• Composite Salt Spray Test Chamber: Core Performance Analysis

  Dec 12, 2025

      In the corrosion resistance testing of metal materials, coatings and components, the composite salt spray test chamber is an indispensable core equipment. It breaks through the limitations of traditional single salt spray tests, can simulate complex natural environments, and provides accurate data for product reliability evaluation. The following analyzes its key performance from four core dimensions. I. Accurate Environmental Parameter Control Capability Composite salt spray tests have extremely high precision requirements for parameters such as temperature, humidity and salt spray concentration, and the control performance of the equipment directly determines the validity of test data. Temperature and Humidity Control: Supports wide-range adjustment of temperature (5℃-50℃) and humidity (45%-98%RH) in the salt spray chamber. The temperature fluctuation is ≤±0.5℃ and the humidity deviation is ≤±3%RH, which can stably simulate typical corrosive environments such as high humidity in coastal areas and high temperature with high salt. Salt Spray Concentration Regulation: The salt water injection volume is controlled by a high-precision metering pump, and the salt spray sedimentation volume is stably maintained at 1-2ml/(80cm²·h). It supports the preparation of sodium chloride solution with a concentration of 5%-20%, and is also compatible with special test requirements such as acetic acid and copper-accelerated acetic acid salt spray (CASS). II. Multi-dimensional Environmental Simulation Capability Different from traditional salt spray machines, the core advantage of composite models lies in the simulation of "composite" scenarios, which can reproduce the synergistic corrosion effect of "salt spray + humidity + temperature cycle" in natural environments. Multi-mode Switching: Supports seamless switching between three modes: continuous salt spray, intermittent salt spray and damp-heat cycle. For example, it simulates the alternating environment of high-temperature salt spray during the day and low-temperature high-humidity at night, which is closer to the actual service scenario of products. Full-range Corrosion Coverage: The diameter of salt spray particles is controlled at 1-5μm. Through the annular layout of multiple nozzles, the uniform distribution of salt spray in the chamber is realized, covering the test samples without dead ends, ensuring the comparability of corrosion degrees of samples at different positions. III. Stable and Reliable Operation Performance Corrosion resistance tests often last for several days to months, and the long-term operation stability of the equipment is the key to ensuring the smooth completion of the test. Anti-corrosion Structure Design: The inner tank of the test chamber is made of 316L stainless steel, and the nozzles are made of salt-corrosion-resistant ceramic materials, which can effectively resist the corrosion of the equipment itself by salt spray and extend its service life. Intelligent Protection Mechanism: Equipped with functions such as low salt water level alarm, over-temperature protection and compressor overload protection. It will automatically shut down and give a prompt when parameters are abnormal, avoiding test interruption or sample damage. IV. Convenient Operation and Data Management Humanized operation design and complete data recording functions improve test efficiency and ensure data traceability. Intelligent Control: Adopts a 7-inch touch screen, supports test parameter presets and automatic process operation, and can store more than 100 sets of test schemes, facilitating the call of repeated tests for similar products. Data Visualization: Displays real-time data such as temperature, humidity and salt spray sedimentation in the chamber, supports regular data printing and USB export, and meets the standardization requirements of test reports. Conclusion     The composite salt spray test chamber’s core performance lies in the integration of "precision control, multi-dimensional simulation and stable operation". For corrosion resistance testing of auto parts, marine engineering equipment or electronic components, a reliable chamber provides strong data support for product quality enhancement.
