“…It would not only not need to be placed in a large oven, but would also reduce energy consumption, leading to economic benefits. In the end, a novel composition for a functional powder coating was formulated by blending the base resin with NBN and NHP curing agents, along with additives such as fillers, leveling agents, and defoamers, including 57.1% E12, 1.7% NBN, 15.4% NHP, 20.5% TiO 2 filler, 1.4% SiO 2 adsorbent, 1.1% leveling agent, 0.5% 701B brightening agent, 0.6% 5031 brightening agent, and 0.6% benzoin defoaming agent, following a sequence of processing steps, including grinding, extrusion, cooling, fracturing, and electrostatic spraying [64] (Figures 5a and S4). The curing temperature obtained for the laboratory formulation was 140 • C for 30 min.…”

Thermoset powder coatings exhibit distinctive characteristics such as remarkable hardness and exceptional resistance to corrosion. In contrast to conventional paints, powder coatings are environmentally friendly due to the absence of volatile organic compounds (VOCs). However, their irreversible cross-linking structures limit their chain segment mobility, preventing polymers from autonomously repairing cracks. Dynamic cross-linking networks have garnered attention for their remarkable self-healing capabilities, facilitated by rapid internal bond exchange. Herein, we introduce an innovative method for synthesizing thermoset epoxy containing boronic ester moieties which could prolong the life of the powder coating. The epoxy resin system relies on the incorporation of two curing agents: one featuring small-molecule diamines with boronic bonds and the other a modified polyurethane prepolymer. A state of equilibrium in mechanical properties was achieved via precise manipulation of the proportions of these agents, with the epoxy composite exhibiting a fracture stress of 67.95 MPa while maintaining a stable glass transition temperature (Tg) of 51.39 °C. This imparts remarkable self-healing ability to the coating surface, capable of returning to its original state even after undergoing 1000 cycles of rubbing (using 1200-grit abrasive paper). Furthermore, the introduction of carbon nanotube nanoparticles enabled non-contact sequential self-healing. Subsequently, we introduce this method into powder coatings of different materials. Therefore, this work provides a strategy to develop functional interior decoration and ensure its potential for broad-ranging applications, such as aerospace, transportation, and other fields.

An issue related to using wood and wood products for building structures is to ensure their stability and durability during operation within wide limits. Therefore, the object of this study was a change in the properties of the polymer shell of powder paint on wood during thermal modification. It is proved that in the process of thermal modification of wood, its structure changes, and accordingly, during the polymerization of powder paint, degassing occurs, which affects the polymer shell. Namely, during the thermal polymerization of powder paint at a temperature of 180 °C for untreated wood, shallow bubbles and craters are characteristic of the formed polymer shell. Instead, a smooth surface is marked for a sample of thermally modified wood. Thermogravimetric analysis data show thermogravimetric curves characterized by the loss of mass of the sample of the original wood with increasing temperature due to the processes of dehydration, destruction of hemicellulose and lignin. This is dehydration, accompanied by the destruction of the pyranose cycle, and carbonization to form a carbon residue and a complex mixture of volatile products. Due to this, bubbles and craters are formed in the polymer shell of the coating. Based on the obtained results of adhesion of the polymer shell on wood, which is treated with a mixture of epoxy polyester system with functional additives and a polymerization temperature of 180 °C, the adhesion level is 2.1 MPa. Reducing the polymerization temperature of a mixture of the epoxy polyester system with functional additives to 130 °C increases adhesion by 1.75 times, and the nature of the destruction passes through the polymer shell. For thermally modified wood, the level of adhesion is within 2.1 MPa, and the destruction takes place through the wood. This is due to the increased fragility of the surface after thermal modification of wood

“…The connection methods of panel furniture determine the types of basic panel drilling processes adopted by enterprises oriented towards intelligent manufacturing. These processes mainly include four types: vertical drilling, horizontal drilling, grooving, and milling [10]. By processing the panels according to system-generated drawings using these four methods, and combining eccentric connectors and slotted embedded panel connection techniques during installation, the assembly of the basic panel cabinets can be completed [11,12].…”

The panel furniture industry is experiencing rapid development, with a growing focus on intelligent manufacturing and efficient production. However, in the process of upgrading the drilling process for panel furniture towards intelligentization, still lacks standard optimization methods. To address this issue, we conducted an analysis of the cabinet structure in panel furniture and propose a novel approach that utilizes matrices and sets to represent panel and drilling information, enabling efficient data analysis and subsequent optimization. Moreover, we introduce a comprehensive optimization method comprising the COING (a hierarchical clustering analysis method adapted for panel furniture based on the STING grid method) and AR (Association Rule) techniques, uncovering potential associations and relationships within datasets. To validate the efficacy of the proposed method, we implemented it in the production workshop of Company W. Experimental results demonstrate a 14.01% reduction in drilling frequency and a 3.869% improvement in drilling efficiency compared to traditional design methods. Our findings emphasize the practical significance of the proposed standard drilling optimization method in the panel furniture industry, effectively enhancing drilling efficiency and promoting the transition to intelligent manufacturing.
