    JY-1043 Salt Spray Chamber



    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.


    1. the spray nozzle the heart of teser adopt  Bo Nute Principle which change saline water into atomization but no crystallization produced.

    2. the controller is digital type microcomputer which delivers precision temparature

    3. parameters show on the display screen such as temparature, humidity, pressure, spray capacity and time.

    4.test specifications are accept worldwild.

    (A)                    Test room uses P.V.C (polrvinyl chloride) platethickness8mmheat-resistant can reach to80℃

    (B)                    Sealed cap of test room uses imported organic glassThickness is8mmheat-resistant can reach to80℃

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

    (D)                    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.

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

        First stage is roughly adjustment,pressure is2kg/cm2Second is accurate adjustment,pressure is1kg/cm2

    7.Spraying methods

    (A)      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.

    (B)      NozzleUse special glass nozzle material,can adjust the size of spraying amount and the angle.

    (C)     Spray amount1 pcs spray tower is putted in the centre of test room to make sure spraying uniform.It can adjust as 1-2ml  80cm2/hr.

    (D)     Chamber has demisting function,you can see the sample after testing.

    8.Heating methodsAdopt 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 to70C.
