Touch Controller Corrosion Salt Spray Chamber for Testing NSS CASS
with Anti Corrosion PVC Shell
Brief Introduction:
Seawater Acidified Test (cyclic) can be used to test the relative
resistance to corrosion of coated or uncoated aluminium alloys and
other metals, when exposed to a changing climate of acidified
synthetic seawater spray, followed by a high humidity, both at an
elevated temperature.
This test is also referred to as a SWAAT test. Test specimens are
placed in an enclosed chamber, and exposed to a changing climate
that comprises the following 2 part repeating cycle. 30 minutes
exposure to a continuous indirect spray of synthetic seawater
solution, prepared in accordance with the requirements of the test
standard and acidified (to pH 2.8 to 3.0) by the addition of acetic
acid.
This spray is set to fall-out on to the specimens at a rate of 1.0
to 2.0ml/80 cm²/hour. This is followed by 90 minutes exposure to a
high humidity climate of above 98%RH. The entire test cycle is at a
constant chamber temperature of +49C (may be reduced to +24 to +35C
for organically coated specimens). The number of cycle repeats and
therefore the test duration is variable
Features:
1, Chamber material is made of P.V.C Sheet, sturdily and will not
be out of shape.
2, Test chamber is heated from five directions to ensure the
temperature is uniformity distributed.
3, Spray nozzle is specially made, enable to spray the salt water
with considerable speed, then falls on the surface of samples.
4, Hot and moist air keeps the humidity in the test chamber
conforms testing request.
5, High precision P.I.D. temperature controller limits the
temperature difference within the range of ±0.1℃.
