Q:Can anyone tell me the requirements of the refractory masonry??
Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.
Q:What is acid refractory material?
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used. Neutral refractory is mainly composed of alumina, chromium oxide or carbon.
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
Hello. 1. Gaps between the curtain walls and floors of all tier and partitions outer edge should be sealed with non-combustible material or flame retardant materials. Filling material can be rock wool or mineral wool, whose thickness should be not less than 100mm and should meet the designed fire endurance requirements, forming fire and smoke prevention areas between floors and rooms. Fireproof layer should use galvanized steel bearing with thickness of not less than 1. 5mm, and should not use aluminum plate. Gaps between bearing plate and main structure, curtain wall structure and the bearing plate should be sealed by fireproof sealant; fireproof sealant should has fireproof inspection reports granted by statutory testing organizations. 2. When building designs requiring transparent effect of fire compartment and separation, monolithic fire-resistant glass or hollow and laminated fire-resistant glass nade by monolithic fire-resistant glass can be adopted. 3. Windowsills-free curtain walls, incombustible entities skirt wall or fireproof glass wall whose fire endurance is not less tan 1.0 hour and height is not less than 0.8m should be set on the outer edge of each floor. The thickness of reinforced concrete floor or height of the side beams should be counted when calculating the height of the skirt wall. 4. Fire protection layer should not contact directly with the glass curtain wall, and the side towards the glass of fireproof materials should be covered with the decorative material. 5. Glass units of the same curtain wall should not cross two fire compartments.
