1. Application scope of dry ice in industry

Tire mold, rubber mold, polyurethane mold, polyethylene mold, PET mold, foaming mold, injection mold, alloy die-casting mold, hot core box for casting and cold core box can remove residual resin, invalid release layer, carbonizing film agent and oil stain, and can open air holes. After cleaning, the mold is as bright as new.

On-line cleaning does not need to cool and disassemble the mold, which avoids the corrosion and damage of the mold by chemical cleaning method, the mechanical damage and scratch of the mold by mechanical cleaning method, and the decline of mold accuracy caused by repeated loading and unloading. Crucially, the two most time-consuming steps of removing the mold and waiting for the mold to cool can be omitted, and the downtime can be reduced by about 80%-95%.

Benefits of dry ice cleaning: dry ice cleaning can reduce downtime; Reduce equipment damage; Very effective cleaning of high-temperature equipment; Reduce or reduce the use of solvents; Improving the safety of staff; Improve maintenance efficiency; Reduce production downtime, reduce costs and improve production efficiency.

2. Application of dry ice in petrochemical industry

Clean the main fan, air compressor, fume hood, steam turbine, blower and other equipment to remove coking and carbon deposition in various heating furnaces and reactors. Clean the PVC resin on the heat exchanger; Remove oil stains, rust, hydrocarbons and dirt on the surfaces of various pressure vessels such as compressors, storage tanks and boilers; Cleaning the reaction kettle and condenser; Complex biological purification; Furnace tube cleaning, etc.

3. Application of dry ice in food/pharmacy

It can successfully remove baking residues, colloidal substances and oil stains in the oven, as well as the mixture of fresh products before baking. Effectively clean ovens, mixing and stirring equipment, conveyor belts, molded products, packaging equipment, stoves, stoves, containers, rollers, refrigerator inner walls, biscuit stoves, etc.

Benefits of dry ice cleaning: put an end to the use of harmful chemicals, and avoid production equipment contacting with harmful chemicals and generating secondary garbage; Prepare or remove bacteria such as Salmonella and Listeria, and disinfect and clean more thoroughly; Eliminate the damage of water jet cleaning to electronic equipment; Minimum equipment decomposition; Reduce downtime.

4. Application of dry ice in printing industry

It is difficult to remove ink, and the accumulation of ink on gears and guide rails will lead to poor printing quality. Dry ice cleaning can remove all kinds of oil-based and water-based inks and varnishes, clean up oil stains, accumulated inks and dyes on gears, guide rails and nozzles, and avoid the discharge of harmful wastes and solutions and personal injuries caused by harmful solvents.

5. Application scope of dry ice in automobile industry

Cleaning the doorskin, roof, carriage, car bottom and other oil stains will not cause water pollution; Cleaning of automobile carburetor and removal of automobile surface paint; Remove carbon deposits from the engine. If the carbon deposit is treated, it will take a long time to treat it with chemical agents, at least more than 48 hours, which is harmful to human body. Dry ice cleaning can completely solve the problem of carbon deposition within 10 minute, saving time and reducing cost, and the scale removal rate reaches 100%.

6. Application of dry ice in beauty industry

Some dermatologists use dry ice to treat acne, which is called cryotherapy. Because it will slightly freeze the skin.

There is a frozen substance for treating acne, which is made of ground dry ice and ethyl ketone, and sometimes some sulfur is added. Liquid nitrogen and solid dry ice can also be used as cryotherapy materials. Cryotherapy can reduce inflammation. Some time ago, the news reported that Liu Xiang used this cryotherapy to treat acne on his face. This method can reduce the generation of acne scars, but it is not used to remove scars.

7. Application of dry ice in food industry

A adding dry ice to wine, cocktail or beverage is cool and delicious when drinking, and the cup is full of smoke, which is very pleasant.

B when making ice cream, dry ice is added, and the ice cream is not easy to melt. Dry ice is especially suitable for cold storage of takeaway ice cream. Seafood dishes made in C-star hotels and restaurants, with dry ice, can create a white smoke landscape and improve the banquet level, such as making lobster sashimi.

D lobster, crab, shark fin and other seafood are frozen and refrigerated. Dry ice will not change water, and it is cleaner than water-cooled storage.

8. Application of dry ice in refrigerated transportation field

Cryopreservation and transportation of special drugs for medical use, such as plasma and vaccines.

B. Long-distance and short-distance transportation of electronic cryogenic materials and precision parts.

C. preservation and transportation of high-grade foods such as high-grade beef and mutton.

9. Application of dry ice in fire protection industry

Dry ice is used to put out fires, such as some low-temperature fire extinguishers, but the application of dry ice in this respect is less, that is, the market level is low.

In addition, excessive intake of dry ice by humans/animals can lead to death.

It is recommended to check the information.

I feel that the problem is not very clear.
