Metallbearbeitungs- flüssigkeit aus dem Recycling von Polyurethan

The specialized book "Metalworking Fluids from the Recycling of Polyurethane" offers a comprehensive examination of the possibilities for recycling polyurethane waste products. Through innovative processes such as the glycolysis of polyurethane with polyethylene glycol of varying molecular weights, a sustainable approach to the production of metalworking fluids is pursued. The study addresses the hydrolysis of vegetable oils to obtain fatty acid mixtures and the subsequent esterification with various fatty acids. The authors present detailed formulas for the metalworking fluids that result from the combination of distilled water, vegetable oils, and emulsifiers. Additionally, the tribological properties of the produced fluids are thoroughly analyzed, including corrosion inhibition, viscosity, and emulsion stability. This book is aimed at professionals and students in the fields of chemistry, materials science, and mechanical engineering who are interested in sustainable solutions in metalworking.
