Q:how to divided the external wall thermal insulation materials fire rating
Level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion source is removed, the combustion will stop immediately. Level B2: Combustible building materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: Combustible building materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high.
Q:What are included in fireproofing materials?
There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire retardant material and its products, textile, fire retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof sealing material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of toxic gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.
Q:Who know what kind of fire shutter fire rating are there?
The fire resistance limit of high steel structure reduces the loss of fire, achieves remarkable results. The specification is mae in order to unify the application technical requirements of the design, construction method and quality standard of the steel structure fire retardant coating, and ensure the application effect, safety. The specifications is formulated in accordance with national engineering construction of the relevant policies and "giving priority to prevention, combining fire prevention and fire extinguishing. investigated characteristics of steel structure fire in China, summed up the experience of fire resistant coating for steel structure, and absorb domestic and foreign advanced technology and scientific achievement in fire retardant coatings for steel structures, and repeatedly solicited the relevant scientific research and design, production of construction, colleges and universities, public security department
Q:What are the materials of insulation firebricks?
The furnaces of firebricks are generally divided into two types, namely, unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, is a mix of powdery particles of many aggregates and one or multiple adhesives. They must be stirred well with one or multiple liquids when in use, which has a strong liquidity. Unshaped refractory materials generally refers to firebricks. They have standard rules about their shapes and can also be processed temporarily as needed.
Q:Which company needs the new refractories?
The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.
Q:How to use fireclay?
Fire-resistant adhesive material is needed, its effect equals to the cement. Cement will certainly do.
Q:Which refractory is better for building 1500 degree kiln ?
The top and wall use alumina hollow ball brick. If it is cubic kiln, the kiln bottom should use heavy corundum brick. If it is continuous kiln, burning zone should use alumina hollow ball brick, burning zone seal and kiln car face brick. If it is pit furnace, curved seal should use heavy corundum brick, and furnace wall and top should use alumina hollow ball brick. That depends on what kind of kiln it is. Curved seal and kiln car should use heavy corundum brick. You can add me friends to have further talks.
Q:What's the fire endurance of fire windows?
That is fire resistance rating, fire-resistant time in the case of fire! It can be basically classified into the following levels and the fire endurance of the fire window is as follows as well: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. This is in accordance with the latest specification of gb16809-2008 fire windows.
Q:Does anyone know what is the use of waste refractory materials?
Waste refractory materials can be 1, Recycled to do the aggregate and powder of castable , or make bricks. 2, can be reused after smash.3, Metal silicon is an anti oxidant in refractory material, mainly functioning as he oxidation resistance, at the same time improve its toughness.
Q:What is the principal part of silicious refractory material
Shenzhen Longgang Jiangyou Hua Boiler Accessories Co., Ltd. is specialized in refractory cement, refractory mortar, refractory clay, refractory aggregate and perlite. And other refractory | thermal insulation material, it has cooperated projects in Shenzhen, Huizhou, Dongguan, Guangzhou, Foshan, Zhuhai and other sites.
