Abstract

The invention discloses a manufacturing method of an antibacterial stainless steel vacuum cup. The manufacturing method comprises the following steps: (1) cleaning: cleaning and drying a stainless steel vacuum cup; (2) spraying an antibacterial agent: atomizing and spraying a mixed solution of AgNO3 and NaNO3 on the surface of the stainless steel vacuum cup, and drying; (3) performing antibacterial treatment: heating the dried stainless steel vacuum cup containing the antibacterial agent to a high temperature, and carrying out antibacterial treatment; and (4) performing ultrasonic cleaning: and carrying out ultrasonic cleaning and drying on the stainless steel vacuum cup subjected to antibacterial treatment. According to the manufacturing method, in the antibacterial process of the antibacterial stainless steel cup, a salt film completely covers the whole surface of the cup, the ion concentration in the salt film is uniform and consistent in change, and then the complete and uniform tempering and antibacterial effects and no color spots can be obtained; and the prepared antibacterial stainless steel cup is high in strength and relatively good in impact resistance, and has good resistance to escherichia coli and staphylococcus aureus.

Description

technical field [0001] The invention relates to the technical field of surface treatment of stainless steel vessels, in particular to a method for manufacturing an antibacterial stainless steel vacuum insulation cup. Background technique [0002] In the daily life environment, there are various bacteria, fungi and microorganisms, etc., which pose a great threat to human health and even life-threatening; in addition, bacteria can also cause food, medicine, etc. Large economic losses caused a variety of secondary disasters. With the improvement of people's living standards, people pay more attention to the living and working environment, especially the health and hygiene of eating utensils. Among them, the stainless steel vacuum cup is the most commonly used stainless steel vessel in daily life. Therefore, endowing the stainless steel thermos cup with antibacterial function is of great significance to improving people's living standards and promoting the general health level...
