Manufacture parameters of thermal insulation slabs from secondary raw materials

Abstract

Formation peculiarities of ecological thermal in-sulation slabs, which have been not produced in Lithuania yet, are presented in this article. The chosen raw materials are available in our country. Two sorts of organic fibre, waste paper fibre and secondary assortment waste fibre, were analysed. It is determined by analysis, that the re-quired structure of homogeneity has the fibre from secon-dary assortment waste. Macrostructural levels of organic thermal insulation, fibrous carcass structures of organic fibre formation located in thermal insulation material and inter-insulating binding material melted fibres bond struc-ture were analysed. To determine forces of thermal insula-tion slab and binding material bond structure, the ellipsoid algorythm of contacting irregular particles was applied.
