摘要
硅在稻草中主要以粒径为１５μｍ的硅晶胞形式存在于植物外层，在制浆过程中硅晶胞作为整体溶脱后再以相对小的硅晶胞附着在纤维上．在ｐＨ值、粒子粒径和反应时间几个影响硅溶出的因素中，ｐＨ值为控制因素．硅在溶液中主要以无定形形态析出，析出的硅主要附着在纤维表面。
Silicon in straw mainly exists as silica cell in polyoliths, silica cells were of unform size and about 15m diameter. Silica cells as intact particle removed from the straw, then pricipit on the fibers with little particles than on the straws. The value of pH is control action in the three actions of pH value, particle size and reaction time. Amorphous silica is the mainly deposition form in solution, and mainly precipited on the fibers. Deposition degree and velocity increase when cation polymer presence.
