Reaction between chemical agents and soiling
Problem
How to resolve it
Natural oils and fats can be emulsified
with alkaline chemical agents. This can
lead to a heavy build-up of foam.
– Where available use the "OIL"
programme.
– This special programme dispenses
emulsifiers (pH neutral) in the
pre-rinse.
– Depending on application use
de-foaming agents that do not
contain silicone oils.
Soiling containing high protein levels
such as blood can cause a heavy
build-up of foam when processed with
alkaline chemical agents.
– Select a cleaning programme with at
least one short pre-rinse in cold
water.
Non-precious metals such as
aluminium, magnesium and zinc can
release hydrogen when processed with
very acidic or alkaline chemical agents
(oxyhydrogen reaction).
– Please observe chemical agent
manufacturer's instructions.
The following substances when used
with chemical agents can lead to a
heavy build-up of foam during washing
and rinsing:
– flux,
– cooling lubricant, cutting/drilling oil
and emulsions,
– abrasive and polishing agents.
– Depending on application, use
emulsifiers or de-foaming agents that
do not contain silicone oils.
