HayWHNKN 270L Salt Spray Testing Chamber Salt Fog Corrosion Test with Cycle Timer for Laboratory Salt Water Spray Testing Machine Salt Fog Coating

HayWHNKN 270L Salt Spray Testing Chamber Salt Fog Corrosion Test with Cycle Timer for Laboratory Salt Water Spray Testing Machine Salt Fog Coating

【Scope of Application】The salt water spray testing machine is used for various materials surface treatment, including coating,electroplating,organic and inorganic skin film, anodic treatment, anti-rust oil and other anti-corrosion treatment to test its corrosion resistance. 【Cycle Time Can Be Set】This type salt spray tester have timing function, it has 2 timers and you can set a cycle time. 【High Efficiency】The heating tube is made of high corrosion resistance titanium tube).Adopt the direct heating method, the heating speed is fast to reduce the standby time,accurate temperature, less power consumption. 【Even Mist Spraying】Adopting bernoute principle to absorb brine and then atomize.The glass nozzle is hidden in a tower tube which is connected with a tapered diffuser. The mist is sprayed from the diffuser to make sure the mist will falls on the test piece even.No blocking phenomenon of crystallization, can ensure the standard of continuous test. 【Real Time Display】The salt spray machine has a pressure gauge to show the pressure inside the chamber so You can always adjust the chamber pressure.Intelligent control panel with digital display.the corresponding indicator will light up when a fault occurs. All equipment needed in the test: Spray nozzle, salt water barrel, test piece support, spray liquid collection container, test chamber, salt water, supply tank, pressure tank, supply equipment and exhaust equipment required for compressed air, the device is shown in Fig, and test as followed.
Blunt material is required, it is required that the material itself cannot be corroded, and it can not affect the corrosion test.
The fog nozzle cannot spray the test liquid directly to the sample , the solution at the top of the spraying chamber cannot drop on the test piece.
The test liquid dropped from test piece cannot flow back to the salt bucket again for the test.
The solution should not contain grease and dust, so you have to prepare an air cleaner.
The level area of the spray taking device is 80 cm2, the diameter is about 10 cm. Put the spray taking device beside the test piece.
Spray liquid should be collected at least 16 hours, an average per hour can be collected 2ml to 1ml solution. Use the final average to represent the amount of spray.
The concentration of the Sodium Chloride Solution should be maintained at 40~60g/L.
The temperature of the pressure barrel should be kept in 47+1 degree, temperature of the brine barrel should be kept in 35+1 degree.
The machine have timing function, and you could set time to open or close automatically.

This product is used to test the corrosion resistance of the electrodeposited coating of many kinds of metallic materials.
