Types, properties and applications of surface sizing agents commonly used in papermaking

Our company's newly developed water-soluble chitosan solid surface size agent, originated from Japan's deep-sea rich Marine natural organic raw materials, with the help of modern Marine bioengineering technology of new biological agents. It uses starch as the carrier, combines various substances in starch with its unique physical properties, completes the reaction in the paper page gluing drying instantaneously, forms a strong and ductile network structure layer, thus giving the paper excellent surface strength, and has the noble reputation of surface sizing agent.

First, product characteristics

1, the product is solid, to solve the transportation distance, packaging and inventory;

2, the product is weak anionic, with whitening agent, AKD surface sizing compatibility;

3, the product is water-soluble chitosan sizing agent, can be miscible with water at any rate, the product fills the domestic gap;

4, the product is molecular level, ultra-low dosage, the maximum dosage of 200g/ ton paper, is the traditional surface sizing agent dosage 1/20;

5, the product is environmentally friendly, food grade, non-toxic, tasteless, no VOC;

6, the product is reactive, and starch groups in the drying part to complete the reaction, the internal bond strength and interlayer bond strength is better than polyvinyl alcohol, styrene and C film sizing agent, with excellent surface strength;

7, the product and starch to form a chemical film, reduce paper permeability, excellent moisture resistance;

8, the PH value of the solution is weak alkaline, and the mixture of starch (acidity) is neutral, preventing equipment corrosion.
