What's the difference between vacuum cup and ordinary cup? Next, Wubairun Mall will share it~
1. Different materials
Customized insulation cup There are many kinds of materials for ordinary insulation cups, including ceramic, stainless steel, plastic, purple sand and glass. The vacuum insulation cup is just a cup body made of stainless steel and vacuum layer. The vacuum insulation layer can delay the heat dissipation of water and other liquids inside to achieve the purpose of insulation.
2. Different price points
The ordinary thermos cups sold in the general market only have the effect of thermal insulation. After hot water is injected, the thermal insulation is usually about two to three hours. The price of this ordinary thermos cup is far from the price of vacuum thermos cups. When you buy it, you should carefully identify the manufacturers of thermos cups and do not buy them on the street casually, The safety and thermal insulation performance of this cheaper cup cannot be guaranteed.
3. Different thermal insulation performance
Customized insulation cup The vacuum insulation cup has the characteristics of cold and heat preservation. The vacuum cup with high vacuum rate can achieve the heat preservation effect of 10 hours. However, ordinary thermal insulation cups have lower thermal insulation performance, stronger heat dissipation than vacuum cups, and the thermal insulation performance can usually reach less than two to three hours.
4. Different touch feeling
Pour boiling water into the cup in one minute, and then make a difference by touching the outer body of the cup. The hot cup is not a vacuum insulated cup, but a simple ordinary insulated cup. If it is not hot, it is a vacuum insulated cup. The vacuum insulated cup can keep warm for more than 6 hours, and the vacuum insulated cup with a high vacuum rate can keep warm for about 10 hours.
5. Different working principles
The thermos cup is developed from the thermos bottle. The principle of heat preservation is the same as that of thermos bottle, but people make the bottle into a cup for convenience. The silver cup liner in the insulation cup can reflect the radiation of hot water, the vacuum of the cup liner and the cup body can block the heat transfer, and the bottle that is not easy to transfer heat can prevent thermal convection.
Customized insulation cup The vacuum insulation cup is generally a water container made of stainless steel and vacuum layer, which is made of double stainless steel inside and outside. The tank and shell are combined by welding technology, and the air in the interlayer between the tank and shell is pumped out by vacuum technology to achieve the effect of vacuum insulation
