Insulating Brick (JM 26)

Detailed Product Description

The photo shows JM insulating brick.  The type is JM26.

DOUBLE EGRET is the specialized manufacturer and exporter of insulation and refractory material in north of China with more than 10 years' history. Our brand CCE WOOL is well known in the world, enjoying good maket in Europe, America, Southeast Asia and Mid East.

CCE WOOL insulating brick has low density high porosity, low thermal conductivity, and can keep furnace wall low radiation and depress the charges of fuels. We mainly export insulating brick to UK, USA, ITALY, JAPAN etc.

CHARACTERISTIC:

 Low thermal conductivity,excellent thermal insulation.

Low thermal capacity excellent conserve energy in batchoperation kiln

Low impurity. The higher aluminumcontent made it still to maintain the good performance under thereducing atmosphere.

Precise outlook size. Speeds up the masonry and building speed, thebrickwork joint thin also neat is consistent. Guaranteed masonry andbuilding body intensity high, the stability is high.

APPLICATION:

 glass industries                             iron & steel industries

ceramics industries                        non-ferrous metals industries

electrolytic Aluminum industries      power generation industries

Heat surface fireproof lining             other fire-proof materials back lining thermal insulation
