Insulation Brick

Insulation brick belongs to a kind of lightweight insulation refractory material, which is mainly sintered using high quality clay as the main raw material at high temperature. It has the advantages of low bulk density, light bulk density, low thermal conductivity and good heat insulation effect. Insulation brick has a lot of different types, and its density will also vary based on different models. The classification of bulk density of insulation bricks is quite different from that of heavy refractory bricks. The lower the bulk density of insulation bricks, the better the thermal insulation performance, and the aluminum content is basically the same. So everyone who needs insulation bricks can find the right ones in RS Company according to their actual use. Contact us for free price list right now!

The Classification Methods Of Insulation Brick

Insulation bricks, as the main products of kiln insulation, have an extraordinary performance in improving the insulation performance of kiln and saving energy. However, there are so many types of refractory insulation bricks. Therefore, if we want to choose suitable insulation brick, we need to use the physical and chemical specifications such as kiln use characteristics, temperature, refractory temperature and thermal conductivity of heavy refractory bricks as the main reference. The classification methods of insulation bricks mainly include the following types:

Firstly, Operating Temperature. According to the use temperature, insulation brick can be divided into low temperature heat insulation brick (use temperature is 600℃~900℃), medium temperature insulation refractory material (use temperature is 900℃~1200℃) and high temperature insulation refractory material (use temperature is higher than 1200℃).

Secondly, Bulk Density. Insulation brick can be classified into light refractory bricks (bulk density 0.4~1.0g/cm3) and ultra-light refractory bricks (bulk density less than 0.4g/cm3) based on the volume density.

Thirdly, Production Method. There are different ways to manufacture insulation bricks, such as  burning-out addition method, foam method, chemical method and multi-space material method, etc. Besides, insulation brick can also be classified into shaped insulating refractory product and monolithic refractory according to the shape.

Fourthly, Insulation bricks can be classified into LG-MJ-NG-GG-GGR-PG-LGJ grades according to their types, and each grade is selected according to the requirements of its use.

Types Of Insulation Brick

From above descriptions, we can know that insulation bricks have a number of different varieties, such as lightweight clay insulation brick, mullite insulation brick, alumina bubble brick, lightweight silica bricks, etc. Clay insulation bricks are the most widely used among them, both in thermal insulation and in industrial furnaces and thermal pipes, machinery, ceramics, and chemicals.

Lightweight Clay Insulation Brick

Lightweight clay insulation bricks are usually used in the thermal insulation of industrial furnaces according to their functional characteristics, which can reduce the heat loss of the furnace and save power. The operating temperature of them is between 1200℃and 1400℃. The benefits of lightweight clay insulation bricks are outstanding features and low price quotes. So if you are looking for cheap insulation bricks with the best quality, just click here for free quotation.
