| titleOfInvention | Preparation method and equipment for high-conductivity nano silver for PCB |
| abstract | The invention discloses a preparation method and equipment for high-conductivity nano silver for a PCB. With adoption of the preparation method, high-conductivity nano silver is prepared through adopting silver nitrate or silver perchlorate as a silver source and adopting the liquid phase reduction method. The prepared nano silver is excellent in conductivity, has an electrical resistivity of 2* 10＜-3＞ omega. cm-6.5* 10＜-3＞ omega. cm, and can be used for the PCB. The equipment comprises a dissolution kettle I, a dissolution kettle II, a silver salt compound purifying column, a reducing agent purifying column, a silver salt compound dissolution kettle, a reducing agent dissolution kettle, a silver salt compound liquid storage tank, a reducing agent liquid storage tank, a temperature control anti-corrosion reaction still, a high-efficient feeding device, a centrifugal separator, a silver recycling device, a temperature control forced air drying box, a tail gas collection treatment device, an effluent treatment device and a water ion exchange device. The preparation method is simple and fewer in working procedures; the equipment is simple in structure, requires less for large-scale production equipment, and facilitates industrialization. |
