Salt Spray Tester

Use:

This machine has a standardized test method to check corrosion resistence of coated samples. Salt spray test is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability in use as a protective finish. The appearance of corrosion products (oxides) is evaluated after a period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion. Different coatings have different behaviour in salt spray test and consequently, test duration will differ from one type of coating to another.

Salt Spray Tester

Material：

1.Test room uses P.V.C (polrvinyl chloride) plate，thickness5 mm，heat-resistant can reach to 80℃。

2.Sealed cap of test room uses imported organic glass，Thickness is 5mm，heat-resistant can reach to 80℃。

3.Reagent replenishing bottle uses hidden water level perspective window,easy to clean,hard to broke down.

4.Saturation air barrel uses platsic and high pressure resistant barrel to make sure heat preservation is good.And match with communicating vessels and cleaning devices.

5.Shelves of test room uses complanate dividing shelf,can adjust the angle freely,spray at all sides,can put many test specimen.

CNS.JIS.ASTM specification

（A） Salt water spray test：NSS , ACSS

（1）Test Room：35℃±1℃

（2）Saturation air barrel ：47℃±1℃

（B） Corrosion resistance test(acidity test)： CASS

（1）Test Room：50℃±1℃

（2）Saturation air barrel：63℃±1℃

Cubage of the brine barrel : 15L

Brine Concentration : 5%

 Air supply system：air pressure is 1kg/cm2 ,separate into 2 stage to adjust

First stage is roughly adjustment,pressure is 2kg/cm2，Second is accurate adjustment,pressure is 1kg/cm2

 Spraying methods：

  • Adopt Bernoulli’s Principle,absorb the salt water and spray,spraying extent is uniform,don’t have blocking and crystallizing function to make sure the continuation testing spray.
  • Nozzle：Use special glass nozzle material,can adjust the size of spraying amount and the angle.
  • Spray amount：1 pcs spray tower is putted in the centre of test room to make sure spraying uniform.It can adjust as 1-2ml  80cm2/hr.
  • Chamber has demisting function,you can see the sample after testing.

 Heating methods：

Adopt direct heating methods,heating speed is quick,can reduce standby time,when temperature is reaching,you can use ON/OFF to change.Temperature can be setted from normal to 70C.

 Control system

1.Test room temperature controller 0-99℃,liquid digit showing with PID  calculation function,controlling error ±0.1℃      1PCS

2.saturated air barrel temperature controller 0-99℃，liquid digit showing with calculation function,controlling error±0.1℃      1PCS

3.Heating trough liquid swelling safe temperature controller 0-120℃  1PCS

4.Saturated air barrel swelling temperature controller0-120℃  1PCS

5.Time showing controller:0.01s-9999hr        1PCS

6.Total Timer 0-9999hr                       1PCS

7.Temperature controlling error(Test Room):±0.1℃

8.Temperature controlling error(Saturation air barrel):±0.1℃

9.Timer showing:0.1s-99990hr.

10.Accumulate total testing time automatically.

11.Showing relative humidity automatically.

Water system：

Adopt water replenishing system,when the water level is too low,it will replenish automatically.
