Description
Technical field
The present invention relates to a kind of smart lock water leakage stopping technologies, more particularly to smart lock water plugging material system in a kind of pipeline
Make method and its application method.
Background technique
Chinese cities and towns heating system leak is a universal problem, and the daily water leakage of Chinese cities and towns is average in water supply
7~10% or so.Because most pipe network water pipeline is to be embedded in underground, it is difficult to touch, to being sealed with very for leak pipeline
Big difficulty is all the method sealed again with leak source is excavated at present.However, this method first has to where judge leak source, then
The leak source ground judged is excavated, leak source and leakage cause is confirmed, then replaces connector again or the depot siding is repaired, or
Person's butt joint tighten again or butt joint at first smear sealant and the methods such as connect again again and repair.Because being difficult to accurate
Judge leak source position, usually can not find instead leak source after the ground of buried pipeline excavates, have to bury, be moved to another place again again
It excavates, until finding leak source.And often leak source has many to a set of pipe-line system, and the water leakage of single leak source may not
Greatly, also lose total water leakage even if finding several leak sources, after sealing to significantly reduce.In short, this method, efficiency are very low.
Summary of the invention
The purpose of the invention is to overcome the shortcomings of above-mentioned background technique, smart lock water blocking leakage material in a kind of pipeline is provided
Expect production method and its application method, makes its Automatic-searching leak source, leak stopping can be carried out without excavating comb line.
The production method of smart lock water plugging material in a kind of pipeline provided by the invention comprising the following steps:
S1: by the sepiolite of -250 mesh of the diatomite of -250 mesh of 50 mesh and 50 mesh using mass ratio as diatomite: sepiolite=
Mixture is placed in 180 DEG C oven-baked 24 hours by the mixing of 0.5-2 ratio, and furnace cooling obtains A material；
S2: by urea and oxalic acid using mass ratio as urea: oxalic acid=5-20, stirring and dissolving is to isopropanol and nothing at 42 DEG C
In water-ethanol, dissolved solution is slowly added dropwise in A material, ageing is spare, obtains B material；
S3: it takes 10%-20%B material to be scattered in the mixed solution of dehydrated alcohol and acetonitrile, disperses 40 minutes, in stirring bar
The ammonium hydroxide that mass fraction is 27% is added under part, obtains C material；
S4: triethanolamine being dissolved in the mixed liquor of tetra-n-butyl titanate and dehydrated alcohol, and stirring 20min is clear to solution
Clearly, mixed liquor is added drop-wise in C material dropwise under agitation, continues to stir 2h, obtain D material；
S5: taking out the pale precipitation in D material, separated, and then washs precipitating 4 times with dehydrated alcohol, precipitating is dried
Dry grinding be placed in Muffle furnace 400 DEG C of roastings remove impurity it is subsequent it is continuous be warming up to keep the temperature 24 hours under required temperature after be air-cooled to
Room temperature obtains mixing E；
S6: remaining mixed material B and mixing E are placed in batch mixer, to be stirred in the aqueous solution of 5% citric acid at 100 DEG C
It mixes, is sealed after air-cooled, obtain final products F.
The application method of smart lock water plugging material in a kind of pipeline of offer provided by the invention, intelligence in the pipeline
Energy water lock plugging material F need to hold water quality according to liquid pipe and select the specific quality of this product, then dilute with 80 DEG C of pure water are greater than
Pipeline is blended into after releasing.
The utility model has the advantages that smart lock water blocking leaks material fabrication process and its application method not in a kind of pipeline provided by the invention
Containing noxious material, detection leak source will not be had to where in water pipe residual hazard substance, when leak source occurs in pipeline,
Without excavating comb line, directly using smart lock water plugging material in pipeline provided by the invention can leak stopping, and this product
