Which is better for sodium calcium glass and high borosilicate glass?

Which is better for sodium-calcium glass and high-borosilicate glass? Compared with the two, high-borosilicate glass is better.Sodium-calcium glass is a kind of ordinary glass. Its cup body and bottom are very thick. The main composition is composed of silicon, sodium and calcium. Although it has high chemical stability, it has poor heat resistance and is not suitable for boiling water. It can be used as a cold water cup or storage tank.So, where is the good thing about high borosilicate glass? The following is the specific content introduction. You can continue to look down.

1. The composition of high borosilicate glass is mainly silicon and boron. High borosilicate pipes and bars are a kind of special glass material with low expansion rate and high temperature resistance, with a softening point of 820℃, high thermal stability, resistance to cold and hot temperature difference of 150℃, high light transmittance, high chemical stability, high strength and high hardness.

2. High borosilicate glass can not only be made very thin and translucent, but also the body and bottom of the cup are formed in one piece, and there is no risk of cracking. It can be used as a heat-resistant glass water cup, glass tea set, etc.

3. High borosilicate glasses do not contain lead and other harmful substances. Even after being placed in water, they will not precipitate harmful substances to the human body. They are non-toxic and odorless. They are more wear-resistant and corrosion-resistant, not easy to age, easy to clean, and safe to drink.

4. When choosing a high-borosilicate glass, you should choose a high-borosilicate glass from a regular manufacturer, so that the quality of the glass will be guaranteed. At the same time, if there is a baby at home, you can also choose a high-borosilicate glass for the baby bottle.
