Effect
The ingredients of the processing
chemicals have a considerable effect
on the durability and functionality (feed
performance) of the metering systems.
The metering systems (feed hoses and
pump) are normally designed for a
specific type of processing chemicals.
General categories:
– alkaline to neutral pH products,
– acid to neutral pH products,
– hydrogen peroxide.
The processing chemicals can damage
the elastomer and plastic components
of the machine and its accessories.
The following oxidizing processing
chemicals can damage the elastomer
components (hoses and seals) and the
plastic components of the machine:
– nitric acid,
– peracetic acid,
– products containing active chlorine.
The following processing chemicals
can release large quantities of oxygen:
– hydrogen peroxide,
– peracetic acid.
