Technical Specifications

Structure

Core Advantages:

1. High Purity and Low Impurities

30% Caustic Soda Solution is refined using an ion-exchange membrane electrolysis process, effectively removing various organic and inorganic impurities; the sodium hydroxide content is stably controlled at 30%±0.5%, with extremely low levels of heavy metals and salt impurities, meeting the stringent standards of high-end industrial production.

2. Stable Performance and Consistent Quality

Possesses long-lasting strong alkalinity, offering excellent neutralization and saponification effects; it is not easily deteriorated during storage and transportation, with minimal batch-to-batch quality variations, ensuring continuous and stable production for enterprises.

3. Ready to Use, Improved Efficiency

30% Caustic Soda Solution requires no secondary dilution and can be directly used in production, simplifying operations, saving labor costs, and significantly improving enterprise production efficiency.

4. Ample Supply and Customization Support

The company has a large-scale production base, capable of handling large-volume orders and long-term cooperative supply; it supports customer customization of different concentrations from 20% to 50%, and custom packaging specifications are available upon request.

Real-World Application Cases:

Case 1: Paper Industry – High-Toughness Pulp Production

A large paper mill in Zhejiang previously faced problems with low pulp purity, high lignin residue, and substandard paper toughness and whiteness. After switching to Shandong Aolansu 30% Caustic Soda Solution for wood cooking and pulp bleaching:

1. Lignin removal rate increased by 18%;

2. Pulp brightness increased from 78% to 89%;

3. Paper tensile strength increased by 25%, and production waste loss decreased by 12%;

4. The product's low impurity characteristics effectively extended the paper's shelf life.

Case 2: Textile Industry – Mercerizing and Dyeing Finishing

A cotton textile company in Jiangsu Province had long faced problems with uneven fabric gloss, poor dye adhesion, and high rework rates due to color differences in its fabric mercerizing process. After using this product at a suitable concentration of 28%-30% for mercerizing:

1. Fabric gloss increased by 30%;

2. Dye adsorption rate increased by 22%, effectively saving dye costs;

3. Batch-to-batch color consistency reached 98%, completely solving the dyeing rework problem;

4. Extremely low iron content prevented fabric yellowing, significantly upgrading the quality of the finished product.

Main Application Areas

30% Caustic Soda Solution, as a general-purpose basic chemical raw material, covers core applications in multiple industries:

1. Paper and Pulping: Wood cooking, lignin removal, pulp bleaching, improving pulp purity and toughness.
