Introduction of New Pulp Sizing Agents

I. Introduction:

This product is a new type of paste sizing agent, suitable for all saponification of rosin gum papermaking process, compared with saponified rosin, with free rosin content, small particle size, easy to use and so on. It gives the paper a good smoothness, printing suitability and a certain dry and wet strength, good hydrophobic properties and overall waterproof performance is not reached by other rosin gum.

Second, physical and chemical indicators:

Appearance: milky white with blue light, solid content (50 ± 2)%;

Viscosity: (25°C) ≤ 20cp, PH5-7, particle size 0.12μm ≥ 90%, free rosin gum content ≥ 99%, thermal stability 60°C, no condensation in 24 hours, anionic.

Third, characteristics:

1. This product has high sizing, and can be sizing at a higher PH value, reduce costs, save the amount of whitening agent, rosin and aluminum sulfate, reduce equipment corrosion, extend the service life of copper mesh and blankets, overcome summer sizing Obstacles, improve product quality.

2, this product can be used for re-sizing paper or paperboard, in the production of thin paper, can improve the smoothness of the paper.

3, this product can be used with anionic wax emulsion, can be internal sizing, surface sizing can also be given to give the paper a higher sputum (including water, anti-blood, anti-emulsion) elasticity and gloss, can be produced Asbestos paper, meat packaging paper, paper cup paper and fruit paper and other special paper.

4, the use of this product can save 50% of aluminum sulfate than ordinary rosin, when used without changing the process equipment, direct cold glue to adjust the use of more convenient and simple.

Fourth, the use of methods and dosage:

1. Dosage: 0.2%--0.5% of absolute dry pulp, ie, 2-5 kg ​​per ton.

2. How to use: The product is diluted with cold water to a concentration of 2% and gradually added to the pulp. The mixture can be evenly mixed, and the aluminum sulfate used can be appropriately reduced.

V. Precautions:

1, can not be diluted with hot water, should not be mixed with saponification rosin gum, so as not to affect the sizing effect.

2. When reducing the amount of aluminum sulfate, it is not possible to make the pH of the Internet greater than 7. If a suitable amount of retention agent is added, the sizing effect will be better.

3, the product is basically non-toxic, but not edible.

Six, packaging, transportation and storage:

200 kg and 50 kg plastic barrels, this product should be stored in a cool, ventilated place, avoid sunlight, storage environment temperature must not exceed 40 °C, this product is non-flammable, can be transported by highway railway.
