Perforated Porcelain Ball
Classification:
Ceramic filler
Product details
The perforated ceramic ball is a new product developed on the basis of the emotional ceramic ball. It uses the diameter of the sphere as the axis to open the hole, which has the same mechanical strength as the emotional ceramic ball. The chemical stability and thermal stability increase the specific surface area and void ratio, thereby increasing the dispersibility and flux of the material, and reducing the resistance of the system.
Since the product was put on the market, it has been widely used in petroleum. The chemical and natural gas industries replace inert ceramic balls as catalyst support and cover fillers, and are well received by users.
