What are the factors that affect the effect of sandblasting?

 The automatic sandblasting machine removes particulate matter from dusty gas to reduce its emission to the atmosphere. Dust-containing industrial waste gas may be produced in mechanical processes such as crushing, screening, conveying, and blasting of solid materials, or produced in processes such as combustion, high-temperature melting, and chemical reactions. Contact us to get sandblasting machine price right now.

1. Strength of sandblasting equipment

The main process parameters that affect the intensity of blasting are: blasting diameter, blasting speed, blasting flow, and blasting time. The larger the diameter of the sand blast, the faster the speed, the greater the intensity of sandblasting, the stronger the collision of the workpiece, and the greater the intensity of sandblasting. Sandblasting strength requires a certain amount of sandblasting time for the sandblasting machine to ensure that the sandblasting intensity reaches saturation within a certain period of time, and the sandblasting time is prolonged and the intensity no longer increases significantly. In the sandblasting strength test, the characteristics of the sandblasting strength are improved through the deformation of the test piece. Now contact us to get a cheap sand blaster machine factory price.

2. Sandblasting coverage

Factors affecting coverage include material hardness, blasting diameter, injection angle and distance, and blasting time. Under the specified sandblasting intensity, when the hardness of the workpiece is lower than or equal to the hardness of the standard test board, the coverage can reach 100%. Conversely, the search speed will decrease. Under the same blasting flow, the longer the distance between the nozzle and the workpiece, the smaller the jet angle, the smaller the blasting diameter, and the shorter the coverage required time. When the blasting strength is increased, the blasting, injection angle and distance of the appropriate size should be selected to achieve the required value. Click here you can check our sandblasters for sale.

3. Surface roughness of work piece

The factors that affect the surface roughness are the strength and hardness of the material, the diameter of sandblasting, the angle and speed of sandblasting, and the surface roughness of parts.

Under other conditions, the strength and surface hardness of some materials are higher, the plastic deformation is more difficult, the shallow hole is shallow, the surface roughness value is small, the diameter of the sandblasting is smaller, the speed is slower, and the lighter crater , The surface roughness is small. The larger the jet angle, the smaller the blasting speed, the smaller the impact pit, and the shallower the tangential velocity. The greater the tangential velocity, the greater the impact of sandblasting surface grinding and the smaller the surface roughness. The surface roughness of parts is also one of the influencing factors. If you are looking for portable shotblasting machine for sale, please leave your message.
