White corundum Of course, it can be made into acid and alkali resistant castable
White corundum sand has high temperature resistance, good thermal stability, acid and alkali corrosion resistance, so white corundum is widely used in the field of refractories, but some problems should be paid attention to when using.
1. The stirred water temperature should be appropriate, not higher than 25 °C in summer, and the water temperature should be kept between 30 °C ~ 50 °C in winter.
2. White corundum sand should not be exposed to the sun during use, and should be shaded.
3. The place of use can be in a covered workshop and so on.
The temperature is too high or too low will have some impact on the acid and alkali resistance of the white corundum sand castable, so the above three problems need to be paid attention to during construction to improve the performance of the product and the construction effect.
