Q:Fire rating of decoration materials
code for fire protection design of buildings
Q:Does anyone know about the A-level fireproof materials?
A1-level fireproof materials include: 1. inorganic materials: glass wool, rock wool, foam glass,etc. 2. organic materials: phenolic foam insulation composite board. I hope my answer can help you.
Q:What is the common inorganic fireproof and thermal inuslation matertial?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), sea capacity module and vitrified micro bead. (Hope I can help you! Hope you adopt. Thank you! )
Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
Q:What are the raw materials of refractory concrete ?
Q:How to choose construction external wall thermal insulation and fireproofing materials?
The width of fireproof partition shuld be greater than 30CM, and the thickness should be the same as total thickness of thermal insulation materials. Fire barrier zone thermal insulation board and base wall should be stuck in whole area. Fire Barrier zone thermal insulation board should be stuck with the assistance of anchor bolt which must press the mesh of the bottom layer. Fire Barrier zone should be set above the door and window, with a distance of less than 50cm between the lower edge of fire barrier zone and the upper edge of window.
Q:how to divided the external wall thermal insulation materials fire rating
The external wall thermal insulation materials is divided by fire rating: 1. The thermal insulation material of level A combustion performance: inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:How should fireproof building materials be ranked?
5. Civil building 5.1. Fire resistance rating, number of layers and floorage of civil buildings 5.1.1. Fire resistance rating of civil buildings should be classified into four levels of first, second, third and fourth. Unless otherwise specified in the code, the combustion performance and fire endurance of building components with different fire resistance rating should be no less than that of the regulations in Table 5.1.1. Table 5.1.1: Combustion Performance and Fire Endurance (h) of Building Components (Figure) Note: 1. Unless otherwise specified in the Code, the fire resistance rating of the building with wooden pillars as load-bearing and incombustible material as the building wall should be the fourth level; 2. For the suspended ceiling of the building with the second level of fire resistance rating, if it uses non-combustible component, it won't be limited in its fire endurance; 3. For buildings with the second level of fire resistance rating, if it is really difficult for the partition wall of rooms with the area of no less than 100m2 to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.3h; 4. For buildings with the first or second level of fire resistance rating, if it is really difficult for the partition wall of both sides of the evacuation walk to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.75h. 5. Fire endurance and combustion performance of the residential building component can be implemented in accordance with the provisions of current national standard GB 50368 "Residential Building Code".
Q:Are refractory materials and fireproofing materials the same?
Refractory materials is flammable when it is reached certain temperature for a certain time, but it will not support burning when there is no open fire (such as: gypsum board). Fireproofing material reaches A grade and it is non-combustible itself.
