Q:What kind of flexible fireproof material is really good?
Flexible waterproof materials mostly are asphalt, linoleum and other organic material, which is also called linoleum coiled material waterproof layer. it uses the linoleum, glass cloth fabric as tire layer coil, using all kinds of cementing material phase of asphalt and so on. Make coil bind on roof structure plate leveling layer to form waterproof layer. Flexible waterproof material has high tensile strength, big elongation and light quality, which is convenient to construct. But it has relatively strict operation technology can resistant penetration and aging resistance than rigid materials, aging. Its life is short. Refers to a kind of waterproof material form relative to the rigid waterproofing materials such as waterproof mortar and waterproof concrete. In the form of its and grassroots attached two categories, it includs waterproof coating and waterproofing materials. According to different paste position of waterproof material, it can be divided into outside waterproof waterproof (outsourcing) and inside waterproof (insourcing waterproof) two kinds. Waterproof coil material must be stuck in the grass-roots that have enough stiffness of the. Before pasting, you should apply leveling layer and waterproof layer should be added protective layer of the outside, and need to make the rotation of the flexible material, the processing of subsequent and head closing, in order to ensure the continuity of the waterproof layer and sealing. In addition, there are all kinds of waterproof material and moistureproof coating material.
Q:what's the standard of fireproofing material?
first, the classification of fire resistant levels of buildings, 1, the classification basis of fire resistant levels of buildings, the classification of fire resistant levels of buildings is one of the basic building fire protection technology measures, our national architectural design specification divides fire resistant levels of buildings into first, second, third and fourth class, first class ios the highest and has the most strong fire-resistant capacity, fourth class is the lowest and has the weakest fire-resistant capacity. Fire resistant level of buildings depends on the combustion performance and fire endurance of the components of the buildings. construction components refer to the wall, base, beam, column, floor, stair, suspended ceiling and other basic components of buildings. Combustion performance and fire endurance of building components are shown in table 4-11), the combustion performance of building components are divided into non-combustible component,hard-comnustible component,combustible component,according to their response to the fire. as for building components, non-combustible component includes wall column and base,etc; hard-comnustible component includes hanging bracket, suspended ceiling and internal pipe;combustible component includes doors and windows, suspended ceiling, decoration materials,etc.
Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
fireproofing glass is mainly control the spread of fire or smoke insulation, and is a measurable fireproofing material, the fireproofing effect is evaluated by the fire resistance. It is through a special process and treatment, and it is a special glass which can maintain its integrity and thermal insulation in the specified fire resistance test. Original glass of fireproofing glass can be used float flat glass, and composite fireproofing glass also can use monolithic fireproofing glass.
Q:Refractories for iron-making blast furnace?
Vibrating materials, corundum brick and aluminum carbon brick will be developed. Taphole commonly use stemming, silicon carbide - graphite bricks, whose material is Al2O3-SiC-C. Medium and large sized blast furnaces in China use dense mullite bricks, castable, graphite brick. Common lining material for iron ditch is ramming mass. hearth and furnace bottom common use carbon bricks, semi-graphite bricks, charring silica bricks, corundum bricks. Blast furnace bosh and lower part of furnace stack commonly use mullite bricks.
Q:Which schools are the best schools in the world for learning knowledge about refractories?
If you search on a worldwide scale, I might say you are ambitious!!! This major becomes an unpopular one and you must have to embark on graduate and PhD to specialize in it provided that you want to go abroad for further study. Wuhan University of Science and Technology may be the best school in this field with its close relatinship with many refractory manufacture factories across the country. Henan University of Science and Technology is also advisable in terms of this major, which probably promise you a job. Other universities in this regard are not quite familiar to me. You raised these questions, which shows that you are a layman to this major or not quite familiar with this major. If you have any questions, you can resort to me if I can.
Q:what is the grading standards of external wall thermal insulation materials?
What is the grading standards of external wall thermal insulation materials? summarizing the three versions of GB8624 (1997,2006,2011) external wall insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. the dividing is based on many technical indicators. It takes time to explain for It is professional and technical. For details, please contact Qingdao Shan Textile Instrument. they specialized in external wall insulation fire rating tester.
Q:How to choose the material of refractory?
Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
Q:Could you tell me how does fire protection standard of decorative material is divided?
Building materials can be divided into four levels according to combustion performance (non-combustible, flame retardant, flammable, flammable). According to the Code for Design on Building Fire Protection and Prevention (GBJ16-1987) (revised in 2001):, the fire risk of production or storage is divided into a, b, c, d, e classes. Divided by plate material: structure material, base layel materials and fabric; Divided by fire protecrtion type: easy to burn, difficult to burn, flame retardant, incombustible material. Material has no fire rating, only the different from the time of combustion limit. Combustion performance grade A of commonly used adornment material: granite, marble, terrazzo, cement products, concrete products, gypsum, lime products, clay products, glass, ceramic tile, Mosaic, steel and alloy. I hope my answer can help you.
Q:What are the characteristics of magnesium fireproof plate
Plate glass magnesium fire with high temperatures, flame retardant, sound absorption, shock-proof, pest control, anti-corrosion, non-toxic tasteless non-polluting, can be used directly on the painting, direct veneers, available gas nail directly on the tile, the surface has good coloring , high strength, resistance to bending toughness, nails, saw, can be sticky, easy decoration. It can also be made into thermal insulation materials with a variety of compround composite insulation plate.
Q:How many hours of the fire endurance time of the rock wool laminboard?
Hello. The fire endurance now on the market is generally about two hours. The 50mm color steel sandwich version of Bo magnesium rock wool, with refractory time being five or six hours, is very good.
