Thermal treatment of the mineral wool mat

摘要

The operational stability of mineral wool materials is largely determined by the uniformity of polycondensation the binder in the material volume. For optimization the thermal treatment parameters software system was designed, and it's been tested in technology of layered products.The operational stability of mineral wool materials is laid at the manufacturing stage of these products, and it's defined by the properties of raw materials and the conditions of formation the structure and its stabilization during the thermaltreatment .Properties of the mineral fibers (in particular the resistance to aggressive environments) are estimated by module acidity, for mineral wool produced from natural stones (basalt, gabbro, porphyrite) - stone wool it is in the range from 1,8 to 2,2. Formation conditions of the material structure should provide maximal intersection of fibers while maintaining the uniformity of the structure. It is achievable by volume fiber orientation. Stabilization of the structure is achieved during thermal treatment by polycondensation the binder.In this process very important parameters are a uniform distribution of binder, the maximum polycondensationof the binder and the maximum uniformity polycondensationof the binder.
