"What are you doing? I've been making tea in this cup for years, so don't always listen to the rumors on the Internet." The company's main business is to provide a wide range of products and services.
"People have been exposed by CCTV, the insulation cup is toxic, the heavy metal inside exceeds the standard, it will not be poisoned and will cause cancer, is this still false?"
"You said this is reliable in the end," heard his partner say, Li was a little scared.
In daily life, many people like to use insulation cup to make tea or bubble wolfberry health, that insulation cup in the end is not safe, but also can not use?

A, insulation cup "hot water into, toxic water out"? Experiment to tell you the answer

CCTV did expose a number of "life-threatening insulation cup", the Beijing Consumers Association researchers on the market 50 kinds of brands of insulation cup test, the test found that the heavy metal content exceeds the standard insulation cup is 19 kinds, many people are therefore worried about the use of insulation cup will be hazardous to health. Insulation cup is really as rumored, will be "hot water into", "toxic water" out?
On the Internet about insulation cups soak tea will be poisoned argument is widely spread, rumors say that after the tea will produce tea scale, these tea scale attached to the inner wall of the insulation cup, will lead to corrosion of the inner wall, so that the heavy metals in stainless steel leaching, people will lead to poisoning after drinking.
Professor Ren Yibin from the School of Materials Science and Engineering at Shenyang University of Technology said that according to the national standard GB9684-2011, there are clear requirements for stainless steel materials for eating utensils, which strictly limit the amount of lead, cadmium, arsenic and other metal elements that can be dissolved, so there is no need to worry too much.
Some scholars have conducted experiments specifically on this, and the test conditions are almost impossible to encounter in life.
In addition, the Institute of Product Quality Supervision and Inspection of Yiwu City Market Supervision Bureau had also done an experiment.
The researchers selected nine teacups and three tea filters as samples, all of which were made of different materials, and seven of them were insulated cups. The tea was then filtered out and poured into test tubes to test for heavy metals such as lead, arsenic, cadmium and chromium in the tea.
The results showed that the heavy metals precipitated in the 12 teas were very trace. The normal daily use of insulation cups will not have heavy metal precipitation, and even if there is precipitation, it is very trace, will not affect health.

Two, insulation cup, plastic cup, glass cup, enamel cup, in the end, which cup is safe?

Many people are concerned about how much water they drink a day, but ignore the cups that hold the water. If you don't choose the right cup, drinking water may also be risky. Different people like to use different materials of cups, stainless steel, glass, plastic, enamel, etc. The materials vary, and so do the advantages and disadvantages, which material is better for drinking water?
Stainless steel is heat-resistant, corrosion-resistant, unbreakable and other characteristics, in the use of attention can not be installed carbonated drinks, coffee, juice and other beverages. At the same time, note that it cannot be filled with tea, vegetable soup, soy sauce, etc. for a long time. These drinks made of acidic materials tend to precipitate heavy metals within the stainless steel.
Glass is the safest of all materials, mostly made of inorganic silicates fired at high temperatures, which are chemically stable and easy to clean, but the only drawback is that it is fragile. The only downside is that it is fragile. When using it for the first time, you should be careful not to pour hot water directly into it, otherwise it will easily cause bursting, and it is recommended to pour a little hot water into it first to warm it up.
Plastic cups are commonly made of polypropylene, polycarbonate, the former is very heat resistant and can be used in the microwave, the latter is not suitable for hot water, and can not be exposed to high temperatures, otherwise it is easy for harmful substances to precipitate. The latter is not suitable for hot water and cannot be exposed to high temperatures, otherwise it is easy for harmful substances to precipitate. There are also many gaps in the plastic cups, which make it easier to hide dirt.
Enamel cups can be divided into three main types of colorless glaze, underglaze and overglaze, where the main component of the colorless glaze is ceramic, this glaze will not have any harmful substances precipitated, daily hot water and tea can be; underglaze is the first pigment and then high-temperature calcined ceramic cups, pigments in the glaze below, this cup brewing hot water will not precipitate The underglaze color is the pigment applied on top of the ceramic, which may precipitate harmful substances when used, and is generally not recommended.

Three, how to choose a qualified insulation cup? Remember these 5 points

Choose a qualified insulation cup is very important, in the purchase to pay attention to these things, each point is very important.
One look at the label: choose insulation cup to check whether the outer packaging has the type of material, material composition, manufacturer's name/phone/executive standard and other words.
Two look at the material: insulation cup liner material preferred 304/316 material, pay attention to see if there is a clear logo, other materials as long as they meet national standards can also be selected.
Three look at the appearance: good quality insulation cup cup surface, welding and lid switch button, etc. should be normal, there will be no lid does not fit and other issues arise.
Four smell: good quality insulation cup smell is no odor, or the smell is relatively light easy to disperse, if you open the smell is very heavy, then there may be a risk of use.
Five look at insulation: after a long time holding hot water, the higher the insulation temperature, the better the performance.
There are very many rumors about insulation cups, but many are not credible, learn to identify this, do not affect their normal life.
