STRUCTURAL STUDY OF THE SURFACE OF WOOD-BASED PANEL MATERIALS (LDSP, LMDF, MDF) USING SEM AND OPTICAL MICROSCOPY METHODS
Abstract
The thesis presents a comparative analysis of the microstructure of widely distributed wood-based panel materials in the market of the Republic of Uzbekistan — particle boards (DSP), laminated particle boards (LDSP), medium-density fiberboards (MDF), and laminated MDF (LMDF) samples using scanning electron microscopy (SEM). Seven types of samples obtained from manufacturers in Russia, Iran, and the European Union were studied at magnifications from ×100 to ×6000, and a total of 95 microphotographs were analyzed. Microstructural parameters were evaluated on a 5-point scale, and an overall quality ranking of the samples was compiled. It was determined that the highest indicators belonged to European LMDF and LDSP samples (30/30 points), while the lowest indicators belonged to the Russian DSP sample (6/30 points).
