The potential of wastewaters from the galvanic industry treated to remove toxic heavy-metal contaminants for the manufacture of commercial products lies in the development of processes for their reuse. This research addresses the feasibility of employing galvanic waste in the production of powder coatings. Powder waste generated through the resource-saving ferritic method and electroerosion dispersion method is significantly safer for the environment than that generated through reagent methods. Coatings resulting from wastewater treatment exhibit mechanical properties that meet current industry standards. The introduction of 15 wt.% spent polyvalent iron oxide sorbent into paint coatings enhances their mechanical performances. Specifically, the rebound strength increases from 20 to 40 cm/kg and tensile strength from 5 to 7.4 mm, the bending strength decreases from 8 to 5 mm, and the corrosion resistance of the coatings improves by 1.5 times compared to the standard samples. These improvements are attributed to the introduction of chemically and thermally stable crystalline phases possessing ferromagnetic properties into the coatings. As a result, these coatings increase shielding against electromagnetic radiation in the megahertz range by three times compared to the standard coatings. A significant research finding is the potential for reusing ferromagnetic waste from the galvanic industry in specialized materials.

电镀工业废水经过处理以去除有毒重金属污染物以用于商业产品的制造的潜力在于开发其再利用工艺。这项研究探讨了在粉末涂料生产中使用电偶废物的可行性。通过资源节约型铁素体法和电蚀分散法产生的粉末废物比通过试剂方法产生的粉末废物对环境显着更安全。废水处理产生的涂层表现出符合当前行业标准的机械性能。将 15 wt.% 废多价氧化铁吸附剂引入油漆涂料中可增强其机械性能。具体来说，与标准样品相比，回弹强度从20厘米/千克增加到40厘米/千克，拉伸强度从5毫米增加到7.4毫米，弯曲强度从8毫米减少到5毫米，涂层的耐腐蚀性能提高1.5倍。这些改进归因于在涂层中引入了具有铁磁性能的化学和热稳定结晶相。因此，与标准涂层相比，这些涂层对兆赫范围内电磁辐射的屏蔽能力提高了三倍。一项重要的研究发现是在特殊材料中重新利用电镀工业中的铁磁废料的潜力。
