Customized PVC Board Salt Spray Test Chamber with Multiple Safety Protection Device ISO9227

Plastic Board Salt Spray Corrosion Testing Chamber With Multiple Safety Protection Device

Brief Introduction:

The salt spray (or salt fog) test is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings. Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.

Salt spray testing is an accelerated corrosion test that produces a corrosive attack to coated samples in order to evaluate (mostly comparatively) the suitability of the coating for use as a protective finish. The appearance of corrosion products (rust or other oxides) is evaluated after a pre-determined period of time. Test duration depends on the corrosion resistance of the coating; generally, the more corrosion resistant the coating is, the longer the period of testing before the appearance of corrosion/ rust.

The salt spray test is one of the most widespread and long established corrosion tests. ASTM B117 was the first internationally recognized salt spray standard, originally published in 1939. Other important relevant standards are ISO9227, JIS Z 2371 and ASTM G85.

Acidified Salt Fog Test (cyclic) can be used to test the relative resistance to corrosion of aluminium alloys when exposed to a changing climate of acetic acid salt spray, followed by air drying, followed by high humidity, all at an elevated temperature.

This test is also referred to as a MASTMAASIS test. Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises the following 3 part repeating cycle. 0.75 hours exposure to a continuous indirect spray of salt water 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 2.0 hours exposure to an air drying (purge) climate. This is followed by 3.25 hours exposure to a high humidity climate which gradually rises to between 65%RH and 95%RH. The entire test cycle is at a constant chamber temperature of +49C. 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℃.
