Method for testing corrosion resistance of inner container of electric rice cooker

Abstract

A method for testing the corrosion resistance of an electric rice cooker liner, comprising the steps of disposing a salt water containing 10% NaCl on a balance, placing a test sample on a heating furnace, adding the configured 10% NaCl salt water, and the amount of the salt water should be No less than 1 / 2 of the total volume of the container, turn on the heating furnace to keep the brine solution in a slightly boiling state, add water every half an hour or so in the experiment to ensure that the experimental brine is not boiled dry, continuous cooking for 6 hours is a cycle, and change the brine every 24 hours After each cycle, wash with a detergent solution at about 55°C to 65°C, then rinse with clean water, and finally dry with a clean soft cloth, check for defects with the naked eye, and boil salt water until the test sample shows blisters or other defects. obvious defects.

Description

technical field [0001] The invention relates to a method for testing the corrosion resistance of an inner container of an electric rice cooker. Background technique [0002] The rice cooker with a general alloy aluminum liner is more common in the market now. The thickness of this liner is generally below 1.2 mm, and the surface treatment technology mostly adopts ordinary non-stick coating. This kind of liner is generally very effective at the beginning, no crust, and will not stick to the pan, but after a long period of high temperature, it is easy to deform, and the non-stick coating on the surface is easy to fall off after brushing. Seriously, the aluminum layers exposed after these shedding coatings and coatings are easy to be mixed into food will have adverse effects on the human body. Another common one is the rice cooker made of stainless steel, which is more expensive than the inner tank made of alloy aluminum. There is no need to worry about the peeling of the non...

AI Technical Summary

Problems solved by technology

The rice cooker made of stainless steel does not have to worry about the peeling of the non-stick coating, but the cleaning of the stainless steel inner pot is really troublesome, and it is often difficult to remove the crust left after cooking
