Extension: quality appraisal method of thermos cup
1. Simple identification method of thermal insulation performance: pour boiling water into a thermos cup, tighten the cork or lid clockwise for 2-3 minutes, and then touch the outer surface of the cup by hand. If the thermos cup is obviously heated, it means that the product has lost its vacuum and cannot achieve good heat preservation effect.
2. Sealing performance appraisal method: After the cup is filled with water, tighten the bottle stopper and the cup cover clockwise, and put the cup flat on the table, without water leakage; The rotation of the lid and the mouth of the cup should be flexible and there should be no gap.
3. Identification method of plastic parts: Ordinary plastics or recycled plastics are characterized by large smell, deep color and many burrs, and plastics are prone to aging and fracture.
4. Simple capacity identification method: the depth of the inner tank is basically consistent with the height of the outer shell, and the capacity (phase difference 16- 18mm) is in line with the nominal value. Some poor quality thermos cups will add sand and cement blocks to make up for the missing weight.
5. Simple identification method of stainless steel material: There are many specifications of stainless steel material, among which 18/8 means that the composition of this stainless steel material contains 18% chromium and 8% nickel. The materials that meet this standard are green products that meet the national food-grade standards, and the products are rust-proof and corrosion-resistant.
What are the advantages and disadvantages of different kinds of thermos cups?
1, stainless steel mug
Stainless steel thermos cup can not only keep warm, but also keep out the cold, and it is also very convenient to use in daily life. Stainless steel contains iron, which has a certain health care effect on our human body, but stainless steel thermos cups are not suitable for making tea and coffee.
2, glass thermos cup
Glass is easy to clean, so it is safest to use glass. But the glass tea set is fragile and inconvenient to use and carry.
3. Ceramic cups
There are not many ceramic vacuum cups in the vacuum flask industry. Ceramic thermos cups are completely harmless. Unlike metal cups and plastic cups, it is not possible to ingest metals and other substances after long-term use.
4, plastic thermos cup
Usually, plastic thermos cups sold in the market can only have heat preservation function, and their heat preservation function can only last for 2 to 3 hours at most. The lower the room temperature, the faster the heat will be lost. Plastic thermos cups can also be insulated, but the insulation time of plastic cups is far from that of stainless steel and ceramic thermos cups, so they are not suitable for use in autumn and winter.
5, purple sand mug
Purple sand thermos cup not only has the basic function of stainless steel thermos cup, but also can make tea, which has the function of health preservation and conditioning.
