Problems solved by technology

Among them, the supercritical drying effect is the best, but the supercritical drying airgel mat cannot achieve continuous production, and the investment cost of equipment is high.
High-temperature supercritical drying is more dangerous. The heating method adopts heat transfer oil or direct electric heating. The heat transfer efficiency of heat transfer oil is low. Direct electric heating has high requirements on the performance of the drying kettle. Due to the high temperature supercritical, the sealing requirements of the drying kettle are very high. At this stage It is still rarely used; freeze-drying, because the freezing process consumes a lot of energy, and the volume change in the solvent phase change process will cause certain damage to the gel void structure, the investment cost is large, and it is basically not used in industry at present.

Description

technical field [0001] The invention relates to the technical field of airgel production equipment, in particular to equipment and an industrialized method for continuous production of airgel blankets. Background technique [0002] In the past airgel felt production process, the production of airgel felt was often produced intermittently, with long production cycle, high labor cost, low production efficiency of a single production line, and the production workshop faced the risk of leakage of a large amount of organic solvents, increasing hidden dangers in production safety, and the product quality is not stable. [0003] At this stage, the common way to produce airgel at home and abroad is one-step acid or alkali method or two-step method of acid first and then alkali. The organic silicon source and inorganic silicon source are used to prepare the sol solution and then re-cured with the fiber mat. The curing methods of wet gel felt include direct immersion curing in soakin...
