Description

Technical Field

[0001] The invention relates to the technical field of coating detection, and in particular to a detection method for antibacterial hand-feel coating. Background Art

[0002] Antimicrobial coatings are special coatings that can inhibit or kill microorganisms such as bacteria, fungi, and molds, and are widely used in the fields of medical treatment, food processing, and home furnishing. As people's living standards improve, the demand for antimicrobial coatings is also growing. Therefore, the detection method of antimicrobial coatings is crucial to ensure their performance and effectiveness.

[0003] Antibacterial paint is a liquid. The main method for testing antibacterial paint on the market is to quantitatively inoculate bacteria on the paint sample, detect the number of live bacteria in the sample after a certain period of cultivation, and calculate the antibacterial rate of the sample. This method has a long observation period and a complicated process, and it is impossible to test the fluidity of antibacterial paint.

[0004] Since antibacterial coatings are liquids, the adhesion ability of antibacterial coatings is also very important. However, current antibacterial detection methods ignore the test of adhesion ability, and therefore cannot conduct comprehensive detection of antibacterial coatings.

[0103] The present invention has the following beneficial effects:

[0104] 1. This is a testing method for antibacterial feel coatings. By setting different experimental temperature sets, the performance of sample coatings at various temperatures is gradually tested to ensure that the coatings can maintain stable performance in a variety of use environments. This not only improves the comprehensiveness of the test, but also effectively identifies the applicability of the coating.

[0105] 2. This method for testing antibacterial feel coatings randomly selects coatings from a sample set and uses a square glass plate for coating testing, which reduces the impact of human error and bias through randomization. This method increases the fairness and reliability of the test and makes the results more scientific.

[0106] 3. A detection method for antibacterial feel coating, which coats qualified sample coatings, performs performance tests on the formed coating area, determines the coating direction, draws multiple straight lines perpendicular to the coating direction on the coating area, obtains line segments of the straight lines in the coating area, and enters them into a set, calculates the difference between adjacent elements in the set, records the sum of all differences as the total difference, uses the ratio between the total difference and the number of differences as the standard average difference, calculates the average difference of sample plates that need to be performance tested, and compares the average difference with the standard average difference to determine whether the performance test of the current style plate is qualified. By coating the sample coating on the smear plate and performing standardized performance tests, including obtaining edge contours and calculating growth values, the accuracy and comparability of the test results are ensured. By comparing the performance test data of the test sample plate with the standard sample plate, it can intuitively reflect whether the coating performance test is qualified, thereby improving production efficiency and production quality.

[0107] 4. This method for detecting antibacterial feel coatings strictly controls the volume of the sample coating and ensures the consistency of the coating area through the operation of rectangular grooves. This method allows the coating area to be evenly distributed, reduces the result error caused by uneven coating, and ensures the accuracy of the test results.

[0108] 5. This is a method for testing antibacterial feel coatings. When the qualified sample coating is applied, the line segments in the sub-coating area are analyzed and processed to calculate the standard average growth value. This ensures that different sample plates can be compared during the test and generates unified standard data, which improves the comparability of the data.

[0109] 6. This detection method for antibacterial hand-feel coating ensures the accuracy of performance detection by judging and processing the standard set and the test set, especially calculating and sorting the differences between elements, and avoids the overall judgment being affected by abnormal fluctuations in individual data.

[0110] 7. This is a detection method for antimicrobial feel coatings. The adhesion test ensures that the coating of the style board has sufficient adhesion by setting the adhesion distance threshold and the minimum adhesion judgment element. The qualified standard of the adhesion test enables the coating to effectively resist peeling and other problems in actual applications, improving the practicality and durability of the coating.

[0213] Respectively obtain the contours of adjacent elements in the attachment judgment set;

[0214] Enter the shortest distance between adjacent element contours into the attachment distance set;

[0215] Set the attachment distance threshold m;

[0216] The adhesion distance threshold m is a constant, which is used to define the shortest distance between adjacent sub-coating areas. Whether the adhesion test is qualified is determined based on the difference between the shortest distance and m.

[0217] Get the minimum value in the attachment distance set and record it as the attachment judgment element;

[0218] If the attachment judgment element is less than m, the current style board attachment test is marked as unqualified;

[0220] The adhesion test ensures that the paint on the style board has sufficient adhesion by setting the adhesion distance threshold and the minimum adhesion judgment element. The qualified standard of the adhesion test enables the paint to effectively resist peeling and other problems in actual applications, improving the practicality and durability of the paint.

[0221] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0222] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
