What is the salt spray test?
The salt spray test is an environmental test that uses artificial simulated salt spray environmental conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories, one is the natural environmental exposure test, and the other is the artificial accelerated simulated salt spray environment test. The artificial simulated salt spray environment test uses a test equipment with a certain volume space—the salt spray test chamber, to artificially use the salt spray environment in the volume space to assess the salt spray corrosion resistance quality of the product. . Compared with the natural environment, the salt concentration of the chloride in the salt spray environment can be several times or several times higher than the salt spray content of the general natural environment, so that the corrosion rate is greatly improved, and the product is subjected to a salt spray test to obtain a result. The time is also greatly shortened. If a product sample is tested in a natural exposure environment, it may take 1 year to corrode, and in a simulated simulated salt spray environment, as long as 24 hours, similar results can be obtained. The KOMEG series salt spray test chambers produced by Keming Technology are all controlled by computer. They are self-developed software and have a good operation interface, which makes the operation and monitoring of users more simple and intuitive. Keeping functions can make you run the program. Keeping it in the current state, you can temporarily change the value of this block and automatically follow the set value.

Piston seal is a kind of seal used to seal between piston and cylinder, usually used in hydraulic system and Pressure system. The piston seal can prevent liquid and gas leakage, and also prevent external impurities from entering the system, thus maintaining the normal operation of the system.
Piston seals can be classified based on their structure and material. According to different structures, piston seals can be divided into unidirectional seals and bidirectional seals. A unidirectional seal can only prevent the leakage of liquid or gas from one direction, while a bidirectional seal can prevent the leakage of liquid or gas from both directions. According to different materials, piston seals can be divided into rubber seals, polyurethane seals, polytetrafluoroethylene seals, etc.
In hydraulic systems, piston seals are typically used to seal hydraulic cylinders and pumps. The piston seals in hydraulic systems need to have characteristics such as high temperature resistance, corrosion resistance, and wear resistance to ensure long-term stable operation of the system. In Pressure system, piston seals are usually used to seal cylinders and pumps. The piston seals in the Pressure system need to be resistant to high pressure, low temperature, wear and other characteristics to ensure the normal operation of the system.
In addition to hydraulic system and Pressure system, piston seals can also be used in other industrial fields, such as automobile, aviation, machinery, etc. In the automotive industry, piston seals are commonly used in engines to ensure normal engine operation. In the aviation industry, piston seals are commonly used in the hydraulic system of aircraft to ensure normal takeoff, landing, and flight. In the field of machinery, piston seals are commonly used in hydraulic and press machines to ensure the normal operation of the machine.
