There are two main production methods of Copper Acetate: wet and dry. The raw materials used in the wet process are generally copper wastewater, which results in low main content of copper acetate products, high content of heavy metals, poor product quality, and serious environmental pollution. Therefore, it is currently difficult for companies adopting this process to be in the industry Survival, copper acetate produced by this process is generally used on ordinary pigments; the raw materials used in the dry process are relatively pure, the main content of the product is about 98% -99%, and the content of heavy metals is generally 100ppm, and the content of acid insolubles is extremely easy to exceed the standard .
