The difference between borosilic glass and ordinary glass

What is the difference between ordinary glass and high borosilicate glass?

Heat resistance

The high borosilicate glass cup is based on ordinary glass and added with boron and silicon in proportion. In the manufacturing process, glaze sodium silicate sand, soda water and lime are also added. Its strain temperature can reach 520 ℃ and its strength is also higher. There is also a lower coefficient of thermal expansion, only about 1/3 of that of ordinary glass. According to the amount of borosilicate added, borosilicate glass can be divided into three grades: high, medium and low. The title of high borosilicate glass is the same, which is also the best borosilicate glass.

So when many customers question why our high borosilicate glass water bottles are more expensive, we are helpless. Because different grades of borosilicate glass are difficult to distinguish in appearance, the simplest way is to put them together in the oven for heating, because their heat resistance is different.

To be more popular, high-borosilicate glass is more heat-resistant, and can withstand a transient temperature difference of up to 180 ℃. Low-borosilicate glass is worse, and ordinary glass is the worst, and can only withstand a temperature difference of 75 ℃.

The water just boiled is 100 ℃. If you are in an extremely cold area, the high borosilicate glass is hard to crack at a temperature difference of 180 ℃. But ordinary glass is not good. Improper use will cause cracking.

Security

The performance of glass is particularly stable. No matter ordinary glass or high borosilicate glass, glass water bottles and glass food containers will not have any harmful substances precipitated.

You must know that when I entered the laboratory in chemistry class, I found that almost all chemical reagents were contained in various glass tubes and bottles. If its chemical properties are unstable, it cannot be widely used.

Appearance

Because of its high strength, high borosilicate glass can be thinner and lighter. Of course, the only disadvantage of high borosilicate glass that I can think of is that it is expensive.

Compared with ordinary glass, high borosilicate glass has a higher light transmittance and is more crystal clear. It will not lose its luster after a long time of use, and the use experience is also better.

Just like the ordinary glass bottles used by most of our salt and pepper grinders, in short, pour the molten glass liquid into the mold for molding. Our glass water bottles and storage tanks are made of high-quality high borosilicate glass tubes, and then processed into water bottles. The high borosilicate glass baking plates are pressed.

Generally, ordinary glass will have more cold lines, bubbles and marks, while high borosilicate glass will hardly have these conditions.
