Q:What are the materials of white firebricks?
They are made of baked refractory materials with pale yellow and a little brown on the surface and very cheap. They are mainly used to pile up smelting furnace and can withstand high temperature from 580 degrees Celsius to 770 degrees Celsius. While the firebricks, also called refractory bricks by others, have a certain size and shape. They can be classified according to manufacturing process, namely, the unburned bricks, burnt bricks and electrically fused bricks. Also they can be divided into common bricks, standard bricks and specific bricks according to different size and shape.
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:What are the construction fire-proof materials?
1. fire retardant coating 2. fireproof panel 3. fire proof and sealing material 4. flame resisting decorative materials 5. Green fire prevention materials
Q:Can anyone say something about what A-level fire-proof decorative material is?
Combustion performance rates of decoration materials ratess combustion performance of decoration materials A incombustible B1 flame retardancy B2 flammability B3 high flammability The B1 rate combustion performance of gypsum plaster board and mineral wool acoustic panel absorber installed on steel joist can be used as A-level decoration materials. Inorganic decorative coating applied on the A level substrate can be used as A level decoration materials. Hope you adopt
Q:What kind of refractory decorative board has good quality?
Baby Rabbit has excellent refractory decorative board. It once won the Chinese famous brand, and was awarded iconic brand in plywood industry and the most influential integrated service providers of indoor decoration materials . Fireproof panel is made from body paper(titanium coated paper, kraft paper) in high temperature and pressure through impregnation technology of melamine and phenolic resin. Refractory door slab is made by sticking fireproof panel on base materials such as density board or chipboard.
Q:Who knows about the fire endurance of sintered shaly hollow bricks?
Sintered shaly hollow bricks of Chu area have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance. The fire endurance of sintered shaly hollow bricks should not exceed1050 degrees otherwise they will burn excessively. I, actually, think that the temperature should be controlled within 980 degrees. I hope my answer may help you.
Q:what is the material of fixed first rate fire resistant window?
Window frames and fireproofing glass, fire sealing strip, fireproofing glass mound layer, which is infexible fan, and the flexible fans have to plus folding and closing window cleaner. (3) window frames must be integral with the building, using wood or iron to connect the wall. After the installation of the steel frame, the cement mortar must be watered between the window frame and the wall, and it should conserve more than 24 hours before normal use.
Q:Which fireproofing materials factory is the best in Xiangyang?
Xiangyang Shenglaide Door Technology Co., Ltd. Location: Taibai Road, Fancheng District, Xiangfan, Hubei Province Xiangyang Ai'ruite Door Technology Co., Ltd. Location: Scientific and Technical Pioneering Park, Xiangcheng District, Xiangfan, Hubei Province Xiangyang Innovation and Ideal Manufacturing Co., Ltd. Location: Xiangyang Xiangfan state Jianshe Road, Xiangzhou District, Xiangyang, Hubei Province
Q:Is aluminium oxide refractory material?
Yes. It has high melting and boiling point, stable chemical property. All refractory material almost contains aluminium oxide. Refractory materials have a large range and need specific requirements. Refractory material is divided into sizing refractory material, shapeless refractory material, ceramic fiber, refractory bricks and castable refractory. It can be subdivided according to temperature rating. Hope it is helpful to you.
Q:What does fire-resistant insulation coating have?
What is the most famous is that grade A is incombustible thermal insulation material. W W inorganic active wall insulation materials, cement foam insulation board, vitrified micro bead thermal insulation mortar, rock wool board, glass wool board, foam ceramics, etc.
