Description
Technical Field
The invention relates to the technical field of cleaning agents, in particular to a water circulation system cleaning agent and a preparation method and application thereof.
Background
The water circulation system is a system widely used in various fields including industrial equipment, heating systems, cooling systems, etc. The water circulation device realizes the functions of heat exchange, energy transfer, wastewater treatment and the like by circularly conveying water. However, over time and during use, the water circulation system is subject to various contaminants such as sediment, rust, bacteria, algae, etc. These contaminants can reduce system efficiency, increase energy consumption, and may cause equipment damage and system failure.
To solve these problems, the water circulation system needs to be periodically cleaned and maintained. Existing water circulation system cleaners have been developed that are a class of chemical products specifically designed to clean and maintain water circulation systems. Existing cleaners have a number of significant advantages.
Firstly, the existing water circulation system cleaning agent adopts advanced formula and technology, and can quickly and effectively remove dirt and sediment. They have strong dissolving capacity, can thoroughly remove various types of pollutants, and resume the normal operation of the system. Compared with the traditional cleaning method, the existing cleaning agent is more efficient, and the cleaning time and the labor cost can be obviously reduced. Secondly, the existing cleaning agent pays attention to environmental protection performance. The environment-friendly, low-toxicity and easily degradable chemical components are adopted, so that the pollution to the environment is reduced. Many cleaning agents also use biodegradable formulations so that they can be handled easily after use without long-term environmental impact. Meanwhile, the existing cleaning agent is subjected to strict safety evaluation, so that no harm to equipment and operators is ensured in the using process. They do not contain irritating or corrosive components and are safer and more reliable to use. This provides a better operating environment for maintenance personnel of the water circulation system, reducing potential health risks. In addition, the existing cleaning agent has a lasting protection effect. Some cleaning agents form a protective film after cleaning, so that new dirt and sediment are prevented from being attached again, and the service life of the water circulation system is prolonged. The protective film can reduce friction and corrosion of the system and improve efficiency and stability of the system.
In addition to the advantages described above, existing water circulation system cleaners overcome some challenges. Firstly, some traditional cleaning agents contain harmful substances, which pollute the environment; secondly, corrosive or irritant substances can be generated in the use process of the cleaning agent, and potential risks are caused to equipment and operators; secondly, the cleaning agent is not as effective as expected and cannot completely remove dirt or kill microorganisms; secondly, as different types of pollutants exist in the water circulation system, it is important to select a proper cleaning agent, and cleaning agents with different components and formulas are required to be used for different pollutants so as to achieve the optimal cleaning effect; finally, the complex structure and piping layout of the water circulation system also increase the complexity of the cleaning process, requiring advanced cleaning formulations to ensure that the cleaning agent can adequately cover the entire system and ensure cleaning effectiveness and safety.
Based on this, there is a need to develop a novel water circulation system cleaning agent to solve the above problems.

The application of the cleaning agent.
In order to solve the first technical problem, the invention adopts the following technical scheme:
The cleaning agent comprises the following components:
A hydroxycarboxylic acid;
a nonionic surfactant;
Ethyl p-hydroxybenzoate;
A sodium salt;
Sulfonic acid compounds;
halogenated unsaturated aliphatic hydrocarbons;
sulfide corrosion inhibitors.
According to the embodiments of the present invention, one of the technical solutions has at least one of the following advantages or beneficial effects:
The cleaning agent disclosed by the invention is a cleaning agent which can be applied to cleaning of a water circulation system, has the advantages of environmental protection and high efficiency cleaning, and can enter and clean narrow pipelines and equipment to clean scale, grease and other dirt, so that the flow property of the water circulation system is better recovered.
In the cleaning agent, the hydroxycarboxylic acid forms a coordinate bond with the metal ion through the carboxyl oxygen atom in the carboxyl group (COOH). Such coordination bonds stabilize metal ions and prevent them from reacting with other materials, thereby reducing scale and scale formation. The carboxyl part in the hydroxycarboxylic acid can interact with the hydrophobic group in the nonionic surfactant to form a better emulsifying system, so that the decontamination effect is more remarkable, and the cleaning agent can enter and clean narrow pipelines and equipment more easily;
In the cleaning agent, a nonionic surfactant has a hydrophobic group (typically a fatty chain) and a hydrophilic group (typically a polyoxyethylene chain) in its molecular structure. This structure makes the nonionic surfactant both hydrophilic and hydrophobic. In the water circulation system cleaning agent, the hydrophobic group of the nonionic surfactant can interact with the hydrophobic substance on the surface of dirt to wrap the dirt, and the hydrophilic group interacts with water molecules to enable the dirt to be dispersed and cleaned more easily;
In the cleaning agent, the sulfonic acid compound can form a complex with calcium, magnesium and other ions in scale and dirt, so that the complex loses precipitability, and the aim of cleaning is fulfilled;
in the cleaning agent, the halogenated unsaturated aliphatic hydrocarbon has stronger detergency and can effectively dissolve grease and organic pollutants. In addition, the halogenated unsaturated aliphatic hydrocarbon can also play a role in corrosion protection, and the pipelines and equipment of the water circulation system are protected from corrosion and erosion.
