Description

Technical Field

[0001] The present invention belongs to the technical field of chemical cleaning agents, and in particular relates to a filter disc descaling agent for removing scale and paint mist attachments on equipment such as air conditioner condensers, and specifically relates to a filter disc descaling agent. Background Art

[0002] During long-term use of equipment such as air conditioners, scale and paint mist easily accumulate in parts such as the condenser. This dirt not only affects the heat exchange efficiency of the equipment and increases energy consumption, but may also cause damage to the equipment and shorten its service life.

[0003] Some of the detergents currently on the market have certain descaling effects, but may be environmentally unfriendly and unsafe to operate, for example, they contain harmful substances such as phosphorus and halogenated hydrocarbons.

[0004] Therefore, it is of great practical significance to develop a detergent that can effectively remove scale and paint mist attachments and is safe for the environment and operation. Summary of the Invention

[0005] The present invention aims to provide a filter disc descaling agent, the filter disc descaling agent model is FCH-233, which can effectively clean scale and paint mist adhesion, has the characteristics of safe operation and environmental safety, and does not contain phosphorus and halogenated hydrocarbons.

[0006] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0007] Filter disc descaling agent, the filter disc descaling agent is a mixture, consisting of the following components in percentage according to the concentration range:

[0008] Organic acid: 10-15% concentration range (wt%);

[0009] Linear organic alcohol ether: 10-15% concentration range (wt%);

[0010] Water softener: 2-6% concentration range (wt%);

[0011] Surfactant: 2-6% concentration range (wt%);

[0012] Water: 55-70% concentration range (wt%).

[0013] The organic acid is a mixture, specifically consisting of 40% of citric acid (A), 30% of oxalic acid (B), and 30% of malic acid (C).

[0014] Citric acid is an organic acid widely used in cleaning applications. It possesses excellent chelating properties, forming stable complexes with metal ions, thereby helping to remove metal salts such as calcium and magnesium from scale. It is relatively low in corrosiveness towards various metal materials and offers excellent safety.

[0015] Oxalic acid has strong acidity and has good solubility for some insoluble metal salt scales, such as rust (the main component is ferric oxide). It can show significant descaling effect at a relatively low concentration.

[0016] Malic acid is a mild organic acid with good biodegradability and is environmentally friendly. It can work synergistically with various surfactants to enhance the penetration and dispersion of detergents, helping to remove paint mist attachments.

[0017] The linear organic alcohol ether is a mixture, which consists of 50% of ethylene glycol butyl ether (A), 30% of propylene glycol methyl ether (B), and 20% of diethylene glycol monoethyl ether (C).

[0018] The surfactant is a homemade mixture, which is compounded by sodium dodecylbenzenesulfonate and fatty alcohol polyoxyethylene ether in a ratio of 2:1.

[0019] By compounding sodium dodecylbenzenesulfonate with fatty alcohol polyoxyethylene ether in a ratio of 2:1, a high-performance surfactant can be prepared. This surfactant, used in filter disc descaling agents, helps improve the detergent's ability to emulsify, disperse, and remove contaminants such as scale and paint mist. Fatty alcohol polyoxyethylene ethers exhibit excellent compatibility with the anionic surfactant sodium dodecylbenzenesulfonate, producing a synergistic effect that significantly enhances surface activity and detergency. Furthermore, fatty alcohol polyoxyethylene ethers are mildly irritating to skin and eyes and exhibit good biodegradability, meeting environmental requirements.

[0020] The filter disc descaling agent of the present invention can effectively clean scale and paint mist adhesion, especially has a significant cleaning effect on scale and paint scale on the air conditioner condenser, can improve the heat exchange efficiency of the equipment, reduce energy consumption, and extend the service life of the equipment.

[0021] The detergent is safe to operate and to the environment, does not contain harmful substances such as phosphorus and halogenated hydrocarbons, meets environmental protection requirements, and reduces potential harm to the health of operators.

[0022] The components work synergistically to effectively remove scale without causing damage such as corrosion to the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention can be further illustrated by the non-limiting examples given in the accompanying drawings;

[0024] Figure 1 This is a comparison chart before and after using the filter disc descaling agent of the present invention. DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to embodiments.

[0026] Filter disc descaling agent, the filter disc descaling agent is a mixture, consisting of the following components in percentage according to the concentration range:

[0027] Organic acid: 10-15% concentration range (wt%);

[0028] Linear organic alcohol ether: 10-15% concentration range (wt%);

[0029] Water softener: 2-6% concentration range (wt%);

[0030] Surfactant: 2-6% concentration range (wt%);

[0031] Water: 55-70% concentration range (wt%).

[0032] Preferably, the filter disc descaling agent is a mixture consisting of the following components in percentage according to the concentration range:

[0033] Organic acids: 12%;

[0034] Linear organic alcohol ether: 12%;

[0035] Water softener: 4%;

[0036] Surfactant: 4%;

[0037] Water: 68%.

[0038] The organic acid is a mixture, specifically consisting of 40% of citric acid (A), 30% of oxalic acid (B), and 30% of malic acid (C).

