Fan told Qiu aluminum products given that the aluminum cycle, it is essential classification of aluminum products, aluminum scrap in order to achieve. CNMn. However, this preprocessing, the currently relies heavily on labor. CNMn. In addition to low efficiency, the more difficult it is difficult to accurately and effectively classified. CNMn. For example, since the aluminum alloy can not be separated from the metal, so the cast alloy wrought alloy scrap is not suitable for production. CNMn. Some aluminum castings and aluminum, in the use of consumption is very small, they do not corrode aluminum products factory in Shenzhen, it can reach almost hundred percent recycled aluminum products factory in Jiangmen, which includes construction with aluminum, aluminum Fittings, and aluminum cans to mention the cabinet; more difficult to recover, in addition to the aluminum used on the chemical container chemical, as well as food, drug packaging materials, because it is difficult to release it from the aluminum composite aluminum aluminum weight The basic principle is that the chromate closed at dichromate aqueous solution, the oxide film adsorbed dichromate after chemical reaction to produce alkaline chromate aluminum [Al (0H) CrO4] dichromate and aluminum [Al (OH) Cr207], Yangjiang aluminum products processing plants, which product is filled into the membrane gap, which play a role in sealing. Dichromate sealing method generally used for protective anodic oxide film, the oxide film by closed after yellow, high corrosion resistance. However, the law does not apply to decorative or colored oxide film. Yangjiang aluminum products processing plants, aluminum products, Hongrun Hongrun by Dongguan Shijie Hardware Products Factory.
