硅烷偶聯(lián)劑改性粉煤灰的制備

摘要

粉煤灰是一種工業(yè)固體廢棄物，經(jīng)過改性活化處理后，吸附能力大大提高，應(yīng)用于廢水處理中，達(dá)到以廢治廢，實(shí)現(xiàn)資源可持續(xù)利用。本文概括的闡述了粉煤灰改性技術(shù)和硅烷偶聯(lián)劑的改性機(jī)理，采用粉煤灰表面改性技術(shù)對(duì)粉煤灰進(jìn)行表面改性，以提高其親油性和與其他材料的相容性。采用的改性劑為硅烷偶聯(lián)劑，改性工藝為干法。本文希望得到改性后的粉煤灰，不論是對(duì)廢水的處理，還是在水溶液中的分散性以及作為填料，均能得到較為理想的效果。

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
