| titleOfInvention | A kind of dispersing method of photovoltaic front side silver paste silver powder testing graininess |
| abstract | The invention discloses a kind of dispersing methods of photovoltaic front side silver paste silver powder testing graininess, and steps are as follows for the dispersing method: a, being added to be put into supersonic wave cleaning machine after hand operated mixing after deionized water and silver powder in glass beaker and carry out ultrasonic disperse；B, laser particle analyzer switch is opened, stablize addition deionized water in rearward measurement beaker recycle plus be cleaned by ultrasonic for several times, it then proceedes to be added the deionized water of equivalent as the medium of silver powder testing graininess and adds nonionic surfactant, circulation plus ultrasound are stable to background value；C, pre-dispersed good silver powder aqueous solution is added in the measurement beaker of laser particle analyzer into sample-adding interface, until the concentration of silver powder aqueous solution can enter silver powder testing graininess step in green graticule.Medium that the present invention uses deionized water to test as silver powder partial size, nonionic surface active agent disperse as the additional ultrasonic wave of dispersing agent to obtain uniform and stable silver powder suspension, it is ensured that the accuracy and repeatability of silver powder partial size test. |
