Fundamentals of Dry Ice Blast Cleaning
Today, CO2 /
dry ice blasting is being effectively used in a wide array of applications,
from heavy slag removal to delicate semiconductor and circuit board
cleaning. Imagine a process that can be used on-line without damaging
equipment or requiring a machine "teardown". Unlike conventional
toxic chemicals, high pressure water blasting and abrasive grit
blasting, CO2 / dry ice blasting uses dry ice particles in a high
velocity air flow to remove contaminates from surfaces without the
added costs and inconvenience of secondary waste treatment and disposal.
Ice Blasting - Practicalities
paper taken from the Good Painting Practice, SSPC Painting Manual,
Volume 1, Fourth Edition, describes dry ice blasting's Basic
Principles of Operation, its Historical Development,
the Equipment and Matrials used, the Major Markets
and Applications for dry ice blasting, the FlashJet®
coatings removal process, Cleaning Rate and Cost Information,
as well as the Expected Advances in Dry Ice Blasting Technology.
/ Dry Ice Particle Blast Cleaning for the Molded Rubber Products
The use of solid
CO2 / dry ice blasting for the non-abrasive cleaning of rubber molds
without removing the molds from the press or creating a secondary
waste stream has intrigued molded rubber products manufacturers
since the mid-1980's. Today, many molded rubber product manufacturers
are aware of CO2 / dry ice blasting technology and its potential
to reduce production downtime, maintenance labor costs, and enhance
product quality and appearance. In fact, molded rubber products
manufacturers make up a major segment of the CO2 / dry ice particle
blast cleaning market worldwide.
of the Art in CO2 / Dry Ice Blast Tire Mold Cleaning
For manual, hand-held
applicator tire mold cleaning, the most notable development has
been blast nozzles that are shorter in length, lighter in weight,
operate at much lower air flow rates (and are therefore less noisy)
without sacrificing performance, and are configured for rapid interchange
from one nozzle to another. All of these new developments make the
task of manual tire mold cleaning with CO2 / dry ice pellet blast
much easier for the operator, and more acceptable and safer for
the general plant environment.
Mold Maintenance With Engineered CO2 / Dry Ice Blasting Systems
The use of solid
CO2 / dry ice blasting for the non-abrasive cleaning of tire mold
sidewalls without removing the mold from the press or creating a
secondary waste stream has intrigued tire manufacturers since the
mid-1980s. The collective experiences of those tire manufacturers
who were "early adopters" of this technology have led
to a more pragmatic approach regarding the use and benefits of solid
CO2 / dry ice blasting. The result has been the continued success
and growth of the CO2 / dry ice blasting industry with significant
support from the tire manufacturers. Mainstream technology acceptance
has arrived in particular for the CO2 / dry ice blasting technology
suppliers who listened to these pioneer customers in the tire industry,
and worked diligently with them to provide fully developed tire
mold maintenance solutions.
to Compare Dry Ice Blast Cleaning Systems
all dry ice blast systems are created equal. System comparison tests
are suggested below that should help potential buyers distinguish
between sales pitches and performance reality.
