Solidification/stabilization of industrial wastes using polyurethanes
Polimery 2002, No 11-12, 833
The results of solidification and stabilization of industrial wastes (metallurgical slag, lead smelting slag, flotation waste, scale), from various Polish factories, with using a polyurethane binder based on PMDI and one of following components containing OH groups: Rokopol G-l000, Terate 203 or water are reported. The effects of the type of a binder and its content as well as the type of waste on the density. hardness and compression strength of moldings of utilized wastes were investigated. It was stated that the type of a binder does not influence the properties investigated at a small range of binder content (up to 5.0 wt. %). From the economical point of view, using the PMDI/H20 system as a binder is the most justified.
