Q:Which refractory quality inspection authority is good?
National testing agencies include National Refractory Inspection Center (i.e. LIRR), China Building Materials Academy (Guanzhuang, Beijing), National Center for Ceramic and Refractory Materials Inspection (Shandong) and China Metallurgical Research Institute (Beijing).
Q:What are fire resistant level standards of class A fire resistant door?
Situations under which fire endurance should at least meet class A fire resistant door standard: In basement, the fire door for room where the stored combustibles average weight exceeds 30kg/㎡; in partition basement, the fire door for partition of room where the stored combustibles average weight exceeds 30kg/㎡; in high building, the fire door for equipment room of automatic fire extinguishing system, fan room and air-conditioner room; in boiler room, transformer cabin, diesel generator room(other dangerous rooms), the fire door in firewall. These places are special and need high security, so they need to meet the standard of class A fire resistant door. What is class A fire resistant door? New Standard for Fire Door GB12955-2008 provides that class A fire resistant door thermal insulation and refractory integrity should be no less than 1.5 hours. In other words, the key of fire door grade is the fire-resistant time. Class A fire resistant door size: class A fire resistant doors have many sizes, and can be customized according to the needs of customers. For example, the size of some fire doors of the diesel generator room is large, while the size of fire doors of basement storing combustibles is small. So the size of class A fire resistant door is also different. Usually Xinduo will take this into account, produce class A fire resistant door with various sizes and can customize according to customer requirements. Class A fire resistant door standard: as is mentioned above, for class A fire resistant door standard, the key is the fire resistant time, no less than 1.5 hours. In texture, class A fire resistant door standard is manifested in the firm joint, uniform distribution of solder joints and smooth surface coating. It has also set fireproof sealing strip which should be straight.
Q:What is streaming fireproof material?
Since streaming fireproof material has less surface energy, so when it is placed in a location to be used, it can be automatically filled so long as mixed with water at proper ratio. And then using vibrator or vibrostand and other tools to compact the mixture so as to satisfy the use requirements. Therefore, it does not require vibration, and it has less friction force between the particles. Generally hydraulic refractory castable must be mixed with water at proper ratio when in construction . While, the concept of "streaming" is in terms of refractory castable.
Q:What are the commonly used fire protection materials
Firewall. The fire wall is made of non combustible material, and is directly installed on the base of the building or the reinforced concrete frame or fire proof walls . Fireproof limit of the firewall, according to the current "building regulations", is 4 hours, wheras the specification of Technical specification for concrete structures of tall building is 3 hours. doors resistant to fire, heat in a certain period of time These door usually prevent the spread of fire and gas in the fire resistant wall, staircase, pipe well. Fire door can be divided into steel fire doors, wood fire doors and composite materials fire door according to the material used. According to the limit of fire resistance can be divided into the class A fire door (1.2h), B fire doors (0.9), class C fire door (0.6h); (3) fire window. Windows resistant to fire, heat in a certain period of time It is usually installed in the fire resistance wall or doors; the fire shutter. This roller shutter can be refractory in a certain period of time. It is typically used for heat and fire insulation in escalator with difficulties to install fire resistant wall, fire resistant valve and smoke resistant valve. Fire resistant valve is installed in the ventilation and air conditioning system of air supply and return air duct, usually in the open state, fire, It will be turn off when the pipeline gas temperature reached 70 degrees, can meet the requirement for fire resistance and insulation for gas and fire. Smoke fire resistant damper installed in the exhaust system pipe, when the pipeline gas temperature reached 280 degrees, it will close automatically, insulating fire and gas.
Q:The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.
Q:What are the use of fire-resistant material and admixture?
I am engaged in admixture and thus familiar. Welcome to exchange!
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:What are the advantages of refractory material?
Jingute WHL type, GDS type
Q:What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
o
Q:What type of firebrick does TZ-3 represent?
Z represents a straight brick, T stands for common brick, common straight standard brick, -3 represents the length, and the specification is 230 * 114 * 65 (mm).
