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).Amabakala 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.
