There are major differences between glass laser sandblasting machines and ordinary sandblasting machines in the following aspects.
In terms of processing objects, ordinary sandblasting machines are generally applied to sandblasting treatment of hard materials with relatively flat surfaces such as metal, plastic and wood. They are used to remove surface oxide layers and stains, so as to achieve a certain surface roughness or decorative effect. By contrast, glass laser sandblasting machines are specially designed for glass processing. As glass is brittle with high hardness, it imposes stricter requirements on sandblasting technology and parameters.
In terms of sandblasting media, common media for ordinary sandblasting machines include quartz sand and steel grit. The hardness and particle size of these media can be selected according to different processing requirements. Glass laser sandblasting machines generally adopt special media for glass such as aluminum oxide sand. With rounder particles, such media can prevent excessive scratches on the glass surface during sandblasting, and achieve ideal surface treatment effects on glass including etching and matting.
In terms of equipment structure and control system, glass laser sandblasting machine are equipped with more precise nozzles and air flow control systems, which guarantee uniform and stable sandblasting, and prevent local over-blasting or insufficient blasting on glass surfaces. The structure of ordinary sandblasting machines is relatively simple, which mainly focuses on processing efficiency and general applicability.
In terms of operation safety, stricter protective measures are required for glass laser sandblasting engraving machines. Fine glass debris is easily generated during sandblasting, and splashing debris may cause injuries to operators. Ordinary sandblasting machines have relatively lower safety protection requirements.
In conclusion, glass laser sandblasting machine and ordinary sandblasting machines have obvious differences in processing objects, sandblasting media, equipment structure and operation safety, and they are suitable for different sandblasting processing requirements respectively.
