Q:How many hours of the fire endurance time of the rock wool laminboard?
The fire endurance time of the rock wool laminboard is generally adout 1 or 2 hours.
Q:who knows the uses of refratories?
Of course, the role of the refractory material is fireproof, generally used in large buildings. It can reduce casualties and economic losses caused by the fire. it also can be used on the chemical instruments. ! !
Q:How can refractory material of the electric furnace be used for longer.
Do not exceed the temperature, do not exceed the limits of use in order to achieve the best performance and the longest service life
Q:What's meaning of CN of fire-resistant material?
The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.
Q:What kind of materials are needed to make refractory bricks?
Fubang Decoration of Anhui province help you with the question: According to requirements, there are different materials, acid refractory material, such as silica bricks; neutral refractory material, such as high alumina brick; and basic refractory material such as magnesia brick.
Q:What are the new refractories?
Most are ordinary refractories.
Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?
Residential buildings should meet the following requirements: 1, The height of building is greater than or equal to 100m, the combustion performance of thermal insulation material should be level A. 2, The height of building is greater than or equal to 60m but less than 100m, the combustion performance of thermal insulation material should not be less than the level B2. When using the level B2 thermal insulation material, each layer should set a horizontal fire barrier zone. 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 thermal insulation material, each two-layer should set a horizontal fire barrier zone. 4, The height of building is less than 24m, the combustion performance of thermal insulation material should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone. According to this understanding, it can not be set.
Q:What kind of refractories do the anode baking furnace use?
5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
Q:What are the characteristics of clay refractory materials?
Refractory clay refers to the refractory clay and bauxite, whose refractoriness is over 1580℃, which can be used as refractory materials. Apart from high refractoriness, they can maintain stability of volume under high temperature conditions and has resistance to slag, the sudden cold and hot, and mechanical strength, so after calcination, it can be abnormal firm.
Q:What's the refractoriness and how to measure the refractoriness?
Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
