Aerogel felt and method for producing same
The present invention relates to an aerogel felt and a method for manufacturing the same, in which a catalytic sol is sufficiently and uniformly impregnated into the felt in an impregnation tank, and the catalytic sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalytic sol can be easily introduced into the felt, thereby forming a uniform aerogel in the felt. As a result, the uniformity of the pore structure and the thermal insulation performance of the aerogel felt thus manufactured are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.
本发明涉及一种气凝胶毡及其制造方法，其中，在浸渍罐中催化溶胶充分且均匀地浸渍到毡中，并使催化溶胶在浸渍罐中停留特定时间以控制流动性，同时实现催化溶胶可以容易地引入到毡中的粘度，从而在毡中形成均匀的气凝胶。结果，由此制造的气凝胶毡的孔结构的均匀性和隔热性能得到改善，通过浸渍过程减少原料的损失，减少工艺问题的产生，并且减少粉尘的产生。
