Fluorescent whitening agent BA (2-sulfonic acid)

Optical brightener BA (2-sulfonic acid) is a specialized chemical agent widely used in the paper industry. This product plays a vital role in improving the whiteness and brightness of paper products. Its unique chemical structure allows it to absorb UV rays and re-emit visible blue light, thus counteracting the yellowish tint of natural paper fibers and making the paper appear whiter and brighter.

Product application:
1. In-pulp whitening:
The optical brightener BA (2-sulfonic acid) has good affinity with paper fibers and is ideal for in-pulp whitening. By adding whiteners directly to the pulp, manufacturers can achieve uniform whiteness throughout the paper.
2. Surface sizing:
This whitening agent can be used for surface sizing, which is sizing on the surface of paper to increase whiteness. It can be used in combination with various sizing agents such as CMC (carboxymethylcellulose), PVA (polyvinyl alcohol) and starch.
3. Coating process:
The optical brightener BA (2-sulfonic acid) is also suitable for coating processes. It can be mixed into coating formulations at the stage to provide additional whiteness to paper products.

Product advantages:
1. Good affinity with paper fibers
- Uniform whitening: The affinity of the whitening agent to the paper fibers ensures that the whitening effect is evenly distributed, giving the paper a consistent appearance.
- Effective in pulp: Its strong adhesion to paper fibers makes it particularly effective in paper pulp, providing a long-lasting whitening effect.
2.Easy to use
- Water Solubility: The optical brightener BA (2-sulfonic acid) is water soluble, which simplifies its application. It dissolves easily in water and can be used directly in various processes.
- Direct dilution: This product can be diluted directly with water for direct use in the production process.
3. Chemical stability
- Alkali resistance: This whitening agent has good alkali resistance and can function stably and effectively in various papermaking processes.
- Peroxide Stability: It remains stable in the presence of peroxides and perborate, ensuring its effectiveness during the bleaching stage of paper production.

Features:
1. Highly effective whitening agent
- High whitening power: Fluorescent brightener BA (2-sulfonic acid) is a powerful whitening agent that can significantly improve the brightness of paper and textiles.
- Stable results: Its stable performance ensures a consistent appearance for every batch of paper or fabric treated with the whitener.
2.Easy to use
- Soluble in water: This product is easily soluble in water and can be easily integrated into various production processes without complicated preparation processes.
- Easy to use: It can be diluted directly with water and added to the production line, which is a convenient option for manufacturers.
3. Chemical compatibility
- Alkali resistance: The optical brightener BA (2-sulfonic acid) remains stable and effective under alkaline conditions common in the paper industry.
- Stable against peroxides: The stability of optical brighteners in peroxides ensures that they remain effective during the bleaching process, thus providing reliable whitening results. ,

Instructions for use:
1. Paper industry
- Dissolution method: Dissolve the optical brightener BA (2-sulfonic acid) in 20 times the volume of water and then add it to the pulp, surface sizing or coating formula.
- Dosage: For pulp whitening, the recommended dosage is 0.1-0.8% of the dry weight of the paper. For surface sizing, the dosage range is 1-10 g/l. For coating applications, the recommended reference dosage is 0.1-0.75%.
2. Textile industry
- Fabric whitening: Dissolve the fluorescent whitening agent BA (2-sulfonic acid) in water and add it directly to the dye bath. The recommended dosage is 0.08-0.3% and the liquor ratio is 1:20-40.
-Using temperature: Suitable temperature is 60-100°C to ensure effective whitening of fabrics.
