Description

Technical Field

[0001] This invention relates to the field of cleaning agent technology, specifically to a powerful toilet cleaner that removes dirt and odors without damaging the glaze, and its preparation method. Background Technology

[0002] Toilet cleaner, a common cleaning product, is widely used to remove dirt and odors from bathrooms. However, most viscous toilet cleaners on the market are made with hydrochloric acid, an acidic thickener (cellulose), and a small amount of surfactant. This formula can easily damage the glaze and is not easy to disperse, thus affecting its odor-removing and cleaning power.

[0003] In addition, most water-based, non-sticky toilet cleaners on the market are basically made of industrial waste hydrochloric acid + water or industrial waste hydrochloric acid + water + a small amount of surfactant. This kind of formula is particularly damaging to the glaze and has a pungent smell.

[0004] Most leading toilet cleaner brands use the first type of formula mentioned above. While this meets cleaning needs to some extent, it still causes significant damage to the glaze and produces a pungent odor. Furthermore, the large amount of fumes generated during production has a considerable environmental impact. Therefore, developing a toilet cleaner that effectively removes stains and odors while minimizing damage to the glaze and being environmentally friendly and safe has become an urgent technical challenge. Summary of the Invention

[0005] To address the aforementioned issues, a powerful toilet cleaner that does not damage the glaze and effectively removes stains and odors is provided, along with its preparation method. This toilet cleaner, through optimized formulation and production process, overcomes the problems of significant damage to the glaze, noticeable pungent odor, and poor environmental friendliness in the existing technology, while possessing both high-efficiency stain removal and excellent odor-removing effects.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a powerful toilet cleaner that does not damage the glaze and effectively removes dirt and odors, characterized in that it comprises the following raw materials in weight percentage: 20% hydrochloric acid, 3.5% sodium dodecylbenzenesulfonate, 0.2% fluorocarbon surfactant (nonionic), and 0.1% colorant; the toilet cleaner is prepared by mixing in a specific order and under specific process conditions.

[0007] Preferably, the method of introducing hydrochloric acid includes the following steps: hydrochloric acid is pumped through a pipeline to a 500L weighing tank for later use, and then added in batches to a mixing tank; first, water is added to the mixing tank to 50%, then sodium dodecylbenzenesulfonate is slowly added and stirred for 15 minutes. After observing that the material is completely dissolved, the weighed hydrochloric acid is pumped through a pipeline to a plastic mixing tank and stirred for 10 minutes to ensure that the material is fully mixed.

[0008] Preferably, the preparation and addition of sodium dodecylbenzenesulfonate includes the following steps: take sodium dodecylbenzenesulfonate, slowly add it to a stirring tank, and stir for 15 minutes to ensure complete dissolution; its function is to reduce the corrosiveness of hydrochloric acid to the glaze through intermolecular interactions and enhance the dispersibility and stability of the product.

[0009] Preferably, the fluorocarbon surfactant is introduced by the following steps: after hydrochloric acid and sodium dodecylbenzenesulfonate are thoroughly mixed, fluorocarbon surfactant and colorant are added in sequence and stirred for 10 minutes; the fluorocarbon surfactant prevents the peeled dirt from re-attaching through charge repulsion and steric hindrance effects, and works with hydrochloric acid to accelerate penetration into the scale and rust.

[0010] Preferably, the method of adding the colorant includes the following steps: after adding the fluorocarbon surfactant, add an appropriate amount of acidic blue pigment, stir for 10 minutes, then turn off the stirring, add water to the production quantity required by the instruction card; during this process, the stirring tank cover should be covered and the external hygiene should be cleaned, then the stirring should be turned on again for 5 minutes and then turned off, and after the material has settled, observe whether the appearance and odor are normal.

[0011] The preparation method of toilet cleaner includes the following steps: S1: Thoroughly clean the mixing tank and add water to 50%; S2: According to the production requirements, the weight of hydrochloric acid is pumped through a pipeline to a 500L weighing tank for later use; S3: Slowly add sodium dodecylbenzenesulfonate to the mixing tank, stir for 15 minutes, and proceed to the next step after observing that the material is completely dissolved; S4: Pump the weighed hydrochloric acid through a pipeline to a plastic mixing tank, stir for 10 minutes, and proceed to the next step after observing that the material is completely dissolved and mixed; S5: Add fluorocarbon surfactant and colorant in sequence, stir for 10 minutes, then turn off the stirring, add water to the production quantity required by the instruction card, cover the mixing tank, clean the external sanitation, turn on the stirring for 5 minutes, then turn off the stirring, wait for the material to settle, and observe whether the appearance and odor are normal; S6: Notify the quality inspector to retest; S7: Place in a storage tank and let it stand in preparation for filling.

