Product Description
Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips (green silicon carbide production need to add salt) such as raw material through high temperature electric resistance furnace smelting.There is also a rare mineral silicon carbide in nature, and the mo SangShi. Silicon carbide is also called the moissanite. In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic, can be called corundum or refractory sand.At present China's industrial production of silicon carbide can be divided into two black silicon carbide and green silicon carbide.

- Q:The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
- Yes. After moulding by casting in the firing of 1450 ° degrees.
- Q:What are the standards of refractory concrete ?
- Refractory concrete is generally divided into three categories: Light insulating concrete (for insulation); medium-quality refractory concrete (It is used for the parts where requirement of refractory temperature is not very high, and it can withstand a certain erosion of air); heavy refractory concrete (It is used for the parts where requirement of refractory temperature is fairly high, and it can withstand a certain intensity of erosion of air). It mainly depends on the design temperature and the using parts. There are a variety of raw materials, of which aluminum oxide is one of the most commonly used materials, others are alumina hollow ball, magnesium oxide, zircon, etc. It depends on the design temperature and the parts on use. Commercial concrete station generally can not produce it, instead it is compound by professional refractory concrete factories.
- Q:What are the characteristics of magnesium fireproof plate
- Features: Glass magnesium plate is high temperature resistant, sound absorbing, and capable of preventing water, pests, dampness, corrosion, poison, pollution. Paint can directly be applied to the surface of the plate. Air nails are usable for the plate, to which ceramic tile can also be applied with good pigmentation. The plate is easy to decorate, has high strength, good flexibility when bending, and can be nailed, sawed, glued It can also be made into thermal insulation materials with a variety of compround composite insulation plate.

It can be sawed, nailed, and glued.
- Q:What refractory materials are used in power plant
- Vacuum mud machine, sintering furnace! And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
- Q:How to understand qualitative and qualitative refractory materials?
- Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
- Q:Are fire materials poisonous after burning?
- Refractories burning after the smell of toxic, gases are generally silica, alumina, sulfur oxides and so onRefractory material is not less than 1580 degrees of refractoriness, better thermal shock resistance and chemical erosion, low thermal conductivity and low expansion coefficient of non-metallic materials. Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 94% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, thermal shock resistance is poor. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, refractory material, good heat shock resistance, resistance to acid slag, widely used.
- Q:Who knows about the fire endurance of A grade fireproofing glass doors?
- The fire endurance of A grade fireproofing glass doors should be no less than 3 hours. A grade fireproofing glass doors use common glass of 6 mm. The shock resistance of float glass is about less than 5 min, and that of toughened glass is about 15 to 30 min. Fireproofing glass is classified in accordance with fire rating, the fire endurance of which is usually from 30 to120min, and that of the most common fireproofing glass is 60 to 90min, but now the market is a mixed bag, the so-called fireproofing glass is generally fake ultra-strong tempered glass. Therefore, you should buy the genuine glass with formal certificates, or you will bring yourself great inconvenience, and even more serious consequences.
- Q:what is the requirements of roofing insulation materials fire rating?
- The fireproofing requirements of architectural design are regulated by architectural design fire?safety?rules, roofing insulation material only has the requirements of materials combustion performance, namely non-combustible material. No fire rating requirements.
- Q:Which industry does refractory belong to? Does it belong to construction industry?
- I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material?performance. Indeed, there are many places requiring refractory accorded with fire resistant level.
