- Q: Who knows about the fire endurance of A grade fireproofing glass doors?
- The fire endurance of grade A fire resistance rolling shutter doors should be no less than three hours. Fire doors can be divided into A, B and C grades according to their fire endurance which should be no less than 1.20 h, 0.90 h and 0.60h respectively. Places where are difficult to set fire-proof bulkheads can use fire resisting shutters as partitions of fire?compartments. The fire endurance of fire resisting shutters that include unexposed surface temperature rise as judging condition should be no less than 3 h. Fire resisting shutters that exclude unexposed surface temperature rise as judging condition should set up independent protection of closed automatic water spray system on both sides of shutters, and the duration of water spray system should be no less than 3.0 h.
- Q: Which kind of refractory floor is easy to use? ?
- Recommend: Yong Wei fireproof board Henan Yong Wei Anfang Co., Ltd., located in Qinbei industrial agglomeration area, Qinyang City, Henan Province, was founded in 1995. It strated from the initial one fire decorative plate production line. After years of development, it has become the biggest fireproof decorative board production base with 25 fireproof board production lines.
- Q: Ask some questions about refractories
- Application: it is suitable for blast furnace tapping system.
- Q: What is refractory aggregate?
- It includes two categories: coarse aggregate and fine aggregate.
- Q: How to choose construction external wall thermal insulation and fireproofing materials?
- The width of fireproof partition shuld be greater than 30CM, and the thickness should be the same as total thickness of thermal insulation materials. Fire barrier zone thermal insulation board and base wall should be stuck in whole area. Fire Barrier zone thermal insulation board should be stuck with the assistance of anchor bolt which must press the mesh of the bottom layer. Fire Barrier zone should be set above the door and window, with a distance of less than 50cm between the lower edge of fire barrier zone and the upper edge of window.
- Q: what is the material of fixed first rate fire resistant window?
- Window frames and fireproofing glass, fire sealing strip, fireproofing glass mound layer, which is infexible fan, and the flexible fans have to plus folding and closing window cleaner. (3) window frames must be integral with the building, using wood or iron to connect the wall. After the installation of the steel frame, the cement mortar must be watered between the window frame and the wall, and it should conserve more than 24 hours before normal use.
- 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's the A grade fireproofing material?
- A grade fireproofing material: 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire?retardant?coating; 9. fire-proof?sealing?material.
- Q: What are the uses of refractory materials of glass furnace?
- What are the uses of refractory materials of glass furnace? The refractory materials of glass furnace have a good corrosion resistance to steel slag, but are poor in thermal shock resistance, and the deformation temperature of loading at high temperature is low. Magnesite chrome bricks which are made of chrome ore and magnesia In different proportions have a good thermal shock resistance. They are mainly used as crown bricks of basic open-hearth furnace. The refractory materials of glass furnace are mainly applied to open-hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting as well as some high-temperature thermal equipments, and they can be used for reaction tanks and liners of autoclave.
