caustic soda pearls sodium hydroxide price online

Sodium hydroxide (also known as caustic soda pearls) is a key basic chemical raw material in the industrial field, widely used in papermaking, textile printing and dyeing, water treatment, and daily chemical soap making. Caustic soda pearls price is affected by raw materials (salt, electricity) and market supply and demand, but is even more closely related to the product manufacturing process, particle uniformity, and delivery stability. These three core indicators directly determine the differences in the product's cost-effectiveness.

The caustic soda pearls price production process is the fundamental factor affecting the quality and price of sodium hydroxide. High-quality sodium hydroxide uses an advanced membrane electrolysis process. First, refined brine (sodium chloride solution) is fed into a membrane electrolysis cell for electrolysis to generate a high-purity sodium hydroxide solution. Then, the solution is transported to a dedicated spray granulation tower, where it is atomized into tiny droplets through high-pressure nozzles. These droplets come into full contact with dry, hot air at 300-350℃ inside the tower, rapidly evaporating moisture and ultimately forming spherical bead-like particles. Compared to traditional mercury electrolysis or diaphragm electrolysis, membrane electrolysis can achieve a purity of over 99% for caustic soda pearls, with extremely low impurity content (such as chloride and iron), while reducing energy consumption by 15%-20%. This ensures product quality stability and provides a cost basis for reasonable pricing.

Particle size uniformity is a core quality indicator for caustic soda pearls price and a crucial basis for price stratification. High-quality caustic soda pearls price particles have a diameter concentrated in the 0.6-1.0 mm range, with over 95% of particles having a size deviation of no more than 0.3 mm. This precision relies on precise control of nozzle pressure (3-5 bar), hot air flow rate, and the temperature field within the granulation tower during production. Uniform caustic soda pearls price particles dissolve more slowly during use, avoiding equipment corrosion caused by excessively high local concentrations; caustic soda pearls price is less prone to clumping during storage and transportation, reducing losses; and they ensure accurate metering during industrial batching, reducing downstream production errors. Typically, caustic soda pearls price with compliant particle uniformity is 5%-10% more expensive than ordinary products, but the resulting production stability helps customers reduce overall costs.

Delivery stability affects price certainty in long-term cooperation. Reliable suppliers ensure stable annual production capacity by operating multiple parallel production lines (equipped with 2-3 spray granulation lines) and stockpiling 1-2 months' worth of raw materials. Even during peak demand seasons in the textile and water treatment industries (Q3-Q4), they can deliver within 7-14 days after order confirmation. In contrast, suppliers with unstable delivery rates often experience temporary price increases or supply disruptions due to capacity fluctuations, causing production halts for customers. For bulk purchasing customers, stable delivery not only locks in long-term contract prices but also mitigates the risk of short-term market price fluctuations.
