Q: Can anyone tell me what is A-leve fireproof material?: Combustion performance of materials can be divided into: A-level, B1-level, B2-level and B3-level, which respectively refer to noncombustible, difficult-flammble, flammable and inflammable materials. Building materials can be divided into four grades based on combustion performance (noninflammability, flame retardancy, flammability and inflammability). According to the stipulation of "Specification of Fireproof Design for Buildings" (GBJ16-1987) (2001 revised edition), fire hazard of production or storage should be divided into A-level, B-level, C-level, D-level and E-level. In "Specifications on Fireproof Design for Petrochemical Enterprises" (GB50160--1992) (1999 Revision), it also stipulates that fire hazard should be classified on the same basis of subtsance danger in usage, production or storage. According to different fire hazard, requirements and measures of oreventing and restricting fire explosion can be put forward from the aspects of fire?separation distance, fire resistant rating of buildings, allowed floors, safe evacuation, fire fighting facilities and other aspects.

Q: What is streaming fireproof material?: Since streaming fireproof material has less surface energy, so when it is placed in a location to be used, it can be automatically filled so long as mixed with water at proper ratio. And then using vibrator or vibrostand and other tools to compact the mixture so as to satisfy the use requirements. Therefore, it does not require vibration, and it has less friction force between the particles. Generally hydraulic refractory castable must be mixed with water at proper ratio when in construction . While, the concept of "streaming" is in terms of refractory castable.

Q: How about the prospect of refractory material?: Due to the rise of raw material, the prospect is not good with inflation, lower prices and decreased profits. The product requirements have been enhanced and there is vicious competition. Therefore, it is really bad.

Q: What kind of material is good for cabinet fireproof board: Cabinet fireproof plate can be classified into fiber cement fireproof board, metal fire proof board, mineral wool fireproof board, perlite fireproof board, all sorts of fire prevention board. Fiber cement fireproof board is a kind of ornament plate using siliceous or calcareous as main materials and combined with a certain proportion of fibre material; metal fireproof board is a kind of decorative plate made of aluminum plate, stainless steel plate, color steel plate and other metal materials as the main raw material and added by certain flame retardant materials. Mineral wool fireproof board is a decorative plate made of mineral wool and glass wool; perlite fireproof board is hollow fire proof plate made of low alkalinity cement as the main raw material, and supplemented by certain perlite with fireproof function as filling. Fiber cement fireproof board is a kind of new material increasingly gets popular with superior heat insulation, sound insulation performance, belonging to the A1 level fire materials 1, Suzhou total surplus purification A-grade fireproof rock wool colored steel rock wool board range of applications: Partition ceiling material: Rock wool reference price: On a square 58.00/2 meters, Huarui thermal insulation fireproof materials aluminum silicate refractory aluminium silicate A-grade fireproof heat insulation aluminium silicate plate temperature: 1000 core material: Reference price for aluminum silicate fiber cotton: $3500.00\ ton

Q: How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?: The relative production is lower and material cost is higher, the lining of the refractory is thicker: 1, determine the weight of the refractory material according to the main structure of the bearing capacity, to prevent damage to equipment, fire-proof material damage after the surplus size and thickness of the thermal conductivity of refractory materials, the smaller the effective volume, production output, the cost of materials) to consider the selection of refractory material thickness. 3 from the point of usage (usage cycle, relative usage cycle is longer, because under the condition of invariable in the device's overall dimensions of the refractory lining thickness to determine several basic principles, according to the volume of the weight computation of refractories and refractory thickness, these items must be fully consider the pros and cons before decided. 2 according to maximum temperature that shell can withstand.

Q: What is the strength of high strength refractory material?: With the help of high temperature and load, refractory material deforma to a certain degree of temperature from the beginning of deformation (load softening point), known as high temperature structural strength or high load softening temperature. It is a the ability to resist deformation ih high temperature and load at the same time. The nature of the high temperature is very improtant for selection of a furnace building materials under the effect of high temperature and force.

Q: Who knows the classifications of magnesia refractory?: Magnesia chrome series products: The main ingredients of magnesium chromium series are MgO and Cr2O3. Periclase is the first phase and magnesia-chrome spinel is the second phase. Products belonging to this series are magnesium chrome brick and chrome magnesia brick. The main ingredients of magnesium aluminum series are MgO and Al203. As they generate MgO and Al203, all magnesium chromium series products contain magnesia material. magnesium calcium series products The main components are MgO and CaO. They have high melting points, which are important magnesia materials. 5, magnesium silicon series products: The main component of magnesite series is SiO2, when the C / S<5, SiO2 and MgO generate MgO.Al2O3 (forsterite). From the perspective of microscopic mineral, main products of pure aluminum series include magnesium aluminum brick, periclase spinel brick, corundum spinel brick and aluminum-spinel castable in unshaped materials. I hope this answer can help you.

Q: What are the requirements of the performances of brasque refractory?: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down But only refractoriness can not fully describe the refractories, 1580 ℃ is not absolute. Refractory is now defined as material of physical and chemical properties allowing to be used in high temperature environments. Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.

Q: how to divided the external wall thermal insulation materials fire rating: Level A: Incombustible building material is a material that does not occur any burning. Level A1: Noncombustible means no open fire. Level A2 It is noncombustible, and should measure smoke to be qualified. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: inflammable building material has no any flame resisting effects, and is easy to burn, so the fire risk is high.

Q: Where do China and foreign countries do more refractory materials?: Zhengzhou real gold refractory materials Co., Ltd. specializing in the production of non-ferrous industries, glass kilns, cement kilns with a variety of refractory materials, factory direct sales, reasonable prices.
