Q:Who knows the classifications of magnesia refractory?
They can be devided into two major categories of fettling magnesite grain and magnesite products. They can be divided into fettling magnesite grain, magnesia?brick, magnesia-silica brick, magnesia-alumina brick, magnesium-calcium brick, magnesia-carbon brick and other varieties according to the chemical compositions and purposes Its performance is greatly affected by CaO / SiO2 ratio and impurities. The load softening point and thermal shock resistance of high purity magnesia brick are much higher than those of the general magnesia bricks. It has high refractoriness and good resistance for alkaline slag and iron slag, which is an important kind of advanced refractory material. Magnesia products are mainly produced by sintering, and sintering temperature is generally between 1500 ~ 1800 ℃. Besides, chemical binder can be added to make unburned?bricks and unshaped refractories. Mainly used in open hearth furnace, electric furnace, oxidation converter, non-ferrous metal metallurgy furnace, cement kiln and calcining kiln for basic refractory.
Q:How to detect the acid resistance of refractory? Is there any standard? Thank you
Setting the acid resistancere of fractory products is simple; R22, two measurement methods are both bricking refractory products, using the mass fraction of the original dry to indicate. It is generally select vitriol as the medium of erosion, such as the international standard determination of the resistance to sulfate of dense shaped refractory products "(ISO8890) and PRE /, grinding fine particles to 0.63 ~ 0.80 mm, and then measure its quality loss, put it in the vitriol with mass fraction of 70%, finally boil 6 h.
Q:What are the grades of refractory exterior wall thermal insulation materials?
Classification of fire rating of extrior thermal insulation materials 1, According to national standard GB8624-97, the combustion performance of building materials are divided into the following grades A level: Incombustible building materials: Materials hardly burn. B1 class: Flame-retardant building materials: Flame-retardant material has good flame resistance. In case of fire in the air or at high temperature, it is difficult to catch fire and the fire will not spread quickly. And when the combustion source is removed, the burning will stop immediately. B2 Class: Combustible building materials: Combustible materials have a certain flame retardancy. In case of fire in the air or at high temperature, it will immediately burst into flames and it is easily to spread fire, such as wooden column, wooden roof truss, wooden beams and wooden stairs, etc. B3 level: Inflammable building materials: It has no flame retardant effect, and it is extremely inflammable, and the risk of fire is high. Classification of exterior wall thermal insulation materials according to fire rating: 1. Thermal insulation materials with A-level combustion performance Rock wool, glass wool, foam glass, foamed ceramic, foam cement, hole-closed perlite, etc. 2, Thermal insulation materials with B1-level combustion performance: Extruded polystyrene board (XPS) after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polystyrene granule, and etc. 3. Thermal insulation materials with B2-level combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:Which brand of thermal insulating refractory is good?
The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Refractories are non-metallic materials with good resistance against thermal shock and chemical erosion, low heat conductivity coefficient and expansion coefficient. It requires high temperature resistance in nature. It is difficult to transport suc materials in silicious thermal insulation board production base. Silicious thermal insulation board is a kind of thermal insulation material during casting process. Raw materials are non-porous refractory?aggregate, porous refractory?aggregate, organic fiber and inorganic fiber.
Q:What's the frequently used refractory material?
What's the frequently used refractory material in the market? It is usually classified into four categories: Common Refractory: silica?brick, semi-silica brick, refractory fireclay block, high alumina refractory brick, magnesia brick, etc. Unshaped Refractory: repairing?mass, ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, sling refractory, refractory coating, lightweight refractory?castables, stemming, etc. Special Refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nonoxide refractories like nitride, silicide, sulfide, boride and carbide, and oxide refractories like calcium oxide, chromium hemitrioxide, alumina, magnesium oxide and beryllia, etc. Fireclay Insulating Refractory: diatomite product, asbestos product, insulation?board, etc.
Q:What's the A grade fireproofing material?
Main materials are steel, wood, steel and wood. Fire door is one of the measures for buildings fire separation, and it is generally installed at the firewalls, entrances and exits of stairwells or tube well openings, which is required to play the role of fire protection and smoke control. Fire door plays an important role in preventing the spread of smoke and fire and reducing damages, so it must be strictly required. Fire dooor is classified into three classes of A, B, C, and their fire insulation and fire integrity is greater than or equal to the following values: A class fire door: 1.5h; B class fire door: 1.0h; C class fire door: 0.5h. It is in accordance with the provisions of 4.5.1.2 Article in GB12955-2008 "New Standard of Fire Doors".
Q:Fire resistance and evaluation of refractory for casting
The products to be tested are broken and ground, adding organic binders (usually dextrin) that do not affect the refractoriness. Water is used to make standard sized test cones, as shown in figure 1-2-1. Test cone is positive, three edge cone, the bottom side length of 8.5mm, the top side length is 2mm.Test, the equivalent of high standard cone refractoriness of the 2 products to be high, No. 1 and No. 1 high temperature low standard cone of each one, and the 2 to be tested in accordance with regulations frustum cone plug made of high aluminum material, a cone prism and vertical 8 degrees. 1 degrees tilt angle. Then, the cone is heated in a high temperature furnace. When the test cone with a high temperature and bending down to the standard cone top contact cone, the high standard cone refractoriness refractoriness is running.
Q:Which fireproofing materials factory is the best in Xiangyang?
Of course, it is "Lvchuang Construction Energy Saving Engineering Co., Ltd." in Xuzhou, which main products are A-level fireproofing thermal insulation boards. It has many projects. B1-level fireproof materials are polyphenyl boards, extruded sheets, phenolic foam boards, Polyurethane board, sea capacity building energy efficiency module. Flame retardant has been added to the sea capacity building energy efficiency modules which has a B1-level fireproofing performance. You can also add expanded glazed hollow beads to them if you are worried about the security.
Q:Which are fire proofing thermal insulation materials?
Which are fire proofing thermal insulation materials? Which fire proofing thermal insulation materials are commonly seen?
Q:Can the teflon material resist fire?
Teflon material does not burn, but the heat resistance temperature of it is about 300℃.
