NF减水剂是萘经磺化,与甲醛缩合而成的B—萘磺酸纳甲醛缩合物。它是目前国内外研究和应用最广泛的混凝土外加剂之一。 在我国,研究和生产减水剂的时间虽然较短,但目前生产的产品在性能和质量上已达到国际水平。天津自强化工厂、淮南矿务局合成材料厂等单位生产的减水剂,不仅在建筑部门广为应用,并收到显著的技术经济效果,而且在煤矿巷道锚喷中推广使用,同样表现出良好的技术性能。从淮南孔集矿在巷道喷浆时掺入减水剂的使用情况表明,在目前采用的干式喷浆中,掺入适量的减水剂,能够大幅度地
The NF water reducing agent is a B-naphthalenesulfonic acid nano formaldehyde condensate formed by sulfonation of naphthalene and condensation with formaldehyde. It is one of the most widely studied and applied concrete admixtures at home and abroad. In China, although the time for research and production of water reducers is relatively short, the products currently produced have reached international standards in terms of performance and quality. The water-reducing agent produced by the Tianjin Self-enhanced Plant and the Huainan Mining Bureau’s Synthetic Materials Plant not only has been widely used in the construction sector, but also has received significant technical and economic results. It has also been promoted in the use of coal mine roadway anchors and sprays. Good technical performance. The use of water-reducing agent when spraying from the Huainan Kongji Mine into the roadway shows that, in the currently used dry-type spray, the proper amount of water-reducing agent can be incorporated into the slurry.
