Detailed Product Description: | Insulation refractories (Refractory material) in the heat transfer process at the same time two refractory agent present in refractories (Refractory material) stomatal pores in the air along the flow path from the hot face lining of the cold, which also The heat from the hot face lining with cold refractory lining to this heat flow mechanism called convection. However, only refractories (Refractory material), the pores and pore channels are usually small, the air resistance is large, and thus the role of convective heat refractories (Refractory material) within a very small refractories manufacturers, can generally be negligible. Aggregate is used to configure acid refractory castable mainly silica, cast stone, alabaster, andesite, diabase. Several commonly used acid level (measured gravimetric method,%) for raw materials: cast stone 98%, greater than 97 percent silica, clay clinker 92% -96%, greater than 94% andesite. Depending on the selection of the raw material conditions. But the use of silica, quartz must be taken when changing heating polycrystalline refractory sales, changing the process will produce a volume change (expansion), so it is best to replace part Fischer silica brick raw material to make the aggregate, the preparation of this castable The material powder mainly silica powder, cast stone, porcelain powder, high siliceous clay clinker powder, casting powder which is used more acid powder. General Ingredients acid refractory castable composition: Acid refractory aggregate: 60% -70% 30% -40% powder, plus a density of sodium silicate solution 1.38-1.42g / cm3 of 13-16%, with fluorosilicone When sodium as the hardening accelerator in an amount of 10-12% water glass solution quality.
