1. Yini i-CMC?
I-CMC, i-carboxymethylcellulose, iyinhlanganisela ye-polymer encibilika emanzini eyenziwe ngokuguqulwa kwamakhemikhali e-cellulose yemvelo. Njengesengezo sokudla, i-KimaCell®CMC inokuncibilika okuhle kwamanzi, ukujiya kanye nokuzinza kwe-colloidal, futhi isetshenziswa kabanzi embonini yokudla. Enye yezindima zayo eziyinhloko ekukhiqizeni isinkwa ukuthuthukisa ukugcinwa kwamanzi kwesinkwa, ngaleyo ndlela kuthuthukise ukuthungwa kanye nokusha komkhiqizo.
2. Ukubaluleka kokugcina umswakama esinkwa
Ukugcinwa kwamanzi kwesinkwa kuyisici esibalulekile ekunqumeni ukunambitheka kwaso, ukuthungwa kanye nempilo yeshalofu. Ukugcinwa kahle kwamanzi kuvumela:
Gcina ukuthamba: Vimbela isinkwa ukuthi siqine futhi some ngenxa yokulahlekelwa umswakama.
Nweba impilo yeshalofu: nciphisa isivinini sokuguga futhi ubambezele ukubuyiswa kwesitashi.
Ithuthukisa ukunwebeka nokwakheka: Kwenza isinkwa sinwebeka futhi mancane amathuba okuthi siphuke lapho sisika futhi sihlafunwa.
Kodwa-ke, ekukhiqizeni kwangempela, ngenxa yokushisa okuphezulu ngesikhathi sokubhaka, umswakama enhlama kulula ukuhwamuka, futhi ngemva kokubhaka, isinkwa siphinde silahlekelwe umswakama ngenxa yemvelo eyomile. Ngalesi sikhathi, ukwengeza i-CMC kungathuthukisa kakhulu ukusebenza kwesinkwa sokugcinwa kwamanzi.
3. Indlela ethize yokusebenza kwe-CMC esinkwa
(1) Ukumuncwa kwamanzi okuthuthukisiwe kanye nokugcinwa kwamanzi
Ama-molecule e-CMC aqukethe inani elikhulu lamaqembu asebenzayo e-carboxymethyl. Lawa maqembu e-polar angakha izibopho ze-hydrogen ngama-molecule amanzi, ngaleyo ndlela athuthukise kakhulu amandla okubopha amanzi nokugcina. Phakathi nenqubo yokukhiqiza isinkwa, i-CMC ingasiza inhlama ukuba imunce amanzi amaningi, ikhulise umswakama wenhlama, futhi inciphise ukuhwamuka kwamanzi ngesikhathi sokubhaka. Ngisho nangesikhathi sokugcina, i-CMC inganciphisa izinga lokulahlekelwa kwamanzi esinkwa futhi igcine ukuthungwa okuthambile.
(2) Thuthukisa ukwakheka kanye ductility inhlama
Njenge-thickener ne-colloidal stabilizer, i-CMC ingathuthukisa izakhiwo ze-rheological zenhlama. Lapho uxuba inhlama, i-CMC ingakha isakhiwo senethiwekhi esixhumene nesitashi namaprotheni kufulawa, ngaleyo ndlela ithuthukise umthamo wokubamba amanzi wenhlama futhi yenza inhlama ibe nokunwebeka futhi idubule. Lesi sici siphinde sisiza ukuthuthukisa ukuzinza kwamabhamuza omoya ngesikhathi sokubhaka, ekugcineni sakhe isinkwa esinokuthungwa okufanayo kanye nezimbotshana ezinhle.
(3) Bambezela ukuguga kwesitashi
Ukuguga kwesitashi (noma ukubuyiselwa emuva) kuyisizathu esibalulekile esenza ukuthi isinkwa silahlekelwe ukuthamba kwaso. Ngemva kokubhaka, ama-molecule esitashi esinkwa ahlela kabusha ukuze akhe amakristalu, okwenza isinkwa sibe nzima. I-KimaCell®CMC inganciphisa ngempumelelo ukuqina kwesinkwa ngokukhangisa phezu kwama-molecule esitashi futhi ivimbele ukuhlelwa kabusha kwamaketango esitashi.
