Q:How should fireproof building materials be ranked?
Division of fire-proof grade of buildings is one of the most basic measures in the fire-fighting technology and measures of buildings. According to our national code of building design, fire-proof grade of buildings are classified into four levels of first, second, third and fourth, of which the first level is the highest in fire resistance and the fourth level is lowest in fire resistance. Fire resistance rating of buildings depends on the combustion performance and fire endurance of the building component. The so-called building component refers to the walls, foundations, beams, pillars, floors, stairs, ceilings, etc.
Q:What's the heat conductivity coefficient of fire-resistant material?
There are many types of fire-resistant materials woth different thermal conductivity. The question should be more specific.
Q:What parts of cement kilns are refractories used on?
These parts are decomposition furnace, smoke chamber, kiln, kiln hood, grate cooler, tertiary air duct and coal pipe.
Q:What are the chemical composition of refractory cement?
Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
Q:Which manufacturers have the best fire-proof materials with light weight?
It now appears that asbestos is the best among the most common fireproof materials. But asbestos also has great harm, especially to lung. Shanghai Xinlong Fireproofing Material Co., Ltd. and Hubei Boyue Lightweight Material Co., Ltd. were established in 2009. The company is located in Wuhan Biological New Town and covers an area of ​​30 acres. The company is a specialized enterprise which is mainly engaged in the research and development, production, sale and construction of lightweight partition board, lightweight fireproof wall panel and lightweight wall panel. The two companies are both good.
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:Is there requirement for radiation indicator in refractory?
All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
Q:What is the fireproofing requirements of external wall thermal insulation materials?
in the 2011 and 2012 revised version of "Fireproof  Specification of Building Design" in China, the external insulating layer of above 50 meters (approximately 16 layers) of the housing must use the level A material. The latest draft for approval is not so strict, above 100 meters (about 33 layers) only use level A material. The manuscript of "Building Regulations" is also regulated building's external wall thermal insulation materials in the crowded places should be level A. Except the residential buildings and the buildings in the crowded places, the height of other buildings is greater than 50 meters, combustion performance of insulation materials should be level A; the height buildings is greater than 24 meters but not more than 50 meters, combustion performance of insulation materials should not be lower than level B1. "Building Regulations" manuscript should relax the rules on the aspect of protective coating in level B1 and B2 insulation material. The outer of level B1 and B2 level insulation material must use incombustible material as protective coating, its thickness is changed from the original 10 cm to 5 cm. Given certain conditions, I feel you can use TDD exterior wall thermal insulation decoration integrated rock wool board for construction, which is level A fireproofing with a short construction period and good thermal insulation properties. I hope I can help you!
Q:What's the requirements of fire-fighting criteria of heat insulating material?
Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.
Q:what materials can make external wall fireproofing paint have the fireproofing effect
Fire retardant coating material is composed of the base material (film forming substance), pigments, ordinary paint additives, fire retardant agent and dispersion medium. Except fire retardant agent, the function of other coating component is same to the commom coating, but the performance and the dosage have special requirements.
