Q. How to choose antifreeze for fiber laser cutting machine?
A: The temperature in winter is often very low. If the laser cutting machine is not kept warm, it will affect its normal use. In fact, we usually add antifreeze to keep the machine warm. So how to choose antifreeze?
(1). Name: Ethylene glycol, which can be purchased at a local hardware and chemical store, but also online, but the liquid cannot be transported.
(2). The ratio with deionized water is about 30%, that is, 70% of water and 30% of ethylene glycol.
(3). Be sure to add below 0 degrees, including 0 degrees.
(4). Ethylene glycol is not equal to ethanol (alcohol), please make a strict distinction.
(5). The full name of the purchase: ethylene glycol antifreeze.
(6). Any antifreeze cannot completely replace the deionized water and cannot be used for a long time all year round. After winter, the pipeline must be cleaned with deionized water or purified water, and the use of deionized water or purified water as the coolant must be resumed.
