- Q: I want to consult the fire resistant level standards of external wall thermal insulation materials.
- Fire resistant level standards of external wall thermal insulation materials: 1, The thermal insulation material that has A-class 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 B1 level 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), polyethylene (PE), etc.
- Q: How long is the duration of fire resistance of hollow glass magnesium board
- It belongs to second level refractory building. The fire resistance limit of prestressed hollow slab is 0.7 hours, according to provision 3.2.7 and 5.1.5 of fire safety rules. When reaching 20 thick protective layer, the fire resistance limit of the prestressed hollow slab is 0.7 hours. When reaching 30 thick protective layer, the limit of the fire resistance of prestressed hollow plate is 0.85 hours. Protection layer of prestressed hollow board prefabrication is 15, plaster ceiling has 12 protection layers, the total protection layer amounts 27, which can achieve fire resistance limit of not less than 0.75 hour.
- Q: What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
- Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
- Q: What a blast furnace refractories generally?
- Usually metal anchorage plus wear-resistant refractory spray paint. at the middle part we use high alumina bricks, corundum bricks. high duty refractory is important in improving bosh furnace lining.
- Q: Who knows about the fire endurance of sintered shaly hollow bricks?
- 1. after roasting at high temperature of more than 1200 degrees, shale burned bricks in construction works can be free from expanding with heat and contracting with cold. 2. masonry walls can be plastered with no needs of any anti-cracking, reinforcement measures, and walls will not bulge and crack, which can reduce the construction cost, as well as are preferred building materials of frame structural engineering. 3.They have good sound insulation and thermal insulation performances, are one of the green building materials that the state currently promotes. 4. They have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance.
- Q: How long is the fire endurance of the rock wool board?
- The rock wool board takes the basalt as raw material and is processed into artificial inorganic fiber through high temperature melting, which is light in weight, non-combustible, heat absorptive, small in thermal conductivity. The initial development in construction is a common type of application used for industrial buildings, which should be consistent with the requirements of "building insulation application categories and basic requirements" . In June 1981 the pre-launch succeeds. The rock wool board is a new type of insulation, burning compartment and sound-absorbing material. Generally the fire resistance of the rock wool board is 140-180 degree within two hours, It is best not to exceed this safe period, in order to avoid security risks.
- Q: Which one is the best refractory material?
- 1, Acid refractory usually refers to the refractory material whose content of SiO2 is more than 93% , and is characterized by erosion resistance to acid slag under high temperature , but it is easy to react with alkaline slag. Commonly used acid refractory materials include silica bricks and clay bricks. 2, Alkaline refractory material is a kind of refractory material whose components are magnesium Oxide or the mixture of magnesium oxide and calcium oxide. 3, Aluminosilicate refractory refractory material refers to refractory material which makes SiO2-Al2O3 as the main component. According to the content of Al2O3, it can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%). 4, Fusion-cast refractory material refers to a kind of refractory product that melt the batch through some certain methods refractory products, and then pouring into a certain shape. 5, Neutral refractory materials mean that under high temperature, don’t react with acidic or alkaline slag. 6, Special refractory material is a new type of inorganic nonmetal material, which is developed on the basis of traditional ceramic and refractory materials. 7, The amorphous refractory material is a mixture of refractory aggregate and powder, binder or admixture, which can be used directly or after adding the appropriate liquid mixing.
- Q: Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
- According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire?compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance includes unexposed surface temperature rise, its fire endurance should not be less than 3 hours. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.
- Q: Who knows the fire endurance of rock wool color plate?
- Colored steel rock wool board is used for areas with high fireproofing requirements. Colored steel rock wool board belongs to class A according to "Fireproof? Specification of Building Interior Decoration?Design" whose lifetime can reach more than 15 years, operating temperature can up to about 700 ℃, maximum fireproofing time is 6 hours. And rock wool colored plate is environmentally friendly materials, which is is the preferred material in the construction industry .
- Q: Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
- Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material.
