The analysis of microplastics is mainly performed using Fourier transformation infrared spectroscopy/microscopy (FTIR/ μFTIR). However, in contrast to most aspects the process, for example, sampling, sample preparation, and measurement, there less known about data evaluation. This particularly critical step becomes more important if a large number samples has be handled. In this context, it concerning that commonly used library searching not suitable identify from real environmental...
Adding reticulated basalt fibres to wood-based panels as reinforcing materials can improve their strength-to-weight ratio and thus increase material efficiency. This study investigates the effect of different surface modifications on adhesion with binders commonly used in panel industry. The coatings were an acrylate polymer, ureido-silane a combination both conjunction urea-formaldehyde (UF), melamine-urea-formaldehyde (MUF), phenol-formaldehyde (PF), phenol-melamine-formaldehyde (PMF)...
In this study, polyester powder based on iso- and teraphthalic acid was deposited with an atmospheric plasma jet. The fed into the effluent zone European beech wood (Fagus sylvatica L.), Grand fir (Abies grandis Lindl.) medium density fiberboard (MDF). substrates were annealed subsequent to coating process. To exclude decomposition of layers by treatment, surface chemistry has been examined X-ray photoelectron spectroscopy (XPS) Fourier-transform infrared (FTIR) compared reference....
In this study, various wood material sources were used for the manufacture of wood-polymer composites (WPC). The materials categorised as virgin particles (VWP), reprocessed WPC (RWP) and recycled thermoset composite (RCP) derived from two sources, three-layer particleboards, medium-density fibreboards (MDF) boards, or different wood/polypropylene composites. All produced wood-polypropylene compounds contained 60% manufactured using a co-rotating extruder. Malleated polypropylene was...
Wood-plastic composite (WPC) based on a polylactic acid (PLA) matrix is promising material since it biobased, degradable, sustainable, and 3D printable. However, due to its coloring, visible layers after 3D-printing, small build volumes of these printers, coating or gluing parts might be required. This study investigates the influence dielectric barrier discharge (DBD) plasma treatment PLA-based WPC activate surface improve, e.g., capabilities. X-ray photoelectron spectroscopy (XPS)...
In this study, a polypropylene (PP)-based wood–plastic composite with maleic anhydride-grafted (MAPP) as coupling agent and wood content of 60% was extruded specimens were injection molded. The samples plasma treated utilizing dielectric barrier discharge (DBD) setup three different working gases: Ar/O2 (90%/10%), Ar/N2 synthetic air. This process aims to improve the coating gluing properties otherwise challenging apolar surface PP based composites (WPC). Chemical analysis X-ray...
Recent advances in large-scale thermoplastic additive manufacturing (AM), using fused deposition modelling (FDM), have shown that the technology can effectively produce large aerospace tools with common feed stocks, costing 2.3 $/kg, such as a 20% carbon-filled acrylonitrile butadiene styrene (ABS). Large-scale machines build-volumes range of cubic meters and use commercially available pellet feedstock thermoplastics, which are significantly cheaper (5–10 $/kg) than filament feedstocks for...
In contrast to conventional coating processes such as varnishing, plasma powder deposition by means of an atmospheric pressure jet on wood is not yet widely used. A key advantage this process that volatile organic compounds and solvents are avoided. the present work, European beech (Fagus sylvatica L.) pine sapwood (Pinus sylvestris were coated with polymer (polyester), metal (aluminum silver) or oxide (bismuth oxide) particles. Furthermore, a layer system consisting polyester was...
In recent years, awareness regarding sustainability and the responsible usage of natural resources has become more important in our modern society. As a result, wood as building material experiences renaissance. However, depending on use case, protective measures may be necessary to increase wood’s durability prolong its service life. The chemical vapor deposition (CVD) parylene-N layers offers an interesting alternative solvent-based potentially environmentally harmful coating processes....