[0039] The working principle of organic acid mixtures is as follows: in filter disc descaling agents, the hydroxyl and carboxyl groups in the citric acid molecules can react with metal ions in scale to form water-soluble complexes, which remove scale from the filter disc surface. For example, when reacting with calcium carbonate, citric acid can chelate calcium ions, causing the calcium carbonate to gradually dissolve.

[0040] When oxalic acid reacts with rust, the oxalate ions and iron ions form a stable ferric oxalate complex, which dissolves and removes the rust. However, oxalic acid is somewhat corrosive to metals, so controlling its proportion in the formula and synergizing it with other organic acids can ensure effective descaling while minimizing damage to equipment.

[0041] The carboxyl and hydroxyl groups in the molecular structure of malic acid enable it to adsorb on the surface of dirt particles, reducing the adhesion between the dirt and the filter surface. At the same time, with the cooperation of surfactants, the dirt is more easily dispersed in the water, thereby achieving the purpose of cleaning.

[0042] The linear organic alcohol ether is a mixture, which consists of 50% of ethylene glycol butyl ether (A), 30% of propylene glycol methyl ether (B), and 20% of diethylene glycol monoethyl ether (C).

[0043] The linear organic alcohol ether mixture works as follows: As a detergent component, ethylene glycol butyl ether quickly penetrates paint mist and some oily dirt, reducing their adhesion to the filter surface and making them easier to clean. Furthermore, it helps improve the detergent's wettability on filters of different materials, allowing the detergent to be more evenly distributed across the filter surface, enhancing cleaning effectiveness.

[0044] In filter disc descaling agents, propylene glycol methyl ether works synergistically with other ingredients to improve the detergent's solubility in scale and oil, particularly for mixed soils. It also adjusts the detergent's surface tension, allowing it to spread better across the filter surface and improve cleaning efficiency.

[0045] In filter disc descaling agents, diethylene glycol monoethyl ether enhances the detergent's ability to dissolve and disperse stubborn dirt over a long period of time. For some difficult-to-clean, firmly adhered dirt, it acts on the surface for a long time, gradually breaking it down and dispersing it, thereby achieving the goal of thoroughly cleaning the filter disc.

[0046] The surfactant is a homemade mixture, which is compounded by sodium dodecylbenzenesulfonate and fatty alcohol polyoxyethylene ether in a ratio of 2:1.

[0047] The surfactant is a homemade mixture, and its preparation method comprises the following steps:

[0048] Step 1: Prepare the raw materials. Weigh 2 parts sodium dodecylbenzenesulfonate and 1 part fatty alcohol polyoxyethylene ether in proportion, accurate to 0.1g. Prepare an appropriate amount of deionized water for dissolution and dilution.

[0049] Step 2: dissolving the raw materials. After cleaning and drying the reactor, add an appropriate amount of deionized water, start stirring, set the speed to 100 rpm, slowly add the weighed sodium dodecylbenzenesulfonate, and continue stirring for 15-20 minutes to fully dissolve the sodium dodecylbenzenesulfonate in water to form a uniform solution. During this process, closely observe the dissolution to ensure that there is no caking;

[0050] Step 3: While maintaining the stirring state, slowly add the fatty alcohol polyoxyethylene ether into the reaction kettle and continue stirring for 10-15 minutes to fully mix the two surfactant raw materials to form a uniform mixed solution;

[0051] Step 4: Heat the reaction. Turn on the heating mantle and slowly raise the reaction temperature to 60-65°C at a rate of 5-8°C / minute. At this temperature, maintain a stirring speed of 200-250 rpm to allow the mixture to react for 1-1.5 hours.

[0052] Step 5: Cool the reaction. After the reaction is complete, turn off the heating jacket and allow the mixture in the reactor to cool naturally to room temperature (25°C). During the cooling process, continue stirring at a speed of 100-150 rpm to prevent stratification of the mixture.

[0053] Step 6, pH adjustment: After the mixed solution is cooled to room temperature, its pH value is tested. If the pH value does not meet the set range, an appropriate amount of dilute hydrochloric acid or sodium hydroxide solution is used for fine-tuning to bring the pH value into the set range of 6.5-7.5.

[0054] Filter descaling agent is used to remove scale and paint stains from air conditioner condensers.

[0055] Filter descaling agent can remove serious scale and paint mist attachments.

[0056] The filter descaling agent is free of phosphorus and halogenated hydrocarbons.

The organic acid is composed of 40% citric acid (A), 30% oxalic acid (B), and 30% malic acid (C). The linear organic alcohol ether is composed of 50% ethylene glycol butyl ether (A), 30% propylene glycol methyl ether (B), and 20% diethylene glycol monoethyl ether (C). The surfactant is a mixture of sodium dodecylbenzene sulfonate and fatty alcohol polyoxyethylene ether in a ratio of 2:1.

[0060] The components were added into the reactor in sequence and stirred for 15 minutes to fully mix them to obtain a filter disc descaling agent.

[0061] To remove dirt from the air conditioner condenser, the specific steps are as follows:

[0062] Dilute the filter descaling agent in water at a ratio of 1:10.

[0063] Spray the diluted detergent solution evenly on the surface of the air conditioner condenser.

[0064] After waiting for 15 minutes, rinse the condenser surface with clean water until it is clean. After testing, the scale and paint scale removal rate of the condenser surface reached more than 95%.