[0012] Preferably, the cleaning step of the mixing tank includes thoroughly cleaning the inner wall and bottom of the mixing tank to ensure that no residual impurities affect the stability of subsequent processes.

[0013] Preferably, during the process of the hydrochloric acid being pumped through a pipeline to a 500L weighing tank, a corrosion-resistant hydrochloric acid delivery pipeline is used, and the flow rate is controlled by a valve to ensure that the amount of hydrochloric acid added accurately meets the formula requirements.

[0014] Preferably, the amount of fluorocarbon surfactant added to the active area of ​​the fluorocarbon surfactant is strictly controlled according to the formula ratio. Excessive addition may cause instability of the system, while insufficient addition will prevent it from playing its due role.

[0015] Preferably, the design of the waste gas treatment system includes setting an air inlet for a waste gas treatment device at the opening of the mixing tank to collect and treat the smoke generated during the production process. The treated waste gas must meet national environmental protection standards before it can be discharged.

[0016] Compared with the prior art, the beneficial effects of the present invention are: a powerful toilet cleaner that does not damage the glaze and removes dirt and odors, and its preparation method:

[0017] This application discloses a powerful, non-damaging toilet cleaner that effectively removes stains and odors, along with its preparation method. Through scientific formulation and optimized processes, it solves the problems of existing technologies, such as easy damage to the glaze, a strong pungent odor, and poor environmental friendliness in the production process. The introduction of sodium dodecylbenzenesulfonate and fluorocarbon surfactants into the formula significantly reduces the corrosiveness of strong acids, enhances the product's stability and dispersibility, and avoids the dispersibility problem caused by cellulose thickeners in traditional formulas. Simultaneously, the fluorocarbon surfactants prevent stains from becoming sticky again through charge repulsion and steric hindrance effects, and synergistically accelerate the dissolution of scale and rust stains with hydrochloric acid, thereby improving cleaning efficiency.

[0018] Furthermore, the production process generates very little smoke, which is easily treated through the exhaust gas system, reducing environmental impact. Long-term use of this product can reduce the frequency of using other odor-masking methods, thereby reducing secondary pollution.

[0019] In summary, this invention demonstrates significant advantages in terms of environmental friendliness, safety, and functionality, providing an innovative solution for the toilet cleaner industry. Attached Figure Description

[0020] Figure 1 This is a process flow diagram of the present invention. Detailed Implementation

[0021] The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides a technical solution: a powerful toilet cleaner that does not damage the glaze and removes dirt and odors, and its preparation method: comprising the following raw materials by weight percentage: 20% hydrochloric acid, 3.5% sodium dodecylbenzenesulfonate, 0.2% fluorocarbon surfactant (nonionic), and 0.1% colorant.

[0023] The mixing tank is the core equipment in the entire process, used to mix and homogenize the raw materials. First, the mixing tank is thoroughly cleaned to ensure no residual impurities affect the stability of subsequent processes. After cleaning, water is added to 50% of the tank's capacity; this step provides a suitable environment for the dissolution and mixing of the raw materials. Then, 20% hydrochloric acid is transferred to a 500L weighing container via a hydrochloric acid delivery pipeline for later use. This pipeline is designed to be corrosion-resistant to prevent leakage or contamination caused by hydrochloric acid erosion. In actual operation, the flow rate between the hydrochloric acid delivery pipeline and the mixing tank is controlled by a valve to ensure that the amount of hydrochloric acid added accurately meets the formulation requirements.

[0024] While preparing the hydrochloric acid, slowly add 3.5% sodium dodecylbenzenesulfonate to the sodium dodecylbenzenesulfonate dissolution zone in the mixing tank. In this zone, the sodium dodecylbenzenesulfonate comes into full contact with water and gradually dissolves under mechanical stirring. The stirring time is set to 15 minutes, during which time the material needs to be observed to ensure complete dissolution. After dissolution, the weighed hydrochloric acid is transferred to the plastic mixing tank through the hydrochloric acid delivery pipe, and stirring continues for 10 minutes. The mixing order of hydrochloric acid and sodium dodecylbenzenesulfonate is crucial in this process, as the presence of sodium dodecylbenzenesulfonate effectively reduces the volatilization of hydrogen chloride fumes, while also acting as a corrosion inhibitor and thickener. The mixture in the mixing tank forms a preliminary stable system at this stage, laying the foundation for the subsequent addition of raw materials.

