Dry ice blasting Baton Rouge Louisiana

Dry ice blasting involves propelling pellets at extremely high speeds. The actual dry-ice pellets are quite soft, and much less dense than other media used in blast-cleaning (i.e. sand or plastic pellets). Upon impact, the pellet sublimates almost immediately, transferring minimal kinetic energy to the surface on impact and producing minimal abrasion. The sublimation process absorbs a large volume of heat from the surface, producing shear stresses due to thermal shock. This is assumed to improve cleaning as the top layer of dirt or contaminant is expected to transfer more heat than the underlying substrate and flake off more easily.

The efficiency and effectiveness of this process depend on the thermal conductivity of the substrate and contaminant. Dry ice blasting Baton Rouge Louisiana. The rapid change in state from solid to gas also causes microscopic shock waves, which are also thought to assist in removing the contaminant. Dry ice blasting Baton Rouge Louisiana. Dry Ice Blasting is nonabrasive, nonconductive and nonflammable. Dry ice blasting Baton Rouge Louisiana. Dry Ice Blasting generates no additional waste or secondary contamination unlike media and water blasting. Dry ice blasting Baton Rouge Louisiana.

Dry ice blasting is known by several names: dry ice blasting, dry ice cleaning, CO2 blasting, dry ice dusting, and even environmentally sustainable cleaning. Cold Jet dry ice blasting is an efficient and cost-effective way for industries to maximize production capability and quality. Dry ice blasting is similar to sand blasting, plastic bead blasting or soda blasting where media is accelerated in a pressurized air stream to impact a surface to be cleaned or prepared. But that’s where the similarity ends. Dry ice blasting Baton Rouge Louisiana.

Dry Ice Blasting

Instead of using hard abrasive media to grind on a surface (and damage it), dry ice blasting uses soft dry ice, accelerated at supersonic speeds, and creates mini-explosions on the surface to lift the undesirable item off the underlying substrate.

Dry ice blast cleaning is being tried successfully in many new and different applications every day. Don’t worry if you don’t see a use you may need to be listed below. Call around to see if someone else has tried it. Here are only some of the very successful ways dry ice blasting has been used:

Adhesives

Adhesives are easily removed compared to alternative methods because the lowered temperature serves to weaken the adhesive bond. Many companies are blast cleaning old labels off containers that are being recycled. Abrasive methods will generate heat therefore failing with some types of adhesive removal. Simple glue over-runs deposited on a conveyor belt can be dry ice blast cleaning while the conveyor belt is running. Dry ice blasting Baton Rouge Louisiana.

Tool Die’s Used in Manufacturing

Dry Ice Blast Cleaning is the best method for cleaning dies. The softness of the dry ice will maintain the critical tolerances of each die better than any other cleaning method. It can also be used when the die is still hot saving turnaround time. Dry ice blasting Baton Rouge Louisiana.

Fire remediation

Dry Ice cleaning is extremely effective in removing toxic residues, soot, and associated smells after a fire. Independent dry ice blasters often work with major insurance companies over a large geographic area to quickly clean fire and smoke damaged locations. Dry ice blasting Baton Rouge Louisiana.

Food and Hospital Use

Dry Ice cleaning of the surface of products and instruments is not toxic and will stop the growth of mold, mildew and other fungi as well as stop odors at the source by the elimination of the bacterial host environment, instead of a masking agent or cover-up. Dry Ice cleaning is 100% ecologically safe, USDA rated, biodegradable and harmless to humans, animals and marine life. Dry ice blasting Baton Rouge Louisiana.

Mold Removal

Dry Ice Blast Cleaning has been proved highly successful with mold removal because the force of the spray of pellets can quickly wipe a surface clean. Many hours of time are saved. Not only is the mold removed but the top layer of wood that has the roots of the mold can be removed too. This will leave the wood clean and mold free. Dry ice blasting Baton Rouge Louisiana.

Electrical Motors

Electrical motors windings can be best cleaned in place by dry ice blast cleaning. This process is done without any moisture and results in saving hours of time for drying. The cold of the dry ice breaks the bond of the contaminate faster than solvents or steam blasting. Dry ice blasting Baton Rouge Louisiana.Only the contaminant needs to be disposed of as the dry ice evaporates into the air. The motor can be quickly heated to keep the cold metal from condensing moisture from the surrounding air when finished with the cleaning. Dry ice blasting Baton Rouge Louisiana.

