Hong Taro's weapon against Big Big Wolf-non-stick pan, is the topic we are going to discuss today. Since ancient times, no matter what pot, you have to stick something. The advent of non-stick pan has brought convenience, but has it also brought trouble? My little brother's "Cold Eyes" series has been more than 20 episodes. Cold eyes are not cold, but "static". Therefore, if we face the proliferation of fake health care and fake Chinese medicine today, we all need a pair of cold eyes!
Abstract:
1, commercial society, the existence is not necessarily reasonable!
2, the secret of non-stick pan non-stick coating!
3. Where did the non-stick pan fall from?
4, the first choice for the pot is the raw iron pot!
Incandescent light bulb, that is, ordinary light bulb, is an epoch-making invention. Before there were no light bulbs, we could only use candles, oil lamps, torches and a lot of fireflies for lighting at night. Of course, we can also use the method of poaching (only for reading).
With incandescent light bulbs, it is very convenient. When you pull the light rope, the light will come on. Hehe, my little brother also used a light rope to pull the light. If you are younger, I'm afraid you think that the light switch is always on and off the wall. At that time, we were most afraid of pulling the light rope. The light was on and we had to connect a rope.
After the invention of incandescent light bulbs, scientists discovered the shortcomings of incandescent lamps, such as high power consumption and limited brightness, so they invented "fluorescent tubes". However, the manufacturers of incandescent bulbs quit and invested so much money in infrastructure. How can they recover their costs, plus huge profits? What did we do? As a result, incandescent lamp manufacturers bought out the patent right of "fluorescent tube". After several decades, incandescent bulb technology was unprofitable, so they switched to "fluorescent tube"! The earth has wasted countless electric energy for no reason, because businessmen are mercenary!
However, it is also beneficial. After all, fluorescent tubes are one of the important drivers of myopia outbreak. Therefore, the buyout of incandescent lamp merchants has led to the outbreak of myopia for decades.
What do we want to tell you by telling this example here? Is to tell you a word, "what exists is not necessarily reasonable"!
There are too many related cases, such as thalidomide, tetracycline, old Contek, norfloxacin which is not suitable for children, sulfur smoked Chinese medicine and so on. Those who went public for a long time were listed through legal channels, which seemed reasonable, but in the end they were forced to withdraw from the market at the expense of the health of countless people!
So some people will say, since non-stick pans are all produced and sold, why is it unreasonable? Look at the above case and you will understand! So, today, little brother will take you to appreciate the non-stick pan carefully!
Non-stick pan really doesn't stick oil, except oil. This is an indisputable fact! You can see with your eyes and touch with your hands, but where is the secret of non-stick oil?
Mystery is the "mysterious coating" in the pot. This "mysterious coating" is called "PTFE" and is known as "the king of plastics". There is also a foreign language called Teflon or Teflon, and the English name is Teflon. This coating has the lowest friction coefficient and the lowest surface energy among all plastics.
This is the coating of most non-stick pan liners we can buy! A good pot must be hung with a plastic liner! Even the king of special plastics is a kind of plastic that has not escaped from the circle.
Teflon, the temperature range is within 260, so many people think it is safe! Little brother doesn't want to say too much. Let's take a look at the list of carcinogens cited by the US Food and Drug Administration from WHO on 20 17! ! !
The 385th item in the list of three carcinogens is Teflon (polytetrafluoroethylene)!
The three carcinogens mean that they do not rule out carcinogenicity, but they do not rule out carcinogenicity! What do you mean? The second sentence is the key, that is, Teflon (PTFE) does not rule out that it will not cause cancer!
We quoted a scientific paper published in Physical and Chemical Inspection, Volume 52, 20 16. Liu Lixia's article "Quality Analysis of Non-stick Pot Products" mentioned that
"The samples of this test were all purchased from the circulation field in Jiangsu Province, with 42 batches covering the non-stick pans of mainstream brands on the market! For all samples, refer to the national standard QB/T 232 1- 1998 ".
"Among them, 20 batches meet the national requirements, with a coincidence rate of 47.6%. Except for two batches of imported non-stick pans, the pass rate is 100%, and the other domestic batches are all unqualified in different batches. "
"In addition to imported brands and domestic mainstream brands using Teflon coatings, accounting for 76.2%, others use polyester coatings and other coatings."
"The unqualified rate of coating thickness and corrosion resistance is 42.9% and 15.2%."
I believe this paper reports the present situation of non-stick pan authoritatively and objectively. If the pass rate is 100%, it goes without saying that it is all problematic data. My little brother just wants to say here, why does a good pot have a "plastic" coating? Is it so much trouble to brush a pot? How can a pot that needs continuous high temperature always be below 260? Once it is exceeded?
Let's take a look at the conclusion of the scientific and technological paper "The Status Quo and Trend of PTFE Materials Related Standards" published in Plastic Industry from 2065438 to April 2004. The following is a screenshot.
The paper admits that although China is a big producer, there is still a big gap between China and foreign countries in terms of technology and products, especially in the research of relevant standards and the internationalization of standards!
You got it?
What does "big gap" mean? Is it equivalent to disqualification?
Whose non-stick pan won't fall off? Really? Certainly not, or not used much. After all, the coating is only 0.25 micron (1 mm = 1000 micron, 0.25 micron =0.00025 mm), so the non-stick pan will fall off after a while, right?
Aha, have you thought about a question? Where did it fall off? It must be in the dish! Where did the food go? It must be in your belly!
What does it mean to be covered with ultra-micro "PTFE" falling off? In cooking, what does it mean that volatiles come out from the fire and the bottom of the pot?
Do you remember the incandescent light bulb at the beginning of the article? Some mistakes, the merchants know! But it will be committed!
In fact, there is no need for a non-stick pan at home, which has nothing to do with my brother's half a dime!
However, little brother wants to say something from the heart!
My little brother never said that non-stick pans will definitely cause cancer, but since the advent of non-stick pans, cancer has been on the rise. ......
Thank you for watching, be healthy, adjust your physique, and join the team of "physical recuperation"!
