工場から排出される研磨粉の無公害処理と新しい利用法

Abstract

The advanced treatment for the chips, industrial waste discharged from high speed grinding process (about 80ton/month), was investigated. The research consists of two categories, that is, separation technology of machine oil from chips, and formation blending high polymer. Absorbing power of kerosene for acetone, absorption rate in bubbling layer and residence time in spray tower were measured. Henry's constant and Sh-Re relations were caluclated. Residence time in spray tower of 2m height with three spraying nozzle was measured. Mechanical and heat transfer characteristics of the high polymer blend were obtained. Young's modulus and thermal conductivity increased with increase in the mixing ratio of chips. Comparing the measured results with theoretical model , arrangement structure of chips in high polymer was made clear.
