PAINT AND COATINGS MANUFACTURING: SOUND DAMPENERS

Solvent-free artificial resin dispersions achieve
flame-retardancy and noise reduction in trains
hen determining train or plane travel comfort, it's not only speed,
comfortable seating and legroom that are important, but also the sounds
- or lack of - that also become paramount.
Passengers who wish to work or rest undisturbed can choose quiet
compartments in trains, where loud speech, mobile phone use and other noisy activities
are prohibited. In order to reduce the structure-borne noise of the rail carriages
themselves and therefore to create the quietest-possible environment inside, many
rolling stock manufacturers use sound deadening tactics.
The metal sheets used in the interior construction of carriages - for cladding for
example - are covered in sound-deadening materials to dampen the noise caused by the
metal sheets. At Griwecolor GmbH, there are two products in the portfolio that have
been developed for this area of application: Griwephon AN2-800 and Griwephon light
AN2-900.
The product range has recently been expanded to include the new Griwephon AN2750/EU,
which is classified as a non-flammable product, class A2, according to DIN
EN 13501-1. All three products are ready-to-use one-component solutions that have
also been tested for fire behavior in accordance with EU rail vehicle standard DIN EN
45545-2. Griwephon AN2-800 and AN2-900 meet the requirement sets R1, R2, R3, R6,
R7 and R17 in the hazard levels HL1, HL2 and HL3 and the three products have a very
high acoustic effectiveness in accordance with DIN EN ISO 6721-3.
" The development of our sound-deadening Griwephon AN2-750/EU is based on the
extensive experience that we have collected with AN2-800 and AN2-900 as well as in
the construction material sector, " says Jörg Grieshaber, Managing Director Technology
and Development at Griwecolor. " With these products, we have gathered decades of
know-how in the noise reduction of rail vehicles and facade elements or windows, which
The
monotonous noise
produced by train wheels on tracks
can make some people sleepy while others
struggle to cut out the noise in order to
sleep or work.
we have benefited from in the further
development with regard to reduced
smoke density and smoke gas toxicity as
well as acoustic effectiveness and flame
retardancy. "
