Product Description
Aluminate cement is a hydraulic cementitious material prepared by calcining aluminum clinker and limestone as raw materials, with calcium aluminate as main component and alumina content of about 50%.
Aluminate cements are often yellow or brown color, and even gray color The main minerals of aluminate cement are calcium monocalcium phosphate (CaO·Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO·SiO2). The colors are mostly gray and white.

- Q: What is the upper temperature limit for refractory materials?
- Different materials are different. In the professional field, there is a triangulation cone softening point experiment as a reference for using the upper temperature limit.
- Q: Kinds of refractory mortar
- It needs no heating when hardened. There are two kinds of refractory mortar, the finished products and semi-finished products. Clinker is compounded in proportion according to the hardening temperature. (3) Chemical bonding refractory mortar is made from refractory aggregate and chemical binders (inorganic, high alumina refractory mortar). After this refractory mortar with thermal hardness is hardened, it has some contraction. Ther is a wide variety of refractories used on the constrcuction sites: // a, Advanced refractories (1770 ~ 2000 ℃) and AAA level refractories (2000 ℃ above). It can only be delivered in dry state. Air hardening refractory mortar is often compounded air hardening binders such as sodium silicate. It will harden below ceramic bonding temperature. According to different binding agents.
- Q: How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?
- Fire?rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grades. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire?rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q: Is there requirement for radiation indicator in refractory?
- All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
- Q: What are the construction measures of refractory material in winter? Please descriptive briefly.
- Binding agent should be attaced great importance to when construction is conducted in winter. Generally if the bingding agent is water or cement, antifreezing measures should be taken.
- Q: How to determine the fire resistance rating of the aluminium-plastic?panel?
- Class A incombustible and thermal insulation material: inorganic active wall thermal insulation material, cement foam insulation board, glass bead thermal mortar, rock wool board, glass wool board, foam ceramics, etc. With many characteristics of low density, low thermal conductivity, high pressure bearing capacity, convenience of construction, economy and durability, A class incombustible material is widely used as thermal insulation material for heat pipelines, thermal equipment, other industrial pipe-line equipment and industrial buildings, and thermal insualtion and sound absorption material for the building envelop of industrial and civil buildings. Because of good thermal stability, it is more often used as fire-proof and protective coating material of the steel structure.
- Q: What are fireproofing materials?
- Class A incombustible material: Granites, marbles, terrazzos, cement products, concrete products, plasterboards, clay products, glass, tiles, mosaics, steel, aluminum, copper alloys; B1 class flame nonflammable materials: Ceiling materials: gypsum plaster boards, fibrous plasters, cement particle boards, mineral wool decorative acoustic panels, glass wool decorative acoustic boards, perlite decorative acoustic boards, flame retardant plywoods and medium density fiberboards, rock wool decorative panels, flame retardant woods, aluminum foil composite materials, flame retardant phenolic laminates, aluminum foil glass fiber reinforced plastic composite materials; Wall covering: gypsum plaster boards, fibrous plasters, cement particle boards, mineral wool boards, glass wool boards, perlite boards, flame retardant plywoods, flame retardant medium density fiberboards, fireproof plastic decorative plates, nonflammable double-sided particle boards, multicolor paints, nonflammable wallpaper and textile wall cloth, flame retardant simulated granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plates, PVC plastic clapboards, high-strength and lightweight composite wallboards, fire-retardant molded wood composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.
- Q: What are the types of advanced refractory?
- According to the chemical composition of minerals,refractory can be divided into eight categories: 1, siliceous material. 2, aluminosilicate materials. 3, magnesia materials. 4, dolomite materials. 5, chromium materials. 6, the carbonaceous material. 7, zirconium materials. 8, special refractories. 1. refractories according to chemical properties can be divided into three categories: 1, acidic refractory materials. 2, neutral refractories. 3, basic refractories. 1. refractories according to chemical properties can be divided into three categories: 1, ordinary refractories, refractoriness is 1580-1770 degrees. 2, advanced refractories refractoriness is 1770-2000 degrees. 3, super refractories refractoriness higher than 2000 degrees. 3. refractory according to the forming process can be classified into seven categories: 1, natural rock molding process. 2, compression moulding refractories. 3, moulding refractories by casting. 4, plastic molding refractories. 5, ramming molding refractories. 6, injection molding refractories. 7, extrusion molding refractories.
- 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: What are the types of steel refractory materials
- Large steel ladle usually made with magnesia carbon brick, of course, it contains a intermediate layer (such as good a little high alumina castable), heat insulation layer and heat preservative materials Alumina-magnesia castable is OK for small steel ladle
