Tackifying particle for tackifying rail transit wheel-rail interface, and preparation method thereof
The invention discloses a tackifying particle for tackifying a rail transit wheel-rail interface, and a preparation method thereof. The preparation method comprises the following steps: 1, adding silica powder into water to form a premixed liquid; 2, carrying out spray drying on the premixed solution obtained in step 1 to form a particle green body; and 3, sintering the particle green body obtained in step 2 to obtain the finished product particle. The tackifying particle prepared by the invention can effectively avoid the problems of wheel rail wear and damage aggravation caused by hard particles in the tackifying process while meeting the wheel rail tackifying requirement; and tests show that the wear rate of the wheel rail material in the tackifying process is reduced by 70% compared with the traditional sand particle tackifying process, and the wheel rail sample has a smooth surface and has no obvious damage such as particle indentation and the like.
本发明公开了一种用于轨道交通轮轨界面增黏的增黏颗粒及制备方法，包括以下步骤：步骤1：将二氧化硅粉末加入水中形成预混液；步骤2：将步骤1得到的预混液经喷雾干燥形成颗粒生坯；步骤3：将步骤2得到的颗粒生坯烧结得到成品颗粒；本发明制备得到的增黏颗粒在满足轮轨增黏需求的同时，可有效避免增黏过程中硬质颗粒导致的轮轨磨损和损伤加剧的问题；经测试增黏过程中轮轨材料磨损率较使用传统砂子颗粒增黏降低了70%，且轮轨试样表面光滑，无明显的颗粒压痕等损伤。
