Acoustic cellular board with wooden strip core and method for manufacturing acoustic cellular board with wooden strip core

摘要

acoustic cellular core plate listewkowym containing at least three layers designat least one of which is the outer perforated layer (1) and is permanently connected with the at least one inner layer (2) and connected firmly with an inner layer of podporowu0105 (3) in which the outer layer is made of at least trzywarstwowej plywood topolowej thickness of at least 3 mm or with plate thickness of at most 3 mm hdf.and the diameter of holes generated in the outer layer is not greater than 5 mm, the axles are spaced more than 15 mm holes in the corners of the squares.method of manufacturing a listewkowym mobile acoustic records as of listewek wood trees selected from: poplar (populus nigra) and / or spruce (picea abies) and / or pine (pinus sylvestris l.) with a moisture content not exceeding 8% and measuring 4 x 10 mm produces the core and then collate it with posmarowanymi glue, preferably dyspersyjnym based on poly (vinyl acetate),at least one outer layer and a podporowu0105, after which they compiled layers under pressure of not less than 0.8 n / mm2, and the glue layer is applied on the external in quantities not exceeding 150 g / m2.
