What is the difference between insulation brick and refractory brick

Seven characteristics of magnesia carbon brick manufacturers' insulation bricks:

Heat preservation and insulation: effectively reduce energy consumption.

Fire protection: Class A if it reaches the national standard.

Clean and environmentally friendly: will not cause secondary air pollution.

Light weight: It weighs only about 1.4 kg per square meter, which reduces the load of the building.

Simple production: completely break through the traditional craftsmanship and greatly shorten the construction period.

Beautiful: It can be adjusted into various colors, suitable for surface installation.

Durable: long service life.

Compared with other products

Compared with the traditional "galvanized sheet + insulation cotton" air duct:

1. It can reduce the project cost by more than 20%

2. The construction period can be shortened by 3~5 times

3. Noise reduction can be 5~10 decibels

4. No condensed water is generated, and the sealing is better

5. Wider application range -196℃~＋200℃

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

7. There is no smoke and no toxic gas release when burning in fire

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

9. It can reduce the weight of the building by 20%

10. The service life is three times longer than that.

High-alumina bricks, clay bricks, high-quality silica bricks and other refractory products are widely used in metallurgy, building materials (cement glass), non-ferrous metal smelting, petroleum, chemical, electric power, machinery manufacturing and other industries.
