If you’ve any enquiries, please don’t hesitate to let us know.

Q:Manganese steel belongs to refractories: NO!

Q:What is the principal part of silicious refractory material: Silicon nitride and aluminite powder as well as dextrin

Q:What are the materials of white firebricks?: They are made of baked refractory materials with pale yellow and a little brown on the surface and very cheap. They are mainly used to pile up smelting furnace and can withstand high temperature from 580 degrees Celsius to 770 degrees Celsius. While the firebricks, also called refractory bricks by others, have a certain size and shape. They can be classified according to manufacturing process, namely, the unburned bricks, burnt bricks and electrically fused bricks. Also they can be divided into common bricks, standard bricks and specific bricks according to different size and shape.

Q:What are the requirements when producing fireproof materials by kaolin?: Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.

Q:What's the fire endurance of fire windows?: Fire endurance of fire doors and fire windows stipulated by the fire prevention norm: Fire endurance of A class fire door or fire window is 1.2h rather than 1.5h, and fire endurance of B class fire door or fire window is 0.9h rather than 1.0h. Fire prevention code doesn't explicitly state that the fire door has thermal insulation function, so it can definitely be interpreted that the fire door only has fire integrity. For the fire door without heat-shielding performance, at certain distance from the unexposed surface, it has strong thermal radiation and is easy to hurt people. For the A class thermal insulating fire door, its fire integrity is 0.1h shorter than that of the corresponding fire door stipulated in the specification, but its heat-shielding performance and integrality is improved. All in all, compared with the specification that the fire integrity of the A class fire door should be 0.6h, it has much more improved its performance.

Q:what's the fireproof levels of fireproof and thermal inuslation matertial?: 1, organic materials: B level material is flammable, B1 level material is flame retardant. 2, inorganic materials: Grade A flame-resistant materials are divided into three classes and two kinds of materials.

Q:Does anyone know about the A-level fireproof materials?: A1-level fireproof materials include: 1. inorganic materials: glass wool, rock wool, foam glass,etc. 2. organic materials: phenolic foam insulation composite board. I hope my answer can help you.

Q:Who knows the new fireproof and thermal inuslation matertial?: New fireproof and thermal inuslation matertial: foam concrete building blocks brick. The foam concrete building blocks brick is a new fireproof and thermal insulation material, with distinct advantages compared with the organic insulation material . Foam concrete can be used as wall materials, and it has a good self-insulation properties, so there is no problem of dropping off the outer insulating layer. A small part takes external wall exterior insulation, with mostly anchoring or dry hanging, which are not easy to fall off. Very few uses paste. Since the foam concrete and wall materials are of the same nature and strong adhesive, so it is also not easy to fall off.

Q:What is the particle size of boron carbide for refractories?: 0.3-0.5% is OK, but also with other additives, such as aluminum powder, silicon powder, magnesium alloy powder and so on. To achieve good results.