According to one embodiment of the invention, the cleaning agent comprises the following components in parts by weight:
2-3 parts of hydroxycarboxylic acid;
1-2 parts of nonionic surfactant;
5-8 parts of ethyl p-hydroxybenzoate;
Sodium salt, 1-5 parts;
3-5 parts of sulfonic acid compounds;
2-5 parts of halogenated unsaturated aliphatic hydrocarbon;
2-5 parts of sulfide corrosion inhibitor.
According to one embodiment of the invention, the hydroxycarboxylic acid comprises at least one of acetic acid, citric acid, and oxalic acid. The hydroxycarboxylic acid has good chelating ability, and can form complex with calcium, magnesium and other ions in water, thereby reducing the generation and deposition of scale. This helps to remove calcium scale and other hard scale from the inner wall of the pipe, restoring the flow properties of the water circulation system; the hydroxycarboxylic acid has good solubility, and can quickly dissolve and remove dirt, sediment and oxide in the pipeline. It can form complex or dissolved matter with the dirt surface to destroy the dirt structure and make it easy to wash away.
According to an embodiment of the present invention, the nonionic surfactant includes at least one of octanol polyoxyethylene ether, octanol polyoxypropylene ether, polyoxyethylene stearyl alcohol ether, polyoxyethylene glyceryl ether, and polyoxyethylene polyoxypropylene ether. The nonionic surfactant has good permeability, can reduce the surface tension of water, so that the cleaning agent can more easily permeate and disperse dirt, and the cleaning effect is improved. In addition, nonionic surfactants are capable of dispersing the soil particles in the water, preventing them from redeposition and making them more easily rinsed away, they can encapsulate the soil particles, forming a micellar structure, suspending the soil particles in the water.
According to one embodiment of the invention, the sodium salt comprises at least one of sodium tripolyphosphate and sodium metasilicate pentahydrate.
According to one embodiment of the invention, the sulfonic acid compound comprises sulfamic acid. The amino in sulfamic acid and the hydroxyl in hydroxycarboxylic acid can form complexes with metal ions in scale and dirt, so that the precipitability of the sulfamic acid and the hydroxyl in hydroxycarboxylic acid is lost, and the aim of cleaning is achieved. Meanwhile, an amino group in sulfamic acid can form a layer of protective film with the surface of metal to prevent the metal from being corroded.
According to one embodiment of the present invention, the halogenated unsaturated aliphatic hydrocarbon includes at least one of trichloropropene and tetrachloroethylene. The halogenated unsaturated aliphatic hydrocarbon can enhance the cleaning effect together with the hydroxycarboxylic acid, reduce the surface tension cooperatively with the nonionic surfactant, promote decontamination, and provide protection to the metal surface together with the sulfide corrosion inhibitor.
According to one embodiment of the invention, the sulfide corrosion inhibitor includes at least one of diphenyl disulfide, benzimidazole sulfate, and diethyldithiosulfate. The sulfide corrosion inhibitor can chemically react with the metal surface of the water circulation system to form a protective compound film, and the film can isolate the contact between the metal and an external medium and has an anti-corrosion effect. In addition, the sulfide corrosion inhibitor can reduce the surface tension in cooperation with the nonionic surfactant, and the cleaning effect is improved.
In order to solve the second technical problem, the invention adopts the following technical scheme:
A method of preparing the cleaning agent comprising the steps of:
Mixing hydroxycarboxylic acid, a nonionic surfactant, ethyl p-hydroxybenzoate, sodium salt, a sulfonic acid compound, halogenated unsaturated aliphatic hydrocarbon and a sulfide corrosion inhibitor, heating, and cooling to obtain the cleaning agent.
