Project Description

salt spray chamber

Salt Fog Test Chamber | Salt Mist Test Chamber China Manufacturer & Supplier

Salt Spray Chamber is also known as the salt fog test chamber, which belongs to a widely used environment simulation chamber. It is used to simulate the salt fog environment to determine the corrosion resistance of materials treated with coating, electroplating, anodizing, anti-rust oil and anti-corrosion varnish, etc.

The salt mist chamber was born to help people in measuring corrosion resistance of solid substances to figure out countermeasures to extend the service life or minimize the negative impacts.

The salt spray test equipment can be divided into electronic salt spray test chamber, touch-screen salt spray test chamber and compound salt spray test chamber.

Test Principle

Saline water with a 5 ± 1 % concentration by weight is absorbed and atomized uniformly based on Burnoult’s principle. Salt mist is a dispersion system composed of tiny droplets containing salt with a specific concentration, which is harmful to materials that are sensitive to sodium chloride in nature. The specimen is exposed to the testing zone at the given temperature for a specified time. The test result is evaluated via visual inspection.

This Salt Mist Chamber is applicable to salt spray testers include neutral salt spray test (NSS), acetic acid spray test (AASS) and copper-accelerated acetic acid salt spray test (CASS).

touch screen salt spray chamber

Touch-screen Salt Spray Test Chamber

Compared with the physical buttons used in the electronic salt spray test chamber, this touch-screen salt spray test chamber uses a large high-definition touch screen as the control panel, which looks more fashionable and advanced in technology. It integrates various control functions. The user only needs to click on this screen to set multiple parameters of the test quickly.

It is configured with a 7-inch touch screen controller, matching with a PCL system for facilitating the fixed-value test (continuous spray) or programmable tests (intermittent spray, cyclical spray). One device can achieve multiple functions to meet the different requirements for salt spray determination. This instrument features a high-precision temperature control module, PID automatic calculation to control temperature, and a high stability platinum temperature probe.

This equipment uses an automatic / manual water filling system so that the testing will not be interrupted. The method of direct heating by steam is used in the salt spray test, which has a fast heating speed and uniform temperature distribution to reduce the standby time. Defog function is avaialble. This Chamber is equipped with dual over-temperature protection, low water level protection, overload short circuit protection and so on.

Compound Salt Fog Test Chamber

The compound salt spray test chamber is an upgraded version of the touch-screen salt spray test equipment. It has the function of alternating temperature, humidity and heat based on temperature and humidity adjustment. It is used to test various performance indicators and quality management of samples under alternating compound conditions such as high temperature, damp heat, dryness, and salt spray.

This chamber uses a 7-inch high-definition touch LCD, which supports the preset of the test program. The program mode can set salt spray and humidity test at the same time, and the machine can be used to perform common alternating salt spray test, dry and wet compound salt spray test, or independently perform NSS test, AASS test, CASS test, damp heat test, and dry test. The heating and cooling of this machine can be in rate control, and it has the function of correcting the reference point of temperature and humidity. The humidification and dehumidification systems are completely independent. It is equipped with an automatic water replenishment system, which automatically completes replenishment when the water level is too low, and it also can use manual water replenishment. Its time setting range is as long as 999 h 59 m, with a power-off memory function, and it can continue to execute the remaining programs when power is restored.

In order to ensure the cooling rate and minimum temperature requirements of the chamber, this machine adopts a compressor refrigeration system, which includes a compressor, radiator, evaporator and throttling device, etc. The heat exchange is realized through an evaporative condenser.

How Does Salt Spray Chamber Work?2021-06-24T13:40:31+00:00
  1. Check all parts in place, plug in the power and air source, and adjust the inlet air pressure to 0.2 MPa.
  2. Turn on the “Power” switch, 3 indicator lights representing Spray Chamber / Salt solution / pressure barrel will be on, which means water shortage of these areas respectively. Pour the clear water into the spray chamber and pressure barrel until the lights are off.
  3. Prepare a salt solution to be used, which shall be prepared by dissolving 5 ± 1 % by weight of salt in 95 ± 1 % by weight of distilled or demineralized water, then fill the brine container from the reagent entrance with the solution until the light is off.
  4. Add water in the groove in contact with the cover to form a water seal to prevent droplet leakage.
  5. Switch on the “Operation” button, set the temperatures of spray chamber & pressure barrel (the temperatures of both on our salt spray test machine are already set to be at 35℃ and 47℃ according to relevant specifications in the factory, operators don’t need to set them again in use).
  6. Put the specimen racks in the chamber one by one to accommodate the test pieces reasonably.
  7. Lay down the plastic cover and turn on the “Spray” button, pull out the pressure regulating valve and turn it clockwise to regulate spray pressure to 0.1 MPa.
  8. The salt mist chamber starts to work (the length of the spray tower is adjustable based on practice).

The above is just for reference. It is not suitable for all types of salt spray chambers. Please strictly follow the procedure of the applied standard to carry out the test when you get this testing machine.
