What material is the inner liner of the hot water kettle?
What material is the inner container of the kettle? The use of kettles is very common. Many friends who like to drink Kung Fu tea will bring their own electric kettle, which not only can boil water quickly, but also has many advantages such as safety, convenience and heat preservation. What material is the inner container of the kettle?
What is the material of the inner container of the hot water kettle? 1 1. According to materials, there are stainless steel alloy lining, titanium alloy lining and coated stainless steel lining. The coating is usually enamel powder. Enamel is divided into dry bath process and wet bath process. Of course, the best electric water heater liner is titanium alloy liner, which is adopted by general international brands. The common brands of electric water heaters in China all adopt enamel technology.
2. At present, domestic electric water heaters are divided into stainless steel liners and enamel liners.
What is the coating of the thermos container?
The thermos is plated with silver. If the inner liner is broken, the silver film will not volatilize.
The inner container of thermos bottle is made of double-layer glass, and both layers of glass are plated with silver, which can reflect heat rays back, thus cutting off the path of heat radiation. The vacuum between two layers of glass in the inner container destroys the convection and conduction conditions.
The bottle cap is made of cork, which is not easy to transfer heat, to block the passage of convective heat transfer. Through these three functions, heat can be preserved for a long time.
Among them, silver plays an important role. Its melting point is 96 1.93℃ and its boiling point is 22 12℃. Its physical properties are still very stable, and the ordinary ambient temperature is not enough to volatilize silver into the air, so it can be used safely.
Silver ions and compounds are toxic to some bacteria, viruses, algae and fungi, but almost harmless to human body. At the beginning of the 20th century, people also put silver coins in milk to extend the shelf life of milk. The sterilization mechanism of silver has been debated for a long time, and there is no conclusion so far.
Although silver is almost harmless to the body, long-term exposure to silver metal and non-toxic silver compounds can also lead to silver deposition. Because the body pigment changes, the skin surface will appear gray-blue Although non-toxic, it will still affect the appearance.
What is the material of the inner container of the hot water kettle? 2 1. Plastic thermal insulation liner: All hot water kettles with plastic thermal insulation liner only have thermal insulation function, and the thermal insulation time is only about 3 hours.

The inner container of ceramic thermos cup is a kind of less commonly used material, which is relatively rare in the market.
3, purple sand insulation liner: purple sand insulation liner kettle, this material has insulation function, some better purple sand also has health care and conditioning functions. The purple sand liner is often matched with the stainless steel shell, which can improve the service life of the purple sand cup.
4. Glass insulated liner: The kettle with glass insulated liner is a relatively healthy kettle, but it is not resistant to falling. The substance of glass is relatively stable and will not leak impurities because of boiling water. Glass cups are easier to clean, but not easy to carry around.
5. Stainless steel insulation liner: The insulation pot of stainless steel insulation liner generally adopts food-grade 304 stainless steel, which contains some iron, but some inferior stainless steel will also release some toxic heavy metals.
