The low cement castable price is reasonable, the production process and the burden requirement are relatively strict, many factors can affect its performance. The following small make up to introduce the characteristics of low cement castable, and what factors affect the performance of low cement castable.
This series of refractory castable is a kind of refractory material, which can meet the requirements of high temperature kiln. It has the characteristics of high density, high strength and so on. Low cement castable price preferential, welcome to consult the purchase.
Characteristics of low cement castable:
1. The outstanding feature of low cement refractory castable is density and high strength, which brings benefits for use. But brought trouble to bake, bake namely improper, easy occurrence flaking or blast crack phenomenon. Therefore, it is very important to make a reasonable oven curve and to use excellent explosion-proof admixture, so as to make refractory castable molding weight of water.
2. Low cement castable is a kind of high technology refractory developed on ordinary refractory castable by using rheological principle, most compact packing theory and ultrafine powder technology. It has the characteristics of low porosity, small pore size, high density, good volume stability, high strength and small amount of water. And overcome the ordinary castable strength at 800 ~ 1200℃ significantly decreased characteristics.
3. Different from ordinary refractory castable is low cement, ultra-low cement castable is to use and castable main material chemical composition is the same, or similar to the ultrafine powder to replace part or most of calcium aluminate cement, while adding trace dispersant (water reducer) and a certain amount of delayed coagulant. The cement-free castable is completely made of ultrafine powder or oxide sol.
