◆ Performance and characteristics

1. The product is a stilbene triazine derivative, which is a tetrasulfonic acid liquid brightener.

2. It is anionic, resistant to pH: 6-11, resistant to hard water to 300ppm, resistant to free chlorine to 0.25%, not resistant to copper.

3. Color light: with blue-violet light fluorescence.

4. It has good storage stability.

5. Although liquid fluorescent whitening agent has a good whitening effect, it should not be used in excess, otherwise it will be counterproductive.

◆ Scope of application

It is suitable for and whitening paper pulp slurry during surface sizing and coating, with the best surface sizing and coating effect.

◆ Application method

1. Pulping process: When performing fluorescent whitening in the pulp, ABJ-L should be added before alum or cationic additives, and it is not suitable to use them at the same time. Suitable for PH value 4.0-10, reference dosage: 0.05-1.4% (absolute dry pulp).

2. Surface sizing process: It can be used together with commonly used starch, CMC, PVC and anionic and weakly cationic synthetic sizing agents to achieve better whitening effects. Reference dosage: 0.5g/L-12g/L.

3. Pigment coating process: it can be formulated in solution form at any stage of coating preparation. Suitable for PH value 6.0-11. Reference dosage: 0.15-1.4% (to the weight of the paint) It is better to use PVA, CMC and starch at the same time.

◆ Packaging and storage

Packed in 25 kg or 200 kg plastic drums, it can be packed according to customer requirements. stored in a cool, dry place away from light, and avoid contact with cationic compounds (such as aluminum sulfate, cationic resin, etc.). The validity period is 6 months.
