2021-06-19   Pageview:524

Waterproof wax emulsions are used for textiles, non-woven fabrics, and paper fibers, which can improve the water repellency and effectively improve the color strength without affecting the reprintability.

1, Textiles, non-woven fabrics, and paper are waterproof with fibers.

2, Thermal paper coating application. Paper waterproof wax emulsion is used for thermal paper coating, mainly used for printing paper and labels in supermarkets. Effectively combine with the thermal layer to prevent excessive abrasion of the thermal print head.

3, Food packaging paper/box coating. It has the functions of preventing moisture (water vapor) and oil/grease. Recommended reading: Uses of liquid wax

Tianshi new model waterproof wax emulsion has excellent waterproof function and environmentally friendly. Same index with repsol wax emulsion.

In the process of papermaking, most of the paper has inner sizing material, which can make the inherent absorbent web of the paper fiber have ideal water resistance strength. Traditional fillers generally use resins, such as wax emulsions, which can replace 20%-40% of traditional resins. Adding wax emulsion can reduce the moisture absorption of paper and promote the uniform distribution of colloid in the paper fiber structure.

Another advantage of adding wax emulsion is that it can offset the influence of the resin binder when mixed with various pigments, so the printability can be improved and the printing efficiency can be improved. The sized paper in the beating machine can usually be further processed and refined through its surface sizing material or coating.
