Whether you are going out or going to work, carrying a thermos cup can instantly quench your thirst, and you can reduce the use of disposable containers. However, when using a thermos cup, you should pay attention not only before or during use, but also after cleaning. Attention, it will not be sick from the mouth!
The correct use of the vacuum flask
With the rise of environmental awareness, the use of portable thermos is becoming more and more popular, but when you choose a thermos cup, you need to buy the material of the cup that meets the standards of the Ministry of Health and Welfare, so there will be no doubt about metal poisoning. Stainless steel has different numbers according to the proportion of synthetic metal, and is divided into 200, 300, 400 series. Because of high nickel and chromium content, the series of corrosion resistance and rust prevention are currently recognized as the best series and the most widely used. If you want to choose tableware, thermos cups, etc., choose 304 and 316 in the 300 series, both of which contain 18% chromium and 8-10% nickel, but the latter will add 2 to 3% more molybdenum. Therefore, the corrosion resistance is better, and it is already a medical grade, but the relative cost is also higher, and it is mostly used in high-priced pots and scalpels. Based on cost and price considerations, most of the currently available vacuum flasks and stainless steel cutlery are "304 stainless steel".
When purchasing, please refer to the label of the product packaging, the trusted brand and the SGS inspection certificate. Daily drinks do not corrode the insulation cups that meet the inspection criteria:
For the network rumored stainless steel vacuum flask can not contain milk, tea, coffee and other acid and alkaline drinks, otherwise it will cause corrosion of the insulation cup, resulting in metal poisoning. Yang Zhenchang explained that as long as the cups meet the inspection standards, all edible drinks will not cause corrosion and damage to the body unless it is intentionally strong (such as pH less than 2, greater than 10). The liquid is soaked in the vacuum flask for a few days before the release of metallic substances. In addition, in order to reduce the weight and increase the tightness of the cup, the cup cover and the interior are mostly made of plastic, silicone and other materials. Therefore, the plastic material that meets the hygienic standard of the food packaging of the Weifu Department can be selected at the time of purchase. There will be problems with "plasticizer" and "bisphenol A"; the common plastic material is polypropylene (PP) with recycling mark No. 5 (5 in the triangle recycling mark), its heat resistance is 135 degrees, straw For other materials, it is possible to use polyethylene (PE) with recycled mark No. 2, and PE is divided into high-density polyethylene HDPE (heat resistance 90-110 degrees) and low-density polyethylene LDPE (heat resistance 70-90 degrees). 2 kinds.
There are many manufacturers for the sports, summer to introduce the cold cup, in fact, the insulation effect of the insulation cup is no different, but in order to facilitate the rapid replenishment of water, the outlet will be relatively large, so it is not recommended to install a liquid with too high temperature, so as not to burn, If equipped with a plastic pipette, also pay attention to the heat-resistant temperature indicated on the product.
Drink as fast as possible and pay attention to cleanliness:
Yang Zhenchang, director of the Department of Toxicology, said that most people need to pay attention to the problem of bacterial growth when using thermos cups. For example, most people often use milk cups for milk, coffee, etc., although the cup can slow down the temperature, but when used Repeatedly opening the cup to drink, will accelerate the loss of temperature, and let the drink touch the bacteria in the saliva, will make the drink begin to deteriorate, breeding bacteria (15 to 33 degrees Celsius bacteria most prone to reproduction). In addition, the cup should be cleaned as soon as possible after use, otherwise it will be easy to have bacteria to have the opportunity to grow. Although it is convenient to drink directly from the cup, if you want to reduce the possibility of bacterial growth, it is recommended to turn the cup into the cup and drink it.
How to properly clean the mug
Yang Zhenchang, director of the Department of Toxicology, pointed out that when cleaning the cup, the sponge can be cleaned with hot and warm water. If there is a slight scratch in the cup, the chromium oxide can still form a protective film on the surface, which will not cause the metal to be released; The mark can even drink a noticeable rust smell, which means that the stainless steel material has been damaged and the cup should be replaced. The thermos said that if the taste of the drink is too heavy, it is recommended to buy a special cleaning agent to soak it, use a sponge to lightly wash the cup; if the cup has obvious scratches, it will not only hide dirt, but also destroy the anti-rust function of stainless steel. . Every time you clean the thermos cup, you must remove all the removable plastic rings and remove them for cleaning. It should be placed for 1 night until it is completely dry before it is put back. Otherwise, it will easily breed bacteria and produce odor, when it is easy to loosen. Or when changing color, it needs to be replaced regularly.
When cleaning the thermos cup, the removable plastic ring should be removed and cleaned, and placed for 1 night until it is completely dry before being put back. In addition, stainless steel bottles, plastic parts, etc., must be kept away from high temperature materials, so the cup can not be placed in the drying machine or boiled at high temperature, so as not to cause deformation, leakage and affect the insulation effect.
