The structures of aluminium modified silica sol(AMS) and boron modified silica sol(BMS) were investigated with IR,()~(29)Si-NMR、()~(11)B-NMR,()~(27)Al-NMR spectra and TEM(transmission electron microscopy) for the first time.Aluminium in AMS particles is mostly in the form of tetrahedron connected with ,while boron in BMS particles is in the form of tetrahedron connected with three silicon atoms or four silicon atoms.AMS and BMS present strong negative charge and the particles are amorphous whose size is about 3 nm belonging to microparticle.

Flocculation mechanism of microparticle modified silica sol(MS) retention and drainage aid system was investigated with DDJ,laser particle instrument and paper formation tester,which was a new ideal and simple method.The research results showed that fibers and fines were flocculated by adding cationic polymer and the floccules were broken up with high shear force then more chain loops and tails were exposed and bridged by negative MS.Because MS was microparticle and had high specific surface area and high negative charge density,it made close fragments flocculated into smaller and more uniform and more compact floc nets thus improving retention and drainage with excellent formation.

通过几种絮聚模型-DDJ动态滤水仪法、结合激光粒度仪研究絮团大小的变化以及纸张匀度的比较,发现硼改性微粒硅溶胶对浆料絮聚机理是先加入阳离子聚合物,使纤维与细小组分絮聚成较大的絮聚体,初始絮聚体受到高剪切力作用,被打散成小碎块,从而为带负电荷的硼改性微粒硅溶胶暴露出更多的链圈和链尾。硼改性微粒硅溶胶就在这些吸附于不同浆料粒子上的链圈和链尾之间,靠静电中和及与聚合物中非带电段的吸附作用,使近距离的细小碎块桥联而发生重新絮聚,形成较初始絮聚体更小、更均一、更致密的絮团网络。结果大幅度提高了细小纤维和填料的留着率,改善了浆料的滤水性。同时又获得了良好匀度的纸页。
