In winter, the laser cutting machine needs to add antifreeze to ensure the normal circulation of the internal waterways. However, many people have raised the question: it's all antifreeze, so what's the difference between automotive antifreeze and antifreeze used on laser cutting machines? Can automobile antifreeze be applied to laser cutting machine? Does the laser cutting machine need coolant?
Automobile antifreeze/coolant
First of all, we need to know that antifreeze and coolant are two kinds of liquids that need to be added to ordinary household cars. We can simply understand that coolant is a kind of liquid to cool the engine, and antifreeze is a kind of liquid to prevent the coolant from freezing in winter. Generally speaking, the automobile needs to add antifreeze and coolant at the same time. One is to prevent the coolant from cracking the radiator and damaging the engine cylinder block or cover (antifreeze) due to freezing when parking in winter; The second is to ensure the constant temperature of the water tank and the normal operation of the engine.
The coolant of laser cutting machine -- deionized water
Compared with cars, laser cutting machines also need to add coolant, and antifreeze in winter. However, the coolant of the laser cutting machine is different from that of the car. The laser cutting machine needs to add deionized water. When purchasing the laser cutting machine, the water-cooled machine is a standard configuration, mainly to ensure that the temperature of the laser head and the laser is constant, and prevent the cutting effect from being affected by too high temperature in summer. Therefore, due to the limited conditions of the water-cooled machine, the laser cutting machine will not use industrial product coolant similar to that used in automobiles, and only needs deionized water; However, the automobile does not have a structure similar to a water cooler, so it is necessary to add coolant to industrial products.
Note: Although the laser cutting machine only needs to add pure water (deionized water) inside the water cooler to achieve the cooling effect in summer, mineral water cannot be used instead, because the mineral elements in the mineral water are not friendly to the water cooler itself, and the pipeline may be blocked after a long time.
Laser cutting machine antifreeze
If it comes to winter, the laser cutting machine and the car also need to add antifreeze, because the deionized water in the water cooler will freeze, so we need to add antifreeze to prevent the deionized water from freezing, which is often called antifreeze.
However, the antifreeze of the laser cutting machine is different from that of the automobile. The main reason is that the antifreeze functions of the two are different. Here we should first make it clear that: the composition of automobile coolant is complex, which mainly depends on the antifreeze for automobile; The coolant of the laser cutting machine is only deionized water with a single component, which mainly depends on the antifreeze special for the laser cutting machine. The liquid targeted by the two is different, so the composition must be very different.
In addition, the use methods of laser cutting machine and automobile antifreeze are different, and automobile antifreeze is directly prepared in good proportion; The antifreeze of Ourui laser cutting machine needs to be prepared and added in proportion according to the local temperature, because the corresponding freezing point of ethylene glycol with different concentrations is different. Generally speaking, the antifreeze and deionized water of the laser cutting machine are added at a ratio of 3:7. If the laser cutting machine in Northeast China is used for antifreeze, the ratio will be changed. The ratio of antifreeze and deionized water may be 5:5; 6:4。
To sum up, we know that the laser cutting machine needs coolant (deionized water) and antifreeze (ethylene glycol of different concentrations), and these two liquids are completely different from the coolant and antifreeze used in automobiles. We must not confuse them.
