$Flake Graphite With High Purity For Refractory$

Q:What are the characteristics of clay refractory materials?: Clay refractory has excellent performance in anti fatigue. The fatigue strength of the general metal is 50% ~ 40 of the tensile strength, and some composite materials can be as high as 70 ~ 80%. The fatigue fracture of the composite is from the matrix, which is gradually extended to the interface between the fiber and the matrix. Therefore, the composite material has omen before destruction, and it can be checked and remedied. Fiber composite material also has good performance in anti vibration fatigue. The fatigue life of The helicopter rotor made of composite material is longer that made of metal. I hope my answer will help you!

Q:What are grade classifications of the external walls fireproofing material?: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q:What are the physical properties of refractory material?: The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.

Q:What are the characteristics of the carbon composite refractories?: The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag

Q:How many types of special refractories are there?: Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials

Q:Where is refractory used? Thank you!: According to its refractoriness, it can be divided into ordinary refractory (1,580℃ to 1,770℃), high class refractory (1,770℃ to 2,000) and super refractory (above 2,000℃); according to chemical property, it can be divided into acid , neutral and alkali refractories, and including refractory used for special occasion. The current definition of refractory do not only depend on whether the refractoriness is above 1,580℃. At present, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, petrifaction, cement, ceramics, power, etc. Refractory generally has good thermal shock resistance, chemical attack resistance, low thermal conductivity and coefficient of expansion, widely used in chemical, construction material, mechanical manufacturing, and ceramics, accounting for 50% to 60% in the total output. It can resist high-temperature action. Refractory has many varieties. Refractory materials are widely used in metallurgy; chemical properties divided by acidic refractories. In addition, cement, silicates. Refractoriness refers to that when cones sample made from refractory has no load. Currently, refractory refers to that is widely used in metallurgy, including neutral refractory and basic refractory.

Q:How long is the duration of fire resistance of hollow glass magnesium board: It belongs to second level refractory building. The fire resistance limit of prestressed hollow slab is 0.7 hours, according to provision 3.2.7 and 5.1.5 of fire safety rules. When reaching 20 thick protective layer, the fire resistance limit of the prestressed hollow slab is 0.7 hours. When reaching 30 thick protective layer, the limit of the fire resistance of prestressed hollow plate is 0.85 hours. Protection layer of prestressed hollow board prefabrication is 15, plaster ceiling has 12 protection layers, the total protection layer amounts 27, which can achieve fire resistance limit of not less than 0.75 hour.

Q:Selection of refractory materials?: Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.

Q:What's the function of aluminium dihydrogen phosphate on the refractories?: Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
