Heat-Insulating Brick
To better match the thermal equipment that requires high strength, refractory and thermal insulation materials, Xinghui managed to develop and manufacture A1, A2, B1, B2 and other types of diatomite heat insulating bricks to Japanese standards. Through authentication, the physical and chemical indexes of these refractory bricks completely comply with the JIS R2611-1976 standards. In addition, they obtained perfect effects during use in the Japan-made electrolytic bathes and anode baking from a domestic aluminum plant, as well as in the second stage construction of Baosteel.
Applications
Our heat insulating bricks made from diatomite are mainly designed for matching with various world famous thermal equipment. They are new and ideal heat insulating materials, normally used in all kinds of thermal treating furnaces at a temperature of less than 1000℃.
Features
1. This diatomite brick is an efficient heat insulation material, mainly made from high quality diatomaceous earth with addition of bonding agents.
2. It is especially suitable for non-ferrous metal smelting furnaces, calcinators and other thermal equipment.
3. The heat insulating brick can effectively save energy and prolong furnace's service life.
Specifications
Our diatomite heat insulating bricks are made to customers' size or national standard size.
