SELLATAN®
PA liq Ecological Pickle Acid for Low Salt Pickling
In various parts of the tanning world the demand for reduced salt in
tannery waste water has grown steadily. TFL responded by working with
several major tanneries in the Arzignano area, and as a result SELLATAN®
PA liq was developed as part of a complete pickling, tanning and basifying
system which allows a substantial reduction in the salt used in pickling.
For wet-blue production the system also enables the tanner to use reduced
amounts of chrome tanning and basifying agents, without changing the character
of the final article. The result is a reduction of about half of the chloride,
a third of the sulphate and half of the chromium in the spent tanning
and final washing floats.
A halving of the salt used in the pickle of chrome-free, aldehyde tanning
is also possible.
SELLATAN® PA liq is based on modified polysulphonic
acids and is a further development of the well known SELLATAN®
P liq, which has been sold successfully for many years as a non-swelling
pickle acid. The new version also has some tanning effect and therefore
allows pickling to be carried out at a few degrees higher than normal.
Importantly, it provides a faster and more uniform penetration of subsequently
applied tanning agents and, it noticeably improves tensile strength.
As a part of the TFL ECO Solution, the product contains no potentially
harmful substances, thereby making it suitable for the TFL White Line?
System.
