稻草亚铵浆的可漂性

Preliminary Studies on the Bleachability of Rice StrawAmmonium Sulphite Pulping

对稻草亚铵浆先后进行H、HH、HHP不同漂白条件的尝试 ,结果表明 ,H8H2 P2 三段漂白可将稻草亚铵浆漂至 70 %SBD以上的白度 ,且成纸的主要物理指标均达A级胶印书刊纸标准。

The rice straw ammonium sulphite pulp was bleached under different conditions of H、HH、HHP. It can be bleached to a brightness of over 70%SBD with the H_8H_2P_2 procedure. The main physics targets of paper made of the bleached pulp have met the standard of A grade offset point paper.
