Glass products are widely used in daily life, such as windows, tableware, etc. , they have a wide range of applications. However, what is borosilicate glass processed by special process? Is borosilicate glass fragile if used in daily life? Let’s get to know each other.

1. What is borosilicate glass?

High borosilicate glass is made by using the conductive properties of glass at high temperature to melt the glass by heating inside the glass, and is made by advanced production technology. High borosilicate glass is a kind of “cooked glass”, which is quite expensive and fully complies with international environmental protection testing standards. Due to the high borosilicate material’s own performance requirements for heat resistance and resistance to instantaneous temperature difference, it is used to replace a large number of harmful heavy metal ions such as lead and zinc in “green glass”, so its brittleness and weight are much smaller than the common “green glass” in daily life. Glass”.

High borosilicate glass is an important material for making beakers, test tubes and other high-durability glass instruments. Of course, its applications are much more than that. Other applications such as vacuum tubes, aquarium heaters, flashlight lenses, professional lighters, pipes, glass ball artwork, high quality beverage glassware, solar thermal utilization vacuum tubes, etc. At the same time, it has also been applied in the aerospace field. For example, the thermal insulation tile of the space shuttle is also coated with high borosilicate glass.

Second, is borosilicate glass fragile?

First, borosilicate glass is not fragile. Because the thermal expansion coefficient of high borosilicate glass is very low, only about one third of that of ordinary glass. This will reduce the effects of temperature gradient stress, resulting in greater resistance to fracture. Due to its very small deviation in shape, it has become an essential material for telescopes and mirrors, and can also be used to deal with high-level nuclear waste. Even if the temperature suddenly changes, borosilicate glass is not easy to break.

In addition, high borosilicate glass has good fire resistance and high physical strength. Compared with ordinary glass, it has no toxic and side effects, and its mechanical properties, thermal stability, water resistance, alkali resistance and acid resistance have been greatly improved. Therefore, it can be widely used in chemical, aerospace, military, family, hospital and other fields. Can be made into lamps, tableware, standard plates, telescopes, washing machine observation holes, microwave ovens, solar water heaters and other products. , with good promotion value and social benefits.

All in all, the above is about high borosilicate glass, I believe you already have a specific understanding. At the same time, borosilicate glass is something that cannot be broken. For this reason, please use it with confidence when purchasing related products.
