Embodiment 1

[0024] The basalt fiber fabric of the present invention is a plain or twill basalt fiber fabric, in which the fibers are arranged in a cross in the warp and weft directions, and the edges of the basalt fiber fabric are edge-locked with cotton thread.

[0025] The present invention prepares the basalt fiber fabric by weaving in the weft direction, wherein the continuous basalt fiber passes through a rapier dobby carbon fiber weaving machine and uses weaving weaving technology to make plain or twill basalt fabric.

[0026] The preparation steps of basalt fiber fabric are as follows:

[0027] (1) First hang the continuous basalt fiber reel on the creel, and lead the yarn end out of the yarn guide hole of the creel respectively;

[0028] (2) Then the basalt fiber outside the yarn guide hole is intensively drawn to the yarn guide device of the rapier type dobby fiber braiding machine;

[0029] (3) Each basalt fiber is reeded, grouped and knotted, and introduced into the braiding m...

Embodiment 2

[0037] The difference with embodiment 1 is:

[0038] In the application of photothermal conversion of basalt fiber fabrics, the experimental process of modifying basalt fiber fabrics is added. Specifically, the basalt fiber fabrics are placed in a tube furnace and heated at a rate of 2°C / min in an argon atmosphere. 500°C, constant temperature for 180min and then cooling to room temperature at a rate of 2°C / min to obtain the modified basalt fiber fabric.

[0039] The photothermal efficiency of the basalt fiber fabric of comparative embodiment 1 and the modified basalt fiber fabric of embodiment 2 under different sunlight, such as image 3 It can be seen from the curve that the seawater evaporation efficiency of basalt fiber photothermal fabric is 1.2kg / m under one sunlight 2 h, after modification it can reach 1.5kg / m 2 h, under four sunlights, the evaporation efficiency is 4.9kg / m 2 h and 5.4kg / m 2 h, indicating that the light and hot water evaporation efficiency of the mod...

Embodiment 3

[0043] The difference with embodiment 1 is:

[0044] In the application of photothermal conversion of basalt fiber fabrics, the experimental process of modifying basalt fiber fabrics is added. Specifically, the basalt fiber fabrics are placed in a tube furnace and heated at a rate of 2°C / min in an argon atmosphere. 500°C, constant temperature for 180min and then cooling to room temperature at a rate of 2°C / min to obtain the modified basalt fiber fabric.

Abstract

The invention relates to the technical field of photothermal conversion materials, in particular to an application of a basalt fiber fabric in photothermal conversion. The basalt fiber fabric is placed on the surface of a foam heat insulation layer to form a photothermal conversion layer, the basalt fiber fabric / foam heat insulation layer assembly is placed on the surface of water or the water isintroduced onto the basalt fiber fabric, the evaporation of the water is promoted through the photothermal conversion heating effect, and the modified basalt fiber fabric has better photothermal conversion capability. Compared with an existing photothermal conversion material, the basalt fiber has the advantages of being high in cost performance, high in tensile strength, good in corrosion resistance, long in service life and the like, and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of photothermal conversion materials, in particular to the application of basalt fiber fabrics in photothermal conversion. Background technique [0002] With the rapid development of the world economy and technology, it has led to global climate change and serious shortage of water resources. Over the past few decades, desalination using reverse osmosis technology has become a common technique for obtaining pure water from seawater. Then, during the reverse osmosis treatment process, excessive pressure and electricity are required, and a large amount of energy is consumed in this process, thereby increasing the cost of water treatment. In recent years, the direct use of solar energy for seawater desalination technology has gradually attracted the attention of scientific researchers and advanced environmental protection technology companies. By using various photothermal materials to collect and convert sola...
