- Q:Could you tell me the fire-resisting time of class B fire proof door?
- Could you tell me the fire-resisting time of class B fire proof door?
- Q:Can anyone tell me what is A-leve fireproof material?
- Combustion performance of materials can be divided into: A-level, B1-level, B2-level and B3-level, which respectively refer to noncombustible, difficult-flammble, flammable and inflammable materials. Building materials can be divided into four grades based on combustion performance (noninflammability, flame retardancy, flammability and inflammability). According to the stipulation of "Specification of Fireproof Design for Buildings" (GBJ16-1987) (2001 revised edition), fire hazard of production or storage should be divided into A-level, B-level, C-level, D-level and E-level. In "Specifications on Fireproof Design for Petrochemical Enterprises" (GB50160--1992) (1999 Revision), it also stipulates that fire hazard should be classified on the same basis of subtsance danger in usage, production or storage. According to different fire hazard, requirements and measures of oreventing and restricting fire explosion can be put forward from the aspects of fire?separation distance, fire resistant rating of buildings, allowed floors, safe evacuation, fire fighting facilities and other aspects.
- Q:Does refractory belong to metallurgical auxiliary materials?
- Refractory is widely used in industrial circle, such as metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate and power, and its coonsumption is the maximum in metallurgy, accounting for 50% to 60% in total output. In order to improve slag-corrosion resistance of furnace lining, usually choose carbon-containing refractory. Refractory of various furnace lining are respectively: For the body, it is clay brick; as for the lower part, bosh and middle, it is SiC brick; for furnace bottom, it is carbon brick. Lattice brick is an important refractory product used in air heating furnace and regenerative chamber. Refractory is widely used in metallurgy. In order to improve slag-corrosion resistance of lining. Central line in tuyere and hearth are high-alumina brick. Refractory consumption is the maximum in metallurgy, accounting for 50% to 60% in total output. For the bosh and middle, it is SiC brick. In order to improve its thermal storage capacity: The furnace stack is clay brick. It is defined as refractory where the physical and chemical properties allows its use in high temperature environments; The lower furnace body
- Q:What is the best refractory company?
- Palladium activity is very rich ah, Sina micro-blog introduced a lot of jewelry related content, style is very unique, see people could not help but want to store to buy impulse.
- Q:The performance of refractory material
- As for easticity modulus, you can serach for information on the Internet or specialized books.
- Q:What are the raw materials of refractory?
- Of course, different types have different raw materials: Magnesite (the electric?smelting: alkaline refractory, magnesia-carbon bricks, alkaline, high-purity) + crystalline flake graphite + phenolic resin + additive (silicon powder, aluminite powder, silicon carbide powder, or high-temperature asphalt,etc.) , acidic refractory: The neutral is not easy to answer. such as. You can check out the classification, such as
- Q:Does anyone know about the A-level fireproof materials?
- A-level decorative integrated plates of thermal insulation, water- and fire-proofing mainly can prevent fire and insulate heat with A-level fireproofing glass fiber as thermal insulation materials. The classification of A1-level external wall materials of thermal insulation, fire- and water-proofing: First, external wall thermal insulation materials: 1. silicate?thermal?insulation?materials 2. gelatine powder polyphenyl granules 3. steel wire gauze picking cement cystosepiment (grs board) 4. extruded sheets; Second, roofing materials: 1. xps extruded sheet 2. EPS foam board 3. perlite and perlite brick 4, vermiculite and vermiculite bricks; Third, heating and air conditioning materials: Polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Four, steel structure materials: Polystyrene, extruded sheet, Polyurethane board, glass wool roll mat, etc.
- Q:What is acid refractory material?
- In fact, with the content of zirconia refractory multiple theory should also be acid refractory
- Q:It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
- The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
- Q:How long does it take for refractory cement to solidify?
- 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
