High hardness, high iron content, non-radioactive, and the United States a considerable white linen, the background of a gray, scattered gray Ma points, high-quality white marble, white linen, And the color is more unified so called white linen.

Processing method:
1. Saw natural granite into a sheet, the surface of the plate after the beginning of grinding, after the first mill on the fixed frame;
2. Flame burning is carried out on the surface of Shandong white hemp after initial grinding, which is characterized in that flame spraying adopts acetylene, oxygen, spray gun and flame uniformly to move on the board surface;
3. The moving speed is 120 ~ 250mm per second, the distance between the spray gun and the board is 20 ~ 40mm, and the inclination of the flame is 800 ~ 1000 ℃. Before the flame burning, Water spray.

In the selection of finished sheet, because the stone is a natural raw materials, can not be exactly the same texture, in the mining process level of the process there are differences. Most of the stone is divided into grades. Granite stone is not colored stripes, most only color spots, there is a solid color. One of the finer the better mineral particles.
