WATER & EFFLUENT TREATMENT

industrial cleaning solvent supplier
Titanium – traditionally associated
with leading edge aerospace
industries is now becoming a
standard in many manufacturing
applications. Alloyed with other
metals the excellent corrosion
resistance, unequalled strength-
to- weight ratio and high
malleability has elevated this
most versatile of metals to
applications including medical,
petrochemical and automotive
component manufacture.
The big question remains –
how do we clean it?
Understandably aerospace remains the critical
benchmark in high integrity surface cleanliness
requirements. Typical methods of testing include
Total Organic Compound (TOC) residue, surface
energy (often measured in Dynes/Centimetre) and
gravimetric analysis. The simplest and most readily
available at modest cost is the use of test inks which
has evolved from the traditional “water break” test
but constitutes a rather more subjective method to
accurately record and document ongoing results.
So, how do we clean it?
The critical question has always been long term viability.
Stress fractures and associated failures remain at the
core of the approvals structure. With the demise of
trichloroethylene, the solvents of choice are clear:
Perchloroethylene is an obvious alternative and remains the solvent
species of choice for many aerospace applications. Of course,
products such as modified alcohols and A111 hydrocarbons will
increasingly be considered but validation can take some time.
Official accreditations are a critical factor in the approval hierarchy
and the overriding demand is compliance with ASTM F945.
Perchloroethylene by Richard Geiss GmbH holds such approvals
and with the demise of brominated solvents the demand for highly
stabilised chlorinated products is assured.
Geiss UK Ltd. is the UK's fastest growing industrial cleaning solvent
supplier and represents market leader Richard Geiss GmbH, Europe's
leading provider of ultra-high purity and highly stabilised aerospace
approved recycled solvents including perchloroethylene.

A full back up and support structure including laboratory facilities,
test kits, stabilisers and TLB Secure-Tainer bunded shipment and
storage containers is available with full training in all aspects of
solvent management.
As machining tolerances become ever more stringent the need for
surface cleanliness is rising accordingly. High level industrial cleaning
always requires the same respect and attention as any other aspect
of the production process but so many manufacturers (many of
whom are household names) consider it to be an “afterthought”.
The dismissal of such responsibilities has often proven to be disastrous.
