What is the principle of nonstick pans? Does the coating of nonstick pans cause health effects?

In general, the coating of this non-stick pan is not harmful to the human body, but if it is not used properly, there may be certain toxic substances. The main raw material for non-stick pan coatings is PTFE. According to the national mandatory standards, with PTFE as the main raw material, inhaling the gas produced by the overheating of the coating can cause temporary cold-like symptoms.

It is suitable for metal surfaces such as aluminum and iron plates. After high-temperature sintering, it is used as an anti-stick coating for non-acidic food containers, and the use temperature is limited to less than 250 degrees. While the performance of non-stick pans is good, this non-stick pan also has its own drawbacks - Teflon is a typical polymer with low strength and hardness, making it feel soft, weak and particularly delicate.

Therefore, this non-stick pan can only be used with a wooden or bamboo spatula, and metal objects such as steel wool balls cannot be used for cleaning, otherwise it will lose its "non-stick" character.

There is no health hazard during normal use of non-stick cookware. Of course, if you don't stick to Teflon, which is not a substandard pan material, it is difficult to say how safe it is, however, no matter what kind of pot you use to cook it, or if the cooking oil is too hot, the carcinogenic toxic gases will be released from the oil smoke. Therefore, avoid using excessively high temperatures to prevent smoke from emitting four times.

It is also important to ensure adequate ventilation.

The coating contains four harmful substances, namely ethylene glycol ether, amino paint, anti-corrosion coating, solvent toluene, the first ethylene glycol ether and its ester solvent coating, which directly has a killing effect on the human body, as long as people are exposed to it for a long time, the heavy ones will damage the blood and lymph, and the more serious ones will also have great harm to the reproductive system.

The second is the paint with amino paint, if you recognize this paint to brush the door, brush the window, passers-by can smell it, sometimes the smoked people will be dizzy, unable to open, the harm is obvious.

The third type of anti-corrosion coating sometimes requires some additional functions, such as the coating used by the ship, which has to add some toxic substances because it requires the killing of seaweed. For example, the addition of heavy metal substances can poison some workers who are close to them for a long time.

The fourth type of paint with solvent toluene, which will not be noticed in the short term, but will be exposed to it for a long time and slowly accumulate toxins. As a result, the body is unwell, there is a feeling of being dumb and eating coptis, and when we accumulate more and find the problem, it will be too late.

The principle of non-stick pan is to add the chemical elements of plastic, and he can fry when non-stick pan. However, for the human body, plastic is an inabsorbable substance, which can cause plastic infection.

It will not cause serious effects on the human body. A special material is used. The bottom of the pot has a non-stick coating, and the materials used are relatively good.

The non-stick pan coating is non-toxic.

A common non-stick pan coating is a Teflon coating. Cookware with a Teflon non-stick coating does not change at room temperature to 26 degrees, but when the temperature exceeds 26 degrees, the coating gradually becomes unstable.

However, it is difficult to reach a temperature of more than 26 degrees Celsius during daily cooking, so no toxic substances will be produced under normal cooking.

Non-stick principleMost rice cookers and non-stick pans use coatings, very stable and safe, ceramic coating ** higher, more stable, more resistant to high temperatures, but not too scratch-resistant, no matter what kind of coating, as long as it is qualified, it can be used with confidence, people who have used non-stick pans, know that it is good, Teflon that meets the standards is actually very safe, it is a very good inert material, ** is also cheap, you can try.

Although there are many styles of non-stick pans on the market, there are many opportunities for us to choose, but in fact, this is not the case, it is very difficult to choose, because, many people do not know much about this and have little experience, the Teflon used in non-stick pans will release toxic substances when heated, many housewives reflect that non-stick pans are very easy to use, PTFE has very stable physical and chemical properties at room temperature and under normal conditions, and the main principle of non-stick pans without easy peeling coating is to use non-stick materials (titanium, Diamonds, etc.) penetrate into the entire pot body or make a thicker coating, more wear-resistant, durable, and generally will not appear coated, ceramic non-stick pan, ceramic non-stick pan body is generally aluminum and ceramic coating, relatively lighter, and more resistant to high temperatures.

I believe that most people understand that the reason why this non-stick pan is not sticky is because of the anti-stick coating on the surface of the pot, do not dry boil, do not wait for the oil to smoke before putting in the ingredients, do not use steel wool balls when cleaning, do not exceed the service life, the phenomenon of sticking to the pan reminds you to change to a new pot, the advent of non-stick pan has brought great convenience to people's lives, people no longer have to worry about cooking meat, it will burn if you are not careful, and the fish fillets stick to the wall of the pot when frying fish.

This standard is applicable to the main raw materials, with a certain additives to form PTFE coatings, coated on aluminum, iron plate and other metal surfaces, sintered at high temperature, as contact with non-acidic food containers of anti-stick coatings in comparison, fluorine-containing coatings are more cost-effective, more people choose, the basic film-forming substances of non-stick coatings are fluororesin and binders, non-stick pots are only coated with non-stick coatings at the bottom of the pot, and this polymer is actually dissolved with the surface of the pot, deep into the metal pores, durable.

The non-stick coating Teflon is relatively safe, not only has a good anti-stick effect, but also is safe and non-toxic, and the principle of non-stick pan is to cover a layer of film to isolate the direct contact between the edible oil and the pot body to achieve the effect of non-sticking!

Most of the non-stick pan coatings are Teflon coatings, and the material is PTFE, generally this material is particularly good, and it has passed safety testing, and non-stick pans need to be replaced in about two years.
