Scope of application
With the rapid development of modern industrial technology, the application fields of all kinds of electronic and electroplating products are becoming more and more extensive, and the environmental conditions are becoming more and more complicated.Only by reasonably specifying the environmental conditions of the product and choosing the environmental protection measures of the product correctly can the products be protected from damage in the storage and transportation and safe and reliable in the process of use.Therefore, it is necessary to carry out artificial simulation environment test for materials or products to ensure its high quality.Artificial simulation environment test is a scientific generalization of the actual environmental impact, which has the characteristics of typicalization, standardization, convenience for use and convenience for comparison.The diversity of environmental conditions and the importance of environmental testing have also put forward stricter requirements for environmental testing equipment.
The salt spray test is a kind of artificial simulated salt spray environment. Compared with the exposure test in atmospheric conditions, it has obvious advantages: the corrosion environment can be controlled and the environmental reproducibility is good.The test time is obviously shortened.It saves a lot of manpower, financial resources and material resources.It has been developed and popularized very quickly, and has been developed from the initial simple neutral salt spray test: acetic acid salt spray test, copper salt accelerated acetate fog test and alternating salt spray test.
The equipment can reach any temperature point between normal temperature and 55 degrees in the test working space and maintain constant.Salt spray corrosion test for materials or products under constant temperature and relative humidity in the specified volume.
The materials used to make the equipment are imported corrosion resistant PP plastic sheets, which do not react with saline solution or acidic saline solution, and do not affect the test results.The internal and external pressure balance of the equipment is designed, the salt mist is free to settle in the box, and can be adjusted to the national standard.In addition, the design takes into account the top of the equipment, the inner wall and other parts will have condensed water, which will affect the test results if it drops to the test sample.So of this equipment is designed to be 106 ° included Angle, thus, this equipment is in the process of test, the condensed water will not affect the test result onto the samples.
