Abstract

The invention discloses a chlorella-containing 3D printed wire and a preparation method thereof. The 3D printed wire is composed of 59-91 parts by weight of a base resin, 8-40 parts by weight of chlorella and 0.05-2 parts by weight of white oil. The preparation method comprises: (1) drying, (2) weighing, (3) high speed kneading, (4) melting granulation, (5) melt extrusion, (6) cooling traction, (7) coiling, and (8) printing of a specific structure based on a FDM technology. The preparation method utilizes a small-sized single-cell autotrophic organism which is rich in functional groups, can becombined with dye molecules or heavy metal ions and has a low price. Through an efficient and accurate FDM technology, a porous support skeleton of fine particles is prepared. The preparation methodis simple and realizes low energy consumption. The chlorella-containing 3D printed wire as an adsorbent solves the problem that after the polysaccharide in forms of a solution, powder, microsphere andgel treats the dye, the adsorbent is difficult to separate from the solution so that secondary pollution is produced. The chlorella-containing 3D printed wire realizes green circulation and high efficiency use.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a 3D printing wire material containing chlorella and a preparation method thereof. Background technique [0002] With the development of industry and the advancement of human science and technology, the increasingly prominent problems of energy shortage and environmental pollution have attracted more and more attention. Water pollution caused by heavy metals and dyes has always been a serious environmental problem. Heavy metal ions and synthetic dyes are common toxic and carcinogenic substances. They are not easily biodegradable and accumulate in organisms through the food chain, leading to various diseases and disorders. Adsorption is the most commonly used method for this type of wastewater treatment in many researchers and engineering practices. Since the adsorbents used are mostly in the form of powder, this makes subsequent treatment difficult, causing serious secondary...
