Q:What are the applications of refractory busway?

Fire-resistant busway has excellent insulation property, and it can not only be used continuously in a normal environment, but also be used continuously when catching fire for more than one hour. It can be used in high buildings and important facilities in replace of fire-resistant cables to transmit and distribute electricity.

Q:I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad

You don't give a cent to this question, no one will answer it

Q:What do refractory materials include?

It is so difficult.

Q:How can refractory material of the electric furnace be used for longer.

Do not exceed the temperature, do not exceed the limits of use in order to achieve the best performance and the longest service life

Q:What type of firebrick does TZ-3 represent?

Z represents a straight brick, T stands for common brick, common straight standard brick, -3 represents the length, and the specification is 230 * 114 * 65 (mm).

Q:what is the Specifications Grading for Fireproof rubber insulation materials ?

At present, China Building Materials has two grading criteria for combustion performance. "Combustion Performance Classification Method of Building Materials" and "Combustion Performance Classification Method of Building Materials and Products" (GB8624-2006). Among them, one of the major changes of GB8624-2006 and GB8624-1997 is to divide the material combustion performance grading from homogenous material)Class A (composite sandwich material), B1, B2 and B3 level five minutes as A1, A2, B, C, D, E, F seven levels.

Q:How to understand qualitative and qualitative refractory materials?

Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.

Q:How long is the fire-resistant time of fireproof wooden door?

fire endurance class A (1.5 hours), class B (1.0 hours), class C (0.5 hours).
