What is dry ice blasting?
Dry ice cleaning uses compressed gas mixed with pulverized dry ice.
Spray onto the product surface through a nozzle to complete
cleaning. due to product
Surface dirt, burrs, and the substrate have different thermal
expansion coefficients.
When the ice comes out of the nozzle and contacts the product, it
instantly expands and sublimates, sucking
It absorbs a large amount of heat, causing a "subtle explosion"
effect, making dirty
Dirt, burrs, etc. quickly crack and break away to achieve the
effect of removal.

Dry ice cleaning advantages
1.Dry ice particles can be sprayed into microorganisms that are
difficult to clean with traditional methods.
Small spaces, for very precise molds or product surfaces,It won't
cause any damage at all.
2.High-density dry ice particles impact the surface more
strongly,Release more kinetic energy to remove
stubborn stains quickly and efficiently effect.
3.The unique physical properties of dry ice make it the perfect
cleaning medium. Dry ice is non-corrosive,
will not damage surfaces. Dry ice is sprayed at high speed.
4.It sublimates quickly after the surface of the object, and will
not cause secondary pollution. No chemical
solvents are used in the entire cleaning process, making the
working environment more environmentally
friendly and safer for workers.
5.Save time – no drying required, after cleaning the circuit boards
are dry and ready for packaging.
6.Environmentally friendly – no toxic wastewater is produced. The
removed residue is separated and discarded in the air filter.
7.Selective – no need to clean the entire PCB, only the side
containing flux residue High sensitivity – removes flux residue
without affecting the PCB structure
These advantages make dry ice (snow) cleaning an efficient,
economical and environmentally friendly cleaning solution.
