The mold tooling workshop has advanced CNC lathes, milling machines, CNC wire cutting machine tools and other equipment. Able to independently develop various stainless steel vacuum cups.
What is a vacuum insulated cup?
A vacuum thermos cup is generally a water container made of stainless steel with a vacuum layer. It has a lid on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of water and other liquids contained inside to achieve heat preservation. purpose.
The thermos cup is developed from the thermos bottle. The insulation principle is the same as that of the thermos bottle, but people make the bottle into a cup for convenience. There are three ways to spread heat: radiation, convection and transfer. The silver bladder inside the thermos cup can reflect the radiation of hot water. The vacuum between the bladder and the cup body can block the transfer of heat. Bottles that are not easy to transfer heat can prevent heat convection.
Tips for purchasing thermos cups
1. Use magnets: Take two thermos cups - one attracts magnets and the other does not absorb magnets. There is enough space in the two thermos cups. The water is about 80 degrees Celsius, and the lid of the cup is tightly closed. After three hours, the water temperature of the thermos cup with the magnet changed to 40 degrees, while the water temperature of the thermos cup without the magnet was still above 70 degrees. From such an experiment, it can be seen that the effect of magnet-attracting thermos cups is not strong
2. Use boiling water: After filling with boiling water, tighten the bottle stopper or thermos cup lid clockwise. After about 2 to 3 minutes, touch the surface and lower part of the cup body with your hands. If you find a warm feeling, it means that the heat preservation performance of the thermos cup is not good enough.
3. Use accessories: It is very important whether the plastic accessories of the thermos cup are healthy and environmentally friendly. You can identify it by smelling it. If the thermos cup is made of food-grade plastic, it will have less smell, bright surface, no burrs, long service life and not easy to age; if it is made of ordinary plastic, it will be inferior to food-grade plastic in all aspects. plastic.
