Description

Technical Field

[0001] The invention relates to the technical field of detergents, in particular to a pipe cleaning detergent capable of removing red rust. Background Art

[0002] In many industrial fields and in the water supply and drainage systems of daily life, pipes play a vital role in transportation. However, as time goes by, the inner wall of the pipe is very easy to rust, and red rust is particularly common. This not only affects the water delivery efficiency of the pipe, resulting in increased water flow resistance and reduced flow, but also may pollute the transported medium, such as deteriorating water quality, rusty odor, and even causing secondary pollution problems such as microbial growth.

[0003] Traditional pipeline cleaning methods have many limitations. For example, physical cleaning methods such as high-pressure water washing can wash away some loose rust layers, but they are not effective in removing stubborn red rust, and are likely to cause certain damage to the inner wall of the pipeline, shortening the service life of the pipeline; chemical pickling methods, although using strong acid to quickly dissolve rust, are highly corrosive and can easily corrode the material of the pipeline, especially for some metal pipelines, which may cause the pipe wall to become thinner and affect the structural strength. There is also the problem of subsequent waste liquid treatment, which can cause serious pollution to the environment if not handled properly.

[0004] Therefore, there is an urgent need for an environmentally friendly cleaning agent that can not only effectively remove red rust, but also protect the pipe material, and the cleaning agent capable of removing red rust of the present invention comes into being. Summary of the invention

[0005] In order to solve the above-mentioned problems, the present invention provides a pipe cleaning detergent capable of removing red rust.

[0006] In order to solve the above technical problems, the technical solution proposed by the present invention is: a pipe cleaning detergent capable of removing red rust, the core components and weight proportions of which are as follows:

[0007] Abrasive particles: 3.0-30.0%;

[0008] Surfactant: 5.0-45.0%, which can be composed of at least one of the following combinations:

[0009] Anionic surfactants: sodium dodecyl sulfate, sodium alkylbenzene sulfonate;

[0010] Non-ionic surfactants: fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether;

[0011] Zwitterionic surfactant: cocamidopropyl betaine;

[0012] Thickener: 1.0-10.0%;

[0013] Humectant: 2.0-15.0%;

[0014] Fungicide: 0.1-5.0%;

[0015] The remainder is water.

[0016] Preferably, the abrasive particles can be selected from at least one of quartz sand, corundum powder, silicon carbide powder, glass beads, and artificial diamond powder, and the weight proportion is more preferably 8.0-20.0%.

[0017] Preferably, the weight percentage of the surfactant is more preferably 15.0-35.0%.

[0018] Preferably, the thickener can be selected from at least one of sodium carboxymethyl cellulose, hydroxyethyl cellulose, xanthan gum, guar gum and bentonite, and the weight proportion is more preferably 3.0-7.0%.

[0019] Preferably, the moisturizing agent can be selected from at least one of glycerin, propylene glycol, sorbitol and polyethylene glycol, and the weight proportion is more preferably 5.0-12.0%.

[0020] Preferably, the bactericide can be selected from at least one of benzalkonium chloride, triclosan, chlorine dioxide, quaternary ammonium salt bactericides, etc., and the weight proportion is more preferably 0.5-3.0%.

[0021] Preferably, the solution is weakly acidic to neutral, with a pH value ranging from 5.0 to 7.5.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] Highly efficient rust removal: This pipe cleaning detergent has an excellent effect on removing red rust in pipes. In its unique formula, abrasive particles such as quartz sand and corundum powder can scrape the stubborn rust layer with physical friction, laying the foundation for chemical rust removal; surfactants can reduce surface tension, emulsify and disperse rust, and separate it from the pipe wall. As shown in the embodiment, the red rust removal rate for cleaning pipes of different materials and rust layer levels is more than 85%, and the highest is 92%. It can quickly restore the water delivery efficiency of the pipeline, ensure the purity of the medium, and reduce the risk of rust odor and microbial growth.

[0024] Protected pipe material: weakly acidic to neutral (pH value 5.0-7.5), cleverly balancing the needs of rust removal and pipe protection. It has the ability to dissolve red rust and prevent strong acid from corroding common metal and plastic pipes. For steel pipes, copper pipes, PVC, PPR pipes, etc., there is no obvious damage to the pipe wall after cleaning. Copper pipes can also improve corrosion resistance, extend the service life of pipes, reduce the cost of frequent pipe replacement, and escort the stable operation of industrial and domestic water supply and drainage systems.

[0025] Environmentally friendly and easy to operate: The composition design takes environmental protection into consideration, abandons traditional pickling strong acid, and reduces waste liquid pollution. The preparation process is simple, and each embodiment can be made by mixing and stirring according to the steps. It is easy to dilute during use, and the cleaning liquid is prepared in different proportions. The flow rate and time are easy to control. Ordinary operators can get started after simple training. At the same time, the bactericide inhibits pipeline microorganisms, prevents secondary pollution, ensures long-term cleaning, conforms to the concept of sustainable development, and is suitable for cleaning needs in multiple scenarios.
