Aerogel heat insulation felt, and preparation system and preparation method thereof
The invention discloses a preparation system of an aerogel heat insulation felt, a preparation method of the aerogel heat insulation felt and the aerogel heat insulation felt. The preparation system comprises a vacuumizing device, a precursor supply device and a flexible sealing container. The vacuumizing device is used for providing negative pressure, and the numerical value of the negative pressure is adjustable. The precursor supply device is used for providing a sol precursor; the flexible sealing container is used for sol vacuum infusion of the fiber felt and provided with a first end and a second end which are opposite, the first end is communicated with the precursor supply device, the second end is communicated with the vacuumizing device, and the thickness of the containing space in the flexible sealing container can be adjusted according to the numerical value of negative pressure. Therefore, the thickness of the fiber felt accommodated in the accommodating space can be adjusted. According to the preparation system of the aerogel heat insulation felt, the thickness of the fiber felt can be adjusted, and the aerogel heat insulation felt which has the required thickness, is good in uniformity and low in load and can achieve the good heat insulation performance can be manufactured.
本申请公开了一种气凝胶隔热毡的制备系统、气凝胶隔热毡的制备方法和气凝胶隔热毡。制备系统包括抽真空装置、前驱体供给装置和柔性密封容器。抽真空装置用于提供负压，且负压的数值可调节。前驱体供给装置用于提供溶胶前驱体。柔性密封容器用于纤维毡的溶胶真空灌注，柔性密封容器具有相反的第一端和第二端，第一端与前驱体供给装置连通，第二端与抽真空装置连通，柔性密封容器内容纳空间的厚度能够根据负压的数值可调节，以使得被容纳于容纳空间中纤维毡的厚度可调节。根据本申请的气凝胶隔热毡的制备系统，纤维毡的厚度可调节，有利于制造出具有需求厚度、均匀性好且负载较低的凝胶即可达到较好隔热性能的气凝胶隔热毡。
