316 material of water cup safety
316 material of water cup safety, the weather is gradually cold up, I believe that many of the small partners of the thermal insulation cup are soaked in goji berries to maintain health, 316 material of water cup is not safe, I look at the 316 material of water cup safety with you.
316 material of water cup safety 1Safety.
316 stainless steel is a stainless steel, due to the addition of Mo elements, so that its corrosion resistance, and high temperature strength has been greatly improved, high temperature resistance can reach 1200-1300 degrees, can be used in harsh conditions.
316 stainless steel is also the main user of the food industry and surgical equipment, 316 stainless steel also has a characteristic, is basically no thermal expansion and contraction phenomenon. Note that the insulation cup can not be used in the pot with cooking, otherwise reduce the insulation performance, and will have damage to the appearance of the paint.

Note: Attention: Attention:
These are the most important things that you need to know. strong>
1, can not be a long time to hold a strong acidic food (such as meat products, melon, soy products, potato products, sugar, beer, etc.), to prevent chromium, nickel and other metal elements dissolved.
2, can not be a long time to hold salt, soy sauce, hot soup and so on. These foods contain many electrolytes, long time holding, stainless steel will be like other metals, and these electrolytes electrochemical reaction, so that harmful metal elements precipitation.
3, can not use stainless steel cups pots for a long time to hold a high decoction of soup, in the continuous heating, it is easy to chemical reaction with some components of stainless steel, so that the effect is reduced, and may even generate some toxicity of the larger substances.
4, avoid large fire cooking food. Because the stainless steel thermal conductivity is small, the bottom of the slow heat dissipation, such as too much fire, can make the bottom of the stainless steel pot burnt, lumps.
316 material cup safety 2Harmless
316 stainless steel insulation cup itself is safe and hygienic, mainly in daily use to pay attention to some of the things are not suitable for soaking insulation cups. 304 stainless steel is only suitable for food-grade, 316 is higher than the 304 level. 316 is mainly used for medical equipment, of course, can also be used in one or two types of tableware, and can be used in a number of different ways. Can be used in one or two types of tableware, just a little higher cost.
316 stainless steel insulation cup is harmless. 316 stainless steel is a kind of austenitic stainless steel, due to the addition of Mo element, so that its corrosion resistance, and high temperature strength has a greater increase in high temperature resistance can reach 1200-1300 degrees, so with 316 stainless steel insulation cup is harmless.
The most common materials used for insulation cups are 304 stainless steel and 316 stainless steel. Stainless steel is the most common type of steel, high temperature resistance of eight hundred degrees Celsius, with excellent stainless steel corrosion resistance and good resistance to intergranular corrosion performance. Good processing properties, high toughness, with a weak magnetic. 316 stainless steel due to the addition of molybdenum, so that its corrosion resistance, high temperature resistance are better, high temperature resistance can reach 1200-1300 degrees, can be used in harsh conditions, itself non-magnetic.
316 stainless steel has high corrosion resistance, can directly hold food and drink without being corroded, while 304 is easily corroded by the tea and coffee. 316 material in the carbon content is a little lower, good for health, 304 steel and 316 steel production process is also different, 316 steel in the pulling of the tube, the water up and other processes on the machine and the staff operating techniques have high requirements, so the production cost, 316 steel is the best choice. From the production cost, 316 steel is higher than 304 steel. From the stainless steel water cup selling price, the same brand with the same capacity of stainless steel cup 316 steel is about 20% more expensive than 304 steel.
316 material cup safety 3All metals can not guarantee 100% harmless, but compared to 304 stainless steel, which added the Mo element, so its corrosion resistance, high temperature resistance greatly improved, so its stability, to be better than the 304 stainless steel insulation cup, so the price of 316 stainless steel insulation cup to be higher.
1, stainless steel is made of iron-chromium alloy and then mixed with nickel, platinum, titanium and other metal elements, although many of these elements are essential trace elements, but if too much accumulation, it is not conducive to good health.
2, so the use of stainless steel insulation cup, to be used correctly, do not use to load soy sauce, salt, vinegar, etc., because of which the electrolytes will be electrolytic reaction with the stainless steel, resulting in harmful substances are dissolved.
3, even if our daily drinking water, because water is a weak electrolyte, so the electrolytic reaction will also occur, but generally weaker. After the stainless steel in the nickel, platinum, titanium and other metal elements will be ionized, and then absorbed by the body. So daily use, the use of insulation cups should be appropriate, if often used, it may lead to excessive intake of trace elements, which in turn leads to poisoning or disease.
