insulation brick
Date:2017-07-19 09:52 | From:Zhengzhou Sunrise Refractory | Author:admin
Insulation brick seven features:
Insulation: effectively reduce energy consumption.
Fire: meet the national standard or A level.
Clean, environmental protection: will not cause secondary pollution of the air.
Light weight: only about 1.4 kg per square meter, to reduce the load on the building.
Production simple: completely break through the traditional process, greatly shorten the construction period.
Beautiful: can be modulated into a variety of colors, suitable for Ming.
Durable: long service life.
Compared with other products
Compared to the traditional "galvanized sheet + insulation cotton" duct:
1, can reduce the project cost more than 20%
2, can shorten the duration of 3 to 5 times
3, can be reduced noise 5 to 10 dB
4, no condensate generated, better sealing
5, the use of a wider range -196 ℃ ~ +200 ℃
6, insulation and energy efficiency and then increased by 10% to 15%
7, when the fire burning smoke and no toxic gas release
8, embossed aluminum foil looks more smooth, beautiful
9, can reduce the building load bearing 20%
10, the service life increased by three times.
High alumina brick, clay brick, high quality silica brick and other refractory products, widely used in metallurgy, building materials (cement glass), nonferrous metal smelting, petroleum, chemical, power, machinery manufacturing and other industries.
