1. High Concentration and Excellent Purity
Utilizing ion-exchange membrane electrolysis, the sodium hydroxide content is stably controlled at 45% ± 0.5%, with strict control over various impurities. It meets the requirements of high-end production conditions and is suitable for conventional industrial applications.
2. Ultra-Stable Performance
Its alkalinity is far superior to low-concentration products, resulting in rapid and thorough neutralization and saponification reactions. It is not easily deteriorated during long-term storage, and the quality remains highly consistent across batches, ensuring no impact on normal production line operations.
3. Time-saving, labor-saving, and energy-efficient
Ready to use immediately after opening the container, requiring no secondary dilution, significantly reducing manual operation time and effectively improving enterprise production and operational efficiency.
4. Stable supply and customization support
Our own factory ensures large-scale production, providing a stable supply for both small-batch sample orders and large-volume bulk purchases. We also offer customized packaging and technical guidance based on industry-specific needs.
1. Pulp and paper industry: Used in wood cooking and pulp bleaching, effectively removing lignin, resulting in purer, stronger pulp and higher-quality finished paper.
2. Textile industry: An essential raw material for desizing, refining, and mercerizing cotton fabrics, enhancing fabric gloss, making dyeing more uniform, and improving color fastness.
3. Water treatment: Adjusts wastewater pH, neutralizes acidic wastewater, and removes heavy metal ions from water; suitable for industrial wastewater and municipal sewage purification.
4. Chemical manufacturing industry: Used as a basic raw material in the production of sodium salts, detergents, dyes, and pharmaceutical intermediates, with wide and flexible applications.
5. Petroleum Industry: Used in oil refining processes for desulfurization and deacidification, improving the quality of petroleum products and reducing impurity content.
6. Other Fields: Commonly used as an auxiliary chemical raw material in industries such as metal surface treatment, electroplating, leather tanning, and food processing.
Case Study: Wastewater Treatment Project at a Chemical Plant in Jiangsu Province
A fine chemical company in Jiangsu Province generates a large amount of acidic wastewater during its production process. The wastewater pH value is consistently maintained at 3.0–3.5, and it contains excessive levels of heavy metal ions, failing to meet discharge standards. In 2024, the company partnered with Shandong Aolansu to switch to using our 45% sodium hydroxide solution for wastewater treatment.
- Application Solution: Our technical team provided on-site process guidance and optimized the dosing ratio parameters; using 45% high-purity liquid alkali, the wastewater pH was directly adjusted to 6.8–7.5, while simultaneously precipitating and removing heavy metal ions, achieving a heavy metal removal rate of over 98%.
1. Wastewater consistently meets national discharge standards, mitigating environmental penalties.
2. No secondary dilution required, reducing labor costs by 30% and wastewater treatment time by 25%.
3. Stable batch quality ensures continuous and normal production for enterprises.
This case fully demonstrates the reliability of this product under complex industrial conditions and reflects our company's strength as a professional supplier in providing customized solutions.

Q1: What are the main differences between 45% sodium hydroxide solution and 32% liquid alkali?
A1: 45% liquid alkali has a higher concentration and purity, fewer impurities, stronger alkalinity and reaction efficiency, requires no secondary dilution, saves time and labor, and is suitable for high-requirement industrial production; 32% liquid alkali is more suitable for low-concentration, cost-sensitive, and routine simple working conditions.
Q2: How is the quality of 45% sodium hydroxide solution guaranteed during long-distance transportation?
A2: The product uses sealed, corrosion-resistant packaging to prevent leakage and contamination; it strictly adheres to Class 8 corrosive substance transportation standards, cooperates with professional hazardous chemical logistics companies, and avoids exposure to sunlight and impact throughout the journey; each batch of products comes with a quality inspection report, and after-sales quality tracking services are provided.
Q3: Can 45% sodium hydroxide solution be customized for special industry needs?
A3: Yes. Leveraging our own factory's R&D and production capabilities, we can customize and adjust impurity levels (such as electronic-grade low-iron specifications), provide food-grade packaging, and offer exclusive process technology guidance for industries such as textiles, water treatment, and fine chemicals to meet special production requirements.
