Description

Technical Field

[0002] Solid materials prepared by the sol-gel method have the characteristics of high specific surface area, high porosity, low density, and good thermal insulation performance. Therefore, they have unique and excellent properties in thermal, optical, electrical, acoustic and other aspects.

[0003] However, since the pore size of the gel is at the nanoscale and there are a large number of hydroxyl groups on the surface, capillary contraction is likely to occur, causing the gel network structure to gradually collapse and rupture, resulting in poor uniformity of the finished product. Therefore, it must undergo a gel aging process, which can fix the gel size structure, reduce surface activity, and improve stability. Currently, most porous silica, titanium dioxide and other products prepared by the sol-gel method need to be aged in an oven after precipitation is generated, or aged in a solvent. This method takes a long time, causes high pollution, and has low industrial production efficiency. To this end, we propose a drying device for gel aging. Summary of the invention
