Q:Why should graphitic refractory materials be used now that graphite can burn?
In theory, any substance can burn as long as certain temperature is reached. Graphite is turned from diamond under anaerobic condition and at high temperature of 2 000 ~ 3 000 ℃. that is to say, ignition point of graphite (lamellar graphite ) under anaerobic condition will be at least above 3 000 ℃. There are many types of graphite, and their ignition points are also different. Ignition point of pyrolytic graphite is much low. Except for a few cutting-edge areas, fire endurance demand for most areas in daily life (eg. brake pad will add a certain amount of graphite) is under 1000 ℃. Therefore, graphite can be used as refractory material. That is, graphite can both burn and can be used as refractory material, which are not contradictory.
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
Keypoints; 1, curtain wall design must consider the safety requirements, one of which is fire protection design. 2, Generally, fire protection planning between curtain walls should use the method of setting fireproof isolation layer. 3, Two layers of fireproof isolation layer whose thickness should not be less than 100mm respectively on the top edge and lower edge of the material parts of the house. 4, the fireproof isolation layer commonly uses 1.5mm thick galvanized steel sheet as supporting plate, using for shelving fireproof sheet. The 100mm thick cavity between the layers is filled with mineral wool non-combustible materials tightly covered with tinfoil on the surfaces. 5, protective isolation layer should try to reconcile curtain wall beam level and finish floor level, so as to fill non-combustible material and to avoid that a piece of glass acrosses two fire compartments. 6, the beam should be inside 100mm thick fireproof isolation layer to protect the beam and the upper curtain wall plate. 7, when there are open fire function areas like large-scale hotel or restaurant kitchen inside the curtain walls, curtain wall glass in these parts should consider using cesium potassium fireproof glass to improve the fireproof rating in the region. 8, Fireproof setting in the around areas of curtain wall can use the same method of the above fireproof setting between layers. The joint parts of fireproof isolaton layer and main part as well as curtain wall should use fireproof sealant to seal.
Q:What are the meanings of azs, 34% and ec in fused brick?
The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
Q:What are the raw materials of refractory concrete ?
Q:What are the application of old refractory bricks?
It can be used for refractory bricks again, as long as the quality is good. It is much more cost-effective than Bayerite.
Q:What kind of materials can be tested their electrical resistivity in the current refractory industry?
Graphite, Magnesium Oxide, and alumina are all feasible.
Q:The history of refractory material
Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
Go eastward 200 meters from the south gate of cultural square.
Q:What types does refractory floor include?
It includes ecoplates, chipboard,density board, composite board, etc. Wherein ECO-plate is solid wood board, and it is environmetanl and healthy. Its nail-holding ability and flatness is much better than that of chipboard and solid wood particle board. After all it is solid wood board. But we must pay attention to whether the eco-board is produced in the original factory. According to our original factory, the board only produced by Treezo Group and Dede board are the original.
Q:What are the raw materials of refractory?
Refractory is mainly resistant to high temperature and fire. Sic refractories are widely used in refractory. I hope my answer will be helpful to you.
