliso yinto ebizwa ngokuba yi-CMC yezoshishino yezokucoca. Ezi tyuwa zisuswa kusetyenziswa inkqubo yokucoca eyongezelelweyo ukuvelisa i-CMC ecocekileyo ukuze isetyenziswe ekutyeni, kumayeza kunye namazinyo (i-toothpaste). Amabanga aphakathi “ahlanjululwe semi-purified” nawo ayaveliswa, adla ngokusetyenziswa kwizicelo zephepha ezifana nokubuyiselwa kwamaxwebhu angoovimba. Iimpawu ezisebenzayo ze-CMC zixhomekeke kwiqondo lokutshintshwa kwesakhiwo se-cellulose (oko kukuthi, mangaphi amaqela e-hydroxyl athatha inxaxheba ekuphenduleni ukutshintshwa), kunye nobude bekhonkco le-cellulose backbone structure kunye neqondo lokudityaniswa kwe-cellulose backbone. . Indawo yeCarboxymethyl.
※Aisicelo
I-Carboxymethylcellulose isetyenziselwa ukutya njenge-viscosity modifier okanye i-thickener phantsi kwenombolo ye-E466 okanye i-E469 (nge-enzymatic hydrolysis) kunye nokuzinzisa i-emulsions kwiimveliso ezahlukeneyo, kuquka i-ayisikrimu. Ikwayinxalenye yeemveliso ezininzi ezingezizo ukutya ezifana nentlama yamazinyo, izinto zokuthambisa, iipilisi zedayethi, ipeyinti esekwe emanzini, izicoci, izinto zokulinganisa amalaphu, ukupakishwa okuphinda kusetyenziswe ubushushu kunye neemveliso zamaphepha ezahlukeneyo. Isetyenziswa ikakhulu ngenxa yokuba i-viscosity ephezulu, ayinayo ityhefu kwaye ithathwa njenge-hypoallergenic njengoko eyona micu iphambili ingumtya womthi othambileyo okanye iilitha zomqhaphu. I-Carboxymethylcellulose isetyenziswa ngokubanzi kwi-gluten-free kunye nokutya okuncitshisiweyo okunamafutha. Kwizinto zokucoca iimpahla, isetyenziswa njengomhlaba oxhoma ipolymer eyenzelwe ukufaka umqhaphu kunye namanye amalaphu e-cellulosic, idala umqobo ohlawuliswa kakubi kumhlaba wotywala bokuhlamba. I-Carboxymethylcellulose isetyenziswa njenge-lubricant kwiinyembezi zokwenziwa. I-Carboxymethylcellulose iphinda isetyenziswe njenge-ejenti yokuqina, umzekelo, kwishishini lokugaya ioli, apho liyinxalenye yodaka lokugaya, apho lisetyenziswe njenge-modifier viscosity kunye ne-agent yokugcinwa kwamanzi. Umzekelo, i-sodium CMC (Na CMC) yayisetyenziswa njengolawulo olubi lokulahleka kweenwele kwimivundla. Amalaphu ezinithiweyo enziwe ngeselulosi, anjengomqhaphu okanye i-viscose rayon, anokuguqulwa abe zii-CMCs kwaye asetyenziswe kwizicelo ezahlukeneyo zonyango.
