Smooth processes need the right coating

Nonwoven Materials Industry - Smooth processes need the right coating

Surfaces quickly wear off in many applications

At production speeds of 1000 m/min., even light plastic and nonwoven materials can corrode surfaces. Aluminum surfaces and nonstick coatings quickly wear off in many applications. Wear from SAP powder, hot melt residue and material deposits, guides and angle bars with high friction, glue adhesions on vacuum drums or Lycra fibers that wear out the guides - these are just a few of the factors that require maintenance and lead to downtime.

Unique requirements in each component

Each component has unique requirements in the production process. Aalberts surface treatment has developed coatings to increase your machines' service life, improve your processes and reduce costs. Impreglon offers an array of solutions with exceptional nonstick properties and unrivaled resistance to wear, with its customer-oriented coatings and selection of suitable filler materials - the answer to increasing quality and productivity.

Smooth Processes

need the right coating

At high speeds, the coating must be adapted perfectly to suit the application. We have three examples of how this can be achieved.

Prevention of adhesion to vacuum rolls

In the production of sanitary pads, self-adhesive strips are attached to the bottom of the panty liners to prevent slipping and ensure maximum comfort. Residue sticking to the vacuum rolls is a frequent occurrence when processing the sticky strips.

The favorable nonstick properties of TempCoat®, combined with a smooth surface resistant to wear, ensure uninterrupted production. Downtime is reduced and time spent cleaning is saved.

The TempCoat® coating processes create polymer and fluoropolymer layers with outstanding nonstick properties and very good sliding properties.

Nonwoven materials

Nonstick coating and corrosion protection for surfaces of rolls

In the non-woven materials manufacturing process, cellulose is passed over drying drums, which in turn run over large rolls. The cellulose is dehydrated by the drying drums and converted into a web of fabric step-by-step. The residual moisture causes the material to stick to the rolls. Combined with high production speeds, this means that the surfaces of the rolls are subjected to high levels of wear. The warm, humid environment promotes corrosion.

A special combination of PlasmaCoat® and MagnaCoat® provides the necessary mechanical stability, excellent corrosion protection, outstanding nonstick properties and very good barrier protection in an aggressive hot and humid environment. Machine downtime and expensive damage are prevented. Time-consuming cleaning measures can be eliminated and productivity is increased considerably.

The PlasmaCoat® coating procedure combines the outstanding surface hardness and wear resistance of thermally sprayed metal or ceramic coatings with the nonstick and sliding properties of polymers and fluoropolymers. MagnaCoat® coatings are thick-film polymer and fluoropolymer coatings with a virtually non-porous surface.

Nonwoven-Material

Prevention of blockage in the dryer nozzles

In the production of non-woven materials, wet strips are dried with streams of hot air applying the suspension drying principle. In the process, the strip is transported without contact by a series of air cushions at speeds of approx. 305 m/min. It is imperative for the production environment to be absolutely clean in order to ensure high quality. When the production line is started and stopped, the web tension can vary and material that has not yet dried can stick to the surface of the nozzles.

The PlasmaCoat® coating prevents the strip material from adhering and reduces the accumulation of suspended matter from the environment. It can prevent partial or total blockage of the dryer nozzles.

Advantage for the customer: Prevents machine downtime and time-consuming cleaning and maintenance work. Significantly increases productivity.
