掺硼金刚石膜电极在液晶盒残留液晶清洗中的应用研究

Application of boron-doped diamond electrodes on removal of residuary LC on LCD cell

目前液晶盒残留液晶的清洗一般采用非ODS有机溶剂的溶解或表面活性剂的乳化分散作用来去除，效果并不十分理想。应用掺硼金刚石膜电极这一现今热点研究的功能材料，提出了将金刚石膜电极电化学高级氧化技术的氧化分解作用与水基清洗剂的传质、渗透、分散作用相结合的清洗技术，并通过实验确定了K3PO4添加浓度为0．4mol，L和清洗温度为70℃的最佳关键清洗参数，能在充分发挥高级氧化作用的同时，保证水基清洗剂最佳的传质、渗透和分散作用，有效实现了液晶盒残留液晶的高效清洗。

At the present time, the removal of residuary LC on LCD cell generally depends on the solubilization of the non-ODS organic solvent or the emulsification of surfactants, but the effects of these cleaning are not very well. Boron-doped diamond electrodes is a kind of new functional material, and its application investigation is very valuable. In this paper, the Boron-doped diamond electrodes are used in the water-based cleaning agent for removal of residuary LC on LCD cell, so this cleaning technology has oxidbillity, matter transfer, osmosis and dispersancy. When the concentration of K3PO4 is 0.4mol/L and the temperature is 70℃, the effect of cleaning is the best.
