The sandblasting treatment of natural stone (stone sandblasting surface) is to use angular emery, quartz sand, river sand and other abrasives to impact the stone surface under the drive of compressed air (or water) to obtain a kind of similar glass. Stone surface processing with frosted effect. So, today we will come to understand the sandblasting process of natural stone with the editor of FABULOUS Group.
1, suction dry sandblasting machine
The suction dry sand blasting machine is powered by compressed air, and the negative pressure formed in the spray gun by the high-speed movement of the airflow, the abrasive is sucked into the spray gun through the sand pipe and ejected through the nozzle, and sprayed to the processed surface to achieve the desired processing goal. . In the suction dry sandblasting machine, the compressed air is not only the power supply and the power but also the acceleration power.
2, press-in dry sandblasting machine
The press-in dry sandblasting machine is powered by compressed air, and the working pressure established in the pressure tank by the compressed air presses the abrasive into the sand conveying pipe through the sand valve and ejects it through the nozzle, and sprays it to the surface to be processed to achieve the desired Processing items. In the press-in dry sandblasting machine, the compressed air is not only the material supply power but also the power and the acceleration power.
3, liquid sandblasting machine
Compared with dry sandblasting machine, the biggest feature of liquid sandblasting machine is that it can well control the dust pollution in the sandblasting process and improve the working environment of sandblasting operation.
The liquid sandblasting machine uses the grinding liquid pump as the feeding power of the grinding liquid, and the evenly stirred grinding liquid (mixed liquid of abrasive and water) is delivered into the spray gun through the grinding liquid pump. As the acceleration power of the grinding liquid, compressed air enters the spray gun through the air pipe. In the spray gun, the compressed air accelerates the grinding liquid entering the spray gun, and is ejected through the nozzle and sprayed to the processed surface to achieve the expected processing purpose. In the liquid sandblasting machine, the grinding fluid pump is the power supply, and the compressed air is the acceleration power.
