Relying on the strong R&D and manufacturing capabilities of Guolin Technology, after more than a decade of efforts, we have overcome multiple technological challenges such as oxygen production, ozone, oxidation, distillation, and granulation. We have mastered the core technology and specialized equipment manufacturing technology of the "ozone oxidation maleic anhydride process" for producing crystalline glyoxalic acid. By utilizing exhaust gas recovery technology and wastewater reuse technology, the manufacturing cost of the product has been reduced. The three wastes are discharged less during the production process, and the product does not contain carcinogens such as glyoxal. It is a non hazardous chemical product that is safe and convenient for storage and transportation. It is widely used in industries such as medicine, cosmetics, spices, agriculture, chemical industry, water treatment agents, petroleum, cement, leather, printing and dyeing.
