In situ cleaning, cleaning mold with mold rubber, mold rubber vulcanization process can cover the surface of the mold
The adhesive is heated, crosslinked and set in a closed cavity. Long-term fouling on die surfaces is inevitable. The amount of dirt increases with the passage of time, which will not only affect the appearance of the product, but also affect the dimensional accuracy of the outer edge of the product. Therefore, in order to ensure the normal use of the mold, it is necessary to clean regularly.
One: the cause of scaling
Sulfur compounds are speckled solids separated from the binder.
Brown corrosion produced by the combination of the moisture contained in the adhesive with the metal surface of the mold during vulcanization.
Solid release agent (such as talcum powder, stearate) remains on the surface of the cavity after curing.
Two: mold cleaning method.
Manual descaling, metal brush sand surface friction.
Mechanical descaling, sand blasting, water grinding, etc.
Chemical descaling, special mold cleaning.
In electrolytic descaling and alkaline electrolytic cell, water is dissolved into hydrogen and oxygen, and bubbles form on the metal surface, descaling.
Ultrasonic descaling, using the principle of frequency and wavelength to shake off the dirt in the mold cavity, and the effect is better when used together with the mold washing water.
In situ cleaning, cleaning the mold with mold rubber, mold rubber vulcanization process can cover the surface of the mold, mold fouling.
