Description

Technical field:

[0001] The present invention relates to two disciplines of biological science and material science, belongs to interdisciplinary field, and its specific content is to use thiobarbituric acid method (abbreviated TBA method) to measure the oxidized unsaturated fatty acid of bacterial cell membrane after the action of antibacterial stainless steel material Degree, and then calculate the method of antibacterial performance of different antibacterial stainless steel materials. Background technique:

[0002] Antibacterial stainless steel is a new type of functional antibacterial material known as having cross-age significance. It has good mechanical and antibacterial properties and has a wide range of applications, especially in areas that emphasize antibacterial, such as food industry, medical equipment, kitchen and bathroom, etc., can be Play an effective and long-lasting role. The development and application of antibacterial stainless steel materials can not o...
