- Q: What are the materials of insulation firebricks?
- The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.
- Q: Does anyone know the difference between refractory and thermal insulation material?
- The main difference between insulation bricks and refractory bricks are as follows: 1. Insulation effect The heat conductivity cofficient of insulation bricks is usually 0.2-0.4 (average temperature of 350 ± 25 ℃) w / mk while the heat conductivity coefficient of refractory bricks is 1.0 (average temperature of 350 ± 25 ℃) w / mk or more. Thus it can be seen that the insulation effect of insulation bricks is much better than that of refractory bricks. 2. Refractoriness The refractoriness of insulation bricks is generally below 1,400 degrees centigrade while the refractoriness of refractory bricks is above 1,400 degrees centigrade. 3. Density Insulation bricks are generally light-weight insulation material, and the density is generally 0.8-1.0g / cm3. But the density of refractory bricks is above 2.0g / cm3.
- Q: What are the requirements of refractory temperature of refractory brick?
- Refractory brick, called refractory?brick for short, is refractory material made by firing refractory clay or other refractory raw materials. Faint?yellow or brownish, it is mainly used in building smelting furnace. It can resist 1,580 ℃ -1,770 ℃ high temperature.
- Q: I want to consult the fire resistant level standards of external wall thermal insulation materials.
- 1, The thermal insulation material that has level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2, The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3, Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See article 4.3.6 in the 2009 edition construction technical measures. Level A insulation material is just for fire protection, so its thermal insulation performance is worse than the organic XPS or EPS materials. Hope this will help you.
- Q: How to do environmental impact assessment for refractory Co., Ltd.
- 1, first of all, the EIA unit and the construction party signed the EIA contract. The contract is only legally valid. Generally speaking, the contract will indicate that the first payment has been received before the work begins.2. Collecting information. This is a very important link in the EIA, which is directly related to the quality of the eia. There is a great variety of data,Generally, the construction party will write a list of environmental impact assessment information.
- Q: what are the requirements of fireproofing material?
- answer: 1 fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc. 2, fireproof?panel is the most common texture in the market. There are two common types: One is the high pressure decorating refractory slab, it's advantages are fireproofing,moisture-proof, wear-resistant, oil resistant, easy to clean, and it has various colors; another one is glass magnesium fireproof board, external layer is decoration materials, and inner layer is mineral magnesium fireproofing material, and it can endure 1500 degrees high temperature but has bad decoration. Installing fireproof suspended?ceiling in outlet channel of construction, stairwell and corridor can ensure safe evacuation of people and protect people from attacking of fire spreading in the disaster. 3, the production process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.
- Q: Ask some questions about refractories
- The main chemical composition of Al2O3 = 75%, Al2O3 = 89%Bulk density g/M3 2.9 3.15Reheating linear change rate 1450 C -0.10 +0.01Apparent porosity% 1917Compressive strength MPa 2228Flexural strength MPa 810Refractoriness 21002150 DEG C
- Q: Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?
- Advertising materials can be divided into fireproofing and non-fireproofing ones which can not tell the differences with naked eyes. You can ask 3M to provide test reports or go to a the third party test organization SGS to do flame retardant test, maybe I can help you. Mineral wool board is harmful to human body, will lead to chronic poisoning, the quality of it is bad! You must pay attention to it! It can not be used in chemical and pharmaceutical plants.
- Q: Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
- There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
