Why the thinner the wall thickness of the thermos cup, the better the insulation effect?

Beginning in 2017, lightweight cups began to appear in the water cup market, and it didn't take long for ultra-lightweight cups to appear in the market.What is a lightweight cup?

What is a super lightweight cup?

Taking a 500ml stainless steel thermos cup as an example, the net weight produced according to the traditional process is between 220g and 240g.With the same structure and the same lid, the weight of the lightweight cup is about 170g--150g, and the weight of the ultra-lightweight cup will be between 100g--120g.

How are lightweight cups and ultra-lightweight cups made?At present, the process adopted by each company is basically the same, that is to say, the cup body with normal gram weight according to the traditional process is reprocessed by the spinning process.Depending on the product structure, different spinning thicknesses can be achieved.After removing the material that was cut out within the scope of the process, the existing cup body will naturally become lighter.

Well, the editor made another popularization of the lightweight cup in the front, and now it is to answer the question of why the thinner the wall thickness of the thermos cup, the better the thermal insulation effect.

The editor mentioned in many previous articles what is the process of thermal insulation cups.So since the heat preservation is achieved through the vacuum process, how can it be related to the thickness of the cup wall?

In the case of using the same production process and the same technical parameters of vacuuming, the wall thickness of the thermos cup will conduct relatively faster heat.Thicker-walled materials have a larger volume of heat-absorbing contact, which in turn dissipates heat faster.The volume of heat-absorbing contact with the thin wall of the thermos cup will be relatively small, so the heat dissipation will be slower.

But this problem is relative. It cannot be said that the thin wall of the thermos cup must be very warm.The quality of the thermal insulation effect depends more on the quality of the production technology and the specification of the production process management.At the same time, not all water cups are suitable for the spinning process.There are also products with a larger capacity, such as a 1.5-liter thermal pot, even if its structure meets the production of the spinning process, it is not recommended to use the spinning technology.The thinning of the wall thickness by the spin-thinning process also needs to be within a reasonable range.

If the wall thickness is too thin, the tensile force that can be endured is lower than the suction force generated by vacuuming, then the slight result is that the cup wall is deformed, and the serious result is that the inner wall and the outer wall will collide, so that the effect of heat preservation will not be achieved.The suction generated by the vacuuming of a large-capacity thermos cup or thermos cup is greater than that of a small-capacity water cup.The wall that can achieve stability after the small-capacity water cup is thinned will be deformed on the large-capacity water bottle.
