How to clean the scale left by the mold temperature machine with acid?
announcer：
Regarding the acid cleaning of the mold temperature machine, we actually need to pay attention to the need to close the cooling water outlet, and then we can actually add about 20 directly from the inlet of the mold temperature machine. %~30% of a dilute hydrochloric acid, or 15%~20% of a dilute sulfuric acid solution, soaked at room temperature for about 40~360min, at the same time, we can tap or vibrate to accelerate the scaling off.
Next, for the acid cleaning of the mold temperature machine scale, we actually should pay attention to that it should be directly connected to the high-pressure water to rinse, until it does not run out of scale particles, as far as the rinse time is concerned, probably That is about 30min. If the intervention of pickling once does not achieve the effect, we can actually pickle again, knowing to clean the scale again.
If the scale of the condenser of the mold temperature machine is more serious, it can actually be soaked with a special descaling agent. In this regard, we should pay attention to the need to poke every hour. Until it produces no gas.
Next, let's briefly talk about the physical cleaning method of mold temperature scale. The characteristics of the physical cleaning method are actually very simple. In this respect, we will actually find that it will include air cleaning and high pressure water cleaning. In addition, it refers to manual stabbing. In terms of their characteristics, it is actually different.
Blowing and cleaning of the scale of the mold temperature machine actually means that after manual brushing, we actually will chase and use a high-pressure air higher than the cooling water pressure by 0.15 to 0.2 MPa through the bypass valve of the mold temperature machine. As the cooling water is blown directly into the cooling water channel, a series of high-pressure gas-water flushes are carried out. In this way, the sediment on the inner surface of the cooling water channel can be caused to crack or fall off.
