Carboxymethyl cellulose (CMC)yi-anionic cellulose ether eyenziwe ngokuguqulwa kweekhemikhali zeselulosi. Isetyenziswa kakhulu kukutya, amayeza, iikhemikhali zemihla ngemihla, i-petroleum, i-papermaking kunye namanye amashishini ngenxa yokuqina kwayo okuhle, ukwenza ifilim, ukumilisela, ukumisa kunye nokuthambisa iipropathi. I-CMC inamabanga ahlukeneyo. Ngokobunyulu, iqondo lokuthatha indawo (DS), i-viscosity kunye neemeko ezisebenzayo, amabakala aqhelekileyo anokwahlulwa ngokwebakala loshishino, ibakala lokutya kunye nebakala loxubo-mayeza.
1. I-industrial grade carboxymethyl cellulose
Ibakala loShishino lweCMC yimveliso esisiseko esetyenziswa kakhulu kwiindawo ezininzi zoshishino. Isetyenziswa kakhulu kwiindawo zeoli, ukwenza iphepha, iiseramics, iingubo, ukuprinta kunye nokudaya kunye namanye amashishini, ngakumbi kunyango lodaka ekutsalweni kweoli kunye ne-ejenti yokuqinisa kwimveliso yephepha.
I-Viscosity: Uluhlu lwe-viscosity yebakala loshishino lwe-CMC lubanzi, ukusuka kwi-viscosity ephantsi ukuya kwi-viscosity ephezulu ukuhlangabezana neemfuno zezicelo ezahlukeneyo. I-viscosity ephezulu ye-CMC ifanelekile ukuba isetyenziswe njengesibophelelo, ngelixa i-viscosity ephantsi ifanelekile ukusetyenziswa njenge-thickener kunye ne-stabilizer.
I-Degree of substitution (DS): I-degree of substitution of general industrial-grade CMC iphantsi, malunga ne-0.5-1.2. Iqondo eliphantsi lokutshintshwa linokunyusa isantya apho i-CMC inyibilika emanzini, ivumela ukuba yenze ngokukhawuleza i-colloid.
Iindawo zesicelo:
Ukwemba i-oyile:CMCisetyenziswa njenge-thickener kunye ne-ejenti yokumisa ekugrumbeni udaka ukunyusa i-rheology yodaka kunye nokuthintela ukudilika kodonga lwequla.
Umzi-mveliso wokwenza amaphepha: I-CMC ingasetyenziswa njengesixhasi sepulp ukuphucula amandla okuqina kunye nokumelana nokusonga kwephepha.

Izinto eziluncedo: I-CMC ye-Industrial-grade inexabiso eliphantsi kwaye ifanelekile kwimveliso yemizi-mveliso emikhulu.
2. I-carboxymethyl cellulose yebakala lokutya
I-CMC yebakala lokutya isetyenziswa kakhulu kushishino lokutya, ikakhulu njenge-thickener, emulsifier, stabilizer, njl. Eli bakala le-CMC lineemfuno eziphezulu zococeko, imigangatho yococeko kunye nokhuseleko.
I-Viscosity: I-viscosity ye-CMC yebakala lokutya idla ngokuba phantsi ukuya phakathi, ilawulwa ngokubanzi phakathi kwe-300-3000mPa·s. I-viscosity ethile iya kukhethwa ngokwemeko yesicelo kunye neemfuno zemveliso.
I-Degree of substitution (DS): I-degree of substitution of food-grade CMC ilawulwa ngokubanzi phakathi kwe-0.65-0.85, enokubonelela nge-viscosity ephakathi kunye nokunyibilika okulungileyo.
Iindawo zesicelo:
Iimveliso zobisi: CMC isetyenziswa kwiimveliso zobisi ezifana ice cream kunye iyogathi ukwandisa viscosity kunye incasa yemveliso.
Iziselo: Kwijusi kunye neziselo zeti, i-CMC inokusebenza njengesizinzisi sokunqunyanyiswa ukukhusela i-pulp ukuba ingazinzi.
