Description
Technical Field
The invention relates to a cooker, in particular to an environment-friendly non-stick pan and a preparation process thereof.
Background
In the existing non-stick pan, a polytetrafluoroethylene non-stick coating or a ceramic non-stick coating is mostly coated on the inner surface of a metal pan, most of the non-stick coatings are synthesized by chemical substances, various chemical additives are added in the production and processing processes, the safety of the chemical substances is in question, and for example, the potential carcinogenic hazard of PDFOA (ammonium perfluorooctanoate and salts thereof) to human bodies is widely reported. There are other chemicals whose potential harm to the human body is not fully understood because the exact mechanism by which they act on the human body has not been discovered. The non-stick coating on the pan body is not in a stable state, and the non-stick coating is easy to chemically react with various acidic and alkaline foods (such as tomatoes) and seasonings (such as salt, vinegar, sauce and the like). In addition, the high temperatures used during cooking tend to break them apart and release harmful substances. More importantly, the non-stick coatings have short service life and poor wear resistance, and can be abraded within 3-6 months, and most of the non-stick coatings peeled off from the inner surface of the pot are mixed into food and ingested by human bodies in the cooking process. If the human body takes in the chemical substances for a long time, the chemical substances can cause extremely far-reaching potential harm and influence on the human health, the chemical substances are deposited and accumulated in the human body after being absorbed by the human body, and once the chemical substances are induced, the chemical substances can be intensively erupted, so that various body diseases such as canceration and the like can be caused. Therefore, the current non-stick cooker product cannot meet the mainstream of times when modern people pursue green natural nutrition, health, energy conservation, sanitation, environmental protection, convenience, practicability and low cost. People also pay disastrous health costs when pursuing convenient kitchen cooking life, and some people are even afflicted with the diseases.
