Collection cup of salt spray test machine
The measuring cup used in Dongguan Zhongzhi Times Testing Equipment Co., Ltd.’s salt spray testers is a crucial accessory, offering the following features and functions:
- Structure and Material:
- Structure: Typically cylindrical and regularly shaped, it facilitates accurate measurement and observation. Its design is generally simple, fulfilling the basic function of collecting salt spray precipitation. Some measuring cups may feature graduated markings for easier reading of the collected volume.
- Material: Glass or corrosion-resistant plastic are commonly used. Glass offers excellent transparency and chemical stability, enabling accurate observation of the collected liquid and resisting chemical reactions with salt spray. Corrosion-resistant plastic is lightweight, unbreakable, and well-resistant to salt spray corrosion, making it easy to process and use.
- Function and Use:
- Collecting Salt Spray Settling: During operation, the salt spray tester generates salt spray, which settles to various locations within the test chamber over a period of time. The main function of the collection cup is to collect the salt spray sediment so that testers can accurately measure the amount of salt spray sediment. This is a key indicator for evaluating the performance of the salt spray tester and the corrosion resistance of the test specimens.
- Monitoring Spray Results: By observing the amount of salt spray liquid collected in the collection cup, you can determine whether the salt spray tester’s spray is uniform and stable. If the amount of salt spray liquid in the collection cup is too little or too much, it may indicate a problem with the salt spray tester’s spray system, such as a clogged nozzle or unstable spray pressure, which requires timely adjustment and maintenance.
- Usage Precautions:
- Installation Location: The collection cup must be installed in a suitable location inside the salt spray tester to ensure accurate collection of the salt spray sediment. Generally, the collection cup is installed in a specific area within the test chamber to avoid interference from the test specimen or other components.
- Regular Cleaning: Because salt spray is corrosive, the collection cup must be cleaned promptly after use to prevent residual salt spray from corroding the cup, affecting its service life and measurement accuracy. Rinse with distilled or deionized water for cleaning, then dry.
- Accurately read the data: When reading the amount of salt spray liquid in the collection cup, keep your eye level with the scale line to ensure accurate readings. Also, be sure to record the collection time to calculate the amount of salt spray deposition per unit time.
