First, the physical and chemical properties:
This product is a pale yellow uniform powder, slightly purple color pure light, can be dissolved more than 80 times the amount of water softeners are anionic, acid and alkali the extent to PH6 11, the amount of suitable PH8 dye dissolved. Resistant to hard water to 300PPM swim ion resistance to 0.75%, of hydrosulfite stable, but the impatience of the mix of copper, iron, heavy metal ions, with anionic and nonionic surfactants, direct acidic anionic dyes, but not with cationic dyes and active agents , the equivalent of a synthetic resin dissolved use.
Second, the product uses:
Whitening, brightening, mainly used for cotton fabric plant fiber used in papermaking, synthetic detergent, paint and other industries whitening.
Third, the implementation of standard products:
GB GB10661-96
1, Appearance: Light yellow uniform powder:
2, intensity: 100 points
3, the shade near ---- micro:
4, the difference between the values and standards of whiteness whiteness value ≥ -2:
5, water insoluble matter ≤ 0.5%:
6, the moisture content of ≤ 5%:
7, fineness of 100 mesh sieve residue ≤ 10%:
IV Application:
Papermaking furnish whitening process:
Demand in the production process of the fluorescent brightener VBL directly or after its dissolution in water, is continuously fed into the slurry, but should be added before the use of alum or cationic additives, brighteners of the fiber having a moderate to High affinity , the whiteness of the obtained to keep up with the dyeing time and the consistency of the slurry, the consistency of the pulp in the production system, adding brighteners to get the best whitening effect.
Products and the amount of:
The fluorescent brightener VBL generally dry pulp weight ratio: 0.15 to 0.4% of the maximum amount of 0.6%.
Brighteners usage and puree whiteness value increased depending puree whiteness level, the user can be requested ingredients according to the process requirements and the quality of the paper used.
Sixth, packaging and storage:
The product is a drum or metal pail, conventional 25kg / barrel, also can be packed according to user requirements. Storage should be placed in a cool dry place, protect from moisture. Storage period of three years
