- Q: What is acid refractory material?
- Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick by using chromium oxide as the main component of the corrosion resistance of steel slag is good, but the poor heat shock resistance, high load low deformation temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, heat vibration performance, high strength, corrosion resistance to acid and salt, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry. 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. High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
- Q: How long is the fire resistant limit for ultra thin fire retardant coating?
- According to the "code for fire protection design of tall buildings", the fire resistance time of the component is at the first level: 3 hours, beam: 2 hours, floor: 1.5 hours;if fire resistance level is level 2, the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. For fire resistant coating, fire resistance time for ultra-thin fire retardant coating is less than 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be uesd.
- Q: how about the performance of aluminum silicate fire proof thermal insulation?
- aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing?agent, molding by high temperature and high press. MDF(medium density fibre board) structure is more even than natural wood. it avoids rot, moth-eaten and other problems, while medium density fiber board has small expansion and contraction, which is easy to be processed. Since the surface of medium density fibre board is smooth, the board is easy to paste a variety of finishings, which makes furniture more beautiful. A variety of decorative wood-based panel is to embellish their homes.
- 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: what is the original materials of fireproof coating?
- Fire retardant coating is composed of the base materials (that is film forming substance), pigments, ordinary coating additives, fire retardant agent and dispersion medium. In addition to fire retardant agent, other components functions the same as in ordinary coating, but its performance and thickness are specifically required. Some solvent-based fire retardant coating can burn upon encountering fire before construction.In fact,It is the flammable solvent contained in the coating that is burning while substances such as the base materials and fire retardant agent does not burn. Because solvent-based fireproof coating contains organic solvent and these fire-resistant coating, once leaked from the bucket, are likely to cause a fire. Fireproof coating on the substrate can insulate heat only after the solvent contained evaporates compeletly.
- Q: What material is refractory material?
- alumina refractory concrete, silica brick clay brick, metal ceramic, high temperature machine coating fiber reinforced ceramics, diatomite product, asbestos products, insulation board refractory. The definition of refractory can be searched in the website.
- Q: Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?
- When casting ingot, after high temperature molten steel is poured into ingot mold, molten steel keeps shrinking during cooling, for example, killed steel is shrinking 3% --5%. because of fast heat dissipation of ingot head , some shrinkage holes appear at the head of ingot. Therefore, you should cut shrinkage holes which account for more than 15% of the ingot quality in the head while cutting steel ingot cogging. If effective measures were taken to insulate the head of ingot from heat, then the coagulation time of ingot head would lag behind in the body of the ingot solidification, which will greatly shrinkage holes, improve ingot yield so as to reduce energy consumption of steelmaking. Adiabatic plate can achieve this purpose. China Heng insulation board has the advantages of uplifting adiabaticity and small heat capacity, so that it greatly reduced heat loss of molten steel, And the tundish can be directly put into use without preheating, thereby saving a large amount of preheating fuel. So in the current process of continuous casting, the heat insulation board is the main material of tundish lining.
- Q: What is the new fireproofing standard of external wall thermal insulation materials?
- 1, The height of fire barrier zone is not less than 300, and the thickness is same to the external insulation system; 2, the horizontal dividing joint should be set on the boundary between fire barrier zone and thermal insulation system; 3, Fire barrier zone is usually set in the horizontal direction, the fire barrier zone should be set above the door and window openings, the distance between the low edge of barrier zone and upward side of the hole should not exceed 500mm; 4, The construction of fire barrier zone insulating layer should carried on from bottom to top with EIFS insulating layer, which is not first leave the place in the EIFS insulating layer, and then paste fire barrier zone insulation board; 5, pasting the insulation board fire barrier zone insulation board and EIFS insulation board should be stitched closely, the width is more than 2mm gap application EIFS insulation materials or fire-retardant foam polyurethane padding;
- Q: Classification of porosities in refractories and their effects on properties
- Effect of apparent porosity on properties:The porosity is high, the volume density is low, the structure become more loose, generally low strength, corrosion resistance worse (slag infiltration and erosion along the hole toward the inside), but to improve the thermal shock resistance (resistance to thermal shock and not damaged).
