Method for improving gelling property of inorganic solid waste 3D printing material
The invention discloses a method for improving the gelling property of an inorganic solid waste 3D printing material in the technical field of 3D printing, which comprises the following steps: taking natural shale and clay minerals with high gelling property as a binder, adding 60-80% of inorganic solid waste, and stirring the raw materials in a stirring device; enabling the raw materials to form paste with a gelling property through a hydration reaction; then carrying out vacuumizing treatment; the paste is fed into a 3D printer to be printed and formed; and carrying out later-stage heating treatment to finish a melting reaction, so that the product forms an inorganic material product with a stable structure. Natural shale and clay minerals with high gelling property are used as binders, the amount of added inorganic solid waste reaches 60-80%, and more gelling substances are released in the stirring, hydration reaction and melting reaction processes. The gel property of the paste and inorganic material products can be improved, so that the paste and inorganic material products have better strength and stability. The problems that a 3D printing material developed by utilizing inorganic solid waste is poor in gelling property and difficult to print and form are solved.
本发明公开了3D打印技术领域的提高无机固废3D打印材料胶凝性的方法，采用胶凝性高的天然页岩和黏土矿物作为粘结剂，配入无机固废量达到60‑80％，将原料放入搅拌装置中进行搅拌；通过水化反应使原料形成富有胶凝性质的膏体；再进行抽真空处理；将膏体送入3D打印机中进行打印成型；进行后期加热处理，以完成熔融反应，使产品形成具有稳定结构的无机材料产品。通过使用胶凝性高的天然页岩和黏土矿物作为粘结剂，配入无机固废量达到60‑80％，在搅拌、水化反应和熔融反应过程中释放出更多的胶凝物质。这有助于提高膏体和无机材料产品的胶凝性质，使其具有更好的强度和稳定性。解决了利用无机固废开发3D打印材料存在胶凝性差，不易打印成型的问题。
