We often use non -stick pots. Many people often fry and boil, but I do n’t know why it is not easy to stick to the burnt food. After all, it is closely related to us. We should understand it. Therefore, XiaobianTake everyone to analyze, why isnt it easy to stick to the pan without sticking to you.
What is the principle of non -stick coating
The surface of non -stick pan is usually covered with a layer of coatings. Non -stick coatings are special coatings that are not easy to be adhered to or sticky by other sticky substances on the surface of the coating surface.This coating has been widely used in household appliances, cooking kitchenware, automotive, machinery, chemical industry and other industries due to the low surface of its coating, small friction coefficients, and easy -to -sliding.
Most of the coatings are Teflon, which is the so -called polytimononythery.So why does it make the pot not stick?
The structure of polytrafluorolytin is the high molecule of the main chain all -carbon, and each carbon atom is connected to two fluorine atoms.Due to the super -strong electrical negatives of fluorine, the carbon fluoric keys are extremely stable.Therefore, polytetrafluoroethylene shows a large reaction inertia.The molecules in food are also difficult to react with polytetrafluoroethylene.Even the most lively halogen fluorida cannot react with polytetrafluoroethylene.The super -strong electrical negativeness of fluorine means that other molecules are excluded when they encounter polytrafluoroethylene.These reasons are the principle of "non -stick" of non -sticky pot.
What is the principle of no coating without sticky pan
The basic film for non -stick coatings is fluorine resin and adhesive.The choice of fluorine plays a vital role in the non -stick performance of non -stick coatings.There are many types of fluorine resin. Among the many fluorine resin, the friction coefficient of polytetrafluoroethylene (PTFE) is the smallest, so PTFE is the preferred fluorine resin for non -stick coatings.
At present, the domestic non -sticky pot manufacturing technology is still backward, and some are not stained with poor effects, and it is easy to fall off after a long period of use.At present, some American pot brands adopt deepening and hard -covered technology to make non -stick pots. They are injected with polymer containing non -sticking ingredients on the surface layer and inner layers of the pot.Do not stick to the coating, and this polymer is actually dissolved with the surface of the pot, penetrating into the pores of the metal, and durable.
Which is not sticky
At present, 70%of the pots sold in China are aluminum alloy non -stick pots. The benefits of this pot have good thermal conductivity compared with the iron pot, and it can be used on the electromagnetic cooker. It is more convenient.Very simple.At present, the coatings of various materials on the market are not sticky, but they all have advantages and disadvantages. For example, Korean products generally use ceramics or ceramic crystals. The disadvantage is that it is easier to drop the layer. Because the ceramics are relatively crispy, the most affordable ones are still the most affordable ones.Teflon, which was said to be poisonous in the past, in fact, this is a misunderstanding, because the soluble point of Torraon is very high, and generally the normal cooking will not make Teflons toxicity volatilize, but if it is dry for a long time, it will be burned for a long time.It is easy to dissolve in TMF, just like we generally use other products. If it cannot be used correctly, it will produce adverse consequences. Therefore, as long as it is correctly used according to the instructions, it will not affect the body.In addition, we must establish a concept, that is, any product has a service life, not that the iron pot we used to use before can be used as long as the bottom of the pot is not burned.It is normal to produce the phenomenon of reduced the effect of non -sticky pot and non -sticky effect. This is normal.
Also, everyone should pay attention to the detailed information of the product when buying non -stick pots, instead of just looking at the price, because the pot and the bottom of the pot are the main part of non -stick pot. At present, the non -stick pot on the market mainly has a pull -up pot.The advantages of the die -casting pot are relatively uniform, the pot body is stronger, and the pot wall of the pot is thinner, lighter, and cheaper. The disadvantage is that the heating is uneven and easy to deform.The other is the bottom of the pot. At present, there are three kinds of pot bottoms on the market. One is a normal bottom. It can only be used on the gas stove. The price is cheap. The other is the bottom of the pot that everyone can see.Like a hole, this base can be used on the gas stove and induction cooker, but the disadvantage is that the heat conduction effect is poor, the price is moderate, and there is a heating to the bottom (the bottom of the pot is flat, not like a cold ground.Small holes) The best thermal conductivity, the fastest heating speed. If it is the best combination with the die -casting cooker body, the price is a little higher than the cold ground.
