Is the modifier used for aluminum treatment toxic?

it depends on how you refine waste aluminum melt with chlorine-containing substances. Although the effect is good, its by-products AICI3, HCl and Cl will cause serious damage to human body, environment and equipment. In recent years, people are trying to improve the treatment process and choose non-toxic and low-toxic refined metamorphic materials to solve the environmental pollution problem, such as N2 and Ar as refining agents, but the effect is not satisfactory. The so-called "pollution-free" refining agent on the market, whose basic components are carbonate, nitrate and a small amount of C2C16, can not completely eliminate environmental pollution because there are still a small amount of nitrogen oxides and chlorine gas discharged. In recent years, the newly developed process of modifying, refining and refining recycled aluminum with rare earth alloys is expected to completely solve the environmental pollution problem of waste aluminum recycling and smelting industry. The process makes full use of the interaction between rare earth elements and aluminum melt, and gives play to the refining, purification and modification functions of rare earth elements on aluminum melt, which can realize the integrated treatment of aluminum melt purification, refining and modification, which is not only concise and efficient, but also can effectively improve the metallurgical quality of recycled aluminum. No harmful waste gas and other by-products will be produced in the whole process of treatment.
