Product Description


This product is a kind of self-retaining neutral sizing agent which is chelated by a special process. Its outstanding feature is that it greatly simplifies the sizing process and can replace the binary retention aid (cationic starch and polyacrylamide) or unit retention aid system commonly used in the internal and external AKD neutral sizing, and its sizing agent effect, papermaking performance, physical indexes of paper formation and corresponding comprehensive economy The benefit and other aspects have been improved significantly.

It is suitable for all kinds of culture paper, writing paper, board paper, corrugating base paper, fruit bag paper, kraft paper, packaging paper and so on. It can be used in a wide range of pH value (7-9). The most suitable condition for making pulp is pH (7.5-8.5). It can use calcium carbonate filler and can replace the traditional rosin acid sizing and AKD neutral sizing. It is aimed at the current AKD A revolution in sexual sizing.


The dosage of the product is 0.1-0.5% of the absolute dry pulp (the product is converted into a dry meter). When using, it can be diluted 5-10 times and added into the mixing tank and stirred evenly. For large paper machines, the adding point is usually selected at the high position box without dilution, and the dosage can be further reduced after continuous adding by the metering pump. For the paper containing filler, the order of adding is first adding filler and then adding sizing agent. It is unnecessary to add retention aids such as starch and polyacrylamide when using this sizing agent. For example, for the paper with high strength and high filler content, it can be used together with retention and filter aids produced by our factory. The dosage is (0.01-0.05)% and the usage is the same.
五、Product characteristic

1. Good sizing effect and chemical resistance (acid, alkali, lactic acid, ink)

2. It is easy to retain. When the intermediate glue is added into the pulp system, it can be firmly combined with the fiber filler in the pulp through electrostatic attraction and polymer action, which can improve the physical strength of the finished paper (such as breaking length, breaking resistance, folding resistance, tearing resistance, and reduce the amount of reinforcing agent).

3. It has strong retention ability, can retain the fine fibers and fillers in the pulp, save the pulp consumption and reduce the cost.

4. Under the same conditions as acid sizing, some cheap short fiber raw materials can be used to replace the long fiber high-quality raw materials; increase the amount of filler or increase the retention rate of filler, so as to save fiber raw materials, reduce the cost or appropriately reduce the beating degree, reduce the end breakage of paper machine, and reduce the power consumption of beating.

5. Sizing under neutral conditions can increase the strength and whiteness of paper without adding aluminum sulfate. It can also improve the aging resistance of paper, greatly prolong the storage life, and also reduce the corrosion of equipment and prolong the life of paper machine.

6. It can improve the recycling efficiency of white water, reduce the content of BOD and COD in discharged wastewater and reduce environmental pollution.

7. Cheap calcium carbonate can be used as filler to improve paper whiteness and opacity, and improve paper printing performance.

8. The paper is easy to dry under high-speed drying, and the fiber loss is less in the paper making process.

9. Neutral papermaking can enhance the paper strength, reduce the phenomenon of falling powder and hair, and improve printability. Improve the retention rate of fines and additives, reduce pulp consumption and cost. Improve the quality of paper, such as the surface strength, tensile. strength, folding resistance, sizing, opacity, surface smoothness and other indicators are better than those of acid and traditional neutral sizing. Simplify the sizing process, improve the papermaking performance of the paper machine, and there will be no paper making obstacles.
六、Package, storage and matters need attention

1. This product is packed in the 1,000 kg plastic drum

2.Sealed at room temperature, suitable storage temperature is 10-32℃

3. This product is non-toxic, non-combustible, non-corrosive, belongs to non-dangerous good, can be stored and transported according to the general goods, if there is leakage, rinse with water .
