Technical issues related to dry ice cleaning

Q: Why use dry ice as the medium instead of sand or water?

A: Because the polishing power of sandblasting is very strong, the substrate may be scratched. In addition, the secondary processing of cleaning materials requires time and money.

Dry ice cleaning technology does not produce secondary pollution, and at the same time, it can clean some substrates that cannot be cleaned by water or sandblasting, such as circuit boards, electrical components, etc.

In addition, since sandblasting is not required, it is possible to clean the mold online.
The dry ice cleaning mechanism is thermally shrinkable, and degreasing cleaning is also possible because it uses volume expansion when sublimating from an individual to a gas.

Q: How much dry ice do you need?

A; It has a relationship with the cleaning substrate and the model of dry ice cleaning equipment, and the average dry ice consumption is about 30kg / h.

Q: What is the price of dry ice pellets?

A: About 6 yuan/kg, including freight. (At market prices)

Q: How effective is the dry ice cleaning?

A: Dry ice cleaning technology can be applied when lens cleaning and wheel mold cleaning, the effect is very good. No chemicals are needed, so don't worry about the chemicals remaining on the substrate.

Q: Can dry ice come in contact?

A: The temperature of dry ice is very low to minus 78.5 degrees. It is necessary to wear safety low-temperature gloves when contacting.

Q: Is there any noise in dry ice cleaning?

A: The sound from the device is about 80db to 95db. You need to wear soundproof earmuffs when operating.

Q: How much power does compressed air require?

A: The compressor capacity is from 0.4 mph to 1.4 mph. The same capacity is also required when using the factory.

Q: Are there any dirt that cannot be removed by dry ice cleaning?

A: The epoxy dye cannot be removed, the plating and the discoloration of the substrate itself.

Q: Is the equipment for cleaning precision molds the same as for ordinary molds?

A: There are two types of dry ice cleaning equipment:

3mm dry ice particle cleaner (for a wide area, serious pollution) and 0.75mm dry ice microparticle cleaner (for precision cleaning).

Q: Is carbon dioxide poisoning?

A: It will be affected in a closed environment. In this case, please install a ventilation fan or wear an oxygen mask.

Q: Is dry ice harmful to the environment?

A: Dry ice cleaning technology is also an environmental protection technology.

Liquefied carbon dioxide, which is the raw material for dry ice, can be reused and recovered from plants (such as petroleum refining and ammonia production) that produce large amounts of carbon dioxide (as a greenhouse gas) as a by-product of the reaction.
The National Environmental Research Institute has evaluated our dry ice cleaning as an environmentally friendly technology that effectively reduces waste and by-products in the manufacturing process.

Since some of the carbon dioxide released into the atmosphere is recovered and sold, this does not mean an increase in emissions. Even if the production of dry ice ceases, global emissions will not increase or decrease.
