I-Methylcellulose (MC)iyinhlanganisela etholakala ku-cellulose futhi isetshenziswa kakhulu ekudleni, emithini, kwezimonyo nakwezinye izimboni. Kuyi-derivative cellulose encibilika emanzini ngokujiya okuthile, i-gelling, i-emulsification, ukumiswa nezinye izakhiwo.
Izakhiwo zamakhemikhali nezindlela zokukhiqiza ze-methylcellulose
I-Methylcellulose itholakala ngokuphendula i-cellulose (ingxenye eyinhloko yesakhiwo ezitshalweni) nge-agent ye-methylating (njenge-methyl chloride, i-methanol, njll.). Ngokusabela kwe-methylation, iqembu le-hydroxyl (-OH) le-cellulose lithathelwa indawo yiqembu le-methyl (-CH3) ukukhiqiza i-methylcellulose. Ukwakheka kwe-methylcellulose kufana neselulosi yasekuqaleni, kodwa ngenxa yezinguquko zayo zesakhiwo, ingancibilika emanzini ukuze yakhe isixazululo se-viscous.
I-solubility, viscosity kanye nezakhiwo ze-gelling ze-methylcellulose zihlobene eduze nezici ezifana nezinga le-methylation nesisindo samangqamuzana. Ngokwezidingo ezahlukene, i-methylcellulose ingenziwa ibe yizixazululo ze-viscosities ehlukene, ngakho-ke inezinhlobonhlobo zezicelo ezimbonini ezihlukahlukene.
Ukusetshenziswa okuyinhloko kwe-methylcellulose
Imboni yokudla
Embonini yokudla, i-methylcellulose isetshenziswa kakhulu njenge-thickener, stabilizer, emulsifier kanye ne-gelling agent. Isibonelo, ekudleni okunamafutha aphansi noma okungenawo amafutha, i-methylcellulose ingalingisa ukunambitheka kwamafutha futhi inikeze ukuthungwa okufanayo. Kuvame ukusetshenziselwa ukwenza ukudla osekulungele ukudliwa, ukudla okuqandisiwe, amaswidi, iziphuzo, nezingubo zesaladi. Ngaphezu kwalokho, i-methylcellulose ibuye isetshenziswe ezindaweni zemifino noma ezitshalweni njengesengezo sokusiza ukuthuthukisa ukunambitheka nokuthungwa.
Ukusetshenziswa Kwemithi
Embonini yezemithi, i-methylcellulose ivamise ukusetshenziswa njengesisetshenziswa sokwenza izidakamizwa, ikakhulukazi ama-ejenti alawulwayo akhulula izidakamizwa. Ingakhulula kancane kancane izidakamizwa emzimbeni, ngakho-ke i-methylcellulose ivamise ukusetshenziswa njengesithwali kwezinye iziyalezo zokukhishwa kwezidakamizwa ezilawulwayo. Ngaphezu kwalokho, i-methylcellulose isetshenziselwa ukulungisa izinyembezi zokwenziwa ukusiza ukwelapha izinkinga zamehlo ezifana namehlo omile.
Izimonyo Nemikhiqizo Yokunakekela Umuntu
I-Methylcellulose isetshenziswa njenge-thickener, stabilizer, kanye ne-moisturizer ezimonyoni, futhi ivame ukusetshenziswa emikhiqizweni enjengamafutha okugcoba, okhilimu, nama-shampoos. Ingakwazi ukwandisa i-viscosity nokuzinza komkhiqizo, okwenza umkhiqizo ube bushelelezi uma usetshenziswa.
Ukusetshenziswa Kwezimboni
I-Methylcellulose iphinde isetshenziswe kabanzi ezintweni zokwakha, ikakhulukazi kusimende, izinto zokunamathisela, nezinamathiselo, njenge-thickener kanye ne-emulsifier. Ingathuthukisa ukunamathela, uketshezi, nokusebenza komkhiqizo.
Ukuphepha kwe-methylcellulose
I-Methylcellulose iyikhemikhali ebhekwa kabanzi njengephephile. I-World Health Organization (WHO) kanye ne-US Food and Drug Administration (FDA) bobabili bakubheka njengesengezo esinobungozi obuncane. I-Methylcellulose ayigayeki emzimbeni futhi njenge-fiber yokudla encibilika emanzini, ingakhishwa ngokuqondile ngamathumbu. Ngakho-ke, i-methylcellulose inobuthi obuphansi futhi akukho monakalo osobala emzimbeni womuntu.
Imiphumela emzimbeni womuntu
I-methylcellulose ngokuvamile ayingeni emzimbeni. Kungasiza ukukhuthaza i-peristalsis yamathumbu futhi kusize ukukhulula izinkinga zokuqunjelwa. Njenge-fiber yokudla, inomsebenzi wokuthambisa nokuvikela amathumbu, futhi ingalawula ngisho namazinga kashukela egazini. Kodwa-ke, ukuphuza kakhulu i-methylcellulose kungase kubangele ukungakhululeki kwamathumbu, njenge-flatulence noma isifo sohudo. Ngakho-ke, kubaluleke kakhulu ukusebenzisa inani elifanele le-methylcellulose uma uyisebenzisa njengesithasiselo.
Imithelela kumthethosisekelo we-allergies
Nakuba i-methylcellulose ngokwayo ingajwayele ukungezwani nezinto ezithile, abanye abantu abazwelayo bangase babe nokungaphatheki kahle okuncane emikhiqizweni equkethe i-methylcellulose. Ikakhulukazi kwezinye izimonyo, uma umkhiqizo uqukethe ezinye izithako ezicasulayo, kungase kubangele ukungezwani kwesikhumba. Ngakho-ke, kungcono ukwenza ukuhlolwa kwendawo ngaphambi kokusetshenziswa.
Izifundo zokusebenzisa isikhathi eside
Njengamanje, ucwaningo lokuthatha isikhathi eside kwe-methylcellulose alukatholi ukuthi izodala izinkinga ezinkulu zempilo. Inombolo enkulu yocwaningo ibonise ukuthi i-methylcellulose, lapho isetshenziswa njengesengezo se-fiber yokudla, inomphumela othile omuhle ekuthuthukiseni ukuqunjelwa nokukhuthaza impilo yamathumbu.
Njengesengezo esiphephile sokudla nezidakamizwa, i-methylcellulose isetshenziswa kabanzi ezimbonini eziningi, okuhlanganisa ukudla, imithi, izimonyo, njll. Ngokuvamile ayinangozi emzimbeni womuntu, futhi uma isetshenziswe ngokusesilinganisweni, ingaletha ngisho nezinzuzo ezithile zezempilo, njenge ukuthuthukisa impilo yamathumbu kanye nokukhulula ukuqunjelwa. Nokho, ukudla ngokweqile kungase kubangele ukungakhululeki kwesisu, ngakho kufanele kusetshenziswe ngokulinganisela. Ngokuvamile, i-methylcellulose iyinto ephephile, ephumelelayo futhi esetshenziswa kabanzi.
