If you want to buy a thermos cup, you will find that there are a wide range of products on the market, ranging from tens to hundreds or even thousands of yuan. Does such a large price difference mean that the effect of thermos cups is also different? Insulation cup manufacturer Tell consumers how to choose the right product? Experts remind that the price of insulated cups is too high or the brand effect. You should pay attention to the material, capacity and other information when purchasing insulated cups.
Many factors affect the insulation effect
What factors determine the insulation effect? Huang Dapeng, manager of the Lekou and Lekou Product Training Department, explained that the heat preservation principle of the heat preservation cup is very simple. Generally speaking, there is a vacuum layer sandwiched between two layers of stainless steel. The heat preservation cup relies on this vacuum layer to isolate the air and the liquid in the heat preservation cup, playing the role of heat preservation.
Huang Dapeng said that there are many factors that affect the thermal insulation effect of the cup. For example, the thermal insulation effect of the cup with large capacity is slightly better, because the more water, the more total heat. In the same time, the larger the capacity, the slower the heat dissipation; The insulation cup with narrow diameter is slightly better than that with wide mouth. Because the heat dissipation area of the insulation cup with narrow diameter is smaller, the insulation effect is relatively good; The insulation effect of single-layer cover is not as good as that of multi-layer cover. If there is a bouncing cover inside, add a thermal insulation cup similar to the cup cover, and its thermal insulation effect is better than the common office cup with a single cover; In addition, different manufacturers have different designs for other products to extend the insulation effect, and the insulation effect will also be different.
Material and design affect price
The price gap of insulated cups on the market is so large, what is affecting the quality and price of insulated cups? Industry insiders explained that the first is the material of the cup. At present, the mainstream material in the vacuum cup market is stainless steel, which will add heavy metals such as nickel and chromium. Generally speaking, the vacuum cup with high quality and high price produced by qualified and regular manufacturers is made of standard medical grade stainless steel, that is, 304 stainless steel. This stainless steel has the advantages of high strength, stable performance, strong acid resistance and alkalinity, and qualified products are harmless to human body. Some low-quality products with low prices may use stainless steel of other specifications. Although these products may have relatively poor color, light weight, soft hardness and other shortcomings, which do not affect the basic use, they may have potential hazards such as excessive heavy metals or precipitation, affecting human health.
Second, the product is specially designed to extend the thermal insulation effect. General Stainless steel insulation cup The vacuum layer isolation principle between two layers of stainless steel is simply used for heat preservation. Some brands of insulation cups have copper plated on the outer wall of the tank, which improves the heat preservation performance by taking advantage of the good temperature gathering effect of copper.
Huang Dapeng said that the technology of stainless steel insulation cups is relatively mature. Whether it is domestic or imported products, the principle of heat preservation of commercially available stainless steel insulation cups is basically the same. Although the above two points affect the quality of insulated cups and the price of products to a certain extent, the retail price of qualified insulated cups that can meet the standard is about 100 yuan. "Some insulating cups are exorbitantly expensive, or just brand effect."
Pay attention to the product information
How should ordinary consumers choose and buy insulated cups? Huang Dapeng reminded that consumers should pay more attention to health when purchasing insulated cups. Because consumers cannot directly distinguish the material of the cup like experts, it is best to choose qualified and regular brand products.
Second, look at the material. When purchasing, pay attention to the packaging information of the product. Generally speaking, the package or body of the cup has a chemical mark of the cup material. Although different brands of insulation cups may differ slightly according to their use, it is reasonable to use 304 stainless steel or austenitic stainless steel and other stainless steel within the medical grade range.
Third, select products with relatively good heat preservation effect. Consumers can select suitable heat preservation cups in terms of capacity, cup diameter, cover, etc. by referring to the factors that affect the heat preservation effect. The manufacturer of the thermos cup suggested that consumers do not need to blindly pursue large capacity. Generally speaking, 350ml-500ml is enough for office use. If you have children at home and need to go out frequently, you can choose a 500ml - 1000ml cup if you want to bring more hot water. He also suggested that if consumers choose oversized thermos cups, they must choose those with auxiliary handles instead of relying on straps or hand holding alone. "It is very heavy after being filled with water, so prevent scalding and slipping."
