The process of intercalation mecanoquu00ecmica of urea in the class of kaolin clay, delamination and obtain special metacaulim

摘要

The process of intercalation mecanoquimica of urea in the class of kaolin clay, delamination and obtaining metacaulim special. The present invention relates to the process of intercalation of urea in the class of kaolin clay by the method mecanoquu00edmico and subjecting the compounds resulting from the different interleaving processing to obtain materials with higher added value.Besides the direct use of the material interspersed with urea or delaminado, industry of ceramics and paper, the materials can be calcined directly or after crushing the dry or in the presence of water (delamination). The materials calcined lead to the award of u00e1xidos mixtures of aluminum and silicon nanomu00e9tricas dimensions, caused by the expansion of the structure after the burning of the urea.The metacaulim originated from this process and different from that obtained by the simple calcination of kaolin clay, because of their size and particle morphology.The main use of the materials from the calcination process of clay intercalated with urea is in the production of artificial high reactivity, with applications in additive of cement concrete for obtaining high performance and uses in industry of P. Olu00edmeros, rubbers and elastomers, adhesives, paints, soft abrasives, paper, pigments, ceramics,In addition to the other.
