Reason why desalinated water cannot be used for cooling the extruder barrel
The main problem with using desalinated water as cooling water for the extruder barrel is that the chemical components in the desalinated water may have a corrosive effect on the metal parts and seals inside the extruder. Furthermore, after long-term use, demineralized water can cause a layer of deposits or scale to form on metal surfaces, which can lead to blockages in the heat exchangers and pipes of the cooling system. This reduces the efficiency of the extruder and may cause machine failures. Therefore, during the production process using an extruder, it is best to use ordinary water or other suitable cooling media as the cooling water for the cylinder. .
I have encountered similar working conditions; we can talk about it
Desalinated water does not cause scale; it is ordinary cooling water that causes scale. It is precisely because scale cannot form that there is a lack of protection for the metal surface, which makes the metal prone to corrosion； The second reason is the poor cost-effectiveness; desalinated water is expensive, making it unsuitable as a cooling medium ； The third reason, I believe, is related to conductivity; desalinated water has low conductivity and is unable to transfer heat effectively, whereas it is precisely the water that is needed to reduce heat. Therefore, desalinated water is not suitable, and I think this is the most important reason
