2.Main Features of Silicon Carbide
Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and has a certain degree of electrical and heat conductivity.
3.Main usage of the Silicon Carbide
1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials
2.Bonded abrasive tools, lapping and polishing
3.Widely used as a metallurgical additive and refractory material

6.FAQ of Silicon Carbide
1). Q: Are you a factory or trading company?
A: We are a factory.
2). Q: Where is your factory located? How can I visit there?
A: Our factory is located in Ningxia, China. You are warmly welcomed to visit us!
3). Q: How can I get some samples?
A: Please contact me for samples
- Q:What parts of cement kilns are refractories used on?
- These parts are decomposition furnace, smoke chamber, kiln, kiln hood, grate?cooler, tertiary air duct and coal pipe.
- Q:How to use fire-resistant soil?
- In fact, the refractory soil is not strong. Refractory soil is clinker, there is no strength, also known as "blade mud", he is used as filling materials, the use of thickness generally not more than 3mm. Therefore, the furnace insulation can not be done.Civil boiler interior insulation, you can use "high aluminum cement", also known as refractory cement on it.
- Q:Does the aluminum silicate thermal insulation material fireproof?
- With stable performance,long fiber length, strong tensile strength, strong seismic performance, low shot, light unit weight, low thermal conductivity, good insulation properties. it is not bad.
- Q:Can anyone tell me the requirements of the refractory masonry?？
- Refractory materials actually have two functions. The first one is to improve the refractoriness and the second one is to improve the body plasticity of refractory materials.The higher the aluminum content is, the better refractory it will be. Of course, the content of aluminum in refractory materials can not be impoved only by using kaolin. Such raw materials that contain more aluminum as bauxite chamotte should be used as framework.So the content of aluminum in kaolin does not need to be too high and more than 38% of aluminum is enough. However, the viscosity should be taken into account. It will be better if the viscosity is better as the extra bentonite do not need to be added.The refractoriness that is is above 1400 degree is enough.
- Q:As for fireproofing material rock wool and glass wool, which one is better?
- First of all, glass wool and rock wool fireproof materials, rock wool and glass wool belong to Class A fireproofing rating, secondly, rock wool can endure high temperature of 800 degrees, glass wool high temperature of 450 degrees, again,unit weight of rock wool is relatively heavier and unit weight of glass wool is lighter, finally, glass wool has better waterproof performance.
- Q:How is the division of the fire resistant level of the rock wool board?
- The fire rating of European style rock wool board is level A , which uses Da Guang Beijing Jinyu rock wool board, with the main advantages are: 1, High acidity coefficient: The high coefficient of acidity greatly improves the life resistance and weather resistance of the rock wool board. 2, Hydrophobic air permeability: According to the picture, Jinyu Star rock wool is water-repellent, at the same time it also has breathability, so the liquid water is not easy to dip into the rock wool, and the water vapor and other gas molecules could pass through the rock wool. In particular, the insulation materials have this feature which enables the building to have "respiratory function" thus making the room more comfortable and preventing anti-mildew phenomenon happening indoor. 3, Environmental protection: The goldfish can survive freely, which just shows it is environmental; 4, High strength: The advanced pleating and curing technology make the rock wool board tensile and high compressive strength. It not only can be applied on the external wall thermal insulation and sandwich board core material, but also can be used to make structural cotton in the flexible waterproof roofing. Its quality is so stable that it is convenient in construction and durable in use. 5, Fireproofing: Not just talking about the fire rating, but the fireproofing time, which is generally up to two hours, and can be used for lining thermal insulation fire-resistant part of the glass curtain wall, through-wall pipe seal, pier?between?two?windows, window sill wall and other parts; 6, Derived advantages: Agriculture applies the soilless cultivation cotton;
- Q:What a blast furnace refractories generally?
- refractories for blast furnace include carbon brick and silicon-aluminum refractory. BF carbon brick inlcudes half-carbon charcoal bricks, microporous charcoal brick, ultra porous charcoal bricks, graphitic brick and mould pressing charcoal brick. tiles and molded graphite small charcoal bricks. I hope my answers above are helpful to you and your ideal anwers.
- Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
- it has fire resistant level, incombustible?material,and it should reach grade one level.
- Q:What advantage and disadvantages it has compared to common fire insulation materials
- Main advantage of A-level fire proof heat retaining plate is A-level non-conbustibility. Now residential areas strictly require the external walls to be high-level fire proof, to be specific, high fire resistance, non combustible. Standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. Disadvantage is the insulation effect is quite ordinary. It will absorb water, get deformed, need some water prevention measures after constrcuting thermal insulating layer for it. Its thermal conductivity far below the benzene plate, and plastic extruded palte, half the thickness of the polyurethane insulation layer can reach heat perservation effectiveness of the benzene plate and extruded plate of the same thickness.
