What material should I choose for the thermos cup?
1, stainless steel
Stainless steel thermos cup is not easy to produce corrosion, pitting and corrosion, and is wear-resistant and durable; Nowadays, it has become a new trend of using cups in modern families. The stainless steel thermos cup is gorgeous, bright, fashionable and durable, which adds design color to our plain life. And has the characteristics of firmness, tight combination and being difficult to be destroyed; Stainless steel thermos cups are generally made of food-grade 304 stainless steel, with chromium content of 16%, good stability, strong corrosion resistance, no rust after long-term use, and the function of insulating ice water besides hot water.
2. Pottery
Ceramic thermos cups are not very common in the insulation industry, and the price will be several times more expensive than other materials. The price of a good porcelain thermos cup may reach thousands of dollars. However, ceramic thermos cups are completely harmless and will not produce harmful metal substances like other materials.
3, purple sand
At present, the inner container of some brand products of front-end thermos cups is made of authentic pure natural purple clay (less output), and the outer layer is made of stainless steel, but it is the purple sand material that makes the thermos cups have other functions, so the thermos cups with stainless steel as the outer body and purple sand as the inner container are usually called purple sand thermos cups in the industry. Besides the basic functions, it can also make tea, which has the functions of health preservation and conditioning. Strong adaptability to sudden change of cold and heat, no burst due to sudden change of temperature, slow heat transfer and no burning.
4. Glass
Glass is a very stable substance, which is sintered from inorganic silicate. Glass is easy to clean and very safe; But the glass thermos cup has a disadvantage that it is easy to break, so it is inconvenient to carry it with you.
5. Plastic
Plastic thermos cups only have the function of heat insulation, and the heat insulation effect is far from other thermos cups. Although it can be insulated, the insulation time is short and the heat dissipation is fast, which is not suitable for autumn and winter. And in the history of the development of thermos cups, many people in the industry said that plastic thermos cups are likely to contain carcinogens and need to be purchased carefully.
To sum up, the commonly used materials in the industry are stainless steel, ceramics, purple sand, glass and plastic. As can be seen from the above, stainless steel thermos cup is the best choice now. Although ceramics have high safety performance and contain no harmful substances, they are rare in the market. Purple sand has the function of heat preservation, warm in winter and cool in summer, but authentic and pure natural purple sand mud is rare. Glass has high stability, but it is not portable and fragile; Plastic thermos cups are suspected to be carcinogens, and the insulation effect and time are also very poor, so they need to be purchased carefully.
How to choose a thermos cup
1, depending on the material: there are many kinds of stainless steel, such as 20 1 steel, 202 steel and 304 steel. , commonly used in the market to make thermos cups. 304 steel is food-grade, and Sinoe thermos cups are all made of 304 steel made by South Korea's Posco, which absolutely contains no harmful heavy metals.

2, look at the technology: the skill of selecting thermos cups, thermos cups can be divided into tailless thermos cups and tailed thermos cups. Traditional vacuum cups always have exhaust tails, and tailless vacuum technology uses special technology to weld the glass mouth, so there is no sharp exhaust tail, which avoids the damage of the exhaust tail and the cup liner. Sinoe thermos cup adopts the leading tailless vacuum pumping technology and the cup body integrated molding technology, which not only ensures the thermal insulation performance but also improves the aesthetics.
3, look at the tightness: when buying a thermos cup, add water and turn it upside down to see if there is water overflowing. If not, it means that the tightness is good.
4. Look at the heat preservation performance: put in hot water and touch the surface of the thermos cup after 2-3 minutes. If there is obvious temperature rise, it means that the vacuum insulation performance has been lost.
5, look at accessories: the quality of the cup cover pad determines the sealing of the cup, and the Sinoe cup cover is made of natural silicone ring, which is extremely sealing; The material and technology of the cup bottom pad reflect the humanistic feelings of an enterprise. The anti-skid pad at the bottom of Sino Cup is made of TPR material, which is non-toxic and corrosion-resistant.
6, look at the appearance: exquisite appearance, excellent workmanship reflects a manufacturer's emphasis on quality, Sinoe's pursuit of fine details has always been strictly controlled: exquisite interface, smooth and flat thermos cup mouth, everywhere reflects Sinoe's sense of craftsmanship.
How to maintain the thermos cup?
Wash the newly bought thermos cup with boiling water and detergent. Washing with boiling water can effectively sterilize the thermos cup, which is beneficial to personal health.
In order to make the insulation effect of the thermos cup better, it is necessary to preheat or cool it for 10 minutes, and when adding hot water to the thermos cup, it is necessary to avoid overfilling, so as not to be scalded by the overflowing hot water when opening the cup. In addition, in daily life, it is best to cool the hot water to 70 degrees before filling the cup.
Excessive heavy metals will migrate from the fruit juice and carbonated drinks in the thermos, so don't use the thermos to pack fruit juice, carbonated drinks, dairy products and tea. If you use a thermos cup to make tea, the tea polyphenols in the tea will be lost, thus losing the meaning of healthy tea drinking.
Do not use steel wire mesh to clean the inner container during daily cleaning, which will destroy the insulation effect. If there are stains on the inside or lid of the thermos cup that are difficult to clean, you can clean it with neutral detergent or diluted vinegar at home.
