Equipment Overview For Salt Spray Test Chamber:


This salt spray test chamber is designed and manufactured according to IEC 60068-2-11-1981, ISO 9227-2006, and etc.

This chamber is designed to test the corrosion resistance of the products on the surface of various materials after anti-corrosion treatment such as paint, coating, electroplating, anodic treatment, anti-rust oil, etc.

This chamber sprays the test solution of sodium chloride solution on the test workpiece in mist form to observe its corrosion resistance.

Maintenance For Salt Spray Test Chamber:


1. If the test period exceeds 1 month, please replace and clean the water in the heating tank.

2. If the saline solution used in the test has not been used for more than a week, please do not use it again to avoid affecting the test results.

3. If the time interval of the test is longer, please clean the inside of the test room after the test is completed, and drain the water in the heating tank.

● Drain the water in the heating tank - open the drain valve

● Isolate the water discharge in the sink - pull out the middle silicone plug

● Drain the water in the preheating tank - pull out the inner silicone plug


Structure For Salt Spray Test Chamber:


1. External structure of the test room

Measuring barrel: Collect the spray volume of each test, with a scale of 50ml each time.

Isolation tank: Use the principle of water sealing to avoid leakage of salt mist.

Saturated air barrel: Placed at the bottom of the control box, it is airtight and made of SUS#304 stainless steel plate. Its function is to heat and humidity the air through this barrel, so that the air reaches saturated humidity and then sprays to the nozzle.

Salt water replenishment bottle: Automatically replenish the salt solution in the salt water preheating tank.

Test cover: Roof-type beveled 100-degree perspective cover, used to cover the top of the test room and combine as a whole.

Regulating valve: This valve is adjusted by the display of the pressure gauge when the air pressure is too high or too low. The test room bar is 1Kg/cm2.

Pressure gauge: The pressure displayed by the pointer of this gauge is the pressure achieved when the air is heated through the saturated air barrel and conveyed to the nozzle. The test condition is 1Kg/cm2.

2. Internal structure of the test room

Spray tower: The built-in glass nozzle is placed inside the nozzle, and the spray is guided through the tower tube and then dispersed into the test chamber through the conical disperser.

Spray regulator: Adjust the size of the spray volume, increase the spray volume to increase, and decrease the spray volume to decrease. The brine preheating tank is located at the bottom of the spray tower. The brine in this tank is injected into the preheating tank through the brine supplement bottle. The water level of the preheating tank is controlled by a floating ball, which can automatically control the water level. The drain outlet for cleaning at the bottom of the tank is controlled by a silicone plug.

Collector: The amount of falling mist sprayed from the nozzle falls into the 80cm2 funnel cup in a free fall manner, and then flows into the measuring cup through the conduit.

Storage rack: This rack is made of plastic steel, so the weight of the centralized point should not exceed 2Kg. If it is scattered, it can bear less than 10Kg. There are two rows of round holes on both sides of the rack, which are used to place the rods at vertical angles of 15 degrees and 30 degrees.

Filter: used to filter impurities in salt solution, glass filter.


Heating water tank: This water tank is attached to the bottom of the laboratory and is used to hold water and heat it to keep the temperature of the test room stable. Its function is heating and heat preservation.
