Sodium Sulphate Na2SO4 1000 KG / BAG Used in the Papermaking
Sodium sulfate, chemically known as anhydrous sodium sulfate (Na₂SO₄), is a white or slightly yellow crystalline powder with good solubility, strong stability, and non-toxicity. As a basic inorganic chemical raw material, sodium sulfate is widely used in textile, glass, papermaking, detergent and other industries. In the papermaking industry, sodium sulfate plays an important role due to its unique chemical properties and diverse application advantages.

1. Cost advantage:
Sodium sulfate is rich in resources and relatively cheap. Compared with other chemical additives, it can effectively reduce the production costs of papermaking enterprises, especially in large-scale production, showing significant economic advantages.
2. Environmentally friendly features:
Sodium sulfate is a non-toxic and harmless chemical substance that meets the requirements of modern papermaking industry for green environmental protection. In the process of pulping and paper production, Sodium sulfate does not produce harmful by-products, which helps enterprises achieve clean production.
3. Convenient usage:
Sodium sulfate has good water solubility and stability, is easy to disperse in pulp, will not affect other chemical components of pulp, and will not cause corrosion to equipment, making it easy to control and implement the production process.
1. In large papermaking enterprises at home and abroad, the application of sodium sulfate is very common. Large-scale packaging paper production: When some papermaking companies produce high-strength packaging paper, they add sodium sulfate to the pulp to increase the compressive strength of the paper, thus meeting the demand for durability of cartons in logistics and transportation.
2. Production of high-end printing paper: Some high-end printing companies, especially those producing paper for publishing albums and books, have improved the whiteness and printing quality of paper by adding sodium sulphate, thus meeting customers' requirements for high-quality paper.
As the paper industry's demand for environmental protection and high-quality production continues to increase, the application prospects of sodium sulfate will be broader.
