There are many kinds of cups for drinking water in daily life, such as ceramic, glass, plastic and paper cups, and so on. There are many types of glass cups, and the following is about the types of glass cups.
1. [Soda lime glass]
The glass water cup is made by firing an inorganic silicate material, and during the whole production process, it does not contain organic chemicals. Soda lime glass has a relatively low production cost and is an ordinary glass cup, so its price is also relatively cheap. We are also more common, but the lead content of its glass may not be well controlled. At the same time, soda lime glass cannot be heated at high temperature, so be careful when using it.
2.[Toughened glass cup]
Tempered glass is a reprocessed product of ordinary glass. Its cost is 10% higher than ordinary glass. Tempered glass is usually used as a wine glass. The rotating glass on the dining table we often see is also tempered glass, but tempered glass It is not heat resistant, can not withstand the violent changes of the surrounding temperature, and is prone to bursting. Therefore, when we use tempered glass products, we must pay attention to avoiding high temperatures.
3. [High borosilicate glass]
Borosilicate glass is completely different from the above two types of glass. It is a heat-resistant and frost-resistant material. The high borosilicate glass has a low expansion coefficient, and it will not burst in the case of sudden temperature changes. It is resistant to high temperature and acid. It also makes it difficult for high borosilicate glass to precipitate in daily drinking water, and it is not easy to precipitate and harmful to the human body Of the substance.
4. [Color glass]
Many people are concerned that colored glass is not poisonous. In fact, the glass itself is colorless, odorless and non-toxic. Most of the colored glass on the market is sprayed glass or primary color glass. These colors are compounds in which transition elements such as cobalt, manganese, nickel, iron, and copper are added during glass smelting. They react with silicate to form four-coordinate or six-coordinate complexes. Their chemical properties are very stable, and it is impossible to decompose them with boiling water at 100 degrees.
