Special retention aid filter agent for paper making
Paper special retention aid filter agent is water-soluble organic polymer, soluble in water and form a high viscosity liquid, in low amount can promote the paper fiber retention aid filter and good paper forming effect, improve pulp evenness and paper softness, but also make the strength of the paper performance.
In the use of paper coating, paper special retention aid filter agent with high dispersion efficiency, stable viscosity, less foam, non-toxic, non-corrosive, can improve the solid content of the coating, and good liquidity and scrub resistance, can maintain paper gloss, not easy to become mildew. Paper retention and filter aid can also improve the speed of copy, save beating time, reduce energy consumption, has significant economic benefits.
[Characteristics of papermaking retention aid filter agent] :
1, improve the speed, increase the output, even paper.
2, non-stick cylinder, non-stick cloth, no need to add stripping agent, reduce cost.
3, improve the strength of paper, improve the utilization rate of fine fiber.
4, feel delicate, enhance the status of paper products.
[Paper making retention aid filter use] :
1. Improve production efficiency
In order to improve the speed, accelerate the dehydration of the wet part of the paper machine and the moisture evaporation of the cadres, in order to improve the output, filter aid can be added. In order to be uniform and firm, mordant and diffuser can be added to pulp dyeing. Rosin sizing effect can be increased if synergistic agent is added. If the recycled waste paper contains ink and other substances, you can add waste paper deinking agent, and make pure pulp.
2, improve the quality of paper to give special performance
For example, cement bag paper requires high strength and good air permeability. When beating, the beating degree can not be high. In order to improve the strength of paper, dry strength agent is often added. Napkins and facial tissues require soft, such as cotton, wipe without fuzz, often add softener. Corrosion inhibitor treated rust - proof paper, packaging metal products to prevent corrosion.
3, reduce loss and save the consumption of raw materials
For example, adding retention aid and flocculant in pulp can improve the retention of filler and fine fiber, reduce loss, save raw materials and reduce the pollution of waste water.
4. Improve production operation
Use a blanket cleaner to speed up blanket washing and keep the blanket clean. In the coating often add adhesive, can improve the quality of coated paper. Adding dispersant can reduce the viscosity of the coating for production operation, make the coating uniform, adding crosslinking agent can improve the water resistance of the coating.
