          Hydrochloric acid all kinds of packaging specifications hydrochloric acid product details
          Product level: Industrial grade Color / Appearance: colorless Implementation of quality standards: GB320-2006 Content: can be customized

          Hydrochloric acid Products::
          Ultra-low impurity SO42- content, low Fe salt content of hydrochloric acid
          Hydrochloric acid is an aqueous solution of HCl gas, pure hydrochloric acid is a colorless transparent liquid, and industrial hydrochloric acid often contains trivalent iron salts, free chlorine and other impurities with yellow. In addition, industrial synthetic hydrochloric acid also often contains a certain amount of sulfate impurity ions.
          The main factors affecting the superiority of hydrochloric acid are SO42-, Fe impurities. Chlorine products contained in the excess chlorine impurities, in the course of the use of free chlorine will be distributed out of the environment pollution. Removal of impurities in hydrochloric acid process is the purification method, the current use of "industrial synthetic hydrochloric acid" chemical standard GB320-93 as a reference.
          Meilan Chemical by the technology center R & D process support, hydrochloric acid products, skilled processing, in strict accordance with the chemical standard GB320-93 production and production of hydrochloric acid products with high purity, less impurities, especially ultra-low SO42- content of hydrochloric acid and low Fe salt The content of hydrochloric acid, product quality and stability.





                                                  
          Flexible Product Specifications:
          I plant hydrochloric acid technology to deal with skilled, in strict accordance with the chemical standard GB320-93 production, product variety, according to the special requirements of users customized products.
           
          Product quality assurance:
          Meilan Chemical has a safety production license specification, its own brand of agricultural and commercial licensing, hydrochloric acid production of precursor chemicals permit specification. Hydrochloric acid from the coarse material, intermediate products, the final products are achieved on-line monitoring to ensure that the factory product pass rate, while further ensuring the superior product rate and its stability. The company has a sound quality management, monitoring and testing system, the factory of any product can provide the relevant product quality tracking test report.
           
          Product application areas:
          Hydrochloric acid is an important inorganic chemical raw materials, widely used in chemical raw materials, dyes, medicine, food, printing and dyeing, leather, metallurgy and other industries.
