I-Methyl cellulose ether

1.Izici:

(1). Ukugcinwa kwamanzi: KusukelaI-Methyl cellulose etherumkhiqizo ungamunca inani elikhulu lamanzi, ungagcina kahle amanzi odaka kanye ne-gypsum.

(2). Ukugcinwa komumo: isisombululo saso samanzi sinezindawo ezikhethekile ze-viscoelastic, ezingagcina ukuma kwemikhiqizo ye-ceramic.

(3). I-Lubricity: I-MC inganciphisa i-coefficient yokungqubuzana futhi ithuthukise ukusebenza kokugcoba kwemikhiqizo ye-ceramic kanye ne-concrete.

(4). Ukuqina kwenani le-PH: i-viscosity yesisombululo esinamanzi ayithintwa kancane yi-asidi noma i-alkali. Isixazululo saso esinamanzi sihlala sizinzile phezu kwebanga elibanzi le-pH, ngokuvamile eliphakathi kuka-3.0 no-11.0.

(5). Izakhiwo zokwakha ifilimu: I-MC ingakha ifilimu eqinile, eguquguqukayo futhi esobala enokumelana okuhle nowoyela.

2.Ifomula yemolekyuli:

N: idigri ye-polymerization;R: -H, -CH3 noma CH2CHOHCH3

3.Izakhiwo Zemvelo Nezamakhemikhali

Indlela yokuqeda:

Okokuqala ukushisa amanzi ku-80-90 ° C, kancane kancane wengeze i-MC ngaphansi kokuvuselela okuqhubekayo, ulinde ukushisa kwehle, bese upholisa ukuze wenze isisombululo se-aqueous uniform. Noma engeza ingxenye eyodwa kwezintathu kuya kwezingxenye ezimbili kwezintathu zamanzi adingekayo kuqala, ukushisa ku-80-90 ° C, kancane kancane wengeze i-MC ngaphansi kokuvuselela njalo, ngemva kokwandisa, engeza amanzi abandayo asele, bese upholisa.
