Explain the development process of the salt spray test chamber
The salt spray test chamber is suitable for the salt spray corrosion test of parts, electronic components, metal materials, and industrial products. It is one of the "three protection" (humid heat, salt spray, mold) test equipment for artificial climate environment. Machinery, national defense industry, light industry electronics, instrumentation and other industries are an important test equipment for various environmental adaptability and reliability. Compared with the exposure test under atmospheric conditions, it has obvious advantages: the corrosion environment can be controlled, the environment reproducibility is good, and the test time is significantly shortened.
With the rapid development of modern industrial technology, the application fields of various electrical, electronic, electroplating and other products are becoming wider and wider, and the environmental conditions they are experiencing are becoming more and more complex and diverse. Only by properly planning the environmental conditions of the product and selecting the environmental protection measures of the product correctly can the product be damaged during storage and transportation, and be safe and reliable during use. Therefore, it is necessary to ensure the high quality of materials or products when performing artificial simulated environmental tests. The artificial simulated environmental test is a scientific summary of the actual environmental impact, and has the characteristics of typicalization, standardization, convenient use, and easy comparison.
The salt spray test chamber utilizes a salty solution or an acidic salty solution to accelerate the corrosion of materials or products under a certain temperature and relative humidity environment, and reproduce the degree of damage suffered by the materials or products within a certain time range. The origin of the salt spray test chamber is to save a lot of manpower, financial resources, and material resources in the research of machinery, defense industry, light industry electronics, instrumentation and other industries. Its development and promotion are very fast, and it has developed from the initial simple neutral salt spray test to: acetate salt spray test, copper salt accelerated acetate salt spray test and alternating salt spray test.
