Deinking Agent for Waste Paper SF-2

1. Brief Product Introduction: 
The product is composed of surfactants, inorganic salts and special additives. It has the advantages of small dosage, low cost, quick penetration, moderate foaming, high deinking rate, high dispersion and emulsification, high whiteness and fiber loss Etc. It is suitable for deinking of waste paper, such as newsprint paper, lace paper, book paper, periodical magazine and so on, which is suitable for flotation and washing.

2. Performance Index: 
Appearance : White powdery solid 
Content (%): ≥90
PH: 10-13

3. Characteristics: 
1. The product can effectively disperse and refine the black, color ink of the pulp, which can remove them from the surface of paper fibers. And it makes the black, color ink to disperse in water as emulsion shape. It can dissolve the oil substance of inks (such as mineral oil, vegetable oil, solvent oil, and unsaturated fatty acids, etc). The product can achieve the purpose of removing ink by making the carbon black, pigments and other small particles losing the adhesive property so as to disperse in the aqueous solution. 
2. The product is with excellent thermal stability, and will not decompose at high temperature. It is applicable to high temperature deinking(70℃). 
3. The product is with less damage to pulp fiber, which will improve the quality of recycled pulp and increase the amount of papermaking. 
4. The product is with high performance of biodegradable and non-polluting, which is good for environmentally friendly and sewage treatment. 
5. The product can work with oxidant and reducing agent for achieving better performance, which will improve the brightness of pulp. 
6. The product can get better effect when using under condition of alkaline (it is not applicable in acid conditions). 
7. After adding into the waste paper pulp, the product should be mixed with the pulp at a certain temperature for some time and then get into the next process, which will get better performance of deinking. 

4. Using method recommended: 
Deinking agent: 0.3-0.5 % (increase or decrease depending on the pollution of pulp). 
Caustic soda: 2%. 
Sodium silicate: 5% 
Temperature: (70-90) ℃ 
5. Packing and storage: 
1. Packing in 200kg/bag. 
2. Storage temperature: ≥5℃. Stored in a dry place away from light
