Q:What is the interior fireproof thermal insulation material?
The methods of thermal insulation wall have three kinds of materials. First: gypsum board or cement board are stuck outside the polyphenyl board; second: lightweight brick build; third: infill polyphenyl board, lightweight brick is built outside. The first two has almost the same price. The latter is slightly expensive. 60 yuan / square meter is not very expensive!
Q:How long is the fire-resistant time of fireproof wooden door?
fire endurance class A (1.5 hours), class B (1.0 hours), class C (0.5 hours).
Q:what's the varieties of fire-proof sealing material?
Fire blocking material currently on the market include: fire stopping board, foam blocking material, flame resisting module, fire-resisting sealant, flexible organic caulking, WXY-II and fire retardant bag, etc. fire-proof sealing material is widely used in building construction and can ensure high-temperature flame and smoke from fires not spread to another fire compartment, different buildings generally use different sealing methods. Pipeline is generaly sealed by pouring concrete board or mortar.
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 ℃
Q:what is the specs of thermal insulation refractory slab ?
fireproof panel is also called refractory slab, which refers to a layer of veneer. Its thickness is generally about 0.8 mm and there is a veneer made after compression of surface layer of paper, colored paper and multilayer kraft paper. Wear-resistant, heat-resistant and fire-resistant properties, scratch resistant and easy to clean, rich colors and good stability.
Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?
Alkali resistant castables cost the least.
Q:What are the raw materials of refractory? And what are their names?
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:Can someone professionally introduce the classifications of refractories?
It can be divided into two categories of ordinary and special refractory. Ordinary refractories can be devided into acidic, neutral and alkalinee refractories according to chemical properties. Special refractory can be devided into high temperature oxide, refractory compounds and high-temperature composite materials according to the compositions. Furthermore, it canbe devided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and super refractory products (above 2000 ℃) according to the strength of refractoriness. It can be divided into bulks (standard brick, special-shaped brick, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia and boron carbide, etc.) and Indefinite shape (refractory clay, castableand ramming mass, etc.) according to the shapes of products. According to the sintering process, it can be divided into sintered products, cast products, melting jetting products.
Q:What are the requirements when producing fireproof materials by kaolin?
. Kaolin are kaolinite crowded mineral composed of tiny flakes tubulose, lamellar smaller than 2 microns. it is composed of kaolinite, dickite, pearl stone, halloysite etc. I chemical formula of which is AL2O3-2SiO2-2H2O, the main mineral component is kaolinite and halloysite. Except kaolinite and halloysite there are other minerals montmorillonite, illite, pyrophyllite, quartz and feldspar associated. kaolin contains large amounts of the chemical composition AL2O3, SiO2, and a small amount of Fe2O3, TiO2, and small amounts of K2O, Na2O, CaO and MgO, etc. white pottery is made of kaolin and is now internationally accepted scientific name --Kaolin, derived from the eastern suburb of Jingdezhen high-Village side of the mountain kaolinite. kaolin plasticity, cohesiveness, certain dry strength, sinterability and whiteness after burning, making it the main raw material for ceramic production;. white, soft, highly dispersed, adsorption and chemical resistance with other excellent process performance, it has been widely used in the paper industry as well as industrial sectors such as agriculture and defense cutting-edge technology in the field of rubber, plastics, refractories, petroleum refining . according to the purpose and need, it can be processed, treated and purified, they can be used to produce activated clay.
