What are the production processes of exhaust gas produced by auto parts? 1. Stamping: that is, the steel plate is pressed into the shell of the car using a punching machine. 2. Welding: Welding is to solder each stamped part first. 3. Painting: After the welding process is completed, the car body is entered into the painting workshop, phosphating treatment, painting treatment. The harmful gases mainly come from the coating process, which will emit benzene, toluene, xylene and other harmful gases. Our company provides ASD5300C toxic and harmful gas detector and JB-TB-ASD5100 alarm controller.
Chemical fertilizer production process will produce waste gas, ammonia, carbon monoxide, carbon dioxide, sulfur dioxide, hydrogen sulfide and other harmful gases. Exposure to high concentrations of harmful gases for a long time will have different degrees of adverse effects on the body.
Large shopping malls because of relatively dense personnel, poor ventilation, will produce carbon dioxide gas, carbon dioxide in shopping malls is 3 times higher than outdoor. This can lead to a lack of oxygen, which can cause discomfort.
During the production of bread and pastries, carbon dioxide gas is produced by yeast fermentation and baking. Low concentrations of carbon dioxide are not toxic, but high concentrations can cause poisoning.
Under the action of high temperature and strong ultraviolet light produced by welding arc, a large number of toxic gases will be produced around the arc area, such as carbon monoxide, nitrogen dioxide and other gases, and long-term contact will cause a certain degree of damage to the body.
