FUNCTIONAL CONSIDERATIONS FOR TREATING NONSTICK COATING HOUSEHOLD COOKWARE

The home cooking utensil industry has developed in the recent period in a clear way, which has led to the multiplicity of raw materials and functions of these pots, and in addition to that, many surface treatment processes with different functions have developed for the process of preparing and preserving foods, and among the coatings that have spread in the recent period was what is known as non-coating Nonstick, which is used to paint the inner surfaces of cooking utensils, especially those that have direct contact with foods. It has been used for many materials such as aluminum, its alloys, iron and its alloys. Non-stick coatings in the past were based on Teflon compounds (Tefal) as one of the most important coatings. The inner surfaces of cooking utensils, especially those used in the preparation of certain foods such as baked goods, desserts and cakes. And other foods that can stick to food, enamel coating and anodizing coating were made with thick layers of non-stick coatings, which were of a lower degree than the quality of Tefal in resisting food sticking, then non-stick coatings developed and what is known as ceramic coating appeared, especially applied in a way. Sol-Gel, which is considered an advanced non-stick coating, is suitable for most of the raw materials of cookware for preparing different types of food. The multiplicity of non-stick coating layers leads to an essential need to direct the user to choose the best non-stick layers that are safe to perform their functions.
