PCBA Dry Ice Cleaning Machine Combines Three Primary Factors To Remove Contaminants

Pellet Kinetic Energy
Dry ice is accelerated by compressed air through a nozzle at supersonic speeds. When the dry ice collides with the substrate being cleaned it creates a kinetic effect.This effect has the largest contribution to the cleaning process when substrates are at ambient temperatures or below.Even at high impact velocities and direct head-on impact angles, the kinetic effect of solid CO2 pellets is minimal when compared to other media (grit, sand, PMB). This is due to the relative softness of a solid CO2 particle (1.5 – 2 on the Mohs Scale of Hardness), which is not as dense and hard as other projectile media.

Thermal Shock Effect
The temperature (-109°F / -78.9°C) of the dry ice causes thermodynamic shock, which causes the contaminant to embrittle and shrink. The resulting micro-cracking helps break the bond between the surface and the contaminant.The instantaneous sublimation (phase change from solid to gas) of dry ice upon impact absorbs maximum heat from the very thin top layer of the surface contaminant. Maximum heat is absorbed due to latent heat of sublimation.The very rapid transfer of heat into the dry ice from the coating top layer creates an extremely large temperature differential between successive micro-layers within the contaminant.

Thermal-Kinetic Effect
Upon impact, the combined impact energy dissipation and extremely rapid heat transfer between the pellet and the surface causes the dry ice particles to sublimate or expand instantly and return to the natural gas state.During this phase transition from solid to gas, the volume of dry ice expands up to 800 times in a few milliseconds and lifts the contaminant off of the substrate. This is effectively a "micro-explosion" at the point of contact.

Safety Measurements When It Comes to Operating a PCBA Dry Ice Cleaning Machine

Proper ventilation
Carbon dioxide stored in a tight and poorly ventilated space with a sufficient amount can cause suffocation and discomfort. In its hard form of dry ice, prolonged skin contact can cause instant and even severe frostbite as well as skin damage due to the freezing cold nature.You can either choose Exhaust ventilation or Supply ventilation, they are all great ventilation methods to maintain and supply fresh air. In addition, air monitoring devices are greatly needed to give a much better indication of actual CO2 accumulation.

Monitor and limit exposure
According to OSHA, the legal exposure to carbon dioxide is an average of 5,000 ppm over an 8-hour workday, 40 hours per week in total, and an acute exposure limit of 30,000 ppm in 15 minutes at most. After being in touch with CO2, the person is required to stay in well-ventilated places.Operators should use a CO2 monitoring device when working with dry ice blasting in a confined space.

Proper PPE
For readers who are not familiar with the term, PPE stands for Personal Protective Equipment. When it comes to handling dry ice and operating a dry ice blasting, it is essential to:Use gloves or tongs when handling dry ice.Equip safety eyewear when dry ice is in motion and also during the operation of dry ice cleaning.

Dry ice storage
Dry ice can sublimate very quickly so choosing the right container is essential as it limits the amount of dry ice that evaporates and is safe for the user as well as reduces pressure due to evaporation.

FAQ

Q: Can Dry Ice Blast Cleaning Be Performed Indoors?

A: Dry ice blast cleaning is a safe and effective cleaning process commonly used in industrial, commercial, and even certain residential environments (mold remediation, fire restoration etc…). Pelletized dry ice is a non-toxic, non-abrasive media that sublimates into a harmless gas (CO2) which then dissipates into the atmosphere.Dry ice simply evaporates and 'disappears' as it reaches room temperature, leaving no residue or trace of debris.It simply vanishes!The concentration of CO2 produced during the dry ice sublimation process is minimal and requires no ventilators or specialized breathing equipment at all.No special precautions are necessary, other than being aware of the extremely cold (-109.3° F/-78.5°C) temperatures of dry ice pellets.

Q: What Happens to the Grease, Oil, Dirt During Dry Ice Blast Cleaning?

A: Most dirt and dry debris will fall to the floor where it can be swept or vacuumed up for proper disposal.The dry ice blast-cleaning process doesn't rely on chemicals or harsh cleaning solvents to remove the filth.The blasting process takes care of even the most stubborn, stuck-on grime rather quickly and easily.

Heavily soiled, wet, and oily areas are typically mopped up prior to dry ice blast cleaning.Some greasy areas can be pre-treated with dry, absorbent materials to facilitate even easier cleaning.But generally, most all grease and oils are 'pushed' or corralled towards a specific area where they can be 'mopped' up or absorbed by various cleaning techniques after everything has been thoroughly cleaned.

Q: What Happens to All The Dirt and Debris Afterwards?

