| 摘要: |
| 目的 为了改善纸浆模塑的表观性能， 提高纸模制品的附加值。方法 研究一种双层纸浆模塑制品的成型工艺过程， 并通过正交试验研究双层纸浆模塑制品成型工艺的影响因素。结果 正交试验表明， 纸浆模塑制品的湿坯含水率和特种浆料的打浆度都能引起制品色差的变化， 最佳条件下的色差ΔE=0.41。结论 通过正交试验分别确定了 3 个条件因素对色差影响的主次顺序， 分别为湿坯含水率、 打浆度和浆料配比， 并通过极差分析确定了最佳条件因素， 湿坯含水率为15%， 特种浆料打浆度为20 °SR， 外层特种浆与内层普通浆的质量配比为0.45。 |

| Abstract: |
| To improve the surface performance and the additional value of molded pulp. his paper studied the forming process of a two-ply molded pulp product, and investigated the influencing factors of the forming process of the two-ply molded pulp product through orthogonal experimental design. The tests showed that both the moisture content of wet blank molded pulp and the beating degree of special pulp slurry caused changes in chromatic aberration of samples. The chromatic aberration was ΔE=0.41 under the optimal conditions. As revealed by orthogonal experiments, the influences of the three factors on colour difference followed the order of the moisture content of wet blank molded pulp, the beating degree and the fiber composition. And range analysis showed that the optimal experiment condition for reaching the least chromatic aberration was: a moisture content of wet blank molded pulp of 15%, a beating degree of 20 °SR and a mass ratio between outer special slurry and inner common slurry of 0.45. |
