Stone processing sandblasting dust-free process

The steel grit is sprayed in a high-pressure vessel through a nozzle to strike the marks formed on the surface of the stone, and the desired pattern or rough surface is obtained, which is the dust-free sandblasting process of the stone. The main thing of this kind of process is to use the dust-free sand blasting machine, which is different from the sand blasting machine used for the large-area processing sandblasting board in that the sand blasting force is larger, and even the embossing height difference is 5 ~ 8mm pattern, used to spray fonts, patterns, art paintings are very new and unique. The general sand blasting machine only reaches the rough surface. In addition, the dust-free technology uses vacuum to instantly recover the sand dust, which has a good protection effect on the operator and the environment. The operation process is as follows:

(1) Select sand blasting machine and steel sand. The technical indicators can be found in the table below.

(2) When the time is used to cover the stone through the template, the size of the template and the finished product after processing shall be 1:1. The permeable template is made of reinforced rubber or high-strength resin and then laser-cut. If you want to make a positive (convex) text (pattern), you must keep the words in the template. If you want to make the word (pattern) into a concave (female) pattern, you should dig the word or pattern.
