Q:The difference between refractory and thermal insulation material
Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.
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 are the materials for refractory materials? What are their name?
Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% 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, low thermal shock resistance. 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, heat shock resistance, resistance to acid slag, widely used.
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:What are the technical requirements for refractories?
How high the temperature is and what is this refractory?
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:What are the uses of refractory materials of glass furnace?
crown--high-purity silica bricks; wall--melting end 41# fused zirconia corundum bricks with no shrinkages(41% of zirconium, similarly hereinafter), cooling end 33# fused zirconia corundum bricks with no shrinkages; bottom--33# fused zirconia corundum bricks(with shrinkages); breastwork--33# fused zirconia corundum bricks(with shrinkages); port--33# fused zirconia corundum bricks(with shrinkages); regenerator chamber--the upper part is for magnesite-chrome bricks, the bottom part is for high-duty fireclay bricks; checker--the upper part is for high purity magnesia bricks, and the bottom part is for magnesite-chrome bricks; flue--clay bricks. This is the best configuration. If the funds are limited, the configuration can be lowered, for example, the wall will be changed to 38 #......
Q:What is the difference in the nature between the refractory material and thermal insulation material
thermal insulation material is used to thermal insulation and the transfer of heat insulation. refractory material is defined as greater than 1580 ° non-metallic materials, such as calcium silicate board. its using temperature can reach to 1100 degrees, and some can also be used at high temperatures, and all high-temperature industrial can't be oprated without it, and the using temperature of polycrystalline alumina fibers can reach to 1800 degrees
Q:What kind of fireproof material is used for steel structure?
Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities. Agglutination material are classified as fireproof coatings for steel structures which is solvent based and Water-based steel structure fire retardant coatings. Fireproof coatings for steel structures which is solvent based are subdivided into fireproof coatings for steel structures which is solvent based with low benzene content and fireproof coatings for steel structures which is solvent based with high benzene content (TVOC≤600g / L, benzene ≤5g / kg). It can be divided by thickness. ultra-thin (CB) fireproof coatings (coating thickness ≤3mm), thin (B) fireproof coatings (3mm & amp; lt; coating thickness ≤7mm) and thick (H) steel structure fire retardant coating (7 mm & amp; lt; coating thickness ≤45㎜). The coating can be divided into non-intumescent fire retardant coating and intumescent fire retardant coating according to the the expansion properties. Slim (CB) and fire-resistant coating for steel structure and thin(B) fireproof coatings is intumescent fire retardant coating, thick (H) fire-resistant coating for steel structure is intumescent fire retardant coating. Unprotected steel structure has fire endurance of 0.25 hours.
Q:What is unshaped refractory?
Plastic. From the production method, the plastic is between the concrete and the castable. It is made of refractory material by refractory material plant, which is made of plastic clay. The ingredient is a retarder. It is packaged by plastic bag, and construction and heat treatment are carried out on the spot. But the biggest problem is the application of plastic on the knotted Jiecha easy peeling, retarder dosage improper or is vulnerable to bad caking plastic hardening.
