Scratch resistance: This is an index to test the ability of the coating to resist scratches by various hard substances and the hardness,aluminum nonstick cookware curing degree and adhesion of the coating itself. Non-stickiness: Non-stickiness is an important indicator of non-stick pan,aluminum nonstick cookware which involves the performance of the coating itself and the curing quality of the coating.
According to the standard,aluminum nonstick cookware wipe the surface of the non-stick coating with a soft cloth with vegetable oil, wash it with warm water and detergent, then wash it with water,aluminum nonstick cookware dry it, and perform an omelette test to identify the non-stick pan non-sticky Pros and cons.
Why can't non-stick pans make acidic food? Professor Guan Congsheng, an expert in fluoride,aluminum nonstick cookware the Deputy Secretary-General of the Non-metallic Materials Committee of the Chinese Society for Corrosion and Protection,aluminum nonstick cookware and the director of the Institute of Chemical Engineering of Shandong University, said: "Polytetrafluoroethylene has a congenital defect ,
That is, its bonding strength is not high, the non-stick pan is not completely covered with the PTFE coating,aluminum nonstick cookware and there are always some parts of the metal surface exposed. Acidic substances are easy to corrode the metal body,aluminum nonstick cookware and once the body is corroded, it will expand, thereby expanding the coating. Open,aluminum nonstick cookware causing the coating to fall off in a large area.
The relevant standards of the Ministry of Health are based on this principle. "Professor Guan also believes that, "The coating is mainly used for anti-sticking. It is only sprayed with a thin layer,aluminum nonstick cookware and the combination is not strong. It is definitely not possible to use a shovel to cook. "
