How to prevent freezing of laser cutting machine in winter? Freeze Protection Guide

The severe winter is approaching, as the temperature gradually decreases across the country, your laser cutting equipment also needs to keep warm and add antifreeze to prevent freezing to ensure the normal operation of the equipment. If the laser cutting machine is not used for a long time, as long as the cooling water passes through, especially the cooling coolant in the laser cavity and pipeline, it must be completely cleaned.

The laser cutting machine in use is recommended to be turned on for 24 hours to ensure the internal circulation of the coolant. Note: The function of antifreeze is to assist antifreeze, and it cannot heat and keep warm. In areas where the temperature is too low, attention should be paid to the protection of equipment to avoid unnecessary losses.

Why do laser cutters add antifreeze instead of water in winter

92% to 98% of the antifreeze is ethylene glycol (ethylene glycol and ethanol are two completely different components). At present, more than 95% of the water-based antifreeze using ethylene glycol at home and abroad is compared with tap water. , The more remarkable feature of ethylene glycol is that it is antifreeze, and water cannot be antifreeze. 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.

Can antifreeze be mixed with water?

Antifreeze needs to be diluted before it can be used. It can be diluted by adding deionized water. The freezing point corresponding to different concentrations is also different. In the deployment process, the local temperature should be combined with the actual situation to meet the requirements of antifreeze and economy.

Can I use car antifreeze?

Because the liquids for the two antifreeze functions are different, the antifreeze of the laser cutting machine and the car is also different. The antifreeze for automobiles is directly formulated and contains more complex components than the antifreeze for the cutting machine. The antifreeze required for the laser cutting machine needs to be proportioned with deionized water according to the local temperature. The liquid will cause certain damage to the equipment, and it is not recommended to use it.
