Why has titanium water bottle become the premium carrier of the thermos cup industry?

In the year, insulated cups have become a treasure for health preservation. Among many materials, stainless steel insulated cups are deeply loved by people. Their price is moderate, and they can keep both hot and cold.

But the news that "stainless steel cups for brewing tea are harmful to health" has been widely spread. It is said that long-term use of stainless steel cups for brewing tea is equivalent to drinking heavy metals. The acidity and alkalinity in tea will react with stainless steel, releasing heavy metals such as chromium, which is harmful to human health. Do you feel "shivering" when you see this?

Later, some people pointed out that stainless steel cups for brewing tea are not as scary as rumored. For a moment, many ordinary people couldn't help but wonder whether they should use it or not?

In fact, the correct use of stainless steel insulated cups is not harmful, but when using stainless steel insulated cups to brew tea, remember that the water temperature should not exceed 80 ° C, because the acidity and alkalinity in tea will react with stainless steel, causing a large amount of vitamins to be destroyed, aromatic oils to evaporate, and tannic acid and theophylline to be leached out in large quantities. This not only reduces the nutritional value of tea, but also makes the tea juice bitter and harmful substances increase. Therefore, when using stainless steel cups to brew tea, the tea leaves should not be soaked for a long time.

In addition, some people like to soak traditional Chinese medicine in thermos cups for easy carrying and drinking. However, a large amount of acidic substances are dissolved in the decocted traditional Chinese medicine, which can easily react with the inner wall of the thermos and dissolve into the medicine, causing adverse effects on the human body. It is recommended that any food with unclear properties should not be soaked in the thermos, otherwise safety cannot be guaranteed.

There is now a type of titanium cup that is safe, non-toxic, free of heavy metals, acid and alkali resistant, and corrosion-resistant, becoming the "carrier" of the insulated cup industry. So, what are the characteristics of titanium insulated cups?

1. Excellent antibacterial properties

The surface of titanium is a layer of oxide film, which does not have the rust smell of metal products, nor does it cause any odor in beverages, allowing for a refreshing taste of the original flavor of food.

The mechanism of light antibacterial effect is that after titanium oxide is exposed to light, the positive holes [i] and negative electrons [ii] on its surface are released, which dissolve with oxygen contained in water to form reactive oxygen species, decompose water to produce hydrogen and oxygen. Under the action of hydrogen and reactive oxygen species, sterilization and decomposition of organic matter are carried out, while also decomposing miscellaneous bacteria, sourness, etc., thus making the taste of beverages more mellow.

Relevant personnel have conducted experiments using stainless steel and pure titanium insulated cups:

Two identical portions of orange juice and tea were placed in pure titanium insulated cups and ordinary stainless steel insulated cups, respectively. After 48 hours of testing, the tea and orange juice in the titanium cups had normal color, no odor, no bad smell, and fewer bacterial colonies; The tea and orange juice in the stainless steel insulated cup have white foam on the surface, with a sour smell, and the bacteria produced are much higher than those in the titanium cup.

2. Corrosion resistance, pack whatever you want, make tea fresher

There is a strong layer of titanium oxide protective film on the surface of titanium metal, which has extremely stable chemical properties and cannot even corrode the king of acids, "aqua regia". Therefore, pure titanium insulated cups can store acidic and alkaline beverages, strong tea, soy milk products, coffee, carbonated drinks, Chinese medicine stews, etc. for a long time without any problem, without any metal oxidation phenomenon, and are super resistant to acid and alkali corrosion.

Drinking water, titanium insulated cups are definitely the first choice for health
