Using the properties and characteristics of dry ice, what are the other important uses of dry ice

1. Mold industry cleaning.

Dry ice cleaning can reduce downtime; Reduce equipment damage; Extremely effective cleaning of high-temperature equipment; reduce or reduce the use of solvents; improve staff safety; Improve maintenance efficiency; Reduce production downtime, reduce costs, and improve productivity.

2. Petrochemical power.

Clean the main fan, air compressor, smoke machine, steam turbine, blower and other equipment and all kinds of heating furnaces, reactors and other coke and charcoal removal.

3. Food and pharmaceutical industry.

Residues, gelatinous substances and grease stains from baking in the oven as well as fresh mixtures before baking can be successfully removed.

4. Printing industry.

Dry ice cleaning removes a wide range of oil-based and water-based inks and varnishes, cleans gears, rails and nozzles of oil, ink build-up and dyes to avoid the discharge of hazardous waste and solutions, as well as injuries caused by hazardous solvents.

5. Automobile and ship industry.

Dry ice cleaning can completely solve the problem of carbon deposition in less than 10 minutes, which saves time and reduces costs, and the descaling rate reaches 100%.

6. Electronics and nuclear industry.

Clean the grease and dirt inside the robots and automation equipment; Removal of integrated circuit boards, post-soldering fluxes, contaminated coatings, resins, solvent-based coatings, protective layers, and photosensitive anticorrosive agents on printed circuit boards.

The details are as follows.

Used to refrigerate food, dry ice cools at a much lower temperature than ice, and the use of dry ice can produce a low temperature of -78. In addition, when "dry ice" melts, it does not turn into a liquid like ice, and it directly evaporates into a very cool, dry carbon dioxide gas, so it has a particularly good refrigeration effect and is conducive to the storage of dry food. Used to make stage effects, because dry ice can be directly raised into low-code temperature, dry carbon dioxide gas, so it can form a virtual cloud effect, often used for stage performances.

Dry ice is a solid carbon dioxide that is liquefied into a colorless liquid under pressure and then quickly solidified at low temperatures. Now dry ice has been widely used in many fields of Zhendong.

01 Used to refrigerate food, because dry ice is a good coolant, it can form a lower temperature environment when storing food, which is conducive to food storage.

02 Used to create stage effects, because dry ice can be directly raised into low-temperature, dry carbon dioxide gas, so it can form a virtual cloud effect, which is often used for stage performances.

03 For industrial cleaning, because dry ice is easy to rise, it can be used for dirt cleaning on the surface of molds in industrial production, etc., and there is no damage to the equipment.

04 Used in the food field, edible dry ice is often added to ice cream and beverages as an "ingredient", which is cool and delicious when drinking, which greatly improves the taste of the drink.

Dry ice can be used as a refrigerant, mainly using its endothermic properties, which are physical properties.

Dry ice is solid carbon dioxide, dry ice is solid carbon dioxide, which is very volatile, and volatilization takes away a lot of heat, so it can be refrigerated.

Therefore, people use dry ice as a refrigerant. And the "white fog" in the stage effect is also caused by dry ice.

Dry ice is a solid carbon dioxide, which is obtained by condensing carbon dioxide into a colorless liquid at a pressure of kilopascals, and then quickly solidifying it at low pressure, which is very easy to sublimate.

Dry ice is a solid state of carbon dioxide and is easily sublimated. Taking advantage of this property, dry ice can be used as a refrigerant and can dislodge the surrounding oxygen, which also has a freshness preservation effect to a certain extent.

Carbon dioxide sublimation absorbs heat, the first point is that it can be used for artificial rainfall (but it will aggravate the greenhouse accordingly). Second, carbon dioxide can be used as a fire extinguishing agent, which can not only reduce the temperature, but also isolate oxygen, which works very well. (However, the combustion of magnesium metal cannot be extinguished with carbon dioxide extinguishing agent, because 2mg+CO2=2mgo+c).

1. Application in the beauty industry.

Some doctors use dry ice for pimples, which is the so-called freezing. Because it will slightly freeze the **.

There is a ** pimple freezing material that is mixed with ground dry ice and acetone and sometimes mixed with some sulfur. Liquid nitrogen and solid dry ice can also be used as materials for freezing**. Freezing ** can reduce inflammation, and some time ago the news reported that Liu Xiang used this kind of freezing ** to ** pimples on his face.

This method can reduce the appearance of acne scars, but it is not used to remove scars.

2. The application of dry ice in the food industry.

a Dry ice cubes in wine, cocktails or beverages are cool and pleasant to drink.

b Dry ice is added when making ice cream, and the ice cream does not melt easily. Dry ice is particularly suitable for refrigeration of takeaway ice cream.

C star hotels, restaurants to make seafood specialties, when the table is served with dry ice, can produce white smoke landscape guess skin, improve the level of the banquet such as making lobster sashimi.

d Frozen and refrigerated lobster, crab, shark fin and other seafood. Dry ice does not dissolve water, it is cleaner and cleaner than water ice, and is widely used in Europe, the United States, Japan and other countries.

3. Application of dry ice in the field of refrigerated transportation.

a. Low-temperature frozen medical use and low-temperature transportation of special drugs such as plasma and vaccines.

b Electronic cryogenic materials, long-distance and short-distance transportation of precision components.

c. Preservation and transportation of high-end food, such as high-grade beef and mutton.

4. Application in the field of entertainment.

It is widely used in the production of smoke on stage, theater, film and television, wedding, celebration, party effect, etc., such as some programs of the National Theater are made of dry ice.

Dry ice applications in other fields.

5. Application in the fire protection industry.

Dry ice is used for fire fighting, such as some low-temperature fire extinguishers, but dry ice is less used in this area, that is, the market degree is low;

Physical.

Dry ice is solid carbon dioxide and is very easy to sublimate.

The physical process of sublimation absorbs a lot of heat to complete.

Therefore, people use dry ice as a refrigerant. And the "white fog" in the stage effect is also caused by dry ice.

Physical properties, dry ice is solid carbon dioxide, which is very volatile, and volatilization takes away a lot of heat, so it can be refrigerated. Smoke is often found, but be careful, this smoke is not carbon dioxide! Carbon dioxide is invisible, it is (water) mist, carbon dioxide absorbs a lot of heat when it becomes a gas from a solid, so that the temperature of the surrounding air drops quickly, the air temperature drops, its solubility to water vapor becomes smaller, and the water vapor undergoes a liquefaction reaction, releasing heat, and it becomes a small droplet, which is fog.

This and summer popsicles emit "white mist" in the same meaning, are small water droplets, not other gaseous substances. Hope it helps.

Physical. Because dry ice absorbs heat during sublimation, it can be used for refrigeration.

Physical properties, dry ice sublimation takes away a lot of heat.

Dry ice sublimation is a physical property.
