METALWORKING FLUIDS FOAM CONTROL BASED ON NOVEL SURFACTANTS TECHNOLOGY

Emulsifying metalworking fluids are subject to continuous evolution in order to increase economy and safety growing ecological and safety requirements. Therefore the composition of modern formulation is becoming more and more sophisticated so that great number of usual components is changed for new less harmful components. Nowadays different ethoxylates, fatty acid esters or ether carboxylates can be used in modern formulations (L. Pedisic, 1999). Considering some critical points, this paper is proposed for bringing on solution to prevent foam problems since construction of the metalworking fluid formulation. Experimental Methods: Hand Shake, Recirculation, Hi Speed (Blender) and Ross Milles Test. Technologies: Bench Mark, Dow high foam and Dow low foam Non-ionic Emulsifier for Semi synthetic and Soluble Oil type. Preliminary tests has shown positive results compared with bench mark as ordinary non-ionic emulsifier (3% Surfactant/1:20 fluid dilution).
