CATIONIC STARCH

The starch with cationic feature which is made of natural corn starch reacted with cationic by etherification.

Ⅰ CHARACTERISTICS

Low gelatinization temperature, clear solution, better fluidity, stability viscosity, decreased retrogration,

with higher dispersion and solubility.

Ⅱ CATIONIC USAGE IN PAPER MAKING

1. the cationic starch is With positive electrical charge, the fiber and filling in paper pulp are with negative electric charge,

most of chargers can be absorbed by cationic starch. Then improve the attachment rate of tiny fiber

 partials, reduce energy consumption.

2. the cationica starch Mainly used as wet end additive, combine with fillings and fibers, Accelerate water filter, improve

 paper machine speed, and reduce pollution and energy consumption.

3. The cationic starch Also used as surface adhesive agent in high grade paper making, improve paper

surface strength and drying rate, prevent powder off and fiber granular off. Also used as coating sizing agent.
