Lumpy flat half-finished product of composite multilayer material and process and apparatus for producing such lumpy flat half-finished product

摘要

a semi-finished product is tvoren circuit substrate pieces stitched together with the length of the nepresahuju00edcu00ed 5 m u0161u00edrkou nepresahuju00edcu00ed 2.5 m and the heftiness 0.3 to 2.0 mm.which is on one or both of its sides opatren one - or vu00edcevrstvu00fdm silt and plastic on the fat 0.2 to 5 mm.while the latter is the plastic deposition and / or reakcnu00edm product layer of liquid polymeric smesi.areal substrate is with the advantage of material selected from the group consisting of raw steel sheet, galvanized steel sheet, a galvanized steel sheet or be to our mutual varnished.an aluminum sheet or plate based on another metal.plastic liquid polymeric smesi is at least one polymer of the group with the advantage of including vinylidene chloride polymers and / or copolymers, especially polyvinyl chloridepolymers and / or copolymers of acrylic acid or metakrylovu00e9 and their derivative. liquid polymeric dispersion or solution smesu00ed can be plastic and additives.the solution concerns the way production of this piece of product, and device for implementation of this way.
