Q:what is the fireproofing material of engine room? who knows it ?
1. The new type fire retardant coating in fire retardant coating, the expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder, etc. These inorganic component, is a major part of the thick coating type of fireproof coating, and they also are the major factor affecting the level of performance of fireproof coatings. The fireproofing thermal insulation properties of fireproof coating, is mainly determined by the fire back surface temperature of this factor, but also related to the fire endurance. If it reaches the same temperature for a longer time, it shows that it's fireproof thermal insulation is better, and the fire endurance therefore is higher. 2. The new fireproof board new fireproof board now is welcomed by the people and the important factor is its environmental protection, and with the increasing high-rise buildings, the fire protection requirements and strength requirements are also rising, it is a big challenge for the performance and standard of the fireproof board.. Now fireproof board is mainly used siliceous material or calcareous materials, and then mixed with the fiber material, lightweight aggregate, adhesives and chemical additives, it is not only be fireproofing, but also improve their thermal insulation performance, and light weight, good carrying capacity, good durability, no aging problem, more importantly, it is good in environmental protection.
Q:What is the common inorganic fireproof and thermal inuslation matertial?
Ceramic foam insulation board is made from clay tailings, ceramic broken flake and river silt, which is the closed ceramics material with high porosity roasted in high temperature by advanced production technology and foam technology. Products have fire retardant, small deformation coefficient, aging resistance, stable performance, good environmental protection, good compatibility between wall base and plastering layer, good safety and soundness and a lifetime as long as the building itself.
Q:How to deiron refractory?
Deironing refractory can take physical methods into consideration, such as magnetic separation, reselection, etc. And it can also take chemical methods, such as flotation.
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 types does soft fire prevention materials have?
Soft type fire resistant species. Finishing fire retardant paint, component fire retardant coating, fire-resistant coating for steel structure and othe kinds of fire retardant coating. Flame retardant plastics and its products, textiles, building materials, flame retardant fabric and exterior wall thermal insulation system products, floor materials, such as various types of fire prevention materials;Fire prevention board, fire doors, fire prevention, fire shutter, fire glass window frame, elevator doors, ventilation pipes, fire blocking material, fire smoke exhaust fan and other kinds of artifacts (resistance) fire prevention.
Q:what's the fireproof levels of fireproof and thermal inuslation matertial?
at present,thermal insulation and fireproofing materials on the market include inorganic thermal insulation bead board(Shanghai Benniao construction and energy saving decoration materials company) rock wool (Hebei Shenzhou glass wool products co., LTD.) foamed glass ceramic (Nanjing Institute of Building Research) or sogou search.
Q:I want to consult the fire resistant level standards of external wall thermal insulation materials.
1, The building with the height larger than or equal to 100m, should have the A-level combustion performance. 2, The thermal insulation material of the building, with a height larger than or equal 60m and less than 100m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each level should set horizonal fire barrier zone. 3, The thermal insulation material of the building, with a height larger than or equal to 24m and less than 100m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each two levels should set horizonal fire barrier zone. 4, The thermal insulation material of the building, with a height less than 24m, should not be less than the level B2 combustion performance. When using the level B2 insulation material, each three levels should set horizonal fire barrier zone. I hope my answer will help you. Thank you!
Q:What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?
Insulation materials. Thermal insulation material is characterized by thermal insulation, which is one of the four traditional inorganic nonmetallic materials. Fire retardant material is cahracterized by heat-resistant. Refractory is a kind of materials of resisit high temperature. Fireproof material, which is different from thermal insulation material and refractory, is a synthetic material with some fireproof subtrate added. It is essentially resistant to high temperature.
Q:What is the fire endurance of ceramsite concrete blocks?
The heat conductivity coefficient of grade 800 hollow building blocks in ceramsite concrete is 0.23 and fire endurance is 4h. Ceramsite concrete has strong construction adaptability. It can not only compound concrete material with different unit weight and strength(It changes with the structure of thermal insulation or bearing structure) according to the different purposes and functions of buildings, but also is easy to construct. It is suitable for industrial production of a variety of construction methods. It can not only make all types of components(board, block, girder, column, etc) by using production process, but also can use mechanization construction of cast-in-place. The strong adaptability of construction of ceramsite concrete is not comparable to any other lightweight building materials(such as air-entrapping, etc.).
Q:What is the difference in the nature between the refractory material and thermal insulation material
thermal insulation material is a material which has a strong impedance to the heat flow. the nature of the material requires that the material can isolate the delivery of thermal, and the low heat conductivity coefficient and expansion coefficient of the non-metal material.refractory is good in heat resisitance and chamical erosion but not high temperature resistance. Requirements on nature is still in high temperature.
