Abstract

The invention discloses a manufacturing method and an application method of an in-pipe intelligent water locking and leakage plugging material. The in-pipe intelligent water locking and leakage plugging material is prepared from raw materials of diatomite, sepiolite, urea and oxalic acid through steps of baking, dispersing, centrifuging, impurity removal, stirring, remixing and the like. The application method comprises selecting a specific weight of the in-pipe intelligent water locking and leakage plugging material according to the water capacity of a liquid-phase pipe, diluting the selected in-pipe intelligent water locking and leakage plugging material in purified water at over 80 DEG C, and mixing the diluted in-pipe intelligent water locking and leakage plugging material into the liquid-phase pipe. The manufacturing method and the application method of the in-pipe intelligent water locking and leakage plugging material contain no toxic substance and avoid toxic substance residue in water pipes; when leak points exist, processes of leak point detection and pipeline digging can be saved, and directly applying the in-pipe intelligent water locking and leakage plugging material can achieve leakage plugging. Meanwhile, the in-pipe intelligent water locking and leakage plugging material is short in time required for leakage plugging and easy and convenient to operate.

Description

technical field [0001] The invention relates to an intelligent water-locking leak-stopping technology, in particular to a method for manufacturing an intelligent water-locking leak-stopping material in a pipeline and a method for using it. Background technique [0002] Leakage of heating systems in Chinese cities and towns is a common problem, and the average daily water leakage in Chinese cities and towns is about 7-10% of the water supply. Because most of the water pipelines in the pipe network are buried underground and difficult to reach, it is very difficult to seal the leaking pipelines. At present, the method of digging out the leaks and then sealing them is used. However, this method first needs to judge where the leak is, then dig out the ground at the judged leak, confirm the leak and the cause of the leak, and then replace the joint or the section of pipeline for repair, or re-tighten the joint, or repair the joint. Repair by applying sealant first and then recon...
