| Popis | Laminated glasses used in civil engineering are produced by layering two and often more glass plates, between which a safety foil (interlayer) is placed. The layering and lamination of plates allow not only to increase the standard load-bearing capacity and improve the acoustic insulation properties of the glass, but above all, it enables its residual load-bearing capacity after breakage and prevents the release of glass shards due to their high adhesion to the safety film. For several decades, PVB (Polyvinyl butyral) foils have been the most commonly used interlayer in the laminated safety glasses (LSGs) for building glazing of the standard design to the simplicity of lamination, good safety after breakage and low cost. However, LSGs are increasingly used as a load-bearing and structural support element in modern functional buildings. For these applications, an ionoplast (ionomer-based) interlayer is more suitable, due to its several times higher strength, up to 100 times greater toughness, and considerably higher stability under prolonged load and at higher temperatures. The ionoplast interlayer in LSGs does not depend on the type of glass support and has greater resistance to ageing and clarity. The listed properties of ionoplast interlayer enable to production of thinner and lighter, more safety and high-quality LSGs with the larger dimensions of the minimal framing and point supporting as well as load-bearing glass elements (beams, stairs, floors, railings, etc.). |
