Sand water use, should pay attention to what the problem?

(1) water jet sand particle size range.

Water jet sand is very fine, the common sand tube with diameter of 1.02mm, 1.27mm, 0.762mm, 0.508mm etc., if used for cutting particles uneven water sand, is prone to clogging of sand tube phenomenon, affect the normal cutting, very painful. So, water sand particle size range and particle concentration became of particular concern in the procurement of sand water users when the problem.

Garnet sand particles produced by fine water Chaowei, model, applicable to the domestic and foreign various brands, various types of water, does not produce plug phenomenon.

(2) water jet sand clean degree.

Water jet sand containing dirt and impurities and harmful substances, can also cause clogging phenomenon of sand pipe. Xinyi Chaowei new materials Limited production of water are being washed for four times and two times of separation, the dust is very small, clean, do not plug.

(3) water jet sand hardness.

Water sand hardness determines the number and scope of the use of abrasive cutting material. Low hardness water sand, cutting speed, cutting material is limited, use less. Corundum hardness above 9, cutting a wide range of cutting speed, but the drawback is that the hardness is too large, easy to wear and tear caused by sand pipe, reduce the water service life greatly.

Chaowei garnet sand jet Mohs hardness between 7.5-8.0, moderate hardness, can be used to cut apart from brown corundum, diamond and other stone, glass, tile, steel, cutting speed, good effect.

(4) the content of chloride water sand.

The chloride content is too high, easy to react with water, the formation of soluble salt, easy to produce sand in the inner wall of the pipe corrosion, corrosion, will block the sand tube, shorten the service life of water jet. The requirement for chloride content in the sand blasting process is below 25ppm (where ppm refers to the mass ratio of the solute to the mass of the total solution, used to indicate the concentration of the liquid).

Chaowei garnet sand water chloride content in 10-15ppm, very low chloride content, will not cause corrosion of water jet.
