Is the Principle of Thermal Bottle and Keep Cold Bottle the Same?
When choosing water bottle, many people may have doubts about heat preservation and cold preservation. Are these two properties common? There are thermal bottles for heat preservation and cold bottles for cold preservation. Next, Dongguan Zhanyi Commodity Technology Co., Ltd. will answer for everyone.
In fact, the thermos bottle and the keep cold bottle are actually universal. The thermos bottle we usually say has both the heat preservation effect and the cold preservation effect.
The thermal insulation principle of a thermos is not complicated. The main reason is its vacuum layer. Vacuum the body of the thermos bottle to form a vacuum layer. As we all know, vacuum does not conduct heat, so the heat will always remain at the original temperature, and the heat release will be very slow. Some thermos manufacturers will plate copper or silver on the inner tank of the thermos to reflect the heat to achieve the purpose of heat preservation. The more heat in the thermos cup, the longer its holding time, so the heat preservation effect of the large-capacity narrow-mouth thermos kettle will be better.
The thermos is usually made of 304 or 316 stainless steel. 304 has high temperature resistance and excellent corrosion resistance. It is usually widely used in medical equipment and food utensils. Therefore, as a material for thermos bottles, it has little harm to the human body.
Compared with 304 stainless steel, the material of 316 stainless steel thermos is better, and the corrosion resistance and high temperature strength are particularly good. Even under very harsh conditions, the use effect will be very good. 316 material has higher strength than 304 material and has a longer service life.
Usually ice cubes may be put in, and it will be designed into a wide-mouth bottle according to the purpose of cold preservation.
The cap is more suitable for drinking directly. There is no problem with holding hot water, but because of its wide-mouthed cup design, heat dissipation is faster than a narrow-mouthed cup, so the heat preservation effect will be weaker than that of a small-mouth thermos cup.
The double-layer stainless steel vacuum thermos produced by Dongguan Zhanyi Commodity Technology Co., Ltd. insists on using food-grade 304 stainless steel or medical-grade 316 stainless steel in material. The heat preservation time can reach 18 hours, and the cold preservation time can last up to 24 hours.
