1. What do you think of the authenticity of Xiangyin children's thermos cup?
1, simple capacity discrimination method
The depth of the tank is basically the same as the height of the shell, and the capacity (difference 16- 18mm) is in line with the nominal value. In order to cut corners and make up for the lack of material weight, some domestic brands add sand and cement blocks to cups, and heavier cups are not necessarily good.
2. Simple identification method of stainless steel materials
There are many specifications of stainless steel materials, among which 18/8 means that this stainless steel material contains 18% chromium and 8% nickel. The materials that meet this standard are green products that meet the national food-grade standards, and the products are rust-proof and corrosion-resistant. Ordinary stainless steel cups are pale or dark in color. After soaking in salt water with the concentration of 1% for 24 hours, rust spots will occur, and some elements contained in them exceed the standard, which directly harms human health.
3. Simple identification method of thermal insulation performance
Pour boiling water into the thermos cup, tighten the cork or lid clockwise for 2-3 minutes, and then touch the surface of the cup with your hands. If the cup is obviously warm, especially if the lower part of the cup is heated, it means that the product has lost its vacuum degree and cannot achieve good insulation effect. Some people will use their ears to determine its thermal insulation performance, which is wrong. The ears can't hear whether it is a vacuum.
4, sealing performance discrimination method
After the thermos cup is filled with water, tighten the bottle stopper or cup cover clockwise, and put the thermos cup flat on the desktop, where there should be no water seepage; The screwing-in and screwing-out of the cup cover and the cup mouth should be flexible without gap. Fill a glass of water for four or five minutes, or shake it a few times to verify whether there is water leakage.
5, cup appearance identification method
See whether the surface polishing of the inner container and outer container of the thermos cup is uniform, whether there are scratches and abrasions, and whether the welding of the mouth of the thermos cup is smooth and consistent, which is related to the comfort when drinking water, whether the internal seal of the thermos cup is tight, whether the plug is matched with the cup body, and whether the mouth of the thermos cup is as round as possible.
6, check the cup label and other accessories.
See if the thermos cup is marked with product name, capacity, caliber, manufacturer's name and address, adopted standard number, usage and precautions. Japan is a country that attaches importance to quality, and will clearly indicate the performance of products in strict accordance with the requirements of relevant standards.

The principle of heat preservation is the same as that of thermos bottles, except that people make bottles into cups for convenience. There are three ways to spread heat: radiation, convection and transmission. The silver liner in the thermos cup can reflect the radiation of hot water, and the vacuum between the liner and the cup can block the heat transfer, while the bottle which is not easy to transfer heat can prevent the heat convection. The hot water bottle also applies the principle of magnetized water, that is, magnets are added to the bottom and cap of the bottle to magnetize water.
