Embodiment Construction

[0017] The stainless steel thermos cup of the manufacturing method of the ceramic thermos cup is made of 0.3-0.5 mm thick stainless steel sheet or tube to make the inner tank and shell of the thermos cup, and the cup body is welded by argon arc welding, and then the welding part of the cup body is polished , Clean and degrease the cup body. Vacuuming is then carried out. Then the inner tank of the cup is coated with a layer of ceramics, the process is:

[0018] The first step: clean and dry the inner liner of the cup body;

[0019] Step 2: Choose a food-grade standard ceramic paint, and evenly spray a thin layer of ceramic paint on the inner surface of the cup body;

[0020] Step 3: Put the cup with ceramic coating on the liner into an oven or a drying tunnel to dry.

[0021] Clean the cup body, press it into the bottom of the cup, screw on the cup lid, and inspect.

Abstract

The invention relates to daily hardware, in particular to a manufacturing method of a ceramic vacuum cup. A layer of ceramic is applied to the inner container of a stainless steel vacuum cup, so that the thermal insulation performance of the stainless steel vacuum cup is effectively improved, water scale deposition is avoided and the cleanliness of the vacuum cup is improved.

Description

technical field [0001] The invention relates to daily hardware, in particular to a method for manufacturing a ceramic thermos cup. Background technique [0002] Stainless steel thermos cup is a kind of product that is deeply loved by consumers, and the annual production and sales volume in the country is very huge. There are many factors that consumers consider when choosing a thermos cup, two of which are: one is the vacuum degree of the thermos cup—the heat preservation performance; the other is whether the inner tank is easy to accumulate scale and whether it is easy to clean. Due to the limitations of craftsmanship and cost, the two points of general thermos cups are not satisfactory. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for manufacturing a ceramic thermos cup. By changing the manufacturing process, the thermal insulation performance of the stainless steel thermos cup can be effectively improv...
