In our daily life, the glass is a very common cup. In addition to being transparent and beautiful, there are many different materials to choose from. But what is the best material for the glass?
Here are three common glass material types and their advantages and disadvantages:
Sodium-calcium glass
Sodium-calcium glass is a kind of silicate glass, the main components include silica, calcium oxide and sodium oxide. This kind of glass material has good chemical stability, high thermal stability and is not easy to breed bacteria. However, its sudden temperature difference is low, and if the hot glass is immediately placed in the refrigerator or ice water, it may cause the glass to crack. In addition, when heated in the microwave oven, the glass of this material also has a certain safety risk.
Borosilicate glass
Borosilicate glass is a kind of special glass that is resistant to high temperature and temperature difference. It has the characteristics of low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability. Even sudden cooling and sudden heating will not burst, high safety. In addition, it also has excellent fire resistance and physical strength, non-toxic side effects. However, the price of this glass material is relatively high.
High borosilicate glass
High borosilicate glass is a borosilicate glass, with excellent fire resistance and physical strength, non-toxic side effects. Its mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance and other advantages are prominent, is widely used in lamps, tableware, telescope and other fields. Compared with the borosilicate glass mentioned above, its price is more friendly to the people and more suitable for public use. Its disadvantage is that it is afraid of thermal expansion and cold contraction, and the temperature of the glass is too low to pour hot water immediately, so as not to burst.
To sum up, the selection of glass material needs to consider the use of needs and preferences. High borosilicate glass is a kind of special glass with high temperature resistance and poor temperature resistance, high safety and moderate price, which is widely used in many fields. For scenarios requiring microwave heating, borosilicate glass is a good choice, with good chemical stability and strength, and can withstand the test of sudden temperature changes.
