Methyl cellulose ether

1.Likarolo:

(1). Ho boloka metsi: Ho tlohaMethyl cellulose ethersehlahisoa se ka monya metsi a mangata, se ka boloka metsi ka seretse le gypsum.

(2). Ho boloka sebopeho: tharollo ea eona ea metsi e na le thepa e khethehileng ea viscoelastic, e ka bolokang sebōpeho sa lihlahisoa tsa ceramic.

(3). Lubricity: MC e ka fokotsa coefficient ea likhohlano le ho ntlafatsa ts'ebetso ea ho tlotsa ea lihlahisoa tsa ceramic le konkreite.

(4). PH value stability: viscosity ea aqueous solution ha e amehe haholo ke asiti kapa alkali. Tharollo ea eona ea metsi e lula e tsitsitse ho feta mefuta e mengata ea pH, hangata e pakeng tsa 3.0 le 11.0.

(5). Thepa ea ho etsa lifilimi: MC e ka etsa filimi e tiileng, e tenyetsehang le e pepeneneng e nang le khanyetso e ntle ea oli.

2. Foromo ea molek'hule:

N: tekanyo ea polymerization;R: -H, -CH3 kapa CH2CHOHCH3

3.Thepa ea 'Mele le ea Lik'hemik'hale

Mokhoa oa ho hlakola:

Qala ho futhumatsa metsi ho 80-90 ° C, butle-butle eketsa MC tlas'a ho hlohlelletsa ho tsoelang pele, emela hore mocheso o theohe, ebe o pholile ho etsa tharollo e tšoanang ea metsi. Kapa eketsa karolo ea boraro ho tse peli ho tse peli ho tse tharo tsa metsi a hlokahalang pele, mocheso ho 80-90 ° C, butle-butle eketsa MC tlas'a tšusumetso e sa khaotseng, ka mor'a ho atolosa, eketsa metsi a batang a setseng, 'me u pholile fatše.
