Rasvaärastamine

Rasvaärastamine, also known as degreasing, is a process used to remove oil, grease, and other lubricants from surfaces. This is often a crucial preliminary step in manufacturing, maintenance, and cleaning operations. Various methods are employed for rasvaärastamine, depending on the nature of the surface, the type of contaminant, and the desired outcome.

Common rasvaärastamine techniques include solvent degreasing, where organic solvents dissolve the greasy substances. Water-based degreasing is another approach, often utilizing alkaline cleaners or detergents to emulsify and lift the oils. Steam degreasing is effective for removing heavy grease buildup through high-temperature steam. Mechanical methods like wiping or scrubbing with absorbent materials can also be used for less severe contamination.

The importance of effective rasvaärastamine lies in its ability to prepare surfaces for subsequent treatments. For instance, in metal fabrication, degreasing ensures proper adhesion for coatings, paints, and welding. In the food industry, it's vital for hygiene and preventing contamination. In automotive and machinery repair, it allows for accurate inspection and repair of components. Improper or insufficient rasvaärastamine can lead to defects, reduced performance, and safety issues. Environmental regulations also play a significant role in the choice of rasvaärastamine methods, often favoring less hazardous solvents and more efficient, closed-loop systems.
