SPECIFICATIONS
PROPERTY 1.Easily used and can be mixed with water at any ratio. Suitable for automatic continuous addions&gauge. 2.Excellet acid resistance and excellet whitening effect even in low PH value solution. 3.Advanced nanofiltration membrance technology is applied for this material and has low salinity and better store stability under normal temperature. 4. Compared with other products, FBW-APC has better sunlight fastness and alkaline resistance. 5. Kept stable above 0℃ and freeze under -3℃, but have no influence on its usage when heated and dissolved again.
APPLICATION 1.Fluorescent whitening agent for paper pulp bleaching 2.Fluorescent whitening agent in the process of surface gluing 3.Fluorescent whiteing agent in the process of coating
PROCEDUR 1.Addition to the stock: adding without dilution. Usual dosage: 0.05-1.2% on dry pulp. 2.Addtion via size press: combined with starch,CMC,PVA and other products designed for surface sizing. Usual dosage:0.5-10 g/l 3.Addtion to the pigment coating mixtures: adding in any stage of building coating material.Good performance with the carrier of CMC,PVA and starch.Usual dosage:0.1-1.4% on dry pigment.
