Q:I wanna ask what are the acidic refractories?
Usually, acidic refractory refers to a kind of refractory which contains a amount of silicon dioxide. There are the following: (1) silica brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. The main features of the acidic refractories is resistant to the erosion of acidic substances (acidic residue) in high temperature, but is easy to react with alkaline material (basic slag). zirconite fireproofing material and silicon carbide as the special acidic refractories refractories are also in this category.
Q:Who knows about roof fireproofing materials?
Roof water proofing materials: synthetic polymer waterproof rolls, high polymer modified asphalt waterproof coiled material, sheet metal, synthetic polymer waterproof coating, one-component water curing polyurethane waterproof coating, penetration crystalline waterproof coating. Secondly, we have to choose materials that are suitable for roof water proofing. The right waterproof materials have better waterproof performance, TS-3B one-component water curing polyurethane waterproof coating is very suitable and the performance is good. Since traditional roof waterproofing materials have requirements on the moisture content of the formation level which should be less than 9%. It is really important to choose which materials to repair leaking roofs. Kitchens and toilets are moisture, the formation levels of buildings are hard to satisfy requirements, thus, waterproof layer and formation level are easily get separated and are ineffective in waterproofing.
Q:What are the applications of refractory?
Refractory materials are widely used in iron and steel smelting , glass, cement kilns, non-ferrous metal metallurgy, environmental protection, and chemical, etc. For example: For a car of 1.5 tons, do you you know how much refractory it use? The answer is: To produce top hat or other steel products, glass for vehicle windows, nonferrous metals kile aluminum and copper, plastic products of the body all needs refractory. A car of 1.5 tons needs to consume a total of 10Kg refractories.
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's the feature of construction external wall fireproof and thermal inuslation matertial?
Building external wall fireproof thermal insulation material is made by stirring, casting, foam protecting and cutting with industrial by-product gypsum as the main raw material, adding sulphate aluminium cement, fly-ash, polymer additives and other materials. It has excellent properties of respiratory function , air permeability, water impermeability, recycling system data, wind load resistance, shock resistance, thermal insulation, fireproof and sound insulation.
Q:What is the the best matching ratio of refractory cement?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will produce a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees. Refractory cement can be used together with ordinary sand, and the ratio of cement and the sand is about 30 percent.
Q:How to divide the fire resistant level of EVB?
According to the indicators of amount of smoke, heat value, burning rate, and ignition point, combustion performance insulation materials are divided into A (non-combustible), B1 (flame retardant), B2 (flammable), B3 (combustible). It can be divided into the organic and inorganic types: The organic includes polyurethane and polystyrene board, the inorganic the includes glass wool and rock wool. The price of organic is lower, and it is combustible materials, it will produce hydrogen cyanide and other toxic gases when burned, the inhaled would die. The inorganic material is completely non-combustible insulation material.
Q:What are the refractory materials above 1000℃
corundum would be fine
Q:What is the limit of fireproof rolling shutter?
Fireproof rolling shutter door is a kind of fire protection and heat insulation facility which is suitable for the large openings of buildings, having a certain effect on the design and installation. Fire shutter doors are widely used in fire partition of industrial and civil building. It can effectively prevent the spread of fire, to protect the safety of life and property. It is an indispensable modern building fire facilities. According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
Q:How many types do refractory bricks have? Where the quality of refractory material is best? What is the model?
Sinosteel Luoyang (Luoyang Refractory Material Plant in the past): High alumina(mainly blast furnace), Gongyi. There are also a series of high-tech materials (silicon carbide, carborundum, etc.) a major producer of high alumina; silicious: Resistant material for steel, glass furnace, cement kiln); magnesia. Divide from uses and divide from chemical texture; silicious(glass furnace): Xinmi, Hennan Province, Lengshui River, coke oven, etc.). As for the models, Yixing and Changxing in Jiangsu Province: Haicheng, Liaoning Province; silicious, I do not understand your intentions; magnesia (nonferrous, steel refining; magnesia: High alumina brick; Dashiqiao area! Please put it in detail.
