Extrusion moulded formed panels

摘要

The panel is formed from shredded paper, esp. recycled paper, vegetable material, or the paper contents of compound materials, or a mixt of all these, and a binding and/or waterproofing material. This consists of sodium water glass, with hardener or neutralizer and/or starch with additives, and/or adhesion aids, and/or plastics from compound materials. The formed panels are waterproof or water-resistant. The portion of binding and/or waterproofing material, and/or adhesion aids, is higher in the edge areas. The hardener or neutralizer consists of e.g. silicic acid, to neutralize the alkaloid.
