Description
Technical Field
The invention belongs to the technical field of vacuum cups, and particularly relates to an enameling process for an inner container of a vacuum cup.
Background
The stainless steel vacuum cup is a product which is popular with consumers, and the annual production and sales volume in China is huge. There are many factors considered when consumers choose a thermos cup, two of which are: firstly, the vacuum degree of the vacuum cup is the heat preservation performance; secondly, whether the inner container is easy to accumulate water scale or not and is easy to clean. Based on the process and the cost, the two points of the common vacuum cup are not satisfactory.
Disclosure of Invention
In order to solve the problems, the invention provides an enamel process for an inner container of a vacuum cup, which can effectively improve the heat preservation performance of a stainless steel vacuum cup, improve the accumulation condition of scale and improve the cleanliness of the vacuum cup by changing the manufacturing process.
The technical scheme adopted by the invention is as follows: an enamel process for an inner container of a vacuum cup comprises the following steps:
the method comprises the following steps: welding a stainless steel pipe of a cup body with the thickness of 0.4-0.8 mm into the cup body through argon arc welding, polishing the welding part of the cup body, cleaning, degreasing and drying the cup body, and then carrying out inner container sand blasting;
step two: selecting a food-grade standard enamel glaze, adding water and clay according to a formula, blending and grinding to prepare a matrix agent of a glaze slip, and then adding a small amount of an environment-friendly fluxing agent and an adhesion agent;
step three: uniformly coating glaze on the inner container, and then putting the inner container coated with the ground glaze into an oven for drying;
step four: then, the dried inner container is put into a high-temperature furnace to be burnt to over 800 ℃, and the inner container is burnt in the furnace for 2 to 3 minutes;
step five: coating the surface glaze on the liner with the bottom glaze sintered, sintering to over 800 ℃, placing the liner in a furnace for sintering for 1-3 minutes, and taking out after cooling;
step six: polishing to remove the black oxide layer, press fitting stainless steel insole between the inner container of the shell, welding the insole, and then vacuumizing. After the temperature in the vacuum furnace reaches 500 ℃, the glass beads are liquefied, and the vacuum layer is sealed for vacuum.
Cleaning the cup body, rotatably matching the cup cover and checking.
Preferably, the enamel glaze component is a glassy substance of alkali, boron and silicate systems.
Compared with the prior art, the invention has the outstanding and beneficial technical effects that: the stainless steel vacuum cup manufactured by the vacuum cup liner enamel process has the advantages that the liner is coated with a layer of food-grade standard enamel glaze, and the enamel glaze has the characteristics of antibacterial resistance, acid resistance, alkali resistance, non-adhesiveness, high hardness, high wear resistance, strong adhesive force and the like, so that: the closely arranged enamel glaze materials play a role in heat insulation, can enhance the heat insulation effect of the stainless steel vacuum cup and make up for the defect of low vacuum degree; the antibacterial resistance of the enamel glaze enables the enamel glaze of the stainless steel vacuum cup to emit negative ions, thereby effectively preventing tea water from mildewing and bacteria from breeding; the acid resistance and alkali resistance of the enamel glaze can effectively prevent the influence of water quality and tea water in the stainless steel thermos cup on the enamel glaze; the high hardness, high wear resistance and strong adhesive force of the enamel glaze ensure that the stainless steel vacuum cup is durable; the non-stick performance of the enamel glaze can effectively eliminate scale deposit of the stainless steel vacuum cup, is beneficial to cleaning, and improves the cleanliness of the vacuum cup.
Detailed Description
The invention is further described below in terms of specific examples.
An enamel process for an inner container of a vacuum cup comprises the following steps:
the method comprises the following steps: welding a stainless steel pipe of a cup body with the thickness of 0.4-0.8 mm into the cup body through argon arc welding, polishing the welding part of the cup body, cleaning, degreasing and drying the cup body, and then carrying out inner container sand blasting;
step two: selecting a food-grade standard enamel glaze, adding water and clay according to a formula, blending and grinding to prepare a matrix agent of a glaze slip, and then adding a small amount of an environment-friendly fluxing agent and an adhesion agent;
step three: uniformly coating glaze on the inner container, and then putting the inner container coated with the ground glaze into an oven for drying;
step four: then, the dried inner container is put into a high-temperature furnace to be burnt to over 800 ℃, and the inner container is burnt in the furnace for 2 to 3 minutes;
step five: coating the surface glaze on the liner with the bottom glaze sintered, sintering to over 800 ℃, placing the liner in a furnace for sintering for 1-3 minutes, and taking out after cooling;
step six: polishing to remove the black oxide layer, press fitting stainless steel insole between the inner container of the shell, welding the insole, and then vacuumizing. After the temperature in the vacuum furnace reaches 500 ℃, the glass beads are liquefied, and the vacuum layer is sealed for vacuum.
Cleaning the cup body, rotatably matching the cup cover and checking.
The stainless steel vacuum cup manufactured by the enamel process for the inner container of the vacuum cup according to the scheme is characterized in that the inner container is coated with a layer of food-grade standard enamel glaze, and the enamel glaze has the characteristics of antibacterial resistance, acid resistance, alkali resistance, non-adhesiveness, high hardness, high wear resistance, strong adhesive force and the like, so that: the closely arranged enamel glaze materials play a role in heat insulation, can enhance the heat insulation effect of the stainless steel vacuum cup and make up for the defect of low vacuum degree; the antibacterial resistance of the enamel glaze enables the enamel glaze of the stainless steel vacuum cup to emit negative ions, thereby effectively preventing tea water from mildewing and bacteria from breeding; the acid resistance and alkali resistance of the enamel glaze can effectively prevent the influence of water quality and tea water in the stainless steel thermos cup on the enamel glaze; the high hardness, high wear resistance and strong adhesive force of the enamel glaze ensure that the stainless steel vacuum cup is durable; the non-stick performance of the enamel glaze can effectively eliminate scale deposit of the stainless steel vacuum cup, is beneficial to cleaning, and improves the cleanliness of the vacuum cup. The enamel cup has the advantages of cleanness, sanitation, difficult scale formation, convenient cleaning and the like, but the price is high, compared with a ceramic vacuum cup, the stainless steel vacuum cup is weaker than the enamel cup in the aspects of environmental protection, sanitation, cleaning, scale formation and the like, but the stainless steel vacuum cup has low price, so the inner container enamel coating process is adopted by combining the advantages of the ceramic vacuum cup and the stainless steel vacuum cup.
Preferably, the enamel glaze component is a glassy substance of alkali, boron and silicate systems.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
