Snow melting agent manufacturers discuss the impact of snow melting agents on vehicles

2024-01-10

The snow melting agent has slight corrosion on the chassis, but it will not immediately cause corrosion, it is an accumulation process! Therefore, it is necessary to wash the car in a timely manner after snow to reduce corrosion to the vehicle, but now environmentally friendly snow melting agents are generally used.

The corrosion of the chassis by snow melting agents is mainly reflected in the rusting of the chassis, and long-term corrosion can easily cause damage to the chassis. Generally speaking, new car chassis has a layer of protection, but it also needs to be thickened. It is recommended to armor the car's chassis to reduce the corrosion of snow on the chassis.

The corrosion of the engine and transmission is mainly reflected in the easy occurrence of scratches and paint peeling on the surface of the transmission, which reduces its service life. The solution is to install a lower guard plate for the engine, which can effectively reduce corrosion.

The corrosion of tires mainly manifests as tire oxidation and cracking, which reduces the service life of tires. The solution is to wash the car in a timely manner after the snow melts, clean the tires and chassis with clean water, and reduce the corrosion of the vehicle by the snow melting agent.

The reason why salt can be used as a snow melting agent。

The main component of snow melting agent is edible salt. After the salt deicing agent is dissolved in water (snow), the freezing point is zero. For example, when sodium chloride (the main component of salt) is dissolved in water, its freezing point is -10 ℃, and calcium chloride can reach around -30 ℃ in acetic acid at -20 ℃. In addition to heat absorption, the dissolution of salt also plays a role in the low freezing point of saltwater, making it difficult to form ice cubes after dissolving salt in snowwater.

Salt is highly corrosive, and using salt alone as a snow melting agent for winter snow removal is very harmful. Nowadays, the general components of snow melting agents are salt and corrosion inhibitors, which have much less harm to roads and vegetation.

Snow melting agent, as the name suggests, refers to a medication that can lower the melting temperature of ice and snow. Snow melting agents melt the snow on the road by reducing the melting temperature of ice and snow, making it easier to clear the road. The playback effect is obvious, but it is harmful. Research has found that residues of snow melting agents can corrode roads and automotive rubber tires.

The dosage of snow melting agent is small, and the cost of use is low. Encourage the promotion of the use of environmentally friendly snow melting agents, consider providing appropriate economic subsidies, and make up for the price disadvantage of environmentally friendly snow melting agents, so that inorganic snow melting agents can be replaced by new and environmentally friendly snow melting agents with appropriate prices.

Snow melting agent (the main component of salt) is soluble in water, with a freezing point of -100 ℃. Calcium chloride can reach around -30 ℃ in acetic acid at -20 ℃. The freezing point of saltwater is lower than that of water, so it is difficult to form ice after dissolving salt in snowwater. In addition, after the snow melting agent dissolves in water, the ion concentration in the water increases, reducing the liquid vapor pressure of water, but the solid vapor pressure of ice remains unchanged. In order to reach the state of solid liquid vapor pressure in the ice water mixture, the ice melts. This principle also explains well the principle that saltwater is not prone to freezing. Simply put, snow melting agents reduce the melting point of snow, making it easier to melt.

Water is a special substance that decreases in density after freezing (usually solid density is greater than liquid density). Therefore, the greater the pressure, the lower the melting point of ice. That's why snow often melts easily when the wheels roll. After sprinkling snow melting agent on snowy roads, the snow is more likely to melt when the vehicle rolls.
