How to Choose the Right Thermos Water Bottle for You?
What factors determine the effect of insulation?
The principle of insulation is very simple. Generally speaking, there is a vacuum layer sandwiching between two layers of stainless steel. The insulation cup relies on this vacuum layer to isolate the air and the liquid inside the insulation cup, playing the role of heat preservation.
There are many factors that affect the insulation effect of the vacuum flask. For example, a narrow-caliber thermos cup has a slightly better effect than a wide-mouth thermos cup, because a narrow-caliber thermos cup has a smaller heat dissipation area, so the insulation effect is relatively better.
At present, stainless steel is the main material used in the vacuum flask market. Heavy metal materials such as nickel and chromium are added to stainless steel. Generally speaking, the high-quality and high-priced thermos cups produced by qualified regular manufacturers are all made of standard food-grade stainless steel, which is what we often call 304 stainless steel.
The stainless steel has the advantages of high strength, stable performance, strong acid and alkali resistance, and the product is harmless to the human body. Even in pursuit of durability and safety, some manufacturers use medical grade stainless steel, which is 316 stainless steel.
The high temperature resistance of the stainless steel can reach 1300 degrees Celsius, and it can be used under harsh conditions, and there is basically no phenomenon of thermal expansion and contraction.
The prices of vacuum flasks on the market vary greatly. How should we choose the thermos cup that suits us? The prices of vacuum flasks on the market vary greatly. How should we choose the thermos cup that suits us?
Pay attention to the packaging information of the product when buying. Generally speaking, there will be material signs on the packaging or the cup. The vacuum flask made of 304 stainless steel or 316 stainless steel is a good choice.
Secondly, choose products with relatively good insulation effect. Consumers can refer to the factors that affect the insulation effect and choose a suitable insulation cup according to the capacity, cup diameter and cup lid. Consumers do not need to blindly pursue large capacity. Generally speaking, 350ml-500ml is sufficient for office use. You can choose mugs, suction, coffee cups and other thermos mugs with handles. If you have children at home and need to go out frequently, you can equip a children's cup, which not only has an auxiliary handle, but is also convenient for drinking.
The mugs, suction mug, coffee cups and children's cups produced by Dongguan Zhanyi Commodity Technology Co., Ltd. are all made of food-grade or higher standards than food-grade stainless steel. We have passed ISO9001 quality system certification, Starbucks factory inspection, Nestlé factory inspection, BMW factory inspection, and Huawei factory inspection.
The products are exported to Europe, America, Japan and South Korea all year round to ensure that every water cup can pass the dishwasher test.