A: All remnant debris can be disposed of on-site or contained and disposed of off-site, in compliance with all regulating laws, policies, and procedures.

Q: What Are the Requirements for a Dry Ice Blast Cleaning Crew to Operate Effectively?

A: The dry ice blast-cleaning process requires a 1 inch or larger (150 psi min) supply line of cool, dry, compressed air.For this reason, most professional ice blasting contractors will choose to provide their own compressed air supply.Air temperatures that exceed 140 degrees F will damage the internal components of the pelletized ice blasting unit.Additionally, many compressed air services build up moisture from condensation within the system.This moisture will cause havoc on the dry ice cleaning process, freezing up the ice supply, air supply, and the flow of dry ice through the blasting system.

Q: How does a dry ice cleaning machine work?

A: Dry ice cleaning- also known as dry ice blasting-uses specialized equipment to blow small, rice-sized crystals of frozen CO2 through pressurized air. The intensity of these small projectiles is so strong that it blasts off contaminants or residue on industrial equipment and surfaces.

Q: What is the process of dry ice blasting?

A: Dry ice blasting is a simple, nonabrasive cleaning process that uses CO2 pellets as impact medium for removing surface contaminants without the use of chemicals, abrasive materials, high temperatures, or steam. The solid pellets sublime directly after impact on the surface, leaving no solid residue after blasting.

Q: What are the methods of dry ice cleaning?

A: Dry ice blasting uses recycled solid carbon dioxide (CO2) pellets or MicroParticles, which are blasted at supersonic speeds and sublimate on impact, lifting dirt and contaminants off the underlying substrate. Dry ice cleaning is non-abrasive, non-conductive, non-toxic, and non-flammable.

Q: What is the science behind dry ice blasting?

A: 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.

Q: Where does the dirt go when dry ice cleaning?

Q: Why are dry ice blasting machines so expensive?

A: During the cleaning itself, the dry ice machine also uses large quantities of these grains, making a permanent supply of new bags necessary. The grains need to be produced with specialized equipment and are really difficult to supply and to store. This is what makes dry ice blasting a very expensive cleaning technique.

Q: What PSI is needed for dry ice blasting?

A: 80 psi
What type of air pressure (air compressor) do I need for dry ice blasting? Dry ice blasting systems using pellets typically consume 100 cfm (2.8 m3/min) at 80 psi (5.5 bar), while MicroParticle systems typically consume 30 cfm (0.9 m3/min) at 80 psi (5.5 bar).

Q: How much does dry ice blasting cost per square foot?

A: Around $3.50 per square foot
Pricing for dry ice blast cleaning usually starts around $3.50 per square foot, but can also range as high as $4.00 to $5.00 per square foot depending on what is being cleaned, where the cleaning is taking place, how stubborn is and how deeply the contaminant has adhered to the substrate.

Q: Is the theory of dry ice cleaning?

A: The kinetic effect: the dry ice particles being accelerated to high speed. 2. The thermal effect: the dry ice particles hit the dirt layer at -78.5° C, cool it down abruptly, it contracts and forms cracks. Due to the different coefficients of thermal expansion, the compound between the surface and the dirt is loosened.

Q: What is the temperature of dry ice cleaning?

A: Very little impact energy is transferred into the coating or substrate, so the dry ice cleaning process is considered to be non-abrasive. The temperature (-109°F / -78.9°C) of the dry ice causes thermodynamic shock, which causes the contaminant to embrittle and shrink.

Q: What is the dry ice blasting technique?

A: ‍Dry ice blasting involves propelling dry ice pellets at high speed onto a surface. The pellets, made of solid carbon dioxide (CO2), sublimate upon impact, turning from solid to gas. This process lifts dirt and contaminants without the use of abrasive materials.

Q: Is dry ice cleaning bad for the environment?

A: Dry Ice is completely environmentally friendly.Dry ice is an approved medium by the EPA, USDA & FDA, and is non-toxic, non-hazardous and inhibits mold & bacteria growth. Dry ice blasting has been effectively used in EPA, USDA, FDA, AIB and GFSI inspected/certified facilities.

Q: Does dry ice cleaning damage cars?

A: Dry ice cleaning is non-abrasive, meaning it does not damage the underlying surfaces. However, some car paints or coatings may be more sensitive than others. It is advisable to test a small inconspicuous area first to ensure the paint or clear coat is not affected negatively.

Q: What is the residue of dry ice blasting?

A: Where Does it Go? Surface cleaning with dry ice isn't just safer than chemical cleaning and sandblasting-it's also quicker, due in large part to its lack of residue. After each micro-explosion, the resulting CO2 gas dissipates into the immediate atmosphere, creating no solid or liquid waste residue.
