Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
it has fire resistant level, incombustible material,and it should reach grade one level.
Q:How to choose thermal insulation materials for flood heating?
By controlling the foaming ratio, nucleating agent size, moudle pressure, temperature of screw, vacuum foaming technology, extruded sheet of different density can be made. The density of commonly used plastic extruded board is 25-50 kg per cubic meter. Plate density is the main factor affecting the cost of the extruded plate. The higher the plate density, the higher the cost price. Plate density is the main factor affecting the cost of the extruded plate. The lower the density of extruded board, the worse quality performance. Plate density of common plastic extruded is between 30 to 38 kilograms per cubic meter. The density of plastic extruded plate of exterior wall is between 30-35, if the density is too low, then the plate will not be strong enough, if high, flexibility of plastic extruded board will be inadequent, unable to bear the stress brought by housing settlement deformation, resulting in cracks in the wall. With the extrusion plate for floor heating should be in 36 kilograms per cubic meter. If it is too low, ground subsidence will occur due to the low strength, resulting in the ground crack. If density is too high, the thermal conductivity coefficient will increases, impacting energy saving. High density extruded plate is generally used for occasions having special requirements for compressive. Parking lot roof should use extruded plate above X350, whose density is 40 kg per cubic meter. The aircraft need to use the Ping extruded board above X500, density in 45 kilograms per cubic meters. High speed railway subgrade need to use extruded plastic board above 700KPA,
Q:What problems should be paid attention to while using refractory materials under a controlled atmosphere?
Pay attention to the performance of the materials, and the use of non oxide materials!
Q:Why can aluminium hydroxide not be used to make refractory material?
Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
Q:What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
Q:How to use fire-resistant soil?
It can live with water, not too sticky. Don't be too thin. It's best to put the stove in the inner wall.
Q:What's the classification of refractory material?
Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome
Q:Pals who know something about fire resistant material please tell me how many types of refractory material there are
Classified into ordinary and special refractories. The ordinary refractory material is calssified into acid, neutral and alkaline according to the chemical property. Special refractory material is calssified into high temperature oxide according to the composition for , infusible compound and high temperature composite in addition, can be divided into ordinary refractory products according to the fire intensity (1580 ~ 1770 DEG C), high-grade refractory products (1770 ~ 2000 DEG C) and special refractory products (2000 DEG C above). According to the products shape can be divided into bulk (standard brick, special-shaped brick block, special shape (crucible, sagger, pipe, etc), fibrous shape (silicates of aluminum and zirconium oxide and boron carbide matter) and irregular shape (fireclay, refractory castables and incompletely material).
Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
Go eastward 200 meters from the south gate of cultural square.
Q:How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?
The relative production is lower and material cost is higher, the lining of the refractory is thicker: 1, determine the weight of the refractory material according to the main structure of the bearing capacity, to prevent damage to equipment, fire-proof material damage after the surplus size and thickness of the thermal conductivity of refractory materials, the smaller the effective volume, production output, the cost of materials) to consider the selection of refractory material thickness. 3 from the point of usage (usage cycle, relative usage cycle is longer, because under the condition of invariable in the device's overall dimensions of the refractory lining thickness to determine several basic principles, according to the volume of the weight computation of refractories and refractory thickness, these items must be fully consider the pros and cons before decided. 2 according to maximum temperature that shell can withstand.
