Guides of Carbonic Snow


CARBONIC SNOW

Micropulizia with bows of snow of carbonic anhydride
The geometric conformation of the nozzle of the gun determines the dimensions of the bows of snow according to the different applications.
In the process of cleaning with snow of CO2 and' remarkable above all the phenomenon termoforetico that is gotten: the thermal gradient between the surface of the piece and the bow creates a differential thermal that produces, in turn, a moment that the separation of the contaminant provokes from the surface to treat.
- the carbonic anhydride and the industrial washing.
- carbonet: the working car with liquid carbonic anhydride.
- cleanblast: the sabbiatrice with ice of carbonic anhydride.
- sno gun: the micropulizia with bows of snow of carbonic anhydride.
The carbonic anhydride is a substance of easy availability on the market and has a power extraordinary solvent, comparable to that of the known tricloroetano 1.1.1..
Besides to specify, that the use of the carbonic anhydride for processes of industrial cleaning doesn't contribute to increase the quantity that is introduced from there in atmosphere needs.
The procedure of cleaning snow blasting foresees the use of the carbonic anhydride in the form of bows of snow for operations of micropulizia.

Carbonic L\'anidride and the industrial washing
One of the suitable products, also held interesting from the industries, the carbonic anhydride results, that had for a long time already replaced the solvents in the sector of the extraction and it started to be studied for applications in the washing to dry of the fabrics.
In Italy in the 1996 Fismet Industriale you/he/she has been the first firm builder of fittings of industrial washing to study the use of the carbonic anhydride in the machineries of cleaning.
In line with this technological evolution finalized to realize solutions really respectful impiantistiche of the environment, Fismet Industriale and' succeeded in making of his/her own clientele the whole range of the working machineries with carbonic anhydride in his/her different states available: to the solid (sabbiatura with pellets of dry ice of CO2) state, to the seed-solid (superpulizia with crystals of snow of CO2) state and the liquid state and supercritico (sgrassaggio and washing of precision)..
The carbonic anhydride and the cleaning of precision.
The carbonic anhydride has a power extraordinary solvent that allows her to cross the layer limit of the surfaces to treat, comparable to that of the known tricloroetano 1.1.1., in how much to the natural state is a solvent with characteristics chemical - physics (low superficial tension, similar density to a liquid, low stringiness) very similar to those of the traditional solvent CFC.

Proiezionisti.com: Extinguishers
The extinguishers more used in a cinema place are those to dust and those to CO2 - carbonic anhydride.
During the opening of the cylinder, thanks to the valves, the liquid pushed by the pressure inside salt through a fishing pipe, passes through the manichetta and reaches the diffuser, where, finding himself/herself/itself to the open one, instantly it evaporates a part of it, provoking an abrupt lowering of such temperature (-79 °Cs) to solidify the other part in a said icy and light mass "carbonic snow" or "dry ice"..
The carbonic snow, abandoning himself/herself/itself on the bodies that burn, it quickly turns him into gas subtracting a certain quantity of heat; the gas, that is heavier than the air, surrounds the inflammable bodies, it provokes a lowering of the concentration of oxygen, and it extinguishes the fire for suffocation.

Sicurezzaonline.it - Info-crono-file - April 13 th 2004
In this circle you/they are considered the gases of use more common or more remarkable from the point of view of the movimentazione of the loads what the oxygen, the nitrogen protoxide, the carbonic anhydride and the acetylene.
The carbonic anhydride to atmospheric pressure and temperature environment is a colorless gas, of odor and prickly taste and weakly vinegary, heavier than the air (around 1, 5 times), curtains to stratify to the ground.
The carbonic anhydride CO2 can be used to the gaseous state, liquid and solid.
The carbonic anhydride has a vast field of applications for its ownerships of: .
The carbonic anhydride, that is not a toxic gas, is contained always in the atmosphere in least percentages (around 0, 03%) and you/he/she can be born without physiological effects, also for continuous exposures, up to the 0, 5%.
The damages are very great as more the way of carbonic anhydride is elevated in the air and prolonged the time of exposure.
The carbonic snow that is formed expanding to the atmosphere liquid carbonic anhydride it has a temperature of around-78°C and therefore it provokes burns and congelation of the cutaneous zones that came to contact.

