What Are the Functions of Car Cleaning Agents?

[SanDaniel]

Here are the functions of car cleaning agents: 1. Wetting effect: After the cleaning agent comes into contact with the dirt particles on the car's surface, the strong wetting force of the cleaning solution allows the surface of the object being cleaned to be easily wetted, promoting full contact between the two. The surface of the dirt particles and the tiny gaps within the dirt aggregates can be deeply wetted, thereby weakening and loosening the bond between the dirt and the cleaned surface. 2. Adsorption effect: The inorganic ions formed by the electrolytes in the cleaning agent bind with the dirt particles, altering the electrostatic attraction of the dirt particles and preventing redeposition of dirt. When cleaning the exterior of a car, both chemical adsorption (attraction similar to chemical bonds) and physical adsorption (intermolecular attraction) occur. 3. Suspension effect: The surfactant in the cleaning agent forms a molecular layer arranged in a specific orientation on the surface of the dirt particles, further enhancing the cleaning effect. After the surfactant molecules come into contact with the dirt particles, the hydrophobic end binds with the dirt particles, while the hydrophilic end binds with water. The molecules arranged in a specific orientation around the dirt particles tightly combine the dirt particles with the surrounding aqueous solution, integrating hydrophobic substances with hydrophilic substances, causing the surface dirt to detach and then suspend in the cleaning agent. 4. Cleaning effect: Using a high-pressure water gun to wash away the dirt. Through the continuous cycle and combined action of wetting, adsorption, dissolution, suspension, and cleaning, the dirt on the car's surface can be effectively removed.
