Q:What is the interior fireproof thermal insulation material?
The methods of thermal insulation wall have three kinds of materials. First: gypsum board or cement board are stuck outside the polyphenyl board; second: lightweight brick build; third: infill polyphenyl board, lightweight brick is built outside. The first two has almost the same price. The latter is slightly expensive. 60 yuan / square meter is not very expensive!
Q:Is there anyone who can explain how to grade the level of fire insulation board?
1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
Q:Who knows the fire endurance of B-level fireproof doors and windows?
B-grade fireproof windows refer to those fireproof windows whose fire retardant limit is not less than 1 hour. Technical requirements: I. Materials and Accessories (1) Window frame should have a certain strength to ensure the integrity and stability of the steel frame or the wood frame. (2) Steel frame and mound layer can employ galvanized steel sheet or stainless steel plate. Its selection criteria should be in line with the stipulation of the Article 5.1 of GB12955 "General Technical Requirements of Steel Fireproof Doors". (3) The selection standard of wood frame and mound layer should be in line with the provision of Article 5.1.1 of GB14101 "General Technical Requirements of Wooden Fireproof Doors". (4) Filling materials inside steel frame and wood frame should be non-combustible materials.
Q:What is neutral refractory? Can refractory suppliers tell the main components of it?
// Baike? Url x3d CQ3i6_yUCWUMgk3aaRGGLURNtvKPl5IdZpj35Yvommk7Nyif0IJD-SkdIW29GCHwLpb9cT9Ii25GLcEJg-ZHcq "target x3d" _blank "x26gt; http://baike.baidu.baidu.
Q:What kinds of refractory will be used in kiln of sintering ceramics?
Porcelain has many classes, including acid, alkaline and neutral materials.
Q:What are the best refractory materials in 2,400 Celsius degree?
It is the purpose that decides what kind of materials you should use. What you have said is 2,400 Celsius degree, right? It is about the fire resistance of the material or the required temperature of it?
Q:which kind of refractory is commonly used in the industry
Therefore it is known as special fire-resistant materials, such as yttria, high alumina raw material (sometimes neutral), olivine,which is used for alkalinity furnace, dolomite, and we roughly divided into several categories, beryllia, cerium oxide, these materials have a strong alkaline slag resistance, thorium oxide, lime, serpentine, which is picked from these refractory raw materials. the raw materials of basic refractory materials are mainly magnesia clay and titanium oxide, but because not many sources of raw materials, it can not be widely applied in the refractory industry, and we can analyze which kind of materal is processed by the pulverizer. There are many kinds of refractory materials, rotary kiln can only be used in particular circumstances. These materials have a variety of slag resistance at different degrees. the main material of special refractories is zirconium oxide. the refractory clay is the most basic and most widely used raw material in the refractory industry.
Q:What are the refractory materials above 1000℃
corundum would be fine
Q:How to divide the fire resistant level of construction thermal insulation materials?
Combining three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indexes for specific division. And it is mainly determined in accordance with the national standard GB8624 Building materials combustion levels.
Q:What is the fire resistance thickness of the thin fire-retardant coatings?
Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.
