Chemical processes and technology
Chemical agents
Problem
The ingredients in chemical agents
have a strong influence on the longevity
and functionality (throughput) of the
dispensing system. The dispensing
system (hoses and pumps) should be
set up for a particular type of chemical
agent.
General types:
– alkaline to pH neutral products,
– acidic to pH neutral products,
– hydrogen peroxide.
Chemical agents can damage
elastomers and plastics in the machine
and accessories.
The following oxidising chemical agents
can damage elastomers (hoses and
seals) and plastics in the machine:
– nitric acid,
– peracetic acid,
– products contain active chlorine.
The following chemical agents can
release large amounts of oxygen:
– hydrogen peroxide,
– peracetic acid.