Monetti s.p.a., Wedge - Italy
If the use of the plates eutettiche is suitable for the small structures, for the great bases you/he/she has been projected an advanced system of industrial management of the transports to checked temperature, based on the employment of an accumulator of cold fed to carbonic snow.

Benefits



Yara - Surgelazione
Station of production of carbonic snow.
Equipment for the distribution of carbonic snow on boxes for the maintenance or the cooling of produced by to send what meat or fish.
System for the control of the temperature through injection checked of liquid carbonic anhydride for the transport of alimentary products.

Air Liquide Italy / Solutions for the clients / Siderurgia and metallurgy
With the evolution of the traditional productive trials, Air Liquide has not only developed numerous applications with the gases of the air (oxygen, nitrogen, argon), but also with other gases what the hydrogen, the carbonic anhydride, the compressed air in a vast sector a great deal: from the furnaces in the steelworks, from the rolling mills in the foundries.
Of great relief they are also other gases as the hydrogen, the carbonic anhydride and the compressed air: - The hydrogen, for example, together with the nitrogen in the processes of recooking of the rolling mills is used for getting the effect of particular brightness conferred to the steel to protect him/it from phenomena of degradation.
- The carbonic anhydride is used above all for eliminating the red smokes developed during the fusion preventing the formation of it with carbonic snow.
And' the so-called process of postcombustione, used from a lot of steelworks in Italy: the oxygen slowly injected in the oven reacts with the monoxide of present carbon in the smokes developing heat and carbonic anhydride to benefit of the productivity and the environmental compatibility of the fittings.

With the term "Dry Ice" you/he/she is commonly denominated the carbonic (CO2) anhydride to the solid state that is found to a temperature of around -80°C to atmospheric pressure.
Besides, in the passage from the solid state to the gaseous state, the manages carbonic anhydride an action batteriostatica and fungistatica, the proliferation of the flora microbiologica and guaranteeing the maintenance of alimentary products under the best conditions of freshness.
In fact, subliming, it produces a saturated atmosphere of carbonic anhydride, that being a dry gas, curtains to demolish the content of damp in the environment without leaving some trace of water on the foods.
The dry ice is produced for expansion of the carbonic anhydride to the liquid state, from which carbonic snow is gotten, that tablet subsequently comes in pieces of different formats: tiles, tablets, tablets and pellets, that is small cylinders of the diameter of 3 and 16 mm.
Carbonic snow can be considered to all the effects an alternative to the dry ice in how much introduces the same characteristics and you/he/she is employed for the same applications.

Uniprom - Techniques of maintenance
The carbonic anhydride or dioxide of carbon it is, for photosynthesis, source of life.
While with the mechanical cold a temperature of the order of -40°C can be reached, with the liquid nitrogen temperatures of -196°C are gotten, with the carbonic anhydride of -80°C..
The process of surgelazione criogenico gets you essentially using two fluids, the nitrogen and the carbonic anhydride, it is the most appropriate technology for the regulation of the low temperatures, allowing so to preserve the original characteristics of the refrigerated foods or frozen and to resolve numerous problems of production.
The direct injection of carbonic anhydride or liquid nitrogen, allows to cool or of crostare the alimentary products during their preparation, or to maintain them to the temperature desired during their transport.
In the anhydride carbonic version the temperature inside the room of surgelazione is maintained constant.
I exchange him/it thermal it happens both for direct sublimation of the CO2 (carbonic snow) on the product and for convection of the CO2 to the gaseous state.
A suitable system of ventilation avoids the accumulations of the carbonic snow in the tunnel optimizing the consumptions of it.

particular: to climb on to snow to beat the clear one of the egg or the whipped cream of the milk up to make her become candid and consistent; effect snow, that particular receipt of the television instruments characterized by the appearance on the screen of innumerable small white stains - in chemistry: carbonic snow, the dry ice.
As the love it is sweet when it is sincere from both the parts, it is a white heron on the snow, the eye it doesn't separate him/it.
Some Eskimo populations have in their dictionary up to 30 words that use for referring to the snow under its different conditions.
There are specific words that point out the snow while you/he/she is falling and when it is already to the ground, the simple bow of snow and that in the snowstorm, the soft snow and the hardened one, that soft and deep to the point to be asked for the use of the snow rackets to be crossed, that that accumulates on the trees and that to build the igloos, that on the suits and the that shaken by the suits, the snow that he is loosening and that that returns to freeze. ....
