Mechanical properties of structural particleboard and termite and decay resistance
نویسندگان
چکیده
The mechanical properties and termite decay resistance performance of wood-based panel used in wooden houses were evaluated. physical properties, along with the levels, commonly panels, including oriented strand board, structural particleboard, particleboard for use interior, compared. complied physical, mechanical, formaldehyde emission standards International Organization Standardization Japanese Industrial Standard, surpassing requirements board. exhibited excellent water a consistent performance. Decay tests classified as “Resistant,” mass losses 7.82 to 12.72% (white rot) 14.69 16.55% (brown rot). Pine (Pinus densiflora) board no resistance, exceeding 45%. demonstrated superior resulting 100% mortality three days without chemical treatment. water, decay, which can be an advantage wooden-house construction terms maintenance.

This study evaluated the effects of a number of chemicals on the physical and mechanical properties and fire, decay, andtermite resistance of oriented strandboard (OSB) panels. Disodium octaborate tetrahydrate (DOT), boric acid (BA), melamine phosphate (MP), and a BA/DOT mixture were sprayed onto the furnish at varying concentrations. Thepanels were tested for thickness swell, water absorption,...

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
