Product Description

Alumina bricks are made from bauxite of super quality, bonding chamotte and additives. The main Al203 content is 48%-99%. The advantages of high alumina bricks are high refractoriness, anti alkaline/acid erosions, good strength under high temperature and good thermal shock resistance. High alumina bricks were widely accepted in thermal equipment of metallurgy, petroleum, chemical industry, construction materials, machinery and militaries etc.

Q: What is fireproof concrete?: Silicate fireproof heat-resistant concrete using temperature can reach 700 DEG ~800 DEG, the main mechanism of its heat is dehydrated calcium hydroxide silicate hydrates series of cement clinker under high temperature, the calcium oxide and slag and mixing activated silica material in the three and two aluminum oxide and the reaction of anhydrous calcium silicate and anhydrous aluminum acid calcium has strong heat resistance, the fire resistance of concrete is a certain. Such as the use of high alumina bauxite and broken bricks, magnesia brick and magnesia for fireproof heat-resistant concrete materials with the highest using temperature can reach 1100 DEG C.

Q: What's the difference between high alumina refractory bricks and high alumina refractory bricks?: The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.

Q: What is the standard size of high alumina brick?: The country has laid down a number of criteria for the use of refractory bricks to unify market demand.

Q: The difference between aluminium refractory and magnesia refractory: Aluminum refractory belongs to neutral refractory material, usually refers to silicon aluminum refractory materials, such as: high alumina brick, clay brick, high alumina castable and other products, the production of raw materials is mainly bauxite.

Q: What are the common thermal insulation materials for thermal conductivity?: Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.

Q: What are the alloy wear resistance materials?: Alloy wear-resistant materials from different manufacturers different components in Beijing Naimo company as an example, the following alloy wear resistant material:1: Ni Cr alloy wear-resistant material2: chrome carbide wear-resistant material3: high manganese alloy wear-resistant material4: tungsten carbide alloy wear-resistant material5: nickel tungsten alloy wear-resistant material

Q: What are the high temperature refractory mortars made of?: Siliceous mud, mineral composition and chemical composition is similar with silica, excellent corrosion resistance, water glass slurry, drying shrinkage, but also can be used for bonding fiber products, sealing furnace wall.

Q: What is spalling resistant high alumina brick?: Spalling resistant high alumina brick is a kind of high alumina brick. Antistripping high alumina brick with high grade bauxite and containing Zr02 synthesis as raw material, according to a certain proportion by high pressure molding system in sintering products, products with anti stripping ability, and have the anti erosion potassium, sodium, sulfur, chlorine and alkali salt, low thermal conductivity and other properties that is the transition zone of cement kiln and decomposition of ideal material with remarkable characteristics, the product is good thermal shock resistance, strong ability to adapt to the environment. It is used in the preheating or decomposing furnace, grate cooler and so on.

Q: Is glass wool inorganic thermal insulation material?: The use of glass wool, glass wool is usually used as raw materials of various types of insulation materials, such as glass wool board, glass wool, glass wool, glass wool pipe, can be used in the following areas:1) roof insulation, cold protection, sound-absorbing materials; 2) building exterior wall insulation and cold protection; 3) entertainment places, theaters, television stations, radio stations, laboratories, sound absorption treatment.

Q: What is the high temperature limit of refractory bricks and refractory soil?: Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