Cleaning Printing Presses

Because of the precision nature of printing, it is important to keep certain parts and components continually free of foreign material for efficient operation and maintaining presses at their highest value. Owners must establish periodic cleaning and maintenance schedules of all printing machines to cut maintenance costs and provide faster setups and fewer re-runs. In a recent case, a printing facility was charged with an astronomical troubleshooting bill only to find out that the cause of the ‘doubling’ was due to clogged gripper pads. Just putting a CO2 blast cleaning machine in inexperienced hands may not be the best. Dry ice blasting Baton Rouge Louisiana.Printing machinery is very complex, compared to most industrial machinery, and there are many parts that can be compromised through careless and negligent blasting. Therefore, a properly trained crew of CO2 blast cleaners will make the world of difference in the overall integrity of printing production.

Dry-ice blasting technology can trace its roots to conventional abrasive blasting. The differences between an abrasive-blasting machine and a dry-ice blasting machine are in how they handle the blast media. Unlike sand or other media, dry ice is generally used at its sublimation temperature. Dry ice blasting Baton Rouge Louisiana.This means that a pressurized hopper system could potentially build up to dangerous amounts of pressure (see dry ice bomb). Dry ice blasting Baton Rouge Louisiana. Other differences include systems for preventing the ice from forming snowball-like jams, and different materials to allow operation at very low temperatures.

Two-hose dry-ice blasting was developed before the single-hose system. This approach is very similar to a suction-feed abrasive blast system. Compressed air is delivered in one hose, and ice pellets are sucked out of a second hose by the venturi effect. Compared to a single-hose system, the two-hose system delivers ice particles less forcefully (approximately 5% for a given air supply). Dry ice blasting Baton Rouge Louisiana.For a given amount of compressed air, two-hose systems can have less vertical distance between the machine and applicator. For most systems available today this limit is well in excess of 25 feet. Dry ice blasting Baton Rouge Louisiana. Two-hose systems are generally cheaper to produce due to a simpler delivery system. These systems are rarely seen today as they are less efficient in most applications. Their principal advantage is in allowing finer particles of ice to be delivered to the applicator as the late combination of warm air with cold ice results in less sublimation in the hose. These systems allow for more delicate surfaces to be cleaned such as in semiconductor. Dry ice blasting Baton Rouge Louisiana.

Single-hose technology was developed by Cold Jet, LLC in 1986, and uses a single hose to deliver air blasts and dry ice. Single-hose dry-ice blasters share many of the advantages of single-hose abrasive-blast systems. To avoid the potential dangers of a pressurized hopper, single-hose dry-ice blasters make use of a quickly cycling airlock. The single-hose system can use a longer hose than its double-hose counterpart without a significant drop in pressure when the ice leaves the hose. Dry ice blasting Baton Rouge Louisiana. The additional power comes at the cost of increased complexity. Dry ice blasting Baton Rouge Louisiana. Single-hose systems are used where more aggressive cleaning is an advantage. This allows heavier build-up to be cleaned and allows moderate buildup to be cleaned faster. Dry ice blasting Baton Rouge Louisiana.

Dry-ice blasting can be used to clean food processing equipment to effectively decontaminate surfaces of Salmonella enteritidis, E. coli, and Listeria monocytogenes such that these microorganisms are not detectable using conventional microbiological methods. It may also be used to clean some equipment without disassembly and without producing fire or electrical hazards. Dry ice blasting Baton Rouge Louisiana. The EPA recommends dry ice blasting as an alternative to many types of solvent-based cleaning. Dry ice blasting can clean numerous objects with differing, complex geometries at once. Due to the blast media sublimating without residue dry ice blasting finds use in the semiconductor and aerospace industries. Dry ice blasting Baton Rouge Louisiana.

Safety

Carbon dioxide is increasingly toxic starting at concentrations above 1%, and can also displace oxygen resulting in asphyxia if the equipment is not used in a ventilated area. Dry ice blasting Baton Rouge Louisiana. In addition, because carbon dioxide is heavier than air, exhaust vents are required to be at or near ground level to efficiently remove the gas. Dry ice blasting Baton Rouge Louisiana. At normal pressure dry ice is −78 °C (−108 °F) and must be handled with insulated gloves. Dry ice blasting Baton Rouge Louisiana. Eye and ear protection are required to safely use dry ice cleaning equipment. Compared to other blasting-cleaning methods, dry ice blasting produces fewer waste products and does not require clean-up of a blasting medium. The waste products can be swept up, vacuumed or washed away depending on the containment. Dry ice blasting Baton Rouge Louisiana.
