How to buy stainless steel thermos cup

  Nowadays, there are many brands of stainless steel thermos cups on the market, and the prices vary greatly
How to choose a stainless steel thermos cup with affordable price, long insulation time and durability is a problem concerned by many people
Today, I will briefly introduce the skills of selecting stainless steel thermos cups 1
See the material There are many kinds of stainless steel materials
201 stainless steel, 202 stainless steel and 304 stainless steel are often used to make thermos cups on the market
The corrosion resistance of 304 stainless steel is better than 201 stainless steel, and the price will be more expensive
Therefore, most of the stainless steel thermos cups on the market are made of 304 stainless steel 2
Look at Technology The most important principle of thermos cup is to vacuum between double-layer stainless steel structures, because vacuum does not transfer heat
The vacuum pumping technology is divided into tailless vacuum pumping and tailed vacuum pumping
The traditional thermos cup will have an exhaust tail
Tailless vacuum technology is to weld the glass mouth with a special process, so there is no sharp exhaust tail to avoid damaging the cup liner due to the collision of the exhaust tail
Tailless vacuum pumping technology is more advanced and the heat preservation effect is better 3
Check the tightness Turn the cup upside down after adding water to see if there is water overflow
If there is no water overflow, it indicates that the sealing is good
The cup with good sealing will not leak 4
See thermal insulation performance Put in hot water and touch the surface of the thermos cup after 2-3 minutes
If there is obvious warming phenomenon, it indicates that the vacuum insulation performance has been lost 5
See accessories Details determine success or failure
A good thermos cup is not only technology and materials, but also the spirit of excellence in details The quality of the cup cover cushion determines the tightness of the cup
The material and technology of the cup bottom cushion reflect the humanistic feelings of an enterprise 6
Look at the appearance It depends on whether the appearance is defective, whether the workmanship is fine, whether the cup mouth is flat and smooth, and whether the appearance is exquisite and the workmanship is excellent, which reflects a manufacturer's attention to quality
Sino's pursuit of refinement of details has always been strictly controlled 304 stainless steel, also known as 18 / 8 stainless steel because it contains more than 18% chromium and more than 8% nickel, has good heat resistance and can be used as daily necessities
201 stainless steel contains manganese, which is harmful to health after long-term use If you are interested, please search: Shanghai silede Industrial Co
