Manufacturing technology of stainless steel enamelled cup

Abstract

The invention discloses a manufacturing technology of a stainless steel enamelled cup. The manufacturing technology comprises the following steps of: step 1. manufacturing a stainless steel cup body;step 2. removing oil on the inner surface and outer surface of the cup body manufactured in step 1; step 3. performing abrasive blasting on the inner surface and outer surface of the cup body after completing oil removal on the cup body; step 4. spraying or enameling a first layer of nano-enamel glaze on the inner surface and outer surface of the cup body after completing abrasive blasting on thecup body; step 5. performing primary sintering; step 6. cooling; step 7. spraying or enameling a second layer of nano-enamel glaze on the inner surface and outer surface of the cup body; and step 8. performing second sintering. Enamel is sprayed on the surface of stainless steel through the manufacturing technology, so that the produced product has the advantages of stainless steel products, meanwhile overcomes the defects of the stainless steel products, and has strong safety performance and attractive appearance.

Description

technical field [0001] The invention relates to the technical field of cups, in particular to a manufacturing process of stainless steel enamel cups. Background technique [0002] Most of the existing cups, including thermos cups and water cups, are made of stainless steel or ceramics. The defect of the cups made of stainless steel is that the thermos cups made of stainless steel are used for storing hot water for a long time. The nickel in the water will dissolve in the water. Drinking this kind of water for a long time will cause diseases such as senile dementia. Secondly, when using stainless steel cups to hold hot water, there will be a metallic taste when drinking. In addition, stainless steel cups are not easy to clean, and liquids such as coffee, etc. It is easy to adhere to the wall of the cup, and the defects of the ceramic cup are: no heat preservation and no resistance to falling; enamel is an inorganic glass enamel coated and fired on the surface of the metal bas...

[0002] Most of the existing cups, including thermos cups and water cups, are made of stainless steel or ceramics. The defect of the cups made of stainless steel is that the thermos cups made of stainless steel are used for storing hot water for a long time. The nickel in the water will dissolve in the water. Drinking this kind of water for a long time will cause diseases such as senile dementia. Secondly, when using stainless steel cups to hold hot water, there will be a metallic taste when drinking. In addition, stainless steel cups are not easy to clean, and liquids such as coffee, etc. It is easy to adhere to the wall of the cup, and the defects of the ceramic cup are: no heat preservation and no resistance to falling; enamel is an inorganic glass enamel coated and fired on the surface of the metal bottom blank

[0003] However, the process of enamelling on the surface of stainless steel cannot be realized in the prior art. Therefore, the application proposes a manufacturing process of a stainless steel enamel cup, which can attach enamel to the surface of the stainless steel base to make a cup that can keep heat and is safe. , and beautiful cup body
