Thermal insulation material is a new type of material whose thermal coefficient is less than 0.12. It is widely used in electric power, metallurgy, petroleum refining and chemical industry, especially in the field of heat preservation and insulation of boiler, flue, hot air duct, dust collector, oil tank, reactor and other equipment and pipeline.
Common thermal insulation materials are glass wool, rock wool, aluminum silicate, composite silicate, today Xiaobian will introduce the similarities and differences of these thermal insulation materials.
Glass wool: it is a kind of glass fiber material, mainly glass as raw material, after high temperature melting, high-speed rotation centrifugal tensile filament fibrosis and thermosetting resin-based environmental protection formula adhesive processing products, with strong hydrophobicity, high vibration resistance, low dust characteristics.
Rock wool: it is a raw material such as basalt, dolomite, after more than 1450 ℃ high temperature melting using high-speed centrifugal centrifuge fiber, at the same time into a certain amount of binder, dust, oil, hate water after approved by the cotton machine collection, pendulum method technology, combined with three dimensional method cotton-spreading after curing, cutting, forming different specifications and usages of rock wool products.Compared with glass wool, it has poor hydrophobicity, easy to disperse after rain, poor vibration resistance, and dust in construction, which is easy to stimulate the skin of construction workers.
Aluminum silicate: it takes natural fiber as the main raw material, adding a certain amount of inorganic auxiliary materials by composite processing made of thermal insulation coating, can form a kind of microporous network with high strength structure of thermal insulation layer.It has the characteristics of green environmental protection, water absorption and flame retardant, and stable sealing.
Composite silicate: it takes a kind of special non-metal as raw material, and a certain number of auxiliary materials, add binder and become.With convenient construction, can be arbitrarily cut, transportation and installation without loss and other characteristics.
These four kinds of insulation materials are more common in the field of industrial application, especially high-temperature resistant glass wool. Because of its slender and soft fiber structure, it has the advantages of high tensile strength, no slag ball, sound absorption and noise reduction, heat preservation and insulation, and high cost performance. It is widely welcomed by the market and has a broader prospect!
