摘要
以山西某地钙基膨润土为原料,经提纯、钠化、柱撑制备了铝柱撑蒙脱石,运用X射线衍射(XRD)、傅里叶红外光谱(FTIR)、差热-热重(DSC-TG)、扫描电镜(SEM)等分析手段对产物进行系统表征。结果表明:Al柱化剂进入蒙脱石层间,柱撑产物层间距从1.280nm增大至2.007nm,经500℃煅烧1h后(001)晶面衍射峰仍清晰可见,产物经升温至900℃脱水过程中失重明显平缓,产物的微观孔洞结构明显增多。
Al-Pillarcd montmorillonite from Ca-bentonite of Shanxi was prepared, after purification, sodiumtreatment and pillaring. The products were characterized by XRD, FTIR, DSC-TG and SEM. The results showed that the pillar-solvent entered the layer of bentonite. Pillared layer spacing of the product increased from 1.280 nm to 2.007 nm. After calcined at 500℃ for 1 h, the diffraction peak of （001） crystal plane was still clearly visible. The weight loss of the product was significantly slow in the process of by dehydration heated to 900℃. The micro-pore structure greatly increased.
