Why do you need to add antifreeze to the laser cutting machine?

Inquire

Winter is coming, and the temperature will also drop. In winter, the laser cutting machine needs to add antifreeze to ensure the normal circulation of the internal waterway, so as to ensure the normal use of the laser cutting machine. So why does the laser cutting machine need to add special antifreeze? Is ordinary antifreeze okay? Let's answer for everyone below Leapion laser.

Why does the laser freeze and crack?

Because when the temperature is lower than 0℃, the liquid water condenses into a solid, and the volume of ice will be larger than that of water, which will "crack" the pipes, joints and components in the laser water cooling system. Including water coolers, cutting heads, etc.

If left alone, the severe cold weather will cause irreparable damage to the equipment. Especially for the two fiber output heads and lasers, the maintenance cost starts from 20,000 to 50,000, and the more serious is directly scrapped, and there is no maintenance value.

If the temperature is too low, if you do not add antifreeze for the laser cutting machine, it will cause the following consequences:

1. Freezing and cracking of the water pump of the chiller

2. The metal head is frozen and cracked

3. The cutting head is frozen and cracked

4. The optical fiber output head is frozen and cracked

5. The internal waterway of the laser is frozen and cracked

It can be seen that doing a good job of laser antifreeze measures is the most important thing in the maintenance of laser cutting equipment in winter.

Laser cutting machines generally use glycol-based water-based antifreeze. At present, more than 95% of water-based antifreezes using ethylene glycol are used at home and abroad. Compared with tap water, the most significant feature of ethylene glycol is antifreeze, while water cannot.

Secondly, ethylene glycol has high boiling point, low volatility, moderate viscosity and small change with temperature, and good thermal stability. Therefore, glycol type antifreeze is an ideal coolant.

Precautions for the use of antifreeze for laser cutting machine:

1. Antifreeze is not only used in winter, it can be used all year round, because its main function is to prevent freezing and cracking and boiling.

2. Any antifreeze can not completely replace deionized water and can not be used for a long time throughout the year. After winter, the pipeline must be cleaned with deionized water or purified water, and deionized water or purified water must be used as the coolant.

3. Different types of antifreeze liquids cannot be mixed to avoid chemical reactions, precipitation or bubbles, and reduce the use effect.

4. The antifreeze of the laser cutting machine needs to be mixed and added according to the different temperature in the area.

Because different concentrations of ethylene glycol correspond to different freezing points, generally speaking, the antifreeze for laser cutting machine and deionized water are added in a ratio of 3:7.

Therefore, in order to avoid unnecessary losses and troubles of the laser cutting machine, we must add antifreeze in accordance with the manufacturer's requirements to take protective measures.
