The strong phenomenon of sandblasting helmets blowing up sand particles and impacting the surface of objects is a natural phenomenon of grinding the surface of objects.
In 1870, the American BCTilghman was patented for a high-pressure injection device. Most of the basic structures and related matters of various sand blasting devices in use today were invented and inspected at that time.
Today, whether dry or wet, there is a surprisingly wide range of industries that use sandblasting. There are also many types of sand blasting devices. Judging from the past developments, there is no doubt that their application fields will expand in the future.
At the time Tilgman invented the sand blasting device, many of the practical peripheral technologies had not yet been developed. If there is no high-performance air compressor, high-pressure water vapor is used instead. As for the mechanical projection type high-speed slewing wing, due to the unknown unknown dangerous speed and the unsatisfactory structure, sufficient projection force cannot be obtained. Because the abrasive uses natural gravel, it is not only easy to break and wear the accelerator structure, but also generates a lot of dust and deteriorates the working environment.
The development of iron abrasives instead of natural gravel has contributed to the advancement of rotary wing projection sandblasting devices. The improvement and popularization of air compressors have promoted the high performance of projection method devices. And research and development of the use of various abrasives, etc., the development of sandblasting equipment has now passed quite a long time.
