Description

Technical Field

[0001] The utility model relates to the field related to water protection material detection, in particular to an immersion device used for protection material detection. Background Art

[0002] In the field of drinking water safety, according to the relevant provisions of my country's "Regulations on Inspection of Drinking Water Hygiene and Safety Products of the Ministry of Health" (2001 Edition) and GB / T 17219-1998 "Safety Evaluation Standards for Drinking Water Distribution Equipment and Protective Materials", the protective materials used in drinking water distribution facilities, such as epoxy resin coatings, polyester coatings (containing alkyd resin components), acrylic resin coatings and polyurethane coatings, must meet strict health and safety performance standards. In order to verify the health and safety of such protective materials, the method commonly used in the industry is to immerse the samples under certain conditions and evaluate the compliance of the products by measuring the concentration of harmful substances dissolved in the immersion liquid.

[0003] In the current testing methods, the pre-treatment steps of protective material samples mostly rely on manual operation. First, the samples are fully washed with pure water, then transferred to a special container, soaking water is added and soaking test is carried out within a specified time period (such as 1 day, 3 days, 5 days, 10 days, 20 days, 30 days). However, there are many problems in this process: first, the placement of samples during the soaking process is not standardized enough. For example, the paint pieces may not be suspended vertically or fixed as required, resulting in contact between samples or uneven wetting, affecting the accuracy of the test results; secondly, due to the long soaking cycle, manual operation is difficult to achieve long-term continuous and accurate temperature control, especially under the constant temperature of 25±5℃; thirdly, the pH value control of the soaking solution is also a challenge. The lack of an effective real-time monitoring mechanism makes it difficult to maintain the pH value within the standard range (such as 8.0±0.2).

[0004] In summary, the existing immersion detection technology involving drinking water sanitation and safety protection materials has significant operational difficulties and technical bottlenecks in sample placement, temperature control and pH maintenance, and it is urgent to develop a more accurate and more automated immersion device to solve the above technical problems, improve the consistency and reliability of detection, and ensure that the sanitation and safety performance of drinking water distribution equipment and protective materials is scientifically and fairly evaluated.
