The invention relates to a ceramic scraper, which is used for powder spreading in the process of laser rapid prototyping. Both ends of an edge are provided with rounded corners, the upper part of the scraper is provided with screw holes, and thereby the ceramic scraper can be conveniently fixed on a scraper holder of a powder spreader. Since a conventional steel scraper has high ferromagnetism, in the process of powder spreading, the steel scraper can attract magnetic powder because of static electricity generated by friction, the magnetized powder can be easily agglomerated, as a result, the surface of a formed layer is uneven, the machining precision of parts is decreased, and even the interruption of a modeling process is caused. Since the ceramic scraper does not have ferromagnetism, the problems existing in the conventional scraper can be solved perfectly, the evenness of a powder layer is increased, and prototyping precision is improved. Moreover, since the rigidity of the ceramic scraper is high, the ceramic scraper has high wear resistance, furthermore, since the edge of the scraper is added with the rounded corners, friction force applied on the scraper can be further decreased, and therefore the service life of the scraper made of ceramic can be effectively prolonged. The ceramic scraper also has the advantages of simplicity in production, low machining cost, convenience in use and the like.

The nanometer clay modified silide composition for filming on polished brick consists of organic/inorganic composite silide adhesive in 100 weight portions, nanometer sheet silicate clay in 1.0-20 weight portions, surfactant in 7-15 weight portions, and nanometer oxide in 1.0-20 weight portions. The said composition is superior to available antifoulant and hard wax for polished brick and has excellent brightness, high antifoulant performance, good antibiotic performance, high wear resistance, and high chemical corrosion resistance. It is used to film on the surface of polished brick.
