To make a good insulation cup, one is to be non-toxic, but to have a good insulation effect. If you do n’t know how to choose a thermos cup, it is difficult to choose a quality thermos cup at one time when you buy it. Therefore, you need to learn something about purchasing a high quality thermos cup for children.

First, it is better to choose the inner and outer double layers of stainless steel. The performance of the vacuum layer is better and lasting. The heavier weight will be better, and some light weights are unqualified. In addition, if the thickness of the inner and outer steel is too thin, such as a 500 ml bullet-shaped insulation cup, the thickness is only about 0.3, which will greatly affect the degree of vacuum during production, and thus affect the vacuum insulation performance of the insulation cup from cold and heat. The life of the cup will also be shortened. Baby's insulation cup, the outer paint must try to choose the health and safety guaranteed.

Second, pour boiling water into the thermos cup and tighten the stopper or cap clockwise for 2-3 minutes, then touch the outer surface of the cup with your hand. If the cup has obvious warming phenomenon, it means that the product has lost the vacuum degree and cannot reach Good insulation effect.

Third, fill a glass of water, screw the lid tightly, and invert for a few minutes, or shake it a few times with force. If there is no leakage, it proves that its sealing performance is good. Fill a cup of water, screw the lid tightly, invert for a few minutes, or shake it a few times with force. If there is no leakage, it proves that it has good sealing performance.

Fourth, it is very important whether the plastic parts of the insulation cup are healthy and environmentally friendly. It can be identified by smell. If the thermos cup is made of food-grade plastic, its odor will be small, the surface will be bright, no burrs, long life and not easy to age. Ordinary plastics or recycled plastics are characterized by high odor, dark color, many burrs, and plastics are easy to age and break.

For stainless steel insulation cups, the quality of stainless steel is very important. There are many specifications for stainless steel materials, of which 18/8 means that the stainless steel material contains 18% chromium and 8% nickel. Only materials that meet this standard are stainless steel materials that meet the specifications and are green products.

Fifth, the depth of the liner is basically the same as the height of the shell, (the difference is 16-18MM) The capacity is consistent with the nominal value. Some inferior insulation cups add sand and cement blocks to the cup to make up for the missing weight. Misunderstanding: The heavier the cup (pot) is, the better. The depth of the bladder is basically the same as the height of the shell, (the difference is 16-18MM) The capacity is consistent with the nominal value. Some inferior insulation cups add sand and cement blocks to the cup to make up for the missing weight. Misunderstanding: The heavier the cup (pot) is, the better.

6. Inferior stainless steel insulation cups not only cannot be insulated and leak-proof, but also cause diseases. In order to avoid damage to consumers' health, please do not buy particularly cheap stainless steel insulation cups. Stainless steel insulation cup is also called stainless steel vacuum insulation cup. It is made of non-toxic high-quality stainless steel plate through punching and drawing and vacuum sealing. It keeps the water temperature above 50 degrees within 5 hours. Popular with consumers. Low-quality stainless steel insulation cups not only cannot be insulated and leak-proof, but also cause diseases. In order to avoid damage to consumers' health, please do not buy low-quality stainless steel insulation cups that are particularly cheap. Stainless steel insulation cup is also called stainless steel vacuum insulation cup. It is made of non-toxic high-quality stainless steel plate through punching and drawing and vacuum sealing. It keeps the water temperature above 50 degrees within 5 hours. Popular with consumers.
