- Q: What are unshaped fire-resisitance materials?
- Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
- 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: How to count the construction costs of refractories?
- In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
- Q: who knows the uses of refratories?
- Physical properties of refractories include structural properties, thermal properties, mechanical properties, usability and operation. structural properties of refractories include porosity, bulk density, water absorption, air permeability, pore size distribution. Refractory thermal properties include thermal conductivity, thermal expansion coefficiency, specific heat, heat capacity, thermal diffusivity, thermal emissivity. Mechanical properties of refractories include compression strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep property, adhesive strength, modulus of elasticity. Refractories are used in various fields of steel, nonferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, power, military and other fields of national economy. They are essential materials that ensures the production run and technological development of the above industries, and play an important role in promoting the developemnt of high temperature industrial production. the usability of refractories include refractoriness, softening temperature under a fixed load, linear?change?on?reheating,thermal shock resistant performance,slag resistance, acid resistance, alkali resistance, hydration resistance, carbon monoxide resistance, conductivity, oxidation resistance.
- Q: what's the fire endurance of fireproof?panel?
- non-asbestos calcium silicate board, fireproof?panel partition will excced over 4 hours, two single 75 keel. 12 mm fireproofing calcium?silicate?board partition, through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 4 hours.
- Q: What is the concept of lightweight refractory material?
- Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
- Q: Does refractory belong to stone, building materials or other?
- Refractories belong to organic non-metallic materials, stone and construction materials. After it is used in building. Just for your reference.
- Q: Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
- The texture should be designed according to the British relevant BS standard; crosslinked polyethylene or ethylene propylene rubber under 6600V to 19000 / 33000V is not necessarily ceramic silicone. The rated voltages of a small amount of smoke and corrosive gases from 3800 & # 47 when the BS 7835-2000 is affected by fire.
- 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 are the uses of refractory materials of glass furnace?
- crown--high-purity silica bricks; wall--melting end 41# fused zirconia corundum bricks with no shrinkages(41% of zirconium, similarly hereinafter), cooling end 33# fused zirconia corundum bricks with no shrinkages; bottom--33# fused zirconia corundum bricks(with shrinkages); breastwork--33# fused zirconia corundum bricks(with shrinkages); port--33# fused zirconia corundum bricks(with shrinkages); regenerator chamber--the upper part is for magnesite-chrome bricks, the bottom part is for high-duty fireclay bricks; checker--the upper part is for high purity magnesia bricks, and the bottom part is for magnesite-chrome bricks; flue--clay bricks. This is the best configuration. If the funds are limited, the configuration can be lowered, for example, the wall will be changed to 38 #......
