Ink Sludge: Solid Residue Reused in Acoustic Conditioning of Celta Units in GMB - Gravataí, RS

The ink sludge is a residue originating of the painting process. In this work, it sought to study reuse of this sludge of Celtic automobile units ink of the company General Brazil's Motors (GMB), located in Gravataí-RS, as part of the blanket anti-noise load composition to be employed in the body structures of these automobiles. The importance use of the ink sludge goes to the encounter of the sought options, nowadays, for the reduction of the environmental impact provoked by the solid residues. It is known that there is a great quantity of this available material in the painting processes, and that its destination in industrial earthworks can provoke environmental risks, besides generating an additional cost for the industries producers of this residue. With base in this, it accomplished this research, preparing samples with addition of 10%, 20%, 30% and 40% of ink sludge to the components of the original blanket anti-noise by calendering method for cold. Then they were accomplished physical, thermal and mechanical rehearsals, in order to establish a comparison among samples results with increase of ink sludge and the of the blanket anti-noise nowadays used by GMB, aiming determine reuse viability of the sludge for noise conditioning.
