The product of ceiling plate-Bar from base bark of physic-nut by phenol-cyanate

Abstract

The objective of this research is to produce the T-Bar. The mixed Gule Phenol-cyanate to made ceiling Plate-Bar plate from the agriculture process’s waste. The researcher brought physic nut plant to produce T- BAR plate for interior building. It was tested based on Thailand industrial standard (TIS 876-2547) for determination of moisture content, density, absorption and expansion when soak in water, as well a cohesion and perpendicular surface tension , flexural resistance and modulus of elasticity . at The results show that suitable size material should not thicker than 2 centimeters. The experiment of ratio between physic nut plant and phenol cyanide resin at 90:10 and 92:8. It was found that suitable proportion of physic nut pant and phenol cyanide resin was 92:8. The temperature used for compression was 120o C. The appropriate density prior to the compression plate was 0.80 g/cm.3 The average moisture content of materials before compression was 8.88%. The suitable compression was 151 lb/in?. The moisture content of the product was 7.64%, The density was 0.818 g/cm.3 The expansion value after soaking in water for 2 hours was 8.02%, and water absorption was 14.22%. Inner bond was 0.55 MPa. Flexibility was 22.44 MPa., and mordulus was 2112MPa.The result of testing complied with the Thailand Industrial Standard (TIS 876-2547).It was concluded that physic nut plant can be used as raw material to make T- Bar plate for interior building
