1. Yini i-CMC?
CMC, Carboxymethylcellellulose, i-polymer ancibilike yamanzi eyenziwe ngokuguqulwa kwamakhemikhali kwe-cellulose yemvelo. Njengosengezo sokudla, i-kimacell®cmc ine-solubility enhle yamanzi, ukuqina nokuqina kwe-colloidal, futhi isetshenziswa kabanzi embonini yokudla. Enye yezindima zayo eziyinhloko ekukhiqizeni isinkwa ukwenza ngcono ukugcinwa kwamanzi, ngaleyo ndlela ethuthukisa ukuthungwa nokusha komkhiqizo.
2. Ukubaluleka kokugcinwa komswakama ngesinkwa
Ukugcinwa kwamanzi kwesinkwa kuyinto ebalulekile ekunqumeni ukunambitheka kwayo, ukuthungwa kanye nempilo eshalofini. Ukugcinwa kwamanzi okuhle kuvumela:
Gcina ukuthamba: vikela isinkwa ukuthi ungabi nzima futhi womile ngenxa yokulahleka komswakama.
Nweba impilo yeshelufu: Yehlisa ijubane lokuguga futhi lilibambezele ukubuyiselwa kwesitashi.
Kuthuthukisa ukugcwala kanye nokwakheka: kwenza isinkwa sinwebe futhi mancane amathuba okuthi siphule lapho silithambisa futhi sihlafuna.
Kodwa-ke, ekukhiqizweni kwangempela, ngenxa yokushisa okuphezulu ngesikhathi sokubhaka, umswakama enhlama kulula ukuhwamuka, futhi ngemuva kokubhaka, isinkwa futhi sithambekele ekulahlekelweni umswakama ngenxa yemvelo eyomile. Ngalesi sikhathi, ukungeza i-CMC kungathuthukisa kakhulu ukusebenza kokugcinwa kwamanzi kwesinkwa.
I-3. Inqubo ethile yesenzo ye-CMC ngesinkwa
(1) Ukufakwa kwamanzi okuthuthukisiwe nokugcinwa kwamanzi
Ama-molecule e-CMC aqukethe inani elikhulu lamaqembu e-carboxymethyl. Lawa maqembu ama-polar angakha ama-hydrogen bond ngama-molecule wamanzi, ngaleyo ndlela athuthukise kakhulu amandla okubopha kwamanzi kanye nokugcinwa. Ngesikhathi senqubo yokukhiqiza isinkwa, i-CMC ingasiza inhlama ukuba ithole amanzi amaningi, yandise okuqukethwe umswakama wenhlama, futhi kunciphise ukuhwamuka kwamanzi ngesikhathi sokubhaka. Noma ngesikhathi sokulondolozwa, i-CMC inganciphisa izinga lokulahleka kwamanzi futhi lilondoloze ukuthungwa okuthambile.
(2) Thuthukisa ukwakheka kanye nokukhohlisa kwenhlama
Njengomuntu omkhulu kanye ne-colloidal stabilizer, cmc ingathuthukisa izakhiwo ze-bhelogi lenhlama. Lapho ukuxubana kwenhlama, i-CMC ingakha isakhiwo senethiwekhi esixhumeke ngesitashi namaprotheni kufulawa, ngaleyo ndlela ithuthukise umthamo wokubamba amanzi yenhlama nokwenza inhlama ebanzi futhi yenza inhlama. Lesi sici futhi sisiza ukuthuthukisa ukuqina kwama-bubble omoya ngesikhathi sokubhaka, ekugcineni kwakheka isinkwa ngokuthungwa okufanayo nama-pores amahle.
(3) ukubambezela ukuguga kwesitashi
Ukuguga kwesitashi (noma ukubuyisa kabusha) kuyisizathu esibalulekile esenza isinkwa silahlekelwe ukuthamba kwaso. Ngemuva kokubhaka, ama-molecule wesitalashi esinkwa ahlela kabusha ukwakha amakristalu, enza isinkwa sibe nzima. I-KimaCell®cmc inganciphisa ngempumelelo ububanzi besinkwa yi-adderbing ebusweni be-starch molecule futhi bavimbele ukukhishwa kabusha kwamaketanga wesitashi.
