Product Description

Cationic starch
Cationic starch is made by reacting corn starch with a quaternary amine to make the starch carry cations. Later, it goes through a series of washing, pressing, drying, refining and packaging. Mainly used for adding in pulp in papermaking process.

Features
1. The gelatinization temperature is low, the paste liquid is clear and transparent, and it will not separate after being placed for a long time.
2. It can absorb negatively charged fibers and fillers, improve the retention rate of fine fibers, and reduce the concentration of white water.
3. Improve the ash content, folding endurance and surface strength of the finished paper.
4. The degree of substitution can be adjusted according to the actual production situation.




Instructions
1. Completely dissolve the dried starch with clean water at room temperature in a steaming container equipped with a heater and a mixer to make a concentration of about 4%~6% 
2. Heat the prepared starch milk to 90~95ºC, and continuously stir and mix for 20~30 minutes at this temperature until the starch paste is completely gelatinized (transparent and uniform).
3. Put this gelatinized starch paste in a storage container, dilute it to 0.51% concentration here, and cool to 50-60°C before adding it to the sizing point.
