High-performance anti-corrosion cement mortar lining material for nodular cast iron pipe and lining preparation method
The invention provides a high-performance anticorrosive cement mortar lining material for a nodular cast iron pipe. The high-performance anticorrosive cement mortar lining material comprises the following components in parts by mass: 100 parts of cement, 10-80 parts of an active admixture, 0-10 parts of gypsum, 0.01-5 parts of a water reducing agent, 0-15 parts of an early strength agent, 0.01-20 parts of an expanding agent, 0.01-20 parts of a plastic retaining agent, 0-100 parts of a powder filler, 10-200 parts of quartz sand and 14-70 parts of water. The invention also provides a preparation method of the nodular cast iron pipe high-performance lining, which comprises the following steps: S1, weighing the components, adding the quartz sand, the powder filler, the cement, the active admixture, the gypsum, the water reducing agent, the early strength agent, the expanding agent and the plastic retaining agent into a stirrer, and adding water for stirring to obtain the nodular cast iron pipe high-performance anticorrosive cement mortar lining material; s2, a lining material is evenly distributed into the nodular cast iron pipe, high-speed centrifugation is conducted on the nodular cast iron pipe, and a lining layer is formed on the inner wall of the nodular cast iron pipe; and S3, after standing is conducted for a preset time, a water-based permeable inorganic protective agent is evenly sprayed to the surface of the lining layer, and the high-performance lining of the nodular cast iron pipe is prepared.
本发明提供了一种球墨铸铁管高性能防腐水泥砂浆内衬材料，包括以下质量份组分：水泥100份，活性掺合料10‑80份，石膏0‑10份，减水剂0.01‑5份，早强剂0‑15份，膨胀剂0.01‑20份，保塑剂0.01‑20份，粉末填料0‑100份，石英砂10‑200份，水14‑70份。本发明还提供了球墨铸铁管高性能内衬的制备方法，包括以下步骤：步骤S1，称取组分，将石英砂、粉末填料、水泥、活性掺合料、石膏、减水剂、早强剂、膨胀剂、保塑剂加入搅拌机，加水搅拌，得到球墨铸铁管高性能防腐水泥砂浆内衬材料；步骤S2，将内衬材料均匀布料至球墨铸铁管内，对球墨铸铁管进行高速离心，在球墨铸铁管内壁上形成衬层；步骤S3，静置预定时间后在衬层的表面均匀喷涂水性渗透型无机防护剂，制备得到球墨铸铁管高性能内衬。
