What should be noted when using white corundum as an acid and alkali resistant casting material
Release Date:2021-04-01 07:04

White corundum sand has the properties of high temperature resistance, good thermal stability, and acid alkali corrosion resistance. Therefore, the application of white corundum in the field of refractory materials is very extensive, but some issues should be noted when using it.

1. The temperature of the stirring water should be appropriate, not higher than 25 ℃ in summer, and the water temperature in winter should be maintained between 30 ℃ and 50 ℃.

2. During the use of white corundum, it should not be exposed to direct sunlight and should be treated with shading.

3. The place of use can be in a workshop with a roof, etc.

Both high and low temperatures can have some impact on the acid and alkali resistance of white corundum castables, so it is necessary to pay attention to the above three issues during construction to improve product performance and construction effectiveness.
