- Q: The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
- Yes. After moulding by casting in the firing of 1450 ° degrees.
- Q: Does the production of refractory belong to advanced technology？
- Refractory is traditional ceramic material. We can only say that national development is relatively backward. If the refractory is counted as new material, then it still has huge development potential.
- Q: What is the fire endurance of ceramsite concrete blocks?
- The fire endurance of 240mm thick ceramsite concrete blocks is 2.9 hours. It is made by adding pottery into fine aggregate, using cement as binding material, by mechanical mixing, molding machinery and natural protection. Ceramsite building blocks are used as wall material, which can reduce workers' labour intensity. It saves work and material. There is no empty drum during rendering. It is not easy to produce fissure. It has sound insulation, good thermal insulation performance, and is convenient to decorate. Nails, expaned setscrew and no wood anvil can be directly hit into wall. Moreover, It has high firmness.
- 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: How is refractory material made?
- It is made from polyester.
- Q: Which one is better, fire-resistant wood or steel?
- Rebar would weaken and quickly collapse in the fire, and the fire resistance of a heavy log is much better than steel. In many ways, the fire resistance of a large log is equal to reinforced concrete. The heat transfer capacity of wood is 400 times smaller than steel, 8.5 times smaller than concrete. When burning, wood will form a layer of carbon in the surface, and as long as the cross-section of the timber is over a certain size, this layer of carbon it will become an excellent flame retardant layer to protect the interior of the wood from burning. So the United States and Japan and other European countries allow and encourage the use of wood structure with a large section (beam column of 8 inches or more) to construct public buildings without the need for fire treatment applied to wood surface. I hope my answer will be helpful to you.
- Q: What do refractory materials include?
- What refractories are included? Refractories include AZS brick, corundum brick, direct-bonded?magnesia-chrome, carborundum brick, silicon nitride bonded silicon carbide brick, non-oxide refractory materials such as nitride, silicides, sulfides, borides and carbides, oxidation calcium, chromium oxide, aluminum oxide, magnesium oxide and beryllium oxide.
- Q: Who knows the external wall thermal insulation materials fire rating requirements?
- The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
- Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
- The thickness of steel structure fire retardant coating hasn't been regulated in the steel structure application specification (CECS24:90). The above thickness refers to a certain thickness that must (at least) achieve a certain time of the fire resistance. The thickness of fire-retardant coating in engineering is generally determined according to factory inspection report. We use thin steel structure fire retardant coating: 2.5 hours' fire resistance with the thickness of 4.9 mm; 2.0 hours' fire resistance with the thickness of 3.5 mm; 1.5 hours' fire resistance with the thickness of 1.75 mm; 1.0 hours' fire resistance with thickness of 1.17 mm. I hope I can help you.
- Q: What refractory materials are used in power plant
- And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
