桉树制浆造纸性能的研究(笫三报)——柠檬桉碱法蒸煮黑液的物化性能

<正>对柠檬桉木硫酸盐法和烧碱—蒽醌法蒸煮黑液进行了化学成分全分析,测定了两种黑液浓度与总固形物含量之间的相互关系和黑液粘度与温度、浓度之间的相互关系,以及黑液固形物中碳、氢、氧、氮、硫、钠等元素含量和热值。从分析结果得到的数据看,柠檬桉木硫酸盐法和烧碱—蒽醌法蒸煮黑液可以采用传统的碱回收工艺。

STUDIES ON PULPING AND PAPERMAKING PROPERTIES OF EUCALYPTUS WOODS III. Physico-chemial Properties of the Black Liquor of Eucalyptus Citriodora in Alkaline Cooking Process

A comprechensive analysis has been made on the chemical composition of the black liquor of Eucalyptus citriodora chips in the sulfate and soda-anthraquinone cooking process. Relatons between the concentrations of two black liquors and the content of total solids, relations between the viscosity, temperature and concentration of the black liquors as well as the amounts of carbon, oxygen, hydrogen, nitrogen, sulfur, sodium, etc. and the calorific values in the solids of the black liquors have been worked out. Data obtaidne from analysis results show that alkali recovery technique can be used inthe black liquor sulfate and soda anthraquinone cooking process.
