摘要
应用玻璃清洗剂和TiO2试剂对载玻片表面进行预处理，将其按照不同角度（与水平面夹角）放置一定时间进行采样，研究不同时间载玻片表面沉积、粘附粉尘微颗粒的规律和清洗的难易程度，以便分析不同试剂预处理玻璃表面的防尘效果和清洗粘附粉尘的功效及其影响因素。研究发现：1）在相同条件下，经过试剂预处理的载玻片表面粘附的粉尘比较容易清洗干净，玻璃表面经预处理后具有一定防尘保洁功能。2）载玻片粘附粉尘的时间越长，越难清除。3）夹角为0°、45°时，清洗前后栽玻片的粉尘微颗粒总数变化与采样时间成正比关系，夹角为90°时则不明显，说明后者主要以物理化学粘附为主，比前者重力自然沉降粘附作用力大，不易清除。4）微颗粒平均粒径与采样时间、放置夹角和试剂类型没有明显关系，粒径主要集中在12～22μm，遮光比的变化与载玻片粘附的微颗粒总数变化类似。
The surface of glass slides was treated by various cleaning agents （ Glass cleanser and TiO2 agents）. These glass slides were placed in different angles with horizontal level in a room. The regulation of dust sediment and the adhesion on the surface of glass slides as well as the cleaning results was investigated. Accordingly, the effects and relevant factors of dustproof and cleaning of various cleaning agents treated on the glass surface were analyzed. The testing results show that： 1 ） In the same conditions, the glass slides treated by cleaning agents and adhered dust are easily cleaned comparing with the case of no treating. 2） The longer of the adhesion time of dust on the glass surface is, the more difficult for dust to be cleaned. 3 ） The dust amount on the glass surface is proportionally to the sediment time when the angle of glass slides is 0° and 45°, but it is un - obvious at 90°. It means that the adhering force is mainly physical - chemistry action. It is more powerful than gravity sedi-mentation and it is more difficult to wipe dust off from the glass surface. 4） The average particle size is independent of sediment time, the angle of placing and cleaning agent type. The dust size distribution mainly centralizes from 12 to 22μm. The variation of light passing ratio through the glass slides is proportionally to the variation of the dust amount adhered on the glass slides.
