In the fields of electrical and electronic engineering, automotive parts, communication equipment, etc., the corrosion resistance of products directly affects their service life and reliability. The corrosion-resistant salt spray test chamber can accelerate the evaluation of the corrosion resistance of metal materials, coatings, and electronic components by simulating salt spray corrosion conditions in marine or high humidity industrial environments. It has become an important testing tool for product quality control and research and development stages.

1、 Core features: Accurate simulation and efficient testing

Multi specification test space adapted to different needs

Test box providedSH-60toSH-160Four models, laboratory capacity coverage110Lto800LIt can accommodate test samples ranging from miniature connectors to large automotive components. For example,SH-120Model number（120×100×50cm）Hundreds of standard sized electrical switches can be placed simultaneously for batch testing, significantly improving testing efficiency.

Dual mode salt spray control technology

The device supports neutral salt spray（NSS）Compared to acidic salt spray（CASS）Two experimental modes:NSSSimulate the ocean atmospheric environment with a constant laboratory temperature35℃±1℃Salt waterPHvalue6.5-7.2；CASSThe mode is achieved through50℃High temperature and copper salt accelerate corrosion, suitable for testing military products with strict requirements for anti-corrosion performance. Two modes can be switched with one click to meet different standard requirements.

Intelligent spray and temperature and humidity control system

Using precision glass nozzles and conical dispersers to ensure even coverage of salt spray particles on the sample surface and avoid local concentration differences. The laboratory uses steam for direct heating, which increases the heating speed compared to traditional resistance heating30%Temperature fluctuation≤±0.1℃The saturated air tank adopts Henry's law humidification technology, and the humidity control accuracy reaches±2%RHRealistic restoration of high humidity corrosive environment.

2、 Structural advantage: equal emphasis on durability and safety

Construction of corrosion-resistant materials

The main body of the laboratory adopts5mmthickPVCPolyvinyl chloride board and acrylic impact resistant board are used for sealing doors, which can withstand salt water erosion for a long time without deformation. Selection of saturated air tankSUS#304Made of stainless steel material, with a pressure bearing capacity of up to0.3MPaEnsure no leakage risk in high temperature and high humidity environments.

Multiple security protection mechanisms

The equipment is equipped with a dual over temperature protection system. When the laboratory temperature exceeds the set value2℃Automatic power outage during operation; The saltwater level sensor can monitor the status of the storage tank in real time, triggering an alarm and suspending the test when the liquid level is low. The design of a hidden reagent replenishment bucket reduces the risk of manual operation and is easy to clean and maintain.

3、 Industry application value: Shorten R&D cycle, reduce quality risks

Taking the electrical industry as an example, a certain enterpriseSH-160Type test box for outdoor distribution boxes480hourCASSTesting has found that traditional coatings are200Bubbling phenomenon appeared after hours. After optimizing the coating formula based on this, the actual service life of the product is reduced5Year extended to12In the year, the customer complaint rate has decreased76%In the field of communication, the test box helped a base station antenna manufacturer screen out joint suppliers with insufficient salt spray resistance, avoiding a surge in maintenance costs after mass deployment.

This test chamber strictly followsGB/T 2423.17TheASTM B117According to international standards, its test data has been included in the supplier access system by companies such as General Motors and Siemens, becoming a quality standard for global competition in the electrical and electronic industry“pass”.
