1. Expanded graphite crystal is a typical laminar -like carbon material. Put other alien particles such as atoms, molecules, ion, and even atoms into the crystal graphite layer in physical or chemical methods to generate a new layered compound , Called inter -laminate compounds, can expand graphite. Can expand graphite and expansion graphite are different. Seal the sealing strip should choose expansion graphite.

2. After the fire -resistant glass grouting, it is divided into two cases: glass rupture and glue. The glass rupture is caused by the small and small strength of the glass, or the glass area is too large. Generally, the grouting process can be solved. That shows that the quality of the glass glue you choose, or the glass glue is caused by completely solidifying. Specific questions can leave a message for me to discuss privately.
