Focus on high-quality water bottle for 15 years

Copper Plating On The Inner Liner Can Enhance The Thermal Insulation Effect Of The Thermos Flask

In general, the thermos flask we see is generally made of ceramic or stainless steel and vacuum, which makes the water bottle have a tight seal. In addition, the vacuum insulation layer can delay the heat dissipation, so as to better heat preservation.

In general, the thermal transmission of the thermos flask includes radiation, convection and transmission. The bottle body adopts double-layer stainless steel structure, and the vacuum structure between the bottle body and the bottle body can avoid heat loss.

Generally, the inner liner of the thermos flask is silvered inside, which can form an effective heat insulation net inside the water bottle. Now on the market, gradually launched a high-quality inner wall copper-plated thermos flask, its insulation effect is about 30% better than the ordinary water bottle of the same type.

Theoretically, the performance of copper plating on the inner liner is stable and corrosion resistance is strong. It is the same heat preservation principle as the traditional silver plating. The heat radiation of the inner wall will be blocked by copper plating and reflected back, effectively reducing heat loss, greatly enhancing the effect of heat preservation and cold insulation.

Therefore, most of the thermos flasks now adopt the copper plating technology of the inner liner, which makes the heat preservation effect of the thermos flask better. In addition, the sealing performance of the thermos flask also plays an important role in the insulation effect. The better the sealing is, the more difficult the heat will be lost, and the better the insulation effect will be.
