Preface
With the development of modern industrial technology With the rapid development of various electrical and electronic products, electroplating and other products, the application fields are becoming wider and wider, and the environmental conditions they are subjected to are becoming more and more complex and diverse. Only by reasonably specifying the environmental conditions of the product and correctly selecting the environmental protection measures for the product can the product be protected from damage during storage and transportation and be safe and reliable during use. Therefore, artificial simulated environmental testing of materials or products is an indispensable and important link to ensure their high quality. Artificial simulated environmental tests are scientific summaries of actual environmental impacts and have the characteristics of typification, standardization, ease of use, and ease of comparison. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
The salt spray test was first proposed by... The purpose at that time was to obtain test conditions similar to those in the coastal atmosphere to study the reliability of certain metal protective layers. It is to put the sample in salt spray for testing. This is the earliest application of salt spray test. Since 2000, the American National Bureau of Standards has begun to promote and apply the 2011 standard as an interim standard and has revised it many times. It has been listed as an official standard since then.
Since the 1990s, our country has cooperated with the former Soviet Union and other Eastern European countries to carry out product salt spray testing. The subjects of the tests at that time were mainly some military products and some important industrial products. Because my country's industry had just started at that time, salt spray testing work developed slowly. In the 1990s, with the development of the commodity economy, international trade increased day by day. As a testing technology to evaluate the corrosion resistance of products, the salt spray test has been widely used and applied.
The salt spray test is a test that artificially simulates the salt spray environment. It has significant advantages compared with the exposure test under atmospheric conditions: the corrosive environment can be controlled, the environment is reproducible, the test time is significantly shortened, and a lot of manpower is saved. Financial and material resources. Its development and promotion have quickly evolved 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 and other forms. Our country has adopted the salt spray test as a national standard and has made detailed regulations.
This salt spray corrosion test equipment uses salt-containing solution or acidic salt-containing solution to accelerate corrosion of materials or products under a certain temperature and relative humidity environment to reproduce the corrosion experienced by materials or products within a certain time range. destruction level. The equipment can be used to assess the salt spray corrosion resistance of materials and their protective layers and to compare the process quality of similar protective layers. It can also be used to assess the salt spray corrosion resistance of certain products.
The equipment can reach any temperature point from normal temperature to ℃ in the test working space and maintain it constant. Conduct a salt spray corrosion test on materials or products when the temperature and relative humidity in a box with a specified volume are constant. The materials used to manufacture this equipment are corrosion-resistant plastic sheets that will not react with salt-containing solutions or acidic salt-containing solutions and will not affect the test results. During the design of this equipment, the internal and external pressures are balanced and the salt spray settles freely inside the box and can be adjusted to the range specified by national standards. Moreover, the design takes into account that condensation water will be generated on the top, inner wall and other parts of the equipment. If it drips onto the test sample, it will affect the test results. Therefore, the top cover of this equipment is designed at an angle between the left and right, so that condensed water will not drip onto the sample during the test and affect the test results.
Reference standards
This salt spray corrosion test equipment complies with and is applicable to the salt spray test standards promulgated by our country. And the salt spray test standards for electrical and electronic products are used for salt spray test standards for metal coatings, and are specially used for The salt spray test standards for assessing electroplating layers of light industrial products, the salt spray test standards for paint layers, and other standards currently in use internationally regarding salt spray corrosion.

Introduction to structural design
This salt spray corrosion test The box has a beautiful appearance design, reasonable structure, smooth lines, and natural flow. The box material is made of high-quality plastic sheets. The appearance is smooth and bright, corrosion-resistant, easy to clean, and leak-free. Various auxiliary accessories and facilities are also made of corrosion-resistant materials.
The box cover material is a high-quality transparent plate, which can clearly observe the condition of the indoor specimen from the outside without affecting the test results. And the box cover is designed with an optimal top angle so that the mist generated during the test will not drip onto the sample and affect the test results. The salt spray after passing through the test piece falls freely on the bottom of the test chamber and is discharged outdoors along with the waste to ensure that the test solution is not reused. The lid and body of the box are water-sealed to prevent salt spray from overflowing, which may affect test results, corrode other equipment in the room, and even cause harm to test operators. The lid of the large equipment adopts a cylinder imported from Taiwan to automatically open conveniently. (There is no cylinder below /-) The opening angle can also be designed according to the customer's special conditions. The air source can be compressed air. The gas enters the saturated cylinder through the secondary oil-water separator to preheat, humidify and enter the test chamber to ensure that the air is free of impurities. The primary pressure without oil pollution is .MPa. The bottom of the box is equipped with an exhaust hole to prevent the pressure difference between the inside and outside of the box to ensure the normal conduct of the test.
The box is heated by electric heating for the inner tank, saving water and electricity resources. It heats up quickly and distributes temperature and humidity evenly. The sample rack is designed in accordance with national standards to have upper and lower layers tilted by degrees and degrees, and can also be hooked.
The equipment control system is designed on the right side of the box and is easy to operate. The control box panel is covered with a transparent plate to protect it from dust and water.
