Antiblokkerende

Antiblokkerende is a term used to describe a property or mechanism that prevents or reduces the blocking or sticking of particles or surfaces. In various contexts, this concept applies to different materials and processes. For instance, in the field of plastics and polymers, antiblocking additives are incorporated to prevent layers of plastic film from adhering to each other. This is particularly important for packaging films, where excessive blocking can make the film difficult to open and use. These additives work by creating a microscopic rough surface or by migrating to the surface to reduce the contact area between layers.

Another application of antiblokkerende principles can be found in powder technology. Fine powders, especially in humid conditions, can tend to clump together, forming aggregates that hinder their flowability and processing. Antiblocking agents, often referred to as anti-caking agents or flow aids, are used to maintain the free-flowing nature of powders. These agents typically work by coating the individual particles, creating a barrier that prevents them from bonding together. Examples include silica derivatives, starches, and certain inorganic salts.

The underlying mechanism of antiblokkerende can also be related to reducing friction or adhesion. In mechanical systems, surfaces might be designed or treated to be antiblokkerende, ensuring smooth operation and preventing parts from seizing. This might involve using specific materials, coatings, or surface treatments that minimize intermolecular forces or provide lubrication. The goal is always to maintain separation and prevent unwanted contact or fusion.
