Q:Who can introduce the external wall thermal insulation materials fire rating regulations?
External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set horizontal fire barrier zone 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone.
Q:What is the difference between the fire rating and the fire resistant level of the fire-fighting equipment?
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. Fire resistance rating of the building is divided into four levels. Standard of fire resistance rating is determined by the combustion performance and fire resistance of the main housing member. Level one or two are in accordance with the Article 1.0.2 in this specification.
Q:Is the ball mill used in production of refractories?
Refractory is a kind of non-metallic material that is of resistance to thermal shock and chemical erosion, low thermal conductivity and low expansion coefficient. The refractoriness of the refractory is not less than 1580℃. The usage of the refractory is broad. Refractory materials include refractory bricks and powders. Abandoned refractory bricks can be recreated as new bricks after they are crushed by a crusher and grinded by a ball mill. The ball mill and crusher are needed to grind and crush the material in the production of the refractory. The ball mill produced by Zhengzhou Xinhai Machinery Manufacturing Co. has excellent performance and there are many successful cases in Inner Mongolia, Heilongjiang and Guangdong. At the request of the national environmental policy, the company adjusts the equipment details, allowing the equipment to ensure the volume of production while reduce energy consumption.
Q:What substitutes are available for high-end refractories in addition to zircon sand?
Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..
Q:which kind of refractory is commonly used in the industry
Therefore it is known as special fire-resistant materials, such as yttria, high alumina raw material (sometimes neutral), olivine,which is used for alkalinity furnace, dolomite, and we roughly divided into several categories, beryllia, cerium oxide, these materials have a strong alkaline slag resistance, thorium oxide, lime, serpentine, which is picked from these refractory raw materials. the raw materials of basic refractory materials are mainly magnesia clay and titanium oxide, but because not many sources of raw materials, it can not be widely applied in the refractory industry, and we can analyze which kind of materal is processed by the pulverizer. There are many kinds of refractory materials, rotary kiln can only be used in particular circumstances. These materials have a variety of slag resistance at different degrees. the main material of special refractories is zirconium oxide. the refractory clay is the most basic and most widely used raw material in the refractory industry.
Q:Which are fire proofing thermal insulation materials?
Grade-A fire proofing inorganic thermal insulation materials include rock wool, glass wool, vitrified micro bead, foaming cement, foaming ceramics, vacuum thermal insulation board,
Q:Which kind of refractory does insulation board belong to ?
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent
Q:Does anyone know about the fire resistance period of thin fireproof coatings?
Outdoor thin steelwork fireproof coatings have a fire resistance of 2.0 hours, the thickness of coatings is between 4.5 to 5 mm, the standard amount is 5.5 to 6kg per square meter. Specific situations vary according to the thickness data provided by manufacturers . The fireproof coatings are applicable for the surface of combustible substrates, which can reduce the flammability of the surface being painted, and block the rapid spread of fire. They can be used to improve the fire resistance of the materials being painted. The fireproof coatings are coated on the substrate surfaces. They are also rustproof, waterproof, wearproof, heatproof and anticorrosive apart from flame retardant. They have good tenacity, stainability, adhesiveness, glossiness and fast-drying nature.
Q:How long is the fire-resistant time of fireproof wooden door?
Wooden thermal insulation fireproof door using flame-retardant timber or flame-retardant timber products to make door frames, skeletons of door leaf, door panels. If the door leaf need to be filled with materials, the filling materials should be fireproof thermal insulation materials which is non-toxic and harmless to human body, and matched fireproof door composed of fireproof hardware. Use doors without age limits.
