Reaction between process chemicals and soiling
Problem
Natural oils and fats can be emulsified with
alkaline process chemicals. This can lead to
a heavy build-up of foam.
Soiling containing high protein levels, such
as blood, can cause a heavy build-up of
foam when processed with alkaline process
chemicals.
Non-precious metals such as aluminum,
magnesium, and zinc can release hydrogen
when processed with very acidic or alkaline
process chemicals (oxyhydrogen reaction).
