Specification:
Appearance: Light yellow uniform powder
Strength Score 100 (Ratio to Standard)
Moisture, %<5
Water insoluble,%<0.5
Fineness (180um sieve residue)%<10
Performance and characteristics:
1. Good adhesion to fibers
2. It has good alkali resistance, perborate resistance and hydrogen peroxide resistance, and poor acid resistance.
Performance and use: Anionic type, resistant to PH4.5-11. Mainly used in pulp whitening, surface sizing, coating and other processes. It has good acid resistance and whitening effect when PH4.5-7 is better than that of VBL. It can reduce the dosage by 15-25%. Its characteristics are fast dissolving speed, high whiteness and never yellowing. It is the first choice for producing high whiteness paper. It can also be used for whitening cotton, linen, nylon, etc.
Usage method:
1. When the pulp is whitened, BA is added before alum or cationic additives with dosage of 0.05-0.4% (for absolute dry pulp).
2. In surface sizing process, it can be used together with CMC, PVA, starch and synthetic sizing agent of anion or cation.
3. In the coating process, after dissolution, the coating is processed at any stage in the form of aqueous solution.
Packaging: 25kg paper bucket or woven bag lined with plastic bag.
