specific Embodiment approach 1

[0020] Specific Embodiment 1: The airgel drying device with the template controlling the drying point in this embodiment is composed of a drying pool 1 and a first drying template 2. The top surface of the drying pool 1 is open, and the first drying template 2 is mounted on the drying pool 1. A plurality of circular holes 3 are opened on the first drying template 2 at the top of the top.

[0021] In this embodiment, the shape and size of the drying template are determined according to the shape and size of the actual drying pool.

specific Embodiment approach 2

[0022] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the second drying template replaces the first drying template 2 and is carried on the top of the drying pool 1, and a plurality of circular holes 3 are opened on the second drying template 2, The center line of the circular hole 3 on the second drying template does not coincide with the center line of the circular hole 3 on the first drying template 2 .

[0023] In this embodiment, the circular holes on the second drying template have the same size and opening ratio as the circular holes on the first drying template. The difference is that the positions of the circular holes are completely complementary and staggered in spatial distribution.

specific Embodiment approach 3

[0024] Embodiment 3: This embodiment and Embodiment 1 are that the circular holes 3 are arranged in a rectangular array on the first drying template 2 .

Abstract

The invention discloses an aerogel drying device with a mold plate for controlling drying point positions and a method for applying the aerogel drying device, and belongs to the field of aerogel manufacturing. By the aid of the aerogel drying device and the method, the problem that large areas of existing aerogel cannot be controlled and are broken in existing aerogel manufacturing drying procedures can be solved. The aerogel drying device comprises a drying pond and the first drying mold plate. An opening is formed in the top surface of the drying pond, the first drying mold plate is erected on the top of the drying pond, and a plurality of circular holes are formed in the first drying mold plate. The method for applying the aerogel drying device includes firstly, manufacturing wet aerogel by the aid of a sol-gel process; secondly, carrying out hydrophobic modification on the wet aerogel; thirdly, erecting the drying mold plate on the top surface of the drying pond and drying the wet aerogel to obtain type-I aerogel; fourthly, manufacturing type-II aerogel; fifthly, stacking the type-I aerogel and the type-II aerogel with each other. The aerogel drying device and the method have the advantages that the aerogel in the composite fiber aerogel dried by the aid of the drying mold plate can be structurally tightly combined with fibers, cracking of the aerogel is constrained in perforated regions in drying procedures, and the problem that the large areas of the existing aerogel cannot be controlled and are broken can be solved.

Description

technical field [0001] The invention belongs to the field of airgel preparation, and in particular relates to a device for drying airgel and an application method thereof. Background technique [0002] Silica Aerogel is a controllable nanoporous amorphous material with a pore size of 1-100nm, a porosity as high as 80%-99.8%, and a high specific surface area (200-1000m 2 / g), the optical refractive index is close to 1; at the same time, because the air in the silica gel is fixed in the nanopores, it can effectively prevent the thermal movement of gas molecules, so the airgel has a very low thermal conductivity coefficient (thermal conductivity at room temperature The coefficient can be as low as 0.012W / (m·K)) It will not decompose at high temperature, and no harmful gas will be released. It is a green and environmentally friendly material. After silica airgel is combined with various heat-resistant fibers, it can be made into various forms of thermal insulation materials. ...
