bulk shrinkage 中文意思是什麼
bulk shrinkage
解釋
體縮-
It requires compatible part and support materials, subject to the constraints of the deposition and removal processes. the constraints on part and sacrificial support materials were identified and a compatible material combination was developed : unsaturated polyester and wax. some other investigation is conduct, such as the effect of additive on the cure of polyester, the effect of the filling on strength and shrinkage. the part strength is determined both by the bulk material properties of the part materials and by their interlayer bonding
從分析材料的選擇機制出發，本文經過大量的實驗分析，選擇了一組較好的材料組合：不飽和聚酯樹脂與蠟的組合，通過實驗分析了引發劑、促進劑對其固化過程的影響以及填料對其強度和收縮率的影響，通過測試，分析了材料的粘接強度，為工藝實現提供重要依據。 -
