Three points to pay attention in the dry ice cleaning process

We all know that dry ice blasting technology is becoming more and more widely used. Dry ice cleaning has many advantages that no other cleaning method can match although dry ice cleaning method has many advantages in all aspects, such as the cleaning process does not damage the surface, easy to operate, no pollution, high cleaning efficiency. However, there are still some problems needing attention in the actual operation of dry ice cleaner.

Main advantages of the dry ice blaster

We all know that the application of dry ice blasting technology is more and more extensive. Dry ice cleaning has many advantages over many other cleaning methods. Although the dry ice blasting method has many advantages in various aspects, such as the cleaning process does not damage the surface of the object, easy operation, no pollution, low noise, high cleaning efficiency. However, there are still some problems to be aware of in the actual operation of the dry ice blasting machine.

Three points in the dry ice blasting process

  1. Removal of rust and residue: Although dry ice cleaning does not cause wear on the surface of the object, it also limits its ability to remove stubborn dirt and thick rust. For example, dry ice cleaning is less effective for those soft and elastic residues that remain in the natural rubber molding operating system. Because these dry ice pellets are bounced back when sprayed onto such residues (however, dry ice blasting to remove liquid silicone rubber (LSR) is excellent, especially for those cavity surfaces with embossments). In addition, dry ice blaster removes only those residues that the eye can see.
  2. Noise level: As with other compressed air systems, when using the dry ice blasting method for mold cleaning, the general noise will reach 102dbA, which requires better ear protection. However, when the dry ice cleaning equipment is used for a long time, even if the earplugs are inserted, the noise is still large, and the human body will be more and more irritated with the extension of time, and the earmuffs with earplugs are used at this time can play a certain protective role.
  3. Employee safety: If dry ice particles sprayed at 900 ft/s per second are sprayed onto a person, the human body is simply unable to resist. Therefore, for safety, we must wear all protective gear before handling, including: durable gloves, full face masks and long-sleeved clothes. In general, there are many workbench and equipment in the production workshop. The distance between them is usually 3~5ft. Therefore, in the dry ice cleaning operation process, we should always pay attention to whether there are people nearby, so as to avoid accidentally dropping the dirt and hurting others.
