Be wary of cut corners and shoddy water bottles in the market!(Three)
The editor continues, and today I will continue to give examples of which products are cut corners and shoddy water glasses.
Type D water cup is a general term, referring to those high borosilicate glass water cups that are advertised and sold on e-commerce platforms.How to cut corners for glass water cups? When selling glass thermos cups on e-commerce platforms on the Internet, one of the main promotions of all merchants is high borosilicate. High borosilicate glass has extremely high impact resistance and temperature difference resistance. When the high borosilicate glass water cup made of excellent materials is used for the drop test, it falls freely from a height of 70 cm in the air, and the water cup will not break after landing.
At the same time, pour boiling water into the water cup immediately after pouring out -10°C ice water, and the water cup will not burst due to the huge temperature difference.However, the high borosilicate glass water cups sold by many businesses are not made of high borosilicate, but medium borosilicate material. Although it has a certain resistance to temperature difference, it cannot reach the standard of high borosilicate. The price difference between the two materials is large, but the appearance of the finished product is similar, and it is difficult for consumers to distinguish.
The E-type water cup, this example also refers generally, and this type of water cup generally has the problem of overpromoting and false propaganda.For example, most stainless steel thermos cups sold on e-commerce platforms will write about the copper plating process on the inner wall when promoting them, and use this to emphasize the thermal insulation performance of the water cup. But in fact, about 70% of the stainless steel thermos cups currently on the market do not have a copper plating process on the inner wall of the water cup. In fact, the influence of copper plating on the thermal insulation effect of the water cup is almost imperceptible in a short period of time. The editor has done rigorous tests, and the difference between the copper-plated and non-copper-plated water cups of the same style and capacity is almost the same within 6 hours.
After 12 hours, the difference is about 2°C, and after 24 hours, the difference is about 3°C-4°C, but this is hardly noticeable to ordinary consumers. The water cup with copper plating inside the same water cup is compared with the water cup without copper plating for life experiment. After 3 months, the insulation decay rate of the former is almost zero, while that of the latter reaches 2%; After 6 months, the insulation decay rate of the former is 1%, and that of the latter is 6%; After 12 months, the insulation decay rate of the former is 2.5%, and that of the latter is 18%.The meaning of 18% is an example. If the insulation time of a new water cup is 10 hours, the insulation time will be reduced to 8.2 hours after 12 months of use.
Examples of over-promotion abound. Some water cups emphasize that long-term use can improve body functions, which has no scientific basis, and most of such water cups have hardly been scientifically tested, but the developers take it for granted and at the same time it is to increase gimmicks. In short, friends, when buying water glasses, don't be too superstitious about water glasses with many functions and powerful promotion. Even if you like this kind of water cup very much, it is recommended that you try to check whether the water cup has a sound test report when purchasing.
