The operation of sandblasting processing technology and grasp the situation in a very large level of harm to the quality of sandblasting treatment, therefore, sandblasting work, the operation of dust-free sandblasting machine has strict provisions. The operating provisions in sandblasting work are as follows:

1, dust-free sandblasting machine as close as possible to the product workpiece, in order to reduce the length of the pipeline and working pressure damage, prevent too much pipeline damage, but also so that the construction team to contact each other;

2, in order to better avoid leakage and air release, reduce the moving frequency, improve the use rate of wear-resistant materials and work efficiency, should be carried out in an all-round way before the construction of the project to consider, scientific arrangement of the injection site, draw up the injection line;

3, sandblasting treatment hose to smooth, reduce pressure damage and wear-resistant materials on the hose of centralized damage, for the construction site must bend the area, often replace the position, so that the damage is symmetrical, increase the service life of the hose;

4, in the whole process of spraying, according to the gas working pressure, nozzle diameter, structural surface rust, the quality of the solution, high efficiency and other material to air ratio immediately adjust;

5. Depending on the working pressure of gas, the amount of sand and the environmental pollution of the structural surface, the nozzle moving rate can be easily grasped.

6, the surface preparation treatment, with dry rashness, diaphragm vacuum pump air compression to eliminate dust and debris, removed after the surface can not touch;

7. If the surface of the substrate metal material is found to be polluted or rusty before spraying, it must be solved again;

8. After the inspection and reaching the standard, the preparation treatment should be sprayed as soon as possible. The less time interval, the better. In the wet and cold or industrial production atmospheric pressure and other natural environmental standards, must be finished within 4h spraying, sunny days or temperature is not large, the maximum spacing is not more than 12h.
