When the natural gas mold temperature machine is injection molded, the formation of scale on it will actually affect its cooling effect. In this respect, the natural gas mold temperature machine is processed. At the time, it will lead to an extension of the injection molding cycle, and its production efficiency will actually be reduced.

    Because of this, we actually need to regularly clean the scale generated on the inner surface of the cooling water channel in the natural gas mold temperature machine. In this regard, in fact, it is an important thing to ensure that it can carry out normal production. Measures. In addition, there are actually two methods for cleaning the scale, which are chemical cleaning method and physical cleaning method, which can be carried out separately or in combination.

    As far as the natural gas mold temperature machine is performing the chemical cleaning method, in terms of the hydraulic oil condenser line and the cooling water channel of its barrel inlet and its injection mold cooling water channel, we actually confirm that there is already a comparison More serious scale, at this time, it can actually be manually stabbed or directly cleaned chemically.

    In fact, the inner surface of the cooling channel of the natural gas mold temperature machine is actually not contaminated by oil. In this regard, we actually do not need to perform degreasing and alkaline cleaning. In this regard, in fact, it is to be directly After acid pickling and neutralization, the operation process actually requires our attention.

    First of all, when cleaning the scale in the natural gas mold temperature machine, we must first see and neutralize. To close the water outlet of the cooling water channel in the natural gas mold temperature machine, it is necessary to add 10% soda ash solution directly from the water inlet. The temperature is actually 30～40℃ , Immediately, it should be soaked for 15 minutes, so that it can be neutralized.
