The vacuum insulation cup<\/a> Jika ia plastik biasa, ia akan lebih rendah daripada plastik gred makanan dalam semua aspek.<\/p>\n

The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside to achieve the purpose of heat preservation.<\/p>\n

Gunakan magnet:<\/strong> take two insulation cups, one attracts magnets, and the other does not attract magnets.<\/p>\n

Both thermos cups are filled with water at about 80 degrees, and the lid is tightly closed.<\/p>\n

After three hours, the water temperature of the thermos cup that attracts the magnet becomes 40 degrees, while the thermos cup that does not attract the magnet is still more than 70 degrees.From such an experiment, we can see that the insulation effect of the insulation cup that attracts magnets is not strong.<\/p>\n

Gunakan air mendidih:<\/strong> After filling the bottle with boiling water, tighten the bottle stopper or the cover of the thermos cup clockwise.<\/p>\n

After about 2-3 minutes, touch the outer surface and lower part of the cup.<\/p>\n

If you find warm feeling, it means that the insulation cup\u2019s thermal insulation performance is not good enough.<\/p>\n

It can also test the tightness of the insulation cup.<\/p>\n

Fill a glass of water, tighten the cup cover, turn it upside down for a few minutes, or shake it vigorously.<\/p>\n

If there is no leakage, it is proved that its sealing performance is good.<\/p>\n

Gunakan aksesori:<\/strong> whether the accessories used are healthy.<\/p>\n

Whether the plastic parts of the thermos cup are healthy is very important.<\/p>\n

It can be identified by smell. If the insulation cup is made of food-grade plastic, its smell will be small, its surface will be bright, burr-free, its service life will be long and it is not easy to age;<\/p>\n

If it is ordinary plastic, it will be inferior to food-grade plastic in all aspects.<\/p>","protected":false},"excerpt":{"rendered":"
