Ukunyibilika kwemikhiqizo ye-Methyl Cellulose

Ukunyibilika kwemikhiqizo ye-Methyl Cellulose

I-Methyl cellulose iyi-polymer encibilika emanzini esetshenziswa kabanzi ezinhlelweni ezahlukahlukene zezimboni.Ukunyibilika kwemikhiqizo ye-methyl cellulose kuncike ezintweni ezahlukahlukene, kufaka phakathi izinga lokushintshwa, isisindo samangqamuzana, izinga lokushisa, kanye ne-pH.

Imikhiqizo ye-Methyl cellulose enezinga eliphansi lokushintshwa kanye nesisindo esiphansi samangqamuzana ancibilika kakhulu emanzini kunemikhiqizo enezinga eliphakeme lokushintshwa kanye nesisindo samangqamuzana esiphezulu.Imikhiqizo ye-Methyl cellulose enezinga eliphezulu lokushintsha kanye nesisindo samangqamuzana esiphezulu ingase idinge amazinga okushisa aphakeme noma izikhathi ezinde zokuhlanganisa ukuze incibilike ngokuphelele emanzini.

I-pH yesisombululo ingaphinda ithinte ukunyibilika kwe-methyl cellulose.Imikhiqizo ye-methyl cellulose inyibilika kakhulu kuzixazululo ezingathathi hlangothi noma ezine-acidic kancane.Emazingeni aphezulu we-pH, ukuncibilika kwe-methyl cellulose kuyehla.Lokhu kungenxa ye-ionization yamaqembu e-hydroxyl kumgogodla we-cellulose, okunganciphisa amandla ama-molecule wamanzi ukuxhumana namaketanga e-polymer.

Ngaphezu kwamanzi, imikhiqizo ye-methyl cellulose ingancibilika kwezinye izincibilikisi eziphilayo, njenge-ethanol, i-methanol, ne-acetone.Kodwa-ke, ukunyibilika kwe-methyl cellulose kulezi zinyibilikisi kunqunyelwe futhi kuncike ezingeni lokushintsha kanye nesisindo samangqamuzana omkhiqizo.

Sengiphetha, ukunyibilika kwemikhiqizo ye-methyl cellulose kuncike ezintweni ezahlukahlukene, kufaka phakathi izinga lokushintshwa, isisindo samangqamuzana, izinga lokushisa, kanye ne-pH.Imikhiqizo ye-Methyl cellulose enezinga eliphansi lokushintshwa kanye nesisindo esiphansi samangqamuzana ancibilika kakhulu emanzini, kuyilapho imikhiqizo enezinga eliphakeme lokushintshwa kanye nesisindo samangqamuzana esiphezulu ingase idinge amazinga okushisa aphakeme noma izikhathi ezinde zokuhlanganisa ukuze ichitheke ngokuphelele.Imikhiqizo ye-methyl cellulose inyibilika kakhulu ezixazululweni ezingathathi hlangothi noma ezine-acidic kancane, futhi ingancibilika kwezinye izinyibilikisi zemvelo, kodwa ukunyibilika kulezi zincibilikisi kunomkhawulo.
