Salt Spray Chamber Introduction

　　Salt spray chamber　also known as Salt spray tester Salt fog tester　corrosion test chamber　Salt spray corrosion test chamber　Salt spray corrosion test box　corrosion resistance test machine　corrosion resistance performance testing machine

The salt spray chamber is an environmental test that mainly uses artificially simulated salt spray environmental conditions created by salt spray test equipment to assess the corrosion resistance of products or metal materials.

(1) The neutral salt spray test is the earliest and most widely used accelerated corrosion test method. It uses 5% sodium chloride saline solution, and the pH value of the solution is adjusted in the neutral range (6~7) as a solution for spraying. The test temperature is 35°C, and the sedimentation rate of salt mist is required to be between 1~2ml/80cm2.h.

(2) The acetic acid salt spray test is to add some glacial acetic acid to 5% sodium chloride solution.

(3) Copper salt accelerated acetic acid salt spray test is a rapid salt spray corrosion test recently developed abroad. The test temperature is 50°C, and a small amount of copper salt-copper chloride is added to the salt solution to strongly induce corrosion. Its corrosion rate is about 8 times that of the NSS test.

(4) The alternating salt spray test is a comprehensive salt spray test.

High temperature and humidity test

Test temperature: neutral salt spray test: laboratory: 35℃±1℃, b. saturated air barrel: 47℃±1℃, acid corrosion test: laboratory: 50℃±1℃, b. saturated air barrel: 63 ℃±1℃, can also be set according to JIS, CNS and other standards

Salt spray chamber box structure

The salt spray chamber is integrally molded and welded at high temperature, which is corrosion-resistant, easy to clean, and has no leakage.

Salt spray chamber tower-type spray system, and equipped with salt liquid filtration system, no crystallization nozzle, salt spray distribution is uniform, and the settlement amount can be adjusted freely.

The cover of the salt spray chamber is made of transparent material, so that the test items and spray conditions in the box can be clearly seen.

The salt spray chamber adopts a water-tight structure between the cover and the box body, and there is no salt spray overflow.

The circuit control panel and other vital parts of the salt spray chamber are fixed in positions that are convenient for inspection and maintenance. The side cover door with door lock opening is not only beautiful, but also convenient for maintenance.

Add some glacial acetic acid to the sodium solution.

Salt spray chamber operation method

1. Install the internal parts of the salt spray chamber: tower spray device, funnel, round rod, V-shaped sample holder, etc.

2. Connect the air source, after the power is connected, turn on the power switch.

3. Add water to the pressure barrel and the box, stop adding water after the two low water level lights go out, and add water to the sealing groove to seal.

4. Mix pure water and sodium chloride salt at a ratio of 1:20. Pour the prepared solution into the entrance of the reagent (just turn off the low salt water light).

5. After all the lights are off, we can turn on the operation, spray, and timing switches, and the defogging switch can only be turned on after the test is over.

6. According to the test requirements, the equipment has two spraying methods, continuous and periodic (when continuous spraying, T1 and T2 tables are all set to 0, and when intermittent spraying, T1 is set as working time, and T2 is resting time).
