The Product of ceiling plate-bar to made from base bark of physic-nut

Abstract

The objective of this research is to produce the T- BAR plate from the agriculture process’s waste. The researcher brought physic nut plant to produce T- BAR plate forint prior building. It was tested based on Thailand industrial standard (TIS 876-2547)which are , Determination of moisture content, density, absorption and expansion when soak in water .For cohesion and perpendicular surface tension and tested for flexural resistance and modulus of elasticity 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. The researcher found that suitable proportion are 92%physic nut pant with 8%phenol cyanide resin. The temperature used for compression was 120 C. The appropriate density to the compression plate was 0.80 g/cm.3 The moisture content of materials before compression was at 8.89% average. The suitable compression was 150 lb/in². The moisture content was at 7.65%, The density is at 0.818 g/cm.3expansion value when soaked in water for 2 hours was at 8.02%, water absorption retain 2 hour is at 14.23%, Inner bond is at 0.56 MPa. Flexibility is at 21.45 MPa., mordulus 2116MPa.Which the result of tested with the Thailand industrial standard (TIS 876-2547).The experiment concluded that we can used physic nut plant as material to make T- BAR plate for interior building.