(4) Ukushintshana nezinye izithako
I-CMC isetshenziswa ngokuhlanganiswa nezinye izengezo zokudla (ezifana ne-glycerin, emulsifiers, njll.) Ukuthuthukisa ukugcinwa kwamanzi. Isibonelo, i-CMC ingasebenza ngama-emulsifiers esakhiweni se-bubble senhlama ukuze sithuthukise ukuqina kwama-bubble, ngaleyo ndlela kunciphise ukulahleka kwamanzi ngesikhathi sokubhaka. Ngaphezu kwalokho, isakhiwo se-polymer chain ye-CMC singasebenza ngokuhlehlisa okufana ne-glycerin ukugcina umswakama wesinkwa.
4. Ungayisebenzisa kanjani i-CMC kanye nokuqapha
Emkhiqizweni wesinkwa, i-CMC ivame ukungezwa kwinhlama nge-powder noma isimo esincibilikisiwe. Umthamo othize ngokuvamile u-0.2% kuya ku-0.5% wekhwalithi yefulawa, kepha idinga ukulungiswa ngokuya ngohlobo lwefomula nohlobo lomkhiqizo. Amaphuzu alandelayo kufanele aqashelwe lapho usebenzisa:
I-Solubinity: I-CMC kufanele ichithwe ngokuphelele ukugwema ukwakheka kwezinhlayiya noma ama-agglomerates enhlama, okuthinta ukungaguquguquki kwenhlama.
Inani lezengezo: Ukusetshenziswa ngokweqile kwe-CMC kungadala ukuthi isinkwa sinambithe ama-sticky noma umswakama kakhulu, ngakho-ke inani lidinga ukulawulwa ngokunengqondo.
I-Recipe Balance: Umphumela we-synergistic we-CMC nezinye izithako ezifana nemvubelo, ushukela kanye nama-emulsifiers kungathinta ukunyuka kwesinkwa nokuthungwa, ngakho-ke iresiphi kufanele ilungiswe ngokuhlolwa.
5. Imiphumela yohlelo lokusebenza
Ngokungeza i-CMC, ukugcinwa kwamanzi kungathuthukiswa kakhulu. Okulandelayo yimiphumela eminingana ejwayelekile:
Umuzwa omanzi uthuthukiswa ngemuva kokubhaka: Ingaphakathi lesinkwa limanzi ngemuva kokusikwa, futhi ingaphezulu alimile futhi liqhekeke.
Ukunambitheka okulungiselelwe: kuthambile futhi kunwebeka kakhulu lapho uhlafuna.
Impilo eshehle enwetshiwe
6. Izitayela Zokuthuthuka Okuzayo
Njengoba ukufunwa kwabathengi kwemvelo kanye nokuphila kokudla kukhuphuka, ezinye izindlela ze-Kimacell®cmc ezinezithasiselo eziphansi noma imithombo yemvelo iyanakwa kancane kancane. Kodwa-ke, njenge-ejenti evuthiwe, eqinile futhi esebenza kahle yokugcina amanzi, i-CMC inesicelo esibanzi sokukhiqiza isinkwa. Esikhathini esizayo,CmUkuguqulwa kocwaningo (njengokuthuthukisa ukumelana ne-acid noma ukuhlanganisa namanye ama-colloids wemvelo) kungahle kunwebe ukukhulisa izinkambu zayo zohlelo lokusebenza.
Ngokufakwa kwayo okuhle kakhulu kwamanzi, ama-moisturizing and colloidal steability proceticies, i-CMC ihlinzeka ngokusekelwa okubalulekile kokwenza ngcono ukugcinwa kwezinkwa nokuthola impilo yayo eshalofini. Ungenye yezithasiselo ezingenakubaluleka embonini yanamuhla yokubhaka.
