Q:Who knows what is the standard of insulation material whose fire proof is level A?
Fire insulation materials of level A is non combustible building materials, and does not have any burning material. Level A1: single inorganic non combustible, no open flame. Level A2: A2 level: composite organic non combustible, that is, composite materials, non flammable, smoke volume should reach the standard.
Q:what's the varieties of thermal insulation material with A level fire rating?
the main A level fireproof material is rock wool now (note:it is rock wool not mineral wool). A1 level fireproofing, now the largest producer is Taishi rock wool Co., Ltd.; hope my answer can help you, thank you.
Q:Why the corundum can be used as refractory
Because the main component of corundum is aluminum oxide!
Q:What are the characteristics of phenolic resin as a refractory material?
Q:The history of refractory material
Q:Who knows the fire resistant level of the rock wool color plate?
The rock wool color steel rock wool board is used in a area of high ​​fire safety requirements. According to "interior decoration of buildings for fire protection design", the color steel rock wool board belongd to level A. Its life is more than 15 years and still can be used when the temperature is up to about 700 ℃, with maximum fireproofing hour of six hours. And the rock wool color plate is a environmentally friendly material, the preferred material in the construction industry .
Q:How is refractory material made?
It is made from carbon materials.
Q:How to distinguish the fire resistant level of construction materials?
Building materials fire resistant level is divided into four levels, among which the first level is the highest, with strongest fire resistance; fourth level is the lowest with weakest fire resistance. Fire resistance level of buildings depends on combustion performance and fire endurance of the building components. The building components refer to a series of basic components such as the building walls, foundations, beams, columns, floors, stairs, ceiling, etc.
Q:What materials is silicious thermal insulation board made of?
Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
Q:what materials can make external wall fireproofing paint have the fireproofing effect
First, the width of fire barrier is greater than 30CM, and the thickness should be same to the thickness of insulation material. fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. the thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Cement foam insulation board is recommended to use as external insulation board materials, level A exterior wall cement foam insulation board is a new ultra-lightweight thermal insulation material, with the advantages of lightweight concrete and insulation performance, with characteristics of low production costs, simple process, easy to operate, small product density in 180250kg / m3, high strength, low water absorption and good insulation properties, thermal conductivity of 0.05 ~ 0.07W / m · K and level A non-combustible; it is suitable for external wall insulation and fire isolation belt, and can meet the urgent needs of the market of exterior thermal insulation. With the increase of the intensity of the building fireproofing, the products will become the leading products in building insulation market in the future.
