Basaltic continuous multifilament yarns ageing in aggresisve alkaline medium.Kinetic model

摘要

The kinetic regularities of the breaking force reduction and the mass loss at the basalt roving ageing in alkaline media have been ivnestigated.The obtained equations take into account the reduction of the basaltic fibr breaking force causedby the occurrence of adsorption processes and partial chemcial dissolution (etching) of the surface layer basalt components in aqueous alkali solution.The obtaine dregularities cna be used for the prognosis of the tensile strength reduction of basalitic fiber materials under prolongedaction of alkaline aggressive media.
