Metal waste acid pickling metallic material production process, the removal of material surface oxide layer (scale) acid react with the metal to form the corresponding acid salt, pickling salt when saturated, decrease the effectiveness of the pickling solution, Prices must be replaced hydrochloric acid, the resulting waste acid. Such waste acid composition is relatively simple, the main component of the residual acid, salt, and some production processes in mineral oil or acid mist inhibitors. Mechanical products processing hydrochloric wholesale market for mechanical surface treatment before plating parts hydrochloric acid pickling of the mechanical parts. Such waste acid hydrochloride salt complex composition mainly uses small amounts of waste acid every day, usually a batch process. Such waste acid in sulfuric acid, phosphoric acid based. Hydrochloric acid and inorganic chemicals in the field of medicine and organic drug production Hydrochloric acid is a strong acid, it is with certain metals, metal oxides, metal hydroxides, and most metal salts (such as carbonates, sulfites, etc.) , can react to form the hydrochloride salt. Therefore, in the production of many inorganic chemicals to use hydrochloric acid. In medicine a lot of organic drugs, such as novocaine, thiamine hydrochloride (vitamin B1 preparations), etc., are also made with hydrochloric acid. West Central hydrochloric acid, hydrochloric procurement, Zhengzhou Longda Chemical (certified merchants) are provided by Zhengzhou Longda Chemical Products Co., Ltd. Road Zhiyuan, temper forward. Zhengzhou Longda Chemical Products Co., Ltd. (www.longdahuagong.com/) aims to become and you win symbiosis, strategic partners to move forward, more determined to become the most influential of inorganic acid companies, and you leap together to success !
