Q:Who knows the external wall thermal insulation materials fire rating requirements?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the unit price is very expensive. Insulation materials in the domestic market have some disadvantages, it is better to considere the materials within the acceptable range in the building needs.
Q:What refractories can withstand high temperature above 2100 degrees?
It depends on refractoriness of refractory materials. The three refractory bricks above is 300 degrees higher than quartz sand in refractoriness. Magnesia brick: Cast corundum brick with greater than 2000 degrees refractoriness should be enough for you to use. But products like quartz sand merely keeps 1600 to 1700 in refractoriness generally. As you described that refractoriness is greater than 1990 degrees, it is feasible to use hearth made by mixing of quartz sand and refractory cement, which can work for some time at 200 degrees. It is also ok to use dolomite brick whose refractoriness is greater than 2000 degrees.
Q:What refractory materials are used in power plant
And then I will introduce some application of thermal material in power plant (below) I hope I can help you. Energy saving is the trend of future industrial development efforts, grinding machine, conveyor belt, so the production of light thermal insulation materials will gain state support, drying kiln. Our factory mainly produce light thermal insulation brick. The refractory material we use most is light insulation brick, and the equipment used is sand mixer (Luohe, Henan)
Q:Which are fire proofing thermal insulation materials?
aluminum silicate fiber, ceramic fiber, etc,
Q:Does refractory belong to metallurgical auxiliary materials?
Refractory is widely used in industrial circle, such as metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate and power, and its coonsumption is the maximum in metallurgy, accounting for 50% to 60% in total output. In order to improve slag-corrosion resistance of furnace lining, usually choose carbon-containing refractory. Refractory of various furnace lining are respectively: For the body, it is clay brick; as for the lower part, bosh and middle, it is SiC brick; for furnace bottom, it is carbon brick. Lattice brick is an important refractory product used in air heating furnace and regenerative chamber. Refractory is widely used in metallurgy. In order to improve slag-corrosion resistance of lining. Central line in tuyere and hearth are high-alumina brick. Refractory consumption is the maximum in metallurgy, accounting for 50% to 60% in total output. For the bosh and middle, it is SiC brick. In order to improve its thermal storage capacity: The furnace stack is clay brick. It is defined as refractory where the physical and chemical properties allows its use in high temperature environments; The lower furnace body
Q:What are the applications of refractory busway?
Fire-resisting busway can be applied to power transmission and distribution systems with rated voltage below 690V, rated current is 250-5000A and frequency is 50-60Hz. After years of testing and industrial electrical operation, its electrical resistance, fire resistance, metal structural property have reached the advanced level in China.
Q:How about the prospect of refractory material?
is developing well. Many plants are required t o use fireproofing materials.
Q:What's the fire endurance of fire windows?
That is fire resistance rating, fire-resistant time in the case of fire! It can be basically classified into the following levels and the fire endurance of the fire window is as follows as well: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. This is in accordance with the latest specification of gb16809-2008 fire windows.
Q:What is the type of heat resistance property of high temperature electric furnace ?
According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
