本文经研究发现:超细加工在完成坡缕石纤维束分离的同时,将导致被缕石晶胞参数a、b、c减小,基本结构单元以连接点为支点发生一定程度的旋转,从而产生结构孔道畸变;有利于提高坡缕石对大分子吸附质的吸附能力,而不利于对小分子吸附质的吸附;使坡缕石表面断键增加,表面SiOH含量增大;导致坡缕石超细粉水溶液碱性增强、导电性离子含量增加,导电性能高于原粉;使坡缕石的流变性能优化。
In this paper, it is found that ultrafine processing can reduce the parameters a, b and c of unit cell of attapulgite while completing the separation of palygorskite fiber bundles, and the basic structural units rotate to a certain extent with the connection point as fulcrum. Resulting in structural pore distortion; is conducive to increasing palygorskite adsorption capacity of macromolecular adsorbate, but not conducive to the adsorption of small molecule adsorbate; the surface of the palygorskite increases, the surface SiOH content increases; leading to palygorskite Ultrafine powder aqueous solution increased alkaline conductive ion content increases, the conductivity is higher than the original powder; rheological properties of palygorskite optimization.
