Abstract
The invention relates to a treatment device for improving the water delivery performance of a PVC type hydrogel photo-thermal evaporation material. The treatment device comprises a piercing processingdevice, a surface repeated thermal deformation processing device, a surface grinding sweeping treatment device and a surface hydrophilic modification treatment device; the piercing processing devicecomprises a piercing tool, perforating holes, a hydrogel and a low-density high-strength material plate, the hydrogel is placed on the low-density high-strength material plate, and the hydrogel is pierced through the piercing tool to form the uniformly distributed perforating holes; and the surface repeated thermal deformation processing device comprises an aging lamp and deionized water, and thepierced hydrogel is placed under the aging lamp. The treatment device has the beneficial effects that the vertical and horizontal water conveying capacity of a gel material is improved through the piercing processing device and a series of horizontal water conveying modification combined treatment devices, the moisture evaporation rate under the same condition can be greatly improved, the photothermal utilization efficiency is obviously improved, and the treatment process is environment-friendly, pollution-free, simple and easy to operate and low in cost.
Description
technical field [0001] The invention relates to the fields of hydrogel, photothermal evaporation, material modification and surface treatment, in particular to a treatment device and method for improving the water conductivity of PVC hydrogel photothermal evaporation materials. Background technique [0002] At present, seawater desalination technology is being widely concerned and applied. Due to the influence of natural evaporation rate, photothermal seawater desalination technology has not been fully developed. Many research teams at home and abroad pay attention and research. PVC-based hydrogel is a hydrophilic polymer synthesized with polyvinyl alcohol (PVA) as the main monomer and aldehydes. The polymer material has a cross-linked spatial network structure, and the photothermal material and The gel photothermal evaporation material (hereinafter referred to as the gel material) can be obtained by coupling the hydrogel. The interfacial evaporation of water can be realize...
