Ultra -fine silver powder has excellent conductivity conductivity, strong antioxidant performance, better weldable performance, and low use prices. , Optical materials and other fields.其中导电浆料是超细银粉用量最大的领域，用于制作导电线路、电极等电气连接点，主要应用于厚膜集成电路、电阻器、电阻网络、电容器、MLCC、导电油墨、太阳能电池电极、 LED, printing and high -resolution conductive body, flexible circuit, conductive glue, sensitive components and other electronic components. With the arrival of the 5G era, the development of popular emerging products such as the development of all new eras, flexible screens, and 5G ceramic filters have been opened. This article will take you to see how the ultra -fine silver powder is made.
There are many ways to prepare ultra -fine silver powder, including DC arc arc plasma spraying method of heat decomposition method, thermal decomposition method, electrolytic method, ultrasound, ultrasound, ultrasound Chemical method, precipitation conversion hair, micro -emulsion method, mechanical ball grinding method, and liquid chemical reduction method. Here we mainly introduce mechanical ball mill.
Mechanical ball milling method preparation for silver powder is usually used as spherical or spherical silver powder as the silver front drive body, using the mechanical vibration and rotation of the ball mill, through the ball grinding ball to make the silver front drives strongly impacted and grinds the tissue of the silver front drive body. Structural changes are usually used to prepare slices of silver powder. It has the characteristics of low production costs, simple craftsmanship, and suitable for large -scale production. However Inner pollution of the medium and ball mill. The Gan Wei of Central South University uses spherical silver powder as the front drive, ethanol is a ball milling medium, and uses different sizes of oxidation and balls to prepare a piece of silver powder with a vibration density of 3.5g/cm3 for the ball. Preparation of silver pulp on the back of solar cells.
