How to use the lightweight insulation castable? Are you using it?

The lightweight insulation castable is made of aluminate cement, high alumina fines, ceramsite and various additives. The product is small in size, high in compressive strength, resistant to acid and acid gas corrosion. Insulation, insulation, low water absorption and easy construction are ideal products for the construction of alkaline parts at high temperatures. Good workability, strong adhesion, long initial setting time and long construction time, fast strength growth, strong impermeability, no acid treatment, easy to ensure the compactness and fullness of masonry mortar joints, can significantly improve the chimney lining The airtightness and integrity of the wall and the corrosion resistance of the lining are ideal cementing materials for high temperature chimneys, high temperature flue and duct lining. It can also be used for acid resistance tanks, tanks, etc. in petroleum, chemical, nonferrous metallurgy and other industries. engineering.

Lightweight insulation castables tips:

First clean the mold and pouring contact surface, add water to the castable to make the water content reach 42-45%, stir evenly, then release the mold after 24 hours of pouring, the castable is ignited and baked after 2-3 days of natural curing. Bake and attach a plastic film. The castable contains a large amount of bound water and free water. The baking should be controlled to prevent cracking and spalling caused by sudden heating, especially at 120 ° C, 350 ° C and 600 ° C.

 

Amorphous lightweight insulation refractories have been widely used by most users, and the application of insulating refractories has progressed to amorphous lightweight insulation refractories. Due to its small bulk density and low thermal conductivity, it can reduce the self-weight of the equipment, has good thermal insulation performance, makes the furnace temperature uniform, saves energy, has high refractoriness, strong comprehensive performance, good anti-flaking property, long service life and can be repaired at will. Process a variety of shapes or integral linings. The structure is simple and the cost is low. Now it has been widely used in industrial furnaces and thermal equipment in metallurgy, machinery, electric power, chemical, petroleum and other industries, saving more than 20% energy than ordinary refractory materials.
