Problems solved by technology

[0002] With the development of industrialization and informatization, the discharge of waste gas and waste water produced in various industries is becoming more and more serious, and the composition of industrially produced waste water is very complex, especially those with high alkalinity, which are easy to form in the pipeline when the workshop is discharged. Scale, with complex components, will form in the pipeline for a long time, which will cause poor water flow in the pipeline, and in severe cases, it will also cause blockage of the water pipe and cause accidents, which will bring a lot of loss to the factory's annual replacement of pipelines
[0003] The current descaling agent for removing scale in pipelines has complex components, low effective components, single dirt removal, and cannot remove scales that contain more impurities and complex components, and remain in the pipeline for a long time. , because the acidity is too strong, it will also cause unnecessary secondary damage to the pipeline, which seriously reduces the service life of the pipeline

Embodiment 1

[0019] In this embodiment, a pipeline descaling agent, its raw material weight component percentage is: sodium phosphate 9%, polyacrylamide 10%, polymaleic anhydride 11%, sodium dodecylbenzene sulfonate 10%, hydroxyl Ethylene acid 9%, amino trimethylene phosphonic acid 9%, acrylic acid 5%, methyl acrylate 6%, gallic acid 6%, resorcinol 5%, phloroglucinol 3%, polyepoxysuccinic acid 4%, sodium stearate 4%, lime Bordeaux mixture 5%, citric acid 1%, triethanolamine 2%. After the raw materials are prepared according to the proportion, they are stirred and mixed at 60° C., and the prepared reagent is applied to the sewage pipeline with a pH value of 11 to treat scale.

Embodiment 2

[0021] In this embodiment, a pipeline descaling agent, its raw material weight component percentage is: sodium phosphate sodium phosphate 11%, polyacrylamide 12%, polymaleic anhydride 13%, sodium dodecylbenzene sulfonate 8% , hydroxyethylene acid 8%, amino trimethylene phosphonic acid 8%, acrylic acid 4%, methyl acrylate 6%, gallic acid 7%, resorcinol 6%, phloroglucinol 3%, polyepoxy Succinic Acid 3%, Sodium Stearate 3%, Lime Bordeaux Mixture 3%, Lauryl Dimethyl Ammonium Chloride 2%, Sodium Lauryl Sulfate 1%, Citric Acid 1%, Triethanolamine 1%. After the raw materials are prepared according to the proportion, they are stirred and mixed at 60° C., and the prepared reagent is applied to sewage pipes with a pH value of 7 to treat scale.

Embodiment 3

[0023] In this embodiment, a pipeline descaling agent, its raw material percentage by weight is: sodium phosphate 11%, polyacrylamide 14%, polymaleic anhydride 13%, sodium dodecylbenzene sulfonate 9%, hydroxyl Ethylene acid 9%, amino trimethylene phosphonic acid 9%, methyl acrylate 7%, gallic acid 4%, resorcinol 4%, phloroglucinol 3%, polyepoxysuccinic acid 4%, hard Sodium fatty acid 4%, lauryl dimethyl ammonium chloride 6%, sodium lauryl sulfate 1%, citric acid 2%. After the raw materials are prepared according to the proportion, they are stirred and mixed at 60° C., and the prepared reagent is applied to sewage pipes with a pH value of 9 to treat scale.

Abstract

The invention relates to a pipeline anti-scaling agent and a preparation method thereof. The pipeline anti-scaling agent comprises the following components by weight percent: 5 to 15 percent of sodium phosphate, 6 to 17 percent of polyacrylamide, 7 to 15 percent of polymaleic anhydride, 4 to 11 percent of sodium dodecyl benzene sulfonate, 7 to 11 percent of hydroxyethylidene acid, 6 to 11 percent of amino trimethylene phosphonic acid, 5 to 13 percent of acrylic acid copolymer copolymer, 4 to 8 percent of gallic acid, 7 to 11 percent of phenolic derivative, 3 to 5 percent of polyepoxysuccinic acid, 2 to 6 percent of sodium stearate, 3 to 7 percent of sterilizing agent and 2 to 4 percent of rust remover. By adopting the pipeline anti-scaling agent, scale remaining in the pipeline for a long time can be effectively removed, the scale removal capacity is high, secondary harm to the pipeline is avoided, and the pipeline can have a scale-preventing function.

Description

technical field [0001] The invention relates to the field of sewage treatment agents, in particular to a pipeline scale remover and a preparation method thereof. Background technique [0002] With the development of industrialization and informatization, the discharge of waste gas and waste water produced in various industries is becoming more and more serious, and the composition of industrially produced waste water is very complex, especially those with high alkalinity, which are easy to form in the pipeline when the workshop is discharged. Scale has complex components, and long-term formation in the pipeline will cause poor water flow in the pipeline, and in severe cases, it will also cause blockage of the water pipe and cause accidents, which will bring a lot of loss to the factory's annual replacement of pipelines. [0003] The current descaling agent for removing scale in pipelines has complex components, low effective components, single dirt removal, and cannot remove...
