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.
