The size of the relative density of highホウケイ酸ガラス管depends on the type of dissolved crystal phase, so as to obtain different crystal phases according to the standard of tempering and tempering treatment. The following briefly introduces the relative density of high borosilicate glass tube.



Working pressure will have a certain influence on the relative density of high borosilicate glass tube. When high boron glass bears high pressure or high pressure, the density of the glass will change greatly, and it must be under temperature. As the working pressure increases, the density of the glass will also increase. It is because the capacity of the laminated glass network structure is reduced after high pressure, thereby increasing the relative density. For example, the relative density of quartz glass will increase after it is under considerable working pressure. Therefore, after the working pressure is removed, this increase in relative density can be stored for a long time at room temperature, so this type of relative density can only be high The borosilicate glass tube is quenched again so that it can return to normal.

The influence of glass composition on the relative density of high borosilicate glass tube. When the strength of the relative density of the high borosilicate glass tube changes, in addition to the working pressure, it is also related to its structure. In the case of high pressure, the relative density of different glass composition is also quite different. Under normal circumstances, glass containing more positive ions has a large gap, so its relative density will increase greatly under pressure. However, the glass containing a lot of positive ions, because of its gap, does not change much in the relative density after charging.
