The insulation cup is very practical in the cold season, it uses a vacuum layer design, the vacuum thermos cup can make the internal water delay to slow heat, the holding time is longer. In addition to the insulation cup design, the insulation of the insulation cup is also related to its material. So what is the material of the thermal insulation cup?
In the current cup of pot market, the inner liner is mainly glass, magnetization, stainless steel, ceramics, etc., which have advantages and disadvantages. Let's introduce the type of material that is common in the common cup and analyzes what thermal insulation cup is best.
Ceramic Insulation Cup
The ceramic thermal insulation cup is in the cooling cup. This product is not very common. With the development of cheap plastic cups and metal cups, the number of people who use ceramic cups still decreases, but ceramic cups and plastic cups and metal cups It is the most healthy comparison.
1. The ceramic cup has less harmful gases and materials from the plastic cup compared to the plastic cup. According to experts, they have confirmed the possibility of using plastic cups for a long time.
2, the ceramic cup is completely harmless, it does not use the possibility of intake of harmful metals as long as metal cups.
3. Due to the presence of ceramic cups, the iron water does not directly contact the carbon brick, and the iron water and alkaline substances are mitigated from the structural design, and the alkaline substances are destroyed, erosion, and brushing, etc. They are high-grade ceramic materials with low thermal conductivity, high anti-inridity, and impact resistance. Eliminate the embrittlement layer of large blocks.
4, increase the temperature of the iron water, reduce the heat loss: the ceramic cup is made of a material having a low thermal conductivity than carbon bricks, and thereby reducing thermal disappearance through the furnace bottom and furnace. Correspondingly, the iron water can maintain a high temperature and create good energy-saving conditions for the production converter production.
5, easy to ventilation operation: Due to the thermal insulation of the ceramic cup, during the blast furnace is reduced, the heat loss is reduced, which is conducive to the normal operation.
6, to prevent iron water leakage: Since the equation of the iron water roller is close to the inner surface of the furnace lining, it has caused the brick to shrink due to the swelling of the refractory, so that the brick is reduced. Permeation is limited so that the risk of burning in the furnace is minimized.
Stainless Steel Insulation Cup
Really qualified, stainless steel that does not have any adverse effects on the human body should be that the food-grade 304 stainless steel, the national standards are also clearly pointed out. Because iron elements are contained in stainless steel, we need trace elements that we need to take care of them. Stainless steel cups belong to alloy metal products, depending on the use, the metal elements of this cup will be different, and common metal elements include iron, silicon, Carbon, aluminum, etc. These elements are unable to provide us with other cups. It not only keeps insulation but also cools, it is also very convenient to use in daily life.
The disadvantage of stainless steel insulation cups is: stainless steel mugs should not be used for tea and coffee. Because the tea is soaked in the warm water in the thermal mold, it is like a gently fried egg, and the tea polyphenols contained in the tea will leak a lot of milk, which is a strong color of the tea, with a bitter taste. Also, since the water in the thermal cup will maintain a high water temperature, the aroma oil in the tea will volatilize, and it also reduces the fragrance of tea. The most serious point is that nutrients such as vitamin C contained in tea will be destroyed when the water temperature exceeds 80 ° C, and the healthy function of the tea should be lost.
In addition, since stainless steel is a metal composition, the substance is more active, and some impurities will occur during the production process, and how much impurities will harm the human body. In addition, there is still a short-quality stainless steel thermal insulation cup in the market, so that the mug can not guarantee whether it is equally safe.
Glass Insulation Cup
Glass insulation cup, healthy but does not prevent fall. The reason why the glass insulation cup is safer is because the glass is sintered by the inorganic silicate, which is a very stable substance, which is the incompatibility impurities contained in the production process and will not disclose it. And the glass is easily cleaned, so it is the most secure with a glass. However, glass tea has the disadvantage of breaking, so it is inconvenient to carry with you.
Purple Ssert Mold
The purple sand insulation cup not only has the basic functions of stainless steel insulation cups, but also tea, health, conditioning efficacy, and self-use drinking tea or when high-grade gifts give friends and family are very good choices.
The purple sand insulation cup produced by the regular manufacturer, the liner is generally developed by authentic pure natural purple campus, and the outer shell is usually the anti-fall, anti-stainless steel material. The purple sand insulation cup is different from the stainless steel mug. The purple sand insulation cup can be used to make tea, and the cup can absorb the tea juice. After a period of use, it can increase "tea rust", so that the boiling water is injecting the boiling water There are also tea. In addition, the cold and hot and cold in the purple sand insulation cup is strong, regardless of the cold winter month or in the summer, after injection of boiling water, it will not cause flooding due to the temperature of the temperature, and the heat of the sand is slow, and it is not hot.
The purple sand mug is the same as the teapot, which is used to make the tea flavor. It is other of the other tea sets, even if it is cool, it can still be kept. If you use a purple sand insulation cup for a long time, the purple sand cup not only does not abrasive and scratches. In the contrary, because it absorbs the tea oil in the tea soup, it will be light like jade, which makes people love it. A variety of minerals and trace elements in the purple coats have a health care effect on the human body. The purple sand cup is practical, elegant, integrated with practical and decoration, is the elegant gift of the gift, and it is worthy of the permanent collection.
Plastic Insulation Cup
Usually, the plastic thermos cups on the market can only have thermal insulation. Its thermal insulation can only be 2 to 3 hours, the lower the room temperature, the faster the heat loss. The plastic thermos cup can also be insulated, but the thermal insulation time of the plastic cup is far from the stainless steel, the ceramic thermal insulation cup is far away, and it is not suitable for the autumn and winter season.
Contrast summary:
Stainless steel thermal insulation cups are now the best choice, although the ceramics are highly safe and excluding hazardous substances, the market is less common; Ziha has warm winter and summer cool, multi-function, but authentic pure natural purple coat less It is also very difficult to see; the glass is high, but it is not possible to carry it, fragile; plastic thermos cups have a suspicion of carcinogenic substances, heat preservation, and time is also very poor, need to buy it carefully.
