Herein, a beech wood dowel reinforced with a self-tapping screw (composite dowel in brief) is proposed. Composite dowels were welded into the predrilled holes by high speed rotation. Force-displacement curves were obtained using a single-shear and dual connection. A double-peaked pattern was found in the bearing process, indicating that the wooden dowel and the self-tapping screw had a synergistic bearing effect in the bearing process. Regarding the failure mode, the self-tapping screw and the wooden dowel were bent, whilst the default wooden dowel fractured. Further, the numerical simulation was carried out using the finite element analysis software ABAQUS, and the result differed from the test value by only 4.30%, showing a high prediction accuracy. The study of the bearing capacity of the composite dowels provides a theoretical basis for the practical application of wooden dowels reinforced by self-tapping screws.

“…A coating process is widely applied on wood surfaces. The adhesives used in the most coating processes, like the adhesives used in the furniture assembly process mentioned above, can produce harmful substances [6], causing a lot of pollution. Environmentally friendly materials should be protected and reasonably utilized.…”

A nano-silver solution, urea-formaldehyde resin-coated nano-silver solution microcapsules (AgNPS@UF), and melamine-formaldehyde resin-coated chitosan-modified nano-silver solution microcapsules (CS-AgNPS@MF) were added into the coatings at different contents for comparative tests to explore an anti-bacterial agent with the best anti-bacterial properties in the water-based coatings on Andoung wood (Monopetalanthus spp.). As the content of anti-bacterial agents increased, AgNPS@UF had the best anti-bacterial property towards Staphylococcus aureus and Escherichia coli, with anti-bacterial rates of 79.0% and 82.1%, respectively. The optical and mechanical properties of the coating quickly worsened as the content of anti-bacterial agents increased. The anti-bacterial coatings with AgNPS@UF have the minimum chromatic aberration change of 6.5. The anti-bacterial coating with 5% content of AgNPS@UF decreased the aging rate. This coating had good optical properties, and its liquid-resistant level is 2. When the 5% content of AgNPS@UF was added, after high-temperature accelerated aging and ultraviolet (UV) aging, the anti-bacterial rates of the coating with AgNPS@UF decreased toward Escherichia coli from 82.1% to 62.2% and decreased toward Staphylococcus aureus from 79.3% to 61.1%, respectively. This shows that the coating had a long-lasting anti-bacterial property. The anti-bacterial property of the coating after high-temperature accelerated aging was superior to that after the UV aging. The incorporation of AgNPS@UF in water-based coatings protects people from the risks of Escherichia coli and Staphylococcus aureus more effectively with long-lasting property. The research results provide a reference for the preparation of anti-bacterial water-based coatings on the surface of the Andoung wood.

“…In the research findings of enhancing the antibacterial properties of water-based coatings, metal antibacterial agents or metal and natural composites of antibacterial agents are widely used [16], but little is reported about the natural antibacterial agents. Some natural antibacterial agents suffer from poor processing properties [17,18], unstable chemical properties, and other problems [19]. Therefore, the development of natural antibacterial agents in water-based coatings is limited, making it difficult to produce on a large scale.…”

To investigate an impact of microcapsules on water-based coatings for a medium density fiberboard (MDF), three types of aloe emodin microcapsules prepared at a 3.0% concentration of SDBS, OP-10 and TWEEN-80 emulsifiers were added to the water-based coatings and applied on a MDF surface. Then, three sets of coatings were tested. Antibacterial properties of three groups of coatings on MDF surface increased with the addition of aloe emodin microcapsule content, and antibacterial properties of the water-based coating against Escherichia coli in the three groups were slightly superior to that of Staphylococcus aureus. The water-based coatings on the MDF surface with SDBS as the emulsifier showed the highest antibacterial rates of 74.1% and 66.0% against Escherichia coli and Staphylococcus aureus, respectively. The antibacterial rates of 70.0% and 62.8% were achieved for the OP-10 emulsifier group, and 67.0% and 61.9% for the TWEEN-80 emulsifier group, respectively. The aloe emodin microcapsules prepared at a 3.0% concentration of SDBS, OP-10 and TWEEN-80 emulsifiers inhibit bacterial growth and improve the mechanical and optical properties of coatings. It supplies technical references for the utilization of aloe emodin microcapsules to the antibacterial coating on the surface of wooden furniture.
