Pemanfaatan Silika Abu Sekam Padi sebagai Bahan Pengisi Rubber Membrane Filter Press untuk Memisahkan Minyak Inti Sawit

Abstract

This research was aimed to obtain rubber membrane filter press (RMFP) from natural rubber (NR) as well as synthetic rubber (chloroprene rubber and nytrike butadiene rubber). The research method was done my vulcanizing natural rubber, synthetic rubber, and filler to shape RMFP. Research formulation was done with 8 units of experiments using variations of mixers that have been pre-determined. The examination to the RMFP was done with ASTM test methods that cover parameters such as viscometer mooney, hardness, tensile strength, and modulus 200%, elongation at break, tear strength, density, and abrasion. The laboratory results showed that the formula for RMFP D that is contained of the mix of NR 10, CR 90, A 86 2 phs; steararatic acid 0.5 phr; TMTD 0.2 phr; sulfur 0.5 phr; ETV 0.8 phr; dan Mo 3 phr with results for hardness 81.5 shore A, tensile strength 161.5 kg/cm2, modulus 200% 41.50 kg/cm2, elongation at break 831%, tear strenght 97.50 kg/cm2, density 1.604 g/cm3, abrasion rest 280.5 mm2, curing characteristic rheometer on temperature 150 oC 12.484%
