What is a Starch Filter Screen Basket? And What are its Main Applications?
The starch filter screen basket used in paper making is a specialized equipment for uniformly sizing starch adhesive on the surface of paper. Its main function is to improve the water resistance, ring pressure strength, and printing suitability of paper. Its core function is to combine starch glue with surface sizing agents through screening or coating processes to form a uniform coating.

The Function of Starch on The Paper Machine
Starch is an important additive in the papermaking process, and its role in papermaking mainly includes the following aspects:
1. Increase the strength and smoothness of paper: The addition of starch can make the surface of the paper smooth and flat, while also enhancing the strength of the paper and preventing tearing.
2. Improve printing quality: Appropriate starch dosage can improve the printing quality of paper, making it more glossy and resilient, and the printing quality clearer.
3. Increase production efficiency: Using the appropriate amount of starch can be used for paper processing and starch recycling, effectively saving production costs.
Starch Spray on The Foudrinier Paper Machine Forming Section
The process of applying starch granule suspension to wet end formed paper web by spraying. This technology is a method to improve the bonding strength of paper and has always been of concern to paper manufacturers. Compared with the addition of starch pulp, the retention rate of starch particles sprayed on the web is higher on the surface of the wet paper web. The starch particles and the fibers on the surface of the wet paper web are evenly mixed together and heated in the dryer cylinder to gel, so as to improve the adhesive strength of the paper Compared to starch surface coating, starch mesh spraying has little effect on the dryer load of the dryer cylinder at the back of the paper machine, making it more suitable for cardboard production using waste corrugated paper as raw material.
