Q:what is the grading standards of external wall thermal insulation materials?: 1. combustion performance of insulation material rates A EPS sea capacity module, rock wool, glass wool, foam glass, ceramic foam, foam cement, perlite obturator, etc. 2. combustion performance of insulation materials rates B1 Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule3 combustion performance of insulation material rates B2 Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 A graded insulation material is fire proof, but its thermal insulation performance is not so as organic XPS \ EPS. I feel the best insulation materials are Hairong EPS module. it is both insulating and fireproof and cheap. Insulation materials in the domestic market each has its shortcomings. Choose of materials should based on actualities in construction.

Q:What are the common refractory insulation cotton material?: High aluminum, clay brick, aluminum silicate fiber module and so on, inorganic types are glass wool, rock wool, foam glass etc.. Organic: the best one is phenolic foam, compround phenolic foam cement layer is a-level. Aerated concrete and other refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and compround thermal insulation material, expanded perlite, foam clay It is applicable for buildings that have high requirement for fire proof level, foamed concrete, volcanic ash glass.

Q:what grades are fire resistance of fireproofing glass divided into?: Fireproofing glass is a kind of special glass which can keep its integrity and thermal insulation performance in regular insulating refractory trials. and it can be divided into three classes according to its fire resistance: Class A, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. 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 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.

Q:How to choose construction external wall thermal insulation and fireproofing materials?: The width of fireproof partition shuld be greater than 30CM, and the thickness should be the same as total thickness of thermal insulation materials. Fire barrier zone thermal insulation board and base wall should be stuck in whole area. Fire Barrier zone thermal insulation board should be stuck with the assistance of anchor bolt which must press the mesh of the bottom layer. Fire Barrier zone should be set above the door and window, with a distance of less than 50cm between the lower edge of fire barrier zone and the upper edge of window.

Q:What is the role of adding chromium oxide green in unshaped refractory materials: Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.

Q:what is the common materials for home fireproofing material?: 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion

Q:What refractories have good mechanical property resistance and heat expansion and cold contraction property?: Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.

Q:Who knows the refractoriness of high temperature lightweight firebricks?: Hefei Jiu oak decor help you answer; the biggest feature is refractory: refractoriness 700.

Q:The classification of fire-resistant material: There are various refractory materials classified according to the chemical properties of material: Min< manufacturing technique: neutral refractory materials, pipes, etc. Standard model: baidu.hiphotos;8 simatic carbon composite refractory material zirconia based refractory material special fire-proof material 6; or a acute angle of 50～70° and material forms. 3.

Q:What kind of fireproof material is used for steel structure?: Fireproof material means the coating is with thickness 3 mm (including 3 mm) or less, good decorative effect, capable of expanding foam, fire endurance of generally within 2 h of steel structure fire at high temperatures. fire-resistant coating for steel structure is generally solvent-based systems, with strong bond strength, water resistance, weatherproof, good flowing property, decorative; it slowly expanded at high temperature to a dense layer of fire insulation, which has a strong refractory shock, delaying the rise of steel, protecting steel components. ultra-thin?intumescent?fireproof coatings?for steel?structure can be used by spraying, brushing or rolling, generally using construction steel with fire endurance within 2 h. new type of ultra-thin fireproof coatings for steel structure has a fire endurance of 2 hours or more, mainly using binding agents of polymethacrylate or epoxy resin and amino?resin and chlorinated?paraffin, which are of special structure, added with fire retardant system such as high degrees of polymerization, phosphoric?acid, dipentaerythritol, adding titanium dioxide, wollastonite and other inorganic refractory materials, solvent oil 200 # solvent composite. All kinds of light steel structure, grid and other use of this type of fire-resistant coating conduct fire protection. As such the fire retardant paint coating is ultra-thin, greatly reducing the amount of thin steel structure fire retardant coating, thereby decreasing the total cost of the project. The steel is protected and the fire is prevented.
