What are the hazards of metal oxides and dust generated during thermal spraying

       There are many harmful factors in the thermal spraying process, mainly including: harmful gases, dust, light radiation, radioactive elements, noise, high-frequency electromagnetic fields, and potential fire and explosion. These harmful factors have a great impact on human health, the normal operation of equipment and the environment. Therefore, while promoting the application of thermal spraying technology, we must attach great importance to corresponding safety protection measures.



    Various spraying and spraying methods all use alloy powder as the deposited metal. Metal and alloy powders are heated and melted under the action of a high-temperature heat source. During the process of forming the coating, the powders will inevitably evaporate and splash in the field space, and float in the air. These harmful substances are more common in the process of thermal spraying, which is caused by the characteristics of the profession itself.



    The harmful effect of dust and its oxides on the human body is a relatively complex issue. The harm of these substances will accumulate for a long time, and gradually cause the human body to produce diseases, such as: rhinitis, respiratory diseases, silicosis and so on. In addition, the powder is very harmful to electrical equipment and mechanical equipment. For example, when it enters the electrical equipment, it will cause the danger of short circuit; if it enters the equipment, it will become abrasive, causing serious wear and tear of the equipment, affecting its accuracy and life.
