Does the production process produce toxic substances? What is the impact on the body? Does the production of coated aluminum also produce toxic substances?
High temperature hazards The current national standard "high temperature operation classification" stipulates that the workplace average WBGT index is equal to or greater than 25 ℃ operation, that is, high temperature operation. Aluminum electrolytic cell electrolysis temperature up to 940 ℃ ~ 960 ℃, is the main production heat source. Carbon section of the calcination, roasting, continuous mixing, preheating spiral, asphalt melting production equipment are production heat source. The data show that the response speed, the computing power, the sensory sensitivity and the coordination function of the sensory movement are obviously decreased when the ambient temperature reaches 28 ℃. High temperature to reduce labor efficiency, increase the operating error rate. Mainly reflected in the body's body temperature regulation and water metabolism and circulatory system. High temperature can also inhibit the central nervous system, so that workers in the operation process of distraction, muscle work ability to reduce, resulting in injury accidents.
Dust hazards Aluminum plants in the production process of dust mainly aluminum oxide dust, petroleum coke dust, asphalt dust. Alumina dust mainly exists in the electrolytic plant, the alumina storage and transportation system; the calcining section of the feeding system, nesting system, calcined after the section of the kneading machine, preheating screw machine and milling system dust and asphalt smoke; There are asphalt smoke generated; residual processing section of the coarse crushing, ingredients, screening and other processes are dust generated. Crane driver, electrolysis workshop workers, carbon powder broken, screening and other workers by the dust hazard. According to TJ36-79 "industrial enterprise design health standards" provides that the workshop the maximum allowable concentration of harmful substances in the air, the dust in the production of alumina dust should not exceed 6mg / m3; other dust (when the free silica content of 10% ) Shall not exceed 10mg / m3.
