Key Product Advantages
High Purity & Low Impurity: Qingfeng 98% caustic soda flakes maintain stable 98% minimum sodium hydroxide content with strictly controlled carbonate, chloride and iron ion impurities. Low impurity composition effectively avoids secondary pollution and reaction failure, ensuring high-standard industrial production results.
Fast Dissolution & High Alkalinity: Uniform flake structure features rapid water solubility with no residue. It quickly forms high-concentration alkaline solution, providing efficient acid neutralization, pH adjustment and degreasing capabilities, greatly improving industrial processing efficiency.
Stable Industrial Performance: Consistent batch-to-batch quality ensures stable alkalinity and chemical activity. Qingfeng 98% NaOH flakes perform steadily in continuous industrial production, reducing formula adjustment frequency and lowering production defective rates.
Wide Adaptability & Cost-Effective: Suitable for most medium and high-standard industrial alkaline scenarios. Balanced purity and cost make it the optimal choice for mass industrial procurement, meeting production demands while controlling overall raw material costs.
Export-Grade Sealed Packaging: Adopts 25kg double-layer moisture-proof and airtight packaging. Effectively isolates air moisture to prevent deliquescence and caking during long-distance sea freight and storage. Custom shipping marks are available for global export orders.
Wide Industrial Applications
Water Treatment Industry: Used for industrial wastewater pH adjustment, acid sewage neutralization, heavy metal removal and water quality purification, improving sewage treatment efficiency.
Textile & Dyeing Industry: Applied for cotton fabric mercerization, dyeing auxiliary and textile degreasing, enhancing fabric toughness and color fixation effect.

FAQ
1. What is Qingfeng 98% caustic soda flakes used for?
Qingfeng 98% caustic soda flakes (NaOH) are high-purity industrial alkaline chemicals, widely used for industrial water treatment pH adjustment, textile mercerization and dyeing, papermaking pulping, chemical synthesis, petroleum deacidification and equipment cleaning, covering most industrial alkaline processing scenarios.
2. What is the difference between 98% and 99% caustic soda flakes?
98% caustic soda is the mainstream industrial grade with qualified low impurity indicators, suitable for most conventional industrial production. 99% high-purity grade is applied for ultra-high-precision chemical synthesis and high-end fine chemical projects. 98% Qingfeng caustic soda features higher cost performance and stable performance for mass industrial use.
3. Does 98% caustic soda easy deliquesce?
Yes. Caustic soda flakes have strong deliquescence. Qingfeng products adopt enhanced sealed moisture-proof packaging. As long as stored in dry and sealed environment, it can effectively avoid caking and quality deterioration during storage and transportation.
4. What is your packaging standard for Qingfeng caustic soda?
Standard 25kg/bag double-layer sealed moisture-proof woven bag, anti-leakage and anti-deliquescence, suitable for global sea freight and long-distance transportation. Custom shipping marks and OEM packaging are available for large bulk orders.
5. Can you provide quality inspection documents?
Yes. Every batch of Qingfeng 98% caustic soda flakes is strictly tested before delivery. We can provide official Certificate of Analysis (COA), batch inspection reports and complete qualification documents for customer quality inspection and customs clearance.
6. What safety precautions are needed for caustic soda operation?
Operators must wear protective gloves, goggles and protective clothing. Avoid direct skin and eye contact. Dissolve slowly in water and stir continuously. Store separately from acidic chemicals to prevent chemical reactions.