(4) I-synergy nezinye izithako
I-CMC isetshenziswa ngokuhlanganiswa nezinye izithasiselo zokudla (njenge-glycerin, ama-emulsifiers, njll.) ukuze kuthuthukiswe ukugcinwa kwamanzi kwesinkwa. Isibonelo, i-CMC ingasebenza nama-emulsifiers esakhiweni se-bubble senhlama ukuze kuthuthukiswe ukuzinza kwamabhamuza, ngaleyo ndlela kunciphise ukulahlekelwa kwamanzi ngesikhathi sokubhaka. Ngaphezu kwalokho, i-polymer chain structure ye-CMC ingasebenza nama-humectants afana ne-glycerin ukugcina umswakama wesinkwa.
4. Isetshenziswa kanjani i-CMC kanye nezinyathelo zokuphepha
Ekukhiqizweni kwesinkwa, i-CMC ivamise ukungezwa enhlama ibe yimpushana noma esimweni sokuncibilika. Umthamo othize ngokuvamile u-0.2% kuya ku-0.5% wekhwalithi kafulawa, kodwa udinga ukulungiswa ngokuvumelana nefomula kanye nohlobo lomkhiqizo. Amaphuzu alandelayo kufanele aqashelwe lapho usebenzisa:
I-Solubility: I-CMC kufanele ihlakazwe ngokugcwele ukugwema ukwakheka kwezinhlayiya noma ama-agglomerates enhlama, okuthinta ukuvumelana kwenhlama.
Inani elingeziwe: Ukusetshenziswa ngokweqile kwe-CMC kungase kubangele ukuthi isinkwa sinambitheke sinamathele noma siswakeme kakhulu, ngakho inani lidinga ukulawulwa ngendlela efanele.
Ibhalansi yeresiphi: Umthelela we-synergistic we-CMC nezinye izithako ezifana ne-yeast, ushukela kanye nama-emulsifiers kungase kuthinte ukukhuphuka kwesinkwa nokuthungwa, ngakho-ke iresiphi kufanele ithuthukiswe ngokuhlolwa.
5. Imiphumela yohlelo lokusebenza
Ngokungeza i-CMC, ukugcinwa kwamanzi kwesinkwa kungathuthukiswa kakhulu. Okulandelayo yimiphumela embalwa ejwayelekile:
Umzwelo omanzi uthuthukiswa ngemva kokubhaka: ingaphakathi lesinkwa linomanzi ngemva kokusikwa, futhi ubuso abubomile futhi buqhekekile.
Ukunambitheka okulungiselelwe: kuthambile futhi kuyanwebeka lapho uhlafuna.
Impilo yeshelufu eyandisiwe: Isinkwa sihlala sisisha ngemva kwezinsuku ezimbalwa zokugcinwa ekamelweni lokushisa futhi siqina ngokushesha kancane.
6. Izitayela zentuthuko yesikhathi esizayo
Njengoba isidingo sabathengi semvelo kanye nempilo yokudla sikhula, ezinye izindlela ze-KimaCell®CMC ezinezithasiselo eziphansi noma imithombo yemvelo ziya ngokuya ziqashelwa. Kodwa-ke, njenge-ejenti yokugcina amanzi evuthiwe, ezinzile futhi ephumelelayo, i-CMC isenamandla amakhulu okusebenza ekukhiqizeni isinkwa. Esikhathini esizayo,I-CMCucwaningo lokuguqulwa (njengokuthuthukisa ukumelana ne-asidi noma ukuhlanganisa namanye ama-colloid emvelo) lungase luqhubeke nokwandisa izinkambu zalo zokusetshenziswa.
Ngokumuncwa kwayo okuhle kakhulu kwamanzi, ukuthambisa kanye nezakhiwo zokuzinza kwe-colloidal, i-CMC inikeza ukwesekwa okubalulekile kokuthuthukisa ukugcinwa kwamanzi esinkwa nokwelula isikhathi saso seshalofu. Ingenye yezithako ezibalulekile embonini yesimanje yokubhaka.
