Q:Refractory factory grinding brick dust harmful to the body?: Inhalation of this dust can affect people's respiratory tract for a long time

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:Does hardware construction materials contain refractory?: refractory includes one kind of building materials. It is a special material and not commonly used.

Q:What are the refractory materials above 1000℃: It is a piece of cake to meet your requirement, anyway you can try unshaped castables like corundum and other refractory materials used in steelmaking which are above 1500℃ basically .

Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?: You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into

Q:What do refractory materials include?: It is so difficult.

Q:What is shapeless refractory with high performance?: The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.

Q:What is the role of the vermiculite fireproof material?: It can be widely used in construction, decorative ceiling, wall, floor and fireproof door . Especially suitable for airport, railway station, passenger terminal, exhibition hall, hotels, shopping malls, hotels, and other public places and factory, fuel warehouses which have high requirements for fire proofing, etc. With its special thermal insulation, it can also be made to the various types of heat insulation board offered to machines (such as a variety of industrial furnace and assembly line equipment) and furniture, etc. Due to the low density of the product itself, a lot of shipyards in foreign countries use it as ceiling, wall and deck, so the development potential of the domestic shipbuilding market is huge.Expanded vermiculite is porous, lightweight, and dystectic, the most suitable for insulating materials at high temperature (below 1000℃) and fire insulation materials. In the experiment, 15cm- thick cement vermiculite burns for 4-5 hours under 1000℃, but the back temperature is only 40℃. 7 cm-thick vermiculite slate burns for 5mins through the fire flame welding net under 3000℃, the frontage melted, but you don’t feel hot with your hands holding the back side. According to aforementioned, vermiculite slate is superior than all insulating material, such as asbestos, and diatomite products.

Q:Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?: 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.

Q:Who knows what fire heat preservation material are there?: 1 thermal insulation materials with class A combustion performance Rock wool, glass wool, foam glass, ceramic foam, foamed cement, perlite and other 2. thermal insulation materials with B1 combustion performance Specially processed extruded polystyrene board (XPS) / specially processed polyurethane (PU), phenol, powder polystyrene particles. Heat-insulating material with B2 termal insulation performance Fire resistance can be thoroughly sloved by combining molded expanded polystyrene (EPS), extruded polystyrene (XPS) and polyurethane (PU), polyethylene (PE) Hairong module with glass beads (and cooperating with vitrified micro bead inventor Liu Weihua), hope my answer will help!
