Abstract
The invention discloses a preparation method of an antibacterial plate for tableware, belongs to the technical field of metal rolling, and solves the problem that coating stainless steel and antibacterial heat treatment stainless steel in food contact materials in the prior art generate harmful substances to human bodies. The preparation method comprises the steps that S1, metal titanium with the granular mass fraction being 97% and metal copper with the granular mass fraction being 3% are mixed, and a mixture is obtained; S2, a non-self-consumption vacuum arc melting furnace is adopted for smelting the mixture into an alloy cast ingot, in the vacuum melting process, electromagnetic stirring is adopted for assisting production, heat preservation is conducted for 3-6 h, and then annealing cooling is conducted; S3, the annealed and cooled cast ingot is heated, and two-pass hot rolling is carried out to form a plate; S4, cold rolling and annealing are carried out: firstly removing an oxidation film on the surface of a hot-rolled plate, and performing cold rolling and annealing treatment on the hot-rolled plate for multiple times; S5, solution treatment is carried out; and S6, aging treatment is carried out on the cold-rolled sheet subjected to solution treatment. The alloy plate is smaller in grain size, the tensile strength, the ductility and other mechanical properties are obviously improved, and meanwhile the good antibacterial property is achieved.
Description
technical field [0001] The present application relates to the technical field of metal rolling, in particular to a method for preparing antibacterial plates for dining utensils. Background technique [0002] With the continuous improvement of people's living standards, people pay more and more attention to safety and health. At present, tableware that is in direct contact with food is easy to carry bacteria, such as cups, kettles and other containers are widely used in daily life, which is likely to be caused by bacteria. cause disease. [0003] At present, food contact materials with antibacterial function are also developed, such as coated stainless steel and antibacterial heat-treated stainless steel. The thickness of coated stainless steel is thin, and the wear resistance, corrosion resistance and antibacterial durability are poor, which is harmful to the human body; and antibacterial heat treatment itself Slow heat conduction, high density, easy to produce some harmful...
