What is the best material for a water bottle? What material is better to choose for the cup

The choice of water cup material varies from person to person, however, judging whether the water cup material is good or not is inseparable from the five poisons, no peculiar smell, and beautiful these indicators.

Theoretically speaking, the typical representative of the five poisons and no peculiar smell is the glass and ceramic water cups, but in individual cases, it is also necessary to pay attention to, such as some more characteristic glass or ceramic cups, the pattern will be printed on the inner wall of the cup, although such a cup is good-looking, but it is recommended not to buy. The advantages of ceramic and glass cups are prominent, but the disadvantages are even more prominent, that is, the resistance is poor and easy to break.

The plastic cup is not easy to break, but the PC plastic cup may have potential safety hazards, so we recommend that the best way to buy a plastic cup is to buy a No. 5 pp plastic cup or No. 7 other Tritan cup, note, here is "No. 7 other", not "No. 7 PC", you can look at the bottom of the cup when buying a plastic cup, and the plastic cup produced by regular manufacturers will be printed with similar logos. PP plastic and Tritan are non-toxic and odorless plastics, filled with boiling water, put in the microwave oven to heat it will be fine, you can search for the characteristics of these three plastics.

There is also a metal cup, and the common metal cups are made of stainless steel, especially the thermos cup, the stainless steel is relatively stable, but the common acidic drinks may affect it, so it is not recommended to use stainless steel cups to hold carbonated drinks such as cola for a long time. If you want to choose a stainless steel cup, then you must look for a 304 stainless steel water cup, generally speaking, 304 stainless steel will not cause harm to the human body.

If you want to buy a cup now is mainly fixed in the office or home to drink water, it is recommended to choose a glass or ceramic cup, if it is often taken out, it is recommended to use PP plastic or Tritan plastic cup, if you need to keep warm, then you can only buy stainless steel thermos cup.

You first choose PP material for the baby, and when the baby is older, you can choose glass material for the baby. My family treasure is like this, and now I am using the water cup of lovi is pp, because the child is too small, the glass will not be safe, and the material of pp is also very good, it is imported from Europe, which is very good.

1. Generally speaking, glasses are easier to choose and have the least hidden dangers. High borosilicate glass is usually used, and it is fired at a high temperature of more than 600 degrees. When buying a glass water glass, you should choose one with a smooth surface, no impurities, no bubbles, no peculiar smell, and no tilt in the bottle.

It is very safe to drink water from a glass.

2. The advantage of plastic water cups is that they are not fragile and easy to carry. However, it should be noted that plastic products have digital identification, 1--7, the cup that usually drinks water is generally No. 5, No. 5 plastic has the characteristics of high temperature resistance, and is not easy to produce toxic substances, and others are not suitable for use as a water cup. However, it should be noted that some water cups have a No. 5 body and a cup lid that is not, which will also produce harmful substances, so be sure to see it before buying.

3. Stainless steel water cup. There are many brands of water cups made of this material, and they are all big names. The stainless steel cup is sturdy and unbreakable, durable, and beautiful and generous, and it is more useful to the body than a thermos cup. However, it cannot be used to contain traditional Chinese medicine, as it will destroy the medicinal properties of traditional Chinese medicine.

4. Ceramic cups. The shape is diverse, beautiful and generous, but it is fragile and easy to leave water stains. Many office white-collar workers like to drink coffee, but the coffee cup needs to be special, and the glaze on the ceramic surface cannot react with the coffee, so you should choose a special coffee cup, if it is only used to drink water, it doesn't matter, the mug insulated cup can be.

Be careful not to choose a pattern on the inner wall, the pattern glaze has a certain impact on the body.

It is good to choose a cup with the right material.

Different cups of material, different uses:

1. Glass.

It does not contain harmful heavy metals and organic chemicals, and there is no need to worry about the precipitation of harmful substances in all kinds of beverages. Moreover, the transparent material is easy to clean, and it is not easy to hide dirt and dirt. Enamel cup Enamel is resistant to high temperature and corrosion, and the metal substances contained in it are relatively stable, but it may dissolve in an acidic environment, so it is best not to use an enamel cup to hold acidic drinks for a long time.

In addition, the surface of the enamel cup is easy to be damaged after being bumped, and harmful substances are precipitated, so it should be decisively eliminated.

3. Ceramic cups.

The more "plain" the ceramic cup, the safer. Because the pigment contains high levels of heavy metals such as lead and chromium, these harmful substances are easy to dissolve when water or beverages with high acid and alkaline properties are opened. When purchasing, you can touch the surface of the pattern, if it is smooth, it is safer; If it is uneven and will fall off if you pick it with your fingernails, it is best not to buy it.

Fourth, plastic cups.

The additives and low-molecular-weight substances in the plastic cup are easy to precipitate when heated. Therefore, it should be filled with as little hot water as possible, hot drinks, etc. Plastic cups should also not be kept in the refrigerator for a long time, as low temperatures will cause plastic degradation.

In addition, plastic cups are also very easy to breed bacteria and hide dirt and dirt, so pay attention to frequent cleaning.
