Laizhou Qiyuan Plastic Products Co., Ltd It is a joint-stock enterprise integrating scientific research, development and production. The company was founded in 1992. After 28 years of development, it has now developed into a provincial standardized enterprise with an annual income of more than 50 million yuan. The enterprise has a strong technical research and development force. It has more than 20 engineers and technicians, more than 20 sets of testing and testing equipment, and has advanced equipment production lines in China. It is a contract abiding and trustworthy unit in the rubber industry system of Shandong Province, and a AAA level unit in the financial system. Company produced Sandblasting pipe Also called high pressure hose for sand blasting, it is applicable to pressure shot blasting for rust removal of metal surface working style, basting and sand blasting high pressure hose for wet sand blasting and dry sand blasting in construction. During the whole process of sand blasting of sand blasting pipe, the surface of product workpiece will have a relatively inconsistent density. What is the reason for such a situation?

1. The moving speed of the spray gun is unstable during sand blasting. When the moving speed of the spray gun is relatively slow and the moving speed is relatively fast, the sand sprayed by the two is the same in unit time, but the sand spread over the total area is small in the front and large in the second, because the same amount of sand spreads over the surface of different total areas, which will inevitably lead to different densities.

2. The standard air pressure of the automatic sand blasting machine is unstable during the whole operation process. When an air compressor is used for several spray guns, it is difficult to stabilize the standard air pressure. When the standard air pressure is high, more sand will be sucked in and sprayed out. When the pressure is low, the reverse is true, that is, the amount of sand sucked in and sprayed out will be less. When more sand is sprayed, the sprayed sand surface must look dense, while when less sand is sprayed, the sand surface must be sparse.

3. The spray gun mouth is too far away from the surface of the product. When the nozzle of the spray gun is close to the surface of the product, the spray area is small, but it is relatively centralized and looks dense. When the nozzle of the spray gun is far from the surface of the product, Sandblasting pipe Although there is still so much sand sprayed, the total area of sand sprayed has expanded, and it will look rare at this time.
