- Q: Who knows the setting requirements of roofing fire barrier zone?
- curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier?between?two?windows, window sill wall and skirt wall should be sealed by the fire-proof?sealing?material at each floor. I hope I can help you!
- Q: Are fire materials poisonous after burning?
- Refractories burning after the smell of toxic, gases are generally silica, alumina, sulfur oxides and so onRefractory material is not less than 1580 degrees of refractoriness, better thermal shock resistance and chemical erosion, low thermal conductivity and low expansion coefficient of non-metallic materials. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 94% 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, thermal shock resistance is poor. 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, refractory material, good heat shock resistance, resistance to acid slag, widely used.
- Q: Do you know the refractories?
- Acidic material products: these products to quartz (SiO2) as the first phase, SiO2 is an acid oxide, helped named. Brick is representative of the product acid material; semisilica brick, alkali proof brick, acid brick in SiO2 content of 60% to 80%, is a semi acidic material.
- Q: How many types of special refractories are there?
- Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
- Q: How long usually will the A-level fireproof materials prevent the flame?
- The classification of A-level materials is based on GB8624 - 2006 building materials and products combustion performance of grading method. Specific technical requirements are: 1, temperature ≤30 degrees; mass loss rate ≤50%; continuous burning time is 0; 2, the gross calorific value of main components, overall products, external non-substantial components ≤2.0MJ / kg; any internal non-substantial component ≤1.4MJ / kg;
- Q: What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?
- The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.
- Q: What are the fireproofing materials of the external wall included?
- According to the external wall thermal insulation materials, the external insulation materials is in general divided into Class A and Class B. The A class is non-combustible material. The B class is combustible materials. The fire disasters of the CCTV building and Shenyang hotel are both caused by the B level materials. Generally, the A level material will be used, and some prices are even cheaper than the B-grade material. A level is roughly divided into thermal?mortar, phenolic foam Board, rock wool board, foam cement board, and so on. I hope my answer will help you!
- Q: How long is the fire endurance of fire resistant rolling shutter door?
- According to the requirements of Building Regulations 7.5.1 article,the fire endurance of class A fire resistant rolling shutter door should be no less than three hours.
- 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 #......
- Q: How to distinguish the fire resistant level of construction materials?
- There are 3 conditions for building components to reach fire endurance, namely: Loss of ability to support; loss of integrity; loss of fire insulation function. As long as one condition occurs, fire endurance is reached and the time before it is called fire endurance. 1), loss of ability to support: If the specimen bearing capacity and rigidity reduce, section area shrink, collapses or deformation exceeds specified numerical value because it cannot bear the load of original design under flame or high temperature, it loses the ability to support. 2), loss of integrity: It mainly refers to the thin wall separating component(such as stairs, windows,partitions, ceiling, etc.) burst or partially collapse under flame or high temperature, and penetrating?fracture or opening appears, and the reverse side even burn. For example, when the floor is under flame or at high temperature, the flame spread to the upper room, which indicates that the integrity has been damaged. 3), loss of fire insulation function: It mainly refers to that seperating components loses thermal insulation and excessive heat conduction. In experiment, if the average temperature of component unexposed surface exceeds 140 ℃, or if any spot at the unexposed surface exceed the initial temperature of 180 ℃, the component loses fire insulation function.
