The appearance of non-stick pan provides conditions for healthy cooking with less oil, and also makes cooking utensils more convenient to clean. However, in the non-stick frying pan into life at the same time, the safety of its coating has never been questioned.There are two main coating processes for non-stick frying pans: one is the traditional coating process, Teflon coating (PTFE); The second is Sol-Gel process (SOL-gel), which is often used in the production of ceramic nonstick layer. At PRESENT, THE non-stick pan on the market is all kinds of, and the quality is uneven, how to choose, how to use and whether there is a health risk in their use, it is worth our discussion and learning. Teflon: Most non-stick pan weapons Non-stick frying pans and the coating materials they use date back to World War II. The earliest nonstick material was PTFE, now known as Teflon, which was discovered by DuPont engineer Roy Plunkett in 1938.Teflon has a high corrosion resistance, most of the strong acids and alkali (including aqua rega and fluoroantimonic acid), strong oxidants and reducing agents are unable to deal with it, so it has another nickname -- plastic king. Teflon also has an ultra-low coefficient of friction and surface energy, making it difficult for other substances to attach to its surface. With these absolute advantages, Teflon has occupied most of the market for non-stick pan coatings and is the leader in the cookware field. Teflon non-stick pan Common non-stick pan in daily life, in addition to the special instructions are with ceramic or other coating, are basically using PTFE to do non-stick coating.The traditional process of PTFE generally includes adhesive or resin, dye, non-stick components, reinforcing agent, water or solvent carrier; The quality of non-stick pans depends on the number of layers in the process and the materials used in each layer. Generally speaking, the more the process level of non-stick pan, the better the performance, the longer the service life, but the price will be more expensive.For example, the middle non-stick coating production process usually goes through three layers of treatment, the first is the bottom layer with adhesive base, strengthen the adhesion between the non-stick layer and the metal; Secondly, the use of dyes and filling materials to cover the bottom, so that the metal is not easy to expose, and can increase the thickness of the material; The last layer is mainly made of PTFE material to release non-viscous energy. The three-layer non-stick pan made in this way is suitable for daily use. If properly maintained, the service life is also considerable. Sol-gel: The secret ingredient of ceramic non-stick pan In recent years, in addition to Teflon, other types of non-stick coatings are also developing. Dakin fluoride coatings in Japan, Whitford coatings in the United States and ceramic coatings are gradually accepted by the market.Aside from Teflon non-stick pans, it has to be mentioned that ceramic ...

Feature 1.Non viscous: almost all substances are not bonded with PTFE coating. Very thin films also show good non-adhesion properties. 2.Heat resistance: PTFE coating has excellent heat and low temperature resistance characteristics. Short time can withstand high temperature to 300℃, generally between 240℃~260℃ can be used continuously, with significant thermal stability, it can work at freezing temperature without embrittlement, at high temperature does not melt. 3. Sliding: PTFE coating has a low coefficient of friction. The friction coefficient changes when the load slides, but the value is only between 0.05 and 0.15. 4. Moisture resistance: PTFE coating surface does not touch water and oil, production operation is not easy to touch the solution, such as sticking a small amount of dirt, simple wipe can be removed. Short downtime, save man-hours and improve work efficiency. 5. Wear resistance: under high load, with excellent wear resistance. Under certain load, it has the dual advantages of wear resistance and non-adhesion. Application Area Ptfe can be extrusion or extrusion processing molding; Used in, high temperature wire, can also be first made into film and then cut into the shaft packed PTFE belt, used for the production of high frequency cable, directly made of water dispersion liquid, can be used for coating, impregnation or made into fiber. Ptfe in atomic energy, defence, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textile, metal surface treatment, pharmaceutical, medical, food, metallurgical smelting and other industries widely used for high and low temperature resistance, corrosion resistant materials, insulation materials, anti-sticking coating, etc., make it become the irreplaceable products.

If you've ever used a non-stick pan, you know how good it is.You don't need any cooking skills to get a spoonful of rice without the rice crust and a full fried egg for breakfast. It also cooks healthier with less oil and less paste. However, in recent years, "non-stick pans are toxic" claims abound; Also many people see the bottom of the non-stick pan is scratched, showing mottled lines, always worry about coating toxic. Are non-stick pans really toxic? Non-stick pans are controversial because of their coating. But the reason why can "not stick", with "Teflon" on the surface of the uneven gap filled, forming a really smooth "film". Teflon is a polymer made of tetrafluoroethylene as a monomer polymerization, with good heat resistance, cold resistance, acid resistance, alkaline resistance, strong stability, almost not by any material erosion, so it is also known as the "plastic king". Because Teflon carries labels such as "polymer" and "plastic", it is easy to think of toxic and carcinogenic, which is also an important reason for the spread of the "non-stick frying pan carcinogenic". In fact, teflon itself isn't toxic. But in the production of teflon, some bad manufacturers use a processing aid called PFOA (ammonium perfluorooctanoate), which has been linked to thyroid diseases, high cholesterol, ulcerative colitis and other diseases, and has a certain cancer risk. But PFOA has been banned in most countries, including China. Therefore, we buy in the formal mall, in line with the national standard Teflon coating non-stick pan, in fact, is very safe. In addition, the melting point of Teflon is about 327℃, so it can withstand a high temperature of 300℃ in a short time, while it can be used for a long time below 260℃. Generally, the temperature in cooking cannot reach this level. In life, the temperature of the oil used for stir-frying and refrying is about 70 percent hot, and its temperature value is 190℃ - 240℃; After cooking pickled cabbage fish and boiled vegetables, the oil temperature is nine to ten percent hot, and the temperature is between 250℃ and 300℃. It can be seen that the safety index of Teflon coated non-stick pan is still very high under normal cooking temperature. At present, most of the non-stick pan, with a long time will inevitably appear coating off or be scratched phenomenon, at this time can also be used? Some experts said that teflon properties are very stable under normal use, and even if you ingest a small amount of fallen coating particles, they will generally be excreted by the human body, so it does not seriously affect your health. But when the coating falls off, it does pose a health risk: on the one hand, the food tends to stick and become burnt, which is not only difficult to clean, but also prone to produce more harmful substances. Under normal circumstances, the normal service life of non-stick pan is 1-2 years, but when its non-stickiness disappears, even if the coating is not damaged, it should be replaced in time...
