The cleaning system sprays the dry ice particles of the dry ice cleaning machine to the working surface to be cleaned through high-pressure air, and uses the physical reflection of the temperature difference to make different substances detach at different shrinkage speeds. When the -78 degrees Celsius dry ice particles come into contact with the surface of the dirt, it will produce embrittlement, so that the dirt shrinks and loosens, and then the dry ice particles will instantly vaporize and expand 800 times, and the strong peeling force of the product will quickly and thoroughly fall off the dirt from the surface of the object, so as to achieve a fast, efficient, safe and energy-saving cleaning effect. Carbon dioxide used in dry ice cleaning** is used for industrial exhaust gases, high-altitude air separation, etc.

Dry ice washing itself does not produce carbon dioxide.

Features of Dry Ice Cleaning Machine:

1. Cost saving Because carbon dioxide is a component of the atmosphere, it is very convenient to use, cheap, and the power-consuming equipment is only an air compressor, and the dry ice is directly volatilized during the cleaning process, and there is no cost of cleaning the cleaning medium.

2. Dry cleaning process Different from steam and high-pressure water cleaning, dry ice cleaning has no damage to wires, control components, and switches. After cleaning, the possibility of rusting on the equipment is also greatly reduced compared to water cleaning. In food industry applications, dry ice cleaning significantly reduces the potential for bacterial growth compared to water cleaning.

3. Environmental safety CO2 is a non-toxic substance that meets the safety requirements of the United States Department of Agriculture (USDA), the Food and Drug Administration (FDA), and the Environmental Protection Agency (EPA). By replacing toxic chemical cleaning with dry ice, employees can avoid chemicals in the first place. Since CO2 is heavier than air, it is important to ensure ventilation and safety when operating dry ice cleaning in enclosed spaces or sunken areas.

4. Extend the service life of the equipment Unlike sand particles, walnut shells, plastic particles, and other abrasive media, dry ice particles are not abrasive. Dry ice cleaning does not damage the mold, does not destroy tolerances, and does not damage the bearings and machinery. In addition, the cleaning avoids accidental damage during the disassembly and assembly of the mold.

5. Efficient dry ice cleaning can be carried out for ** cleaning, which greatly reduces the parking time, avoids the shading, cooling, disassembly and sewage and sand treatment work required by traditional methods, and saves the drying time, so as to have efficient production efficiency and small time consumption.

6. Wide range of use For different cleaning conditions, as long as different dry ice cleaning nozzles are replaced, the cleaning working distance is improved, which can meet different needs, easy operation, safety, low cost, and considerable comprehensive benefits

Dry ice blasting deburring is actually a batch processing technology, and it is also commonplace nowadays; Dry ice deburring is a cost-effective way for manufacturers to remove burrs without damaging the surface quality of the product, and also to ensure product dimensional tolerances.

The product is easy to leave some raised small pieces of edge material in the production and molding process, this extra material - is what we call burrs, burrs are not only generated in CNC machining, but also in our injection molding die-casting products.

Dry ice cleaning technology, collectively known as cold blasting, relies on high-pressure air flow to accelerate the spraying of dry ice particles through the dry ice cleaning machine to the surface of the product to be cleaned. This process of change is called the momentum change-sublimation process. In order to achieve the dirt and impurities on the surface of the object are quickly frozen, embrittle, condensed, and fall down with the impact of the air flow; In this way, the deburring process of using dry ice will not cause harm to the product, especially the plastic material - the middle frame of the mobile phone deburring.

The advantages of dry ice cleaning are: for mold cleaning, it reduces the downtime of disassembly and can be cleaned; For product deburring, it reduces the defective product, provides production efficiency, and reduces labor costs; For the cleaning method, dry ice cleaning is a non-toxic, non-destructive and non-polluting cleaning method.

Therefore, the dry ice deburring technology for the product burr, the effect is still visible, not only in the removal process does not damage the product, the cleaning efficiency is high, but also can quickly remove the excess burr of the material, without affecting the appearance of the product.

