How to Judge the Quality of Stainless Steel Insulated Cups?

Stainless steel insulated cups have become a must-have item in our lives. Whether you are a front-line worker in the workshop or an international superstar who is popular all over the world, you will use stainless steel insulated cups, but the price of the products you choose is different. The quality of the insulated cup is definitely different at different prices, so how to distinguish the quality of the stainless steel insulated cup?

1. Use stainless steel vacuum insulated cups to keep drinks cool in hot summer

Crazy people are like this. Even in the hot summer, they are keen to go shopping, exercise and toss. When going out, you might as well bring a stainless steel vacuum insulated cup. Many people may think that the insulated cup is a cup used in winter. In fact, the function of the stainless steel vacuum insulated cup is far more than that. The stainless steel vacuum insulated cup can not only keep warm, but also keep cold! Therefore, you can contain cold drinks in stainless steel insulated cups.

2. How to judge the quality of stainless steel insulated cups

First, the identification method of stainless steel material of the stainless steel insulated cup: there are many specifications of stainless steel materials, of which 18/8 means that the stainless steel material contains 18% chromium and 8% nickel. The materials that meet this standard also meet the 304 standard and are green products, which are rust and corrosion resistant. The color of the ordinary stainless steel cup is whitish and dark. If it is soaked in salt water with a concentration of 1% for 24 hours, rust spots will occur. Some of the elements contained in it exceed the standard, which directly endangers human health.

The second is the identification of capacity size: the depth of the inner tank is basically the same as the height of the outer shell, and the capacity (with a difference of 16 to 18mm) is consistent with the nominal value. Some manufacturers of poor quality stainless steel insulated cups may add sand and cement blocks to the cup to make up for the missing weight. In terms of stainless steel insulated cup, it is not necessarily the heavier, the better.

Next, it is the identification of plastic accessories: the characteristics of new plastics are little smell, bright surface, no burrs, long service life and not easy to age. Ordinary plastics or recycled plastics are characterized by strong odor, dark color, many burrs, and plastics are easy to age and break.

Then there is the identification of thermal insulation performance and sealing performance: pour boiling water into the stainless steel insulated cup and tighten the cork or lid clockwise for 2 to 3 minutes, and then touch the outer surface of the cup with your hands. If the stainless steel insulated cup is obviously warm, it shows that the product has lost the vacuum degree and cannot achieve a good thermal insulation effect. Identification method of sealing performance: after adding water to the cup, tighten the cork and lid in a clockwise direction, and place the cup flat on the table, there should be no water leakage. The lid and the mouth of the cup should be flexibly screwed without gaps.
