【摘要】 山东泰安造纸厂从1968年起一直采用中性亚硫酸铵法生产麦草浆。这种纸浆的滤永性能较好,强度较高,但不太容易漂白。制成的印刷纸符合印刷要求。长期施用该厂的制浆废液灌溉碱性土壤农田,效果很好。更多还原

【Abstract】 Taian Paper Mill has been using ammonium sulfite process for treating wheat straws since 1968-Pulps thus produced are claimed to be of better drainage and stronger strengths, but they are not very readily bleachable. Paper made with such pulps as the major furnish proves to satisfy press room requirements fairly well. Long term employment of ammonium sulfite pulping waste liquor for irrigation proves its suitability for soils of alkaline nature.更多还原
