The salt spray test chamber uses salt spray corrosion to detect the reliability of the respective corrosion resistance of the tested samples. Salt spray refers to the dispersion system composed of salt-containing tiny droplets in the atmosphere. It is a three-proof series of artificial environments. One is that many enterprise products need to simulate the destructive effects of the ocean surrounding climate on the products, so the salt spray test box is suitable. The salt spray test is divided into two types: neutral salt spray and acid salt spray. The difference lies in the standards and test methods. They are called "NSS" and "CASS" tests, which are the most common tests in the artificial three-proof climate. method.
monitor
1. Use the original imported Japanese "Youyikong" brand control instrument, 7-inch high-definition true color LCD touch screen
2. Real-time monitoring (monitoring controller real-time data, signal point status, actual output status)
3. Curve recording function 3.3.1. The controller can store historical data within 600 days (under 24-hour operation, the recording interval is more than 1 min, when the control data is recorded at the same time), and can replay the uploaded historical data curve in the control
4. When the machine is stopped, you can insert a U disk to export or upload data at any time, and the exported files can be viewed on the computer or converted into EXCEL format through the software provided with the machine.
5. The instrument is equipped with a USB port, which can directly drive the micro printer to preview and print through the port (optional)
6. The control adopts P.I.D + S.S.R system co-channel coordinated control
7. With the function of automatic calculation, the temperature and humidity change conditions can be corrected immediately, making the control more accurate and stable
Box structure
The integral molding is welded at high temperature, corrosion-resistant, easy to clean, and no leakage.
The tower spray system is equipped with a salt liquid filtration system, no crystallization nozzles, the salt spray is evenly distributed, and the amount of sedimentation can be adjusted freely.
The lid of the box is made of transparent material to clearly see the test items and spray conditions in the box.
A water-tight structure is adopted between the box cover and the box body, and there is no salt spray overflow.
The circuit control board and other vital parts are fixed in a position that is convenient for inspection and maintenance. The side door is opened with a door lock, which is not only beautiful, but also convenient for maintenance.
Internal structure
1. Spray device: tower sprayer with built-in glass nozzle, the spray is guided by the tower tube and then dispersed in a cone shape, and then diffuses evenly into the entire test room;
2. Adjust the spray volume: increase the spray volume of the cone diffuser on the spray tower, lower it to reduce the spray volume;
3. Collector: The fine mist sprayed by the nozzle settles in a free-fall manner. One or several funnel cups with a surface area of 80cm2 are built-in to collect the salt mist. After condensing into water, it flows through the tube to the metering cylinder outside the box;
4. Heating water tank: The water tank is attached to the bottom of the test chamber, and is used to hold water and heat to keep the temperature of the test chamber stable;
5. Shelf: It is made of plastic steel, and the load-bearing capacity does not exceed 2kg. If it is distributed, it can bear a weight of less than 10kg. There are two rows of round holes on both sides of the shelf. The shelf is placed at a vertical angle of 15 degrees and 30 degrees. use.
