Emulsified oil products may exhibit foaming during use. So, what exactly are the causes and associated hazards of this phenomenon? Below, the team at Lingxian Additives provides a detailed explanation of the reasons behind-and the risks associated with-foaming in these products.
First, the base oil itself within emulsified oil products possesses inherent foaming mechanisms, and the additives incorporated into them often contain surface-active substances. During the manufacturing process, foam can form subtly and imperceptibly. Furthermore, during metalworking operations, if residual metalworking fluids or chemical additives remain in the equipment, they may react with the emulsified oil; alternatively, the rapid mixing and high-shear forces present in the processing environment can easily induce foaming within the mechanical equipment.
Second, during the service life of the emulsified oil, the presence of bubbles can compromise the product's performance-specifically by diminishing its rust-prevention, cooling, and lubrication capabilities. This increases operational difficulties, slows down production progress, and drives up costs. Moreover, foaming can negatively impact the effective yield of the emulsified oil; excessive foam generation may lead to overflow, thereby polluting the surrounding environment and resulting in the wasteful loss of raw materials.

Additionally, foaming in emulsified oils increases the liquid-gas contact surface area, which accelerates oxidation and promotes flotation effects. This leads to an uneven distribution of ingredients within the emulsion, causing the product to deteriorate and ultimately hindering its proper and effective application.
The above outlines the primary causes and associated hazards of foaming encountered during the use of emulsified oil products.
