Now many friends will buy a drinking water bottle, this is also for the convenience of family life, but in the choice of water cup or pay attention to choose the appropriate material, the water cup material sold on the market is more, such as glass cups, plastic cup, stainless steel cup, etc., this let many friends in the purchase do not tangle. So what’s a good material for a drinking cup? Let’s take a closer look.
Stainless Steel Water Bottle
Stainless steel on the market at present most of the insulation cup body material, basic is 304 stainless steel, there are a small number of pursuing manufacturers, that will use 316 stainless steel in the insulation cup liner.
Stainless steel is a kind of alloy steel, we often say stainless steel, and is actually stainless acid-resistant steel. To make steel not rust, it is actually very simple, just add some metal impurities (such as chromium) to make alloy steel. This can only do not rust, can only say that in water or air will not rust just, performance is still too poor.
To resist chemical corrosion, you need to add a lot of metals, and different formulas made of different stainless steel varieties. Such as chromium stainless steel, chromium-nickel stainless steel, and chromium-manganese-nitrogen stainless steel, which are classified according to their composition. According to the organization state classification, can be divided into Martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (dual-phase) steel, and precipitation-hardening stainless steel. Austenitic stainless steel performance is the best, and not magnetic, so in our daily life is the most widely used austenitic stainless steel.
304 VS 316
304 has strong anti-corrosion performance. It is a food-grade metal recognized by the national standard. There is no problem in normal contact with water, tea, coffee, milk, oil, and salt, etc. 316 stainless steel is upgraded from 304, such as controlling impurity ratio and adding molybdenum. so that corrosion resistance is strong and can bear various strong acids and strong alkalis. In addition, 316 stainless steel also has better adaptability to the environment. Too high or too low a temperature will not affect the corrosion resistance of 316 stainless steel. Therefore, the cost is slightly higher.
For drinking water, food-grade 304 stainless steel water bottle is perfectly adequate and has few defects.
Glass Water Bottle
It should be said that of all the materials of the cup, glass is the healthiest! No organic chemicals are used in the process of firing the glass. We worry about whether the cup is good or not, but we also worry about whether harmful organic chemicals from the cup itself will enter our bodies during drinking. Organic chemicals can have adverse effects on the human body, which is not a problem with glasses, which are relatively easy to clean and store.
What Are The Common Glass Materials?
Usually, there are three kinds, “soda lime glass,” high borosilicate glass,” and “crystal glass.”
1. High borosilicate glass water cup. High borosilicate glass does not contain lead, is safe and stable, and has high strength and high-temperature resistance. Compared with soda-lime glass, it can bear more temperature difference changes. This kind of glass is relatively light and thin, and it feels less in hand. Now many water cups are also used by us. Like the double-layer glass water cup with tea partition, the whole cup body is high borosilicate glass.
2. Sodium-calcium glass cups should be regarded as the most common glass cup in our life. Soda-lime glass is silicate glass, which has good chemical stability and thermal stability. It has no toxic or side effects in daily use, and will not cause adverse effects on health. Glasses made of this material may crack easily if the temperature difference between hot water and hot water is too large.
3. Crystal glass cup, crystal clear texture, this kind of glass is a high-end product in glass, so the price of crystal glass will be more expensive than that of ordinary glass. Crystal glass look can be identified, if you tap or play with your hand, crystal glass can send out a crisp metal sound, and crystal glass hands have a sense of massiness, the crystal glass to the light rotation when found very white, crystal clear. We often at cocktail parties can see (or in the movie, listen to its sound) the glass and touch the crisp sound, those are crystal glasses.
Plastic Water Bottle
Previous plastic cups have been controversial based on safety and health issues. Because many plastic cups used to be made of PC (a plastic material, also known as polycarbonate). PC is generally synthesized from bisphenol A (also known as BPA) and carbon oxychloride (COCl2). Bisphenol A can cause endocrine disorders, cancer, obesity caused by metabolic disorders, precocious puberty in children, etc. may be related to bisphenol A. Therefore, since 2008, the Canadian government has identified it as a toxic substance and banned it from food packaging. The European Union also believes that children ‘s bottles containing bisphenol A will induce precocious puberty and may have an impact on the health of fetuses and children.
From March 2, 2011, the European Union also banned the production of baby bottles containing bisphenol A. China also banned the import and sale of baby bottles made of PC materials or similar baby bottles with bisphenol A on September 1, 2011, which shows the safety concerns of PC. Personally, I also suggest that it is better not to choose PC materials when there is a choice. However, PC is basically not used now, and PP and Tritan materials are used instead. These two materials do not contain bisphenol A. PP, also known as polypropylene, is colorless, odorless, non-toxic, translucent, and does not contain bisphenol A. Tritan is also a chemical polyester and does not contain bisphenol A. Has passed the United States FDA certification. Relatively speaking this PP and Tritan safety is much higher, the PP temperature range is generally -30~140℃.
