Abstract
This article is focused on detection microorganisms appearing during production of gypsum plasterboards. The research is carried out within the project TAČR ZÉTA TJ02000235 Sádrokarton se zvýšenou odolností proti bilogické degradaci (Gypsum plasterboard with increased biodegradation resistance). This article shows first part of this issue what was detection of the most critical place of production, where is the highest risk of bacterial contamination and it open the area to find suitable modification of production process or recipes of gypsum plasterboards.
Highlights
Gypsum plasterboard is basically a composite material that consists primarily of a gypsum core and paper
There was a massive expansion of this type of construction in the early 1990s in the Czech Republic, when imported gypsum boards from neighboring countries first began to appear on the market, and in the mid-1990s, gypsum boards produced domestically [1]
All components are mixed in main mixer and gypsum slurry is put between bottom and upper paper and this slurry together with paper continues through forming table to the setting (No.4)
Summary
Gypsum plasterboard is basically a composite material that consists primarily of a gypsum core and paper. It is the most widely used element of dry construction, which spread in Europe in the 1970s. The information about the effect of the use of recycled material based on gypsum on the properties are mentioned in tasks from years 2018 and 2019 [2, 3]. From many of them is popular detection and solution for ETICS [5, 6] and last but not least problematic with organism in wood construction [7] With plasterboards have these topics similar base – stucco and gypsum like binder and paper like a product of wood. The target of this research is find the most critical place of production, where is the highest risk of bacterial contamination
