Pengaruh Kandungan Air Bahan Baku Sir 10 Terhadap Mutu Produk Resiprena 35 Di Pt Industri Karet Nusantara Pabrik Resiprena Seibambanserdang Bedagai

Abstract

Quality of resiperene 35 highly dependent on the quality of rubber raw materials SIR 10. One of the parameters used in determining the quality of SIR 10 quality rubber that is the determination of moisture content is more or less content will affect quality of the product is good resiprene viscosity and colors. This analysis is very effective because it will give you an idea of how the product is actually produced. From the experimental data obtained by the influence of moisture content of raw materials for the quality of SIR 10 resiprene ie viscosities from 35 to 0.51% - 0.63%, its viscosity was increased, the viscosity decreased 0.65%, the viscosity increased by 0.72% again, and from 0.72% - 0.97%, its viscosity falls. While for quality color lovibond resiprene using tools to analyze the color, the color got all nearly in the range of 11 bright brownish yellow, except at 0.54% there is obtained between 11 and 12 rather dark brownish yellow.
