Is the honeycomb nonstick pan coated?
The honeycomb nonstick pan has no coating. Honeycomb non-stick pan is a new type of non-stick pan made of patented honeycomb non-stick technology. The concave-convex texture was etched on the pot wall by German etching process, which solved the problem of non-stick pot coating falling off and realized the physical non-stick of isolation coating. Non-stick pan is a pan that does not stick to the bottom of the pan when cooking, because the bottom of the pan is coated with non-stick paint. Teflon coating and ceramic coating are the most common non-stick properties.
Secondly, there are special craft woks and stainless steel pot. The advent of non-stick pan has brought great convenience to people's lives. People don't have to worry about cook the meat anymore, but they will burn if they are not careful. When frying fish, the fillets will stick to the wall of the pot. This non-stick pan has nothing to do with the appearance of ordinary pan, but a layer of PTFE is coated on the inner surface of the pan, and this popular kitchen utensil is made by using the excellent performance of PTFE.
How to choose a non-stick pan
Selection of coating materials for (1) non-stick pan
The main material of non-stick pan coating is PTFE, which is called PTFE by chemical name. This material is relatively stable and has the advantages of high temperature resistance, low temperature resistance, corrosion resistance, non-stickiness, non-toxicity and so on. And it has very good stability, so it is widely used in all walks of life.
Teflon can withstand high temperatures above 200℃. This material is very stable below 200℃. The highest cooking temperature at home will not exceed 180℃, so the coating of non-stick pan is generally stable. When the coating is intact, the non-stick pan is non-toxic and can be used safely.

(2) Selection of non-stick pan body materials
Non-stick pan body materials include iron, aluminum, stainless steel and alloy steel.
1, iron products are pig iron and wrought iron. Pig iron products are cast, thick and heavy, but have large heat capacity and are not easy to overheat; Wrought iron products are thin and have small heat capacity. Both of them are easy to rust and are corroded by acid and alkali, so their life span is short.
2. The advantage of aluminum products is light weight and fast heat conduction, but the disadvantage is that they will react chemically with food with strong acidity and alkalinity, thus shortening the service life, and its oxidation products make people feel unclean.
3. Stainless steel products have the advantages of acid and alkali resistance, corrosion resistance, high temperature resistance, difficult oxidation and long service life, but the price is more expensive.
4. Alloy products generally have the properties of stainless steel, but the price is higher, and some elements are harmful to health.
(3) Non-stick and easy-to-clean performance inspection of pots and pans
To identify whether the non-stick pan is qualified, we can do a simple non-stick pan test: when the non-stick pan is burned to 1500C to 1700C, put fresh eggs in the pan, turn the pan over until it is solidified, and the eggs can fall freely, which is the qualified product; Otherwise, it is an unqualified non-stick pan.
