The scale cleaning of natural gas mold temperature machine can use chemical cleaning method
announcer:
Speaking of the chemical cleaning method of the scale of the natural gas mold temperature machine, the natural gas mold temperature machine is to a large extent for the hydraulic oil condenser pipe and the cooling water channel of the barrel inlet of the cylinder, and the cooling water channel of the injection mold. There is serious scale on the surface. At this time, we actually need to pay attention to manual brushing or chemical cleaning directly.

    When cleaning the scale of the natural gas mold temperature machine, the inner surface of the cooling water channel is generally not contaminated by oil, and there is no need for degreasing and alkaline cleaning. At this time, in fact, it can be directly neutralized after pickling. First of all, we should pay attention to the fact that the outlet of the cooling channel should be closed. Next, we should pay attention to adding 10% soda solution directly from the inlet. For its temperature, it will be at 30 ~ 40 ℃, soaking time is 15min, so that it is neutralized, and then, in fact, we can directly connect it with high-pressure water and rinse for 10min.

    The scale cleaning of natural gas mold temperature machine actually means that after pickling and neutralization, in order to prevent the rust phenomenon on the inner surface of the metal, we can actually use compressed air to dry it directly .

    Regarding the scale cleaning of the natural gas mold temperature machine, we can actually use the acid cleaning method. At this point, we should pay attention to the fact that the cooling water channel outlet should be closed. Next, in fact, it can be directly If necessary, add 20%-30% of a dilute hydrochloric acid or 15%-20% of a dilute sulfuric acid solution from the water inlet.

    The acid cleaning method of the scale of the natural gas mold temperature machine is actually soaked directly at room temperature for about 40 to 360 minutes. At the same time, it can actually be tapped or vibrated. At this time, it is actually It can accelerate the shedding of scale on the natural gas mold temperature machine. Next, in fact, it will be directly connected to high-pressure water for washing until no scale particles flow out.
