硅烷偶联剂改性粉煤灰的制备

摘要

粉煤灰是一种工业固体废弃物，经过改性活化处理后，吸附能力大大提高，应用于废水处理中，达到以废治废，实现资源可持续利用。本文概括的阐述了粉煤灰改性技术和硅烷偶联剂的改性机理，采用粉煤灰表面改性技术对粉煤灰进行表面改性，以提高其亲油性和与其他材料的相容性。采用的改性剂为硅烷偶联剂，改性工艺为干法。本文希望得到改性后的粉煤灰，不论是对废水的处理，还是在水溶液中的分散性以及作为填料，均能得到较为理想的效果。

The preparation of silane coupling agent modified fly ash

Abstract: Fly ash is an industrial solid waste, after modified activation treatment, adsorption capacity is greatly increased, and application in wastewater treatment, using waste treat waste, realize the sustainable utilization of resources. This article summarized the modification technology of fly ash is expounded and the modification mechanism of silane coupling agent, surface modification technology for surface modification of coal fly ash using fly ash, to improve its lipophilicity and compatibility with other materials. The modifier for the silane coupling agent, modification process for dry process. Hope to get modified fly ash, this paper for wastewater treatment, or dispersion in aqueous solution as well as the packing, can get ideal effect.

Keywords: Fly ash; Silane coupling agent; Modification Technology; Active agent
