- Q:Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?
- ShiLiDe materials are rubbish which can not used in many industries now, because the main materials of which are mineral wool boards. These boards are harmful to human body, will lead to chronic poisoning, and the quality of which is bad! You must pay attention to it! They can not be used in chemical and pharmaceutical plants.
- Q:What are the standards of refractory concrete ?
- Refractory concrete is generally divided into three categories: Light insulating concrete (for insulation); medium-quality refractory concrete (It is used for the parts where requirement of refractory temperature is not very high, and it can withstand a certain erosion of air); heavy refractory concrete (It is used for the parts where requirement of refractory temperature is fairly high, and it can withstand a certain intensity of erosion of air). It mainly depends on the design temperature and the using parts. There are a variety of raw materials, of which aluminum oxide is one of the most commonly used materials, others are alumina hollow ball, magnesium oxide, zircon, etc. It depends on the design temperature and the parts on use. Commercial concrete station generally can not produce it, instead it is compound by professional refractory concrete factories.
- Q:Who knows the external wall thermal insulation materials fire rating requirements?
- The basic requirements of ratings. The design should comply with relevant state regulations and standards, the combustion performance used in exterior insulation material shouls be level A and not less than the level B2 fireproofing material. The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
- 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 the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
- You'd better oxidize magnesia preformed unit at room temperature for a longer period of time, then bake it, during which, it's enough to control the maximum temperature within 300 degrees. During the middle process, usually heating up for 4 hours and keep warm for 3 hours. The entire heating up process takes about 20 hours. If it is the site operation magnesia-based castable, it should be heated slowly in the early stage, and pay attention to keeping warm at 80 degrees Celsius. Every manufacturers has their own heating curves, so do not blindly adopt existing curves, try to make your own heating curve.
- Q:What are the advantages of refractory material?
- Jingute WHL type, GDS type
- Q:What are the main components of refractory cement?
- SiO powder is often used. Ultra-fine powder refers to less than 1 / zm particles which are made by hydrolysis of ethyl silicate or made from recycled dust in the smelting process of ferro-silicon alloy. Non-cement castable refractory are castable refractory material which contains no cement instead it relies on the coagulation and combination by adding ultra-fine powder or sol (see refractory castable), and it is an amorphous material with high activity. Silica sol is made through Ion-exchange of sodium silicate after Na ions are removed. The easiest method is to prepare by reaction of aluminum metal with hydrochloric acid or alchlor. It is a thermodynamically unstable system which has certain requirements for ultra-fine powder and sol. It is different from non-cement refractory castable, Cr2zrOz and etc. It has low impurity content, and can bond with itself, so it has good binding strength. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. Such recycled SiO2 powder has an average particle diameter of 0.5 pm, therefore when adding the gelling agent (electrolyte), it can coagulate and give the products some bonding strength. Non-cement castable refractory is made up of refractory aggregate and powder and it is round. Since the use of superfine powder or sol as binder. The size of sol particles are of 0.1 ~ 1 m. Non-cement refractory castable takes oxide or synthetic compound ultra-fine powder or oxide sol-gel which is similar to the chemical composition of material in tungsten castable. There are several ways to prepare alumina sol. The sol used are mainly alumina oxide and silica sol. The surface area is large, and it helps to improve high-temperature structural strength. Non-cement castable refractories rely on oxide ultra-fine powder or sol to coagulate and combinate. It is a refractory castable (also known as chemical bonding castable) which uses chemical binder instead of cement for combination.
- Q:How to divide the fire resistant level of EVB?
- 1. The thermal insulation material of level A combustion performance: Inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope I can help you!
- Q:which is better as household fireproof material ?
- If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.
