Walk-in Composite Salt Spray Test Chamber 15m³

Overview:

1. The corrosion of protected and unprotected metal materials is affected by many environmental factors, which mainly depends on the type of metal material and the type of environment. It is impossible to design a laboratory accelerated corrosion test room that includes all environmental factors that affect corrosion resistance. Therefore, the laboratory test is designed to simulate the factors that play a major role in the corrosion of metal materials. This equipment is designed to simulate and increase the impact of the environment on metal materials exposed to outdoor atmospheres with salt pollution and accelerated corrosion. The equipment includes test methods for cyclically exposing specimens to salt spray, dry, and humid heat environments. This equipment test is a comparative test, and the test results cannot predict the long-term results of the corrosion resistance of the same metal material used under these environmental conditions. However, this method can still provide valuable information on the relevant performance of materials exposed to salt pollution environments similar to the test conditions. Compared with traditional accelerated corrosion tests such as neutral salt spray test (NSS), acetic acid salt spray test (AASS), and copper accelerated acetic acid salt spray test (CASS), the biggest advantage of this equipment test is that it can better reproduce the corrosion occurring in outdoor salt pollution environments.

2. The accelerated corrosion test of this equipment is applicable to: metals and their alloys, metal coatings (anodic and cathodic), conversion coatings, anodized coatings, organic coatings on metal materials, etc.

Key Features:

The composite salt spray composite test room has the entire inner box space with corrosion resistance. The inner box is made of corrosion-resistant materials and has excellent thermal insulation performance. In addition, the equipment also has the following functions:

(1) It has an emergency braking function. A brake switch is installed on the equipment. When an abnormal situation occurs, the equipment can be powered off by controlling the switch.

(2) The equipment is equipped with corresponding system software. The software can run stably on the provided operating system. The software interface is in Chinese or English and has no service life limit. The software includes temperature change test, humidity, accuracy calibration part, and equipment self-test module part.

(3) The system software can record, automatically save, and optimize data in real time. The temperature-time, humidity-time and other curves can be drawn through software settings.

(4) The system software is equipped with a security protection parameter interface, and after the setting is completed, it will be given priority during the test process to ensure the safety of the test.

(5) The system software can achieve the function of test data security protection. The software has an administrator function that can limit the operating permissions of general operators.

(6) The system software has the function of post-data processing, and can support the import of multiple data files, data screening, and arbitrary X-axis and Y-axis selection.

(7) The equipment has multiple functions such as high temperature, wet heat, drying, and salt spray, and can realize automatic cycle control or single function control, simple operation, and data management.
