Analysis of some existing problems of rust removal and sandblasting machine

Rust removal sandblasting machineIt is a kind of equipment for surface derusting. It uses compressed air as power to spray metal or non-metal particles as abrasives on the surface of the workpiece to be processed at high speed, and derust and clean the surface of the workpiece by impact and grinding. However, the conventional abrasives of the rust removal sandblasting machine, such as copper ore, ceramics, steel grit, steel shot, etc., are rushed to the surface of the steel plate due to the hard brittleness of their own materials and the pressure of compressed air during the sandblasting process. It turns into powder sand dust, and the generated powder sand dust will bring a lot of inconvenience to construction and environment. There are mainly the following problems:


One is environmental protection. After the rust removal sandblasting machine, most of the conventional abrasives have become powder and cannot be reused, so they have to be treated as waste materials, resulting in great waste. Even if metal abrasives with a saving rate of up to 80% are used, a certain amount of mineral dust and dust will be generated after sandblasting. This makes the sand removal, cleaning, and waste sand treatment of the rust-removing sandblasting machine heavy after the sandblasting treatment, and it is also necessary to arrange a waste storage yard. If you are not careful during the cleaning process, sand and dust will also be mixed into the air and affect the air quality.

The second is labor protection. In the process of sandblasting, the abrasive of the rust removal sandblasting machine is easy to become powder, and it will be scattered directly in the sandblasting working environment. The sand and dust floating in the working environment contain a variety of heavy metal components and the particles are extremely fine. , It can even penetrate workers' protective clothing and masks, so it is extremely harmful to the operators of the rust removal sandblasting machine. Workers who work for a long time in such an environment can cause toxic pneumonia or silicosis, and severe cases can lead to lung cancer. In addition, when the metal abrasive of the rust removal sandblasting machine impacts the workpiece, it will produce scattered abrasive debris, which bounces back on the body of the constructor, which will cause strong pain, and sometimes cause eye discomfort, injury and other eye injuries.
