Light and heavy division of alkali resistant castable refractory

Alkali resistant castable refractory in high temperature, resistance, alkali metal oxide erosion refractory called alkali resistant refractory castable. This kind of castable castable combined with ordinary calcium aluminate cement is similar, it is composed of a mixture of alkali resistant refractory aggregate and powder, binding agent and admixture. According to the environment and use condition of different alkali resistant castable refractory material, light and heavy division, and heavy and can be divided into temperature alkali resistant castable refractory and high temperature alkali resistant refractory castable.

1. Light alkali used in refractory castable ceramic aggregates has alkali materials, porous clay clinker, scrap porcelain material, high strength and expanded perlite. Binders with ordinary calcium aluminates cement. Matrix castable refractory powder may be added to high-silica, at an elevated temperature so as to react with the alkali metal oxides, the glaze layer is formed form a dense layer on its surface, to prevent the melt of alkali metal oxide further penetration and corrosion.
2. Heavy Alkali temperature castable high alumina used in aggregate has guessed, clay guessed so on. Use of calcium aluminate cement binder plus silica microparticles, adding silica microparticles help to improve both the strength of castable combination also helps in use, castable lining impermeable layer formed on the surface, which is characterized by intensity and temperature considerable strength after drying, good alkali corrosion performance.
