As an important equipment in the field of environmental simulation testing, the anhydrous heating salt spray box provides a more reliable solution for material corrosion resistance testing through innovative anhydrous heating technology and high-precision control system. The structural design and product advantages are mainly reflected in the following aspects:

1、 Modular box structure: equal emphasis on function integration and safety protection

Three layer composite insulation box
The outer layer adoptsPVCImpact resistant board, filled with polyurethane insulation layer in the middle layer, and reinforced with titanium alloy board or glass fiber composite material in the inner layer. This structure ensures the strength of the box (can withstand)8-10Continuous corrosion over the years, coupled with a double-layer hollow design to reduce energy consumption30%Specially designed annular water sealing system and dry sealing technology to prevent salt spray overflow and prevent corrosion of laboratory equipment.

Intelligent temperature control system
The bottom and side walls are integrated with aluminum plate heating modules, which work togetherEGOTemperature regulator implementation±0.1℃Temperature control accuracy. Built in dual over temperature protection device, when the temperature inside the box is abnormal,0.5Cut off the heating power within seconds and trigger an audible and visual alarm. The power-off memory function can automatically save the test progress and seamlessly connect unfinished tests after power supply is restored.

Pneumatic assisted unboxing system
Large models are equipped with pneumatic cylinder automatic opening and closing devices0.95The low front design allows operators to complete sample retrieval and placement with one hand. box cover120°The top corner opening structure, combined with a transparent observation window, facilitates real-time observation while avoiding direct contact with salt spray.

2、 Core product advantages: precise control and efficient operation and maintenance

Anhydrous radiation heating technology
Breaking through the traditional water tank heating mode, using titanium alloy electric heating plates for direct radiation heat transfer. This technology achieves temperature uniformity±1℃Increase the heating rate40%And eliminate the fluctuation of salt water density caused by water mist condensation, improving the reproducibility of experimental data25%.

Intelligent spray control system
Bernoult principle salt absorption device cooperates with Taiwan, China's special glass nozzle to achieve1-2ml/80cm²/hAdjustable settlement amount. The peristaltic pump replaces the compressed air siphon system to make the spray uniformity error≤0.2ml/hThe filtering system can intercept0.5μmThe above particles extend the service life of the nozzle to3000More than hours.

Full process automation management
FUJI 5.7Integrated inch touch screenPLCControl system, supporting99Pre set experimental procedures for the group. Automatic dry compressed air switching function, can be executed synchronouslyNSSTheACSSTheCASSWaiting for multiple standard tests. The intelligent water replenishment system is linked with a liquid level sensor and an electromagnetic valve to prevent water shortage0.3Start replenishing water within seconds, and the test will automatically resume once the water level is restored.

Maintain convenience design
The plug-in modular structure reduces the replacement time of components such as heaters and nozzles to10Within minutes. Hidden reagent replenishment bottle equipped with water level visualization window, improving cleaning and maintenance efficiency60%Randomly included standard conversion fittings, compatible with mainstream laboratory interface standards worldwide.

3、 Extension of application value

This device has passed throughASTM G85TheGB/T 10125wait20The remaining international certifications can extend the testing cycle from natural exposure in anti-corrosion testing of automotive components5Year shortened to480Hour. its0.4L/hLow salt water consumption design, combined with80LLarge capacity solution tank, supporting continuous operation7Continuous testing is particularly suitable for long-term certification requirements of aerospace materials.

The anhydrous heating salt spray box, through structural innovation and technological upgrading, not only improves testing accuracy and equipment stability, but also reduces comprehensive usage costs with an intelligent operation and maintenance system, becoming a key equipment in the field of material environmental adaptability research.
