Abstract

The invention relates to a preparation method of a bacteriostat stainless steel cup, and belongs to the technical field of preparation of stainless steel products. The preparation method comprises the following steps: making 1Cr18Ni9 stainless steel into the shape of a cup, and immersing the cup in a FeCl3.6H2O solution of which the percentage by mass is 18-22% for performing 1500-1800W ultrasonic treatment for 30-35 minutes; after ultrasonic treatment, soaking the treated cup in a NaOH solution of 10-12mol / L for 1-2 hours at 60-65 DEG C, and repeatedly and thoroughly cleaning the soaked cup with ionized water till the pH value of cleaning liquid is neutral; finally, soaking the cleaned cup in antibacterial liquid for 20-24 hours, and then drying the soaked cup so as to obtain a product. The preparation method is simple in technology, industrialized production is easy to realize, and the prepared cup is good in comprehensive performance, and is good in bacteriostat effect.

Description

technical field [0001] The invention relates to a stainless steel cup, in particular to a method for preparing an antibacterial stainless steel cup, and belongs to the technical field of stainless steel product preparation. Background technique [0002] With the development of society and the improvement of people's living standards, people's requirements for the quality of life are getting higher and higher, especially after the impact of SARS in 2002 and bird flu in recent years, people's awareness of environmental protection has increased, antibacterial materials is getting more and more attention. [0003] Stainless steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel. The steel grades that are resistant to weak corrosive media such as air, steam, and water, or have stainless properties are called stainless steel; Corrosion) steel grades become acid-resistant steels. Due to the difference in chemical composition of the two, their corrosion resi...
