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
