Black Silicon Carbide is brittle and sharp and has electrical and heat conductivity in some degree. Aplications : Black Silicon Carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing. The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, Ceramic, etc. Black Silicon Carbide is also broadly used as high-grade refractory material and metallurgical additive.

Q: How is grade of fire endurance divided?: Level of the building is classified according to the importance, fireproofing, durable life and etc. different angles. Civil buildings are classified according to the following ways: 1, It is divided into five grads according to its importance: A, AAA level: Buildings with great memorial, of historic, international and national level. B, A level: High-grade residential buildings and public buildings. C, B level: Intermediate residential buildings and public buildings. D, C class: Ordinary residential buildings and public buildings. 2, It can be classified into four types according to the fireproof performance: Fire resistance level of the buildings is divided into four levels. Standard of fire resistance level is decided based on the combustion performance and fire endurance of the main components of the building. 3, It can be classified into four levels according to the durable life: A, A level durable life is more than 100 years. It is applicable for important buildings and high buildings. B, B level has a endurance for 50 to 100 years and it is applicable for ordinary buildings. A, C level has a durable life of 25 to 50 years. It is applicable for less important buildings. B, D level has a lasting year of below 15 years and it is applicable for temporary buildings.

Q: Do you know the refractories?: Alkaline material products: MgO, CaO based crystalline phase, because MgO and CaO are alkaline earth oxides, so it is called alkaline refractory. Their high melting point, alkali resistance slag (C/S > 2) corrosion ability is strong, belong to advanced refractory materials, but they are easy to hydration. Magnesia chrome brick, dolomite brick, brick olive and other products, the main chemical composition is MgO, CaO China also belongs to alkaline materials.

Q: Which are fireproofing external wall materials?: For example, Grade-A waterproofing external wall thermal insulation material: glass wool, foam glass, foam cement, hole-closed perlite, rock wool; Grade-B1 waterproofing external wall thermal insulation material: XPS after special treatment. There are also PU after special treatment, phenolic aldehyde and gelatine powder polyphenyl granule. Grade-B2 waterproofing external wall thermal insulation material: PE, and EPS. Grade-A: Completely fireproofing buliding material. Without probility of burning, completely fireproofing buliding material is expensive and unnecessary for home decoration. It is usually used in arsenal and electrical equipment department store. Grade-B1: nonflammable building material: With good flame resistance, nonflammable building material will not burn in the air or at high temperature, but it maby burn in the air and at high temperature. But when the fire source ransfers, it will be out immediately. Grade-B2: combustible building materials. Due to its small firresistance, it is easy to burn in the air or at high temperature, such as wooden building materials. The above are external wall fireproofing material of different classes.

Q: whether the fire resistant level of aerated concrete building blocks can reach the grade one?: Aerated concrete building blocks is made by calcareous materials (such as cement, lime) and siliceous material (such as sand, fly ash, slag), adding aluminum powder ingredients as filling agent, by mixing with water, casting molding, gas - expansion, raising the pre-cut, and then the high-pressure steam curing of silicate building blocks. when aerated concrete is at the temperatures below 600 ℃, the compressive strength will be increased slightly, when the temperature is at about 600 ℃, the compressive strength is close to the compressive strength at normal temperature, so the aerated concrete, as building materials, the fire performance can meet the national fireproffing safety standards level.

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: Why do magnesium oxide refractory bricks can be made into refractories?: The substance used in refractories must have the following characteristics and properties: 1, High stability: Anti-oxidation, anti-reduction and thermal decomposition; 2, High melting point of 2800 degree; 3, Low price. The magnesium oxide refractories have all these three characteristics and properties, particularlly in the aspects of melting point and stability .

Q: what's the varieties of thermal insulation material with A level fire?rating?: Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.

Q: what is the material of fixed first rate fire resistant window?: Window frames and fireproofing glass, fire sealing strip, fireproofing glass mound layer, which is infexible fan, and the flexible fans have to plus folding and closing window cleaner. (3) window frames must be integral with the building, using wood or iron to connect the wall. After the installation of the steel frame, the cement mortar must be watered between the window frame and the wall, and it should conserve more than 24 hours before normal use.
