linear macromolecule

By changing quenching conditions, increasing spinneret hole, employing disc melt filter and adding additives, the macromolecular linear regularity can be improved to such an extent that the breaking strength of tire cord increases to over 88 3 c.

在尼龙 66工业丝生产中 ,采取降低后聚合器至纺丝箱之间管道温度 ,降低纺丝箱温度 ,调整尼龙 66盐液 p H值来提高聚合熔体粘度 ,采取改变侧吹风冷风条件 ,增加喷丝板孔数 ,采用盘式熔体过滤器、添加助剂等方法提高大分子线性整列度 ,使帘子线断裂强度达 88。

Moreover,the corresponding results of the multilinear fractional maximal operator are obtained.
