History of Inorganic Fiber Spray Cotton

Release time:

Source:

The application of mineral fiber fireproof materials in foreign countries has a history of more than 100 years. Spray inorganic fiber fireproof materials appeared in the 1960 s, and the earliest spray inorganic fiber fireproof materials mainly used asbestos fiber as raw material. Later, due to the discovery of asbestos fibers have harmful effects on the human body, many places have clearly stipulated that the use of asbestos is restricted, and people have found man-made inorganic fibers as a substitute for asbestos. Man-made inorganic fibers are aluminum silicate wool, mineral wool, rock wool and glass wool, etc., which are all fibers formed by spinning after ore is melted at high temperature. 1972 ASTM (American Society for Testing and Materials)

In 1972,ASTM(American Society for Testing and Materials5) Formulated the technical and construction specifications and standards for mineral fiber spraying. Revised in 2000ASTM StandardThis material is referred to as SFRM(SprayedFire-ResistiveMaterial), which translates as spray fire protection material, and is defined as a material that is sprayed onto a substrate to provide fire protection to the substrate. It includes a sprayed fiber type material and a sprayed cement type material. The product service manuals published by the American Underwriters Laboratories (UL) and the Canadian Underwriters Laboratories (ULC) contain a large number of different forms of building structures, applying sprays.inorganic fiberMaterials reach differentFire resistance limitThe design number for design, user selection.
In addition to the availablefireproof materialIn addition, inorganic fiber spraying is used in large quantities.building insulationIn 2003, China issued the building materials industry standard "mineral wool spraying insulation layer JC/T909-2003" to regulate inorganic fiber spraying.Insulation layerconstruction and application. In recent years, the fire caused by the building insulation layer is frequent, especially in the new site of CCTVNorth wingThe fires are most well known, and these frequent fires have led to increasing attention from the domestic construction community.Thermal insulation materialThe advantages of fire protection grade, inorganic fiber spray insulation material fire protection grade A is very attractive. In this situation, the development of inorganic fiber spraying in the field of thermal insulation is very rapid, has formed a large market with an annual output value of hundreds of millions, and dozens of companies engaged in the development and construction of inorganic fiber spraying technology have emerged. At present, the design and use of inorganic fiber spray insulation in China is still growing rapidly, and will eventually form a large-scale emerging industry.
