The uniformity of salt spray settling in the salt spray test chamber is a key factor in ensuring the reliability of the test results.Q-FOGThe test chamber ensures the uniformity of settlement through system hardware design and rigorous maintenance measures. The specific measures are as follows:

1、 System hardware design guarantee

1. Optimization of box material: High performance fiberglass is used as the box material, and the inner cavity of the box is integrally formed. This material is not only highly corrosion-resistant, but also has a smooth surface, which can effectively reduce the adhesion and residue of salt spray on the inner wall of the box, and reduce the impact of secondary deposition on the uniformity of settlement.

2. Precision spray system: The part of the nozzle that comes into direct contact with the salt solution adopts a fully plastic structure to avoid interference from metal parts on the salt solution; At the same time, the nozzle is designed with a spherical installation, making it convenient for operators to fix and adjust the angle. The system is equipped with a flow meter that can accurately distribute the flow rate of each nozzle, ensuring a uniform distribution of the total amount of salt spray. When the spray volume exceeds the set value±10%At that time, the equipment will automatically issue an alarm prompt (the test will not stop), reminding the operator to check the equipment status in a timely manner.

3. Airflow guidance regulation: Vertical deflectors or horizontal baffles are installed inside the box to guide the salt spray to flow along a predetermined path, effectively reducing turbulence and eddies, and avoiding local settlement differences caused by airflow turbulence. By optimizing the power of the fan and the structure of the air duct, the overall airflow velocity inside the box is precisely controlled to prevent local airflow from flowing too fast or too slowly and disrupting the uniform distribution of salt spray.

4. Sealed protection design: adopting a triple safety sealing design of snap spring, front double lock buckle of the box cover, and dry sealing strip. This design can minimize external air interference, stabilize the air pressure environment inside the box, and prevent salt spray from escaping or external airflow from infiltrating, providing a stable internal environment for even settling of salt spray.

5. Regular testing and calibration: Equipped with calibration corrosion plates, it can monitor the salt spray deposition in specific areas in real time to monitor the equipment's operating status and ensure the stability of the deposition uniformity during long-term operation.

2、 Equipment maintenance and operation standard guarantee

To maintain the uniformity guarantee capability of the equipment, the following maintenance and operation specifications must be strictly followed:

-Clean the nozzle: clean the nozzle regularly to prevent uneven spray volume caused by nozzle blockage, which will affect the settling effect of salt spray;

-Maintain the bubble tower: Regularly inspect and maintain the bubble tower to prevent impurities from entering the spray system, ensuring the purity of the salt solution and spray stability;

-Check the sealing ring: Regularly check the status of the sealing strip, replace the aging sealing ring in a timely manner, and prevent salt spray leakage or external humid air intrusion caused by sealing failure;

-Standardized parameter settings: Strictly follow the manufacturer's recommended standards to set test parameters (such as pump speed, air pressure, etc.) to avoid human error affecting the uniformity of salt spray.

3、 Practical application suggestions

In practical applications, it is recommended to choose the appropriate one based on specific testing requirements (such as sample type, reference standards, etc.)Q-FOGEquipment model and regularly verify the operating status of the equipment to ensure the reliability of test data.
