Black Silicon Carbide 1-10mm 90%

It is produced in a high temperature electric resistance-type furnace from a mixture of quartz sand and petroleum coke. The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond. Its mechancial intensity is greater than fused alumina, but is brittle and very sharp. The mineral has some electrical and heat conductivity. Black silicon carbide is typically used for machining or finishing cast iron ,non-ferrous metals, stone, leather, rubber, and other materials where sharp cutting characteristics are important. The mineral is also used widely as a refractory material or metallurgical additive. More detailed specifications can be supplied on your request.

Q: Who knows about roof fireproofing materials?: Roof thermal insulation materials are various which generally can be divided into two categories, namely inorganic and organic materials: Inorganic materials are expanded perlite, aerated concrete, rock wool, glass wool, etc. Organic materials are styrofoam, polyurethane?foaming?plastic and so on. A. common roof thermal insulation materials 1. the expanding polystyrene board (EPS) has good thermal insulation performance, and cheap price but poor intensity with heat conductivity coefficient of 0.038-0.041. 2. extruded polystyrene board (XPS) has better thermal insulation performance and high intensity but an expensive price with heat conductivity coefficient of 0.028-0.03. It is moisture resistant but needs treatments on surface in construction. 3. rock wool board, with heat conductivity coefficient of 0.041-0.045, is fireproofing, fire?retardant. It has a good hygroscopicity performance but is poor in thermal insulation. 4. gelatine powder polyphenyl granule heat insulating slurry, with heat conductivity coefficient of 0.057- 0.06, has a good flame resistance performance, but the results of recycling and thermal insulation are unsatisfactory. It has high construction requirements. 5. polyurethane foaming material, with heat conductivity coefficient of 0.025-0.028, has good waterproofness and thermal insulation performance, as well as high intensity, but it is expensive. 6. perlite and other slurry, with heat conductivity coefficient of 0.07-0.09, have good flameproofness and water-absorbing ability but are poor in thermal insulation and thermostability.

Q: What are the materials for refractory materials? What are their names?: Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions.

Q: Concrete composition and function of magnesia bond used in refractory: Mainly high purity magnesia powder and silica fume, in accordance with the 4:1 ratio of the mixture, that is, we often use in the castable MgO-SiO2-H2O binding system! Compared with cement, the content of CaO is lower, the high temperature strength of the product is increased, and the slag corrosion resistance of the product is increased!

Q: What's the difference between refractory metal raceway and fireproof raceway?: Fire protection slot won't cause fire accident under the temperature of no more than 200℃. While the refractory cable tray is made with refractory materials and can withstand high temperature of 800℃ with no fire accident happening. The test standard depends on the maximum temperature it can endure. Hope it's helpful for you!

Q: What are the features of construction class A fire resistant door ?: 1, fireproof and thermal insulation Foam cement board is a Class A non-combustible inorganic heat preservation material which has good fireproof?performance can remain integrity after 3 hours baking at 1200℃. It can be used in buildings to improve fireproof?performance.

Q: What things and cement mixed can act as refractory?: This has a lot. I suggest you can check monolithic refractories.

Q: What material is used to make furnace pipe of refractory bricks?: Refractory bricks furnace pipe material is generally divided into two types, namely, shapeless refractory material and shaped refractory. Shapeless refractory material, also known as castable refractory, is hybrid powder material made up of many kinds of aggregate or aggregate and a kind of or many kinds of binders. It must cooperate and evenly stir with a kind or many kinds of liquids during use and has strong mobility. Shaped refractory material usually refers to refractory brick whose shape has standard rules. It can also be proceeded temporarily during cutting according to requirement.

Q: Does anyone know about the A-level fireproof materials?: rock wool external wall composite board, A1-level fire rock wool board, hidden slit rock wool board ? 30, A1-level fireproof mineral wool sound-absorbing board. What about the sound-absorbing sheet? glass fiber acoustic board engineering of the TV backdrop ? 85, A1-level fireproofing and thermal insulation rock wool board is hydrophobic thermal insulation, external wall thermal insulation materials ? 200, high temperature resistant calcium silicate board, LCFC/calcium?silicate?board is A1-level fireproof materials with high-quality and low-price ? 75, the prices above are from the internet for reference only, and the purchase prices vary according to the market.

Q: Does anyone know the fire endurance of steel stud partition?: The fire endurance degree is 1 hour. which is in line with the national building material fireproofing test standards. CaSo4.2H2O is molecular gypsum molecular structure formula, containing 20% ??water, crystal water and free water, when putting on fire, 10% of the surface water will slowly evaporate, remaining10% of crystal water. It is a class A fire retardant material itself. The longest time can be 4 hours.

Q: What are grades of refractory materials?: Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ ~ 1770 ℃, advanced refractories: 1770 ℃ ~ 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.
