Quality index
Performance characteristics
1. It is easy to use and can be mixed with water in any proportion. It is suitable for automatic continuous addition measurement.
2. It has good acid resistance and excellent whitening effect even at low pH value.
3. This product adopts advanced nanofiltration technology, which makes it has low salt content and good storage stability at room temperature.
4.Compared with similar products, it has considerable light fastness and acid and alkali fastness
5. The product remains stable above 0 ℃ and may freeze below - 3 ℃. However, it will dissolve after heating, which does not affect the use effect.
Scope of application
1. Fluorescent whitening is carried out in pulp.
2. Fluorescent whitening is carried out in surface sizing.
3. Fluorescent whitening is carried out during coating.
instructions
1. Can be directly added in the pulp, conventional dosage: 0.05-1.2% (absolute dry pulp).
2. In the surface sizing, better whitening effect can be obtained by using starch, CMC and PVA in common use. The conventional dosage is 0.5-10 g / L.
3. In the coating process, any position can be added, when PVA, CMC and starch are used together, the better effect will be obtained. The conventional dosage: 0.1-1.4% (for coating weight).
Packaging and storage
25kg, 50kg, 200kg, 1100kg or plastic drum packaging, according to customer needs can provide special packaging.
It should be stored in a cool, dry and ventilated warehouse.
