Technical Characteristics and Application Research of LISUN Salt Spray Corrosion Test Chamber

1. Introduction

In complex environments such as marine climates and industrial salt–alkali conditions, salt spray corrosion is one of the main causes of failure for metal materials, coated products, electronic components and other products. Chloride ions penetrate the material protection layer and undergo electrochemical reactions with the substrate, resulting in rust, short circuits, structural damage and other problems, which seriously affect the service life and safety of products. As a special equipment for accelerated simulation of salt spray corrosion environments, the salt spray corrosion test chamber can quickly evaluate the salt spray corrosion resistance of products through artificially simulated corrosion conditions, becoming a key tool for product development, material selection and quality verification.

To meet the corrosion resistance testing requirements of various industries, LISUN has developed the YWX/Q series salt spray corrosion test chambers. Among them, the YWX/Q-010 model is widely used in electronics, hardware processing, coating surface treatment and other fields due to its precise environmental control capability, diversified test modes and well–adapted structural design. By simulating a real salt spray corrosion environment, this equipment can quickly identify defects in material protection layers and loopholes in product structure design, providing scientific test data support for enterprises to improve product quality and of great significance for enhancing the environmental adaptability of industrial products.

2. Core Technical Characteristics of LISUN YWX/Q-010 Salt Spray Corrosion Test Chamber

2.1 Overall Structural Design

The YWX/Q-010 salt spray corrosion test chamber adopts an integrally formed box made of imported corrosion–resistant PP plate. The seamless welding structure fundamentally solves the problem of box leakage and ensures the tightness and stability of the salt spray test environment. The equipment is equipped with stainless steel gas springs for opening the cover, which not only improves operation convenience but also avoids fluctuations in ambient temperature and salt spray concentration caused by cover opening during the test compared with the traditional manual cover opening. At the same time, the equipment is equipped with independent brine tank and test chamber. The brine tank has a volume of 32L, which can meet the brine supply demand for long–term continuous tests and reduce the frequency of manual fluid replacement.

2.2 Precise Temperature, Humidity and Salt Spray Control

Temperature control is the core part of salt spray corrosion testing. The test chamber temperature range of the YWX/Q-010 salt spray corrosion test chamber is room temperature to +55℃, and the saturation bucket temperature range is room temperature to +70℃. The saturation bucket effectively reduces nozzle crystallization by heating and filtering compressed air, ensuring the uniformity of salt spray. The temperature uniformity of the equipment is ≤2℃, and the temperature fluctuation is ≤±0.5℃, which can maintain stable test environment temperature and meet the temperature accuracy requirements of national and international salt spray test standards.

In terms of salt spray control, the salt spray settlement rate of the equipment can be stably maintained at 1–2ml/80cm²/h (16–hour average). It supports three spraying modes: continuous, intermittent and programmable, which can adjust the spraying mode according to different test standards and testing requirements to accurately simulate salt spray corrosion conditions of different intensities in the natural environment. At the same time, the equipment is equipped with an automatic monitoring function for salt spray settlement, recording salt spray settlement data in real time to ensure the accuracy and traceability of test data.

2.3 Diversified Test Modes

The YWX/Q-010 salt spray corrosion test chamber can stably realize three mainstream test modes: Neutral Salt Spray (NSS), Acetic Acid Salt Spray (AASS) and Copper Accelerated Acetic Acid Salt Spray (CASS), covering the most commonly used salt spray test types in the industrial field. The neutral salt spray test is suitable for corrosion resistance testing of conventional materials and products; the acetic acid salt spray test is for product corrosion evaluation in acidic environments; the copper accelerated acetic acid salt spray test accelerates the corrosion process by adding copper ions, suitable for rapid testing of high–protection products. The three test modes can meet the diversified testing needs of different industries and products.

2.4 Intelligent and Safety Protection Design

The equipment has a test time timing control function of 0–9999 hours, which can freely set the test duration according to test requirements and realize unattended continuous testing. At the same time, it is equipped with three sound and light alarm devices for water shortage, over–temperature and low air pressure. The over–temperature protection adopts a dual mechanical and electronic protection design. When the equipment has insufficient brine, abnormal temperature, low air pressure and other conditions, it can send an alarm signal in time and stop the test, effectively avoiding equipment damage and test data failure. The sample rack adopts a V–shaped groove and O–shaped round rod combination design, which can form a test angle of 20°±5°, meeting the sample placement requirements of salt spray tests. Customized special sample racks are also available to adapt to test samples of different sizes and shapes.
