Spirulina-containing 3D printing wire material and preparation method thereof

Abstract

The invention discloses a spirulina-containing 3D printing wire material and a preparation method thereof. The 3D printing wire material comprises the following components in percentage by weight: 59-91% of matrix resin, 8-40% of spirulina and 0.05-2% of white oil. The preparation method comprises the following steps: (1), drying; (2), weighing materials; (3), kneading at high speed; (4), performing melt granulation; (5), performing melt extrusion; (6), cooling and drawing; (7), reeling; (8), printing into a specific structure by an FDM technology. According to the invention, a prokaryotic organism is introduced, the prokaryotic organism is rich in functional groups, can be bonded with dye molecules or heavy metal ions, and is low in price, and a porous supporting skeleton for tiny particles is prepared by the efficient and accurate FDM technology. The spirulina-containing 3D printing wire material is simple in preparation process and low in energy consumption, overcomes the defect ofsecondary pollution caused by the difficulty of separating an adsorbent from a solution after a dye is treated with polysaccharide in the forms of solution, powder, microspheres and gel when used as the adsorbent, has certain recycling performance, and realizes green circulation and efficient utilization of the material.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a 3D printing wire containing spirulina and a preparation method thereof. Background technique [0002] Water pollution caused by heavy metals and dyes has been a growing global 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. It is very important to remove excess heavy metals from natural water. Traditional methods such as chemical precipitation, ion exchange, adsorption, and reverse osmosis are commonly used methods for heavy metal removal, but the use of these methods is limited due to technical or economic constraints. Therefore, it is crucial to explore the use of potential materials with strong tolerance and adsorption capacity for heavy metals. Dye wastewater treatment also includes a...
