Determination of Some Technological Properties and Formaldehyde Gas Release in Lignocellulosic Based Interior Design Panels

Aim of study: The aim is to produce lignocellulosic-based interior design panels (LIDP), a type of composite that complies with gas emission standards, from annual facility waste. Material and method: The wood chips of Turkish pine and annual plant wastes cotton stalks, sunflower stalks and wheat stalks were used as test materials. Within the scope of the tests, the water uptake (WU) and thickness increase (TI) values were measured from physical properties and some technological properties (Janka hardness (JH), surface vertical screw holding strength (VSH), nail holding strenght (NHS) and surface soundness strength (SSS)) awere measured. Similarly, the FGR values of the LIDP were determined based on perforator method. Main results: The measurement results of WU and TI in physical properties showed that the test panels did not meet the criteria required in the usage standards. In terms of technological features, as the annual waste plant ratio in the panel matrix increased, the power values also decreased. The best results in formaldehyde gas emissions evaluated according to EN 13986 were obtained in LIDP produced from WCR-SSR mixtures. Research highlights: Investigation of the suitability of annual plant residues for the production of environmentally friendly lignocellulosic-based interior design panels (LIDP) with standard features.
