Butea monosperma as a lignocellulosic raw materials was collected from the campus of Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Chemical raw material namely phenol, formaldehyde and sodium hydroxide were used for the preparation of phenol formaldehyde resin and paraffin wax, liquid ammonia and stearic acid for the preparation of wax emulsion as sizing agent. The boards were prepared from different PF resin content i.e. 8, 9, 10, 11 and 12 per cent with 0.5 and 1.0 per cent wax emulsion. Physical properties were examined by testing the boards as per the procedure laid down in IS: 2380 and IS: 3087.en_US
dc.description.abstractThe present investigation entitled, “Assessment for the suitability of Butea monosperma Lam. for preparation of particle board” was carried out during the year 2016-2018 at Department of Forestry, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The study was carried with the objective to study the suitable percentage of PF resin content for the preparation of particle board and to evaluate the physical properties of particle boards. Butea monosperma was collected from the premise of Dr. Panjabrao Deshmkukh Krishi Vidyapeeth Akola as a lignocellulosic wood raw material and phenol formaldehyde resin as a binder and wax emulsion as sizing agent was used for preparation of particle board. The particle boards were prepared from 8 to 12 per cent PF resin content with 0.5 and 1 per cent wax emulsion. Physical properties were examined as per the procedure laid down in IS: 2380 and IS: 3087. Thickness of the board varied from 8.7 to 9.9 mm while, moisture content varied from 7.5 to 9.6 per cent. Maximum thickness and moisture content was recorded in the board prepared with 8 per cent PF resin content whereas, minimum thickness and moisture content was observed in the boards prepared from 12 per cent of PF resin content with 1 per cent wax emulsion. Density of the particle board varied from 0.72 to 0.86 g/cm3. Maximum density was recorded in boards prepared from 12 per cent of PF resin content with 1 per cent wax emulsion whereas, minimum density was recorded in boards prepared from 8 per cent of PF resin content. Water absorption test of the boards for 2 hours and 24 hours soaking in water varied from 20.72 to 58.74 per cent and 42.34 to 82.95 per cent, respectively. Boards prepared form 10 per cent PF resin content with 0.5 per cent wax emulsion, 11 and 12 per cent PF resin content with 0.5 per cent and 1.0 per cent wax emulsion met the requirement of IS specifications. Increase in the amount of PF resin with addition of wax emulsion showed decrease in water absorption property. Highest value (0.46 %) of length swelling was recorded in the boards prepared with 8 per cent PF resin content and lowest (0.18 %) in the boards prepared from 12 per cent PF resin content with 1 per cent wax emulsion. The values obtained for length swelling of all the boards prepared from different PF resin content met the requirement of the IS specification. Maximum thickness swelling of 24.64 per cent was recorded in the boards made from 8 per cent PF resin content and minimum value of 5.74 per cent in the board made from 12 per cent PF resin content with 1 per cent wax emulsion. The values reported for thickness swelling of the board prepared from 10 per cent PF resin content with 0.5 per cent wax emulsion,11 and 12 per cent PF resin content with 0.5 per cent and 1.0 per cent wax emulsion met the requirement of IS specification. Swelling due to surface absorption after 2 hours ranges between 06.09 to 24.46 per cent. The maximum swelling due to surface absorption was observed in the board prepared from 8 per cent PF resin content and minimum swelling due to surface absorption was observed in the board prepared from 12 per cent PF resin content with 1 per cent wax emulsion. The values obtained for swelling due to surface absorption decreases as amount of PF resin increases with addition of wax emulsion. Satisfactory boards were prepared from 10 per cent PF resin content with 0.5 per cent wax emulsion, 11 and 12 per cent phenol formaldehyde resin with 0.5 per cent and 1.0 per cent wax emulsion met the requirement in respect of physical properties as specified in IS: 3087 (1985).en_US
