In actual use, for different surfaces and different application requirements, how to control the treatment effect of pavement shot blasting machine? The surface after shot blasting achieves different treatment effects and meets different specifications and standards. It is necessary to adjust the process control of the pavement shot blasting machine to meet the requirements of different surface conditions. How to control the treatment effect of pavement shot blasting machine?
(1) Selection of steel shot specifications. Standard steel shots have different sizes and shapes. Steel shots of different diameter ranges can be selected according to the material and roughness of the surface to be treated. The treatment of steel plate surface also requires the addition of a certain proportion of steel sand to achieve the required roughness.
(2) Shot flow control. Adjusting the flow rate of steel shot can adjust the shot density per unit surface area, thereby achieving different shot blasting effects.
(3) Travel speed of pavement shot blasting machine. The pavement shot blasting machine can set and adjust the travel speed. As the travel speed decreases, the depth of surface treatment increases. Generally, the surface treatment depth of cement concrete can reach 0.1 to 3 mm, and the maximum can reach 4 mm. The texture depth of asphalt concrete pavement can reach 2.5 mm. How to control the treatment effect of the road shot blasting machine?
By adjusting the relationship between the three parameters of shot size and shape, the travel speed of the equipment and the shot flow rate, different treatment effects can be obtained to ensure that the surface after shot blasting reaches a relatively ideal roughness.
