In general, the CO2 device uses compressed gas as auxiliary gas and acts on an internal diaphragm valve at the same time, and when the auxiliary gas is completely opened, the pressure of the gas acting on the diaphragm valve is reduced, so that the dry ice is broken and sprayed;
the lack of monitoring the CO2 liquid flow rate, the common use of air pressure detection, but no knowledge of the CO2 state;
the auxiliary gas needs to be heated to remove condensed water formed on the surface of the product by sublimation of dry ice, generally, either the heating effect cannot be achieved, or the heating is over-temperature, the damage to other parts in the equipment is caused due to lack of temperature control, and the heating rod is not cooled after the operation is stopped, so that the service life is shortened.
Centrifugal water washing has poor cleaning effect on particles with the particle size of 5-10 microns, and meanwhile, a large amount of high-purity water is consumed for cleaning, so that resources are wasted; centrifugal dehydration can not completely remove water stains, so that baking treatment is needed, watermark marks are easy to remain after baking is finished, and the light-emitting or imaging effect of a lens is affected.
