The effect of loading and syringing on void formation in five automixed addition silicones was evaluated by determining the voids created in the first and second halves of material loaded and dispensed from a metal syringe. Impressions were made of a model with six stainless-steel cylinders. The voids were counted at a predetermined site on 3 separate days using a binocular microscope at x 7 magnification. Automixed addition silicones did not confirm the 'last out-fewer bubbles' phenomenon and specific loading and syringing technique did not appear to have a consistent effect on void formation in automixed elastomers.
通过测定从金属注射器中装入和挤出的材料前半部分和后半部分产生的空隙，评估了加载和注射对五种自动混合加成型硅橡胶中空隙形成的影响。用一个带有六个不锈钢圆柱体的模型制作印模。在3个不同的日子里，使用7倍放大倍数的双目显微镜在预定位置对空隙进行计数。自动混合加成型硅橡胶并未证实“最后挤出气泡较少”的现象，并且特定的加载和注射技术似乎对自动混合弹性体中的空隙形成没有一致的影响。
