Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?

Polystyrene foam plastic can not be used as fireproofing material; polystyrene foam plastic is made up of polystyrene resin as main component, foaming?agent and other additives. It is a buffer material which is most widely used[1]. It is closed hole structure, so it has low water-absorbing quality and excellent water resistance; low density, about 0.015 ~0.03; good mechanical strength, excellent buffer?performance; good machinability, easy to be moulded; good dyeing property, thermal adaptability and anti-radiation; high dimensional accuracy, uniform structure. Therefore, it has a large share in external wall thermal insulation. But it will emit polluted styrene gas when burning. It is a kind of class B material in construction.

Q:What does the function of SiC for refractories?

As inorganic material, the silicon carbide has the characteristics of high temperature resistance and good anti-wear ability. The sisic products can be used at the blast furnace ceramics. For the unburned?brick, such as alumina-magnesite carbon brick, the silicon carbide can also be added as an antioxidant.

Q:How many kinds of A-level fireproof and thermal insulation materials are there?

1. foam insulation board refers to foam ceramic insulation panels whose raw material is inorganic ceramic which is calcinated at high temperature with abbreviation of ceramic insulation board 2.Composite cement foam insulation board is a hydrophobic lightweight closed-cell insulation board whose main materials are cement, fly Ash, and silica fume which has been foamed, cured and cut. 3. aerated concrete panel is a lightweight concrete panel which has been autoclaved with lightweight materials, siliceous material and gas former as its raw materials. 4. rock wool panel, with natural igneous rock wool as its main raw material, is a cotton which is melted in high temperature by centrifugation and is pasted by thermosetting resin.

Q:What are the application of old refractory bricks?

It can still be used as refractory bricks or refractory. The quality of auxiliary material is not as good as bauxite.

Q:what kind of refractories is used to make the industrial silicon furnace mouth long life?

Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.

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

Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.

Q:How to hang the suspended brick in the refractory masonry?

First you can weld the metal fastener of the suspended brick and then hang up the brick.

Q:Fire resistance and evaluation of refractory for casting

The refractory degree of refractory material at high temperature is called refractoriness. Refractory products all contain substances from fusible sintering action, the melt crystal as unlike at a fixed temperature, but the temperature in a wide range. At a lower temperature, a small amount of melt is formed, and as the temperature increases, the amount of the melt increases, and the product gradually softens. Refractoriness and melting point (crystal) are different concepts.

Q:How many grades of fire?rating are there for interior decoration materials?

It can be divided into construction classification and fire resistance rating. Fire prevention for buildings. Fire prevention measures should be taken in the architectural design to prevent fires and reduce fire hazards to life and property. Building fire protection includes two aspects: fire prevention before fire disaster and measures in fire disaster, among which the former is mainly to confirm the fire resistant rating and fire-resistant structure.

Q:Can anyone tell me which materials are fire-proof high temperature resistant material?

Fireproof high temperature resistant material is the synthetic material with fireproofing properties, or the material itself is high temperature resistant, heat-resistant, flame-retardant material. Fireproof materials are mainly used for construction with a variety of forms, which plays an absolute role in modern fire protection. The commonly used fireproof materials including fireproof panels, fire doors, fireproof glass, fire retardant coating and fireproof bag, etc.