[0025] Next, after thoroughly mixing hydrochloric acid and sodium dodecylbenzenesulfonate, fluorocarbon surfactants and colorants are added sequentially. The main function of adding fluorocarbon surfactants is to prevent the detached dirt from re-adhering to the glaze surface through charge repulsion and steric hindrance effects.

[0026] In practice, the amount of fluorocarbon surfactant added must be strictly controlled according to the formula ratio. Excessive amounts may lead to system instability, while insufficient amounts will prevent it from functioning properly. After adding the fluorocarbon surfactant, continue stirring for 10 minutes to ensure it is evenly dispersed throughout the system. Then, add an appropriate amount of acidic blue pigment as a colorant, stir for 10 minutes, and then turn off the stirring device. At this point, add water to the liquid in the stirring tank to the production quantity required by the instruction card, cover the stirring tank, and clean the exterior. Restart stirring for 5 minutes, then turn it off. After the material has settled, observe whether the appearance and odor are normal. This series of operations ensures the uniformity and stability of the product, and the color change visually reflects the product's quality status.

[0027] The hydrochloric acid in toilet cleaner effectively penetrates limescale and rust, reacting chemically to form soluble substances and thus achieving a cleaning effect. Fluorocarbon surfactants play a dual role in this process: firstly, they prevent re-adhesion of dirt through charge repulsion; secondly, they enhance the penetrating power of hydrochloric acid on limescale and rust through steric hindrance. Furthermore, the presence of sodium dodecylbenzenesulfonate further reduces the corrosiveness of hydrochloric acid to the glaze, while enhancing the product's dispersibility and stability. This multi-component synergistic design allows the toilet cleaner to effectively remove dirt while avoiding damage to the glaze.

[0028] In practical applications, toilet cleaner is used as follows: Pour an appropriate amount of product onto the inner wall of the toilet bowl, ensuring it evenly covers the glaze. Due to the presence of fluorocarbon surfactants, the cleaner quickly penetrates limescale and rust, breaking them down into soluble substances through a chemical reaction. Simultaneously, the steric hindrance effect of the fluorocarbon surfactants effectively prevents the decomposed dirt from re-adhering to the glaze, thus achieving a highly efficient cleaning effect. After use, simply rinse with water to restore the glaze's smoothness. The entire process requires no additional wiping or other auxiliary tools, simplifying the cleaning process and improving efficiency.

[0029] The design of the waste gas treatment system also requires close attention during the production process. Due to the high volatility of hydrochloric acid, a small amount of hydrogen chloride fumes may be generated during production. Therefore, the workshop needs to be equipped with a high-efficiency waste gas treatment device to collect and treat the fumes generated during production. The air inlet of the waste gas treatment system should be located near the opening of the mixing tank to ensure that the fumes can be extracted and treated in a timely manner. The treated waste gas must meet national environmental protection standards before it can be discharged, thereby reducing its impact on the environment.

[0030] In terms of quality control, each batch of products undergoes rigorous testing to ensure its performance meets requirements. Quality inspectors retest the appearance, odor, pH value, and detergency of the finished products; only products that pass all tests are allowed to proceed to the filling stage. Before filling, storage tanks must be kept clean and regularly disinfected to prevent microbial contamination. After filling, the product must be left to stand in a designated area for a period of time to further observe its stability. Finally, qualified products are packaged and released to the market.

[0031] The above embodiments describe in detail the complete process flow of the present invention from raw material preparation to finished product filling, as well as the mechanism of action of toilet cleaner in practical applications. Through scientific formulation and optimized process, the present invention solves the problems of easy damage to the glaze, obvious pungent odor, and poor environmental protection in the production process of the prior art, providing an innovative solution for the toilet cleaner industry.

[0032] To enable those skilled in the art to fully understand and implement this invention, the specific implementation principle of this invention will be further explained below in conjunction with a specific application scenario.

[0033] First, after thoroughly cleaning the mixing tank, add water to 50% of its capacity to ensure that subsequent raw materials can dissolve and mix in a suitable environment. Then, hydrochloric acid is transferred to a 500L weighing container via a hydrochloric acid delivery pipeline for later use. During this process, the hydrochloric acid delivery pipeline must be designed with good corrosion resistance, and the flow rate must be precisely controlled by valves to avoid formulation deviations due to over- or under-filling. The key to this step is ensuring a stable delivery of hydrochloric acid, preventing leaks caused by pipeline corrosion, and providing a precise basis for the raw material proportions in subsequent processes.

