AbstractThe chemical structure of mineral wool fiber was investigated by using Fourier Transform Infrared Spectroscopy (FTIR). Next, the glass transition temperature and the crystallization temperature of the fibers were studied. Finally, the crystallization kinetics of fiber was studied. The results show that the chemical bond structure of fibers gets more random with the increase of acidity coefficient. The crystallization phases of the fibers are mainly melilites, and also a few anorthites and diopsides. The growth mechanism of the crystals is three dimensional. The fibers with acidity coefficient of 1.2 exhibit the best thermal stability and is hard to crystallize as it has the maximum aviation energy of crystallization kinetics.

Mineral wool is a type of important material for basic infrastructure development and national economy. It is widely used as insulation material in construction industries. Some high temperature industrial solid waste materials, such as blast furnace slag, cyclone slag and some metal slag, after composition adjusting and reheating, can be directly used to produce mineral wool. The recycle of residual heat in the hot solid wastes can decrease the cost of mineral wool and is beneficial for energy conservation, environmental protection and social sustainable development. The development and technical characteristics of mineral wool production with blast furnace slag, cyclone slag and some non-ferrous metal slag have been analyzed in this paper, and the energy conservation technique in managing high temperature solid waste has been also discussed.

A facile and highly efficient FeF3-catalyzed method has been developed for the direct synthesis of functionalized dihydropyrimidines from readily available starting materials via Biginelli reaction. These reactions proceed at low-catalyst loadings with high functional group tolerance under mild conditions. This method provides efficient reusability of the catalyst and good to excellent yields of the products, making the protocol more attractive, economical, and environmentally benign. FeF3 is an attractive catalyst for the Biginelli reaction because of its high acidity, thermal stability and water tolerance.
