IMethyl cellulose ether

1.Iimpawu:

(1).Ukugcinwa kwamanzi: UkusukelaIMethyl cellulose etherimveliso inokufunxa isixa esikhulu samanzi, inokugcina amanzi kudaka kunye negypsum.

(2).Ukugcinwa kobume: isisombululo saso samanzi sineempawu ezikhethekileyo ze-viscoelastic, ezinokugcina imilo yeemveliso ze-ceramic.

(3).Ukuthambisa: I-MC inokunciphisa i-coefficient ye-friction kunye nokuphucula ukusebenza kwe-lubricating yee-ceramic kunye neemveliso zekhonkrithi.

(4).Uzinzo lwexabiso le-PH: i-viscosity yesisombululo samanzi ayinakuchaphazeleka nge-asidi okanye i-alkali.Isisombululo sayo samanzi sihlala sizinzile kuluhlu olubanzi lwe-pH, ngokubanzi phakathi kwe-3.0 kunye ne-11.0.

(5).Iimpawu zokwenza ifilimu: I-MC inokwenza ifilimu eqinile, eguquguqukayo kunye necacileyo kunye nokuchasana kweoli.

2.Ifomula yemolekyuli:

N: iqondo lepolymerization;R: -H, -CH3 okanye CH2CHOHCH3

3.IiPropati zePhysical and Chemical

Indlela yokuphelisa:

Qala ukutshisa amanzi kwi-80-90 ° C, ngokukhawuleza ungeze i-MC phantsi kokuvuselela okuqhubekayo, ulinde ukuba ukushisa kwehle, emva koko upholile ukwenza isisombululo esifana namanzi.Okanye wongeza isinye kwisithathu ukuya kwisibini kwisithathu samanzi afunekayo kuqala, ukushisa kwi-80-90 ° C, ngokukhawuleza ungeze i-MC phantsi kokuvuselela rhoqo, emva kokwandisa, yongeza amanzi abandayo asele, kwaye upholise.
