Preparation method of centrifugal nodular cast iron pipe with high-performance portland cement lining
The invention discloses a preparation method of a high-performance portland cement lining centrifugal nodular cast iron pipe, and relates to the field of sanitary performance of domestic drinking water conveying and distribution equipment and protective materials thereof. Comprising the following steps: S1, preparing cement mortar: selecting cement, sand and water in a proper ratio according to the specification of the cast pipe; s2, filling cement mortar: filling the prepared cement mortar into the cast pipe by using a distributing vehicle, and uniformly filling the cement mortar into a cement mortar protective layer with a certain standard thickness under the centrifugal action of a lining coating machine; s3, cement curing, wherein the pipe lined with cement is put into a furnace in time, and steam curing is started; and S4, internal grinding: after the lining is cured, performing water grinding on the cement mortar protective layer of the cast pipe, and then performing internal grinding, so that the body color of the cement mortar is exposed on the surface of the lining. According to the invention, the quality of drinking water can be obviously improved, the health of people is better guaranteed, meanwhile, social resources can be saved, and great social significance is achieved.
本发明公开了一种高性能硅酸盐水泥内衬离心球墨铸铁管的制备方法，涉及生活饮用水输配水设备及其防护材料卫生性能领域。包括如下步骤：S1水泥砂浆的制备：按铸管规格选择适宜配比的水泥、沙子和水；S2水泥砂浆的填充：制备好的水泥砂浆利用布料车将其填充到铸管管内，通过涂衬机离心作用将水泥砂浆均匀填充成具有一定标准厚度的水泥砂浆保护层；S3水泥养护：将衬好水泥的管子及时入炉，开启蒸汽养生；S4内磨：内衬养护完成之后，对铸管水泥砂浆保护层进行水磨，然后进行内磨，使内衬表面露出水泥砂浆的本体颜色。本发明能明显改善饮用水的品质，使人们的健康更有保障，同时，可以节约社会资源，具有巨大的社会意义。
