Chinese people have the habit of drinking hot water, boiling water into a cup to drink is a common thing, everyone used to use glasses, but now there are many types of cups on the market, but not every one can be filled with boiling water.
Because the boiling hot water temperature has reached 100 degrees, for some cups, filling the cup with 100 degrees of high temperature hot water is likely to turn the cup into a "poisonous cup".
Remind everyone: these 5 kinds of cups "don't fill boiling water", beware of hot water turning into "poisonous water", and tell your family quickly.
01. Enamel cups with paint off
People in the seventies and eighties used enamel cups to drink water, and the grandfather's big teapot in memory was enamel, and now this material of enamel is rare, but there are still many people in the older generation who drink water with enamel cups,
In fact, many people don't know what kind of material enamel is, it is actually an alloy material, there is a layer of paint outside, the former ceramics have now become an enamel pot, and the appearance is favored by many housewives, but enamel has a special feature, that is, it is relatively fragile, and it is easy to "drop porcelain" when bumping.
Once the "porcelain is off", it is no longer suitable for drinking water, especially when it is filled with boiling water, after "peeling off the paint", the metal substances inside will be exposed, and the boiling water will cause heavy metals to slowly precipitate out, which is not good for human health. So if you like to use an enamel cup to drink water, once the inside is bumped and damaged, you can no longer use it.
02. Glacier cups with color
The glacier cup has a super high appearance and is loved by the public, especially the gradient color of the glacier cup with color is particularly good-looking, but most of the glacier cups on the market are sprayed with color and electroplating process.
One of the big drawbacks of this process is that in the case of high temperatures, the drink is not stable and is easy to release in hot water, so it is recommended that you do not use a colored glacier cup to drink boiled water, and it is best to buy a high-quality colorless glacier cup if you like a glacier cup.
03.PC material "potbelly cup"
In recent years, this kind of potbelly cup is particularly popular, the appearance is super high, and it is lighter to use the potbelly cup when going out with water in summer, and many parents also use potbelly cups for their children at home, but in fact, this kind of cup is actually made of PC material, and the cup made of PC material can only be used to hold cold water.
If the water temperature is relatively high, when it reaches 100 degrees and is put into the cup, it will cause the precipitation of BPA material, and it will enter the human body with drinking when released in water.
The accumulation of time has great harm to health, so parents must not use PC material potbelly cup to fill their children with boiling water, although it can not be immediately harmful, but long-term use is equal to chronic poisoning.
04. Paper cups
Paper cups are more common in life, especially in some public places such as offices, banks, etc., paper cups will be prepared for drinking water, but in fact, it is not healthy to use paper cups to fill boiling water, because there is a layer of wax coating inside the paper cup, although this coating is waterproof, but the material is not healthy, and toxic and harmful substances will be released in high temperature hot water.
When using disposable paper cups, it is best not to drink the first cup of water, wait for four or five minutes to take the water away, and wait until the harmful substances in the cup are sufficient, and then use.
Paper cups and instant noodle buckets are actually the same, and the wax coating inside will release toxic and harmful substances at high temperatures, so you can try not to use paper cups to drink boiled water, and if necessary, then it is best to only use cold water in paper cups.
05 Unqualified stainless steel cups
Stainless steel materials are resistant to high temperature, corrosion, and not fragile, but be careful not to store carbonated drinks, coffee, juice, strong tea and other beverages for a long time.
In addition, other stainless steel materials are unsafe, the chemical stability is not good, hot water will release harmful substances, choose stainless steel thermos cup, in addition to the steel printed with the words "food grade 304, sus304, 316", but also pay attention to see whether it meets the national standard, stainless steel vacuum cup insulation efficiency implementation standard GB/T29606-2013.
Summary:
Not all cups can be filled with hot water, some cups are made of materials that will release toxic and harmful substances once they are filled with high-temperature boiling water, although there will be no "symptoms" immediately, but in the long run, it will definitely cause some harm to the body, don't be careless for the health of your family.
