Some common sense questions about the thermos cup.

I don't know what material your thermos cup liner is, different materials should be removed in different ways, if it is a purple sand (or ceramic) liner, it is recommended to boil it in baking soda water, if it is stainless steel or glass liner, it is recommended to use toothpaste or hot vinegar to treat it.

Lemon is a hundred props, but milk is easy to penetrate, if lemon is useless, it is recommended to use cold water with a muslin to scrub, cold water to remove milk, blood stains smell more than hot water.

You can soak it in a little water with 84 disinfectant solution for a while, then clean it with a cup brush, and then rinse it with boiling water to remove it!

Soak the orange peel in boiling water and soak it a few times.

Try it with bamboo charcoal after drying.

I also have a lock cup for me. It's all coffee, and I've soaked it in salt water and it feels okay.

The principle is that the inner wall and the outer wall of the thermos cup are pumped into a vacuum, and the temperature of the inner wall is difficult to exchange with the outside world through conduction; The sealing cover prevents the entry of stupid air from the outside world, and avoids the heat exchange caused by the convection of the inside and outside air; The inner wall has a mirror coating or is made of highly reflective materials, which can reflect back the energy released by the outward radiation, preventing the loss of radiation energy and achieving the purpose of heat preservation. yards.

The function of the thermos cup is to prevent the heat exchange between the objects stored inside and the external environment, so the thermos cup can be used to keep heat and cold, but it cannot completely prevent the exchange of internal and external heat, and eventually the temperature inside and outside will tend to be equal.

The basic reason for the insulation of the thermos cup should be the material of the thermos cup. In general, the innermost layer of the thermos cup. All are stainless steel, 316 or 304.

Then the outer layer, there will be many layers of annihilation hall, like what kind of insulation layer, what kind of isolation layer, and what is the outermost layer? Anti-scald old bridge hand, anti-Shi Han is faintly making a better thermos cup, there may be. 56 floors.

That's because the insulation performance is not good enough, or there is a problem with the sealing performance of the thermos cup. For the thermal insulation of the thermos cup rental chain can mainly refer to the inner tank of the thermos cup, after filling with boiling water, tighten the cork or the lid of the thermos cup clockwise, after about 2 3 minutes, touch the outer surface and lower part of the cup body with your hands, if you find a warm feeling, it means that the thermal insulation performance is not good enough. Fill a glass of water, tighten the lid of the cup, invert it for a few minutes, and shake it a few times, if there is no leakage, it proves that its sealing performance is good.

Extended information: Use thermos cups "four do not install": 1. Thermos cups should not be loaded with acidic drinks Due to the high melting point, stainless steel will not release undesirable substances due to high temperature melting.

However, stainless steel is most afraid of strong acids, and if it is loaded with a strong acidic drink for a long time, it is likely to damage its inner tank. 2. The thermos cup should not be filled with milk The hot milk is packed in the thermos cup, so that the microorganisms in the milk will multiply rapidly at the appropriate temperature, resulting in spoilage.

There are many layers in the thermos cup, and its interlayer is generally vacuum to prevent heat conduction! It is then plated with silver so that the rest of the shed can be destroyed to block the heat radiation. Some cups have corks on the lid of the broken chain to prevent heat conduction.

The reason for the thermos cup to keep the base Qi temperature is mainly to solve the heat energy loss caused by thermal radiation and heat conduction, and the vacuum interlayer of the thermos cup effectively inhibits the occurrence of heat conduction. The inner layer of the thermos cup can reflect the color of the silver buried front and reflect the heat energy transmitted by the heat radiation bending.

The principle of thermos cup insulation is that vacuum can reduce heat conduction. The thermos cup is double-layered, and the interlayer in the middle of the layer is not in a vacuum state, and it is not easy to conduct the hot water or ice in the cup to achieve the effect of heat preservation or cold insulation.

The principle of thermos cup insulation is that the thermos cup is double-layered, and the interlayer is hollow, which makes use of the poor thermal conductivity of the air to prevent the heat from leaking out.

The thermos cup can keep warm because it isolates the air inside and the outside air, and cannot carry out heat exchange, so the thermos cup can keep warm.

Well, the principle of thermos cup insulation, in fact, is heat insulation, it is through the vacuum after the evacuation, Huai Na and then the air does not transfer heat, so he is not heat conductive.

In fact, the thermos cup is a double-layered, vacuum barrier, which can make the husband of the outside world not come, and the hot air inside can't get out. It is both rotten and cold, so its principle is very simple, if once the screen is not covered or then its thermal insulation effect does not exist.

Regardless of whether the bridge is heat or cold air conduction, a medium is required. The thermos flask section is double-layered, and the middle interlayer is vacuum-resistant, and the temperature is naturally not easy to disperse without conductive medium. In the same way, even if you use him to fill a popsicle, the cold air can't come out, and it won't melt easily.

The thermos cup is generally double-layered, and the inside is in a vacuum state, which can effectively block the transfer of heat. So the thermos cup can maintain the temperature for a long time.

The thermos cups are double-layered, and the interlayer is hollow, which makes use of the poor thermal conductivity of air to prevent heat leakage.

What is the principle of thermos cup insulation, and the principle of thermos cup insulation, that is. Convection. Reduced heat conduction. Closed. Convection.

Not only does the mug keep warm, but it also keeps the air cold cold because of the inner lining that prevents the temperature from slipping away.

The thermos cup makes the four kinds of tea drink of Xunming can not be loaded with 1It is not suitable for acidic drinks: stainless steel will not melt due to high temperature and release undesirable substances because of its high melting point.

