countercurrent flow val

Productive practice and study of lateral flow vat showed that the paper's tensile ratio of machine—direction to cross—direction can be easily adjusted by employing a flow velocity reg- ulating board.

本文通过对侧流式圆网槽的研究和使用,发现控制纸料速度就能有效地改善成纸的纵横向抗张强度比,只要增设浆流均布限速板,便能灵活地调节成纸的纵横向抗张强度比。
