Ruigang Yuan DOI:10.26789/jnhb.v9i1.2051 AbstractWith the intensification of the global energy crisis and the increasing awareness of environmental protection, the research on energy-saving construction technology for civil buildings has become particularly important. This article takes a newly built residential community project in a certain city as an example to explore in detail the energy-saving construction technology of civil building envelope structures. The article introduces the project overview, including project positioning, target customer groups, and energy-saving design concepts. Next, the energy-saving construction techniques for exterior walls, exterior doors and windows, and roofs were analyzed in detail, including material selection, construction methods, and quality control measures. In addition, the article also discusses specific measures for quality control, cost protection, and quality management of construction materials. Through these detailed technical analyses and quality control measures, this article aims to provide reference and inspiration for energy-saving construction of similar projects, in order to maximize the economic and social benefits of building energy conservation.

Xiaotong Xia, Xin Wang, Jing Jiang, Yurong Yao, Shuchuan Peng DOI:10.26789/jnhb.v9i1.2054 AbstractIn this study, raw biochar (BC600) was prepared via KOH-activated pyrolysis of chestnut shell powder, followed by Zn/Mn co-modification to synthesize modified biochar (MBC600). The variations in surface microstructure and chemical composition of the biochar were investigated through characterization techniques. Adsorption experiments were conducted to evaluate the Cr(VI) removal performance of MBC600 in aqueous solutions, with adsorption kinetic and thermodynamic models fitted to elucidate the underlying mechanisms. Cycling experiments were performed to assess its stability and regenerability.The results demonstrated that MBC600 exhibited abundant functional groups dispersed on its surface and within pores, with its specific surface area and pore volume increased by approximately 4.5-fold, significantly enhancing adsorption capacity. At a dosage exceeding 1.5 g/L and an initial solution pH of 3, over 95% Cr(VI) removal efficiency was achieved within 2 h, with a maximum adsorption capacity of 44.6 mg/g. The adsorption process was spontaneous and dominated by chemisorption, following a multilayer heterogeneous diffusion mechanism, and characterized as exothermic with increased entropy. After five cycles, the removal efficiency remained at 74.4%. The primary removal mechanisms included electrostatic attraction, redox reactions, and complexation.

Linpeng Wang, Guoliang Li, Yun-kai Yang, Jing Yang, Dalin Gao DOI:10.26789/jnhb.v9i1.2055 AbstractThis paper conducts an in-depth analysis of the issue of cigarette pack overflow glue issues during the production process of the YB45 Hard Packet Packer. The analysis concludes that the main causes of glue overflow are the misalignment of glue dot positions and excessive glue application. Among these, the misalignment of glue dots may be caused by factors such as wear of the conveying rollers, accumulation of dirt on the fan-shaped conveying rollers or wear of the counter-support rollers, uneven pressure from the conveying channel cover plates, improper installation of the second glue cylinder, and loosening of the glue application counter-support rollers. Excessive glue application, on the other hand, is often due to wear of the glue scraper plate, malfunction of the glue level detector, or damage to the surface of the glue application roller. Based on the above analysis of causes, this paper proposes a series of specific and feasible solutions and introduces an improvement measure of replacing fixed acrylic sheet with movable one to enhance maintenance efficiency. The research shows that optimizing equipment maintenance and operational processes can effectively reduce the occurrence of glue overflow in cigarette pack, thereby improving product quality and production efficiency.
