Q:What types does refractory floor include?
There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
Q:Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
The fire-resistant differences of B1- and B2-level extruded insulation boards are as follow: B1-level materials will be smothered as soon as staying away from fire, namely, they will be extinguished after leaving fire, or be put out in 10 seconds. B2-level materials will be in low-grade combustion, namely, the fire will not get wilder, and drippings will not ignite the filter paper. I hope my answer can help you!
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.
Q:What refractory materials are used in power plant
Vacuum mud machine, sintering furnace! 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:I want to know what is the slim in the refractory bricks
Where are you from, I can introduce to you
Q:Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
1>3>。 When metal heat exchanger is in 700 ℃, it must process high temperature protection, mixed cold wind or cold blast to protect heat exchanger. So this will waste a lot of energy; The comparison of high temperature resistant ceramic heat exchanger using temperature is 1350 ℃ to 1450 ℃; metal heat exchanger using temperature 700 ℃; heat utilization comparison of ceramic heat exchanger can be placed in 1350 ℃ or higher (highest available to 1450 ℃); the oxidation resistance, a very short time will burn out;2 >, waste heat recovery rate is high. Replacing the metal heat exchanger in high temperature and corrosion environment; Comparative ceramic heat exchanger can be used under the condition of 1350 ℃ for a long time. Let's make a comparison, if it is a refractory material industry. <, ceramic heat exchanger is simply won't appear, under the condition of equal to ceramic heat exchanger using, energy saving effect is best, can exchange for the high temperature. <. Ceramic heat can be placed on the nearest of exchanger flue outlet . <, and metal heat exchanger put in place contrast to the ceramic heat exchanger. In the process of using metal heat exchanger, if this situation happens, you can consider the ceramic heat exchanger. Temperature difference is between 650 ℃ to 750 ℃. If the metal heat exchanger is placed in normal place where ceramic heat usually put;The service life comparison: since ceramic heat exchanger with high temperature resistance, this partly replace metal heat exchanger. What's more, energy-saving rate is also different. Metal heat exchanger can be placed in 700 ℃ or less;4 >, corrosion resistance, its application effect is very different. So the metal-heat-exchanger's heat-resistant temperature is high and the service life is the countless times of metal heat exchanger. The place with highest temperature does not need high temperature protection.
Q:Who knows the roofing fireproofing and waterproof material?
Many waterproof materials are suitable for civil engineering, and almost used in the roof waterproof layer, such as: Paint categories: 911 two-component polyurethane waterproof coating single component polyurethane waterproof coating polymer cement-based waterproof coating JS composite waterproof coating and so on. . Coil categories: single-sided waterproof roll double-sided self-adhesive waterproof roll modified asphalt waterproof roll (SBS, APP) polypropylene, polyester, polymer waterproof roll, PVC waterproof roll, EPDM waterproof roll
Q:How long can gypsum board endure fire?
Fire endurance refers to the fire-resistent limit of the whole system of light-gauge steel structure coupled with gypsum. It does nor merely refers to gypsum board. Fire endurance of the common gypsum board with the thickness of 9.5mm keeps 1.5 hours. Those gypsum board with the thickness of 12mm has a fire endurance of 3 hours.
Q:What's the fireproof specification for constrcution external wall thermal insulation materials?
incombustible material: Class A1 (homogenous): such as YT inorganic active insulation material for wall thermal, foam glass, rock(ORE) wool, glass wool, insulation board of aerogel,expanded perlite series, expaned glazed hollow bead, foam insulation boards, ETC. Class A2 (non-homogeneous composite): such as phenolic foam, gelatine powder polyphenyl granule thermal insulation material, inorganic coating materials and other nonflammable material. phenolic foam insulation board, urea resin foam and board, high flame-retardant polyurethane rigid foam and board, high flame retardant polystyrene cystosepiment, gelatine powder polyphenyl granule heat insulating slurry and other combustible materials. Requirements for combustion levels of common antiflaming EPS, common inflaming retarding XPS, common antiflaming rigid PU foam board: Class A is incombustible material (product); B1 nonflammable material (product); B2 combustible material (product); B3 combustible material (product).
Q:Is aluminium oxide refractory material?
Calcination aluminium oxide is refractory material of fine performance made from pure aluminium oxide through high-temperature calcination. It can be made into coarse-grained material, fine-grained material, fine powder and micro powder, which can be made into pure jade burnt products. For example, corundum brick, lightweight corundum bricks. It can also be made into a variety of unburning products together with other materials, such as carbonaceous materials. For example, aluminum carbon and aluminium zirconium carbonaceous materials. As for the production of unshaped refractory material, there are more species. It can be corundum, rubing grain, corundum spinel and can also be added into other materials to improve specific performance. It isn't limited to high-alumina castable refractory and it can be castable refractory, ramming mass, impressionable plastic material, gunning mix and refractory mortar.
