Characteristics of Particleboard Made from Sedar Chips and Wood Slabs (TECHNICAL NOTE)
This study was Characteristics of manufacture particleboard (PB) from sedar and wood slab of impregnated with UF. The chips were divided into coarse chips with dimensions of 2-4 mesh and fine chips of 30–60 mesh, urea formaldehyde (UF) resin solution at concentrations of 45 %, and 55% sprayed on these chips about 1 min until 10% to dry weight chips, they were dried under 5% moisture in a dram d...
متن کاملBiological degradation of resin acids in wood chips by wood-inhabiting fungi.
Resin acids in many pulp mill effluents are primary sources of toxicity to fish. Inconsistent biological detoxification of chlorinated and nonchlorinated resin acids in secondary treatment of pulp mill effluents is a continuing source of concern. An alternative approach to effluent detoxification is to remove or modify the toxic compounds present in wood chips prior to pulping. Results from exp...
متن کاملAnaerobic Xylanolytic Bacterium from Decayed Pinus patula Wood Chips
An anaerobic, mesophilic, sporeforming, xylanolytic bacterium was isolated from decayed Pinus patula wood chips. The cells of this organism were gram-negative rods, had peritrichous flagella, and formed terminal round endospores which distended the cell wall. Xylan, cellobiose, fructose, glucose, maltose, mannose, melezitose, raffinose, rhamnose, salicin, sucrose, and xylose were utilized. The ...
متن کاملEffect of rice straw and wood chips on Soil erosion and seedling growth on the fill slope of forest roads
Extended abstract 1-Introduction Erosion is a geomorphologic and natural process that is always seen across the world, but this process is triggered by human activities, such as road construction, resulting in a significant negative impact on water resources, soil, environment and national economy. According to the above, preventing soil erosion is an important target in the management and...
متن کاملAssessment of wood-inhabiting Basidiomycetes for biokraft pulping of softwood chips.
Wood-inhabiting Basidiomycetes have been screened for various applications in the pulp and paper industry and it is evident that different fungi need to be used to suit the specific requirements of each application. This study assessed the suitability of 278 strains of South African wood-decay fungi for the pre-treatment of softwood chips for kraft pulping. The influence of these fungi on kappa...
