In aqueous solution, the degreasing mechanism by dissolution is replaced by a mechanism for dispersing greases and soiling. This phenomenon is brought about by organic elements called surfactants. These products lower the surface tension by adsorbing at the interface of the bodies in presence. The result is a decrease in the binding forces and a stabilization of the phases of the solution.
BONDERITE® surfactants have emulsifying properties vis-à-vis unsaponifiable fats. The first known surfactant was soap consisting of a carboxylic fatty acid neutralized by soda.
3 types of surfactants are used :
- Anionics: for tempered emulsifying bath. They are foaming.
- Non-ionic: for spray bath because not foaming above the point of trouble of these surfactants.
The point of trouble corresponds to a reversible insolubilization of the compound at a given temperature. This temperature limits the maximum efficiency range with a minimum foaming power.
The start-up of a spray washing machine at a temperature lower than the point of trouble leads to the formation of abundant foam (refer to the product data sheet to determine the optimum temperature). The surfactant thus strengthens a degreasing bath or completes the mineral part of the bath if bi-components.
- Cationics: used mainly in defoamer function.
