Grinding Black Silicon Carbide

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. It is used for making bonded and coated abrasive tools, grinding metal and non-metal materials of lower tensile strength, such as gray cast iron yellow bronze,aluminum, stone, leather, rubber, etc.

Green and Black Silicon Carbide with High Purity SiC

Q: The fire prevention board line is made of what material?: (1) if it's real wood floor, the line should be made of wood. The ready-made wooden line, walnuts, price range depends on the texture width. The common width is 100 mm. One linear meter is around $17 - $30. Paulownia is cheaper with one linear meter more than 10 yuan. When it is composite wood floor, high-density plate modelling line can be used. The price is commonly between 40 to 80 yuan (2400 x 1200 mm), which depends on the thickness and density and also the factory. There are also imitated wooden aluminium line. (3) if it's the marble ground, you would better use marble line, which is 200 yuan one square meter. It's price is also unequal. The imitated stone is also available. There are a lot of kicking decoration materials and it depends on how you use it. That is to say crural line should be coordinate with the ground. It means that it sjould not only to be beautiful but also to be practical. It would be better if it is relatively cheap as well.

Q: How long is the fire resistant limit for ultra thin fire retardant coating?: According to the "code for fire protection design of tall buildings", the fire resistance time of the component is at the first level: 3 hours, beam: 2 hours, floor: 1.5 hours;if fire resistance level is level 2, the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. For fire resistant coating, fire resistance time for ultra-thin fire retardant coating is less than 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be uesd.

Q: How to count the construction costs of refractories?: In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.

Q: What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?: A less accurate view of the statement is probably the meaning of the “construction of refractory material" , for example, pouring castable can be called “knot”, the pounding of the construction can also be said that, so it is with spraying paint.

Q: Where is the sizing nozzle for refractories? Just enter the line, master into!: Hua Heng refractories in the industry reputation is good, especially in the Southern small steel sales are among the best!

Q: can slag tailings be used to be the base materials of refractory materials ?: the rest of it can be used as refractory additives. the scale currently used clay bricks to make high-temperature liquid. It is easy to produce large amounts of liquid because of the high iron content, instead of its refractoriness. But it can be used as refractory minaralizer.

Q: What's the fire resistance rating of the exterior fire?retardant?coating?: Current fireproofing material is mainly classified into five grades: A class: Incombustible building material which is almost incombustible. A1 class: It is noncombustible and cann't cause open fire. A2 class: It is noncombustible but needs to measure the smoke it will cause and that should be qualified. B1 class: Flame-retardant building materials: Good in fire retardation, it is non-combustible when meeting open fire in the air or under high temperature, and it is difficult for the fire to spread quickly. Besides, when the fire source is removed, combustion stops immediately. B2 class: Combustible building material: It has certain fire retardation. In the case of open fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as the spread to wooden pillars, timber roof truss, timber beams, wood stairs, etc. B3 class: Flammable building material has no fire retardation effect at all. It is highly combustible with big fire risk. Besides, the classifications of fire resistance rating of building materials are different according to different standards: dDIN4102: A1, A2, B1, B2, B3; x0dEN13501-1: A1, A2, B, C, D, E, F. Hope it helps.

Q: What's the fire resistance test method of doors and roller shutters?: Fire resistance test method of doors and roller shutters: This standard specifies the fire resistance test method for roller shutter doors under standard fire conditions. The method is used to test the fire resistance of the ventilating duct when bearing the external fire (A duct) and internal fire (B duct). Fire resistance test of vertical ducts may be conducted referring to this standard. 1.Test specimen1.1 The test specimen is obtained by cutting from any part of the qualified metal tube unless otherwise relevant standard or mutual agreement specifies the cutting position of the metal tube. 1.2 Length of the specimen: L≈2.5D+50mm (D: outer diameter of the metal tube). The cut surface of the specimen must be perpendicular to the axis of the metal , and the seamed edge of the cut should be round off. Test method GB243-82 of metal tube necking 2. Test procedures 2.1 In the test, punch or press the metal tube into the tapered conical seat (see Figure) with a hammer or press machine, and make it uniformly diminished to the regulated shrinkage X which is calculated according to the following formula: Test method GB243-822 for metallic pipe necking: The inner wall of the seat cover used in the test should be polished, and has certain hardness and is coated with lubricating oil. Its conicity is 1:10, 1:5 or others in accordance with relevant standard provisions. If there is no provision, then adopt the conicity of 1:10. This standard is not suitable for: a) The pipeline whose fire resistance depends on the fire resistance of the ceiling; b) The pipeline with access door, unless otherwise the access door is included into the pipeline and tested together; c) The pipeline with two or three sides; d) Fume exhaust pipes;

Q: What is the quote of fireproof and soundproof materials used in KTV?: 1. fire retardant, sound absorbing sheet,eggs,pyramid,sound-absorbing material, piano room, studio, KTV, with glue on the rear, 15 Yuan 2. bar, KTV, fireproof sound insulation cotton, sound-absorbing materials, studio, eggs, drum practice room, sound-absorbing and sound insulation materials, pyramid, 25 Yuan 3. fireproof wood excelsior absorbent, sound absorbing board, wall ceiling decoration materials, materials, theater, KTV, wood color fiberboard, 30 Yuan.

Q: What are the requirements for fire?rating of construction suspended ceiling material ?: In fireproof design of all parts in interior decoration, fireproof design of suspended ceiling is the most important. Because the flame is burning up in fire and the suspended ceiling is the first and most direct part to test fire; at the same time, it has a direct impact on the evacuation. Therefore, in indoor suspended ceiling decoration design, fireproof work should be considered fully. Code of fire prevention design of interior decoratio of buildings has detailed provisions for fireproof?performance of indoor suspended ceiling materiial of different civil buildings. Suspended ceiling (sprung roof) refers to the top decoration of a house. Suspended ceiling, an important sub-project in construction decoration project, and the hidden layer of electrical equipment, ventilation and air condition, communication and fireproof, alarm pipelines, etc. has the functions of thermal insulation, sound insulation and absorption. Suspended ceiling plays an important role on the entire house decoration. Proper decoration to the house top surface, can not only beautify indoor environment, but also create a colorful interior artistic image. When choosing decoration materials and design of suspended ceiling, you should follow the principle of saving material, being solid, safe, beautiful and practical.
