High Purity Sodium Hydroxide for Industrial Use

High Purity Sodium Hydroxide for Industrial Use

Product Attributes :

High-purity industrial sodium hydroxide ( $\text{NaOH}$ ) serves as a fundamental alkaline chemical widely recognized for its versatile industrial utility. Engineered through modern membrane cell electrolysis, our sodium hydroxide product ensures ultra-low impurity levels, rapid solubility, and powerful reactivity. Primary sodium hydroxide use spans across water treatment for precise pH adjustment and heavy metal precipitation, soap and detergent manufacturing through fat saponification, pulp and paper processing for wood lignin extraction, and alumina refining via the Bayer process. Available in versatile supply options including solid white flakes (≥ $\ge 99.0\%$ ), uniform micro-pearls, and pre-dissolved $50\%$ liquid solutions, this strong base offers exceptional reliability and performance for automated dosing systems and bulk chemical synthesis worldwide.

Product Description

Key Advantages & Operational Features

High Chemical Purity (≥ $\ge 99.0\%$ ): Manufactured utilizing advanced membrane cell technology, delivering exceptional assay levels with ultra-low iron and heavy metal impurities. This guarantees rapid reaction rates, minimizes unwanted side-reactions, and drastically limits sodium carbonate ( $\text{Na}_2\text{CO}_3$ ) contamination caused by atmospheric exposure.
Rapid & Complete Dissolution Rate: Engineered in uniform solid flakes or spherical pearls that dissolve rapidly and completely in water through an exothermic reaction. This ensures consistent alkalinity without leaving undissolved particulates, optimizing batch processing times and maximizing thermal mixing efficiency.
Multi-Industry Versatility: Formulated to fulfill stringent quality and performance standards across diverse industrial applications, including municipal wastewater neutralization, textile mercerization, pulp delignification, chemical synthesis, and high-potency Clean-in-Place (CIP) sanitation systems.

Major Industrial Uses & Applications
- Water & Wastewater Treatment: Used extensively in municipal and industrial wastewater facilities for pH adjustment, acid neutralization, and precipitating toxic heavy metals ( $\text{Fe}^{3+}$ , $\text{Cu}^{2+}$ , $\text{Pb}^{2+}$ +) from aqueous streams to meet strict environmental discharge standards.
- Soap & Detergent Manufacturing: Serves as the primary alkaline agent (lye) in saponifying fats, oils, and fatty acids to formulate commercial soap bases, heavy-duty industrial degreasers, household laundry detergents, and specialty surface cleaners.
- Pulp & Paper Processing: Key chemical reagent in the Kraft pulping process to dissolve unwanted lignin fibers from raw wood chips, break down cellulose material, and bleach paper pulp to achieve high brightness and strength.
- Alumina Refining & Metallurgy: Essential ingredient in the Bayer process, where it dissolves bauxite ore at high temperatures and pressures to extract refined alumina ( $\text{Al}_2\text{O}_3$ ), serving as the vital raw material for primary aluminum metal production.
- Textile & Chemical Synthesis: Widely applied for mercerizing cotton fabrics to improve tensile strength and luster, enhancing dye absorption, and acting as a base reactant to synthesize sodium salts, polycarbonate plastics, pharmaceutical intermediates, and CIP (Clean-in-Place) equipment sanitizers.
Packaging, Storage & Safety Profile
- Packaging Options: Available in 25kg woven PP bags with inner moisture-proof PE liners, 1000kg flexible jumbo super sacks for bulk handling, 250kg heavy-duty steel drums, or 1000L IBC totes designed for liquid chemical storage.
- Storage Requirements: Must be kept tightly sealed in a cool, dry, and well-ventilated warehouse. Store strictly away from strong acids, ambient moisture, carbon dioxide, and reactive metals (such as aluminum, zinc, and tin) to prevent exothermic reactions.
- Hazard Class: Categorized as Class 8 Corrosive Substance (UN 1823 for solid flakes/pearls; UN 1824 for liquid solutions). Always wear full personal protective equipment (PPE), including chemical splash goggles, neoprene gloves, alkali-resistant aprons, and full-face shields during transfer and handling operations.
