1.冷卻，它可以將發(fā)動機產(chǎn)生的熱量散出，保證發(fā)動機處于好的工作溫度。

1. Cooling, which can dissipate the heat generated by the engine and ensure that the engine is at a good working temperature.

2.防凍，它可以防止隨車吊等專用車輛在寒冷冬天停車時冷卻液結(jié)冰而脹裂車輛的冷卻系統(tǒng)。

2. Antifreeze, which can prevent the cooling system of special vehicles such as truck mounted crane from cracking due to the freezing of coolant when parking in cold winter.

3.防腐蝕，它可以對冷卻系統(tǒng)的部件起到防腐保護作用。

3. Anti corrosion. It can protect the parts of the cooling system from corrosion.

4.防止水垢，冷卻液可以避免降低散熱器的散熱作用。

4. To prevent scale, coolant can avoid reducing the heat dissipation of radiator.

攪拌一體機防凍液的使用誤區(qū)：

The usage mistake of antifreeze in mixer

1.一些攪拌一體機司機認為防凍液只在冬天使用，在夏天用水代替。這是錯誤的。

1. Some mixer drivers think that antifreeze is only used in winter, instead of water in summer. This is wrong.

2.防凍液只在北方寒冷的地方使用，在南方比較溫暖的地方不用。這也是錯誤的。

2. Antifreeze is only used in cold places in the north, but not in warm places in the south. This is also wrong.

3.防凍液不只是在冬天使用，在車輛上它一年四季都要使用的，一般專用車每行駛兩年就要更換一次防凍液，這是為了保證防凍液的冰點。因為防凍液的冰點、沸點都比水箱溫度要高，常年使用防凍液，車輛的散熱效果會更加顯著。怎么才能知道防凍液的冰點是多少呢？一起來看一下：

3. Antifreeze is not only used in winter, it is used all year round in vehicles. Generally, the antifreeze is replaced every two years for special purpose vehicles, which is to ensure the freezing point of antifreeze. Because the freezing point and boiling point of antifreeze are higher than the temperature of water tank, the cooling effect of vehicles will be more significant if antifreeze is used all year round. How to know the freezing point of antifreeze? Let's see:

從發(fā)動機冷卻系統(tǒng)中放出一小杯的防凍液；然后將防凍液放入冰柜中，將冰柜的溫度逐漸往下調(diào)，檢驗什么溫度時，防凍液開始結(jié)冰，從而檢驗使用中防凍液的冰點。防凍液的顏色常見的有四種，紅色、黃色、藍色和綠色，其實防凍液本身是無色透明的液體，之所以做成鮮艷的顏色，主要是便于區(qū)分和辨別而進入一些色劑，這樣用戶在選購的時候好區(qū)分，不同顏色的防凍液是不能混用的，否則就會損壞發(fā)動機。

First, a small cup of antifreeze is discharged from the engine cooling system; Then put the antifreeze into the freezer, and gradually adjust the temperature of the freezer down. When the temperature is checked, the antifreeze begins to freeze, so as to check the freezing point of the antifreeze in use. There are four common colors of antifreeze, red, yellow, blue and green. In fact, antifreeze itself is colorless and transparent liquid. The reason why it is made into bright colors is that it is easy to distinguish and identify, and some color agents are added. In this way, users can easily distinguish when choosing antifreeze. Antifreeze of different colors cannot be mixed, otherwise the engine will be damaged.
