caustic soda pearls sodium hydroxide 99

Caustic soda pearls 99 are representative of high-purity basic chemical raw materials in the industrial sector. Caustic soda pearls 99 are widely used in industries with stringent purity requirements, such as precision chemical synthesis, pharmaceutical intermediate manufacturing, high-end textile printing and dyeing, and electronic-grade water treatment. Their core competitiveness lies not only in the efficiency advantages brought by their high purity but also in their leading production technology and advanced equipment, ultimately achieving extremely low impurity content, making them a preferred raw material for downstream high-value-added industries.

High purity is the core characteristic of Caustic soda pearls 99 and the key difference between them and ordinary Caustic Soda Pearls. The effective sodium hydroxide content of the product is consistently maintained above 99%, far exceeding the 96%-98% content standard of ordinary industrial-grade Caustic Soda Pearls 99. This high purity means that in industrial applications, each unit weight of the product can exert a stronger alkaline effect, reducing the amount of raw materials used by approximately 1%-3%. This reduces transportation and storage costs as well as the consumption of auxiliary materials in subsequent neutralization reactions, directly supporting downstream enterprises in improving production efficiency and controlling costs.

The level of caustic soda pearls 99 production technology determines the upper limit of the product's purity. Sodium hydroxide 99% solution utilizes internationally leading ion-exchange membrane electrolysis technology. The refined brine undergoes deep purification (removing impurities such as calcium, magnesium, and sulfate to the ppm level) before being fed into an imported ion-exchange membrane electrolyzer for electrolysis. During electrolysis, the ion-exchange membrane precisely blocks the migration of chloride ions and other impurity ions, ensuring the purity of the resulting sodium hydroxide solution reaches over 99.5%. Subsequent processes include multi-effect evaporation concentration and precision spray granulation, achieving closed-loop production control throughout the entire process, guaranteeing high content and low impurities from the technological source.

Advanced equipment forms the hardware foundation for stable production. The caustic soda pearls 99 production line is equipped with a German-imported multi-effect evaporation system, a Swiss high-precision spray granulation tower, and online purity monitoring instruments. The nozzle precision of the spray granulation tower is controlled at the 0.01mm level, ensuring uniform atomized droplets. The online monitoring instruments analyze product purity every 30 seconds, with data fed back to the central control system in real time for dynamic adjustment of production parameters. Furthermore, the entire set of equipment is constructed of 316L stainless steel to prevent corrosion and the introduction of impurities during production, ensuring product quality stability.

The extremely low impurity content is a significant advantage of caustic soda pearls 99. The product contains ≤0.03% chloride, ≤0.001% iron, and ≤0.0005% heavy metals, far below the standards for ordinary beaded soda. This low impurity characteristic effectively avoids quality defects in downstream products (such as pharmaceutical intermediates and electronic-grade chemicals) caused by excessive impurities, reduces equipment corrosion and wear, and is particularly suitable for precision manufacturing scenarios with stringent requirements for raw material purity.
