Q: What is the main constituent of refractory brick?: Primarily magnesium oxide and sodium silicate as binder.

Q: How much modulus is used as refractories material of sodium silicate.: Storage and use are very convenient, especially for mechanized and the evenly refractory material and the sodium silicatemodulus is generally...2. transportation. The appearance of product is pure white. Instant powdered sodium silicate, also known as instant sodium metasilicate.4 to 3, in powder form, automation. in the range of 3, hydrated sodium silicate

Q: Who knows how to divide the building fire grade and fire resistance grade?: I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.

Q: Fire rating of decoration materials: code for fire protection design of buildings

Q: What do refractory materials include?: It is so difficult.

Q: What is the acceptance standard of refractory?: It depends on the variety of materials. In general the main test items include chemical composition, refractoriness, refractoriness under load, creep, volume density, linear change, strength, slag resistance, thermal conductivity and thermal expansion. If it is shaped products, it is required to inspect the size deviation and whether it has edge. Detection method accords with the relevant national standards and there are lots of them. You can refer to the standard compilation.

Q: Detailed description of magnesia dolomite refractory material?: The CaO of magnesia dolomite refractory is beneficial to the purification of molten steel. In the aspect of smelting clean steel, magnesia dolomite refractory also has good dephosphorization and desulfurization effect.

Q: Who can tell me the properties and classification of insulating refractories?: Burn out addition method. This method is sawdust or combustible additives into mud. Sublimation mixing and extrusion method, semi dry or slurry casting moulding, drying and sintering. Combustible or sublimation additives in the firing process of burned, leaving the empty hole, become insulating refractory products.

Q: what's the materials of fireproof?housing?: there are mainly several fireproofing levels, it is divided into flame retardant and non-combustible! at present t the main fireproofing materials on the market are made from rock wool board! it is incombustible?material, of course, the price is relatively high. Other common materials are fire?retardant foam.
