First is the simple identification method of stainless steel materials: There are many specifications of stainless steel materials, of which 18/8 means that the stainless steel material contains 18% chromium and 8% nickel. Materials meeting this standard are green environmental protection products that meet the national food level standards, and the products are rust proof and corrosion resistant. The color of ordinary stainless steel cup is white and dark. If it is immersed in 1% salt water for 24 hours, rust spots will appear, and some elements contained in it exceed the standard, directly endangering human health.
The second is simple identification of capacity: The depth of the tank is basically the same as the height of the shell, and the capacity (with a difference of 16-18mm) is consistent with the nominal value. Some insulation cups with poor quality add sand and cement blocks in the cup to make up for the missing weight. Mistake: Heavy cups (pots) are not necessarily good.

The third is the identification of plastic accessories: Food grade new plastic is characterized by small odor, bright surface, no burr, long service life and not easy to age. Common plastics or recycled plastics are characterized by strong smell, dark color, many burrs, and easy aging and fracture of plastics.
The last is the identification of insulation performance and sealing performance: Simple identification method of thermal insulation performance: pour boiling water into the thermal insulation cup and screw the bottle stopper or cup cap clockwise for 2-3 minutes, then touch the outer surface of the cup body with your hand. If the cup body is obviously warm, it means that the product has lost its vacuum and cannot achieve good thermal insulation effect. Identification method of sealing performance: after the cup is filled with water, screw the cork and cap clockwise, and place the cup flat on the table, without water leakage; The cup cover and cup mouth shall be rotated flexibly without clearance.
