Q:Fire rating of decoration materials
You can refer to (code for fire protection design of buildings)
Q:How to classify fire resistance rating of brick-concrete structure?
In order to ensure the safety of the building, the fire protection measures must be taken to make it have a certain degree of fire resistance, even if there is a fire, it will not cause too much damage. According to the national conditions of our country, and in the light of other countries standards, < high-rise civil building fire protection design specification > defines fireproof rank of high-rise civil buildings into level one and two; < code for fire protection design of buildings > divides the rank into level one, two, three, four, level one is the highest level, level four is the lowest. Besides that the minimum fire resistance of the building component is specified, buildings of fire resistance rating also specified requirements for combustion performance. Because the component with the same fire resistance limit is different, it is different in the fire.According to our country national standard < building design fire protection code >, the fire resistance rating of the building is divided into four levels. The fire resistance of a building is determined by the combustion performance and fire resistance of building components (such as beams, columns, floors, walls, etc.). Generally speaking, the fire resistance building of level one is a mixed structure of reinforced concrete structure or a mixture of brick wall and steel concrete structure; the fire resistance building of level two is a mixed structure of steel truss structure, reinforced concrete column and brick wall; the fire resistance building of level three is brick-wood structure made of wood roof and brick wall; the fire resistance building of level four is combustible structure which is composed of wood roof and non-combustible wall.
Q:What kind of material is refractory bauxite?
Bauxite in refractory industry usually refers to the calcined bauxite ore which contains Al2O3 no less than 48%, while the content of Fe2O3 is rather low. Clinker of bauxite with high alumina is calcined bauxite. Tghe clinker is grey, light yellow and dark gray.
Q:What are the qualifications of refractory industry?
Certificate for production and sale is needed, just like the certificate for other products.
Q:Why should graphitic refractory materials be used now that graphite can burn?
Materials for refractory must have the following characteristics and properties: 1, high stability: Anti-oxidation, anti-reduction, thermal decomposition; 2, high melting point : 2800℃; 3, low price. Graphite has all three characteristics and properties, especially melting point and stability.
Q:Does the aluminum silicate thermal insulation material fireproof?
How does its fireproof performance? this is the material that the decoration master worker recommands to me, how do you think of it?
Q:How long can gypsum board endure fire?
General gypsum plaster board with a thickness of less than 12mm has a fire endurance which is less than half an hour. It is clearly stipulated in Clause 2.0.4 of "Specification of Fire-resistance of Decoration Design in the Interior of Buildings" that "gypsum board, mineral wool board and acoustic board whose combustion performance reach at B1 grade installed on steel joists can be used as A-grade incombustible materials. Although the gypsum board is non-combustible material, we need to examine materials' stability in the face of fire and their fire retardant limits besides exmine their fire prevention standards. Fire retardant limit refers to the ability and time that materials can resist fire when encounting fire and taking palce changes.
Q:How long is the fire endurance of fire resistant rolling shutter door?
According to the requirements of Building Regulations 7.5.1 article,the fire endurance of class A fire resistant rolling shutter door should be no less than three hours.
Q:What are the fire resistance ratings of the glass partition?
Hello, friend. The glass partition system is composed entirely of metal structures, glass, color plate and other materials which also has fire resistance capacity. When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer.
Q:What are the advantages of refractory material?
Jingute WHL type, GDS type
