Everyone knows that water is very important, and everyone needs to drink more water to be healthier. All along, we have been concerned about how much water we drink every day, but we have ignored the containers that hold water.
Different people like to use drinkware made of different materials, such as plastic, glass, stainless steel, and so on. The advantages and disadvantages of different materials vary, and which materials are more salable, and what are their differences?
Here, I would like to recommend a few of our very popular cups:
①Stainless steel bottle
②glass cup
③Plastic bottle
①Stainless steel bottle
Stainless steel cups are resistant to corrosion, abrasion, and are not fragile. They are widely used as insulation cups, making them the first choice for modern people’s cupware.
Be careful:
Do not use stainless steel cups for acidic drinks, such as juice, coffee, carbonated drinks, etc; It is also not allowed to keep soy sauce, vinegar, vegetable soup, tea, etc. for a long time.
When washing stainless steel cups, do not use strong alkaline or oxidizing chemicals such as soda, bleach, etc
②glass cup
Of all materials, glass is relatively the safest. Glass water cups are usually made of inorganic silicates and fired at a high temperature of over 600 degrees. Due to their relatively stable chemical composition, no harmful substances will be generated during the firing process. Moreover, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the glass wall.
The glass itself does not have a color, and there are two possibilities for the production of colored glasses: A natural color, which originally contains some minerals in the glass making process, making the glass colored; Most colored glasses are made by adding pigments during processing, and these pigments generally contain heavy metals. But color cannot be used as a reason for a problem with the glass.
Be careful:
The first time a glass is used, it is afraid of bursting due to boiling water. You should first pour in a little hot water, gently shake the glass to preheat it, and then pour in hot water to use.
③Plastic bottle
Many people worry that plastic water cups can cause cancer, but as long as you choose a brand that meets national quality standards, it is relatively safe.
Generally speaking, the bottom of a plastic cup is printed with numbers 1-7. The higher the number, the higher the quality. Common materials are No. 5 PP (polypropylene) and No. 7 PC (polycarbonate).
The PP cup has good heat resistance, a melting point of 167 ℃, and stable chemical properties. It is the only plastic material that can be put into a microwave oven; “PC water cups cannot hold hot water and should not be exposed to sunlight, as high temperatures may release toxic bisphenol A.”.
Be careful:
Although the surface of the plastic cup looks smooth, there are actually many gaps, which are easy to hide dirt and accept dirt; And plastic cups are easier to absorb dust and bacteria.
