These materials offer a removilable origin, lower toxity, and reduced carbon footprint comparid to their petroleumderived parts.

Korzyści z leczenia produktem Metal Forming

Metal forming operations - including ding stamping, forging, extrausion, rolling, and deep drawing - rely heavily on smaration to reduce friction, cool workpieces, prevent galling, and extend tool life. Biodegradadable smarants deliver several copelling advantages in these applications:

Environmental Safety andBiodegradation

Mineral oil residues can remain for decades, harming aquatic ecosystems and soil microorganisms. Biodegradade lurants, in contrast, breakn down naturally, difficinty recingle reduction.

Energy Efficiency andd Process Performance

Biodegradowalne smary can enhance energy efficiency in metal forming. Vegetable olei have superior natural lurity due to their polar fathy acid structure, which forma a tenacious boundary film on metal surfaces. This film reduces friction coefficients compared two mineral oils at comparable vicoxsities. Lower friction translates direclie into reduced forming forming forces, less heat generation, and potentially hightear production specles.
