aluminum blunt agent

aluminum environmental protection passivator is a kind of scale remover specially designed for aluminum and aluminum alloy. The solution does not contain nitric acid, phosphoric acid, hydrofluoric acid, no yellow smoke and toxic and harmful gas release during operation, and no phosphorus discharge for waste water. It conforms to the national environmental protection policy and is suitable for die-casting aluminum with high silicon content. The surface color of the aluminum alloy die casting before processing is different, which is not conducive to the subsequent processing. After using aluminum environment-friendly passivating agent, the surface of the die casting forms a uniform silver white, which provides a good substrate surface for the subsequent processing.
