摘要/Abstract

摘要： 本文研究了凹凸棒土(ATP)和纳米二氧化硅(NS)对3D打印用α半水石膏浆体泵送性、流变性、支撑性等可打印性及固化体力学强度的影响。结果表明,掺入ATP后,泵送力维持在(0.57±0.02) kN,浆体剪切应力与剪切应变曲线不随掺量增加而发生明显变化,0 h、4 h打印体坍塌角分别从空白组的24°、32°降至掺量为2.8%(质量分数,下同)时的8°、11°。与ATP相比,打印浆体掺加NS后泵送力明显增加,掺加2.8%NS浆体的泵送力是同掺量ATP浆体的近2倍,浆体剪切初始应力随NS掺量增加而增大。虽然掺加NS使浆体泵送阻力增大,NS较ATP对打印体的支撑性却明显提升,掺加2.8%NS打印体0 h、4 h均无明显坍塌。ATP和NS在1%~2%掺量时浆体均可打印,且固化打印体抗压强度均有所增加,但层间粘结强度均削弱约2/3。

Abstract: In this paper, the effects of attapulgite (ATP) and nano-silica (NS) on printability such as pumpability, rheology, buildability as well as solidified sample strength of α-hemihydrate gypsum plaster for 3D printing were investigated. Results show that the pumping force of plaster with ATP remains at (0.57±0.02) kN. The shear stress against strain rate curve does not change much with ATP addition. The 0 h and 4 h collapse angles of the printed plaster with 2.8% (mass fraction, the same below) ATP decrease from 24° and 32° to 8° and 11°, respectively. In comparison to ATP, the pumping force increases by the addition of NS. The pumping force of the plaster is nearly doubled with 2.8% NS in comparison with the plaster with ATP of the same additive content. Meanwhile, the initial shear stress of the plaster with the increase of NS addition also increases. Although the addition of NS leads to the increase of the pumping force, the buildability of the plaster with NS is better than the plaster with ATP. 0 h and 4 h printed plasters with 2.8% NS both show little slump. The solidified plaster with ATP or NS addition amount 1% to 2% is printable, and its compressive strength is strengthened, but the interlaminar bonding strength is weakened by 2/3 compared with the control sample.
