Description
Technical field
The utility model relates to a kind of use for laboratory mineral wool production simulation proving installation, belongs to test apparatus equipment field, is used for fast, low cost realizes mineral wool and produce needed technical parameter.
Background technology
Mineral wool is through melting, fibroblast and with the cotton-like fiber of making after different organic and inorganic reagent surface treatments by all kinds of raw mineral materials, it is the general name of all kinds of inorganic non-metallic fiber and its products, comprise rock wool, mineral cotton, glass wool, aluminium silicate wool and goods thereof etc., wherein account for more than 70% with rock wool and mineral cotton.Mineral wool and goods thereof are a kind of high-quality, efficient heat-insulating material, are widely used in the insulation of the industries such as industry, building industry, transportation, shipbuilding industry, heat insulation, cold insulation, fire prevention.
It is the Britain in 19th century that mineral wool uses the earliest, enter the commercial production epoch to mid-term in 20th century, and become the substitute of asbestos, and being up to the present mainly used in building field, Britain accounts for 85%, Germany accounts for 70%, Japan accounts for 92%, the U.S. accounts for more than 90%.Starting late of domestic mineral wool industry, within 1958, just start research and production mineral wool, 1978, introduce first one from Sweden and there is world-class asbestos product production line, up to the present, although formed an effective insulating materials industry beginning to take shape, the particularly appearance of Chinese new architecture exterior wall insulating materials national standard, seem larger for the demand of mineral wool, but gap is still very large compared with developed countries.
Mineral wool fibres is to be obtained in the situation that chilling is stressed by silicate melt, and the similar glass of its structure, by random SiO
2network forms, SiO
2formed the skeleton structure of fiber, the kation adding may be arranged in the space of glass skeleton structure, also may replace the position of Si.Mineral wool is mainly made up of various oxides, the oxide of mineral composition cotton can be divided into acidic oxide (SiO according to character
