Since the water temperature in the water tank is always maintained at a high temperature, the hydrocarbons in the water are combined with calcium and magnesium ions to form water-insoluble calcium carbonate and magnesium carbonate, commonly known as water alkali. Then, as the water evaporates and concentrates, the water-alkali content increases and becomes saturated, and scale is formed.
Therefore, the addition of purified water containing a higher concentration of calcium and magnesium ions is more likely to form scale than the addition of ordinary tap water, so the addition of such purified water to the water tank has no effect on inhibiting the formation of water tank scale.
Hazard of scale in vehicle circulation waterways:
As we all know, the water tank is used for heat dissipation under normal working conditions, but once the scale is generated around the water tank, it will greatly affect the heat dissipation of the water tank. Because the thermal conductivity of scale is very low, only 1/25 of cast iron, 1/50 of brass, scale formed in the cylinder lining and the cylinder head waterway, causing the temperature of the local area to rise due to poor heat dissipation, which will lead to the engine. Cracks in the weak parts and deformation of the cylinder head.
It not only makes the cooling system heat dissipation performance worse, there is a local high temperature zone, the lubrication condition is deteriorated, the engine temperature is increased, the wear of the engine system is accelerated, and the heat pipe or the cooling system pipe is blocked, thereby greatly reducing the heat transfer efficiency. Overheating the engine directly jeopardizes the safety of the driver.
Manual cleaning method:
The water tank needs to be dismantled, and the scale is removed by artificial hammer, scraping, shovel, etc.; the descaling efficiency is low, the labor intensity is large, and it is not easy to clean, which may cause secondary damage to the water tank.
Ordinary scale cleaning agent:
The water tank needs to be dismantled, the cleaning is not thorough, the odor is large, the corrosion is strong, and the water tank is aging and the service life is shortened.
Professional water tank descaling agent:
Pour the special scale cleaning agent into the car water circulation system, let it soak, idling cycle or drive for 20-30 minutes, drain the descaling agent inside the water tank and the system, and repeatedly rinse the water to effectively remove the engine water circulation system. Scale, rust, mud and various harmful substances.
Although there is a way to clean the scale, the owner should pay attention to reduce the scale of the scale. Pay attention to the use of antifreeze. Do not use ordinary water instead of the antifreeze. Because the antifreeze can prevent the tank from being opened in addition to antifreeze. Phenomena occur, such as the use of ordinary water, can not avoid boiling pots, minerals in the water will accelerate the formation of scale.
