Q:What are grade classifications of the external walls for fireproofing?
The classfication of external wall material fire rating is as follows: Level A: Complete retardant building materials may not occur combustion, and the cost is relatively high, home decoration do not need such a high standard. In general, it can be used in the arms powerhouse and electrical appliance store. Level B1: non-flamble construction material has high flame-retardant, it will not be burn under the conditions of open fire and high temperature, but if it is attacked by these two conditions, it may still be burning. However, when the source of fire is transfered, it will be immediately extinguished. Level B2: Combustible building materials have a certain degree of flame resistance, but the effect is very little. Under the condition of sufficient air, it will break out fire even in high temperature, such as wood building materials. Level B3: As long as the flammable building materials meet the source of fire or high temperature, it will break out fire. Currently, this product doed not sale on the market. So what are the external wall thermal insulation fireproofing materials? According to several grades, I will give you some specifical examples. Level A insulation material: Glass wool, foam glass, foam cement, hole-closed perlite, rock wool; level B1 : Extruded polystyrene board through special processing, referred to xps. The other is polyurethane through special treatment, referred to pu. In addition, there are phenolic aldehyde and gelatine powder polyphenyl granule; level B2: Polyethylene, referred to pe. Molding polystyrene board, referred to as eps.
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:How to distinguish the fire rating of rubber and plastic thermal insulation material?
Fire rating grading of external wall thermal insulation materials. 1, China's national standard GB8624-97 divides the combustion performance of building materials external insulation materials into the following grade. Level A: Incombustible materials: Almost no burning materials. Level B1: Incombustible materials: Flame-like material has good fire-retardant effect. In case of fire in the air or at high temperature, it is difficult to fire and doesn't spread quickly, and when the fire source is removed after combustion, it stops immediately. Level B2: Incombustible materials: Combustible materials have a certain flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily leads to the spread of fire, such as poles, wooden frame, wooden beams and wooden stairs,ect. Level B3 : Incombustible materials: No flame-retardant effect, hidhly flammable and high fire risk. 2, The external wall thermal insulation materials could be divided according to the fire rating. 1) thermal insulation material that has the level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2), The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3), Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU) and polyethylene (PE), etc. The information given is for reference only. Hope it will help you.
Q:what needs to be noted when choosing and using blast furnace fireproof materials?
Hello,: three parts of the blast furnace lining in general are easily corroded. The first one is furnace bosh,second is the middle part of the furnace, The third is lower part of the furnace stack. if These parts are damaged, then we need an overhaul. Bosh, because damage to the middle part of the furnace and the furnace bosh are generally due to alkali metal and fusant erosion. the main reason for the lower furnace part damage is molten iron, slag. In view of this situation, mullite bricks, corundum bricks, silicon carbide bricks are used for reparation. make repairments as soon as possible if any problems occur in case of incidents.
Q:What's the organzational structure of refractory material?
Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
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. Scheme One of gypsum board partition system by using 75# series of lightgage steel joist: separation distance of keels keep 600mm in vertical direction. The thickness is greater than 0.5mm; gypsum board: it shoule be the board of double-sided and single-layer with the thickness of 12mm. Fire-resistant gypsum plaster board's fire-resistance limit: 1 hour. Sound insulation index: over 35 rwdb.

Q:Which industry does the metallurgy and thermal insulating and refractory material belong to?
Building Materials
Q:Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance includes unexposed surface temperature rise, its fire endurance should not be less than 3 hours. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.
Q:Does refractory belong to stone, building materials or other?
Refractories belong to organic non-metallic materials, stone and construction materials. After it is used in building. Just for your reference.
