 MANGROVE (RHIZOPHORA RACEMOSE) TANNIN AS ADHESIVE FOR WOOD-BASED PANEL PRODUCTS

 Joseph Fuwape, Amos Oyagade And Anslem Eguanton

 1990

Particleboards and plywood bonded with fortified mangrove tannin were produced from mixed hardwood species. Tests were conducted to determine the bending and internal bond strength, plywood delamination resistance and thickness swelling of the panels. The particleboards and plywood produced from PF fortified tannin met the specification required for commercial boards in Nigeria.

 SUITABILITY OF GMELINA ARBOREA AS DOMESTIC AND INDUSTRIAL SOURCE OF ENERGY

 JOSEPH ADEOLA FUWAPE

 1990

Some combustion related properties, comprising the heating values, stiochiometric air, products of combustion, specific gravity and moisture content of Gmelina arborea samples obtained from three sites in Nigeria were determined. The average gross heating values of the wood was 23.5MJ/kg while the available heating values ranged between 9.75 and 15.78 MJ/m3 of wood. The average oven dry speeific gravity was 0.51 and the average green moisture content was 193%. The combustion and growth characteristics of Gmelina arborea indicated its suitability as fuel material.

 GROSS HEAT OF COMBUSTION OF GMELINA (GMELINA ARBOREA (ROXB)) CHEMICAL COMPONENTS

 JOSEPH A. FUWAPE

 1989

The gross heat of combustion of holocellulose, a -cellulose, lignin and extractives isolated from Gmelina arborea (Roxb) were determined to be 19715, 19704, 25383 and 25137 kJ kg-1, respectively. The bark and leaves which contained relatively high proportions of lignin and extractives had the highest heat of combustion on dry, ash-free basis.

 UTILIZATION OF FOREST AND MILL RESIDUES AS INDUSTRIAL FUEL

 JOSEPH ADEOLA FUWAPE

 1989

The paper reports on the potential for utilization of residues from wood-based industries as sources of energy for production processes. The combustion properties of six common wood species were determined and these were used in estimating the heat energy derivable by burning wood residues accruing from pulp and paper production in Nigeria. It was estimated that 9-4-33-3% of heavy-oil requirements could be replaced by burning wood residues in three Nigerian pulp mills.

 PULP AND PAPER PRODUCTION IN A DEPRESSED ECONOMY: THE NIGERIAN SITUATION

 JOSEPH ADEOLA FUWAPE

 1987

The growth in consumption of pulp and paper in Nigeria and other developing countries is attributed to increase in population, income and literacy level. This paper reviews the world trade in paper products and discusses Nigeria's potential in producing enough paper for consumption and export. Solution to some of the problems militating against optimum production are suggested:

 MATERIAL DEGRADATION: BIODETERIORATION OF WOOD IN USE

 JOSEPH ADEOLA FUWAPE

 1987

Degradation of wood in service is attributed to biological, mechanical and thermal factors. Biodeterioration of wood due to infestation by insects, termites and fungi account for the largest percentage of its degradation in the tropics. This ·study groups fungi that degrade wood into two classes; decay and stain fungi. Decay fungi destroy mechanical properties of wood while stain fungi alter its aesthetic value. Beetles are responsible for the greatest incidences of insect attack while dry wood termite (family Kalotermitidae) account for most degradation by termites to wood in service. Effects of degradation by. various agents are highlighted and methods of control are discussed.

 WOOD AS A MATERIAL FOR THE CONSTRUCTION OF FARM TOOLS AND STRUCTURES

 A. A. Olufayo And J. A. Fuwape

 1987

The preference of wood as material for various constructional purpose is attributed to its availability, workability and adaptability. The paper reviews the utilization of wood in construction of farm tools and structures. The adaptability of lesser known species and methods of their appropriate utilization arc discussed.

 THE NEGLECTED FOREST RESOURCES

 JOSEPH ADEOLA FUWAPE

 1986

This paper outlines the commercial, medicinal and industrial values of some forest resources which are referred to as forest minor products. Forest minor products include herbs, shrubs, tree roots, barks, leaves, flowers and fruits which have been neglected in industrial production of drugs, adhesives and dyes. The use into which specific forest minor products could be put are highlighted. Possible processing techniques are indicated.

 CHECKING DEFORESTATION THROUGH IMPROVED WOOD CONVERSION TECHNOLOGY

 JOSEPH ADEOLA FUWAPE

 1986

Poor log conversion efficiency in Sawmills in Nigeria has been alleged to contribute to the deforestation of the country's forest reserve. A review of studies on log conversion techniques was carried out with the aim of investigating methods of improving log conversion. The report showed that recovery of finished products from log can be improved from 45 - 76% through integrated sawmill technology.

 HEAT OF COMBUSTION AND FUEL VALUE OF GMELINA ARBOREA (ROXB)

 JOSEPH ADEOLA FUWAPE

 1985

Some combustion related properties (the heating value, specific gravity, moisture content and ash composition) of Gmelina arborea (Roxb) obtained from .Jebba (J4) and Awi pulpwood plantations in Nigeria are determined. Tbe average higher heating values for heartwood, sapwood, bark, branch and leaves are 22,542; 24,713; 23,357; 25,114 and 24,544 kJ/kg respectively Variations in heating values were significant only for samples from different sites. The average moisture content of green samples was 193 % (oven dry basis) wbile the average oven dry specific gravity was 0.51. Significant variations existed in the specific gravity and moisture content within a tree and between trees on the same and different sites.