However, stainless steel is most afraid of strong acid, and if it is filled with a relatively acidic drink for a long time, it may cause damage to the internal organs. 2.Not suitable for milk:

Some people put hot milk in a thermos cup, but this practice will allow the microorganisms in the milk to multiply rapidly in the right environment, causing diarrhea and abdominal pain. Because the acidic substances of milk in a high-temperature environment will cause a chemical reaction on the inner wall of the thermos cup, which will affect human health. 3.

Tea leaves contain a large amount of tannins, theophylline and a variety of vitamins, and are only suitable for brewing with water at about 80 degrees. The thermos flask will allow the tea to soak in high-temperature, constant-temperature water for a long time, just like decoction over a warm fire. Experts say that tea is not suitable for long-term soaking, because it may release heavy metal substances from the limbs, and the vitamins in the tea will also be destroyed.

4.It is not suitable to contain Chinese medicine: Some people also like to soak Chinese medicine in a thermos flask for easy carrying.

However, a large amount of acidic confession substances are dissolved in the boiled Chinese medicine, which is easy to react with the chemicals contained in the inner wall of the thermos flask, and dissolve into the decoction to have adverse effects on human health.

Summary. Hello dear, the first solution found by the teacher is that there is a handle on the side, and when the handle is lifted, the bottle body is tilted, and the cap sometimes falls off. A carrying handle should be added to it.

Second, the thermos flask at home is a glass liner that is easy to break. Stainless steel should be used instead. Third, the glass liner thermos flask, the liner is plated with a layer of silver, which is a waste.

It is best to use polished stainless steel instead. Fourth, the thermos flask is quite large and heavy. It is also dangerous for children to be unable to lift up the water.

A self-priming hose should be added, and the water will come out by pressing it. Fifth, the appearance design of the thermos flask is not good-looking, it should be designed to look good, and it is best to draw animations and mythological stories on it.

Hello dear, is there something wrong with your thermos cup?

School assignments. Thermos cup shortcomings, what can be done to solve them.

Hello dear, the first solution found by the teacher is that there is a handle on the side, and when the handle is lifted, the bottle body is tilted, and the cap sometimes falls off. A handle should be added to the side vertical. Second, the thermos flask at home is a glass liner that is easy to break.

Nowadays, many people will use thermos cups, which brings a great aspect to daily life. What are the precautions for the use of the thermos cup? PChouse will take you to find out.

The first thing to add when using a thermos cup is not too full, adding too much boiling water, it will overflow when the lid is screwed on, and there is a risk of scalding. Keep the mug out of the reach of children to avoid burns. Avoid burns when adding hot beverages, as the outside of the cup does not heat up when adding hot beverages due to heat insulation.

Avoid knocking, falling, colliding and strong impact, otherwise it will cause deformation of the cup body and reduce the heat preservation effect.

When cleaning, you can dilute 1-2 drops of edible vinegar in warm water, pour it into a thermos cup, open the lid of the cup and leave it for about 30 minutes, and wipe it clean with a soft rag. The use of vinegar is very effective in cleaning bacteria. Do not add the following substances to the vacuum cup:

1) Dry ice, carbonated drinks, etc. (increased internal pressure may cause the lid to fail to open or the liquid in the cup to spew out) 2) Salt or corrosive substances such as soy sauce and soup.

When not used for a long time, the inner tank should be kept dry sufficiently. To prevent odors or smudges, wash and dry well after use. Cleaning:

Add 1-2 drops of vinegar to the cup and soak for 30 minutes, then wash with a soft sponge or cloth to keep it clean.

Thermos cups have become a must-have in modern life, but there are also four taboos. First, it is strictly forbidden to place carbonated drinks. The carbon dioxide of carbonated drinks will react with the stainless steel material of the thermos cup to produce oxidized carbonate, which will not only affect the taste, but also enhance the harm to the human body.

Second, it is forbidden to pour boiling water directly. The overheated water temperature will cause the plastic material inside the thermos cup to melt, releasing harmful substances and reducing the insulation effect of the chain. Therefore, we should blow on the rim of the cup or pour it into another container before pouring the water to avoid burning the tongue.

Thirdly, the prohibition of arguments is to stop storing juice and tea for long periods of time. Fruit juice and tea are stored in the thermos cup for a long time, which will make the inner wall of the thermos cup in a humid state for a long time, which is easy to breed bacteria and bring harm to health.

Fourth, it cannot be inverted for a long time. Inverting for a long time can easily damage the sealing ring and cause water leakage. In addition, the thermos cup is inverted for a long time, which will produce peculiar smells and affect the drinking taste.

In short, the correct use of thermos cups can effectively reduce health risks, so when you use a protective canopy warm cup, don't ignore these four taboos.

The contraindications of thermos cups include the following:

1. Cleaning of thermos cups. When cleaning the newly bought thermos cup, it should be cleaned with neutral detergent and warm water before use, and never use alkaline detergent, alkaline detergent will have a bad impact on the cup, which will affect the service life of the thermos cup.

2. Twist the lid of the cup. Don't use too much force when twisting the lid of the cup, as long as you tighten it, ensure that there will be no water leakage, and using it too violently may cause the screw mouth of the cup to fail, which will affect the normal carrying of the user.

3. Add water. If the heating water in the thermos cup is not suitable for adding too much water, not only will there be the risk of overflow scalding, if the upper cover of the thermos cup is plastic, if the plastic is exposed for a long time, it is easy to cause deformation, or the molecular structure changes, which is not conducive to the health of the body.

4. Do not add dry ice and carbonated drinks and other liquids that are easy to produce high pressure in the thermos cup, and it is best not to add liquids that are easy to deteriorate such as juice and milk.

5. When the thermos cup is not in use, remember to pay attention to the preservation of the thermos cup to avoid the deformation of the cup body and plastic decoration caused by dropping, collision and strong impact, so as not to affect the thermal insulation effect. If you don't use it for a long time, it's best to pour out the water from the cup and dry it.
