Influence of anionic trash catcher pretreatment on the

Examples demonstrated previously include the following: When a bleached chemithermomechanical pulp was pretreated with a starch-based fixing agent (SBF), the adsorptions of fluorescent whitening agent, tinting dye, wet strengthening agent, dry strengthening agent, neutral sizing agent, and retention agent onto fibers were all improved, and the i...

Influence of Anionic Trash Catcher Pretreatment on the

Cationic dry strength agents (DSAs) are commonly used for paper strengthening. However, before they are applied, another chemical called an anionic trash catcher (ATC) is often used to pretreat pulp to neutralize the negative dissolved and colloidal substances (DCS), increasing the effectiveness of the subsequently added cationic DSA. However, in many cases, the negativity of the fibers is

Anionic trash control in high-yield pulp (HYP) containing

ABSTRACT: High-yield pulp (HYP) and recycled fibers containing anionic trash are being used increasingly in the manufacture of various paper grades. Traditionally, anionic trash catchers (aTCs), such as Pei, CPaM, and poly-DaDMaC, are used to minimize the anionic trash problem. in this work, we studied an alternative aTC, highly substi-

Improving sizing performance of middle layer of liquid

Among them, the concentration of anionic trash and lipophilic extract have increased, which makes various cationic additives to the papermaking process lose their effectiveness. So the retention of cellulosic fines and fillers in paper becomes inefficient, and paper properties can be negatively affected (Wang and Zhang 2013).
