The composite board of tanks and armored vehicles has high requirements for hardness and impact resistance. This composite plate weight is 30%to 50%lighter than ordinary tank steel plates. Excellent new composite material. Ultra -fine ceramic powder can meet this requirement, and the preparation of ultra -fine ceramic powder is completed by air flow.
High -pure alumina is an important inorganic material raw material. With the continuous expansion of its application field and scope, the requirements for product quality are increasingly strict. How to improve the quality and equipment level of high -pure aluminum oxide products and occupy the high -end market are the main problems. The key to improving product quality is to ensure how to control the particle size to obtain uniform granular distribution products under the premise of ensuring purity. At present, airflow crusher technology has been applied to the preparation process of high -purity ultra -fine alumina, but less research on its process influencing factors.
The airflow crusher is a newer crushing process. It uses one high -speed airflow to hit another powder airflow, and the impact speed can be used to make the powder particles shatter. Because of the break, due to the crushing of the powder particles. Because of the crushing of the powder particles, due to the crushing of the powder particles, because the powder particles are broken. Because of Its crushed pollution -free and efficient is currently widely used in chemical, materials, metallurgy and other fields. (1) Message of airflow can effectively improve the decentralization of the powder, reduce the particle size of the powder, and make the distribution range of the powder from 0 to 60 \u0026 mu; M to 0 to 6 \u0026 mu; m; The most impact of the granularity in the process is the hierarchical wheel frequency. As the hierarchical wheel frequency increases, the granularity of alumina samples shows a significant decline. Secondly, the gas pressure and feed frequency, as the gas pressure increases, the particle size of alumina samples also increases, and as the frequency of feeding increases, the grain size of alumina is gradually decreased; (3) at the hierarchical wheel frequency 70.0Hz Under the condition of 0.8MPa, the high -purity aluminum oxide powder obtained at 4.0Hz conditions has good decentralization and particle size distribution. It can be seen through actual cases that the airflow crusher is an effective way. Nowadays, the airflow crusher produced by Qingdao Youmingke has been widely used in high -purity aluminum raw materials and has been unanimously recognized by users.
In recent years, the attention of green environmental protection and sustainable development has mentioned unprecedented heights. Whether it is Ningde era or Youmingke powder machinery, it is constantly practicing the concept of sustainable development. There may still be infinite challenges in the future, but as a large enterprise with social responsibility, Youmingke Fan Machinery will continue to adhere to technological innovation and work with partners to achieve the unified development of economic, environmental benefits and social benefits.
