What is the specific function of the accessories of the salt spray corrosion test chamber?

Salt spray corrosion test chamberMainly used to test the salt spray corrosion resistance of products, it is mostly used for corrosion resistance testing of metal products, coating materials, electroplating and other product surfaces.

Salt spray corrosion test chamberIn addition to a non removable complete box body, there are also some necessary accessories. So, what are the functions of these accessories? Shang Shijun will summarize and analyze the following for you today:

1. Glass nozzle: the salt water is atomized by pressure to form spray, which is sprayed from the nozzle;

2. V-shaped sample holder: also used to place test samples, which can be tested at a 15 degree or 30 degree angle;

3. Salt bucket: used forSalt spray corrosion test chamberStore saltwater. Some customers require larger saltwater buckets, the bigger the better, but if they are too large, the saltwater can easily settle and clump, making cleaning difficult!

4. Funnel: used to collect salt solution, with an area of 80 square centimeters, usually two, depending on the size of the test chamber;

5. Measuring cylinder: The funnel collects salt solution and reaches the measuring cylinder through a silicone pipeline. It is an important item to determine whether the salt spray corrosion test chamber meets the standards. One funnel is matched with one measuring cylinder (measuring cylinder);

6. Mist exhaust pipe: used forsalt spray test chamberMist and exhaust gases must be discharged outdoors, otherwise other equipment in your entire room will corrode and shine;

7. Round rods: Generally equipped with 6-8 rods depending on the size of the box, some are made of glass rods, some are made of other high-strength non-metallic materials, and some are made of metal materials but coated with anti-corrosion coatings on the surface (mainly for corrosion). It is used to place sheet-like test samples, and during the test, the samples are laid flat on a round rod to evenly conduct salt spray tests on the surface of the samples;

8. Saturation bucket: heats and humidifies the incoming air and filters the oil;

9. Water: Pure water or distilled water without impurities should be used, as tap water containing impurities can easily clog pipelines;

10. Salt: Industrial salt is required;

11. PH test paper: Of course, it is used to detect the acidity and alkalinity of the working chamber in the salt spray corrosion test chamber. This is very important, otherwise, the pH value of the solution will not be known during acid corrosion testing, and it cannot be too high or too low;

12. Hydrometer: This is mainly equipped with saltwater to ensure a concentration of 5% in the ratio;

13. Pressure gauge: of course, it displays and controls the pressure of spray. The pressure of air compressor or air source is displayed through it;

14. Oil filter: This is mainly used to filter impurities in the air compressor or high-pressure gas source, so as not to block the fragile nozzle;

15. Lid: This is a must-have, some use transparent organic glass panels, while others use PVC door openings for observation windows. Then you know the purpose, which is to facilitate the observation of the product testing inside during salt spray testing;

16. Of course, there are also air compressors or high-pressure gas sources. If you don't have a high-pressure air source, you have to buy an air compressor. It is a necessary equipment to generate spray. You can refer to our technical articles for selection of air compressor and precautions in use (regularly remove water in the air tank);

17. Also, there are several rubber plugs under the lid, which are used for plugging holes and for sealing the box and lid with water. Although the items are small, they must not be lost, otherwise it will be time-consuming and laborious to find them during testing;

18. Measuring cup: usually 5000ml, used for mixing saline solution;

19. What? And the spray tower? That thing is of course used for spraying salt spray. Salt water can only be sprayed into the box through the nozzle on top for corrosion testing. That nozzle is very delicate, please pay attention to cleaning and unclogging. If it gets blocked and you don't want to do it, then come find us to solve it.
