good quality metallurgical grade black silicon carbide for metal

Q: What are the use of fire-resistant material and admixture?: I am engaged in admixture and thus familiar. Welcome to exchange!

Q: What kinds of fireproof and fire retardant materials are there?: recommend new Nano-insulation refractory insulation material Aerogel material, which consists of 99% pores of different sizes. it is not only the lightest and the most remarkable insualting material, but also having hydrophobic porous particles. 1830s invention.It has low thermal conductivity,not susceptibale to electrical, thermal and impact of sound with strong physical stability. It is a good insulator, but also has a strong impact resistance, three times the weight of the same volume of air. It is not heavy and can be used as heat insualting materials,buffer?materials, sound proof materials. It has attracted world attention and will be widely used in the future. Aerogel (Aerogel) features: Nontoxic to humans, insoluble in water, no burning, odorless, the world's lightest, low thermal conductivity. Aerogel heat shield is a new industrial insulation products. New products based on nanotechnology materials Aerogel, Aerogel materials in foreign countries has been widely used. We find it a lot better than the traditional insulation materials. To this end, the company introduced the product to China to open the Chinese market and import the best insualting materials to oil refining, electric power, shipbuilding, chemical, industrial pipelines, aerospace, machinery and equipment industries.

Q: Does the external wall thermal insulation materials level b1 need the fire barrier zone?: Residential buildings should meet the following requirements: 1, The height of building is greater than or equal to 100m, the combustion performance of thermal insulation material should be level A. 2, The height of building is greater than or equal to 60m but less than 100m, the combustion performance of thermal insulation material should not be less than the level B2. When using the level B2 thermal insulation material, each layer should set a horizontal fire barrier zone. 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 thermal insulation material, each two-layer should set a horizontal fire barrier zone. 4, The height of building is less than 24m, the combustion performance of thermal insulation material should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone. According to this understanding, it can not be set.

Q: I wanna ask that magnesium oxide is refractory?: Magnesium oxide. magnesium oxide has high refractory insulation properties. After above 1000 ℃ high temperature burning, it can be transformed into crystals. And it can be transformed into dead-burned magnesium oxide or sintered magnesia oxide until rising to above 1500 ℃. It has heat-resistant, non-conductive at room temperature and relatively poor thermal conductivity. Magnesium oxide is mainly used for the preparation of ceramic, enamel, refractory crucible and refractory bricks. I hope to help you

Q: What kind of material is good for cabinet fireproof board: What kind of material is good for cabinet fireproof board What are the advantages and disadvantages of using it? How much is the price? A about how much does one piece cost?

Q: what's the varieties of fire-proof?sealing?material?: Fire blocking material currently on the market include: fire stopping board, foam blocking material, flame resisting module, fire-resisting sealant, flexible organic caulking, WXY-II and fire retardant bag, etc. fire-proof?sealing?material is widely used in building construction and can ensure high-temperature flame and smoke from fires not spread to another fire?compartment, different buildings generally use different sealing methods. Pipeline is generaly sealed by pouring concrete board or mortar.

Q: How to use fireclay?: Mix refractory cement (ie aluminate cement CA50) with some refractory aggregate (bauxite, slag from flint clay) and powder (ie, crushed aggregate). Add some water to the mixture and stir, and it can be used. The clinker can be refractory powder.

Q: What is the concept of lightweight refractory material?: Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.

Q: How many types of fire-resistant material?: 1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.

Q: What are the specifications of fireclay bricks?: 1. The various classification criteria of clay bricks. First, according to the physical and chemical indicators, they can be divided into these types: (NZ) -42, (NZ) -40, (NZ) -38. Second, the classification of specifications of clay bricks is in line with the stipulations in "general shape and size of refractory bricks". Finally, according to the stipulations of relevant state departments, the clay bricks can be divided into standard bricks, ordinary bricks, special-shaped bricks, special bricks. Second, level of refractory temperature of refractory bricks The refractoriness of refractory bricks is divided into four levels according to changes of alumina content. We know that the components in clay bricks include Al2O3. Alkali metals are also included. The refractoriness of AAA-level clay bricks in Ruitai Refractory Material Factory is 1750 ℃; A-level bricks is 1730 ℃; B-level bricks is 1670 ℃; and C-level bricks is 1580 ℃. The softening temperature under a fixed load of Clay bricks is about 1350 ℃. Clay bricks, also known as sintered bricks, are small size artificial bricks for modern architecture. Clay bricks have good properties and high thermal stability, in which Fe2O3 content is less than 2.0 to 2.5%. Overall dimensions: 230 * 115 * 65mm
