对G级油井水泥、矿渣、赤泥、压蒸粉煤灰和有机硅水解物等含有硅氧四面体结构的物质进行三甲基硅烷化 (TMS)处理 ,用气相色谱分析上述物质TMS产物中双聚体结构的特征 ,提出可以根据TMS产物双聚体的不同结构来判定胶凝物质今后的聚合趋向 .在胶凝物质硅烷化双聚体衍生物的 4种结构中 ,不对称的结构为主时 ,该胶凝物质今后有不对称的聚合趋向 ,表现出具有速凝性 ;而在胶凝物质双聚体的 4种结构中 ,线形对称结构为主时 ,线形对称聚合是它的趋向之一 ,该胶凝物胶凝相对缓慢 .
G-grade oil well cement, slag, red mud, pressure steaming fly ash and silicone hydrolysates and other materials containing silicon tetrahedral structure trimethylsilyl (TMS) treatment, the gas chromatography analysis of TMS products It is proposed that the future polymerization tendency of gelling materials can be judged according to the different structure of the dimer of TMS product.In the four structures of silanized dimer derivatives of gelling material, the asymmetric structure is In the main, the gelling material will have an asymmetric polymerization tendency in the future, showing the quick-setting property. In the four structures of the gelling substance dimer, the linear symmetry structure is the main trend, and the linear symmetric polymerization is its tendency One of the gel gels is relatively slow.
