Process for producing construction panels

摘要

The invention relates to a process for producing construction panels which comprise organic and/or inorganic fibres as reinforcement, with the use of cellulose fibres, and at least one inorganic binder, such as cement, and additional fillers if appropriate, the unfinished panels being subjected to treatment at elevated pressure and elevated temperatures produced by steam. The process is to be constituted such that damage to the cellulose fibres is avoided, both during production and during use of the construction panels. For this purpose, it is provided according to the invention for the cement to have a low sulphate proportion of less than 2% and for the unfinished panels to be treated at pressures of 8 bar at most over a time of up to 8 hours.
