Activated calcium carbonate powder QT-7/QT-8+H

Activated calcium carbonate powder QT-7/QT-8+H

QT-7/QT-8+H active calcium series can be customized according to customer needs: products with different activation degrees, whiteness and fineness with activation degrees of 30%-99%. This series of products uses ordinary calcium carbonate ultrafine powder as raw material, adds water-based or oily additives for surface treatment, and is surface treated by surface activation equipment. It has low moisture, good dispersibility, and does not produce agglomeration. Combined with the formula and production process of downstream manufacturers, it can effectively enhance the performance advantages of downstream products and reduce the overall production cost of downstream.
