It Can Replace Steam Or Water Blasting
Steam
and Water Blasting has its place, but Dry Ice Blasting
may be a better alternative for you:
-
This is a dry process - electrical parts and generators
can be immediately put back into service used without
waiting to dry.
- Radioactive
contaminate removal doesn't require large storage
containers for contaminated water.
-
Mildew and mold removal are far more complete with
less chance of regeneration because of water vapor
or moisture.
- Dry
ice blasting removes more algae, sea slime, and mussels
on boat hulls, than water blasting, which allows the
organic matter to reattach sooner.
It’s
Environmentally Friendly
- Replaces
many environmentally damaging solvents.
- Since
dry ice evaporates completely as a gas it leaves no
waste. Only the material being removed must be disposed
of.
- When
dry ice blasting replaces hazardous chemical cleaners
the disposal cost of that chemical is eliminated.
It's
Safe
- Protects
surface integrity and avoids grit entrapment, making
it an effective alternative to abrasive grit blasting.
- No
residue or secondary waste to clean, so you can use
it with food processing equipment.
- Eliminating
toxic chemicals and harmful emissions makes dry ice
blast blasting environmentally safe, and it reduces
employee health risks.
- Non-flammable
- Non-explosive
- Non-abrasive
It's
Economical
- Dry
ice is readily available
- Eliminates
cleanup costs resulting from toxic chemicals or gritty
cleaning
- Reduces
the labor costs of manual maintenance
- Slashes
or eliminates waste disposal costs
- Lets
you bring cleaning equipment on-site, further reducing
your costs
It
Improves Productivity
- Can
extend equipment life
- Increases
equipment operating availability
- Eliminates
equipment disassembly and masking before cleaning
- Reduces
cleaning time — which also lowers costs
Facts
About Dry Ice
Dry ice at normal pressures does not melt into liquid
carbon dioxide, but rather “sublimates” (matter
changing from a solid to gaseous form) directly into carbon
dioxide gas. Hence it is called "dry ice" as
opposed to normal "wet” ice (frozen water).
Dry ice is produced by compressing carbon dioxide gas
to a liquid form, removing excess heat, and then letting
the liquid carbon dioxide expand quickly. This expansion
causes a drop temperature so that some of the CO2 freezes
into "snow" which is then compressed.
Different types of dry ice machines produce dry ice in
various forms, most commonly: “blocks” (10-15
kg), “nuggets” (3-5 cm x 10-14 mm), and “pellets”
(.5-1.5 cm x 3 mm). The smaller forms are more expensive,
but generally more functional. As an industrial product,
dry ice has been around for approximately 80 years and
is mainly a consumable in the food production and transport
industries. Since its invention many other applications
have been found. A more recent one is Dry Ice Blasting.
Dry ice has a temperature of - 78.5 Celsius ( -173o F).
It has a specific weight is approximately 1450kg/m3, and
is free of water (pure CO2 = 100% dry) meaning it is not
conductive. Dry ice converts to CO2 vapor on surface impact,
is free of oxygen (anti bacterial) and non-toxic (food
grade CO2). Solid Co2 constantly sublimates after formation,
even when stored in a proper insulated container. However,
there is no danger since the container's lid releases
excess gas/pressure at 1-2bar (15-30psi) through the seals.
Using high quality insulated containers with cellophane
wrapped tightly around the lid/seals, dry ice may be a
usable blasting media for up to two weeks. |
