Detailed Product Description: | Refractories (Refractory material) of air permeability air permeability allows gas to pass through the material under pressure performance. Since the gas through the permeable material through the pores, the air permeability of the through pores of size, number, configuration and state of the refractory manufacturers, and with the pressing direction during molding of refractory products varies. It and the porosity of a relationship, but no regularity refractory sales, and again, and the porosity is different. Certain refractories (Refractory material), an air permeability is critical indicators, directly affect its anti-corrosion medium, such as slag, molten steel, molten iron and various gases (steam) erosion, oxidation resistance refractory how much , ventilation function. For some materials, such as flame or hot gases for isolation or in direct contact with the slag, the molten metal article, is required to have a very low air permeability; and some functional materials, there must have a certain air permeability. Refractories (Refractory material) directly affected by the permeability of the production process, by controlling the ratio of the particles, forming pressure and firing system can control the permeability of the material. On the air permeability of dense shaped refractory products, in accordance with the national standard GB / T3000-1999 (equivalent to international standards ISO8841: 1991) were measured. Acid refractory castable can resist 800-1200 ℃ acidic medium (nitric acid, hydrochloric acid, sulfuric acid, acetic acid, etc.) corrosion castable refractories (Refractory material), said acid refractory castable. It is based on water glass as binding agent, with an acidic or semi-acidic refractories (Refractory material) as an aggregate and powder, called a small amount of coagulant prepared from. But such is not castable alkali, hot phosphoric acid, hydrofluoric acid and high fatty acid corrosion. Configure such castable rich source of raw materials, low prices, it has been widely used in metallurgy, chemical, petroleum, light industry and other sectors thermal equipment. Refractories wholesale, Tianjin refractories, Refractories shangzhuang provided by Zhengzhou City shangzhuang Refractories Limited. Zhengzhou City shangzhuang Refractories Co.
