基于渗透处理的3D打印岩石试样力学特性研究

RESEARCH ON MECHANICAL PROPERTIES OF 3D PRINTED ROCK SAMPLES BASED ON PERMEATION TREATMENT

  • 摘要: 3D打印技术应用于岩石试样制备有着诸多优势,但也存在着传统3D打印材料无法完美模拟岩石材料、3D打印类岩石试样强度偏低和3D打印类岩石试样后处理技术较少等不足。为了使3D打印技术能更好地应用于岩石试样制备,本研究尝试以某典型砂岩真实矿物组成配置的矿物粉末为打印材料,通过3D打印技术制作出2种不同级配的类岩石试样,并探究渗剂渗透后处理方法对3D打印类岩石试样力学特性的影响。研究结果表明:以矿物粉末为打印材料,按不同颗粒级配下制作出的试样的力学性能有很大差异,以水性氨基树脂对3D打印类岩石试样进行渗透处理能进一步提升试样的单轴抗压强度,树脂渗透试样在抗压强度以及破坏模式上与致密砂岩相似。研究成果为通过3D打印制备岩石试样提供了新思路。

     

    Abstract: The application of 3D printing technology in the preparation of rock samples has many advantages, but there are also shortcomings such as the inability of traditional 3D printing materials to perfectly simulate rock materials, low strength of 3D printed rock samples, and limited post-processing technology for 3D printed rock samples. In order to better apply 3D printing technology to the preparation of rock samples, this study attempts to use mineral powder with a typical sandstone real mineral composition configuration as the printing material, and use 3D printing technology to produce two types of rock samples with different gradations. The study also explores the influence of infiltration agent post-treatment methods on the mechanical properties of 3D printed rock samples. The research results indicate that there are significant differences in the mechanical properties of samples made with mineral powder as printing material and different particle sizes. Permeation treatment of 3D printed rock samples with water-based amino resin can further improve the uniaxial compressive strength of the samples. The resin permeation samples have similar compressive strength and failure mode to dense sandstone. The research results provide a new method for preparing rock samples through 3D printing.