According to the size of dry ice particles, dry ice cleaning machines are divided into: microparticle dry ice cleaning machines and granular dry ice cleaning machines; According to energy, it is divided into: electric dry ice cleaning machine and pure pneumatic dry ice cleaning machine; According to dry ice**, there are ordinary dry ice cleaning machines and ice-making cleaning machines.

There are also manual cleaning and automatic cleaning.

Dry ice cleaning principle: Dry ice particles are sprayed to the surface of the object to be cleaned through the nozzle through the high-speed operation of the air compressor, the dirt on the surface of the object is quickly frozen, which reduces the adhesion of the dirt, and then the high-pressure gas hits the dirt to make it fall off, and the volume of dry ice expands rapidly, causing the dirt to crack, so as to achieve the cleaning effect.

Dry ice cleaning machines for cleaning are based on the following three principles:

The kinetic energy of the dry ice particles, the effect of sudden changes in temperature, and the energy obtained by changing the state of the dry ice.

The efficiency of the dry ice cleaning machine depends on the following factors:

Wind pressure, compressed air pressure.

Selected nozzles (affecting impact velocity and dry ice dispersion).

The size and density of dry ice particles.

Feed rate and dry ice expansion sublimation (volume per unit area per second).

Dry ice cleaning machine is a new type of machine developed by new technology, it can be applied to many aspects, and has many characteristics and advantages that other traditional cleaning machines do not have, and the market demand is very large. In addition, now is the era of environmental protection, the meaning of environmental protection has been deeply rooted, dry ice cleaning machine because of its very little pollution, so, compared with other cleaning machines will be more clean and environmentally friendly, to the society, to their own have certain benefits. The principle of its operation is actually very simple, but its significance as a machine is very profound.

Dry ice cleaning machine.

The development and progress of the times requires not only economic development, but also the development of science and technology. Therefore, the dry ice cleaning machine came into being, it has high efficiency, fast effect, very convenient and practical, and absolutely no pollution to the air, is a relatively environmentally friendly machine. So, how does it work?

And how does it work?

The working principle of the dry ice cleaning machine used for deburring smart wearable products is similar to that of steel sand, plastic sand blasting and soda spraying, during the dry ice cleaning operation, the sprayed medium dry ice particles are accelerated in the high-pressure air flow, sprayed through the nozzle, and impact the surface to be cleaned. Dry ice cleaning is unique in that the dry ice particles vaporize at the moment of impact. The momentum of the dry ice disappears in the moment of impact.

Rapid heat exchange occurs between the dry ice particles and the cleaning surface, resulting in the rapid sublimation of solid CO2 (carbon dioxide) into gas.

Unlike other blasting media, dry ice particles are characterized by extremely low temperatures (-78) and absorb a lot of heat when vaporized. This low temperature effect gives the dry ice cleaning machine unique thermodynamic properties, which affect the mechanical properties of the adhered dirt. Thermal shock occurs due to the large temperature difference between the dry ice particles and the surface to be washed.

As the temperature of the dirt layer decreases, the brittleness increases, and the dry ice particles then break up the dirt layer.

Dry ice particles expand nearly 800 times in volume in thousandths of a second, creating a "micro-**" at the point of impact, blowing away the dirt layer.

The temperature difference between two different materials with different coefficients of thermal expansion can disrupt the bond between the two materials. For example, this thermal shock phenomenon is very noticeable when removing non-metallic dirt from metallic substances.

Since CO2 (carbon dioxide) is evaporated, no secondary waste is generated during the dry ice cleaning process, leaving only dirt that needs to be removed. Even at very high speeds, the kinetic impact of dry ice is very small compared to the sand particles, because the hardness of dry ice is not large, and it vaporizes at the moment of impact, so it does not cause damage to the surface to be cleaned.

The principle of dry ice cleaning technology is that the cleaning system sprays the dry ice particles of the dry ice cleaning machine to the working surface to be cleaned through high-pressure air, and uses the physical reflection of the temperature difference to make different substances detach at different shrinkage speeds.

Compared with ordinary cleaning methods, dry ice cleaning can reduce downtime, reduce equipment damage, and effectively clean high-temperature equipment. At the same time, it can also reduce or reduce the use of solvents, improve the safety of workers, and improve maintenance efficiency; It also reduces production downtime, reduces costs, and improves production efficiency.
