Where is the difference between the insulating brick and the firebrick

Date:2018-05-03 Author: Click:

Seven characteristics of magnesia carbon brick factory insulation brick:

Heat insulation and insulation: effectively reduce energy consumption.

Fire prevention: reach national standard or class a.

Clean and environmental protection will not cause the two pollution of the air.

Light weight: only 1.4 kg per square metre, reduce building load.

Production is simple: completely break through the traditional technology, greatly shorten the construction cycle.

Beautiful: can be modulated into various colors, suitable for Ming Zhuang.

Durable: long service life.

Compare with other products

Compared to the traditional "galvanized sheet + insulation cotton" wind pipe:

1, the cost of the project can be reduced by more than 20%

2. 3~5 times of shrinkage period

3. The 5~10 decibels can be muffled and de-noising

4. No condensate is produced, and the seal is better.

5. The range of use is more wide -- nineteen sixty - + 200 degrees centigrade

6. The effect of heat preservation and energy saving is improved by 10%~15%

7. No smoke and no toxic gas release in the case of fire

8. The appearance of the embossed aluminum foil is more smooth and beautiful

9, can reduce the weight of building 20%

10, the service life is three times higher than that of the other.
