Nodular cast iron pipe inorganic anti-corrosion lining containing glass beads and manufacturing method
The invention discloses a nodular cast iron pipe inorganic anti-corrosion lining containing hollow glass beads and a manufacturing method. The nodular cast iron pipe inorganic anti-corrosion lining isprepared by mixing inorganic anticorrosion material, water, sand and additives, wherein theinorganic anticorrosion material comprises from the following concrete components in percentage by mass: 25%-70% of cement clinker and gypsum, 10%-70% of granulated blast furnace slag and 5%-30% of hollow glass beads. According to the anti-corrosion lining disclosed by the invention, the strength of the cement mortar lining is improved, and the porosity of the lining is reduced, so that the rising of the pH value of water and the rising of the aluminum content caused by the precipitation of calcium andaluminum hydrates in the water delivery process of the cement mortar lining are reduced, and the corrosion resistance of the lining and the hygienic performance of the water are improved.
本发明公开了一种含空心玻璃微珠的球墨铸铁管无机防腐内衬及制作方法，所述球墨铸铁管无机防腐内衬由混合无机防腐材料、水、砂子和添加剂制成，所述混合无机防腐材料的具体组分质量占比如下：水泥熟料与石膏：25％‑70％，粒化高炉矿渣：10％‑70％，空心玻璃微珠：5％‑30％。本发明的防腐内衬提高了水泥砂浆内衬的强度，降低了内衬的孔隙率，从而降低了水泥砂浆内衬在输水过程中因钙及铝水化产物的析出造成的水质pH值升高及铝含量的升高，提高了内衬的耐腐蚀性及水质的卫生性能。
