Garnet sandblasting to remove rust and less dust
Sandblasting is used in various industries. Sandblasting uses high-speed sand flow to clean the surface of the substrate. Previously, many materials such as quartz sand, river sand, copper ore, etc. were used. However, these materials have insufficient hardness. Will produce a lot of dust and free silicon harmful metals. Now with the improvement of people’s environmental awareness, they are slowly looking for safe and environmentally friendly dust-free sandblasting abrasives.
Nowadays, the widely used dust-free sandblasting abrasive garnet is favored by the majority of manufacturers and customers because of its low price and good quality, and it does not contain harmful substances such as free silicon. It can be used repeatedly to reduce the cost of use. Stone has obvious advantages and gradually replaces the original quartz sand and metal ballast.
Garnet sand is used as a sandblasting abrasive. Its specific gravity is high and the sedimentation speed is fast, so there is little dust during the sandblasting process, and the working environment will be better. At the same time, it is a silicon-free abrasive, free of free silicon and heavy metal components, and has no risk of harm to health and the environment. At the same time, the texture of garnet sand is relatively hard. The Al-Al garnet selected by our Rizhao Garnet Mining Industry has a Mohs hardness of 7.5-8, which is higher than other sandblasting materials, and the metal surface will not be broken during the sandblasting process. At the same time, it can be used repeatedly, generally it can be recycled for more than 8 times, and the relative cost of use is reduced.
