Technical Specifications 

• Key Features, Primary Applications & Handling Guidelines for High-Purity Solid Sodium Hydroxide (NaOH)

  High-purity solid Sodium Hydroxide (NaOH), produced via advanced membrane electrolysis technology, is a foundational alkaline reagent engineered to deliver peak chemical performance across high-precision and heavy industrial manufacturing.

  Key Features & Benefits

  • High Chemical Purity Standards: Manufactured using modern membrane cell electrolysis, achieving an active purity level of up to 99%. This process ensures exceptionally low trace iron (Fe), sodium chloride (NaCl), and heavy metal impurities, preventing unintended side reactions in delicate synthesis pathways.

  • Rapid Solubility & High Reactivity: Exhibits excellent water solubility, dissolving rapidly to generate substantial exothermic heat and form a strongly basic solution for immediate industrial processing.

  • Full UN 1823 Regulatory Compliance: Certified under UN 1823 dangerous goods specifications, adhering strictly to International Maritime Dangerous Goods (IMDG) and International Air Transport Association (IATA) codes.

  • Moisture-Proof Packaging Protection: Packed in heavy-duty, UN-approved moisture-barrier packaging to prevent atmospheric carbon dioxide absorption (CO2) and deliquescence during extended maritime transit.

  Primary Industrial Applications

  • Water Treatment & pH Regulation: Serves as a primary base for rapid pH neutralization of acidic industrial effluent, municipal water treatment, and heavy metal ion precipitation.

  • Soaps & Detergents Manufacturing: Functions as the indispensable saponification agent, converting triglycerides into hard soap bars, commercial surfactants, and heavy-duty degreasers.

  • Textile & Dyeing Operations: Essential for cotton fabric mercerization, raw fiber scouring, and synthetic textile processing to improve tensile strength and dye receptivity.

  • Pulp & Paper Processing: Facilitates wood chip delignification during the Kraft pulping process, pulp bleaching, and fiber de-inking in recycling mills.

  • Chemical Synthesis & Metallurgical Refining: Acts as a vital chemical building block for manufacturing sodium salts, polycarbonates, organic intermediates, and extracting alumina from bauxite via the Bayer process.

  Packaging & Shipping Logistics

  • Standard Packaging Options: Supplied in heavy-duty 25kg PP/PE woven bags fitted with thick inner polyethylene (PE) liners, or durable 200kg UN-certified steel drums.

  • Palletizing Standards: Loaded at 1.0 to 1.2 metric tons per wooden/plastic pallet, fully secured with UV-resistant stretch wrapping for maximum stability.

  • Transport Classification: Shipped as a Class 8 Corrosive Solid (UN 1823), fully backed by complete Safety Data Sheets (SDS) and Dangerous Goods (DG) shipping certificates.

  Storage & Safety Handling Guidelines

  • Storage Environment: Store in a cool, dry, well-ventilated warehouse facility isolated from strong acids, moisture, and reactive light metals (such as aluminum, zinc, and tin).

  • Atmospheric Protection: Maintain tightly sealed packaging at all times; solid NaOH is highly hygroscopic and rapidly absorbs atmospheric moisture and carbon dioxide (CO2), leading to surface caking.

  • Personal Protective Equipment (PPE): Due to its strongly corrosive nature, operators must wear complete safety gear, including chemical splash goggles, full face shields, heavy-duty rubber/nitrile gloves, and chemical-resistant protective clothing.
