sodium hydroxide caustic soda

Sodium hydroxide caustic soda (chemical formula NaOH) is a highly corrosive inorganic alkali with irreplaceable applications in numerous fields such as chemical engineering, papermaking, textiles, metallurgy, and environmental protection. As a basic chemical raw material, sodium hydroxide caustic soda product quality and production capacity directly determine the production efficiency of downstream industries. Our sodium hydroxide caustic soda products, with their ultra-high purity, advanced production processes, and equipment advantages, have become the industry's preferred product.

The core advantage of our sodium hydroxide caustic soda products is first and foremost their ultra-high purity. Our sodium hydroxide caustic soda maintains a stable main content of ≥99.2%, far exceeding the requirements of the GB 209-2006 national standard. Impurities such as iron, chlorine, and sodium carbonate are all controlled below 0.005%. This high purity characteristic makes the sodium hydroxide caustic soda product stand out in high-end fields such as precision chemical synthesis and electronic-grade material preparation, effectively reducing side reactions, increasing the yield of target products, and lowering the cost of subsequent purification processes. Each batch of product undergoes multiple tests using precision equipment such as high-performance liquid chromatography and atomic absorption spectrometry to ensure unbiased purity indicators, providing customers with a stable and reliable raw material guarantee.

Behind this superior quality lies advanced production processes and equipment. We employ internationally leading ion-exchange membrane electrolysis technology, which offers significant advantages over traditional diaphragm methods, including lower energy consumption, less pollution, and higher product purity. The sodium hydroxide caustic soda production process incorporates a DCS automated control system, enabling precise control of the entire process from raw material feeding and electrolysis to product separation. Reaction parameter control accuracy reaches ±0.1℃, ensuring stable production conditions. Simultaneously, we are equipped with advanced equipment such as imported electrolytic cells, high-efficiency desalination devices, and continuous evaporation crystallization systems. The electrolytic cells utilize novel coated electrodes, increasing current efficiency to over 97%, while the desalination device removes calcium and magnesium ions from the raw brine to below 0.02 ppm, ensuring product purity and quality stability from the source.
