Silicon fine powder is made of natural quartz (SiO2) or molten quartz (natural quartz high temperature melting, amorphous SiO2 after cooling), ball mill (or vibration, air flow), flotation, pickling, high purity water Treatment of micropowder processed by multi-course process. Silicon fine powder is a non-toxic, odorless, non-polluting inorganic non-metallic material. Since it has excellent temperature resistance, alkali corrosivity, poor thermal conductivity, high insulation, low expansion, chemical performance, high hardness, and widely used in chemical, electronics, integrated circuit (IC), electrical appliances, plastics , Paint, advanced paint, rubber, defense and other fields. With the rapid development of the high-tech field, silicon micropowder will also enter the new historical development period.China is a large country of lithium-electric materials, and the performance of lithium-ion batteries depends mainly on the performance of the materials used, and materials include positive electrode materials, negative electrode materials, electrolytes, diaphragms, and packaging materials. The most critical raw material in the lithium battery determines whether the battery's safety and battery can be large. At the same time, since the lithium ion battery positive electrode material is most proportional to the battery cost, the cost is also directly determined by the battery cost. It should be said that the development of lithium ion positive electrode materials leads the development of lithium-ion batteries. Compared with other crushing equipment, the average particle size of the lithium electrode material
gas flow pulverizer, the particle size distribution is narrow, the particle surface is smooth, the particle shape is standard, the purity is high, the activity is high, and the dispersibility is good. It is fully compliant with the preparation requirements of the electrode material, and thus is widely used.
The typical materials suitable for the Shandong Erfa airflow pulverizer are: lithium manganate, lithium cobaltate, lithium phosphate, lithium carbonate, spherical graphite, petroleum coke, asphalt coke, ternary material, nickel-hydrogen alloy, oxyphae Iron, lithium titanate, lithium manganate, and nickel-manganese acid, and the like. In addition, there is also the following features:
1, the airflow pulverizer has a plastic capability, excellent finished particle shape, can obtain a ball (potato) particle.
2, the particle size distribution is narrow, the finished product has a high density.
3. Mechanical ultrafine pulverizer, low pulverization, the finished product can reach 75% -95%.
4, the inside of the equipment can be inner lining wear-resistant material, the finished product is purified, and the equipment is small.
5, airflow classifier, use variable frequency adjustment, can be adjusted at 0.5um-100um.
6, equipment operation is stableThere is no difference and variation in the long run.
7, fully enclosed negative pressure, automation control, low noise, no dust pollution.
With the rapid development of my country's economy, there is an increase in the demand for battery new materials, plus mobile phones, laptops, digital cameras, cameras, automobiles and other products on new, efficient, environmentally friendly battery materials, my country's battery The new material market will continue to expand. The lithium battery is used as a future development direction, and its positive electrode material market development is optimistic. And
Fluidized bed airflow pulverizer has promoted the development of lithium battery materials, as a Shandong Yueza, which is a gas flow crusher, can contribute to the country's new energy career is our should be exhausted. Obligations and responsibilities.
Since the reform and opening up, China has adhered to the basic national policy of opening up to the outside world. The relevant leaders of the state have also said: "Comprehensive development of the world's development trend, economic globalization is the trend of the era of irreversible." Shandong Alpa Powder Technology Co., Ltd. As a professional powder equipment manufacturing enterprise, the Dongfeng of the policy is formed. Sales network throughout the world, with a number of overseas companies, products are exported to Australia, South Africa, Indonesia, Arab, Thailand and other regions.
