The solid on whose surface adsorption occurs is called the adsorbent . 在表面上發(fā)生吸附作用的固體叫吸附劑。
It focuses on the theory of the mineral functional materials " improving the anti - chloride permeability and the chloride binding . the main achievements of this article include : 1 ) use the technology of xrd , sem , bet , laser particle size distributor etc to test the component , the construction , particle size distributor , specific surface etc of micro - silica , ultra - fined slag , high quality fly ash , meta - kaolin clay , four types of the mineral functional material , theoretically analysis the functions which the four mineral functional minerals act on cement concrete , namely pozzolanicity effect , filling effect , micro - aggregate effect , surface adsorption effect and so bring into play the affect of plastification , lowing of temperature , reinforcement , improvement of durability . base on this analysis we can conclude that the proper diameter of the mineral functional material is 5 m - 15 m , that is blain fineness 4500cm2 / g - 7500cm2 / g 本論文的主要成果包括以下幾個(gè)方面: ( 1 )采用xrd 、 sem 、 bet 、激光粒度分析儀等多種測(cè)試手段,探明了以硅灰,超細(xì)磨?;郀t礦渣,優(yōu)質(zhì)粉煤灰及偏高嶺土超細(xì)粉等4種超細(xì)礦物功能材料的組成、結(jié)構(gòu)、粒度分布、比表面積等基本性質(zhì);從理論上分析了礦物功能材料在混凝土中的4種效應(yīng),即火山灰效應(yīng)、填充密實(shí)效應(yīng)、微集料效應(yīng)、表面吸附效應(yīng),并由此發(fā)揮出增塑、溫峰削減(降熱) ,增強(qiáng)及耐久性改善等作用;通過(guò)相關(guān)理論分析,推導(dǎo)出礦物功能材料的合理粒徑范圍在5 m 15 m ,即勃氏比表面積為4500cm ~ 2 g 7500cm ~ 2 g 。
