Q:How should fireproof building materials be ranked?: Division of fire-proof grade of buildings is one of the most basic measures in the fire-fighting technology and measures of buildings. According to our national code of building design, fire-proof grade of buildings are classified into four levels of first, second, third and fourth, of which the first level is the highest in fire resistance and the fourth level is lowest in fire resistance. Fire resistance rating of buildings depends on the combustion performance and fire endurance of the building component. The so-called building component refers to the walls, foundations, beams, pillars, floors, stairs, ceilings, etc.

Q:How to count the construction costs of refractories?: In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric?acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.

Q:What kind of refractory materials are used in metallurgy industry?: Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.

Q:Who knows what material is in the center of fireproof rolling curtain?: made of inorganic super fireproof rolling curtain: Glass fiber cloth ceramic fiber cloth (reinforced stainless steel wire) ceramic fiber blanket aluminum foil cloth. Hope my answer will help you.

Q:What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?: The combustion performance of materials could be divided into: A( noninflammability), B1(flame retardancy), B2(flammability), B3(inflammability). Building materials are divided into four ranks according to these properties. 1. In accordance with Code for Design of Building Fire Protection(GBJ16-1987)(revised edition in 2001), fire hazards in producing and storage can be divided into five types. In Fire Prevention Code of Petrol Chemical Enterprise Design(GB50160--1992)(revised edition in 1999), classification of fire hazards is also achieved according to the hazards of materials that have been using, producing and storing. Measures in prevention of fire explosion could be taken from the perspectives of fire separation, fire resistance level of structures, allowable floors, safe evacuation, and fire extinguishing facilities based on different levels of fire hazards. 2. Four fire resistance rating of buildings are listed in the book Code for Design of Building Fire Protection. And specific stipulations are made to the fire resistance of main elements of buildings, such as bearing walls, beams,pillars, and floors. When designing a building, if permitted, refractory materials of high-rank should be adopted in those buildings which have high potential fire hazard and a lot of combustible material and valuable equipment. While making sure fire resistance rating, the duration of fire resistance of each elements should meet its requirements.

Q:Is fireclay corrosive?: No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.

Q:What effect does aluminium powder play in refractory bricks?: Aluminum powder can increase the high melting point of refractory refractory, while increasing material density, hardness and other changes in physical properties of aluminum powder in the application of unshaped refractories in the gas can be discharged in the material, prevent the refractory sudden warming occurred during the burst.

Q:What is the importance of silicon powder in refractory processing?: in amorphousness it is mainly the mobility

Q:How to distinguish the fire resistant level of construction materials?: Division of fire resistant level of building material: 1, It can be divided into five levels according to the importance: a, special class: commerative, historic, international and national buildings. b, Class A: high-grade residential architecture and public building. c, class B: middle-grade residential architecture and public building. d, class C: orinary residential architecture and public building. 2, It can be divided into four grades according to fireproof?performance: Fire resistance level buildings is divided into four levels. Standard of fire resistant level is based on the combustion performance and fire endurance of main components of the house. 3, It can be divided into 4 levels according to durable life: a, A grade durable life, over 100 years, for important buildings and high-rise buildings. b, second level durable life, from 50 to 100 years, for ordinary buildings. c, third level durable life, from 25 to 50 years, for secondary buildings. D, fourth level durable life, less than15 years , for temporary buildings. I hope my answers will help you.

Q:Is aluminium oxide refractory material?: Yes. It has high melting and boiling point, stable chemical?property. All refractory material almost contains aluminium oxide. Refractory materials have a large range and need specific requirements. Refractory material is divided into sizing refractory material, shapeless refractory material, ceramic fiber, refractory bricks and castable refractory. It can be subdivided according to temperature rating. Hope it is helpful to you.