Ii-noodles: Kwi-noodles kunye ne-rice noodles, i-CMC inokunyusa ngokufanelekileyo ukuqina kunye nencasa yee-noodles, izenze zibe elastic ngakumbi.
Ii-Condiments: Kwi-sauces kunye ne-salad dressings, i-CMC isebenza njenge-thickener kunye ne-emulsifier ukunqanda ukwahlukana kwamanzi-oyile kunye nokwandisa ubomi beshelufu.
Iingenelo: I-CMC yodidi lokutya iyahlangabezana nemigangatho yokucoceka kokutya, ayinabungozi emzimbeni womntu, iyanyibilika emanzini abandayo kwaye inokukhawuleza yenze i-colloids, kwaye ineziphumo ezigqwesileyo zokujiya nokuzinzisa.
3. I-carboxymethyl cellulose ye-Pharmaceutical-grade
Pharmaceutical-gradeCMCifuna ukucoceka okuphezulu kunye nemigangatho yokhuseleko kwaye isetyenziswa ikakhulu kwimveliso yamayeza kunye nezixhobo zonyango. Eli bakala le-CMC kufuneka lihlangabezane nemigangatho ye-pharmacopoeia kwaye liphantsi kolawulo olungqongqo lwekhwalithi ukuze kuqinisekiswe ukuba alunatyhefu kwaye alucaphuki.
I-Viscosity: Uluhlu lwe-viscosity ye-CMC ye-pharmaceutical-grade icocwe ngakumbi, ngokubanzi phakathi kwe-400-1500mPa · s, ukuqinisekisa ukulawulwa kwayo kunye nokuzinza kwizicelo zonyango kunye nezonyango.
I-Degree of substitution (DS): Iqondo lokutshintshwa kwebakala leyeza lihlala liphakathi kwe-0.7-1.2 ukubonelela ngokunyibilika okufanelekileyo kunye nokuzinza.
Iindawo zesicelo:
Amalungiselelo eziyobisi: I-CMC isebenza njenge-binder kunye ne-disintegrant yamacwecwe, anokunyusa ukuqina kunye nokuzinza kweepilisi, kwaye inokutshabalalisa ngokukhawuleza emzimbeni.
I-Eye drops: I-CMC isebenza njenge-thickener kunye ne-moisturizer yamachiza ophthalmic, anokulinganisa iimpawu zeenyembezi, ukunceda ukuthambisa amehlo, kunye nokunciphisa iimpawu zamehlo omileyo.
Ukunxitywa kwamanxeba: I-CMC inokwenziwa ifilimu ecacileyo kunye nejeli-ezifana nejeli zokunyamekela amanxeba, kunye nokugcinwa kakuhle komswakama kunye nokuphefumla, ukukhuthaza ukuphiliswa kwenxeba.
Izinto eziluncedo: Ibakala lezonyango i-CMC idibana nemigangatho ye-pharmacopoeia, ine-biocompatibility ephezulu kunye nokhuseleko, kwaye ifanelekile ngomlomo, i-injection kunye nezinye iindlela zokulawula.
4. Amabakala akhethekileyo e-carboxymethyl cellulose
Ukongeza kula mabanga mathathu angasentla, i-CMC inokuthi ilungiswe ngokweemfuno ezithile zemimandla eyahlukeneyo, efana nebakala lokuthambisa i-CMC, ibakala le-CMC yentlama yamazinyo, njl.
Ibakala le-Cosmetic CMC: lisetyenziswa kwiimveliso zokhathalelo lwesikhumba, iimaski zobuso, njl., kunye nokwenza ifilimu elungileyo kunye nokugcinwa kokufuma.
Intlama yamazinyo yodidi lweCMC: isetyenziswa njengento ejiyayo kunye nencamathelayo ukunika intlama yamazinyo ibe yintlama engcono kunye nolwelo.
Carboxymethyl celluloseinoluhlu olubanzi lwezicelo kunye neendidi ezahlukeneyo zokhetho lwebakala. Ibakala ngalinye lineempawu ezithile zomzimba nezekhemikhali ukuhlangabezana neemfuno zamashishini ahlukeneyo.
