moisture expansivity

This paper discusses the effect of the species and property of pulp, the moisture content of paper and relative humidity,adding filler,the density of paper and pressing and drying on the hygroexpansive strain of paper.

讨论了浆料的质量、纸张的水分含量和相对湿度、纸张的紧度、加填以及压榨和干燥等对纸张湿润胀伸缩率的影响。

Ultrasound treatment and alkali swelling were applied to activate microcrystalline cellulose (MCC) in order to improve its reactivity performance.

分别采用超声波与碱润胀对微晶纤维素进行活化,比较了两种方法对微晶纤维素(MCC)超分子结构和物理特性的影响,并通过与高碘酸钠的反应分析了不同活化方法对微晶纤维素选择性氧化性能的影响,初步探讨了其作用机理。
