Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a device for testing scratches on non-stick coatings of kitchenware. Background Art
[0002] Cookware and bakeware are frequently used kitchen items. To facilitate cooking and prevent food from sticking, they are coated with a nonstick coating. While existing nonstick coatings have made significant advances in environmental safety, scratches, spots, and even peeling can directly impact performance and potentially negatively impact food safety. Therefore, strict quality control of the coating is crucial during the manufacturing process. In addition to rigorous production controls, sampling and testing of finished products is also an essential quality assurance measure.
[0003] For the average consumer, it's difficult to determine whether a product's non-stick coating is susceptible to scratching or nicking simply by looking at it. A dedicated test to evaluate the coating's scratch resistance, with direct labeling, would provide consumers with an objective and visible basis for their choices. It would also provide manufacturers with a robust basis for quality inspection and improvement, potentially preventing losses. Utility Model Content
