1. High Purity and Low Impurities
Sodium Hydroxide Flakes utilizes a mature ion-exchange membrane electrolysis refining process, deeply removing various impurities. The sodium hydroxide content is consistently maintained above 99.0%, effectively avoiding the generation of production byproducts and improving overall production efficiency.
2. Uniform Form and Easy Use
The uniform flake form prevents clumping and facilitates convenient metering. Whether added in small batches or used in large-scale industrial applications, the dosage can be accurately controlled without additional crushing, saving labor costs.
3. Rapid Dissolution and Thorough Reaction
Sodium Hydroxide Flakes are readily soluble in water and glycerol, dissolving rapidly with significant exothermic reaction. Their alkaline effect is quickly activated, making them suitable for various chemical reaction conditions.
4. Stable Supply and Customization Support
As a source manufacturer, we have large-scale production lines and maintain ample inventory, supporting small-batch sample orders and long-term large-volume purchases. We can also adjust product purity and flake specifications according to customer needs.
1. Chemical Manufacturing
As a core basic raw material, it is used in the production of sodium salts, detergents, bleaching agents, dyes, pharmaceutical intermediates, etc., and is an indispensable raw material in chemical production.
2. Textile Industry
Used for desizing, scouring, and mercerizing cotton and chemical fibers, removing surface impurities, improving fabric luster and dye adhesion, and making dyeing more uniform and durable.
3. Water Treatment
Adjusting wastewater pH, neutralizing acidic wastewater, removing heavy metal ions and impurities from water bodies, purifying water quality, suitable for industrial wastewater and municipal sewage treatment scenarios.
4. Pulp and Paper Making
Used in wood cooking and pulp bleaching, effectively decomposing lignin, improving pulp purity and toughness, and optimizing paper quality.
5. Metal Processing
Used for rust and oil removal on metal surfaces, pretreatment before electroplating and spraying, improving metal surface smoothness and coating adhesion.
6. Other Fields
Widely used in leather tanning, food processing, petroleum refining, electroplating, and other industries as an auxiliary raw material.
A large textile manufacturing company in Jiangsu Province urgently needed high-purity sodium hydroxide flakes for the mercerizing process of pure cotton fabrics to improve fabric gloss and dyeing effect.
Shandong Aolansu customized and supplied 99.2% high-purity flake sodium hydroxide, strictly controlling the content of impurities such as ferric oxide.
Results: Fabric gloss increased by 15%, dye usage was reduced by 10%, and dyeing uniformity was significantly improved; the two parties have reached a two-year stable supply cooperation agreement, and the quality of product batches has remained consistent.
1. Hazardous Material Properties: Sodium Hydroxide Flakes are classified as Class 8 corrosive hazardous materials, exhibiting strong hygroscopicity and corrosiveness.
2. Protective Requirements: During handling, alkali-resistant protective clothing, goggles, rubber gloves, and a protective mask must be worn. Avoid direct skin and eye contact and prevent inhalation of dust and vapors.
3. Emergency Treatment: In case of accidental contact with skin or eyes, immediately flush with plenty of running water for at least 15 minutes. Seek medical attention immediately if the condition is severe. In case of inhalation, immediately move to fresh air and seek medical attention if discomfort persists.
4. Waste Disposal: Indiscriminate dumping of waste materials is strictly prohibited. Disposal must be carried out in strict accordance with hazardous chemical waste standards to prevent soil and water pollution.
5. Supporting Documents: The company can provide a complete Safety Data Sheet (SDS), detailing operating procedures, storage requirements, and emergency response plans to ensure safe and standardized use by customers.
Q1: What are the key differences between your company's Sodium Hydroxide Flakes and ordinary low-purity products?
A1: We use a professional ion-exchange membrane electrolysis process to produce our products, ensuring a stable purity of ≥99.0%. We strictly control the content of impurities such as sodium carbonate, sodium chloride, and iron oxide. Compared to low-purity caustic soda flakes (96%-98%), this reduces production side reactions, improves the quality of the final product, and reduces equipment corrosion and wear, making it suitable for high-end industrial production needs.
Q2: Do you support small-batch sample purchases, and can you customize packaging specifications afterwards?
A2: Yes. We can accept small-batch trial orders of 1-5 tons to facilitate customers' quality testing. We also provide customized packaging such as 25kg bags and 50kg drums. Orders are fully trackable, allowing you to monitor the shipment status at any time.
Q3: How do you ensure consistent quality across every batch?
A3: Our company implements full-process quality control management, with strict testing at every stage from raw material selection and production to finished product delivery. Each batch of products comes with a quality inspection report (CoA). Relying on a standardized factory production system and strict adherence to industry production standards, we ensure consistent quality between batches, making us suitable for long-term, stable procurement.
Shandong Aolansu Environmental Protection Technology Co., Ltd. is a professional chemical raw material manufacturer and a high-quality supplier based in China. Leveraging the advantages of its own factory production, we strictly control product quality, focusing on customer needs and providing high-quality, cost-effective supplies along with professional supporting services. Whether it's an initial sample purchase or a long-term strategic partnership, we can provide comprehensive support for our clients, making us a trustworthy partner for flaky sodium hydroxide procurement.
