Insulation Brick
MOQ：5 tons
Description
Insulation brick for fire resistance is a type of high performance insulating material that frequently contains alumina, silicate, and other common materials. It has the following important characteristics, making it one of the more often used thermal insulation materials: low density, low thermal conductivity, high temperature resistance, and effective heat insulation. Most of the time, it can be used for extended periods of time in high-temperature situations above 1000°C. By reducing the cost of the foundation, the cross-section of the frame, and the requirement for reinforced concrete, insulation firebrick can significantly reduce the overall cost of the construction.
Features
A lightweight insulation material with specific applications, insulation brick is employed mostly in structures and machinery that need to have specified fire prevention and thermal insulation performance. Its benefits primarily consist of the following:
Good thermal insulation performance: The lightweight insulation fire brick for refractory resistance can still provide good thermal insulation effects in high temperature conditions due to the low heat conduction coefficient and high pore rate, effectively minimizing energy waste.
Good refractory resistance: Light-resistant warming tiles can tolerate hot barbecues, have a good refractory capacity, and can effectively put out flames and minimize fire damage.
Simple to build: Light-resistant bricks are light and tiny, easy to carry, and inexpensive to install compared to traditional heavy-quality refractory materials, which can significantly lower the difficulty and cost of construction.
No pollution and environmental protection: Natural minerals are used as the primary raw materials to create the light insulating brick for refractory resistance. It complies with current energy conservation and environmental protection standards and doesn't include any dangerous elements.
Due to its high pore rate, light-quality insulation brick for fire resistance have an excellent sound absorption effect, can effectively separate sounds, and may increase the comfort of the living environment. It has a certain sound insulation capability.
Application
Insulation brick can be used for the back insulation of hot surface refractory lining or other refractory materials, in addition to being used as a refractory lining or insulation material for petroleum and chemical kilns.
