- 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: 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: how is the high-temperature flame-retardant fibre board?
- Temperature refractory fiberboard is of high quality and not likely to be damaged. It is light and easy to install.
- Q: I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry！ I hope you can help me! This time!
- High enough for high temperature resistance. Refractory materials for crucibles shall be subjected to a high temperature greater than 1700 DEG C and the softening temperature shall be greater than 1650 DEG c;
- Q: What are the chemical composition of refractory cement?
- Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
- Q: who knows the fire resistant level of fireproof gypsum board ?
- Gypsum board is flame retardant materials, combustion performance rating B1, but when mounted on a steel joist, it can be seen as rating A(non-combustible material) . So it is fine to use as a ceiling. As for the Dragon brand, rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees. You can randomly choose several samples to run some tests at the quality inspection insititute and the quality of these samples are subject to the testing results.
- Q: What is high alumina refractory?
- It refers to inorganic non-metallic material with refractoriness of higher than 1580℃. Refractoriness refers to the celsius temperature that the cone-shaped refractory sample without load can resist, and under which the sample won't soften and melt down. Refractory material appears together with high temperature technology, and roughly dates from the Middle Bronze age. In the Eastern Han Dynasty (AD25~AD220) of China, fireclay refractories has been used as furnace refractories and saggers for making porcelains. In the early 20th century, refractory material develops toward the direction of high purity, high dense and ultra high temperature products, and meanwhile unshaped refractory and refractory fiber with no need of firing at all and with low energy consumption appear.
- 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.
- Q: What can red stone refractory do?
- In severe cases, the resistance to high temperature without softening down the Celsius temperature. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output. Chinese use less impurity clay in more than 4000 years ago, firing pottery, and have been able to cast bronze. In the Eastern Han Dynasty (AD 25 ~ 220) have been used to make clay refractory kiln firing porcelain material and sagger. At the beginning of twentieth Century, the development of refractories to high purity, high density and ultra high temperature products, while developing completely without firing, small consumption of unshaped refractory materials and high refractory fiber (160 for industrial furnace refractories above 0 DEG C). The former, such as alumina refractory concrete, is often used in large chemical plants, ammonia synthesis plant, two - stage reformer furnace wall, the effect is good. Since 50s, the rapid development of atomic energy and space technology, the development of new energy technology, requires the use of special refractory material of high temperature resistance, corrosion resistance, thermal shock resistance, erosion has excellent properties, such as melting point above 2000 DEG C, oxide refractory compounds and high temperature composite refractory materials.
