Gap Former Paper Machine & Stock Preparation Area

The stock preparation area is where pulp is blended to the appropriate proportion of hardwood, softwood or recycled fiber, refined to impart desired sheet properties and diluted to a specific consistency. Here, various fillers and chemistries are added to improve the strength and printability of the final sheet. Solenis offers one the broadest selection of sizing agents and strength additives in the industry as well as a variety of treatment chemistries to address various process challenges.

  • Biocides
  • Cleaners
  • Defoamers
  • Deposit control agents
  • Dry strength additives

To produce a quality sheet of paper economically, the sheet forming process must be carefully managed and wet end issues, such as deposits, foam and microbial activity, must be proactively addressed. In addition to one of the broadest offerings of retention, drainage and clarification aids in the industry, Solenis offers a variety of proven treatment chemistries to tackle troublesome wet end issues.

  • Acid/alkaline boilouts
  • Deposit control agents
  • Dry strength additives
  • Foam cleaners

With the reduced use of fresh water due to mill closure comes the increased potential for pitch and stickie deposition on press felts and rolls. These deposits not only limit water removal in the press section but also can lead to sheet breaks and defects. Solenis offers an arsenal of products that improve the overall performance of the press section by mitigating these issues and more.

  • Deposit monitoring systems
  • Press felt cleaners
  • Press roll release aids

The pulp slurry used to produce paper enters the paper machine as a blend of 99% water and 1% fiber. While gravity, vacuums and the press section help to remove about 50% of the water from the sheet, the dryer section uses heated cylinders to reduce the water content to approximately 6%. Solenis offers a variety of chemistries that benefit the dryer operation by preventing contaminant adhesion, decreasing doctor blade and cylinder wear, and minimizing the need for cleanings.

  • Deposit control agents
  • Dryer cylinder passivation aids

Sizing agents improve the water resistance and print properties of paper and are applied at either or both the wet end (internal sizing) or the dry end (surface sizing). When applied in the dry end, they are applied at the size press. Solenis offers a complete portfolio of sizing agents to help papermakers meet their grade specifications as well as surface treatments that improve the functional properties of paper and paperboard.
