Why doesn t the thermos cup keep warm after removing limescale with vinegar 30

1. The thermos cup hurts the inner tank after removing scale with vinegar, so the thermos cup cannot be kept warm;

2. The thermos cup is generally a container for water made of ceramic or stainless steel and a vacuum layer, with a lid on the top and a tight seal, and the vacuum insulation layer can delay the heat dissipation of liquids such as water installed inside, so as to achieve the purpose of heat preservation;

3. The thermos cup is developed from the thermos flask, and the insulation principle is the same as the thermos flask, but people make the bottle into a cup for convenience.

The thermos cup can be soaked in vinegar to remove scale, and the thermos cup is not kept warm and has nothing to do with whether or not to use vinegar.

Reasons why the thermos cup is not kept warm:

1. Being hit or injured by a heavy blow, etc.

After the thermos cup is hit hard, there may be a rupture between the shell and the vacuum layer, and the air enters the interlayer after the rupture, so the thermal insulation performance of the thermos cup is destroyed. This is normal, no matter what kind of cup, they have the same principle, that is, use double-layer stainless steel to pump out the middle air to reach a certain vacuum.

Let the heat of the water inside spread out as slowly as possible.

This process is related to the process and the vacuum level of pumping. The quality of the process is the length of time that determines the poor heat retention of you. In addition, in the process of convenient use, your thermos cup will become insulated if it is heavily damaged and bruised, because the vacuum layer leaks air into the interlayer, forming a convection in the interlayer, and it will not achieve the effect of isolating the inside and outside.

In the process of use, it is necessary to avoid collision and impact, so as not to damage the cup or plastic, resulting in insulation failure or water leakage. When tightening the screw plug, the force should be appropriate, and do not rotate too much, so as to avoid the failure of the screw buckle.

2. Poor sealing.

Check if there is a gap in the cap or other places, if the lid is not tightly closed, it will also cause the water in the thermos cup to be lukewarm soon. The common vacuum cup on the market is generally a container for water made of stainless steel and a vacuum layer, with a lid on the top and a tight seal, and the vacuum insulation layer can delay the heat dissipation of liquids such as water installed inside, so as to achieve the purpose of heat preservation.

The falling off of the sealing pad and the failure of the cup lid to close the lid will make the sealing performance poor, thus affecting the thermal insulation performance.

3. The cup is leaking.

It is also possible that there is a problem with the material of the cup itself, and some thermos cup processes are defective, and there may be a pinhole-sized hole on the inner tank, which accelerates the heat transfer between the walls of the two cups, so that the heat is quickly lost.

4. The sandwich of the thermos cup is filled with sand.

Some businesses in order to shoddy means of manufacturing thermos cups, such thermos cups are still very warm when they are bought, but after a long time, the sand may reflect with the inner tank, resulting in rust of the thermos cup, and the thermal insulation effect is very poor.

5. It's not a real thermos cup.

A cup with no buzzing sound in the mezzanine is not a thermos cup. Put the thermos cup in your ear, and you can't hear the buzzing sound inside the thermos cup, which means that the cup is not a thermos cup at all, and such a cup will definitely not keep warm.

When you remove limescale, it is estimated that you will hurt the inner tank, and of course the inner tank will not be kept warm if the inner tank is incomplete. There is also a lid that is not tight, as well as can not be insulated.

Because vinegar is very corrosive, when washing the cup, your vinegar has been corroded when washing the cup, so your thermos cup can no longer be used, and it is no longer insulated.

Metal thermos cups are usually double-layer vacuum process insulation, vinegar is a weakly acidic liquid, corrosive to metal, some thinner or poor performance of inferior stainless steel (non-304 and other food-grade high-quality stainless steel) liner will be corroded out of the trachoma that is not easy to see with the naked eye, resulting in vacuum leakage without insulation.

It is possible that the insulation of the cup has been destroyed by the dissolution of vinegar.

Hello, it is generally considered that the thermos cup may be used for a long time, so it will not be insulated, or the thermos cup is broken.

Not keeping warm has nothing to do with removing limescale with vinegar.
