Cast stone slab

Because the chemical composition of Penglai basalt is very close to that of cast stone, basalt products with excellent performance and various physical and chemical properties reaching international advanced levels can be produced without adding any auxiliary materials. A single raw material not only simplifies the production process, but also ensures the quality of magma. In ingredient production, although the ratio of main and auxiliary materials has been strictly measured, due to the different particle sizes of the main and auxiliary materials, the large difference in blanking speed during the blanking process causes uneven content of the auxiliary materials in the molten magma, thus causing The chemical composition of magma is unstable. The chemical composition of a single basalt raw material is relatively stable, which fundamentally ensures the quality of magma.

Its products include plates, bricks, pipes and various special-shaped materials. These various specifications of plates, pipes and special-shaped objects are collectively called cast stone products.

There are three types of molding processes for cast stone: melt casting, sintering, and hot direct firing. At present, cast stone products have been widely used in industrial sectors such as building materials, chemicals, metallurgy, and mining. In some parts of many equipment, cast stone is an ideal substitute material for steel, iron, lead, rubber, wood, etc. It has high wear resistance, acid and alkali corrosion resistance that ordinary metals cannot achieve, and has the ability to extend the use of equipment. cycle, reduce maintenance hours, improve production efficiency, reduce product costs and other advantages. Cast stone has been used in anti-corrosion projects for decades and has a history of several decades. It has the characteristics of compact structure, low water absorption, high compressive strength and good wear resistance. It has good corrosion resistance against almost all inorganic acids, organic acids, alkalis, salts, water and organic
