Salt spray test chamber water source requirements
Zhongzhi Times Salt spray equipment has various water sources, and different locations have different water requirements:
- Water for Salt Spray Solution:
- Recommended Water: Use purified or distilled water. Tap water contains many impurities and minerals, which may affect the purity and performance of the salt spray solution, leading to inaccurate test results. Salt spray solutions prepared with purified or distilled water can maintain a moderate pH value. The pH of the solution in the collector is generally required to be between 6.5 and 7.2.
- Water for Saturated Tanks:
- Recommended Water: Use distilled or purified water first. This reduces impurities in the water and minimizes the impact on the equipment. While tap water can also be used, the frequency of equipment cleaning and water changes will need to be increased to prevent impurity accumulation.
- Water for Chamber Lid Sealing:
- Acceptable Water: Tap water is generally sufficient. Because the main function of the chamber lid sealing water is to seal the chamber, the water purity requirement is not high; it only needs to meet the sealing requirements of the test and prevent the salt spray gas from escaping. However, if conditions permit, distilled water is preferred.
- Laboratory Water (Water Used Within the Chamber):
- Recommended Water: Purified or distilled water is generally recommended. This is to prevent impurities in the water from adversely affecting the chamber during heating, potentially causing cracking and aging. The recommended water volume is typically around 100-200L.
Also, the water pressure at the source should be maintained within the 1-3 kg range to ensure proper water replenishment. When connecting the water inlet and outlet of the equipment, use a hose and secure with a sealing ring to prevent leakage.