[0034] Next, sodium dodecylbenzenesulfonate is slowly added to the water in the mixing tank. The sodium dodecylbenzenesulfonate gradually dissolves in the water under mechanical stirring for 15 minutes. The core principle of this process is that the hydrophilic groups in the sodium dodecylbenzenesulfonate molecule form hydrogen bonds with water molecules, thus achieving uniform dispersion. After dissolution, the weighed hydrochloric acid is transferred to the plastic mixing tank via a hydrochloric acid delivery pipeline, and stirring continues for 10 minutes. In this step, the presence of sodium dodecylbenzenesulfonate effectively reduces the volatilization of hydrogen chloride fumes and, through its corrosion-inhibiting effect, reduces the corrosiveness of hydrochloric acid to the equipment and glaze. Furthermore, sodium dodecylbenzenesulfonate enhances the stability of the mixture through intermolecular interactions, laying the foundation for the subsequent addition of raw materials.

[0035] Subsequently, fluorocarbon surfactants and colorants are added sequentially. The main function of fluorocarbon surfactants is to prevent the detached dirt from re-adhering to the glaze surface through charge repulsion and steric hindrance. In practice, the amount of fluorocarbon surfactant added must be strictly controlled according to the formula ratio; excessive amounts may lead to system instability, while insufficient amounts will fail to exert their intended effect. After adding the fluorocarbon surfactant, continue stirring for 10 minutes to ensure its uniform dispersion throughout the system. The principle behind this step is that the low surface tension of fluorocarbon surfactants allows them to quickly penetrate the microporous structure of scale and rust, preventing dirt redeposition through steric hindrance. Simultaneously, the nonionic nature of fluorocarbon surfactants reduces interference with other components, further enhancing the stability of the system.

[0036] After completing the above steps, add an appropriate amount of acidic blue pigment as a coloring agent, stir for 10 minutes, and then turn off the stirring device. At this point, add water to the liquid in the stirring tank to the production quantity required by the instruction card, cover the stirring tank, and clean the outside. Turn the stirring back on for 5 minutes, then turn it off. After the material has settled, observe whether the appearance and odor are normal. The principle of this step is to visually reflect the uniformity and stability of the product through color changes, while ensuring that the final product meets sensory quality requirements.

[0037] In practical applications, toilet cleaner is used as follows: Pour an appropriate amount of product onto the inner wall of the toilet bowl, ensuring it evenly covers the glaze. Due to the presence of fluorocarbon surfactants, the toilet cleaner can quickly penetrate limescale and rust, breaking them down into soluble substances through a chemical reaction. Specifically, the hydrochloric acid reacts with calcium carbonate (CaCO3) in the limescale to produce soluble calcium chloride (CaCl2), and reacts with iron oxide (Fe2O3) in the rust to produce soluble ferric chloride (FeCl3). Simultaneously, the steric hindrance effect of the fluorocarbon surfactants effectively prevents the decomposed dirt from re-adhering to the glaze, thus achieving a highly efficient cleaning effect. After use, simply rinse with water to restore the glaze's smoothness. The entire process requires no additional wiping or other auxiliary tools, significantly simplifying the cleaning process and improving efficiency.

[0038] The design of the waste gas treatment system also requires close attention during the production process. Due to the high volatility of hydrochloric acid, a small amount of hydrogen chloride fumes may be generated during production. Therefore, the workshop needs to be equipped with a high-efficiency waste gas treatment device to collect and treat the fumes generated during production. The air inlet of the waste gas treatment system should be close to the opening of the mixing tank to ensure that the fumes can be extracted and treated in a timely manner. The treated waste gas must meet national environmental protection standards before it can be discharged, thereby reducing its impact on the environment. The principle of this step is to remove harmful components from the waste gas through physical adsorption and chemical neutralization, ensuring that the production process meets environmental protection requirements.

[0039] In terms of quality control, each batch of products undergoes rigorous testing to ensure its performance meets requirements. Quality inspectors retest the appearance, odor, pH value, and detergency of the finished product; only products meeting all criteria are allowed to proceed to the filling stage. Before filling, storage tanks must be kept clean and regularly disinfected to prevent microbial contamination. After filling, the product must be left to stand in a designated area for a period of time to further observe its stability. Finally, qualified products are packaged and released to the market. The principle behind this step is to ensure the safety and functionality of the product through multi-dimensional quality testing, while verifying its long-term stability through observation.

[0040] In summary, this invention, through scientific formulation and optimized process, solves the problems of easy damage to the glaze, obvious pungent odor, and poor environmental friendliness in the production process of existing technologies, providing an innovative solution for the toilet cleaner industry.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
