In winter, when the road is covered with snow or ice, many places will use snow dissolving agents to speed up the melting of snow and ensure the smooth and safe flow of the road. However, what are the effects of snow dissolving agents on car chassis?This is a matter of concern because the chassis of a car is an important part of a car that directly affects the performance and life of the car. This article will analyze the effects of snow dissolving agent on automobile chassis from the aspects of composition, function, impact on automobile chassis and protective measures.
A snow dissolving agent is a substance that can lower the melting point of snow or ice, making it easier to melt. Depending on the composition, the snow dissolving agent can be divided into the following types:
Salt snow dissolving agent: This is the most common snow dissolving agent, the main ingredients are sodium chloride, magnesium chloride, calcium chloride, etc., usually used in the form of solid particles or liquid solutions, with the advantages of low quality, good effect, easy to use, etc., but there are also disadvantages, such as the environment, plants, animals, human body, automobiles, etc. have a certain corrosiveness, which will increase the salinity of the water body, affect the water quality and ecological balance, etc. Organic snow dissolving agent: this is a relatively new snow dissolving agent, the main components are glycerin, ethylene glycol, methanol, ethanol, etc., usually used in the form of liquid solution, with less corrosiveness to the environment, plants, animals, human body, automobiles, etc., will not increase the salinity of the water body, does not affect the water quality and ecological balance and other advantages, but also has disadvantages, such as high quality, poor effect, large use, volatile, etc. Composite snow dissolving agent: this is a combination of salt snow dissolving agent and organic snow dissolving agent advantages of snow dissolving agent, the main component is a mixture of salt snow dissolving agent and organic snow dissolving agent, usually used in the form of solid particles or liquid solution, with the advantages of moderate, good effect, small amount of use, less corrosiveness to the environment, plants, animals, human body, automobiles, etc., is the ideal snow dissolving agent at present. The main function of the snow dissolving agent is to reduce the melting point of snow or ice on the ice and snow pavement, making it easier to melt, thereby reducing the snow or ice on the pavement, improving the friction coefficient of the pavement, preventing the vehicle from skidding or losing control, and ensuring the smoothness and safety of the road. The principle of snow dissolving agent is to use the solubility of solute with the change of temperature, when the solute is dissolved in water, it will reduce the freezing point of water, so that the water remains liquid at a temperature below 0, so as to prevent the freezing of water, or make the water that has been frozen remelt.
The chassis of the car is the basic structure of the car, which carries various parts of the car, such as the engine, gearbox, suspension system, braking system, steering system, etc., and also bears the weight of the car and the impact of driving. The material of the automobile chassis is generally metal or alloy, which has a certain strength and wear resistance, but also has a certain degree of corrosion. The impact of snow dissolving agent on automobile chassis is mainly in the following aspects:
Corrosion: The salts or organic substances in the snow dissolving agent will react chemically with the metal or alloy of the automobile chassis to produce some corrosive substances, such as chlorides, oxides, etc., which will adhere to the surface of the automobile chassis to form a layer of corrosion, making the material of the automobile chassis thinner, weaker and brittle, reducing the strength and wear resistance of the automobile chassis, and shortening the life of the automobile chassis. Especially after the snow melts, the snow dissolving agent will penetrate into the cracks or cracks of the automobile chassis, accelerating the corrosion process of the automobile chassis. Electrochemical action: The salts or organic matter in the snow dissolving agent will enhance the conductivity of water and form an electrolyte. When different parts of the automobile chassis or different materials come into contact with this electrolyte, a galvanic battery will be formed, and an electric current will be generated, so that one part of the automobile chassis will become the anode, and the other part will become the cathode, the anode will undergo oxidation reaction, and the cathode will undergo a reduction reaction, so that one part of the automobile chassis will lose electrons, and the other part will gain electrons, resulting in uneven corrosion of the automobile chassis, which is often called electrolytic corrosion. Physical effect: The particles or droplets in the snow dissolving agent will constantly hit the surface of the automobile chassis with the driving of the car, causing wear or scratching of the automobile chassis, making the surface of the automobile chassis rough or uneven, affecting the aesthetics and air tightness of the automobile chassis, and also making the corrosion layer of the automobile chassis easier to fall off, exposing new metal or alloy surfaces, and increasing the corrosion area and degree of the automobile chassis.
In order to reduce or avoid the impact of snow dissolving agent on the chassis of the car, the car owner can take regular car washing: in winter, the car owner should wash the car regularly, especially after driving on the road surface with snow dissolving agent, the car should be washed in time to remove the snow melting agent and other debris attached to the car chassis, and prevent the long-term corrosion of the snow melting agent on the automobile chassis.
