The scale on the natural gas mold temperature machine can be cleaned by chemical cleaning method
announcer:
The scale during the injection molding process of the natural gas mold temperature machine will actually form and will seriously affect its cooling effect. It is precisely because of this that the injection molding cycle will actually be extended. In fact, the production efficiency of the gas mold temperature controller will actually be reduced. Because of this, in fact, it should be noted that the scale formed on the inner surface of the cooling water channel should be cleaned regularly.

    Regarding the chemical cleaning method of the natural gas mold temperature machine, for its hydraulic oil condenser pipeline, there is the cooling water channel of the barrel inlet. In addition, in fact, it refers to the injection mold cooling water channel. In fact, we are actually It can be directly confirmed that it has a serious scale. It is precisely because of this that we should pay attention to that it should be manually stabbed or chemically cleaned directly.

     In general, the inner surface of the cooling water channel of the natural gas mold temperature machine is actually not contaminated by oil. In this respect, we actually notice that it does not need to be degreased and alkaline washed. It can be directly pickled and then neutralized.

    In the process of neutralizing and cleaning the natural gas mold temperature machine, we actually should pay attention to closing the water outlet of the cooling water channel. What we will talk about next is actually to add 10 directly from the water inlet. % Of a soda ash solution, as far as its temperature is concerned, that is to say at 30 ~ 40 ℃, next, we actually need to pay attention to soak for 15min, so that it is neutralized.

    For the neutral cleaning of natural gas mold temperature machine, we actually need to pay attention to that it should be directly connected with high-pressure water to rinse for 10 minutes. After pickling and neutralizing the natural gas mold temperature machine, in order to prevent the phenomenon of rust on the inner surface of the metal, we actually should pay attention to that it should be directly dried with compressed air.
