Q:Could you tell me the fire-resisting time of class B fire proof door?
The fire-resisting time of class B fire proof door is 1h and thickness of door can't be lower than 45mm.
Q:How to hang the suspended brick in the refractory masonry?
First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.
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:Who knows how many kinds of fireproof insulation materials are there in the market?
Portland cement, insulation stone, calcium powder and platycodon grandiflorum are the main raw materials of inorganic active insulation materials. Advanced manufacturing techniques and chemical Technologies have been used to conduct many tests, thus the close-celled inorganic active insulation materials are successfully developed. Products have advantages of fire-resistance, small deformation coefficient, aging-resistance, stable performance, environmentally-friendly, and good compatibility with rendering coating and subtractive wall, security, stability, and also have a life as long as the building itself. Good fireproofness: The materials of fireproof insulation board are inorganic (cement) which has A1-level fire-resistance, are non-combustible materials, and good at resisting fire. I hope my answer can help you.
Q:What's the A class fireproof and thermal inuslation matertial for external wall?
It is a kind of green and environmental protection inorganic material, free of harmful substances like asbestos, benzene, formaldehyde, etc. Its fire resistance can be up to A1grade non-combustible material, which means it can endure the highest temperature of 1400 ℃. It is thermal insulating with low heat conductivity and high heat storage coefficient. It has good weather resistance, finished product stability, anti hollowing, crack resistance, wind pressure and shock resistance with the same service life as buildings of 70 years. It is water-fast and moistureproof, breathable but waterproof, and fungusproof without influence from steam. It is convenient in construction which omits many procedures of panels construction. Once the second plastering is finished, the construction is completed, which greatly shortens the construction period. It has good adhesive property with various base planes, and meanwhile its external exposed surface can choose coating, facing brick, aluminum sheet, marble, etc. It saves money. Excellent construction technology reduces the construction cost. It effectively prevents the panels from leakage at the external wall, window, eave, etc. which saves the subsequent maintenance fund. It provides timely delivery. With sufficient supplies of raw materials and convenient production, it is fast in delivery.
Q:What are the specifications of fire resistant bag?
Fire resistant bag is featured by wear resistance, resistance to heat, shock, acid and alkali, somke, fire, bacteria, mould and static electricity. Fire resistant bag is generally used for table top, desktop, wall face, cabinet, office furniture, wall-hung cupboard, etc. The common specifications include: 2135mm×915mm, 2440mm×915mm, 2440mm×1220mm, thickness 0.6-1.2mm. I hope it can help you.
Q:Who knows the fire endurance of B-level fireproof doors and windows?
Rock wool board of B-grade fireproof doors keeps 46mm in thickness, doors that are generally used in relatively common fire fighting access, while A-grade fireproof doors are generally used in machine rooms, warehouses, oil depots and other important fire fighting access and flammable and combustible pulbic places. B-grade fireproof doors are more widely used than A-grade fireproof doors.
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:What is the difference between wear-resistant material and refractory material?
Focus is different. Some materials are called wear-resistant and refractory material. For example, refractory castable with high strength and wear-resistance, impressionable plastic material or brick. They all begin with fire-resistance and wear-resistance.
Q:Which are roofing fireproofing material?
(1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
