High Aluminium Ceramic Fiber Board

Q: Which company needs the new refractories?: The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.

Q: What is the importance of silicon powder in refractory processing?: in amorphousness it is mainly the mobility

Q: How long does it take for refractory cement to solidify?: 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.

Q: Who knows the classifications of magnesia refractory?: Magnesia chrome series products: The main ingredients of magnesium chromium series are MgO and Cr2O3. Periclase is the first phase and magnesia-chrome spinel is the second phase. Products belonging to this series are magnesium chrome brick and chrome magnesia brick. The main ingredients of magnesium aluminum series are MgO and Al203. As they generate MgO and Al203, all magnesium chromium series products contain magnesia material. magnesium calcium series products The main components are MgO and CaO. They have high melting points, which are important magnesia materials. 5, magnesium silicon series products: The main component of magnesite series is SiO2, when the C / S<5, SiO2 and MgO generate MgO.Al2O3 (forsterite). From the perspective of microscopic mineral, main products of pure aluminum series include magnesium aluminum brick, periclase spinel brick, corundum spinel brick and aluminum-spinel castable in unshaped materials. I hope this answer can help you.

Q: The difference between refractory and thermal insulation material: Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.

Q: how to divided the external wall thermal insulation materials fire rating: The external wall thermal insulation materials is divided by fire rating: 1. The thermal insulation material of level A combustion performance: inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and 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 differences between first-level fire-resistant materials and second-level fire-resistant materials?: Level B1: building materials with flame retardancy: this kinds of materials have good effect in flame retardation. Under the case of open fire or high temperature, it is not easy to be ignited and spread quickly, and when the fire source is removed, fire would stop immediately. Level B2: combustible building materials: combustible building materials also have effect in flame retardation. It will get burnt as soon as it meets open fire or high temperature, so it can easily give rise to rampant fire, such as wooden pillars, wood roof trusses and wooden stairs.

Q: What are the specifications of fireclay bricks?: Dimensions of refractory bricks : 230 * 115 * 65mm

Q: What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?: 04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
