Suitable stickies control chemical suppliers

In the past few years, the recycling rate of paper has continued to rise in the global range. Due to the important complementarity between pure fiber and recycled fiber, paper industry has become one of the most important recycling industries.

The removal of adhesives ("stickies") from pure pulp fibers or recycled paper is accomplished by a combination of enzyme treatment and adsorbents. There are a range of control methods, such as improved pulp end deflection, batch selection, well-designed screening end cleaning system, and more.

The problem of note paper

Recycled paper will bring a lot of pollutants, so it has become the main aspect of the recycling process. In order to solve this problem, a large number of adhesive control chemicals are used in the papermaking process.

Note paper for control

Sticky paper can be controlled in two ways; one is to remove the sticky paper as much as possible. The second method is to prevent residual adhesive from adhering to the sediment. Remember, the mill should always try to remove the sticking first and then do deposit control.

The reason behind this is that sediment inhibition is done to reduce the interference effect of stickiness, which cannot be eliminated. Removal of attachments is a safe method and can be done quickly where there is a drain.

There are various steps to remove stickies, such as pulping, screening, cleaning, flotation and the use of a variety of chemicals.

Type of paste control

There are a variety of binder control chemical suppliers on the market, but you must know them in detail so that you can know which chemical supplier to choose. Here are some of the different chemicals and ways to control adhesives

Use of beta carotene - if used with polyethylene oxide, it is really an effective retention system and can significantly improve the removal of stickies. In this process, the stickies are fixed to the fibers by chemicals and then removed from the process by the paper.

Use diatomite - a mineral that includes skeletal remains of unicellular aquatic plants. It has organic and hydrophilic parts, making it a perfect product for sticky removal.

Cationic polymers - cationic polymers are very common in Deinking and recycling plants. These polymers are commonly used in pulping because they help prevent the formation of secondary stickies. Perhaps the motivation for using cationic polymers is to induce controlled precipitation of colloidal contaminants and immobilization on fibers, which can be easily removed from paper.

Surfactants - the use of surfactants does not completely remove adhesion, but can change surface properties. Surfactants can also be used to treat paper machine clothing, such as wires or felt.

Enzymes - it's a whole new way to break down larger adhesives into smaller ones, which can then be removed from the mil process. The best part of this method is that it reduces the impact on paper quality and brightness.

In this process, esterases are used to break down the adhesive into smaller ones.

Alum separator - alum is used in this process to ensure better retention and standard size. When using alum, you should always be vigilant about the amount of alum, because excessive alum may cause stickies to coagulate in the secondary fiber material.

Solvents and dispersants - there are two types of dispersants, anionic and nonionic polymers. If dispersants and solvents are well mixed, they can resist wet strength. You should choose dispersants based on their compatibility with existing systems.

Conclusion it is not easy to control the adhesive in deinking plant and recycling plant. A variety of methods can be used. However, each factory has a specific situation, so you should choose the best solution after doing proper research.
