I-Hydroxypropylm methyl cellulose vs methyl cellulose

1. I-Hydroxypropyllylylyl methyl cellulose incibilika emanzini abandayo, amanzi ashisayo ancibilikisiwe azobhekana nobunzima. Kepha izinga lokushisa layo le-gelation emanzini ashisayo liphakeme kakhulu kunalelo ye-methyl cellulose. I-solubility ye-methyl cellulose emanzini abandayo nayo yathuthukiswa kakhulu.

2. I-viscoxpyprosil methyl celtule Ukushisa kuzophinda kuthinte ukubonakala kwayo, izinga lokushisa lenyuka, ukuhlakanipha kuyancipha. Kodwa-ke, i-viscosity yokushisa okuphezulu iphansi kunaleyo ye-methyl cellulose. Isixazululo sizinzile lapho zigcinwa emazingeni okushisa asekamelweni.

I-3. I-Hydroxypropyllylylylylylyllls isitebelelo i-acid ne-alkali, bese kuthi isixazululo saso samanzi sizinzile kakhulu ebusweni bakwa-PH = 2 ~ 12. Amanzi we-Caustic Soda kanye nama-lime angenamphumela omuhle kwizakhiwo zawo, kepha i-alkali ingasheshisa izinga layo lokuchithwa futhi ithuthukise ukubonwa kwe-PIN. Hydroxypropyl methyl cellulose has stability to general salts, but when the concentration of salt solution is high, the viscosity of hydroxypropyl methyl cellulose solution tends to increase.

I-4. Ukugcinwa kwamanzi kwe-hydroxypropyllllllllllllllllluose kuncike kwinani layo lokungezwa, ukubonakala, njll. Izinga lokugcina amanzi ngaphansi kwenani elifanayo lokungezwa liphakeme kunalena ye-methyl cellulose.

6. I-Hydroxypropyllylyl methyl cellulose inokuphikiswa okungcono kwe-enzyme kune-methyl cellulose, futhi amathuba okuwohloka kwe-enzymatic ngesixazululo aphansi kune-methyl cellulose.
