RANCANG BANGUN ALAT KEMPA HIDROLIK (PENGARUH KOMPOSISI, TEKANAN DAN SUHU TERHADAP SIFAT FISIK PAPAN PARTIKEL)

Abstract

Along with the times, the need for furniture is also increasing, where the use of wood is also increasing. However, the availability of wood is increasingly limited and the high demand for furniture will require alternative raw materials for wood. One alternative offered is a particle board made from a mixture of empty bunches of palm oil and wood powder. In the manufacture of particle board requires technology in the form of press to press and print wood powder that has been mixed with adhesive at certain temperatures and pressures. This press tool for printing particle boards works with the compressive force generated from the hydraulic pump. The purpose of this study was to design a press with high pressure-suppressing components to produce a particle board measuring 20 cm x 5 cm x 1 cm and will be tested based on JIS A 5908 - 2003 in the form of density, moisture content, thickness development, water absorption capacity and the modulus is broken. The Hydraulic Press Tool is capable of operating up to a maximum pressure of 3 tons, a maximum temperature of 400℃ and a heating speed of 3℃/minute. The resulting fracture modulus of the particle board did not meet JIS A 5908 - 2003. The best particle board was particle board using adhesive Polychloroprene with a composition of 60% adhesive, 24% OPEFB and 16% teak wood powder, with operating pressure of 30 MPa and temperature of 150℃ where the value of density, water content, density and water absorption is 0.39gr/cm3 ; 8.4%; 7%; 85.4%
