The sandblasting gun for the inner wall of the pipeline can simultaneously obtain the required cleanliness and a certain roughness of the surface to be cleaned, and improve the adhesion of the coating on the basic surface. No matter how good the coating is, it cannot adhere to the surface of the workpiece without surface treatment for a long time. The role of surface pretreatment is to clean the surface and create the desired roughness on the surface to "lock in" the coating. After the surface of the sandblasted workpiece is coated with an industrial coating with good performance, the coating life can be more than 3.5 times longer than the same quality coating on the surface treated by other methods.

Equipment use.

Pipeline blasting gun equipment has been widely used in machinery manufacturing, instrumentation, medical equipment, electronic appliances, textile machinery, printing and dyeing machinery, ceramics, handicrafts, machinery repair and many other fields. As a conventional sand treatment equipment, sand blasting equipment has been continuously developed, improved and perfected. It has a unique processing mechanism and a wide range of processing and application. Sand blasting equipment is more and more popular in today's surface treatment industry.
