Abstract The mechanical characteristics of a paraffin–vegetable oil material and the compressive behavior of the powder stemming from this material were used to estimate the resistance of the compressed samples. The compressive behavior of powders under the low pressure range (1–2 MPa) applied in the candle industry was investigated in order to predict the tensile strength of the compressed samples. Compressive behavior was evaluated under lab conditions similar to those practiced in the candle industry. Compressive behavior of the powders, which represents the resistance of the particles to rearrangement during the packing step, Kp (30.98 ± 1.20 kPa of the mixture M1), was positively correlated to tensile strength of the compressed samples, σt (175.46 ± 3.61 kPa of mixture M1). Tensile strength of the compacts was also related to the mechanical properties of the raw material: high tensile strength was linked to low ductility (γMR), high mechanical strength (RMR) and high Young's modulus (E) of the material. Formulation—particularly the presence of a lubricant of mineral (0.52%) and vegetable (44.1%) origin in mixture M5—was found to strongly influence the mechanical properties of the compressed samples (σt = 115.52 ± 2.42 kPa).

压实石蜡粉末的机械性能评价。配方效果

摘要 石蜡植物油材料的机械特性和源自这种材料的粉末的压缩行为被用来估计压缩样品的阻力。研究了蜡烛行业在低压范围 (1-2 MPa) 下粉末的压缩行为，以预测压缩样品的拉伸强度。在与蜡烛行业实践的条件类似的实验室条件下评估压缩行为。粉末的压缩行为，代表颗粒在填充步骤中对重排的抵抗力，Kp（混合物 M1 的 30.98 ± 1.20 kPa）与压缩样品的拉伸强度 σt（175.46 ± 3.61 kPa）呈正相关混合物 M1)。压块的拉伸强度还与原材料的机械性能有关：高拉伸强度与材料的低延展性 (γMR)、高机械强度 (RMR) 和高杨氏模量 (E) 相关。发现配方——特别是混合物 M5 中矿物 (0.52%) 和植物 (44.1%) 来源的润滑剂的存在——强烈影响压缩样品的机械性能 (σt = 115.52 ± 2.42 kPa)。
