Non-stick pan is now a lot of families will choose to buy a cookware, because people in the cooking feel sticky pan is a very troublesome thing, sticky pan after not only not be able to successfully carry out the next dish, and in the final brush will find it difficult to pot on the sticky things to clean down, so to fundamentally solve the problem of sticky pan, only to buy a non-stick pan, non-stick pan does not stick to the reason is because there is a layer of coating.
What is a non-stick coating?
On the non-stick pan, people first concern is the coating, the most common non-stick coating on the market is Teflon. Teflon is the phonetic translation of Teflon, which is a registered trademark used by DuPont on a series of fluoropolymer products. Teflon, also known as "polytetrafluoroethylene", has good resistance to chemical corrosion and aging properties, even with "aqua regia" is difficult to corrode. Products made of Teflon can be placed outdoors in the sun and rain for 20 to 30 years without any damage. Teflon also has an ultra-low coefficient of friction and surface, which makes it difficult for other substances to adhere to its surface. Teflon occupies most of the market for non-stick pan coatings.
Besides Teflon, some other types of non-stick coatings can be found in China, such as ceramic coatings, Japan's Daikin (Dakin) fluorine coatings and the United States of America's Waffle (Whitford) coatings.
Coating: In 2004, the Teflon incident broke out all over the world, in which the main reason is that the main ingredient in the non-stick coating, Perfluorooctanoic acid and its salts (PFOA), was examined as a possible carcinogen. This led to panic. And it is very easy to be scratched by metal utensils, and will decompose and detach at high temperatures of more than 240 degrees. Therefore, countries began to study how to solve the problem.
Penetration layer: South Korea HAPPYCALL products by South Korea HAPPYCALL Co., Ltd. and the Korea National University *** with the success of the research and development, the use of nanotechnology will be nano-nano diamonds and platinum at high temperatures in the infiltration, a simple understanding of the surface of the metal is the micron at the fusion of each other. Do more anti-wear is not easy to delamination and absolutely harmless characteristics.
Non-stick cookware precautions
Non-stick coating although toxic under certain conditions, but as long as the use of non-stick cookware to comply with the precautions or safe.
Non-stick cookware can not make acidic food, PTFE bonding strength is not high, acid easily corrode the metal body, once the body is corroded will expand, thus swelling the coating, resulting in large areas of the coating off. It is understood that much of the food consumed on a daily basis is acidic, including a variety of meats, eggs, sugar, rice and so on.
The use of temperature to be limited to less than 250 ℃, the national mandatory standards, with PTFE as the main raw material, with certain additives composed of PTFE coatings, coated on aluminum, iron plate and other metal surfaces, sintered at high temperatures as a contact with non-acidic food containers of anti-adhesive coatings, the use of the temperature is limited to less than 250 ℃.
Don't use a spatula, be wary of breakage, the use of a spatula, easy to damage the coating of the non-stick pan, so that toxic coatings into the dish, harmful to health, the use of non-stick cookware should also be more to check whether there is no coating off the phenomenon, so as not to cause serious consequences.
In the above article, we introduced you to some information about the non-stick pan, we are in this article mainly for you to introduce the knowledge of the two aspects of the non-stick pan, you can see that we will be divided into two parts of this article to start for you to explain, first of all, in the first part of the first part of the first part of the first part of the first part of the first part of the first part of the first part of the first part of the first part of the first part of the second part of the article we introduced the non-stick pan The second part of the article we introduce the use of non-stick precautions, because some users have concerns about non-stick coating, after reading these should be able to understand.
