Why does the new energy lithium electricity industry need to use USC dry ultrasonic dust cleaning machine
The battery production process has high requirements for environmental cleanliness, and the dust in the air enters into the lithium battery production process to increase its short-circuit risk.
With the increasingly stringent safety and consistency requirements of lithium battery products, battery manufacturers put forward higher requirements for dust removal and dehumidification in the production process.
USC dry ultrasonic dust cleaning machine, dry dust removal, closed-loop design, will not affect the humidity in the battery process and the cleanliness of the space.
The production and processing process of lithium-ion battery is complicated, considering the aspects of dust removal, including mixing, rolling, film-making, winding, welding, packaging and so on. Lithium-ion battery will produce dust or smoke in these processes. If it is not dealt with in time, it will have a great impact on product quality, damage processing equipment, and even pose a threat to the safety of employees.
The process section that needs to remove dust:
1. Coating.
Before coating, USC dry ultrasonic dust cleaning machine is used to remove dust from the material to avoid abnormal coating caused by dust adhesion.
2. Polar sheet rolling.
The coated pole needs to be further compacted to improve the energy density of the battery. 1. Before the pole is rolled, a lot of fine powder is attached to the surface of the pole, so the surface of the pole needs to be cleaned by USC dry ultrasonic dust cleaning machine. 2. During the compaction process of the roller press, a lot of fine powder is attached to the surface of the upper and lower rollers, and the surface of the roller also needs dry dust cleaning.
3. Die cutting.
When the polar piece is die-cut, it will produce dust and scraps, which need to be removed in time.
4. Winding.
Before the winding process, it is necessary to use USC to remove dust from both sides of the electrode to reduce the risk of battery short circuit.
The types of dust produced in the production process of lithium battery include both aluminum powder, which is flammable and explosive, and graphite powder, which is highly conductive and easy to adhere to. Therefore, safety is the primary factor to be considered in the selection of dedusting methods.
The advantages of Sindin USC dry ultrasonic dust cleaning machine:
1. It can avoid the increase of environmental humidity caused by wet cleaning and reduce the environment of the workshop.
2. Non-contact dedusting without any physical or chemical changes and no product damage.
3. The closed-loop system, which takes the clean air of internal circulation as the medium, will not destroy the clean balance of the workshop and will not cause secondary pollution.
4. It is more environmentally friendly to dissolve without water.
5. No need to dry, solve the time cost.
6. Customized treatment width, the first in China can be customized 3 meters dedusting width.
