| 摘要 |
<p>The invention relates to a method for the production of an abrasive foam on the basis of a melamine-formaldehyde-condensation product comprising inorganic nanoparticles, with the following steps: Producing a solution or dispersion comprising a precondensate of the foam to be produced and inorganic nanoparticles, foaming the precondensate by heating the solution or dispersion from step, in order to obtain a foam comprising inorganic nanoparticles, and if applicable tempering the foam obtained in step), which leads to an increased abrasion when polishing delicate surfaces.</p> |
