Solving Glue Transfer Challenges with Peristaltic Pumps
A world-renowned paper tissue manufacturer is enjoying multiple benefits following the selection of peristaltic pumps for the transfer of a glue/ink mixture used in its manufacturing process.
Careful consideration must be taken with pump selection when handling the transfer of glues. Depending on the type, these adhesives can be highly viscous and often harden and solidify when exposed to air. Glues are typically either water or solvent based; in this instance, the former is relevant.
Polyvinyl acetate (PVA) is a common example of water-based glue, comprising natural or synthetic soluble polymers that are added to water to form the liquid. This type of product only works if the applied surface is permeable (e.g., wood and paper). The glue sets once the water has evaporated from the surface; the bond can then be broken easily with the reapplication of water. These glues are popular as they are low in cost and environmentally friendly.
