The principle of dry ice blasting is a process of physical low-temperature freezing, impact stripping, and purging stripping. The following is the principle of dry ice cleaning carbon deposits: 1. New cold spray technology: use the forced air of the air compressor to spray dry ice onto the carbon deposits of the engine, and then the dry ice particles accelerate to hit the carbon deposits, so that the carbon deposits form cracks, and the dry ice The physical low temperature freezes and embrittles the carbon deposits, reduces the adhesion of carbon deposits, so that the dirt and oil on the surface of the object are quickly frozen and peeled off; it will not cause any damage to the metal surface of the engine, nor will it affect the sealing of the engine Sex, and the Dry ice cleaning machine can quickly clean carbon deposits without dismantling the machine, and the cleaning effect is visible. 2. Physical low temperature freezing: Physical low temperature is due to the low temperature of dry ice freezing the carbon deposits in the engine. The carbon deposits are more brittle, less viscous, and the adsorption force is weakened. Coupled with compressed air impact stripping, the brittle carbon deposits form cracks. Dry ice shrinks under low temperature changes, coupled with the impact of air waves, it has the effect of cleaning carbon deposits.
