1. Product Name and Purpose

2. Product Features

• Robust and Corrosion-Resistant Structure
  • The test machine is constructed with a high-strength, corrosion-resistant alloy frame and enclosure. The materials are carefully selected to withstand the corrosive effects of the salt spray and maintain structural integrity over long periods of testing. The interior of the chamber is designed for easy access and cleaning. The door is equipped with a secure locking mechanism and a pressure-resistant viewing window, allowing operators to closely monitor the test process without compromising the integrity of the chamber. The seals and gaskets used are of the highest quality to ensure a hermetic seal, preventing any leakage of the salt spray.
• Precision Salt Spray Generation System
  • The heart of the machine is its state-of-the-art salt spray generation system. It can accurately control the concentration of the salt solution, typically ranging from 3% to 5% by weight. The system utilizes advanced pumps and precision nozzles to produce a fine and uniform salt spray. The nozzles are strategically placed and calibrated to ensure even distribution of the salt particles throughout the chamber, mimicking the natural deposition of salt in a corrosive aerospace environment. The flow rate of the salt spray can be precisely adjusted, allowing for the simulation of different levels of salt exposure, from mild coastal conditions to more extreme marine or industrial settings.
• Accurate Temperature and Humidity Control
  • The machine offers highly accurate control over temperature and humidity. The temperature can be set within a range of 15°C to 45°C, with an accuracy of ±0.2°C. The humidity control range extends from 80% to 95% relative humidity, with an accuracy of ±1.5% RH. Temperature and humidity play crucial roles in the corrosion process, and the precise control of these parameters ensures that the test conditions closely replicate real-world scenarios. For example, in a high-altitude flight over a humid coastal area, the combination of temperature, humidity, and salt spray can have a significant impact on the corrosion of aircraft components, and this machine can accurately simulate such conditions.
• Intuitive Control Panel and Data Acquisition Interface
  • The equipment is equipped with an intuitive control panel that simplifies the operation and parameter setting. Operators can easily adjust the salt spray concentration, temperature, humidity, and test duration using the user-friendly interface. The control panel also provides real-time displays of the current test conditions, as well as any alarms or warnings. The machine is integrated with a comprehensive data acquisition system. It records all relevant test data, such as temperature and humidity histories, salt spray concentration profiles, and any observable signs of corrosion in the test samples. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system can also generate detailed test reports in various formats, facilitating easy documentation and sharing of results.
• Versatile Sample Fixturing and Placement
  • The interior of the chamber is designed to accommodate a wide variety of aerospace sample sizes and shapes. It can be equipped with adjustable racks, trays, and custom-made holders to ensure proper positioning and exposure of the test samples. The sample fixturing is made of materials that are highly resistant to corrosion and do not contaminate the test environment. This flexibility allows for the testing of different products, from small avionics components and connectors to large aircraft structural parts and engine assemblies. For example, an aircraft wing panel can be mounted on a specialized fixture to evaluate the corrosion resistance of its surface coatings and joints, while a set of avionics circuit boards can be placed on a rack to test their resistance to salt-induced electrical malfunctions.

3. Specific Parameters

• Maximum Salt Spray Concentration and Accuracy
  • The machine can achieve a maximum salt spray concentration of 5% by weight, with an accuracy of ±0.05%. This extremely high level of precision in controlling the salt concentration is essential for conducting accurate and repeatable tests. Aerospace components often have very strict requirements for corrosion resistance, and the ability to precisely adjust the concentration allows manufacturers to evaluate their performance under specific and demanding conditions. For instance, a critical engine component may need to be tested at a precisely calibrated salt concentration to determine its long-term durability.
• Temperature and Humidity Range and Accuracy
  • The temperature range of 15°C to 45°C, with an accuracy of ±0.2°C, and the humidity range of 80% to 95% RH, with an accuracy of ±1.5% RH, provide a comprehensive assessment of the effect of environmental conditions on aerospace corrosion. These ranges cover a wide variety of potential real-world situations, from mild coastal flights to more extreme conditions. The accurate control of temperature and humidity helps in understanding how different components behave in different climates and operational scenarios.
• Spray Pattern and Coverage
  • The salt spray nozzle produces a fine mist with a droplet size ranging from 2 microns to 10 microns. The spray pattern is engineered to ensure uniform coverage of the test samples, with a coverage area of up to 99% within the chamber. This ensures that all parts of the sample are exposed to an equal amount of salt spray, providing highly reliable test results. The uniformity of the spray is crucial, especially when testing complex and high-value aerospace parts like aircraft frames, where any area of inconsistent exposure could lead to inaccurate corrosion assessment and potential safety risks.
• Testing Volume and Payload Capacity
  • The machine offers a customizable testing volume, with options ranging from 1 m³ to 10 m³. The payload capacity can be adjusted according to the size and weight of the test samples, with a maximum capacity of up to 2000 kg. This allows for the testing of a significant number of samples or larger and heavier aerospace assemblies. For example, a batch of small avionics connectors can be tested simultaneously in a smaller chamber, while a complete aircraft engine or a section of an aircraft fuselage can be accommodated in a larger one.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a frequency of up to 150 Hz, providing a detailed record of the salt spray concentration, temperature, humidity, and any changes in the test samples. The resolution of the salt spray concentration data is 0.005%, the temperature data is 0.05°C, and the humidity data is 0.05% RH. This high-resolution data is invaluable for identifying even the slightest trends and potential failure points, allowing for a more accurate assessment of product corrosion resistance.
