Application
Jiangsu Zehui Magnesium Base has been deeply engaged in magnesium compounds for more than 20 years, has independent import and export rights, and has passed ISO9001 international quality certification system, with stable quality and customizable indexes to meet the demand for high-performance materials in different industries. Especially in the application of magnesium hydroxide has made remarkable achievements, especially in the application of pH adjustment, and its success is mainly attributed to the in-depth understanding of the characteristics of magnesium hydroxide and innovative applications.
Wastewater treatment
Acidic Wastewater Neutralization: Magnesium hydroxide is widely used to neutralize acidic wastewaters such as sulfuric and nitric acids from acid rain. By releasing hydroxide ions (OH-), it combines with hydrogen ions (H⁺) in the wastewater to form water, thus reducing the acidity of the wastewater to meet the discharge standard or make it more suitable for subsequent treatment. Precipitation of heavy metal ions: In the process of wastewater treatment, magnesium hydroxide can also react chemically with heavy metal ions (e.g., lead, cadmium, mercury, etc.) in wastewater to form insoluble precipitates. These precipitates can be removed from the wastewater by filtration or precipitation process, effectively reducing the pollution of heavy metals to the environment.
Pharmaceuticals
Antacids: In the pharmaceutical industry, magnesium hydroxide is used as an antacid ingredient to treat stomach pain and heartburn caused by excessive stomach acid. Its weak alkalinity can neutralize stomach acid and regulate the pH of gastric juice, thus relieving stomach discomfort.
Textile Industry Dyeing pH Adjustment: In the textile dyeing process, specific dyes need to be in a specific pH range to achieve optimal dyeing results. Magnesium hydroxide can be used to regulate the pH of the treatment solution to ensure that the dyestuffs are fully dissolved and adsorbed uniformly onto the fibers to achieve the desired color and color fastness.
Agricultural sector
Soil improvement: magnesium hydroxide can also be used for soil improvement, adjusting the pH value of the soil. In acidic soil, moderate addition of magnesium hydroxide can raise the pH value of the soil, improve the soil structure, and promote the growth and development of plants.
