- Q: who knows the fire resistant levels of fireproofing glass?
- Fireproofing glass is a kind of special glass which can keep its integrity in the regular fire resistance test, and it can be divided into three classes: fireproofing glass,fireproofing glass A class is a kind of fireproofing glass that can satisfy the requirements of refractory integrity, fire resistance and thermal insulation. Including composite flameproof?glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements. hope it can help you.
- Q: Can quantitative feeder be used in refractory plant? Thank you
- Feeder experts, justice and analysis, quantitative feeder, of course, can be used in refractory plants
- Q: What is the strength of high strength refractory material?
- Refers to constrcuting through ramming, and a refractory materials that is hardened in temperature higher than normal. mixed through a certain grade of refractory aggregate, powder, binder, additives, water or other liquids. Can be classified into high alumina and fireclay, magnesite, dolomite, zirconium and silicon carbide by the standard of texture.
- Q: How to distinguish the fire?rating of rubber and plastic thermal insulation material?
- It is divided into level A, B1, B2 and B3. According to the current "burning behavior of building materials classification method", Level A insulation material is a non-combustible material, which belongs to YT. However, from the point of view of the current market , level A insulation material are very few, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the more welcomed by the market is the organic insulation material. This is characterized as thermal insulation material, which is divided into three levels: level B1 is flame retardant, level B2 is flammable and level B3 is flammable. The level B1 nonflammable thermal insulation material is determined according to the fire endurance of the material. And different parts of the material are divided differently! Such as the common EPS / XPS insulation boards through special treatment of adding flame retardant. . Level B2 combustible insulation material is commonly the EPS expanded polystyrene foam insulation board and XPS board, that is, the ordinary plate. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Level B3 flammable insulation material is commonly the thermal insulation material taking polystyrene foam as the main material. Since this material is highly flammable, it has been out of the external wall thermal insulation materials. As for the civil construction insulation materials, China's current popular building insulation materials in the market are mainly made of three organic foams: EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane).
- Q: What are the requirements of refractory temperature of refractory brick?
- Refractoriness can reach 1690 degree, but the highest operating temperature is 1350 degree. If the temperature goes higher, operation life will be greatly shortened.
- Q: Who can tell me about the foundry refractory materials?
- Such as: neutral, alkalic, acidic refractories. Of course, the raw materials of different materials are not the same. Such as: the magnesia-carbon bricks, basic refractory materials: magnesite(electric?smelting, high-purity)+ crystalline flake graphite+ phenolic resin+ additive (aluminate or silicon powder or silicon carbide powder or high-temperature pitch) and so on.
- Q: What is the material composition of the new fire-resistant coating?
- The basic composition of thick coating steel structure fire is: Binder (Portland cement, magnesium oxychloride or inorganic high-temperature bonding agent), aggregate (expanded vermiculite, perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifiers , hardening agent, waterproofing agent) and water. Fireproof coating binders Portland cement, magnesium oxychloride cement and an inorganic binder of the fire-resistant coating for steel structure base material. The conventional inorganic binder include alkali metal silicates and phosphates substances.
- Q: What refractory material does cupola lining use?
- Refractories for ehongtianlu, Yong, eajliao, najhuo cupola, refractory (refraetoriesfo:Cupola, furnace) masonry cupola and related parts. The utility model also discloses a heating furnace, which is a thermal equipment for melting pig iron in the casting industry and certain steel smelting plants. The working temperature of the guard is usually 1400 ~1 stone.. C.
- Q: What are the additives and recipes of refractory?
- Trimeric major role played bulk water reduction effect can be considered strong trimer strong bleeding effect'm sure Hey lignin sulfonate water-reducing effect of the strong retarding superplasticizer effect in two critical recommendations with more money to buy homes are equipped who is willing to disclose ah experiments to solve the problem through Chuk Wan
- Q: Who knows about the B-level fireproof insulation materials?
- Commonly used B-level materials: Molding polystyrene foam, extruded polystyrene board, gelatine powder polyphenyl granule heat insulating slurry. Although the polyurethane is not the commonly used material, but the 9mm composite of monolayer gypsum board and PU insulating material can reach B-level.
