汽車循環水路內水垢的危害？
The harm of scale in automobile circulating water circuit?
大家都知道，水箱在正常工況下是起散熱作用的，但是一旦水箱四周產生水垢，就會大大影響水箱的散熱作用。因為水垢的導熱系數很低，僅是鑄鐵的1/25，黃銅的1/50，形成于缸體襯里及缸蓋水道的水垢，使局部區域因散熱性變差而溫度上升，會導致發動機薄弱部位產生裂紋及缸蓋變形。它還不僅僅使冷卻系統散熱性能變差，出現局部高溫區，惡化潤滑條件，使發動機溫度升高，加速發動機系統的磨損；還堵塞散熱管或冷卻系統管路等，大大降低傳熱效率，使發動機過熱直接危害駕駛人員的安全。
As we all know, the water tank plays a role in heat dissipation under normal working conditions, but once the scale around the water tank is generated, it will greatly affect the heat dissipation of the water tank. Because the thermal conductivity of scale is very low, which is only 1 / 25 of that of cast iron and 1 / 50 of that of brass, the scale formed in the cylinder liner and the water channel of the cylinder head will make the temperature rise in some areas due to poor heat dissipation, which will lead to cracks in the weak parts of the engine and deformation of the cylinder head. It not only worsens the heat dissipation performance of the cooling system, causes local high temperature zone, worsens the lubrication conditions, increases the engine temperature and accelerates the wear of the engine system; It can also block the cooling pipe or cooling system pipe, greatly reduce the heat transfer efficiency, make the engine overheat, and directly endanger the safety of drivers.
此外，要避免水垢的產生，就要注意水箱冷卻液的選用。許多駕駛員不重視冷卻液的使用及優劣，通常加入水箱的只是普通的水，會造成水垢的淤積。好的防凍液不僅是低凝點，而且有其他各種功能的添加成分，能抑制泡沫、防銹、防電解和防水垢等等，所以還是提醒廣大汽車用戶要慎重選擇對水箱有益的冷卻液。
In addition, to avoid the generation of scale, it is necessary to pay attention to the selection of water tank coolant. Many drivers do not pay attention to the use of coolant and the pros and cons, usually only ordinary water into the tank, will cause scale deposition. Good antifreeze is not only a low freezing point, but also has other functions of adding ingredients, which can inhibit foam, rust, electrolysis and scale. Therefore, it is still advised that the majority of automobile users should carefully choose the coolant which is beneficial to the water tank.

                                      
汽車水箱水垢清理方法？
Cleaning method of scale in automobile water tank?
一、人工清理法：需把汽車水箱拆卸下來，用人工錘、刮、鏟等清除水垢；除垢效率低、勞動強度大，不易清除干凈，易造成水箱二次損害。
1、 Manual cleaning method: the car water tank should be disassembled, and the scale should be removed by manual hammer, scraper, shovel, etc; The scale removal efficiency is low, the labor intensity is large, it is not easy to clean, and it is easy to cause secondary damage to the water tank.
二、專業汽車水箱除垢劑：一般的清洗劑，無法徹 底清除水道內的水垢和酸性物質，有時也能泡下來大片脫落的水垢，但這樣會堵塞水道，有時要拆下水箱進行清洗。如果用質量好的強力清洗劑，不需拆卸即可清洗，還可在不停車的條件下清洗。水垢會呈現粉末狀懸浮在冷卻液中，不會堵塞發動機內的水道。所以選購水箱清洗劑時，千萬不要只圖便宜。
2、 Professional car water tank descaling agent: general cleaning agent, can not completely remove the scale and acid substances in the water channel, sometimes can bubble down large scale, but this will block the water channel, sometimes need to remove the water tank for cleaning. If you use a good quality strong cleaning agent, you can clean it without disassembly, and you can also clean it without stopping. The scale will be suspended in the coolant in powder form and will not block the water channel in the engine. So when you buy water tank cleaning agent, don't just try to be cheap.
