Q:Who knows the refractoriness of high temperature lightweight firebricks?
Refractoriness refractory bricks with different melting points, the melting point is liquid and solid crystal phase at a temperature equilibrium. The vast majority of bricks are made of heterogeneous materials. No fixed melting point, it begins to appear to be melting and becomes complete liquid gradually, solid and liquid coexist over a wide temperature range, fusion and softening of refractory is messured by its performance at high temperature. Therefore, refractoriness is the temperature at which the multiphase reaches a certain degree of softening. Refractoriness is an important technical indicator in evaluating refractory bricks, but it can not be seen as the temperature ceiling. GB / T 7322 "Test Methods for high alumina brick refractoriness" alumina brick refractoriness test standards. refractoriness of some commonly used refractory bricks as follows: 1, clay brick 1610? 1750 ℃ ​​2,silicon brick 1690? 1730 ℃ 3, crystalline silica 1730? 1770 ℃ 4, hard paste1750? 1770 ℃ 5, high alumina brickx26gt; 1770? 2000 ℃ 6, magnesite refractory bricksx26gt; 2000 ℃ 7, dolomite refractoryx26gt; 2000 ℃
Q:Does the aluminum silicate thermal insulation material fireproof?
it can be fireproof and has a strong fireproof performance.
Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
What you said is the pixel! Only that has b1b2. Level b1 is the fireproofing level b1, because the particle does not belong to the fireproofing material. Only can fire retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name.
Q:Which schools are the best schools in the world for learning knowledge about refractories?
If you search on a worldwide scale, I might say you are ambitious!!! This major becomes an unpopular one and you must have to embark on graduate and PhD to specialize in it provided that you want to go abroad for further study. Wuhan University of Science and Technology may be the best school in this field with its close relatinship with many refractory manufacture factories across the country. Henan University of Science and Technology is also advisable in terms of this major, which probably promise you a job. Other universities in this regard are not quite familiar to me. You raised these questions, which shows that you are a layman to this major or not quite familiar with this major. If you have any questions, you can resort to me if I can.
Q:Can anyone tell me the requirements of the refractory masonry??
Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.
Q:Who can tell me about the foundry refractory materials?
The casting fireproof materials can be divided into three categories in accordance with chemical property, namely, acidic, neutral and alkaline refractories. The commonly used refractories are alkaline and neutral ones, such as alkalic magnesia-carbon bricks, fired magnesite bricks, magnesia-chrome bricks, magnesium-calcium bricks, and neutral high alumina bricks, corundum brick, clay bricks, etc. The shapeless ones include: castable refractory, ramming mass, gunning mix, coating, and dry vibration material, etc!
Q:How is grade of fire endurance divided?
Level of the building is classified according to the importance, fireproofing, durable life and etc. different angles. Civil buildings are classified according to the following ways: 1, It is divided into five grads according to its importance: A, AAA level: Buildings with great memorial, of historic, international and national level. B, A level: High-grade residential buildings and public buildings. C, B level: Intermediate residential buildings and public buildings. D, C class: Ordinary residential buildings and public buildings. 2, It can be classified into four types according to the fireproof performance: Fire resistance level of the buildings is divided into four levels. Standard of fire resistance level is decided based on the combustion performance and fire endurance of the main components of the building. 3, It can be classified into four levels according to the durable life: A, A level durable life is more than 100 years. It is applicable for important buildings and high buildings. B, B level has a endurance for 50 to 100 years and it is applicable for ordinary buildings. A, C level has a durable life of 25 to 50 years. It is applicable for less important buildings. B, D level has a lasting year of below 15 years and it is applicable for temporary buildings.
Q:What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
Insulation materials. Thermal insulation material is characterized by thermal insulation, which is one of the four traditional inorganic nonmetallic materials. Fire retardant material is cahracterized by heat-resistant. Refractory is a kind of materials of resisit high temperature. Fireproof material, which is different from thermal insulation material and refractory, is a synthetic material with some fireproof subtrate added. It is essentially resistant to high temperature.
Q:Which refractory is suitable for the tunnel kiln?
The refractories produced by the following ten manufacturers are relatively good. They are all being the top ten brands! 1. king coconut (Chinese well-known trademarks, famous brand, the nation's largest manufacturer of wood panels, large building materials chain enterprises, Hangzhou king coconut Holding Group Co., Ltd.) 2. Fuxiang (founded in 1998, the leading professional sheet production outstanding enterprises, Fuxiang Industrial Co., Ltd.) 3. Bunny (China famous brand, China Top brand, plywood industry iconic brand, large listed companies, high-tech enterprises, Edward Bunny decoration materials Co., Ltd. 4. new Millennium boat ( Chinese well-known trademarks, famous trademarks in Zhejiang, Zhejiang famous brand, well-known trademarks in Hangzhou, Zhejiang Province key forestry enterprises, the Millennium boat Group Hangzhou Huahai Wood Industry Co., Ltd.) 5. Jin Luli (China famous brand, Chinese brand-name products, Shandong Province, to wood-based panels and steel-based enterprises, hundred private enterprises in Shandong Province, Luli Group Co., Ltd.) 6. Albert (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL) 7. desert oasis (China famous brand lumber, China's top ten brands plate, sheet famous Chinese brand, oasis Wood) 8. Peng Che-hung (professional fire protection board development / production and marketing of the modern manufacturer, the introduction of advanced production technology industry HPL ) 9. Worldwide (professional magnesium fire plate glass production and sales of integrated large-scale well-known enterprises, famous brands Firewood industry) 10. Mogan (national key high-tech enterprises, China's largest and most influential environment-friendly decorative materials production one of the enterprises, Zhejiang Hua Yunfeng new material Co., Ltd.)
