    • The invention relates to a method for impregnation of porous objects comprising the following steps i)-v): i) applying an injection layer of a material comprising acrylic, epoxy or polyurethane onto the surface of at least part of the porous object and allowing at least part of said material to enter into the pores of said object utilising subatmospheric or superatmos- pheric pressure; ii) allowing the porous object to return to an atmosphere of normal pressure; iii) optionally at least partly allowing the injection layer to harden; iv) applying a topcoat of acrylic, epoxy or polyurethane onto the area of the porous object impregnated with the injection layer: v) allowing the topcoat to harden; wherein the injection layer applied in step i) and/or the topcoat applied in step iv) comprises pulverised glass having a particle size of 0 run to 100 μm. The invention also relates to porous objects obtained according to this method. The impregnated objects exhibits great strengths and resistance against wear of mechanical, chemical, thermal and/or biological nature.
    • 本发明涉及一种用于浸渍多孔物体的方法,包括以下步骤:i)-v):i)将包含丙烯酸,环氧树脂或聚氨酯的材料的注射层施加到至少部分多孔物体的表面上,并允许 所述材料的至少一部分使用低于大气压或超大气压进入所述物体的孔中; ii)允许多孔物体返回到常压气氛; iii)任选地至少部分地允许注射层硬化; iv)将丙烯酸,环氧树脂或聚氨酯的面漆涂覆在浸渍有注射层的多孔物体的区域上:v)使面漆硬化; 其中在步骤i)中施加的注射层和/或在步骤iv)中施加的面漆包括粒径为0nm至100μm的粉碎玻璃。 本发明还涉及根据该方法获得的多孔物体。 浸渍的物体表现出很大的力量和抗机械,化学,热和/或生物性质的磨损。
