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. In 1972, ASTM (American Society for Testing and Materials) developed a standard for mineral fiber spraying technology and construction specifications. In the 2000 revision of the ASTM standard, this material is referred to as SFRM(SprayedFire-ResistiveMaterial), which translates as spray fire retardant, and is defined as a material 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 Laboratory (UL) and the Canadian Underwriters Laboratory (ULC) contain a large number of different forms of building structures that apply spray inorganic fiber materials to achieve different fire resistance limits for design and user selection.
In addition to fireproof materials, inorganic fiber spraying is widely used in the field of building insulation. In 2003, China issued the building materials industry standard "mineral wool spraying insulation layer JC/T909-2003" to regulate the construction and application of inorganic fiber spraying insulation layer. In recent years, there have been frequent fires caused by building thermal insulation, especially the fire in the north side building of CCTV's new site. These frequent fires have led to increasing attention to the fire protection rating of thermal insulation materials in the domestic construction industry. The advantages of inorganic fiber spraying thermal insulation materials in fire protection A are very noticeable. 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.
