Fireproof rock wool board can be used as firewall?
Composite rock wool board and slag wool board referred to as mineral wool, slag wool has been widely used in metallurgy, machinery, building materials, petroleum and chemical industry in 1970s, rock wool used for external wall thermal insulation in developed countries such as the EU has a history of nearly 30 years, but in our country because of its high cost and production cost, the economic costs of organic insulation the material is greater than, the application range is not big.
You need to know what material the firewall is made of What are its standards and requirements? What's the function of it? When you know all about it, you won't take a piece of board to make a wall!
Rock wool board mainly by hydrophobic rock wool board pendulum method for production of insulation layer material, composite rock wool board is the natural rocks such as gabbro, Xuan Wuyan, dolomite, iron ore, aluminum and vanadium as the main raw materials, inorganic fiber adding binder, hydrophobic agent by high temperature melting, made of fiber the implementation of standards, GB/T25975-2010 is "building exterior insulation rock wool products"; rock cotton in the industrial slag blast furnace slag such as slag, phosphorus slag and fly ash as the main raw material, inorganic fiber after remelting fibrosis made. This paper introduces the main A-fire exterior wall external insulation system on the market (the following text from Chinese architectural design and Research Institute of standards "exterior insulation construction" Standard No. 10J121) the implementation of standards is GB/T11835-2007 "insulation rock wool, slag wool and their products".
