Compared with products with ordinary concentration, our 45% Sodium Hydroxide Solution has obvious advantages and is more convenient to use. 1. High concentration and purity: It still adopts ion-exchange membrane electrolysis technology, which can filter out all impurities. The sodium hydroxide content is stably maintained at 45%±0.5%, which can meet both high-demand production scenarios and regular use; 2. Super stable performance: Its strong alkalinity is more prominent than that of low-concentration products, the neutralization and saponification reactions are fast and thorough, it is not easy to deteriorate after long-term storage, and the quality of each batch is almost the same, so there is no need to worry about affecting production; 3. Labor-saving and efficient: No secondary dilution is needed, it can be used directly after opening, which can save a lot of operation time and improve work efficiency; 4. Stable supply: Shandong Aolansu produces it in its own factory with a large scale. Whether you need small-batch trial orders or large-batch procurement, we can provide stable supply, and long-term cooperation is completely no problem.

Because of its high concentration and stable performance, this product has a wide range of application scenarios and is used in many industries.

1. Pulp and Paper Industry: It is used for cooking wood and bleaching pulp, which can easily remove lignin, make the pulp purer and more tough, and the paper produced is of better quality;

2. Textile Industry: It is indispensable for desizing, scouring and mercerizing of cotton fabrics, which can make the fabrics more shiny, and the dyeing can be more uniform and firm;

3. Water Treatment Field: It can adjust the pH value of wastewater, neutralize acidic wastewater, and remove heavy metal ions in water to help purify water quality, which can be used for both industrial wastewater and municipal sewage;

4. Chemical Manufacturing: As a basic raw material, it can be used to produce sodium salts, detergents, dyes and pharmaceutical intermediates, with very flexible uses;

5. Petroleum Industry: During petroleum refining, it is used for desulfurization and deacidification, which can improve the quality of petroleum products and reduce impurities;

6. Other Fields: Industries such as metal surface treatment, electroplating, leather tanning and food processing also often use it as an auxiliary raw material. As a manufacturer in China, Shandong Aolansu can also provide suitable products and simple technical guidance according to the specific needs of your industry.

We are very flexible in terms of packaging. The conventional ones are 25kg plastic drums, 200kg iron drums and 1000kg IBC totes. If you have special procurement needs, we can also customize the packaging size. When storing, please note that it should be sealed and placed in a cool, dry and well-ventilated warehouse, avoiding direct sunlight, and not placed together with acidic substances and flammables to prevent moisture absorption and deterioration. During transportation, it should be noted that it belongs to Class 8 corrosive goods, and it must be transported by vehicles with hazardous chemicals transportation qualifications, avoiding collision and leakage, and taking protective measures throughout the process. As a reliable supplier in China, Shandong Aolansu can also help you arrange logistics to ensure that the products are safely delivered to you.

Let’s talk about the safety precautions here. After all, it is a corrosive product, so you must operate it carefully. It belongs to Class 8 corrosive goods with strong corrosiveness. Never let it come into direct contact with your skin or eyes, otherwise it will cause severe burns. When operating, you must wear alkali-resistant protective clothing, safety goggles and rubber gloves, and do not inhale its steam. If you accidentally touch it, quickly rinse it with a large amount of flowing water for at least 15 minutes, and go to the hospital in time if the situation is serious. Waste disposal should not be sloppy. It must be disposed of in accordance with the hazardous chemicals waste standards and cannot be dumped at will, otherwise it will pollute the environment. As a professional factory, Shandong Aolansu will provide a complete Safety Data Sheet (SDS) to help you operate and use it correctly and safely.
