PAPERMAKING CHEMICALS
Retention Aids / Coagulants / Fixing Agents
Retention Aids
Retention aids improve drainage and increase retention of fine particles.
They function as both productivity aids and product improvement since they increase speed and increase fines retention.
They improve the clarity of the waste water and greatly reduce the negative environmental impact of water reuse.
RETENTION AID RD Series
- Improve retention of the fiber, fine, and filler in wide pH range(from acidic paper to alkaline paper).
- Improve runnability and productivity by enhancing drainage in the forming section.
Product name | Main components | Ionic | Non-volatile(%) | Viscosity (mPa・s) | pH | Characteristics |
---|---|---|---|---|---|---|
RD7144 | Cationic Polyacrylamide Resin | Cation | 8 | 50~250 | 4.5~5.5 | High cation drainage retention agent. Lower viscosity than general drainage retention agents. |
Coagulants
Coagulants are used to control anionic trash in the paper mill, to reduce and control deposits derived from adhesives and other contaminants contained in recycled pulp.
This increases the productivity of the paper machine.
COAGULANT AC Series
- It blocks anionic impurities contained in the papermaking system and suppresses pitch troubles.
- They coagulate the anionic materials found in recycled papers and help retain them without flocculation of themselves in the paper.
Product name | Main components | Ionic | Non-volatile(%) | Viscosity (mPa・s) | pH | Characteristics |
---|---|---|---|---|---|---|
AC7314 | Modified Polyacrylamide | Cation | – | 1000~6000 | 2.5~4.5 | Prevents agglomeration of anionic contamination and adhesive substances, and reduces pitch troubles. |
Fixing Agents
Fixing agents are used to improve retention of internal sizing agents and to enhance sizing degree.
They also reduce machine deposits caused by internal sizing agent.
FIXING AGENT FX Series
- Improve the retention of AKD / ASA / Rosin sizing agents that allow the lower dosage of using sizing agents.
- Increase the rate and the degree of AKD sizing in shorter time.
Product name | Main components | Ionic | Non-volatile(%) | Viscosity (mPa・s) | pH | Characteristics |
---|---|---|---|---|---|---|
FX7200 | Modified Polyacrylamide Resin | Cation | 15 | 1000~7000 | 3.0~5.0 | Improve the fixation of sizing agents and promote sizing effect. Contribute to coagulating effects and improve paper strength. |
Papermaking Process Improver
Papermaking Process Improver PM Series
- Improve drainage, freeness, and retention, thereby improving operability and productivity.
- Reduce chemical usage via synergistic effect with dry strength agents and sizing agents
Product name | Main components | Ionic | Non-volatile(%) | Viscosity (mPa・s) | pH | Characteristics |
---|---|---|---|---|---|---|
PM7380 | Modified Polyacrylamide Resin | Amphoteric | 20 | 4000~10000 | 2.5~4.5 | A general-purpose product that can be used in a wide range of papermaking conditions. |
PM7450 | Modified Polyacrylamide Resin | Amphoteric | 20 | 4000~10000 | 2.5~4.5 | Demonstrates excellent drainage and retention in conditions of high electrical conductivity in the papermaking system. |
PM7460 | Modified Polyacrylamide Resin | Amphoteric | 20 | 4000~10000 | 2.5~4.5 | Highly effective even with a small amount of aluminum sulfate. |
