TTHHEE DDRRYY IICCEE BBLLAASSTTIINNGG TTEECCHHNNOOLLOOGGYY How it works

The dry ice blasting uses small pellets of dry ice sprayed through a jet nozzle with compressed air to remove paints, oil, grease, dirt, ink, adhesives and other materials you want to remove. The frigid temperature of the dry ice against the dirty surface causes adhesion to shrink and loosen from the surface. On immediate impact, the dry ice evaporates into environmentally safe and innocuous CO2 gas.

The kinetic energy ( E = ½ mv2)

The energy associated to the mass and to the speed is transferred to the surface to be cleaned / coating removal. This is the fundamental way to work either with this dry ice method or with sand / water etc. Thermal differential

When the dry ice pellets cold touch the surface, a small thermic difference occurs between the coating material, the contaminant and the substrate. This provokes cracks and the detaching facilitating the removal process.

Micro – Explosion

When the dry ice touches the surface and it transforms into innocuous CO2 gas, this tends to invade the cracks and the pores penetrating into the coating / contaminant. Then it warms up and it expands rapidly and it makes the coating / contaminant detaching from the substrate, favouring still further the coating removal or the cleaning process. Sublimation

With an inferior pressure at 5.2 bar, the solid CO2

transforms directly in gaseous state without turning into the Liquid state. But if the blasting pressure is superior at 5.2 bar ( 5.2 x 14.7 = 76.44 psi ), the CO2 in the sublimation state will show some characteristics of the Liquid CO2 while the same reaches its "triple point". Has been proved that the Liquid CO2 is a strong organic solvent so it is reasonable to suppose that this solvent action can be present when the blasting pressure is superior at 5.2 bar.


DDRRYY IICCEE

What is dry ice? The blasting agent which consists of dry ice is the solid form of CO2 ( carbon dioxide) at a temperature of - 78.5°C. CO2 is a natural medium, which has an inherent thermal energy ready to be tapped. At atmospheric pressure, solid CO2 sublimates directly to vapour without a liquid phase. This unique property means that the dry ice blast medium simply disappears, leaving only the original contaminant to be disposed of. In addition, cleaning in water sensitive areas (e.g. in the proximity of electrical cabinets) is now possible. The grade of carbon dioxide used in blasting is the same as that used in the food and beverage industry and has been specifically approved by the FDA, the EPA and the USDA. The carbon dioxide is an odourless, non-toxic gas which is used in the drinks industry as an additive in beer and mineral water. It is also used in the food industry for cooling meat and sausage etc. Carbon dioxide is a non-poisonous, liquefied gas that is both inexpensive and easily stored at work sites. Of equal importance, it is nonconductive and non-flammable. CO2 is a natural by-product of several industrial manufacturing processes such as fermentation and petrochemical refining. The CO2 given off by the above production processes is captured and stored without losses until needed. When the CO2 is returned to the atmosphere during the blasting process, no new CO2 is produced. Instead, only the original CO2 by-product is released.

How is dry ice produced? A regular supply of Liquid Carbon dioxide from a storage tank is expanded at low pressure and form the dry ice snow (at a temperature of –78,.5°C ) which is then pressed through a die by a single acting horizontal piston producing dry ice pellets in different dimension. For the successful operation of the dry ice machine it is essential to use moisture – free Liquid CO2.

The M.E.C. Microblast machines are units for cleaning equipments, machineries, plants, surfaces and so on by using pellets of solid CO2 (dry ice), blasted with an appropriate gun made on this purpose. The user’s and maintenance guide supplied with the machine reports the technical data and all the using precaution; furthermore it gives to the users different examples about “what to clean”. Especially the guide explains that the machine can also be used on electrical boxes under tension, but it specifies the right limits for this use, that means that it's possible to work on electrical boxes under tension until 1000 Volt (light tension) but not over. During the cleaning of boxes with electrical tension, the operator, with all the necessary protections and instructions, will not touch the electrical components and the CO2 isn’t absolutely an element of electrical transmission, and so for evident practical reasons the working’s distances place the operator in a very safe area. The Italian CEI rules, according to the European rules for the safety of the electrical plants, permit to work on electrical box with light tension, as for CEI 11/37 and 11/47 procedures, but even if they don't specify the cleaning of electrical box and in particular the CO2 using, without requesting any particular certification on the machines employed, or on the operators, but only requesting the necessary good sense and the use of individual protections. The laws and the Italian rules forbid works on and near machines and parts with tension over 1000 Volt. The European CE plate on the Microblast machine and the conformity declaration on the user’s and maintenance guide grant that the machines follow the requisitions of DPR 459/96, 89/392 CEE; 91/368 CEE, 93/68 CEE. These rules regulate the constructions of machines, the maintenance, the purpose for which they are on the market, so that the safety and the health of the operators are granted, respecting the limits and for the purposes he can work.

MMIICCRROOBBLLAASSTT -- BBllaasstteerr

The dual-hose system uses the flu dynamic principle named "Venturi system". The dried compressed air

flows inside a hose and it reaches the gun: inside this gun a "Venturi" nozzle, creates before, through a

constriction, an increase of the air speed, to leave it expand after. This expansion creates a vacuum and

through the second hose dry ice pellets are sucked.

Pellets and compressed air are mixed and accelerated by the blasting barrel against the object to clean.

With the double-hose system the proportion between the nozzle (of the Venturi system) and the blasting

barrel is very precise and with a very low variance to get an optimal flu dynamic performance.

In particular the counter pressures which can be generated inside the barrel, for different construction

reasons or of compressed air supply, can reduce or cancel the Venturi effect and in this way not

aspirating pellets anymore or blasting them at lower speeds.

The dual – hose system can be used for 80% of all applications.

- Simple machine

- Reliable machine

- Maintenance almost non-existent

- Machine easy to use

- Extremely regular pellets supply

- Lower pellets consumption compared with the single hose because the pellets are conveyed through the separate pellets hose to the gun without being destroyed.

- Usable on all the materials, also on the sensible ones

The single hose system uses a mechanical mixer, like a niches or holes dispenser. Pellets come in from

the upper part of the distributor and this one, by turning, takes them to its lower part where the

compressed air which will take them out to the blasting gun is injected. During this course, pellets and

compressed air are mixed together inside the single-hose, and then they are accelerated inside the

blasting barrel against the object to clean.

In the single hose system, since it is a pressure pushing system for the pellets, the flu dynamic

nozzle/barrel balance is very stable and also the work efficiency will take advantage, since any possible

counter pressures created inside different blasting barrels don't modify the blasting speed and for this

reason, with the single hose system it is possible to use all kind of barrels, also the most particular and

special ones and also with higher pressures of compressed air supply.

- All kind of nozzles can be used independently from the pressure of the air supply

- Length of the gun hose until 35-40 m.

- Possibility of vertical cleaning almost without aggression reduction

- Hard soiling, incrustation and paint can be removed more easily due to the high discharge speed
