- Q: what's the seal of fireproofing material?
- Folded organic putty takes organic material as bond,it has certain flexibility or plasticity while using, and it's products are thick liquid or cement shaped object. Folded WXY-II is powered?solid that takes inorganic materials as main components, it has certain workability while used with admixture. Folded fire retardant bag is the packaged object made by fireproofing material, and it's suitable for fireproofing seal of larger openings or fire separation of cable?bridge(fire retardant bag also refers to fireproof bag) Folded fire retardant module is the solid made by fireproofing material with certain shape and size, and it is easy for cutting and drilling, suitable for fireproofing seal of opening and cable?bridge. Folded seal board is made by fireproofing material, it's easy for cutting and drilling, suitable for fireproofing seal of large opening. Folded foam seal is a kind of fireproofing material that can automatically expand and foam and sealed by opening after injecting the foam into opening. Folded sealing strip is a product or flexibility coiled material mede by fireproofing material with certain geometry shape. Folded sealing gum is a kind of liquid fireproofing material that has a function of fireproofing and sealing. Folded fire retardant bag is soft and windable tape-shaped product made by fireproofing material, it is winded on the external surface of plastic pipe and fixed with steel belt or other proper methods, it's the expansion, squeezing and softening pipe after contacting with fire, opening left by burning or soften of seal plastic pipe. Folded fire retardant ring is the product made by fireproofing material and metal shell, it's covered on the external surface of the plastic pipe, expanding and sealing after contacing with open fire, the opening left by burning and soften of plastic pipe when it passes through the opening of wall and floor.
- Q: Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports
- Porosity, volume density, water absorption, true density, thermal expansion, thermal conductivity and heat capacity.
- Q: Are fire materials poisonous after burning?
- High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
- Q: What is unshaped refractory?
- Concrete。 Early concrete technology appears, it is not forming products in the heat furnace, some parts such as pit heating furnace furnace wall, rotary kiln mouth ring, cutting slope and discharge chamber wall, etc., are able to design large masonry (top heating block weighing 3-4 tons) made concrete. Concrete cattle production method is to pour the material into the model, vibration molding, after the release of heat treatment, to provide users in addition to large blocks, weight, in use, and machine pressure brick no essential difference. The amount of water used in the casting material produced by the manufacturer is less than 10% above that in the field, and the processing quality is good and the quality is stable. As the bricks are large and heavy, the site shall have lifting equipment. As long as the site can be hoisted, the concrete shall be used as far as possible, or smaller ones, and some people can lift it. Concrete does not require the user to do a special heat treatment, this point is very meaningful.
- Q: Which industry does refractory belong to? Does it belong to construction industry?
- I do not recognize all the answers. No matter what kind of refractory can be used in construction. Biulding syove or kiln is construction. So personally, it belongs to construction indusrty.
- Q: Using what kind of melting aluminium furnace refractories is more appropriate?
- If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
- 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: What is the acceptance standard of refractory?
- It depends on the variety of materials. In general the main test items include chemical composition, refractoriness, refractoriness under load, creep, volume density, linear change, strength, slag resistance, thermal conductivity and thermal expansion. If it is shaped products, it is required to inspect the size deviation and whether it has edge. Detection method accords with the relevant national standards and there are lots of them. You can refer to the standard compilation.
- Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
- The combustion performance of materials could be divided into: A( noninflammability), B1(flame retardancy), B2(flammability), B3(inflammability). Building materials are divided into four ranks according to these properties. 1. In accordance with Code for Design of Building Fire Protection(GBJ16-1987)(revised edition in 2001), fire hazards in producing and storage can be divided into five types. In Fire Prevention Code of Petrol Chemical Enterprise Design(GB50160--1992)(revised edition in 1999), classification of fire hazards is also achieved according to the hazards of materials that have been using, producing and storing. Measures in prevention of fire explosion could be taken from the perspectives of fire separation, fire resistance level of structures, allowable floors, safe evacuation, and fire extinguishing facilities based on different levels of fire hazards. 2. Four fire resistance rating of buildings are listed in the book Code for Design of Building Fire Protection. And specific stipulations are made to the fire resistance of main elements of buildings, such as bearing walls, beams,pillars, and floors. When designing a building, if permitted, refractory materials of high-rank should be adopted in those buildings which have high potential fire hazard and a lot of combustible material and valuable equipment. While making sure fire resistance rating, the duration of fire resistance of each elements should meet its requirements.
- Q: How do refractory materials apply into pyrophyllite?
- Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
