This study was carried out using bleached softwood Chemi-Thermo-Mechanical Pulp to evaluate the influence of Molded Pulp Products’ manufacturing process parameters on the finished products’ mechanical and hygroscopic properties. A Taguchi table was done to make 8 tests with specific process parameters such as moulds temperature, pulping time, drying time, and pressing time. The results of these tests were used to obtain an optimized manufacturing process with improved mechanical properties and a lower water uptake after sorption analysis and water immersion. The optimized process parameters allowed us to improve the Young’ Modulus after 30h immersion of 58% and a water uptake reduction of 78% with the first 8 tests done.

纸浆模塑产品工艺对漂白化学-热机械浆的机械性能的影响

这项研究是使用漂白的软木化学-热机械浆进行的，以评估模塑浆产品的制造工艺参数对成品的机械和吸湿性能的影响。用Taguchi桌子进行了8次测试，并使用了特定的工艺参数，例如模具温度，制浆时间，干燥时间和压制时间。这些测试的结果用于获得优化的制造工艺，该工艺具有改进的机械性能，并且在吸附分析和水浸后具有较低的吸水率。优化的工艺参数使我们在进行了前8次测试后，经过30小时的浸泡后，杨氏模量提高了58％，吸水率降低了78％。
