Description

Technical Field

[0001] The invention relates to the technical field of a yellow spot remover for a rail passenger car paint surface, in particular to a method for preparing the yellow spot remover for a rail passenger car paint surface. Background Art

[0002] In the modern transportation system, rail passenger cars are high-speed and efficient means of transportation, carrying a large number of passengers and goods, shuttling between major cities. However, as the vehicle runs at high speed, its external body will inevitably adhere to a large amount of dust, clay, protein, and carbon powder produced by wheel-rail friction. These stains will gradually form mixed dirt that is difficult to clean over a long period of time, which will have a serious impact on the appearance and performance of the vehicle.

[0003] Specifically, inorganic stains such as dust and clay will adhere to the surface of the vehicle body, forming a thick layer of dirt, which not only affects the appearance of the vehicle, but also increases the vehicle's operating energy consumption. Because the existence of the dirt layer increases the friction resistance between the vehicle body and the air, the vehicle needs to consume more energy to maintain the same operating speed.

[0004] At the same time, organic stains such as protein can also corrode the car body. These stains are prone to breed bacteria, mold and other microorganisms in a humid or high temperature environment, corroding the paint layer of the car body, causing the gloss and hardness of the paint to gradually decrease. Over time, the paint layer of the car body is prone to fading and peeling, seriously affecting the appearance and service life of the vehicle.

[0005] In addition, stains such as carbon powder generated by wheel-rail friction are also a problem that cannot be ignored. Carbon powder stains are not only difficult to clean, but also form a hard protective layer on the surface of the vehicle body, making it easier for other stains to adhere and accumulate. The presence of this mixed dirt not only further increases the difficulty of cleaning, but also causes more serious erosion and damage to the paint layer of the vehicle body. Summary of the invention

[0006] (I) Purpose of the invention

[0007] In view of this, the purpose of the present invention is to provide a method for preparing a yellow spot remover for railway passenger car paint, thereby solving the problems raised in the above background.

[0008] (II) Technical solution

[0009] A method for preparing a yellow spot remover for railway passenger car paint, the method comprising the following steps:

[0010] 1). Prepare deep penetrant, stripping agent, emulsifier, high-activity enzyme and β-complex alkali as compound ingredients, and ensure that the remover does not contain nitrogen and phosphorus;

[0011] 2) Mix the above ingredients in a certain proportion and stir thoroughly until a uniform colorless, transparent to light yellow liquid is formed;

[0012] 3). Adjust the pH value of the mixed solution to the weak alkaline range to meet environmental protection requirements;

[0013] 4) Conduct quality inspection on the remover to ensure that it has the performance of efficient yellow spot removal, no residue, dust resistance, and bright and clean appearance.

[0014] Preferably, the remover has a wide range of applicability and high efficiency in removing yellow spots on rail passenger car paint and other materials (such as steel, glass, plastic, rubber), which means that no matter what material surface the yellow spot problem is, the remover can provide an effective solution. Its high efficiency in removing yellow spots is not only reflected in the speed of removing yellow spots, but also in the clean and residue-free surface after removal, which provides great convenience for subsequent maintenance and care.

[0015] Preferably, the remover is used in the form of stock solution or diluted with water. Liquids A and B need to be mixed, and the storage time after mixing must not exceed 4 hours to ensure the best effect of the remover. This feature makes the remover more convenient in actual operation and also improves work efficiency.

[0016] Preferably, the remover can be used at room temperature. If the macular degeneration is severe, it is recommended to heat it to 50-60 degrees before use to improve the removal effect. This allows the remover to provide the best solution when dealing with macular degeneration problems of different difficulty levels.

[0017] Preferably, the method of using the remover includes flushing with a spray gun or scrubbing manually. After cleaning until the dirt is completely removed, rinse thoroughly with clean water and let it air dry naturally before entering the next process. This simple and convenient method of use not only reduces the difficulty of operation, but also improves work efficiency.

[0018] Preferably, the remover avoids the high corrosiveness of strong acid cleaning agents, and systematically addresses the various components of yellow spots, thereby effectively protecting the gloss and hardness of the rail coach paint surface. The remover not only avoids high corrosiveness, but also systematically addresses the various components of yellow spots. This means that it is not just a simple physical removal of stains, but by analyzing the chemical composition of yellow spots and using targeted chemical methods, the stains are fundamentally broken down to ensure a more thorough cleaning effect, and the gloss and hardness of the rail coach paint surface can be protected to the maximum extent during the cleaning process. This is crucial to maintaining the beauty of the vehicle and extending its service life. Maintaining gloss and hardness not only enhances the overall image of the vehicle, but also reduces the problem of paint aging caused by frequent cleaning.

[0019] Preferably, the remover is non-corrosive, non-flammable, nitrogen-free, and phosphorus-free, and meets environmental protection requirements. It will not pollute the environment or cause health hazards to operators during use.

[0020] It can be seen from the above technical solutions that this application has the following beneficial effects:

[0021] 1. The remover in the invention is compounded with environmentally friendly ingredients such as deep penetrant, stripper, emulsifier, high-activity enzyme and β-complex alkali to ensure that it does not contain nitrogen and phosphorus and meets modern environmental protection requirements. It can not only efficiently remove yellow spots on the paint surface of railway passenger cars and other materials (such as steel, glass, plastic, rubber), but also has the characteristics of no residue and dust prevention. Compared with traditional strong acid cleaning agents, this remover avoids high corrosiveness, effectively protects the gloss and hardness of the paint surface, and does not produce harmful substances during use, which is environmentally friendly.

[0022] 2. The remover in the invention has a wide range of applicability. It is not only suitable for the paint surface of railway passenger cars, but can also effectively remove yellow spots on many other materials to meet a variety of cleaning needs. When using, you can choose to use the original liquid or add water according to your needs, and the placement time of the A and B liquids after proportioning should not exceed 4 hours to ensure the best effect of the remover. In addition, the remover can be used at room temperature. If the yellow spots are severe, the effect will be better after heating to 50-60 degrees. The method of use is simple, including flushing with a spray gun or manual scrubbing. After cleaning until the dirt is completely removed, rinse thoroughly with clean water and let it dry naturally before entering the next process, which greatly improves the cleaning efficiency and convenience.

[0023] 3. The remover in this invention takes safety and reliability into full consideration during the research and development process, ensuring that the product is non-corrosive, non-flammable, nitrogen-free, and phosphorus-free, and meets strict environmental standards. During use, it will not cause harm to operators and the environment, ensuring the safe conduct of cleaning work. In addition, the remover systematically addresses the various components of yellow spots, effectively avoiding the paint damage and environmental pollution problems that may be caused by traditional cleaners, and providing safe and reliable cleaning guarantees for the long-term maintenance and care of rail vehicles.
