What Are The Advantages Of Sponge Sand Blocks?

The sponge sand block is based on foam plastic, which has good elasticity and deformation, and does not scratch the workpiece. According to the shape of the workpiece, sponge sand is used after washing. It is widely used in the grinding of various irregular and complex processed cotton, manual grinding of special-shaped surfaces of wood, metal, plastic, paint and other materials, household and kitchen cleaning supplies.

The sponge sand block is made of foam sponge covered with alumina, chemical viscose, soft and durable. It can polish, arc or engrave concave-convex lines on the surface of irregularly shaped metal and wood products, and is suitable for the surface of non-deformed metal and wood products. In addition, the sponge sand is based on a highly elastic sponge sponge as a carrier, and the viscose is coated with abrasive, and the abrasive particle size is 80-400.

The sponge sand block has the characteristics of high density, good flexibility, high toughness, good self-grinding, low sand consumption, recyclability, good polishing finish, stable chemical composition, wear resistance, acid and alkali resistance, etc. In the continuous grinding and grading process, the grinding shell with sharp edges and sharp edges can break to form new cutting edges, making its grinding performance better than other abrasives. In particular, sponge polishing sand has become the first choice for effectively solving the abrasive grains of CNC polishing process due to its high hardness, high specific gravity, stable chemical properties and unique self-grinding properties, and is also an ideal polishing material.
