A sprayer is a device that uses atomization technology for coating, converting the coating liquid into mist and spraying it evenly onto the target surface. Due to their complex and diverse designs, spray coating machines are widely used in various fields, covering multiple application scenarios from thin film coating to flat panels, such as transparent conductive films for touch panels, solar cell components, and semiconductor photoresists.
Spraying machines can be divided into three categories: gas spraying systems, ultrasonic spraying systems and electrostatic spraying systems according to different spraying methods. Gas spray systems use compressed air to atomize the coating liquid and spray it onto the target surface. Although this method may result in more material loss, through complex and diverse designs, such as nozzle optimization and high-speed spray technology, uniform coating of different surfaces can be achieved. The ultrasonic spraying system uses ultrasonic vibration to make the coating liquid cover the chip at the end of the nozzle and generate a uniform fine mist, which is suitable for coating in limited areas. The electrostatic spraying system charges the coating liquid by applying static electricity and converts it into a fine mist, which is then deposited on the target surface through electrostatic attraction, effectively improving paint utilization.
These spray coating systems are widely used in areas such as insulating and conductive films for electronic components, semiconductor photoresists, hard coatings, and anti-glare, hydrophobic and oleophobic coatings. Their different characteristics and advantages allow users to choose the appropriate spraying solution according to their needs, thereby improving coating efficiency and reducing material costs.
