The material requirements of stainless steel vacuum bottle are different from those of ordinary stainless steel vacuum bottle. The material requirements of stainless steel vacuum bottle are better, and the thickness and steel content of stainless steel are higher. If these can not meet the requirements, it will directly affect the vacuum effect of the stainless steel vacuum bottle. Therefore, how to choose stainless steel vacuum bottle has become a concern of many people. Today, the author teaches you to use four identification methods to select stainless steel vacuum bottle:
1. Simple identification method of vacuum insulation performance: pour boiling water into the stainless steel vacuum bottle, tighten the cup cover, wait for 2-3 minutes, and then touch the outside of the bottle body with your hand. If the bottle body has obvious warm phenomenon, it means that the product has lost the vacuum degree and can not achieve good insulation effect.
2. Seal performance identification method: pour hot water into the stainless steel vacuum bottle, tighten the bottle cover, and then place the stainless steel vacuum bottle on the table. If there is no water leaking out, it means that the sealing performance of the stainless steel vacuum bottle is good.
3. Plastic parts identification method: food grade plastic is characterized by small smell, bright surface, no burr, long service life and not easy to aging. Common plastics or recycled plastics are characterized by strong smell, dark color, many burrs, and easy aging and fracture.
4. Simple capacity identification method: the depth of the stainless steel vacuum bottle liner is basically consistent with the height of the shell, and the capacity is consistent with the nominal value. Some poor quality stainless steel vacuum bottles add sand and cement blocks to make up for the missing weight.
Finally, a brief introduction is needed in the maintenance of stainless steel vacuum bottle, which is to avoid collision and impact in the use process, so as to avoid damaging the bottle body or plastic accessories, resulting in insulation failure or water leakage. In addition, when drinking coffee, tea or drink frequently, the inner liner will change color, which is a normal phenomenon. It can be removed with toothpaste.
