The easiest way to make your own dry ice is to prepare the materials, choose the right container, fill it with liquid carbon dioxide, seal the container, wait for the crystallization, take it with care, and pay attention to safety.

1, prepare materials:

Dry ice making requires the use of liquid carbon dioxide, sealable containers and protective gear (such as gloves, glasses, etc.).

2, choose the right container:

Use sealable containers, such as thermos cups or well-sealed plastic bags.

3, inject liquid carbon dioxide:

Inject liquid carbon dioxide into the container slowly, taking care not to overfill it.

4, seal the container:

Seal the container well to avoid gas leakage.

5, wait for crystallization:

Place the sealed container in a cool and ventilated place and wait for a period of time, the dry ice will crystallize at the bottom of the container.

6, careful access:

After the crystallization is completed, open the container to carefully access the dry ice, avoid direct contact with the dry ice or inhale its gas.

Use of dry ice

1, fire extinguishing:

Because dry ice is the solid form of carbon dioxide, it can be placed in fire extinguishers, through the carbon dioxide flame retardant properties to achieve the purpose of extinguishing the fire.

2, food industry:

Dry ice can be used to refrigerate food, because dry ice is a good coolant, so in the preservation of food can form a lower temperature environment, which is conducive to food storage.

3, mold industry cleaning:

Can remove the remaining resin, failure of the film layer, carbonized film agent, oil, open the exhaust hole, after cleaning the mold bright as new.

4, the marine industry:

For the ship shell, seawater intake valve, seawater condenser and heat exchanger, engine room, mechanical and electrical equipment, etc. cleaning, cleaner than the general use of high-pressure water jet cleaning.

5, refrigerated transportation:

Dry ice sublimation and heat absorption, can be used to refrigerate the transportation of easily rotting and deteriorating items, such as fresh seafood.

6, stage effects:

In stage performance, dry ice can create a mysterious atmosphere and effect.

7, cleaning industrial equipment:

Dry ice can be used to clean the dirt and impurities in industrial equipment, such as pipelines, reactors and so on.
