Common cleaning methods for car maintenance knowledge water tank scale

Due toWater tankThe internal water temperature has been maintained at a high temperature, so that the hydrocarbon radicals in the water will combine with calcium and magnesium ions to form water-insoluble calcium carbonate and magnesium carbonate, commonly known as water alkali. Then with the continuous evaporation and concentration of water, the water-alkali content continues to increase and reaches saturation, and scale is formed. Therefore, adding pure water with a higher concentration of calcium and magnesium ions will form scale more easily than adding ordinary tap water. Therefore, adding this pure water to the water tank has no effect on inhibiting the formation of water tank scale.

　　The harm of scale in automobile circulating waterway

Everyone knows that the water tank plays a role of heat dissipation under normal working conditions, but once lime scale is generated around the water tank, it will greatly affect the heat dissipation effect of the water tank. Because the thermal conductivity of scale is very low, it is only 1/25 of cast iron and 1/50 of brass. The scale formed on the cylinder block lining and cylinder head waterway will cause the temperature of the local area to rise due to the deterioration of heat dissipation, which will cause the engine Cracks and deformation of the cylinder head are generated in the weak parts.It doesn’t just makeCooling systemThe heat dissipation performance deteriorates, and local high temperature areas appear, which deteriorate the lubrication conditions, increase the engine temperature and accelerateEngine systemIt also blocks the radiator pipe or cooling system pipeline, which greatly reduces the heat transfer efficiency, and makes the engine overheating directly endanger the safety of the driver.

Scale cleaning method

1. Manual cleaning method: need toCarThe water tank is dismantled, and the scale is removed with an artificial hammer, scraper, shovel, etc.; the descaling efficiency is low, the labor intensity is high, it is not easy to clean, and it is easy to cause secondary damage to the water tank.

2. Ordinary scaleCleaning agent: The water tank needs to be dismantled, incomplete removal, strong odor, strong corrosiveness, easy to cause aging of the water tank and shorten its service life.

3. Professional car water tank descaling agent: it can be cleaned without disassembly, and it can also be cleaned without stopping the machine. You can directly pour the special scale cleaning agent into the car water circulation system, let it soak, cycle at idle or drive for 20-30 minutes, then drain the descaling agent inside the water tank and the system. Repeatedly flushing with water can effectively remove the engine. Scale, rust, mud and various harmful substances in the water circulation system.
