No chalking and no performance

High strength and wide range of use

Convenient, healthy and eco-friendly

Good quality control, high capacity

Brief Description

Inorganic thermal insulating board series is a new type of refractory insulation material processed by large automatic continuous production line using pure inorganic materials. The working temperature is from 900℃ to 1300℃, and it can be used for the back lining of various industrial furnaces, which is a good choice for the heat insulation of furnaces. The bulk density of 0.3〜0.6 g/cm3 can be produced, which fills the gap in China. At 350 degrees, the thermal conductivity can be controlled within the range of 0.11 〜0.13W/(m.K), and the strength can be controlled within the range of 1-2MPa, and the maximum processing size can be 1*2m.

Advantages

The composition structure has nano-micro porosity, which makes the product have good thermal insulation performance.

The permanent linear change rate after heating does not exceed 0.5% within the specified working temperature, and does not shrink in long-term use. The heating permanent line change rate of ordinary insulation board reaches 2%-3%, and the shrinkage is more than 4 times that of inorganic insulation board.

Completely fiber-free, organic-free, all inorganic materials, no chalking and no performance degradation with long-term.

Compared with ordinary thermal insulation board, it has better cold crushing strength, which is more than 3 times, and also has good strength after burning. It can be used in high temperature for a long time, which is safer and wider range of use.
