Subject:
Ceiba pentandra; Erythrophleum suaveolens; bark; durability; formaldehyde; hardwood; plywood; preservatives; production costs; toxicity; urea formaldehyde
Abstract:
... Ceiba pentandra, a non-durable hardwood, is greatly patronized for plywood production. Urea–Formaldehyde (UF) adhesive-joints of plies are filled with toxic preservative-chemicals to extend their service-lives. These pose environmental anxieties. The strengths of C. pentandra ply glue-lines containing different concentrations of Erythrophleum suaveolens bark-extract/UF- and Fossect 88/UF-adhesives ...

Ceiba pentandra; Milicia excelsa; adhesives; cassava flour; cost effectiveness; durability; hardwood; industry; insecticides; sawdust; urea; urea formaldehyde; viscosity
Abstract:
... Expensive adhesives and preservative-chemicals pose challenges to the wood composite industry. Adhesive-extenders reduce cost and enhance ply-joint bonding strength. Urea Formaldehyde (UF) extender was substituted with Milicia excelsa sawdust to formulate five extender-combinations: A (no sawdust), B (100% cassava flour); C (25% cassava flour, 75% sawdust); D (75% cassava flour, 25% sawdust); E (5 ...

Eucalyptus; bagasse; bamboos; bark; bending strength; biomass; cellulose; durability; mixing; modulus of elasticity; modulus of rupture; ovens; particleboards; raw materials; urea formaldehyde; water content; wood
Abstract:
... The decrease of wood supply leads to find out the alternative raw material for particleboard production derived from non-woody cellulose materials, one of the promising material is sorghum bagasse. However, the strength properties of particleboard manufactured from this biomass tend to be low. This research was to evaluate physical, mechanical and durability properties of sorghum bagasse-particleb ...
