What is the difference between glass materials in glass reactors

Sometimes when we do experimental research, we use reactors for work, and there are many types of reactors, of which the most commonly used is glass reactors.

The glass reactor uses a new type of high borosilicate glass. The borosilicate heat-resistant glass belongs to “cured glass”, which is quite expensive and fully meets the environmental protection testing standards. Due to its own high temperature resistance and instantaneous temperature resistance performance requirements, a large amount of harmful heavy metal ions such as lead and zinc in “green glass” are replaced by high borosilicate materials, so its brittleness and weight are much smaller than ordinary “green glass”, ensuring that it is instantaneous It will not explode under sudden changes in temperature. Its weight is much lighter than ordinary “green glass” which contains more heavy metal ions, and its appearance is also different from ordinary glass. Borosilicate glass is mainly used in the fields of glass equipment, daily-use glass, chemical equipment and so on.

Like the glasses we usually use, the high-quality ones are made of high borosilicate material. In fact, among all kinds of cups, the cup is healthy. Because there are no organic compounds in the glass, when people drink water or other beverages in the glass, they don’t have to worry about harmful chemicals entering the stomach. The glass surface is smooth and easy to clean, so drinking water from glass is healthy and safe.

1. Material composition: Borosilicate glass contains more boron trioxide and silicon dioxide than ordinary glass. The boron content can reach 14%, and the silicon content can reach 80%. Normal flat glass contains more than 70% silicon, and ordinary glass generally does not add boron, but sometimes more than 1% is added.

2. Glass characteristics: Gaopeng glass has low expansion coefficient, high softening point, and good resistance to rapid cold and heat. Its expansion coefficient is between 32~33*10(-7), ordinary glass reaches about 80~100*10(-7); the temperature of resistance to rapid cooling and heating is about 200~300℃.
