Product Description
This alternating salt spray corrosion test equipment uses salt solution Or acidic salt-containing solutions can be achieved by using this test chamber without moving the test sample in a test chamber: four cycles (alternating) of salt spray, drying, standard atmospheric pressure, constant temperature and humidity, and low-temperature storage. The test effects are based on the material under the test requirements. Or the product undergoes accelerated corrosion testing to measure the degree of damage suffered by the material or product within a certain time range. This equipment is used to assess the resistance to salt spray corrosion, drying, standard atmospheric pressure, constant temperature and humidity, and room temperature storage capabilities of materials and their protective layers, as well as to compare the process quality of similar protective layers. It is an artificial simulation of salt spray corrosion, drying, and standard Tests in atmospheric pressure, constant temperature, humidity and low-temperature storage environments can also be used to evaluate the ability of certain products to resist salt spray corrosion.
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 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.
Our country has produced relevant national standards for this salt spray test and made detailed regulations. It has developed from the initial simple neutral salt spray test to: acetate salt spray test, copper salt accelerated acetate salt spray test Test and alternating salt spray test and other forms. This test chamber is a cyclic test equipment that uses a touch screen to simulate these environmental factors in a box in a fully automatic manner. It also complies with domestic standards and relevant international standards.
This equipment is widely used in enterprises and institutions such as automobiles and motorcycles, military equipment, electrical and electronics, chemical industry and metallurgy, quality inspection and measurement, postal and telecommunications, ships and railways, as well as universities, colleges and scientific research institutions.

The lid of the box is made of high-quality transparent plates, which have a smooth and bright appearance, are corrosion-resistant, easy to clean, and have no leakage. They have good temperature resistance and high strength. Various auxiliary accessories and facilities are also made of temperature-resistant and corrosion-resistant materials and will not cause electrochemical corrosion reaction with the test piece.
.The box cover is designed to open at an optimal top angle so that the condition of the specimen in the room can be clearly observed. The beveled angle of the box cover prevents condensation water generated during the test from dripping onto the sample and affecting the test results.
.The box cover and box body are water-sealed to prevent salt spray from overflowing, which may affect the test results, corrode other equipment in the room, and even cause harm to test operators.
. The spray system uses Hunter's law to spray. It is a tower spray device with a nozzle diameter of ￠. The nozzle is made of pure quartz glass and is durable. The salt spray is distributed uniformly and the sedimentation amount can be adjusted freely without crystallization.

. The sample rack is designed in accordance with national standards to have upper and lower layers tilted by degrees and degrees. Hooks can also be used to facilitate testing of the tested items from all angles.
. The air duct temperature cycle uses a corrosion-resistant long-axis fan motor and a corrosion-resistant multi-wing centrifugal wind wheel to achieve strong convection and vertical diffusion circulation to make the temperature and humidity in the laboratory uniform and stable
. The evaporator for refrigeration of the test chamber also serves as a dehumidifier, which can meet the humidity requirements at different temperatures and undergo anti-corrosion treatment
. This test equipment is equipped with a rapid mist exhaust device. Opening the mist exhaust device at the end of the test can reduce the harm caused by the floating salt spray to the human body and other metal equipment
