Glass is a drinking appliance that is frequently used. Do you know that not all glasses can heat water. With the continuous development of science and technology, the glass industry also tries its best to develop higher quality glass. Therefore, there are many kinds of glass glasses on the market, and even produce glasses that will not break after adding boiled water. The following is the reason why glass heating water is easy to break analyzed by Haoshun glass manufacturer.
First of all, we should know that not all glasses will break when they encounter hot water. But why do some glasses break?
In the past, when buying a glass, the salesperson would tell you whether it was a hot water cup or a cold water cup. The cold water cup was the one that would break when encountering hot water; The hot water cup won’t. But now the glasses should be hot water cups. Especially in China, we all use glasses to make tea, so it’s a good thing that glasses can’t touch hot water. The boiling temperature of water under an atmospheric pressure is 100 degrees Celsius. In our daily life, we won’t have more than 100 degrees of water
If thermal expansion and cold contraction are the main reasons, all glasses should break when they encounter hot water. This is not the case. Therefore, thermal expansion and cold contraction is part of the truth. In the process of making glasses, it is also a very important reason that they are not properly treated and made right. As long as the thermal expansion coefficient of glasses is relatively small, And make the heat transfer coefficient larger, so that the glass won’t break. If you can toughen the glass, it won’t break.
