Magnesia is divided into sintered magnesia, light burned magnesia, fused magnesia three categories.Magnesia refractory material is one of the most important raw materials, aluminum used in the manufacture of all kinds of magnesite brick, magnesite brick, ramming material, repairing, etc.Contain a more impurities, are used to construct steel furnace bottom, etc.Sand in the main ingredients for magnesium oxide, impurities such as CaO, SiO2, Fe2O3, magnesium oxide as basic oxide, melting point is 2800 degrees, after the high temperature heating into stable cubic crystal, commonly known as periclase.By magnesium hydroxide by high temperature calcination, hydration resistance ability.Sintered magnesia is mainly composed of magnesite, magnesite or water from the water extract of magnesium hydroxide by high temperature calcination.Hydration resistance ability.Magnesite calcination under 700-950 ℃ is escaping CO2, magnesite as soft porous loose material, cannot be used for refractory material;Magnesite through 1550-1600 ℃ calcination so-called burned magnesia said sintered magnesite.Light burning magnesium powder is bending, compression, high strength, hard, gelled material, widely used in national defense, medicine, chemical industry, paper making, shipbuilding and other industries.In the building materials industry produce tire sub board, particle board, heat preservation columns, railing, artificial marble, asbestos tile, ordinary tiles, wall panel, laying on the ground.With the progress of science and technology, light burning magnesium powder application more widely, civil products, light and heavy machinery packing boxes, packaging can do sill, high-temperature refractory material, also can make beautiful luster strong furniture, in the machinery industry to do model.

Q:What is the fire endurance of ceramsite concrete blocks?: What is mentioned in fire?safety?rules is that the fire endurance of 240mm thick hollow brick of ceramsite concrete is 2.9h, so 190mm thick hollow brick is 3h. B05 thickness(mm), fire endurance(h). Combustion performance 100 4.0. Non-combustible component 150 6.0200 8.0300 〉8.0B06 100 〉4.0150 〉6.0200 〉8.0300〉8.0: The fire endurance performance of building blocks wall in the table is taken from the Tianjin Construction Standard "light steam pressing aerated?concrete?block" DB / T29-128.

Q:Fefractory of aluminium oxide.: It can be refined into castable refractory and refractory bricks, according to temperature rating. There are shaped refractory material and shapeless refractory material, and ceramic fiber. So it must be specific. There is a large range of refractory, which basically contains the aluminium oxide.

Q:how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q:What are the best refractory materials in 2,400 Celsius degree?: and carbon fiber or nanomaterials.

Q:How to divide the fire resistant level of construction thermal insulation materials?: How to divide the fire resistant level of construction thermal insulation materials: Combining three versions of GB8624 (1997,2006,2011) external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division, very professional and technical, so it is hard to say clear now. For details, please contact Qingdao Shanfang Instrument Company who is specialized in fire?rating tester for external wall thermal insulation materials.

Q:What are unshaped fire-resisitance materials?: Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods

Q:How to divide the materials according to the National Fireproofing Material Standard?: Each country has its own fire safety standards, I do not know which country's standard do you want to know, and each country of fireproof material to the division level is not the same. GB GB 8624, the German standard DIN 4102-1, the British standard BS 476, French standard NF P92 -501 and so on. GB 8624 is Chinese building materials and grade of combustion performance. The information coming form fire resources network (FireTC.

Q:What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?: Hello there. Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.

Q:How many kinds of fireproof materials are there in the market?: Inorganic insulation materials basically can achieve the goal, such as glass wool, rock wool, and foam glass. The phenolic foam in the organic foam materials is special. Phenolic foam is not only good at insulation, but also good at compounding with steel and other materials to achieve A-level performance, and the A-level insulation materials are: rock(ore) wool, foam glass and inorganic thermal insulation mortar. Insulation materials with B1 combustibility mainly are: Phenolics, polystyrene granules, etc. The insulation materials of fire barrier zone can use such A-level materials as rock (ore) wool, foam glass, and inorganic thermal insulation mortar, etc.
