1. Thermal insulation effect
The frosted inner wall and mirror surface of the thermos have little effect on insulation. The core of insulation is double-layer vacuum, not the smoothness of the inner wall. The difference between frosted and mirrored surfaces has almost no effect on the insulation time. Of course, if there are obvious quality problems such as unevenness and burrs on the inner wall of the insulated cup, it will affect the insulation effect.
2. Difficulty level of cleaning
The inner wall surface of frosted thermos cups is often rough with a texture similar to “sandpaper”, which provides some assistance for cleaning and is relatively easy to clean. Однако, if a thermos cup has been used to hold brightly colored and precipitated beverages such as milk, сок, кофе, и т. д., the pigments on the inner wall of the frosted cup are not easy to clean and will leave traces. The inner wall of the mirror insulated cup is smooth and flat, and special oxidation treatment is used to prevent scale and pigment precipitation, making it relatively easy to clean.
3. Health and Safety
The material of the inner wall of the thermos determines the safety and health novelty of its use. В настоящий момент, the inner wall material of insulated cups on the market is mostly stainless steel. Some frosted insulated cups have relatively rough inner wall surfaces, which are prone to residual bacteria and harmful substances, and are difficult to clean thoroughly. Кроме того, frosted treatment can also damage the stainless steel surface of the cup, thereby affecting the safety of use. The inner wall surface of the insulated cup treated with mirror technology is smooth and flat, with relatively less residual harmful substances, and is easy to disinfect and clean, making it healthier and safer.
In summary, the frosted and mirrored inner walls of insulated cups have their own advantages and disadvantages, and consumers should choose according to their preferences and needs. If you need to store drinks with obvious sediment or if cleaning and hygiene are relatively easy, you can choose to use insulated cups treated with mirror technology; If you pay attention to the feel when choosing a thermos, the frosted texture will give a warm and comfortable feeling, and you can choose a thermos with a frosted inner wall. Regardless of which type of thermos cup to choose, it is still important to understand the material and inner and outer walls of the thermos cup, keep it clean, and use it healthily.
