Stock Additives
After optimizing mechanical contaminant control methods, including washers, screens & cleaners, the ideal next step is to prevent contaminants from reaching a state where they can become a problem later in pulping or on the paper machine. DuBois provides unique stock additives that prevent contaminant issues throughout the process.
| PRODUCT | PITCH | STICKIES | DESCRIPTION |
|---|---|---|---|
| EXP-P5200 | X | X | A blend of dispersants & polymeric surface-active materials specifically designed to control pitch deposition. It is applied to the pulp mill system to detackify pitch particles before agglomerating. |
| NexShield P103 | X | Controls contaminants & serves as an organic talc substitute. Manages pitch particle size, creating a stable molecular shell that is resistant to melting on heated pulp drying equipment. Facilitates the easy removal of small & stable pitch particles during washing, preventing deposits on process equipment. Acts as an efficient talc replacement. | |
| NexShield X102 | X | X | Stabilizes pitch & stickies particles by modifying their surface charge & encapsulating contaminants in a high glass transition temperature hard shell. Contaminants stay small, dispersed, & non-tacky even at high-temperature contact areas. |
| PS-87 | X | X | A multi-functional pulp mill specialty product. An effective pitch scavenger, preventing pitch & other contaminants deposition on the pulping & drying equipment. Controls anionic trash & contaminants, & also functions as a fluff pulp antistatic agent. |
Fabric Treatment
When preventing deposit issues before the paper machine is not feasible, treatments for fabrics & rolls can be an effective method of contaminant control. Fabric & roll treatments are applied through showering to modify the treated surfaces & make them less attractive to contaminants.
| PRODUCT | FORMING WIRE | PRESS FELT | ROLLS | DRYER FABRIC | DESCRIPTION |
|---|---|---|---|---|---|
| Fabrix Shield B11 | X | X | X | Bonds to the hydrophobic surfaces of paper machine fabrics & rolls, converting them to a hydrophilic state. Mitigates deposit problems on machine fabrics often caused by hydrophobic substances such as stickies from recycled fiber, wood pitch, synthetic sizes & waxes. | |
| Fabrix Shield T10 | X | X | X | Adheres to hydrophobic surfaces, transforming them into a more hydrophilic state, no longer attracting stickies. Enhances the moisture handling of press fabric, reducing new felt break-in time & improving sheet moisture profiles. | |
| Nexus Concentrate 3620 | X | A patented, highly concentrated solution, designed to impart resistance to stickies & pitch deposition on paper machine rolls & surfaces. Maintains cleanliness on roll surfaces, enhances sheet release & minimizes picking & sheet breaks instances. Effective on various roll covers, including ceramic, synthetic rubber, polyurethane & synthetic composite. | |||
| Nexus DC 2440 | X | X | Manages stickies deposition on paper machines with a blend of cationic polymers & other functional agents. Prevents the accumulation of starches, alkaline sizing agents & other materials, effectively maintaining clean roll surfaces & fabrics. | ||
| Nexus DF8 | X | Prevents stickies contamination & dryer fabric filling. Creates a temperature-stable, non-volatile protective layer on dryer fabrics & cans, requiring only a small dosage for effectiveness. Extends intervals between cleaning, improves dryer section efficiency & reduces breaks & defects. |
Cleaners
Cleaning solutions can be valuable additions to stock additives & surface treatments. Fabric cleaning proves effective in eliminating pitch, stickies, & other materials such as strength resins & sizing. Ideally, cleaning should occur during production without adversely affecting machine operation.
| PRODUCT | FORMING WIRE | PRESS FELT | DRYER FABRIC | DESCRIPTION |
|---|---|---|---|---|
| Altrox Accel | X | X | A patented oxidizing cleaner that eliminates recycled fiber contaminants, wet & dry strength resins & Yankee adhesives. Removes gel-like soils that can fill the void volume of a fabric, reduce permeability, increase sheet moisture variability, diminish drying efficiency & shorten fabric lifespan. | |
| Div-O-Kleen Accel | X | X | Formulated to clean fabric on high-speed machines during production. Features a rapid-wetting surfactant package & a distinctive solvent blend. | |
| Felt Scrub Accel | X | X | A patented fabric cleaner that quickly reduces liquid surface tension, allowing it to encapsulate & penetrate soil rapidly. Highly effective at cleaning fabrics during production, even on high-speed machines. Contains a special blend of ingredients that prevent paper fines from swelling in a press fabric, preventing drainage loss & nip sheet crushing during cleaning. | |
| Neutra Solve 504 | X | X | X | A patented cleaner for removing recycled fiber stickies contaminants. Its solvent blend surpasses conventional cleaners like kerosene & mineral spirits in effectiveness, even in smaller doses, with a safer flash point. |
| Sure Safe 460 | X | X | X | A non-corrosive cleaner designed for rapid wetting to optimize cleaning efficiency, even with short dwell time. Serves as an effective alternative to highly alkaline felt cleaners & ensures safety. |
