What Is The Development History Of Nonstick Pan?
"Pan" has brought great convenience to people's life, people do not have to worry when cooking meat accidentally burned, fried fish fillets stick on the pot wall. The non stick pan and ordinary pot shape and not what relationship is only in the inner surface of the pot - coated with a layer of Teflon, using PTFE thermal properties, excellent chemical performance, easy cleaning performance and non-toxic performance made this popular kitchen utensils. PTFE is known as "the king of plastic has good resistance to chemical corrosion and aging resistance," aqua "is also difficult to corrosion. The aging phenomenon is easy to occur in ordinary plastic products, it looks nice, after 35 years or ten years will crack, even broken, "plastic king" made in the outdoor place, let the sun and rain, there are twenty or thirty years of injury. It is widely used in daily life and chemical industry.
"King of plastic" is also widely used in industrial absorption tower and corrosion resistant container, with the improvement of the "plastic king", its use in modern life, agriculture, industry, national defence and science and technology will become more and more widely. In the western developed countries, non stick pot has long been widely used. In China, the popularity of non stick pan began in 90s, and its unique performance has been recognized by more and more consumers.

The production history of non stick pan in China can be traced back to the end of the 70s. At that time, the Ministry of light industry organized a technical forum on the production of aluminium coating products outside of aluminum production enterprises, scientific research institutions and foreign experts. After the meeting, put forward the problem of developing non stick pot. From this, the domestic more than 10 aluminum product enterprises begin the research and development work of non stick pan. Shenyang aluminum products factory, Guangdong South hardware factory, Shanghai aluminum product factory and Foshan production enterprise have imported foreign coating aluminum products production line from abroad. The annual output is about 20 million, and the export volume accounts for more than 50%.
There are about 50 enterprises producing non stick pans, with an annual output of 100 million. Production enterprises are mainly located in Zhejiang, Guangdong, Shanghai, Liaoning, Jiangsu and other places.
Pot products mainly include aluminum pot, stainless steel pot, iron pot, enamel wok and pan. Each of these pots has its advantages and disadvantages, among which the advantages of non stick pan are most prominent. Here is a comparison of the performances of these pans:
Aluminum is characterized by excellent heat distribution, heat transfer effect is 16 times the stainless steel pot, and the pot lighter. But the easy cleaning, oil for oil smoke.
Stainless steel pot is characterized by poor heat distribution, easy to produce hot spots and burned food. Stainless steel pan body weight, not easy to clean, oil for a long time, easy to smoke.
Iron enamel pot heat distribution is not good, easy to paste the bottom of the pot. This kind of pot is not easy to clean, the surface is easy to break, which leads to the rust of the iron base material.
Iron pot heat distribution is not good, easy to produce hot spots and burned food, the pot weight, not easy to clean, easy to rust, and oil for a long time, soot.
Non stick pot to overcome all the shortcomings of the traditional pot, easy to clean, gently wipe, that is clean. Non stick pot can be easily fried, fried food without sticky bottom, can minimize oil, kitchen clean, less soot. It also helps reduce fat intake and conforms to the modern trend of low fat and low calorie consumption.
Nonstick products according to different functions can be divided into the boiling pot, frying pan, frying pan, milk pot, according to the inner surface of a non stick coating system can be divided into two layers, a layer of system system and three pot system. One layer system refers to the non stick layer made of single coating; the two layer system refers to the non stick layer composed of two kinds of coatings, the bottom layer and the surface layer; the three layer system refers to the non stick layer composed of 3 kinds of coatings: the bottom layer, the middle layer and the surface layer. According to the product surface treatment method, can be divided into enamel, high temperature paint, polishing non stick pot.
