【摘要】 随着镁质产品增多和功能的扩展,镁质胶凝材料产品不仅用于室内的通风管道、轻质隔墙板等,还有用于室外的检查井盖、屋面保温板。由于镁质胶凝材料是一种优、缺点都很突出的材料,因此通过掺加菱镁改性剂,克服和改善镁质产品的弊病是菱镁行业发展的迫切需要。分析了改性剂的主要作用机理及对镁质胶凝材料改性的重要作用。更多还原

【Abstract】 With increasing variety of magnesite product and extension of its function,the products of magnesite binding material can not only be used for indoor ventilation duct,lightweight partition panel and so on, it can also be used for outdoor manhole cover and roof insulation board. Since the magnesite binding material is one that has obvious merit and defect,it is in urgent need for development of magnesite industry to overcome disadvantages of magnesite product by adding magnesite modifying agent.The main mechanism of modifying agent and the significant function to modification of magnesite binding material are analyzed.更多还原
