OPTIMIZATION OF TECHNOLOGICAL LINES FOR LAMINATION OF FIBER CEMENT PANELS TO IMPROVE PRODUCTIVITY AND PRODUCT QUALITY

This paper examines the operating principles of a fiber cement panel lamination production line, as well as the main technological parameters affecting production efficiency and final product quality, and approaches to their optimization. An industrial PURETE automated lamination line was selected as the research object, and a comprehensive analysis of the technological process was carried out based on actual production conditions. The effects of laminator temperature, pressing pressure, and conveying speed on the adhesion, uniformity, and defect-free quality of the surface layer of fiber cement panels were experimentally evaluated. During the study, a multi factor Taguchi experimental design method was applied to determine the interaction of technological parameters and their influence on product quality. Based on signal-to-noise ratio indicators, an optimal combination of technological parameters aimed at improving product quality was proposed. The results demonstrated the potential to ensure lamination process stability, reduce the proportion of defective products, and achieve savings in energy and material resources. The feasibility of implementing the proposed optimization methods under industrial conditions was substantiated, confirming their practical significance for fiber cement panel production.
