General information of Insulating Brick

Insulating firebricks are classified under tempera-ture between 1100C to 1700C, manufactured from high purity alumina clay.

Insulating fire bricks are made from high purity alumina and low iron content raw materials. The insulating fire bricks are produced by mixing, casting or extruding, drying, sintering and grinding. Our insulating fire bricks GJM23 temperature is 1260(2300). A variety of type could be done according to customer’s request.

To make our firebricks more energy and cost effective, we have different manufacturing methods for our insulating fire bricks casting and extruding method.

For insulating fire bricks GJM23,we choose the casting methord.The casting insulating fire bricks offering the lowest density, the lowest thermal conductivity for the application above 1000.

 

Application of Insulation brick

Insulating firebricks can be used as a hot face lining directly exposed to the heat or as a backup insulation layerin iron and steel mills, non-ferrous foundries, petrochemical, ceramic, glass.

 

Features of Insulation brick

◆Light weight and low thermal conductivity
◆Low heat storage
◆Low iron and impurities
◆High thermal shock resistance

- Inquire about price/MOQ

Q:What is the difference between the production line of foamed cement insulation bricks and the self thermal insulation block production line?
I still feel that the special is better, specializing in the production of a product, at least quality and after-sale protection!
Q:Clay insulation bricks insulation, brick and ordinary clay brick, fireclay, brick distinction, and its use? Thank you
The insulation brick integrates the excellent heat preservation effect into the wall while building the wall. Low thermal conductivity, high strength, durable, lightweight, simple construction, easy handling, economy, green environmental protection, sound insulation, fire protection etc..
Q:What is the price of fireproof insulation material?
Fire insulation materials are various, different specifications, grades of prices are different, according to market rules, there will be fluctuation, the most commonly used are insulation rock wool, insulation board, insulation bricks, fire blocking materials.
Q:The structural specification does not indicate that masonry needs insulation bricks. Is it necessary to use insulation bricks?
Look at the exterior wall insulation design, construction practices and related requirements
Q:What is the price of concrete self insulation bricks
Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
Q:What are the insulation materials for heating buried pipelines?
The thickness of insulation layer should be reasonable and economical. If the insulation layer is too thin, the heat loss will be increased; the insulation layer is too thick, and the surface area of the radiator will be increased, and the heat loss will also be increased. In general the design, determine the thickness of the insulation layer according to the factors of insulation material properties, heat medium temperature, often used for 40~50 mm thickness.
Q:How to reinforce a porous brick foundation?
The basic type method is changed from independent basis to strip foundation, from strip foundation to raft foundation and pile foundation, from brick to concrete strip foundation.
Q:Insulation brick should pay attention to external walls?
Before the tile is adhered, the water spraying device is applied to spray the wet water on the adhered base layer so as not to flow better.
Q:Is the building built of cement hollow board safe?
According to the use of building housing, before the use of cement hollow plate, it is necessary to predict the bearing capacity of housing, if more than the cement hollow plate bearing indicators, it is not available, it is unsafe;
Q:What is the exterior wall insulation material made of graphite?
Graphite polystyrene (SEPS) containing graphite particles special, can be like a mirror which contains thermal radiation, and can greatly enhance the heat insulation performance of the infrared absorption, thereby reducing the heat loss of housing. Its insulation capacity is at least 30% higher than the average EPS, helping to increase energy efficiency and reduce carbon dioxide emissions.
