The acid-proof refractory bricks produced by Henan Hongtai Refractories have the characteristics of high acid resistance, low water absorption, not easy to be oxidized at room temperature, not easy to be polluted by media, etc. It has an excellent anti-corrosion effect against other acids and alkalis of any concentration at room temperature.

Acid-proof refractory bricks are widely used in petroleum, chemical, fertilizer, pharmaceutical, brewing, dairy products, papermaking, smelting, chemical fiber and electric ferry rooms, laboratories, as well as the lining of towers, pools, tanks, and tanks in power generation, gas and other industries. , and can exert its anti-corrosion ability in workplaces such as underground sewage channels and open ground. It is an ideal product for lining the anti-corrosion and heat preservation of chimneys in thermal power plants.

The acid resistance of acid-proof bricks is mainly manifested in no corrosion, cracks, expansion, peeling, or other phenomena in appearance. Acid-proof tiles are available with or without glaze. Acid-proof refractory bricks mainly include clay bricks and silica bricks.

The clay bricks produced by Henan Hongtai Refractories contain 30% to 46% alumina. It uses refractory clay as the main raw material, with refractoriness of 1580 to 1770 °C and good thermal shock resistance. It is a weakly acid refractory material and is proof to acid slag Corrosive and widely used, it is a class of refractory materials currently produced.

The silica bricks produced by Henan Hongtai Refractories are siliceous products containing more than 93% SiO2. The raw materials used are silica, waste silica bricks, etc. Silica bricks have strong resistance to acid slag erosion but are easily eroded by alkaline slag. Its load softening temperature is very high, which is close to its refractoriness. After repeated calcination, the volume does not shrink or even expand slightly, but its thermal shock resistance is poor. Silica bricks are mainly used in thermal equipment such as coke ovens, glass melting furnaces, and acid steelmaking furnaces.

Due to the expansion of the scale of industrial kilns at present, more and more kiln masonry has transitioned from the selection of clay bricks to the use of silica bricks to exert efficient acid and corrosion resistance.
