Processing methods of Shandong white hemp

Shandong white hemp has a high surface finish, corrosion resistance, acid and alkali resistance, high hardness and density, extremely low iron content, and no radioactivity. It is famous for Shandong white hemp, which can be divided into large flower, Chinese flower and small flower. The processing method of Shandong white hemp is as follows: First, the natural granite is sawn into plates, and the surface of the plate is initially ground. After the initial grinding, it is placed on a fixed frame
, and then the surface of the Shandong white linen after initial grinding is flame-burned. The characteristic is that the flame spray Acetylene, oxygen, and a spray gun are used for burning. The flame moves evenly on the board. The moving speed is ~mm per second. The distance between the injection tool and the board is ~mm, and they are at an angle to each other. The temperature of the flame is ~℃, spray water on Shandong white hemp before burning with flame.
The processing method of Shandong white hemp can be roughly divided into the above three steps. Shandong white hemp minerals have stable chemical composition, dense rock structure, strong acid resistance, low stone porosity, difficult chemical changes on the surface, and do not contain any harmful substances. Minerals have high wear resistance and hardness, strong weathering resistance, and excellent physical properties.
