Q:What are fireproofing materials?
1. With the tape made by double-coated flame-retardant and chemical defense surface adhesive and that only occurs charring with no melting drops and maintains good strength when meeting with fire as main material, and by the laminating-sewing-pasting process, clothing body and gloves are made and equipped with flame retardant, chemical defence, voltage resistant, and puncture resistant boots, the clothing assembly is constituted. 2. They are usually asbestos. Some of them have better quality and are made by wiredrawing of aluminum zirconium and silicon mixtures, and of course others are directly manufactured with some natural objects. 3. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. Coatings are usually those with fine powder, high density and good sealing. 4. Phenolic foam board can meet the requirement and its test temperature can reach up to 2000℃ under which it has no molten droplet but good integrality. Thermal Conductivity: 0.03W/(mk). It is non-flammable, non-toxic and smokeless! 5. The hollow ceramic micro-bead is good in thermal insulation and fire-retardance.
Q:What are fire?ratings of wall thermal insulation material?
1.thermal insulation material with grade A combustion performance: YT inorganic active insulation material for wall thermal,rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2.thermal insulation material with grade B combustion performance: Extruded polystyrene board(XPS)after special treatment/polyurethane(PU) after special treatment, phenolic aldehyde,gelatine powder polyphenyl granule, etc. 3.thermal insulation material with grade B2 combustion performance: Molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.
Q:What is the common inorganic fireproof and thermal inuslation matertial?
inorganic materials of insulation materials 1, inorganic thermal insulation materials are mainly concentrated in the materials that have a certain insulation effect and can achieve level A fireproofing, such as aerogel blanket, glass wool, rock wool, expanded perlite and micro-nano thermal baffle. 2, rock wool production is harmful to human body, workers also do not want to occure the situation under the construction. The cycle of rock wool construction plate is long about 2 years from construction to production. The supply of the domestic wool market also cannot meet the requirements for use. 3, expanded perlite has great weight and high water absorption. 4, the insulation performance of micro-nano insulation panels is 3-5 times that of conventional insulation materials, commonly used in high temperature environment, but is more expensive. 5, aerogel blanket is level A1 inorganic fireproofing building materials, thermal conductivity at room temperature is 0.018W / (K · m), and absolutely waterproofing, its insulation performance is 3-8 times of traditional materials, which can replace the unenvironment-friendly froconventional flexible material with poor insulation properties, such as glass fiber products, asbestos insulation felt and silicate products.
Q:How many kinds of refractory materials are there in the EI?
I suggest that you contribute articles to foreign SCI journals for the odds are better, and generally the articles that fill the bill will not be rejected. The traditional refractory materials can contribute to EI journal. If being rejected by EI journal, you can also contribute to Russia's journal Industrial Ceramics and Refractories. I didn't contribute to the Journal of Wuhan University of Science and Technology, the receiving cycle is almost 3 to 4 months. Though the impact factor is low, domestic EI journal is not so good, it is still SCI journal. This is my own experience, please take my advice. The best journals are the Journal of the American Ceramic Society and the Journal of the European Ceramic Society, I heard that they are not bad. But the best domestic EI refractory material journal is the Journal of The Chinese Ceramic Society. It is very long, but if it belongs to your university, it is another pair of shoes. Journals now all want to have materials about functional ceramics, and they don't want Chinese articles, if your English is not well enough, you can choose Ceramics International and Japan Ceramics but they have strict manuscripts reviewing standards.
Q:which kind of material is chosen for fireproofing window?
Firstly, fireproofing window glass must be tempered, ordinary glass won't play a role of fireproofing, and fireproofing window fan is fixed, can't be open, if you can open it, it won't play a role of fireproofing. And you can ask the property to provide texture report of fireproofing windows, fireproof material stipulated by our national fire protection laws and regulations must have fireproofing inspection reports, there must be. and fire window glass should have a fireproofing sign. The main role of fireproofing window is to isolate the fire, and play a role of fireproofing and escaping, avoid the fire quickly spread in.
Q:What is streaming fireproof material?
Streaming fireproof material is castable refractory that can flow and degas without virbration, which is suitable for thin-wall or places that cannot be molded by vibration because of complex shapes. Well, appropriate amount of water is necessary for it. Its characteristic goes that it can be cast into various shapes of construction body without virbration and it will not reduce or not significantly reduce the performance of castable at the same time.

Silmo brick, alumina-magnesia brick; 2. coke oven, aluminum silicate... 8 categories)& nbsp, teeming ladle, glass furnace ...... 7 categories) high alumina refractory products (blast furnace, electric furnace, cement kiln, magnesia, glass furnace; 3. high alumina refractory mortar (high alumina, glass kiln ...... 6 categories) special refractory products (magnesia-carbon bricks, aluminum-carbon bricks, MgO-C, shapeless refractory products& nbsp, light weight, sliding plate bricks, cement kilns: There are 26 categories in refractory products, clay, calcium silicate, ceramsite lightweight... 10 categories) & nbsp, air heating furnace, sheets; 1 refractory castable (alumina-magnesia, blocks, resistance furnace... 11 categories) alkaline refractory products (magnesia. First, thermal insulation refractory products (ceramic fiber; clay, diatomaceous earth, steel fibre reinforcement...14 categories) & nbsp, silicon carbide brick ...... 19 categories) Second, China is the largest refractory production country in the world, clay, non-water cannons mud, converter, siliceous, teeming ladle, profiled) siliceous refractory products (coke oven, dense shaped refractory products (all kinds of bricks, electric furnace roof, glass kiln ...... 5 categories) clay refractory products (blast furnace, high alumina ...... 4 categories) three
Q:How to apply the alumina powder on refractories?
The most common one in use is the refractory bricks.
Q:what's the application of fireproofing abs materials?
ABS alloy shell, a toy of child, low load bearing, refrigerator lining, it can be processed into various wear-resisting sheets, plates,and has good electrical performance, it can be used as electronic components or auto parts, all kinds of insulation materials, it's easy to machining on the surface, so it can be made into designated special products (such as electroplate), and easy coloring,
Q:What are the requirements of refractory temperature of refractory brick?
Oxygen fluctuation of load once happened during operation. Sometimes oxygen control valve will cause oxygen fluctuation of load, and sometimes large particles will block valve of high pressure coal slurry pump. The sudden drop in flow of coal slurry may cause relative excess of oxygen. Oxygen fluctuations directly cause fluctuations in furnace temperature. The range of oxygen fluctuations is 500m?-600m?. The maximum can reach about 1000m?. A sudden increase in oxygen causes a sudden increase in furnace temperature, which will suddenly burn out high-temperature thermocouple. The situation has a great influence on refractory brick and should be avoided. Furnace temperature is very inportant to life of lining of refractory bricks, so it should be strictly controlled not to overheat. There is a cinder layer on the surface of refractory bricks under the condition of normal production. In fact, cinder layer is dynamic. If the temperature is low, cinder layer is thick. If the temperature is high, cinder layer is thin. Appropriate cinder layer may slow the scour of high temperature gas and molten slag. The requirement of refractory brick is higher than that of stoves which use heavy oil as raw material. The main reason is permeability and corrosion of molten slag to refractory material. When replacing refractory bricks, it is found that penetration thickness is 10mm-20mm. After slag penetrates, strength decreases significantly. If temperature is high, erosion intensifies. According to the relevant information, when the operating temperature exceeds 1400 ℃, etching effect multiplies.
