Problems solved by technology

Iron cookware is easily oxidized and rusted by complex environments such as humidity during transportation and storage after production. To prevent iron cookware from rusting, one of the common methods is to cover the surface of the cookware with a layer of vegetable oil to prevent Humid gas contacts the iron cookware body and rusts. The problem with this protection method is that the coated vegetable oil is easy to oxidize and deteriorate, the anti-rust ability is weak, and the protection ability will be lost in a short period of time. Moist air is easy to penetrate and make the rusty iron cookware
[0003] Another way to prevent iron cookware from rusting is to apply oil to cast iron cookware, and after heat treatment, a layer of black protective film is formed on the surface of the cookware product. The black protective film protects the iron cookware body. What needs to be improved for the black protective film to protect iron cookware is that the salt spray test test time of the protective film formed by heat treatment is generally 15 to 20 minutes, and it is not suitable for the dishwasher test and cannot pass the dishwasher According to the test, its ability to block damp gas is limited, and rust will still appear during long-term transportation or storage. In addition, the appearance of the formed black protective film is not beautiful enough, which does not meet the requirements of current users for a bright appearance.

Embodiment 1

[0032] Clean the surface of the iron pan, remove the stains and impurities, and then dry it. Immerse the iron pan in linseed oil with an oil temperature of 36°C, soak for 3 seconds and then take it out, and then preheat the iron pan in an environment of 160°C for 10 minutes; Transfer the preheated iron pan to a baking furnace and sinter it at 270°C for 20 minutes; after sintering, transfer the iron pan to the cooling chamber and cool it to room temperature. A layer of 30μm thick gold is formed on the surface of the iron pan Protective layer.

Embodiment 2

[0034] Clean the surface of the iron pan, remove stains and impurities, and dry it. Immerse the iron pan in linseed oil and olive oil at an oil temperature of 30°C. The weight ratio of linseed oil and olive oil is 9:1. After soaking for 5 seconds, take it out , Then preheat the iron pan at 150°C for 10 minutes; transfer the preheated iron pan to a baking furnace and sinter it at 265°C for 25 minutes; after sintering, transfer the iron pan to cooling And cool to room temperature, a 40μm thick golden protective layer is formed on the surface of the iron pan.

Embodiment 3

[0036] Clean the surface of the iron pan, remove stains and impurities, and dry it. Immerse the iron pan in linseed oil and safflower seed oil at an oil temperature of ℃. The weight ratio of linseed oil and safflower seed oil is 9:1, soak 3 Take it out after a second, and then preheat the iron pan at 180°C for 10 minutes; transfer the preheated iron pan to the baking furnace and sinter it at 230°C for 25 minutes; after the sintering is complete, put the iron pan Transfer to the cooling chamber and cool to room temperature. A layer of 45μm thick golden protective layer is formed on the surface of the iron pan.

Abstract

The invention discloses a cooker and a method for forming a golden protective layer on the cooker. The method for forming the golden protective layer on the cooker comprises the steps that at least part of the surface of the cooker is covered with vegetable oil, the vegetable oil comprises linseed oil, the cooker with the vegetable oil on the surface is sintered in the environment of 180 DEG C to300 DEG C, and the golden protective layer is formed after the cooker is cooled. By means of the method for forming the golden protective layer on the cooker, the golden protective layer is formed onthe cooker, the surface of the finished cooker is golden yellow, the color is full, uniform and bright, the finished cooker is more fashionable, elegant, healthy and environmentally friendly, the saltspray test time of the golden protective layer is greatly prolonged, and good oxidation resistance, rust resistance and surface protection functions can be achieved for the cooker through dishwashertests, and the antirust property and the long-term protection performance are excellent.

Description

Technical field [0001] The present invention relates to the technical field of cookware manufacturing, in particular to a cookware and a method for forming a golden protective layer on the cookware. Background technique [0002] Iron cookware is a traditional kitchenware, and many families still use iron cookware to cook food. Iron cookware is easily oxidized and rusted under the influence of humidity and other complex environments during the transportation and storage process after production. In order to prevent iron cookware from rusting, one of the common methods is to cover the surface of the cookware with vegetable oil to block it. Moist gas touches the iron cookware body and rusts. The problem with this protection method is that the coated vegetable oil is easy to oxidize and deteriorate, and the anti-rust ability is weak. The protective ability will be lost in a short time. The humid air is easy to penetrate and cause Iron cookware is rusty. [0003] Another way to preven...
